Banding.. yes banding in gradients
First of all Im not here to waste your time. I have read pretty much every thread on here about banding in gradients and there is no solution for my problem.
Details:
Illustrator CS
I experience awful banding in almost every gradient I do. It doesn't matter what the colors are. It happens more so in darks.
I cannot rasterize my work, so I can't do the gradients in PS, I can't add noise, etc. I am currently working on something that will later be resized for an art show. I work 100% in vector and unfortunetly, it has to stay that way.
Here is an example of what I'm working with. The darks.. the banding is horrid.
Ive tried re-setting my screen profile, but Ive had people on other computers tell me that they can see the banding.
I've tried RGB vs CMKY..
I mean, I really am at an end. Most of my work is viewed digitally, but I do need it to look good in print.
I wouldn't waste your time, I have spent the last week all over the internet trying to find a solution. I would think that these simple gradients would be possible in such a high end program I paid hundreds for, but really?!
Im near tears because I mean, this is my art. I just hate that it looks so terrible.
I thank ANYONE for their help, this is becoming such an issue for me.
any updates on this?
I noticed the gorgeous tones on the splash screens too, and would like to reproduce that softness...
I get what JET is saying, but I get the banding too on even just 2 similiar tones less than 12 inches apart. But from what Jet is saying I assume he means that the screen visual is not the same as the printing outcome and does not indicate the printing outcome.
a cheap or poor screen may show banding, but printed to a 5 thousand dollar printer may come out smooth when the vector is rasterized at 300 DPI on an A4 page.
I have banding on a photoshop image here actually, but I have seen lots of artwork with smooth creamy gradients or tonal blends painted on figures in character artwork, pinups and illustrations, or how to recreate the look of the opening splash screens of the software, wish I knew how to do that, i`m using a wacom bamboo with low opacity and brush pressure determines opacity in photoshop.
here is a black to transparent gradient layed over a flat mid gray layer. 10cm long. just showing you that the screen banding is not specific to only illustrator. using PS CS5 here.
same issue goes for brushes, here I used the largest softest default brush to fill this shape, still creates streaking.

Hello I have Adobe CS4 Illustrator, I do large format prints on a Roland SC-540 printer. I my gradients I get bad results. If I have a yellow to white gradient I get blue bands through out the gradient. Is there a setting in the program to change or is it my rip software?
What color management settings? Color mode? This sounds like you are simply not using the proper profile.

Banding/Color Breaks in Gradients in CS4 After Applying Printer Profiles?S
Still pretty much new to working in Photoshop CS4 and this occurred during creating a painting with a graphics tablet rather than working on photos. I'd obtained profiles to the printers/papers at a Giclee printer's shop and had applied them to this particular painting in CS4 when a gradient I had well established within the work going from approximately fire engine red to it's blued down shadow tone developed a tannish yellow break area between the bright red and the shadow tone immediately upon application of the profile. I went ahead working on the piece figuring I probably had to pretty much redo all the coloration to a more intense level being that the application of the profile immediately dulled the picture waaaaay down presumably being that it's going on matte paper and it was during this stage that I discovered a good deal of banding of out-of-place colors throughout the overall color bar in the color selection side window (not sure of the correct term) and there were irregular, soft edged, swatches of out-of-place tones within the square gradient window. Is this normal under these circumstances?.....Does one just work around this presuming it has to do with limitations of the printer/paper whose profiles have been applied or has something gone awry? Thanks...

I'm wondering if I may have mistook some advice received here some time back that may have assumed I was working with photo images to be printed....Am I understanding correctly that, doing digital artwork from scratch in CS4 as opposed to modifying camera generated images, I should be working in CMYK rather than RGB?
In most cases, when dealing with photography, it’s much better to work in RGB. The conversion to CMYK should occur at the final output stage, whether it’s from InDesign, Illustrator, or Photoshop. That way if you are dealing with a faulty CMYK profile, you (hopefully) have the option of obtaining a better profile later on and simply re-outputting. Just make sure you soft proof in the correct CMYK space on a calibrated profiled display.
To do this using Proof Setup, make sure the rendering and black comp match what you will actually use for the final conversion. Then in the display options check “Simulate Paper Color”. If you have a good CMYK profile and an accurate display, this produces the best soft proof – it honors the file conversion that has not occured yet, then uses an Absolute Colorimetric intent to properly render paper white and black ink lab values (which are built into the CMYK profile). Absolute Colorimetric should not normally be used for file conversions but it should be used for proof conversions, and a display is a behind-the-scenes proof conversion.
This could possible affect the banding you see.
If you have elements that need to be precise CMYK numbers (good example as mentioned, 100 K text) it’s best to set up these things in another application such as InDesign. Then it’s a matter of placing the Photoshop RGB in the document, creating the black text in the document, and converting the RGB to CMYK when you export a PDF from InDesign.
Even if all you have is Photoshop, you can save a Photoshop PDF and retain editing capabilities. In this instance you can convert to CMYK in the PDF dialog. The PDF output portion of the file will be CMYK, and the native portion remains RGB. It can be a very confusing workflow without much room for error but it can work.
You can also wrap up all RGB content as a Smart Object, and convert the parent file to CMYK. There are rare instances where this is warranted, and you retain the source RGB. Also a dangerous workflow, but it’s an option nonetheless.
As mentioned 16 bit is best for source RGB, but it can slow things down a bit. If you choose to work in 8 bit, double check the gradient tool to make sure dither is on. And likewise if you have a need to convert to CMYK in Photoshop, make sure dither is enabled. (I don’t believe dither is an option with 16 bit). -

