2 Color Gradient Question

I am working with our logo to be used on an envelope. It has a gradient in it that goes from Reflex Blue to Black.
I'd like this to be a 2 color gradient but the problem is the transition from a spot color to a spot color makes for some real muddy colors in between. Going from process to process blends nicely but then it becomes a 4 color job.
Does anyone have any pointers on getting a nice gradient with 2 spot colors? Thanks much.

Robert,
Reflex Blue cannot be shown correctly by standard monitors.
That's one problem. The other is, that a gradient from blue
to black is looking anyway rather ugly (IMO, of course).
I've tried some remedies:
1) Replace Reflex Blue by a a color more towards Cyan.
2) Use tints of Reflex Blue and Black. A tint is a
less dense color, which can be created by rasterizing.
See help texts. This would still require only two spots.
3) Insert a tint of a spot as a halfway gradient color
(drag any swatch to the gradient midpoint).
All this would work technically, but esthetically I can't
see an improvement (except 1, perhaps).
My opinion (OT): a gradient from Blue to paper white is
more convincing.

Color gradient in a non linear geomerty

Hi all,
I try to got an color gradient from the outer side to the inner side of this geometry
the problem : The bandwidth of the gradient should be more or less the same in all areas of the green geometry(means the whole spectrum of the colors)
And the gradient has to go perpendicular from the outer to the inner side.
I ask a similar question already some weeks ago but this looks at least for me different
Could anyone help me with this problem ?
Thx in advance
Mark

Mylenium,
thank you for the answer. But unforunately I'm a newby. Could you go into more details please ?
Mark
PS:
The problem I always got with the gradient tool is the following
The gradient starts at a certain point and uses a hard coded distance (e.g. 50 pixels from this point to this direction like a vector)
This makes it impossible to change the geometry with the full gradient
For example :Filling this rectangle with a gradient and I’m defining a vector mask to it
Afterwards I changed the vector mask to this
The gradient is cut instead of changing, compressing it.
Is there no way to define a starting point (edge, path), a direction and a target edge, path ?
Because then, after changing one of the edges, the gradient has to be recalculated.

Weird and unwanted color gradient after Photomerge

Hi all,
I got an annoying problem with a weird color gradient that appears where it shouldn't. My context is, that I'm producing underwater photomosaics. I use Photomerge for merging, which works great for the often uniform seabed sediment images.
[merge1.jpg]
The example is 65 images, btw. After placing the images manually within Photomerge, all looks great and ready for a perfect result after rendering (see above). However, when doing so, the final merge from within Photomerge (by clicking the OK button) creates perfect smooth blending, but a weird color gradient crossing the whole mosaic. this might originate in the fact, that the individual images also are not perfect, due to the uneven lighting situation underwater. In case all images are a bit reddish at the top and yellowish at the bottom, the final gradient over the full mosaic shows that as well. So to me it looks as if Photoshop just tries to be too smart and thinks, reapplying that pattern to the whole would be a great thing to do, which it isn't of course.
[merge2.jpg]
I discussed this "bug" with (indeed very helpfull) Adobe staff and they recommended, to create the merge with the "Blend Images Together" option in the "Load" dialog unchecked. This creates a mult-layer document after rendering, with the images being placed properly but not blended.
[merge3.jpg]
From here on, Adobe staff recommended, I shall use the "Auto Blend Layers" function (File menu), but the result is identical as image 2. Ok, then, they recommended, to uncheck "Seemless Tones and Colors" in the "Auto Blend Layers" dialog. Indeed, this gets rid of the gradient, ...
[merge4.jpg]
... but shows very hard edges of the images, which get very prominent after optimizing levels:
[merge5.jpg]
Was that understandable? Would anyone have experienced (and solved) the same issue? Or would anyone have an idea, how this could be handled in a way, that my resulting mosaic looks as perfect with respect to the original colors as in the initial merge window before rendering it (image 1)? Maybe it's a specific Color Setting (Edit menu)? I tried a lot so far but nothing helped and I might not have tried the right thing.
The problem appears, btw, in CS3 to CS6!
Any help appreciated, more information on request! Many thanks,
g

