Photoshop Gradient Banding Issues

I have tried the solutions I have read concerning this issue and none have worked for me. I have used Photoshop for a long time and this didn't used to happen. Why doesn't Adobe fix this issue??? I don't want to use nor should I be expected to use the noise blur solution to fix a problem that didn't used to be a problem. I have gotten by the past few months trying to in most ways design around using photoshop for blends but it is extremely frustrating. Here is what I get no matter what colors I am blending:
http://michaelsterlingdesign.com/banding.png
What is the dealio and is there a series of special settings that need to be set when using an Apple iMac that is only 1 year old? I love Adobe products but this is driving me mad.
Any help I can get will be greatly appreciated.

It is not just the gradient tool it is the paint brushes that have this problem as well.
So in essence you are telling me that Apple products can't use or display photoshop images because they aren't up to date with the latest display capabilities?
I use an iMac at home and a Mac Pro at work with the same display results.
Bit depth is the cause? 32 bit gives a smoother transition but slows the app way down. So in order to get smooth transitions using the gradient tool or the brushes I have to use 32 bit documents or change the colors in my document by adding noise to them?
Is this true?

Gradient banding issues in CS3

CS3 has a gradient banding problem that no-one seems to be openly acknowledging or addressing.
If i make a graduated background in either Illustrator or Photoshop there is obvious banding in the gradient fill.
I have researched the problem on the net and it seems that many people are experiencing this problem but that there is no known solution or patch form Adobe to fix this. Only useless suggestions about work arounds for this simple exercise. Interestingly several people report never experiencing this problem until they upgraded from CS to CS3. I also fit this category.
I run a mixed Mac/PC network and CS3 produces fairly large background gradients perfectly in PS on my PC, though not in Il. My macs fail to produce gradients of any useful size without significant banding in both PS and Il.
I know that many other people have this issue - when is Adode going to publish something useful to address it?

John,
Where do you get the idea that Document Raster Effects settings should match a "document resolution" of 5080 or 2540?
> "300" is way too low ( if you are referring to document resolution, not image resolution )
Document Raster Effects
is a raster image resolution setting: it's the resolution of the raster images that are created by Illustrator's raster effect features. Specifying a raster resolution that is 1:1 with an imagesetter's dpi is ridiculous.
Further, where exactly is it that you "usually" set a "document resolution" in Illustrator CS3? The document resolution setting in earlier versions was simply the flatness setting, and defaulted to "800 dpi" (which is a flatness of 3, assuming a 2400 dpi imaging device). That setting is no longer even present in Illustrator, since (as I recall) AI 10. Flatness had nothing to do with grad fills; it affects curve accuracy.
You guys are talking about a problem with banding--the OP implying that he has been investigating the problem for some time--responders even offering suggestions to "fix" it. Yet no one in this thread has yet stated any of the
specifics that are necessary to even talk about banding:
Where
is the problematic banding occurring? Paddy Rogers does not even say whether he is talking about banding
on screen or in
output.
Assuming the banding is in printed output, what kind of device is it? If it's an imagesetter, is it using PostScript level 3?
What are the CMYK color values between stops of the of the page-size grad fill?
What is the size of the page (distance the grad spans)?
What is the halftone ruling being used?
These suggested "fixes" are myths:
Rasterizing the artwork
This is nonsense. It doesn't matter if the color values across a uniform grad are from vector commands or actual colors of pixel bands. Raster grads yield banded results just as easily as vector grads do. Banding is a function of the dot size and halftone ruling of a printing device. Rasterizing doesn't magically increase the resolution of a printing device.
Setting Raster Effects Resolution to a higher value
This has nothing to do with grad fills in Illustrator. A grad fill is not a raster effect.
Transparency Flattener Settings
Again, has nothing to do with banding in grad fills. A low setting may result in pixelation, not banding.
Antialiasing
Has nothing to do with banding in graduated fills.
Paddy, you claim that you are experiencing increased banding in both Photoshop CS3 and Illustrator CS3, as compared to the CS versions of those apps. Have you actually compared the
same files being sent to the
same printing device? If so, provide the specifics of a page-size grad that reliably produces the problematic banding. Be sure to state exactly what device you are printing to.

Photoshop CC banding issue, what is the fix? And why does Adobe not address this?

