Photoshop :: Spot Colors Do Not Hold CMYK Values
Dec 19, 2012
When placing a .psd file with a spot channel into illustrator, and then later copying this and pasting back into Photoshop the color shifts.
Original Photoshop spot color channel (0/100/81/16)
Color after pasting back into Photoshop (13/99/88/4)
We are making renders of packaging, so the designs are from illustrator. We correct this by removing the Photoshop spot channel and recreating this as a CMYK layer, but looking to avoid this step as we do many many renders. Even with assign color profile set to none this happens.
Viewing Photoshop channels you can see a difference in values between the linked image and illustrator flat tint.

Using CS6 on a MacBookPro Is there a way to find the closest matching Pantone spot colors to the cmyk colors I've created in Illustrator? I know it's easy in Photoshop using the color picker, but there must be a way to do this in Illustrator.

When I use a Pantone color in CS5 and then convert to process, I get certain values for CMYK. However, when I use that same Pantone color in CS6 and convert to process, I get different values for CMYK.
For example, Pantone 2685C converted to process in the both applications yields:
(CS5) C-96, M-100, Y-0, K-10
(CS6) C-90.73, M-100, Y-30.6, K-16.54

I'm having an issue where I can't convert spot colors to CMYK in the swatches panel. Currently to fix I have to copy elements using the spot colors in to a new blank document, then convert them, then paste back into the original document.
Also if I try to delete the spot color, it doesn't fully delete the swatch.
I'm using Illustrator CC 17.0.0

We would like to experiment mixing a spot colour in a normal CMYK image in order to expand the colour palette. Our problem is the fact that we cannot get Photoshop to show us the actual image once we have added the spot colour.
The spot channel shows as if it is being printed on top of the CMYK colours instead of being mixed with them. This makes it very difficult to judge what adjustments have to be made to the image. Of course, saving the file as a DCS2 and placing it in InDesign shows us what we want, but this is too much jumping back and forth between programmes to be efficient. We are runnnig CS3 on Windows XP Professional.

I have a client who asked for a SPECIFIC shade of blue which happens to be 100,70,0,0. Now I know my screen will never show the exact color, always shows lighter. This part is ok. But I go and change the values on the color picker, and then 10 minutes later when I come back to it, the values changed to 95,65,1,0. Why would this happen, it KEEPS happening and not just one one color, on ALL OF THEM, it just changes the numbers slightly fromw hat I put in.

I have a photo of an object on a black background, and during the editing process the cmyk values of the black background are c=75 m=68 y=67 k=90. As this image is to be placed on a business card, if it is possible to change the values to 100% K or 40% C 100 %.

I have line drawings in a layout that I scanned in. I'd like them to be the same or close to the black cmyk value of the text in the document. I'm not sure how to accomplish this. I tried channel adjustment and replace color,
putting in the specific value I wanted (I read that c50 m40 y40 k100 was a good black for print), but nothing seems to work correctly. I would like to keep some kind of greyscale value (not make everything black), but I want the darkest shade to be that specific cmyk value. How do I do this?

I need to use a spot black on some packaging. The spot black will be used as a vignette on top of a photograph of the product which is done in Photoshop. I have created the packaging in Illustrator and need to import this file but it needs to have the spot colour intact. So far I have created a PSD with a Spot channel which I thought was the answer but Illustrator can't read PSDs with spot channels. I then saved it as an eps but when I import an eps it only shows a white rectangle as opposed to the actual artwork.

I'm working in Photoshop CS 5.5 on a Mac, and I want to apply a specific CMYK color to a selection in an image. I create the color with the values C=0, M=100, Y=100, K=10 and add it to my color swatches. Then I select the section of the image where I want to apply the new color and fill it with the paint bucket. The color fills the section just fine and life is good. But then when I roll over the section with the eyedropper to double-check the CMYK values in the Info window, it shows that they've inexplicably shifted to C=9, M=100, Y=100, K=1.

I have a logo that i wish to conver to pms spot colour as that is what the artwork requirement is, it is currently in CMYK.
I am currently using cs5.
Edit, Edit Colours,Recolour artwork, then i am going to colour books and choosing panatone solid coated.
Now it recolours 80% of the logo but leaves some panels as cmyk. I have come across this on different occasions before.
Is it somthing to do with clipping masks? I hope some Illustrator genius can point me in the right direction.

I have a file from a client that has a table with the color values recorded as CMYK. (e.g. 50, 0, 10, 0)
I'd like to display the colors but I can only figure out how to do it if it's in the 256 color format. Is there a way for me to convert CMYK color values to a 256 color value. I realize the hues/colors won't be perfect, and I'll be happy with colors close to what the original data was using. Maybe there's a way to go from CMYK to RGB, and then to 246?

when I pdf a coreldraw document, no matter which pdf-preset I use, the "Convert spot colours to: CMYK" is greyed out so I can't tick it. I need to pdf a document to send to newspaper print. I have never had a problem like this before using CorelDraw X3.