H there,
@TLL: you're right with what you said about the subjective element. Getting spoiled is easy, but staying ambitious is good as well. I do these mosaics since 2003, when Photomerge was part of Elements only. Then, in the first years with CS and CS2, I never had this bug with the color gradient being applied to the final merge. This started with, I guess, CS3 and I think it's due to enhancements Adobe made to the programm (making it more "intelligent"). Unfortunately, sometimes enhancements have dark sides and cause unexpected issues elsewhere. And since we are a minority (making large merges), these do not get fixed, since the majority, stitching what, 20 image panoramas of their home and garden do not suffer. Their images have strong contours and contrasts and the issue gets effective only on uniform images like underwater sediment or, in your case, landscapes shot from above. Going back to CS or CS2 is no option, since only the newer versions give me the processing power I need, also is the blending much smoother.
I played around with gradient masks but I haven't got the right touch yet. Even if I get rid of the color differences, there will always be a brightness gradient, since borders of the images are always darker. And then, the weird gradient is a bright / dark one, not a red / yellow one. Not much better. Also, each batch job has to work for thousands of images, so has to be a compromise. I just cannot spend more than a day for a 1000 image mosaic, or a week for 6000 images, time is money on a ship (and elsewhere).
I just think the solution would be, splitting the "Seemless tones and colors" function up into "Seemless Blending" (doing soft blending but not changing the colors) and "Seemless Color Transitions" (just dealing with the colors). And making both optional by check boxes...
So far,
g

Color gradients not displaying correctly

I'm having an issue with my color gradients in type and objects not displaying correctly in the content viewer. For the last app I created, I made sure the colors were RGB and that seemed to fix it. With the current app I'm working on, that dosen't seem to fix the issue. Actually, when I test in the viewer on my iPad, it shows the correct gradient in the split second that it's loading the update but then once it's loaded, it goes to a gray white gradient (the correct gradient is from a yellow to a gray; attached a pict for referrence).
Anyone know why this is happening? Thanks in advance!
UPDATE: It seems to view fine if I preview the page via the foilo overlay but when I preview the folio, that's when it's no viewing correctly.

The Color Picker is unreliable for choosing colors based on what you see because it is not color managed while Color panel and Swatches are.
In your image, the color that you see in the Color Picker is how your monitor displays R=0 G=255 B=0. The color that you see in the Color Panel represents the same values in the file but the color management sends different values to the video card and thus to the monitor to display a color with appearance in the color space selected for the document. In your image this is a CMYK color space which you can check from the Show popup menu at the bottom left of the document window. To check the different values the video card is using, make a screen capture, save the image, open it in Illustrator and measure the color with the eyedropper. The color translation from the values in the file to the video card allows simulation of color spaces other than your monitor's. This simulation is accurate if you have a monitor profile installed in your system that correctly describes how your monitor displays colors. Such profile is created by using a color measuring device and profiling software. If your monitor profile (color space) installed in the system is the same as the color space of the document then there will be no translation (simulation) which in effects shuts down the color management - then the colors in the Color Picker will be the same as in the document. Many people do not bother to get an accurate profile of their monitor and use a generic sRGB profile for that. In such case working in RGB color mode using the sRGB color space (default in the Color Settings) will give the same colors in the Color Picker and the document. This usually is a sign of using a monitor that incorrectly displays colors.

Un-smooth color gradient

I'm a new mac user, and had used the macbook pro 2.4G with LED backlight for one more month. I find the color gradient is not smooth in second primary color to primary color. Please check the PNG files as bellow links.

In those patterns you will find many vertical lines. Those will make you see some photos with contour or noise by Macbook Pro. I have double check many other PC notebooks. They don't have this issue. It is hard to believe the high-end notebook has such kind of color performance. The color performance is too poor to use the "Pro" title. I feel so disappointed to spend a huge amount of money on the Macbook pro( Poor?).

SampleImage() in 4-color gradient issue

hi there
I am trying a technique for logo/element removal that I saw in a post from a couple years back, where a tracked, solid "patch" is placed over the unwanted element, and a 4 color gradient effect is applied to the patch, which then uses the sampleImage() method to grab local colors around the element.
I've gotten it working fine with the below code, except for one problem: when I parent my null (acting as a "color picker" position) to the original tracking info, the color no longer samples properly. Unparenting the null makes the sampling work fine, but then, I have to hand key the null, which is a pain and doesn't produce great results.
myPoint = thisComp.layer("Null 1").transform.position;
target = thisComp.layer("myAwesomeFootage.avi")
target.sampleImage(target.fromWorld(myPoint), radius = [1, 1], postEffect = true, t = time)
Any tips on getting around this parenting problem?
thanks!
ML

You need to add an extra toWorld() layer space transform to convert the layer coordinates to comp/ world coordinates.