I am having a issue with banding. I paint in my backgrounds but instead of a nice smooth graduation I get banding. This occurs in 8 bit and 16bit. I have changed the drawing mode to basic. I have even photographed a graduated background and it still has banding. Here is my computer info. Thanks.
Processor 2 x 2.26 GHz Quad-Core Intel Xeon
Memory 12 GB 1066 MHz DDR3 ECC
Graphics NVIDIA GeForce GT 120 512 MB
Software OS X 10.9.2 (13C1021)

There have been several others who have tried to illustrate a problem like what you describe, and it's been traditionally very difficult to distinguish between what we expect to see and something that's abnormal. There is not just a single identified problem that fits your description.
The best you can do is be very, very thorough in your descriptions, including exactly what you're doing in order to create an image where you see the problem. Include as many screen grabs as you can, concentrating on showing what you consider a good result vs. bad.
Good luck.

Gradient banding in Samsung 20 inch LCD

Now idk where to begin, ok here's the best info i can give
I just assembled a new pc for graphic work/budget gaming 2 days ago:
intel core i3 530 mhz
2 gb ddr3 ram 1333 mhz
xfx nvidia geforce gt 240 1gb ddr5
windows 7 ultimate 32-bit
Samsung Myst Eco B2030 widescreen 20 inch lcd monitor
Now when i opened an old psd which contained some brushing and gradients, i could see bands in the gradients, even the wallpaper i put had bands on it. I even noticed that everything on my lcd looks hellish sharp, and when i force my head really close, i can see small square pixels all over the l cd. Is it due to the analogue output(VGA)?, should i switch to DVI?
I use 1600x900 res (native) at 32 bit
Then to test whether all gradients look the same, i opened a new ps document and made a black to white gradient, but it was smooth, there were no bands in there. But when i made a simple white box, applied full gaussian blur, and zoomed in around 2000% i could see the gradual bands again though not as bad as in the colored psd. It seems the problem only happens when i give a glow, or blurs. Then i played Splinter Cell Conviction (everything Maxed out) and again i could see gradient bands forming up in dark places, like when i die and a small cutscene is played, i could see gradient bands on the 4 corners. What could be the problem, is it the card? the lcd? i am new to lcd monitors so i dont know how to calibrate or whatever.
Please check if anyone else can see the bands on their lcd?

Regarding calibrating your display, it's not strictly necessary, but you did mention "oversaturation" in a post above. It's certainly your call whether you want to make your color-managed applications put out calibrated color.
Re switching to DVI, that's falling out of favor... How are you currently cabled to your monitor? HDMI? VGA? You've mentioned both. DVI would CERTAINLY be better than VGA.
This "Coarse effect" you speak of... Are you talking about jaggy fonts, or what? If so, do you have Font Smoothing enabled?
When I first switched from CRTs to LCDs (in 2004) I marveled that most graphics created by people using CRTs were actually butt ugly, simply because they could not see the actual image content very clearly and tended to overlook things and overcompensate for their own monitors' shortcomings.
On a good LCD using a good interface (DVI or better) you can see every pixel as a discreet element. That's a given.
After my switch from CRT to LCD I had to reset my perceptions - I had thoughts just like yours! After a while you start to realize that what may look oversharp and harsh to you may even still be too subtle for CRT users. For some time there's been a mix of CRTs and LCDs in the world, though honestly lately I've started to ignore the former as they are truly a dying breed (just try to buy a new CRT monitor nowadays). It is not wrong to concentrate solely on making graphics look good on ultra sharp LCD monitors. Don't be too hard on yourself for what you've produced in the past, when you couldn't "see clearly" yet.
That said, I should note that there are some LCDs that are not sharp at all. From time to time people post on this forum that they have trouble seeing the Photoshop UI elements at their fixed small size, and as you're no doubt aware now with your monitor there's really no problem seeing them on a very sharp display.
You could try taking a macro photo of what you're seeing on your display that you don't like. Other than that it's very difficult to communicate about such issues on a forum.

