Photoshop :: Print Channel In Color
Nov 10, 2006
Color pencil is a transparent medium, most like watercolors; as a result, it is equivalent to the CYMK mode in Photoshop.
I'm working on an exercise to use only the primary colors in color pencil. If I am in CYMK mode in Photoshop, I can separate each channel to see how much pigment goes into each color. However, I would like to print it on a transparency IN COLOR, so I can superpose them onto each other to see each contribution in its original color.
But whenever I have only one channel left - say, magenta - the image appears in grayscale.
Is there a way to have each channel show up only in its own color, rather than in grayscale?

I need to print a document with partial UV-spots, and cannot figure out how to make my Illustrator document ready for print!
The online print center guides me to: create a 'seperate print channel' for the specific elements in my document i want covered, with either a '5th color or a special color' set for 'over-print and 100% color'.

I have just lost proper color in my CS5 suite and it appears that I dropped a channel (red?). I did not change my profile and trying to do so has no effect.
Color is correct in all other programs and my monitor is correctly calibrated using Huey Pro. Attached is a screen shot of a side by side of the same image displayed in IrfanView and in Photoshop.

How to make a Spot Color Channel on Photoshop? I am using this image as an example. The blue color in the background needs to be printed mostly with a spot color that is close to the original painting color (ex: Pantone Blue 072C) . But the CMYK color still should be present in within the blues to resemble the subtle nuances of the brush strokes. I can’t figure it out on my own.
For more samples of painting images, go to

The reason I am doing this is because the artist’s works were represented on many publications over the years from many different countries. And we found out that CMYK color alone cannot duplicate the blue color very well (I mean the blue only, no problem with other colors). I know, it is hard to believe, but if you see all the publications and compare it to the original art, you would see the huge difference in color saturation and luminosity. That is the reason, I think it is necessary to use a spot blue for an upcoming catalog of the artist.

I accidentally had my files marked at 16 bits/channel, went ahead and saved them as jpegs. Got a software prompt prior to saving that said "File must be saved as a copy with this selection." I did not know what it meant. I went ahead with the save. Now I am realizing my mistake because I have tried printing my images at a lab and the colors are WAY off. Very gray and horrible. I have my master files saved as psd files as well and have opened those, changed the bits/channel to 8, tried to print and the colors are still awful. I have many files that were saved this way. There has to be some kind of a fix without me having to re-edit dozens and dozens of photos.

For a long time I have been struggling to find a good workflow for what I would call "multi channel color separation". What I want is to reduce a full color RGB image into an image with only a limited number (e.g. 5-8) well-chosen colors, for instance to use as set of masks for screen print. (I'd also like to use this as an effect in itself, mimicking a typical 'screen print' or 'litho' effect on an inkjet print)
The idea is to create a set of monochrome layers or spot color channels. Colors are to be selected by myself (so not necessarily RGB or CMYK). Each channel/layer has to be a continuous tone that I transform myself into a dedicated half tone screen (e.g. with the Andromeda screen filter).
Till sofar it is clear to me. My issue is: How to separate the image in the predefined set of colors?
I can not just select a color range: I can adjust a "tolerance" but that is too general. I need the pixels of with a specific hue but with the full range of lightness (e.g. all the purple pixels that range from dark/medium purple to very light purple). The dark colors can be made dark with a black channel. I'm not sure how to deal with the saturation range.
An approach that gives sometimes a result that is to some extent acceptable is to transfer from RGB mode to an Indexed Color mode and use a custom palette. However, this does not give much control on the halftone screening process.
I envision for instance an approach of filling a layer with a solid given color, select in one way or another only those parts that correspond to the original image and subtract that layer somehow from the image. This process is then to be repeated for each color. Up till now I have not been able to figure the right options to do this. But maybe there is a better way to do it.
One final wish: it would be great if the process can take into account that some layers in the final print are (semi-)transparent. In my opinion this would exclude just selecting a color and deleting de pixels.

I creat an alpha channel it shows up as white on my Photoshop Version 6 while my friend's alpha channel comes up in black on Photoshop CS. Obviously each is a default setting. How do you change the alpha channel color from white to black and vice versa.

I've got a cmyk image with nothing in the black or the cyan channels.
All I was wanting to do is make the yellow channel black and the magenta channel brown.
So, the yellow channel prints in black and the magenta channel prints in brown.