This topic first appeared in the Spiceworks CommunityHi Chris,
Hardware acceleration on or off makes absolutely no difference, i recently tried watching videos in a 100% fresh install and new profile in firefox (no addons) and the problem still occurs albiet a little slower in the new install, ie it takes a little longer to drop out of synch.
There is a noticeable difference in framerate just before the problem occurs, like a very tiny hiccup, from that point on the audio gets left further and further behind, it's remedied by clicking back a few seconds on the video play bar but this is only temporary, lately i've even noticed it happening with live streams from the BBC, once again i must stress, this doesn't happen in Chrome or Opera or IE. -
Simultaneous Dual-Band & Dual-Band II

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,
Stephen.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.

Will subtle banding in gradient print?
I apologize for yet another topic about gradients and banding, however i could not find a reassuring answer to my question.
As you can see, my gradient created in InDesign shows (subtle) banding on screen, both in InDesign as in Acrobat.
I know capable RIPs handle gradients in way that's optimized for the device to prevent banding as good as possible. But... are RIPs capable of producing better results than adobe's screen rendering?
What's the best way?
1. Trust the RIP, and send the pdf with "real" gradients (smooth shades are they called i believe) in the pdf.
OR
2. Recreate the gradient in Photoshop with dither, which makes it look perfect on screen.
The printer handles files up to pdf1.7, so assume their RIP is capable of optimizing smooth shades.I got the results of the prints. The printed versions look almost identical, but there is a noticible difference:
The real gradient:
- shows banding on screen
- shows NO banding in print! The gradient looks really clean.
The photoshop dithered gradient:
- looks better on screen (no banding)
- no banding in print either, but a VERY subtle noise (the dither) is visible
Conclusion (with this printer anyway): leave the gradient as a gradient! -

Has anyone here experienced airbrush banding, as well as gradient banding? I have my brush set to transfer, pen pressure and smoothing. It seems when I try to lay down a smooth gradient with the airbrush I get this banding effect. If I brush over the same stroke there's a dark spot that forms like a bullet eye that gets bigger and bigger. It's the same with gradients. Any idea how to fix this? Thanks.
Thanks Trevor, I tried working in 16 bit as well and I get the same thing. Here's a picture of what I'm talking about. Thanks.