Banding Issues with GeForce 8800

Hi,
I just installed CS4 Production Premium on a new Mac Pro. The system specs are:
2x 3 GHz Quad-Core Intel Xeon
10GB RAM
NVIDIA GeForce 8800 GT 512MB
2x 1TB SAS drives
Samsung 30" Syncmaster 305T Plus
OSX 10.5.6 (both OSX and CS4 are up to date)
When I was working in After Effects, I noticed some dramatic banding issues when lighting a scene. I was curious, so I created a gradient and the same banding was visible. I tried creating a gradient in PS, AI and Flash: same results. Consistent across all CS4 products, and the image depth (8bit, 16bit or 32bit) doesn't affect it at all. Applying a blur effect to any image also produces banding.
I tried finding some gradients through Google image search. They look fine in Firefox, but when I open them in Photoshop the banding once again pops up. Same in Preview to some extent, but not as drastic.
Two other guys in my office are running CS4 with the same monitor. We're running identically calibrated color profiles, and working in the same color space. They have no problems. The only difference between their setup and mine is that they're using Macbook Pros.
Things I have tried: turning OpenGL on/off and toggling the individual GPU settings, working in all available color spaces, working with variable DPI, using another monitor, changing the synchronized color space through Bridge, changing the conversion options (dither, engine, etc), changing the color management policies, working in CMYK/RGB/Gray/Lab, changing the pixel aspect ratio, altering the scratch disks and memory allocation, dumping my CS4 preferences and starting over... none of this affects the banding. A 16bit 72DPI image that's a straight black to white gradient consists of nothing more than 12 or so very visible steps. I'm starting to wonder if this is a graphics card issue.
All the work I'm doing is for screen, so printers don't factor into the equation. I'd appreciate any tips or suggestions anyone can offer.

Well, one thing I notice is that attempting to open the linked .png in Photoshop, it has an embedded "SyncMaster" profile.
Opening it in Photoshop CS4, maintaining that profile, I see banding (although very subtle in the second (bottom) example). The top example exhibits a stippled effect at the band edges at 100% scale.
Opening it and converting it to Adobe RGB 1998, I see almost no sign of banding in that bottom example.
Opening it as is in Preview, I see the banding again.
Creating a new radial gradient in Photoshop CS4, 1300 pixels wide, #666666 to #000000, at 100% scale, it is a smooth transition with the barest hint of banding. Also, my #666666 is noticeably lighter than in your example.
Offhand, I'm not sure which factors affect your workflow. But I doubt it is your video card unless it is set for, say 16 bit or 8 bit...

Gradient Banding

Over the years, working with Illustrator, I've come to expect that Illustrator just has issues with creating gradients, and the only way to get a good smoothly transitioned gradient is to use Photoshop. I'm really suprised that Adobe hasn't solved this by now. I've been reading posts about gradient banding only in dark shadows, that the banding goes away when printing, or people just trying to say that a particular gradient just can't be recreated due to the limitations of a mathmatically defined gradient. I understand completely that the gradients in Illustrator are mathmatically defined, but essentially, so are the gradients in Photoshop, even if they end up being rendered as a bitmap, correct? I also understand that images can have stepped gradients as a result of either color profile gamuts, or bit depth, however the banding I've run into is not a result of monitor issues, limited color gamut, bit depth, or excessively dark gradients and the banding is in Illustrator, shows up in the exported file (tiff, I've also tried rasterizing the AI file in Photoshop with 16bit bit depth and still got banding) as well as prints, because it's IN the file. Below is a Tiff file that shows a gradient created in Illustrator CS6 on the left, Photoshop in the middle and the original art from Illustrator on the right. You won't be able to see the banding in the file unless you download it and view it at 100%.
So, the question is, is there a workaround in Illustrator, or a alternate way of creating gradients directly in Illustrator that will prevent this banding that I've somehow been missing in the 10 years I've been working with it? Also, Adobe, is anyone there trying to solve this problem?
-Matt