Problem with InDesign color gradient swatches

I've recently upgraded to CS5 and I can't seem to create color gradient swatches in InDesign. When I go to create a new gradient swatch in the swatches palette, it will only let me do black and white - as you can see in the pic, I can't select the stop color.
I'm sure it's something simple that I'm missing, but any help anyone can offer would be greatly appreciated.
Thanks!

Lightroom color cast question of JPEG image

Lightroom color cast question of JPEG image
Camera Canon MKII Color Matrix Adobe RGB
Photoshop CS Color Setting Adobe RGB (1998)
Lightroom 1.2 as new lightroom user I did not think that I needed to choose a color setting or color profile until I am ready to print my photos. I have not done any preset camera calibration.
Link to my website with example photo http://www.basecampphotos.com/color.jpg
My question is why is Lightroom displaying the images with a yellow color cast ? The image is a print screen from Lightroom on the left and Photoshop on the right The color cast problem can be seen in the white walls of the stairway. Also when viewing the image with Windows Picture and Fax viewer the walls are white as expected.
Any ideas or suggestions as to why Lightroom is displaying the images with the yellow color cast or what I need to do to correct the issue ?
Thanks
Jim

Almost definitely a corrupt monitor profile. Time and again this turns out to be the cause of such differences between PS and LR. You need to recalibrate the monitor or if you do not have a hardware calibrator, delete the profile from windows' monitor properties pane to test and then get a hardware calibrator.
P.S since you are using adobeRGB jpegs, Windows picture and Fax viewers cannot give you the correct colors even on a calibrated monitor. Those are not color managed programs (I believe picture viewer finally is in Vista but definitely not in XP which you appear to be using). Also, PS has to be correctly set up to always preserve embedded profiles and to ask when you have profile mismatches, otherwise even PS will give incorrect color. Make sure to set this up in Edit>Color settings.
P.S.2: Make sure you are not applying defaults in Lightroom to your images either on import or elsewhere. Sometimes people by accident define develop defaults that in this case might contain a white balance shift. Go to LR preferences and open the Presets tab. Here click on "Reset all default Develop settings" and make sure that only the auto grayscale checkbox is ticked. For images that it might have already happened to, make sure to hit the reset button.

Photoshop CS5 color gradient in a non straight area

Hi All,
I'm a newbe and I have the following problem in Photoshop
I want to fill the white area with the blue to yellow color gradient. This has to be in a way that the gradient goes perpenicular form the outer side to the inner side (not top to down or left to right) How can I achieve that ?? Can anyone help me on that ??
Thanks in advance
Mark

Hello c.pfaffenbichler,
first thx. for ur helpfull answer it's nearly solving my problem but maybe I did something wrong.....
By the way it sounds german ur name may we can talk in german ?
Here is what I got after I did the following
1. I Selcted the area of interest
2. generated a new layer of the selected area by pressing STRG + J
3. then I applied the layer style but I got this...
The gradient will be appiled 2 times. One form the outside to the inside and then from the inside to the outside
May I need some additional steps in between

Another color management question

Hi folks,
Apologies for yet another color management question, but Im getting very confused and could do with some help. I use a Canon 10D and Canon 30D. Ive come to LightRoom from Pixmantec Raw Shooter.
As Ive gotten more serious about producing high quality images for both the web and as prints, I thought Id invest in the Colorvision Spyder2 calibration product. So my monitor is now calibrated (quite a difference from what I was seeing!) and I have a calibration profile applied.
My needs are pretty obvious I want my images to look the same wherever theyre viewed including exported files (such as JPEGs) whether this be on my monitor (in LightRoom, a web browser, Paint Shop Pro, whatever) and on a printer.
Perhaps Im getting confused because Im trying to compare what LightRoom does with what RawShooter does.
In RawShooter, when exporting from RAW to JPEG, I can specify the RGB Working Space Im using and then select my monitor profile. I think that what happens is that the export mechanism takes this profile into account and, low and behold, the JPEG looks fine when viewed in any web browser - the colours are exactly the same as in RawShooter. In Paint Shop Pro they look fine too unless I enable Color Management in which case (Im guessing) the monitor profile is, essentially, applied twice! But the upshot is I seem to get the results I want.
What I cant figure out is how I do this in LightRoom. I can make the same adjustments to the RAW image as I did in RawShooter, but there doesnt seem an option for me to select my profile on export to JPEG only the standard 3 color spaces. Anyway the result is a JPEG that looks somewhat different when viewed in a web browser, or Paint Shop Pro with Color Management turned off. However, if I turn Color Management on in Paint Shop Pro, then it looks fine. So Im assuming that my profile isnt accounted for when exporting JPEGs from LightRoom.
So any pointers or explanations would be really appreciated. I also acknowledge that this is my first foray into color management, and feel free to tell me to go and read some introductory article (link please!) and then come back with a sensible question if thats whats needed!
Thanks in advance.