DAX Dynamic Banding | Calculated Member based on Calculated Field
Good morning,
I've created a Power Pivot model that measures the blood glucose levels of clinical patients at specific times of the day. The requirement is that this metric, let's call it GlucoseLevel, is always averaged as it wouldn't make sense to sum up the values.
To meet this first requirement, I set the "Summarize By" property of the GlucoseLevel column to "Average".
The second requirement is to band the GlucoseLevel values so that groups of people can be measured by this band rather than by the individual measure values. I created a banding table in Excel and then imported it into the Power Pivot model. The banding table
has three columns (BandName, MinValue and MaxValue) and has the following values:
VERYLOW: Min Value = 0; Max Value = 3.99
OK: Min Value = 4; Max Value = 6.99
WARNING: Min Value = 7; Max Value = 10.99CRITICAL: Min Value = 11; Max Value = 30.00
It is at this point where I face my challenge. I have a GlucoseLevel measure and I have a banding table. Great. The challenge is: How do I create a calculated, dynamic
member that will look at my GlucoseLevel measure (at whatever level), do a lookup to my banding table, and then return the "BandName" column from the Banding table at that specific level? So to clarify what I mean by level: I want to be able
to view the bandings at Year level, or a Month level, or even at a week level. Then depending on what level I am at, my measure should have a Band associated to it.
I've tried to solve this issue in a couple of ways:
Attempt 1
Create a calculated column in my fact table that contains a nested IF statement to manually band my GlucoseLevel values. This works fine if I view my data at the lowest level of granularity, however
it does not work if I start looking at my data at the day, week, month etc. levels
Attempt 2
1.) Create a calculated field (not a calculated column) that averages my GlucoseLevel measure. This is cool because it will average my measure at whatever level I am viewing it at. Let's call
this field Bob...
2.) Band my measure Bob by creating another calculated field (called PatientBand). This field uses my banding table (described earlier) in conjunction with my calculated field Bob. This works perfectly, except for one big flaw: Excel sees this banding field
as a measure, and not as something that I can use as a column / row...
So my question is: Can I trick Excel into viewing my PatientBand calculated field as an attribute, and not as a measure? And if not, how do I get around this challenge? Here is the DAX formula that I used to create my second calculated field "PatientBand":
PatientBand:=CALCULATE(
VALUES (Bandings[BandName]);
FILTER (
Bandings;
Test[Bob] >= Bandings[MinValue]
&& Test[Bob] <= Bandings[MaxValue]
Thanks!So there are 2 ways that I can think of for doing that.
1) if you are only using MDX clients like Excel or Reporting services you can create a text based measure that returns the banding name. (Note that this sort of approach does not work at the moment with PowerView as it only displays numeric measures). This
would effectively let you show a label next to a reading as opposed to moving the reading under a given banding column.
Banding Name :=
CALCULATE (
VALUES ( Bands[BandName] ),
FILTER (
Bands,
[Average of GlucoseReading] >= Bands[BandMin]
&& [Average of GlucoseReading] <= Bands[BandMax]
&& NOT ( ISBLANK ( [Average of GlucoseReading] ) )
2) This next approach will show the results exactly as you had them in your sample screenshots. It just takes a slight bending of the DAX. I'm using a SUMX here, not because I want to sum anything, but because the "X" version of SUMX basically loops over
every row in the specified table and sums the expression in the second parameter. I have setup the second parameter so that it only returns a single value for the average if it is in the appropriate banding.
Banded Average:=IF (
HASONEVALUE ( Bands[BandName] ),
SUMX(
'Bands',
IF (
NOT ( ISBLANK ( [Average of GlucoseReading] ) )
&& [Average of GlucoseReading] >= MIN ( Bands[BandMin] )
&& [Average of GlucoseReading] <= MIN ( Bands[BandMax] ),
AVERAGE(Readings[GlucoseReading]),
BLANK()
,AVERAGE(Readings[GlucoseReading])

According to HTC.com, this phone has the 1800 MHz LTE band (LTE band 3).
I am currently in Australia, using a Telstra LTE SIM, and I can't pick up LTE on my phone.
I tested this SIM in another phone and it gets LTE, so the problem isn't the lack of reception in my area or the SIM.
I get 3G and H data but no LTE.
I know Telstra uses 1800 MHz for LTE.
I tried changing from Global to GSM mode and all the other modes as well as all the options available in the phoneinfo app.
It seems like this device has the 1800 MHz LTE band blocked, what can be done about this?
Thanks!Also experiencing the same thing here. Second M8 (previous one replaced for multiple issues including this). When 4G/LTE is enabled my data connection continuously drops; resulting in failed sms (both sending and receiving), cut off of streaming and http services. With LTE disabled it works fine. This is not a solution and I refuse to 'make do' with slow 3G speeds. Enabling & disabling Airplane mode also gets it working again, if only for 5 minutes. There IS a permanent solution/fix – for rooted users only – but I don't want to root my device. Went in to the store and they want me to send it away for a 3rd replacement. Completely redundant as I know the next phone I'll receive will have the same issue. Frustrating.

im tryin to make a list of bands using my itunes playlist as the file (i made a txt file copy of it) it goes through like 40 bands and then just stops for some reason....
import java.io.*;

if (leftSeparatorIndex != -1) {
System.out.print(line);
rightSeparatorIndex = line.indexOf("{", leftSeparatorIndex);
if (rightSeparatorIndex != -1) {
band = line.substring(leftSeparatorIndex, rightSeparatorIndex);
if (!pband.equals(band)) {
System.out.print(band + ", ");
pband = band;
line = br.readLine();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (br != null) {
try {
br.close();
} catch (IOException e) {
e.printStackTrace();
} If not, you might want to explain exactly the structure of a line of your file (or explain how to obtain such a file. I have itunes but in my attempt to export a playlist to a text file, all I got was some kind of a CSV like file) -