Over the years...I've come to expect that Illustrator just has issues with creating gradients...
And what other vector drawing programs have you used which have no occurrence of gradient banding?
...and the only way to get a good smoothly transitioned gradient is to use Photoshop.
Contrary to popular misconception, raster imaging is not immune to gradient banding. Consider: Everything you view on your monitor is a raster image.
I'm really suprised that Adobe hasn't solved this by now....I understand completely that the gradients in Illustrator are mathmatically defined, but essentially, so are the gradients in Photoshop, even if they end up being rendered as a bitmap, correct?... Also, Adobe, is anyone there trying to solve this problem?
What do you expect Adobe to do about math?
I've been reading posts about gradient banding only in dark shadows, that the banding goes away when printing, or people just trying to say that a particular gradient just can't be recreated due to the limitations of a mathmatically defined gradient.
This has been discussed at length many times in this forum. What part of what you've read do you not understand, or to what specifically do you take exception?
I also understand that images can have stepped gradients as a result of either color profile gamuts, or bit depth, however the banding I've run into is not a result of monitor issues, limited color gamut, bit depth, or excessively dark gradients...
How do you know the banding you're seeing is not a result of any of those issues?
...and the banding is in Illustrator, shows up in the exported file (tiff, I've also tried rasterizing the AI file in Photoshop with 16bit bit depth and still got banding)...
Where are you viewing the Illustrator, TIFF, and Photoshop grads? (On your monitor.)
...as well as prints, because it's IN the file.
It's in what you're viewing (the print). To see if the same banding pattern is in the image file, open the image file, count the bands, and actually measure and compare the pixel color values between the bands.
Below is a Tiff file that shows a gradient created in Illustrator CS6 on the left, Photoshop in the middle and the original art from Illustrator on the right.
No, below is a JPEG assembled from screenshots from your monitor.
You won't be able to see the banding in the file unless you download it and view it at 100%.
You can see the banding at multiple zooms. The bands change because of the resampling that your video system performs when it resamples on the fly when zooming or scaling.
...is there a workaround in Illustrator, or a alternate way of creating gradients directly in Illustrator that will prevent this banding that I've somehow been missing in the 10 years I've been working with it?
There is no workaround that will prevent all banding in all grads in all situations in Illustrator or any other program. So you'll have to be much more methodical and specific in your question if you really want to understand what is going on.
All images have banding, just as all raster images have "jaggies" (square-shaped pixels). The issue in both matters is to make them fine enough to be negligible. Visible "jaggies" is a mathematical conseqence involving the factors of pixel size and halftone dot size. Similarly, visible banding is a mathematical consequence involving the factors of number of tones (for each color channel or separation ink) that an imaging device (monitor or press) can render, and the distances spanned by each possible value step.
When you send a linear grad command to a PostScript device, you are sending a command to vary from color A to color B across distance D in however many steps the device can handle. The device does what it physically can within its hardware limitations. Same is true for your monitor. But the limitations differ between the devices.
So the banding you see on your monitor differs from the banding you will see on your desktop printer and from the banding you will see on film seps and from the banding you will see on press. The specifics depend on the specifics of the artwork and the imaging systems.
Your monitor can display 32 bit color. But how many of those values are available to paint a gradient across a distance depends on how many different colors--and how different they are--to be displayed across how many monitor pixels.
Your desktop printer has a fixed number of printer spots. The printer spots are used to build up halftone dots of varying size. How many different sizes of halftone dots (how many levels of gray) the printer can build is a mathematical function between the number of printer spots and the number of halftone dots available within a given distance. If the differences in adjacent tones (for each color separation involved) is finer than the differences between possible gray levels of the halftone screen, posterization occurs and you see it as bands in a linear grad.
An imagesetter has a greater number of printer spots and can therefore build more different sizes of halftone dots for any given halftone ruling than can your desktop printer. So it is less prone to banding because it is able to render more levels of gray. But it is not immune. You can still exceed its possibilities by demanding finer differences in tone steps than it can reproduce.
Banding is quite often ameleorated in print because (depending on the number of component inks involved in the subject color), the bands occur at different places on each color separation. So the resulting bands in the composite are narrower than on the individual seps, and therefore less evident. The same principle occurs on your desktop printer, but at a courser scale, because it is still a lower resolution device.
Banding is just as likely to occur in mathematically applied linear grads in raster imaging. The rasterization is not deferred to print time, it goes ahead and occurs. But the same principle applies. You are still telling the program to change the values of a fixed number of pixels in 8-bit channels. The result is being displayed on your monitor's array of pixels. When printed, the result is being rendered on the printer's (or film's) array of halftone dots. So the banding quite likely occurs at different locations from where they occur on your monitor. In other words, I don't care what you're doing, your monitor is a poor simulation of the banding that will occur in final print. For one thing, everything you see on your monitor involves three "separations" (RGB), not four.
The myth that raster imaging is somehow magically immune to banding stems from the fact that raster images are very frequently not really linear grads, but scattered dithering patterns (otherwise known as noise). If you use a linear grad tool in a raster image program to paint a linear grad across a broad distance of pixels, you can create banding just as you would in a vector-based program. If you do, then the bands are "nailed down" (rasterization is not deferred to print time) and if the imaging device has sufficient resolution, it will faithfully reproduce that same banding.
Back when raster file size was a much greater issue than it is nowadays, there were 8-bit raster imaging programs (Color It! being one example) which could make beautiful images using only 256 different colors. How did they do it? By effective use of dithering. The differences in adjacent colors were greater than those of a 24-bit image. But they were mixed and scattered so as to simulate additional colors, just as the droplets from an airbrush spraying a single color can result in the perception of multiple tones, just as a halftone screen does the same thing. Well, the nature of raster imaging is like that. Zoom way into what looks like a smoothly graduated sky and you'll see that it is in fact a scattered mixture of different values (noise).
Vector-based grads don't involve noise. They're just mathematical commands sent to the printer's interpreter. If you must, though, you can assign noise as a raster effect to your vector objects, and it can reduce visible banding because what you would really be sending to the printer ultimately is a dithered raster image.
So you just have to use some educated (i.e.; experienced) discernment when creating grads and when interpreting what you see on your monitor. And bear the general rules-of-thumb in mind:
The greater the distance spanned, the fewer component inks involved, the smaller the color change, the lower resolution the imaging device...the greater the likelihood of banding.
Set up some simple tests using simple grads in methodically arranged different values. You can build such a test array on a single page, just as you would build an array of color chips. Print it. Study the results.