I'm using the 3D render engine vray, using its multimatte render element which assigns mattes of certain materials (or objects) in the scene to a channel: R, G, or B.
I'm curious about the best way to composite once I have this file rendered out. The simplest way I can think of is doing a color range selection on the matte channel's solid color, then using that selection to modify my image as necessary. But I have used After Effects to do this also, and there is a "channel select" effect that extracts the channel and converts it to an alpha mask in one step... makes me think there's a more elegant way in Photoshop as well.

When I save an OIL PAINT file created in Photoshop CS6, it saves with red and blue shapes over the image. Before saving, the image looks fine. I'm running windows 8. Is it me or a CS6 bug?

I'm working in the multi-channel format, which as you may know, does not support layers.
Does anyone have any tips on experimenting with the layout, without the use of layers?
At the moment, I've been working out the layout in another (layer-supporting) colour mode, and then recreating that layout in the multi-channl mode.
Surely there is a better way of testing different layouts, within the multi-channel mode itself? I'm finding it very inflexible at the moment.

This question is more theoretical, as I have found a work around. On a layer, I have a gray color, which I sample, and it becomes the desired Foreground color.
I would like to Fill a Selection in an Alpha Channel with this gray color.
However, when I view the Alpha channel, my forground color is lost to black/white, which I understand, as the Alpha channel is a gray scale image.
But, I am able to sample a gray Swatch to make a Foreground color, but how can I preserve my chosen Foreground gray selected from a Layer? The only way that I know would be to make a new Swatch, and then use that when I am in Channels.

I am a screen printer and I print my separations from Photoshop. I routinely work with multi channel files or RGB files with additional spot color channels. I have created actions to place my registration marks, re-size images, etc to get ready to print but I manually have to create the text labels for each screen if they are missing from the original artwork.
The files I work with have channels named as "Base White, Red, Green, 284 Blue" etc indicating the ink color. What i would like to be able to do is click an action that would copy the text from the channel name and insert it into a separate or each/all channels near the top of the file so that when I print each positive it has a corresponding label for ink color.
I am not sure if this is even possible, and I am limited on my knowledge when it comes to actions and have pretty much got lucky in the past getting them to do what I want without unnecessary steps.
On my registration target action it creates a new channel with each individual reg mark then combines them into one separate channel in which I just copy the contents and select all the ink channels and fill with black to make them appear, i'm happy with the steps it takes as it isn't too much trouble and if this could do the same with labels I would be happy with that.

I wonder if there's a support for 30 bit color-capable displays (with compatible graphics card and driver, of course...) in Lightroom 4...
I have a NEC PA241W monitor and FirePro 5800 graphics card at my workplace --> which work well with 30 Bit color depth in Adobe PS CS5.0.4.
Since Lightroom 4 requires an "OpenGL 2.0" compatible graphics card it's obvious, that OpenGL is used now (I think LR3 didn't..?). If LR4 is able to handle 30(48) bit color depth(?)

Is paint.net v4.0 still promising color and alpha channel editing / masking?
I'm sure I read this in the roadmap feature list years ago, though I can't find the place to reference it. In fact this is my favorite anticipated feature for which I've been checking paint.net every month for the last five years!
I eagerly downloaded the 4.0alpha but see no sign of color channels to go with layers

I'm experimenting with a digital IR camera. The images are very "magenta" in color and everyone states to simply "swap the Red and Blue" color channels. How can this be done in Paint.net? Is there a plugin that would process IR color pictures?

I was wondering what is the best way to save a photoshop file such as a business card or stationary labels so they "KEEP" their color you see on screen.
I am already building in CMYK mode. My Client has a nice gray scale scheme but I am worried that the print shop will mess up the colors.
How do I create a custom set of colors and adhere to that scheme throughout the clients stationary and media.
ie. Cards, Labels, Signs, etc.
Is there an option to print a color scale along with the image, sorta like when you calibrate your printer?

I'm having an issue with Autocad LT 2010 where when I xref in my title block which has our company logo in color, the logo will only print in black and white. If i open just the title block and print it, it will then print in color. I only seem to have this problem when the title block is xref'd in. I downloaded the 2012 demo version of AutoCadLT and it prints just fine?This has just started happening when my computer was upgraded to Windows 7 64 bit.