Lightroom color management.
a.) Monitor profile used: The profile set as the default in your operating system (e.g. Windows xp). (your monitor profile software usually does this when you calibrate/profile your monitor).
b.) Working space: ProPhotoRGB
c.) Export color space: You can choose one of the following sRGB; Adobe RGB or Pro Photo RGB.
There is no option (afaik) to change a.) or b.) the option you choose in c.) will affect how the exported image will be displayed in color managed applications or non-color managed applications.
Non-color managed applications are not able to display Adobe RGB or Pro Photo RGB correctly. I guess if you wish a consistent display of your images in color managed and non-color managed applications then the only common factor is sRGB and you should export your images in sRGB color space.
The benefits of the other expanded color spaces are in printing and you also would have to get this end of your color management correct. Printing profiles to match your printer and each paper being used etc.
Until you can get this all sorted out you will get better results from sRGB, this is also applicable when using most commercial printing services.

How do I make a two color gradient?

I've been trying to create a two color gradient and I cannot find how to do so.

Make sure you have two SPOT swatches available, or else your gradient will contain 4 process colors. If you only want the two colors in the file, make sure you choose those colors in the gradient panel (in pull-down menu, choose swatches). Then your gradient will use only those two spot colors. Hope this helps.
Cheers!

Color Gradient on External Display using a Macbook

I noticed that a gradient created in Photoshop on my 13" Macbook looks too sharp(not a gradual blend) and I can see some "banding" between the colors. There is nothing wrong with the laptop but my question is would the gradient look more professional on an external apple cinema display hooked up to my Macbook? Or is the fact that I don't have a dedicated video card in my Macbook mean that the gradient would likely appear poorly on my Cinema Display as well?

First:
The lack of a discrete video card on the MacBook has absolutely NO impact on gradients in Photoshop. In fact, except for rendering some of the filters in that application, a discrete graphics card has no benefit in Photoshop.
Secondly:
How familiar are you with Photoshop? The overwhelmingly likely cause of your problem is that the gradient is done incorrectly. (For example, if you try to apply a gradient to a low-resolution image, you'll get banding. Make sure your image resolution is 300ppi.) I use Photoshop on my MacBook all the time with a variety of gradients and I've never had this problem. I also have a 23" Cinema Display that I use with the MacBook -- gradients appear exactly the same on both displays.

2-color Gradient - Separations

Hi, all. I'm back with more silly questions about gradients for offset printing. I'm working with a logo that features yellow streaks that fade into the solid blue shape over which they are superimposed, like so ...
At some point, I'll need to produce separations for offset printing. What's the best way to set up those yellow streaks for this purpose? I'm courting the following options, but I'm not really sure of the correct approach.
1 - streaks as solid yellow lines fading from 100% to 0% opacity laid over solid blue
2 - streaks as yellow to blue gradient over solid blue
3 - streaks as solid yellow lines with a blue gradient (100% - 0% opacity) overprinted to create the fade. I suspect this will produce some green, but not sure.
4 - streaks as solid yellow lines fading to transparency using an opacity mask then laid over the solid blue
So there you have it. Currently, I'm using method 1 and the colors seem to separate but I wonder if there won't be a faded out area in the middle where neither ink is at 100%. Can anyone give me some advice about how best to execute this graphic in ink on an offset press without creating a green tint in the streaks? Any insight would be helpful.
Thanks!
P.S. I'm using Adobe CS6

To help out the middle from looking faded and weak in the middle, you can stack a yellow gradient on top of a blue gradientand set to multiply, then move the triangle from 50% towards 30%. Thisi will help no matter if you are printng 4/c, spot, white ink or substrate.