Gradient Banding in CS3

OK I've looked all over the internet, and have found no solution to this problem. I was using Illustrator CS3 and I noticed gradient banding in my project.
It's not my monitor or color profile, I've checked on several computers.
I checked in Photoshop CS3, no banding. It's an Illustrator issue only.
I'm using RGB colors, and Proof Colors is NOT on.
The tutorial I'm following is here http://www.gimpplus.com/?p=3
Here's a link to the result of the banding: http://i34.tinypic.com/par6a.jpg
I know it's subtle (because of the colors), but there's noticeable banding. I don't get why it's only Illustrator CS3 though :\

Will you be using the file in RGB or CMYK? Is the gradient banding visible on a print as well? If I click on the par6a.jpg link I see a perfect graytone gradient. Or is this not the file you uploaded?

Severe banding issue in shadow areas

Short Version: Having severe banding issues in shadow areas in Lightroom. Need to know how/what to set my color profile to to fix this issue. Lengthier description and images below.
I have read several posts here in the Lightroom forums about others who are experiencing the same type of banding issues, but I haven't seen any definitive answers on how to solve the problem.
I was able to take a couple screenshots of the issue that I am seeing. The image looks very different in Photoshop, Lightroom, Windows Photo Gallery, and also rendered in IE7. Screenshots of the image in Lightroom and the image in Photoshop are posted below at a 100% crop of the affected area. The first image is how it appears in Lightroom and the second image is how it appears in Photoshop.
From what I have read elsewhere the problem has to do with how Lightroom uses color profiles. I do not have much experience with color profiles, so I'd like to get everyone's recommendation on what color profile I should be using, and maybe a link to some information on setting color profiles and how to fix this issue. The image looks so much different in Lightroom than it does elsewhere, that I can't see myself being able to trust Lightroom to process my images.
Some info on my setup. Shoot RAW with Canon Rebel XT. Use a Dell with Pentium D running Windows Vista. Monitor is a Dell 2007FP, and currently I am using the Dell 2007FP color profile as far as I can tell.