What I want to do is to have an adjustment layer that is a reversed, black and white image. I initially thought to merge B&W and reverse adjustment layers, but read that an adjustment layer may not be the target of a merge. Is the way to accomplish this to fiddle with the B&W adjustment layer sliders somehow?
I like how the black and white displayed image of a given color channel looks, how can I export that channel into a layer?

My printer told me to add 5% C 5% M and 5%Y to my 100%k channels as without it I can see the black comes out a little/touch fury on things like small thin text.
Is this the same on all other colors too? Eg. say 100% Cyan color, should I add 5% M, Y and K?

I upgraded from CS5 on XP to CS6 hosted on Windows 7, 64 bit. Images loaded into my new CS6 system from my camera or the web display and print perfectly. I am using the same printer for CS6 as I did for CS5, an Epson 3800.
However, when I open and print older CS5 generated images using CS6, the images print with what appears to be reversed grey tones and off color but the monitor displayed colors appear just as good as they did on CS5. In summary, images generated in CS6 print ok, but images generated under my old CS5 system print with off colors using CS6 but display ok.

I was getting great photo prints from my Epson 870 = colors matched what I expected well enough to satisfy me (it doesn't take much! )
But recently, everything I print FROM PHOTOSHOP has a pinkish cast. I wish I could say "I've only changed one thing" between "when it was good" and "now it isn't" but there is too much water under the bridge for that. I CAN tell you that I installed Epson's "PIM II" system trying to solve an unrelated problem, realized it didn't solve it, and de-installed it. I believe the problems happened after that - but even if I could point the finger at it, I'm not sure I'd know what to do.
I've been trying to eliminate variables, so I gave up on photographs I simply wanted to print, and created an image from scratch I want to use anyway. (I plan to use it when I shoot photos to confirm exposures, set white balance, etc.) This document was created in 8-bit RGB and assigned the "working space" profile, which I have set to sRGB IEC61966-2.1. This is the same profile I have been using, that I have assigned to my photos, etc - - and prefer not to screw with because it has worked for me in the past. The document has some grays I created using R=G=B, and a range of colors including pure R, G and B. You'll see in a moment.
Now - when I print this doc from PS, it gets a very pinkish cast - especially in the black-to-white gray bars. However, they look fine on the screen, and I verified their pixel values with Apple's "digital color meter" app. My monitor, by the way, is an Apple Studio Monitor, and the system is set up to use the Apple Studio Monitor profile as the colorsync profile for the monitor.
But here's the kicker. When I open and print this same document using Apple's "Preview" app, and the same print settings - it prints properly!. I conclude from this that the problem is somewhere with PS, not with the printer or other system settings.
This image (about 200K, jpeg'd, but not enough to not make the point) is a screen shot showing the same doc open in PS and Preview, along with my PS color settings dialog. I DO see a slight color difference in the way PS displays the file (particularly the blue square) - but the difference in printouts is considerably more severe.

EVery time I print a test target for color profiling, I open CS4 so that I can print with no color management. I can't figure out how to do it in CS6. I must be missing something obvious, but I just can't find the option to print without color management anywhere in the CS6 driver.

I have CS6, Epson 3880 printer. Both monitor and printer have been calibrated. When viewing a pic that I wish to print, I go to view, proof setup and chose printer and paper, preserved RGB box is check. This gives me a proof, which is very accurate to what is actually printed. Here's my problem: There is a color change when viewing the pic in proof print mode, which is what in fact, gets printed. Most of the color change involves alteration in red. A red bowl is changed to a brownish read bowl for example. I have been unsuccessful in trying to match the proof to the original color scheme. I've played with hue, color mixing, all to no avail. Is there an easy way to match colors original pic and proof/print?

I have been trying to print a target from i1Profiler so I can read it with my i1Pro and create a printer profile, but no matter what I do, there is no way to get photoshop from supplying a profile while printing. I tried to select Printer handles color and then put the printer driver in COLOR MANAGEMENT OFF (seemed to me this would disable both the printer managing color and photosbop managing color). Tried printing this way ( and many other ways) but NO SOLUTION --- the prints are EXTREMELY different from the on-screen view (which is in a properly profiled Apple monitor) and they actually look like the ones with a profile chosen.
I also tried the utility Adobe Color Printer Utility and same results!!
I am using an EPSON Stylus Pro 7900 that I just purchased.