Don, Bob!
I think it is quite obvious that the Eric's problem is not banding per se (and the related cure by fiddling with black setting), but rather about the mismatch between how the file looks in LR's Develop 100% view and how the same file (or an exported file) looks in Photoshop.
Eric!
I am afraid there is no definite answer to this problem. Indeed there are a number of Windows users that have reported this problem. A very exhaustive and inconclusive thread is this:
http://www.adobeforums.com/cgi-bin/webx?128@@.3bc3578d
The bottom line so far seems to be this:
LR on Windows uses Windows ICM to generate how the image looks on the screen, while PS uses Adobe own engine to generate this. Somehow this set-up appears not to work reliably with LR - the on-screen image in LR 100% develop differs from the same file's appearance in PS or other color managed applications. The mystery here is that other applications that seem to use Windows ICM still manage to show image correctly, but not LR. But anyway, the Windows ICM appears to be the culprit here.
The amount of difference people see depends on the complexity of the monitor profile used. LUT based Version 4.0 profiles will be affected worst - not only shadow detail, but the overall tonality and colors may be off. The best match is achieved with simple matrix based version 2.0 profiles - on my machine the mismatch occurs only in deep shadows were I see banding/splotchiness in LR and only under certain Develop settings.
(Incidentallly, on Windows XP (and older) machines one should ALWAYS use ver 2.0 profiles, as Windows ICM does not support ver 4.0 profiles. I also think that Windows ICM cannot handle LUT based profiles correctly. My own experiments showed that using LUT based monitor profile resulted in mismatch between PS CS2 and other applications (like Canon DPP), not only LR. BTW - as you are using generic monitor profile, I can almost bet that it is a matrix ver 2.0 profile (good thing).)
I am curious about the Vista thing though. I had certain hopes that this image appearance problem in LR would be eliminated on Vista, as it uses the Microsoft's new Windows Color System which incororates an updated ICM that now supports ver 4.0 profiles and reportedly has many bugs of the previous ICM fixed. However, if your report is true and the image mismatch is not due to some other factors, then it seems that Vista does not solve this.

Sudden banding issue with Mac and new Canon printer, already called tech

Good morning fellow Elementites.
I have been using Photoshop Elements 12 on my MacBook Pro 13 inch, running Maverick OS, printing to HP Photosmart Premium all-in one with no banding issues, ever.
I did want to upgrade my printer and monitor so I purchased the Canon Pixma Pro 100 and a new external LG IPS monitor to view the PSE program.
I also purchased ColorMunki Display to calibrate the monitor. Everything is operational with the recommended settings for color etc.
I printed a .tiff image and a .jpg through the PSE print function. The images that looked perfect on the new monitor and Macbook monitor printed with banding. I called Canon tech support. The man had me perform a few tasks to make sure the printer was operating correctly. We printed test sheets from the printer and they were all as they should be.
He the said he NEVER prints from PSE. He edits in PSE but prints using Canon's EZ share or print or whatever it's called, doesn't matter cause I do NOT LIKE IT AT ALL. Not to mention it is just another step in the work flow. Not to mention that I paid good money for a photo editing program of high quality and I want to use ALL the features.
He said the problem isn't the printer but the printing software instructions TO the printer via the Mac OS printer system, or something like this is what he said. He also had me download some other updates and driver files. He then had me remove the printer from my printer list and then add it back.
He then had me print the .jpg image, (it only prints .jpg which is annoying as heck,) and it came out SO BEAUTIFUL I ALMOST CRIED
I want to print this quality THROUGH PSE. Does anyone have a clue as to what to do to resolve the issue? None of the suggestions in other threads from the past seem appropriate enough.
Eager to hear,
Regards.

I have returned home and have copied down all the settings so that I may post them here before I do any more fiddling. Maybe something glaring will be spotted before I start changing things.
I opened an image in PSE 12.
I chose from the PSE menu at the top of the monitor, FILE >PRINT
A window appears with my photo and boxes and such: 1. Select Printer> CANON PRO 100-SERIES (The other printer isn't concern now).
Select Paper Size and Orientation, no problems with this or any of the other settings in this window.
I then select MORE OPTIONS button at bottom of window.
Another window opens.
There are 3 options listed on the left hand side PRINTING CHOICES which it is automatically on, CUSTOM PRINT SIZE which I haven't needed yet, and COLOR MANAGEMENT.
I select COLOR MANAGEMENT.
COLOR HANDLING is set to PRINTER MANAGES COLOR.
IMAGE SPACE is listed, not in any box, as sRGB IEC61966-2.1
PRINTER PROFILE is listed in a box that is grayed out and not selectable, as CANON IJ COLOR PRINTE...
RENDERING INTENT is set in a selectable box as RELATIVE COLORMETRIC.
(There is a little mssg below all this that reminds me to remember to enable color management in the printer preferences dialog. I was never able to find this action and after doing some research I read that this mssg is a boo boo as the function is automatic in MAC running Maverick, supposedly).
I then click OK and the box goes away.
I then click the PAGE SET UP button.
A window titled PRINT opens.
The Printer selection box says CANON PRO=100 series.
The next box always confuses me because nothing in the list appears to pertain to me when I want to print my photos. It is the Presets box.
I believe FAST PRINTING ON PLAIN PAPER is always showing when I open this window. But I don't want that so I always look to see if there is something I should choose that applies. I don't know what they mean by DEFAULT SETTINGS in this case. LAST USED SETTINGS would be ok if that was what I wanted each time I printed. FAST and FINE on Plain Paper? I have been assuming they mean plain copy paper so I don't choose that. SAVE CURRENT SETTINGS AS PRESET, I don't choose that because I haven't been sure of the settings. And the SHOW PRESETS does me no good becuase you can't change anything in there.
PAPER SIZE, not an issue at the moment.
LAYOUT button is my next stop, by now I am exhausted
I look at COLOR MATCHING which shows CANON COLOR MATCHING as the selected method. (The other choice is COLOR SYNC but I don't know anything about that one and haven't been told to change it.)
PAPER HANDLING & COVER PAGE, N/A at this time.
QUALITY & MEDIUM. I choose my paper type, paper source, print quality which for my photos I select HIGH. I don't touch COLOR OPTIONS because that is scary looking. And BORDER and MARGIN I have no issue with.
I then hit SAVE and the window closes.
Then I select PRINT in the lower right of the window that has my photo in it and from which I acessed all these other things.
Phew. So, can anyone tell me if they see anything wrong here, PLEASE.
Regards,
P.

Banding issues

I bought a MacBook Pro 17" a week ago.
I thought this computer was aimed at professionals who require CPU power and precision in what is displaied.
On my MacBook Pro display I have terrible banding issues. I bought this computer to do my work on, but now it seems I'll have to turn it in and buy a PC that will show me exactly what I need to be seeing.
Have any other seen this? (or is this what people refer to as the grain problem?)

This thread still hasn't really established what this banding looks like or when & where it's visible, (unlike the 'Gradients' thread where a graphic was posted with marks indicating where the banding occurs).
LCDtest sets all display pixels to white, red, green, blue & black & is intended AFAIK to help locate stuck pixels. If you see banding while running this, I'd suggest you have a serious hardware issue & should contact Apple for a remedy. Even if you did something such as choosing a printer profile as your monitor profile, it shouldn't cause banding on a display of a single RGB value.
Very uneven screen illumination could be referred to as 'banding' while running LCDtest, though I'd argue that it wasn't banding as much as a continuous tone gradient (which of course shouldn't be there).
These screens are one step closer than any others
were previously to the Cinema displays, especially
when calibrated with hardware devices.
They are certainly closer in terms of brightness. The screen I have is not as close as any G4 PowerBook I've worked with in terms of viewing angles & evenness of illumination. I hope it's just my screen as I really need a powerful laptop for my work, hopefully I'll get my replacement in January. Until then I remain concerned that Apple have sacrificed viewing angles & even lighting for the sake of brightness...

Gradient banding on X220 IPS screen

Over on the Faint Ghosting on X220 IPS screen thread, I mentioned (twice, actually) that I see gradient banding on my X220 IPS screen. Nobody else has brought up this issue, and at the moment it seems that I may have a defective screen.
Here's a test image to check for gradient banding: http://www.lagom.nl/lcd-test/gradient.php. View and compare how it looks on other laptop and desktop monitors. Gradients appear smooth on my desktop PC (Dell monitor and low end Radeon card) and MacBook Pro, but banding is easily visible on my X220 with IPS screen. I even see faint banding when I view this forum, the subtle gradient background at the top of each post. My display is set to 32 bit color and 60 Hz refresh.
I'll take it up with Lenovo support. Meanwhile, anybody else who has the issue can post and discuss here.

I have the exact same problem.
When there is a gradient (like on the login screen, or the webpage linked earlier) I can see the image moving for a couple of seconds. This kind of behavior from the screen also makes my eyes painful after a while.
I love this laptop otherwise, but this is a terrible quality issue. I tried to explain my problem to lenovo with no luck.
Anyway, from what I read here, it's common to most x220, what can I do.
If at least lenovo was helpful. Or if they could let me return the laptop without the absurd 15% restocking fee...
Edit: Alright, found by myself after a couple of hours searching: The moving bands when the display is "adjusting" to the new picture is in part due to Intel's power saving tech "Intel Display Power Saving Technology" which can be disabled in intel's control panel. It causes flickering of the screen in general, but mostly gradients.
For those wondering, yes, it does save some power. The computer idling with this feature uses 10 watts. Without it's 11. I don't know how it'll affect battery life, but if I really need longer battery life, I'll turn the brightness down myself.
I still notice some flickering, I'll see how it goes. The banding, while now static, is still clearly visible though.
Maybe someday they'll learn LG is not good at IPS screens (see the ipad2 fiasco too)

Banding issues using Rgrad

Hey all I'm having banding issues using rgrad, I changed it to 16 bit and float but the banding is still there and noticable, surely thre's a way to create a gradient fall off map without banding, and if so how?
Rgs,

Yes, or even 6 bits, 90% (or more) of the LCD screens on the market are TN (twisted nematic) based, which is a 6 bit -only- technology. They "simulate" an 8 bit display by dithering.
(Apple's pro monitors are all 8 bit LCD's, as are a handful of professional level LCD screens)

Remove gradient banding

Hi
I'm using Photoshop CC and I am currently trying to remove some background gradient banding seen in some corporate style photographs I've taken recently. I've basically added a gradient circle of light to the black background.
When viewed on computer the gradient works perfectly - but, when viewed on a mobile phone (which these would most likely be viewed on - on apps such as linkedin etc), the banding seems to be very apparent.
I've tried various techniques such as creating a dithering layer while working in 16bit: following this guide (Photoshop Actions to fix the banding of Photoshop's gradients.):
Create a new layer (should be topmost).
Fill it with solid 50% gray.
Make some noise: Filter > Noise > Add Noise. The settings are Amount = 25%; Distribution = Uniform; Monochromatic = checked.
Now hit Command+F (Ctrl+F on Windows) to repeat the noise filter on the same layer (if you're curious why, watch the layer's histogram as you perform the noise filter the first and second time).
Set the layer to Linear Light. A great blending mode for this purpose. The darker half of the shades is implemented as inversed linear subtraction (like Linear Burn), and the lighter half as linear addition (like Linear Dodge).
In the Layers palette, set the magic values for the layer Opacity to 1% and the Fill opacity to 19%. You could (but don't, really) read the small note below about all the gory details*.
We're done. Now lock the layer (the padlock icon in the Layers palette) so it won't react to mouse input. You can forget it exists.
I've also added noise to the gradient layer to see if that seems to help - but it doesn't really.
I'd then merge all working layers together, resize to 960 x 640, convert to 8bit and save.
Any advice would be greatly appreciated.

Thanks,

Without being able to test various approaches to solving the problem before posting one here, all that is available is to work with images you posted. In both the original and in the second image (which has increased contrast that makes the banding more apparent), making a loose lasso selection of the offending area and applying a Gaussian blur eliminated the banding. Not fancy, but it worked as a final step. Perhaps it is worth a try.

PNG alpha banding issue

Hi all,
Narg, I've been trying to export some png assets for flash from photoshop and keep getting this weird banding issue (see attached image). As you can see, the image on the bottom is the png loaded into photoshop and placed on a white background. Then, on the top is how the png looks when placed on a white background in flash. WHY?!
Please, if anyone could shed some light on this I'd be really greatful.
Just to rule out some of the more obvious responses, I've already tried the following:
- Exporting as a 24bit+alpha png from photoshop (interlaced and non-interlaced)
- Exporting as a 32bit alpha png from fireworks
- Exporting as an 8bit alpha png from fireworks
- checking the image properties in flash (losless, no smoothing)
- checking the colour space settings in all apps involved
Thanks guys n gals,
Jon

If you import your design to the library THEN put it on stage, you have a very.. very high chance to lose some quality over it. ( especially photo type thing or photoshop element )
You might want to try to import it directly to stage ( if he want to replace a thing, say yes ) to have it at its full resoltion. And for later use, if you need to put it on another stage, DONT use the library one, import it again to stage directly. ( click yes). However Ctrl +c and ctrl +v dont lose any resolution when you select the right one.
That is a bug i found in flash a couple day ago. This is not true with all element, so... be alert to that thing,