I want a script that can convert RGB value to CMYK values.
I've seen this thread which explains a script to round up and down:
[URL].....
but is there a script that i can actually define lets say the colour is yellow and in RGB it looks ok because its in RGB mode so you change it to CMYK and you have 6% - 9% cyan and you only want yellow
is there a script out there that i can say
if
cyan = 6%
yellow = 80%
magenta = 0%
black = 0%
then change to
cyan = 0%
yellow = 80&
mangenta = 0%
black = 0%
I don't mind writting the code for each colour that needs to be converted as it would only need defining once but how would i make this script?

I have a customer that does a front and back newsletter in photoshop.
They use 100% black and 100% magenta and save it as a .psd. (They don't have no other layout programs)
How can I put it in an IndesignCS2 or quark document and separate it into 2 colors?

I am struggling to understand why Illustrator is changing the values inside the RGB and CMYK boxes. I am also not sure of the exact relationship between these vaues. Essentially, it appears that if you set the Document Color Mode to RGB, it leaves the RGB values that you type in alone. If you set the Document Color Mode to CMYK, it leaves the CMYK values alone.
But as soon as you change the Color Mode, it automatically modifies the values. So if you were in RGB mode and you set some RGB values, it changes those RGB values when you switch to CMYK mode. And vice versa.
I had thought that the CMYK palette was a subset of the RGB palette. It would make sense to me if it did this when I switched from RGB to CMYK mode, but it doesn't make sense to me why it does this when I switch from CMYK to RGB mode.
The other thing I am confused about is the relationship of the values in the RGB boxes to the values in the CMYK boxes. I would have thought that the relationship between them would be static. Actually, it is not. When I am in CMYK mode and I enter a CMYK value of 90 16 0 0, the RGB values become 0 158 222. But when I switch over to RGB mode, the RGB values of 0 158 222 result in CMYK values of 75 23 0 0.

I made a simple poster using photoshop to make the background and illustrator to make the fonts and some other stuff. In CMYK my black is just 100% K ( in photoshop)
When placing image in illustrator the 100% K (black) changes to different black with C M Y added. But then when I save it as PDF the preview shows black as a bit grey (which is something normal- in print it will be just black). So my question is .. should I change enything just to be able to see a 100% K in illustrator in order to match CMYK values of Photoshop? Or should I leave it this way? I guess if I am getting a "grey" in PDF preview is something good isn'it? because in photoshop when I set to 100%K in my screeen it looks like grey and not total black.

Using CS2, I've created one of those swooshy Macintosh Panther wallpaper images, with various layers of sweeping lines and tinted gradient arcs.
Now I want to create the image using just tints of pantone 519 but I'm unsure of how to work with pantone colours in photoshop. I've pulled up the solid coated pantone library and located the swatch, but how do I specify various tints of this colour?
I've searched the forum and come across spot channels, and have read the photoshop help entry on this, but still can't understand how to do it. From what I've read, I make a selection, then create a spot channel of the colour and set the solidity to 100%. If I want an 80% tint, I just adjust the solidity to 80%. Is this correct, or is the solidity more like transparency than tint?
In addition, how do I create a gradient between these two colours?
Final question - I have an element I want to import from Illustrator that uses the same spot colour. Do I have to deal with this any differently to the normal copy and paste as a smart object?

I have a RGB file with two layers; the first containing black lines and the second containing color. I would like to convert this file into a duotone file where each of these layers is one of the two spot colors.
So far I have been able to get it in duotone (by first converting to grey). However, since the black line layer contains different shades of grey pixels as well (from anti-aliasing), it turns these grey tones into the spot color too.

I'm pretty new to preparing artwork for spot colour printing - it's a hoodie design in this case.
I created the artwork in CMYK originally, and have got some of the way towards converting into a 5 colour print job using Recolor Artwork, so I've got it down to 5 swatches.
However, the printer is asking for colours separated by layers, which makes sense - I think means knocking everything out so there is no overprinting - is this correct?
If so, what is the best approach to take, to avoid unnecessary work, to convert from the current artowrk, with a lot of overlapping artwork, to produce 5 layers each with vector artwork coloured with its own Pantone swatch?

So I've been having this issue with Photoshop ever since I started using it on my Windows machine. On my Mac. I could set something to any color and it would appear that way on the screen in RGB mode. However, when I try and do that with the same exact color on my Windows machine it appears in black. I don't have Gamut Warnings on either. However, when I switch the mode to CMYK the color appears. The problem with this is I use photoshop for GUI's and such, not print materiel so if I have it show in CMYK Mode it will give me an inacurate look at how the colors will look.

I am using PS CS4 and I am in CMYK, proof setup is working CMYK and the color settings I am using is U.S Web Coated (SWOP) v2.
If I slect a color which is 100% black (greyscale) which is 0 C, 0 M, 0 Y, 100 K my color picker comes out at a muddy grey with a touch of red.
Why is this? Otherwise I have selected 100, 100, 100, 100 and this is 100% black for CMYK
Should I not worry about this?
My output is CYMK digital print

In the color picker, if I enter R255-G80-B0, the CMYK color reads M83-Y100. However, if I instead enter the M83-Y100 in CMYK first, then the RBG numbers are R240-G83-B35, and if I enter these numbers first, then the CMYK numbers change again.
Why is this happening? Shouldn't the RBG translate to to just one CMYK color and vis versa?

I've had this problem before, and it randomly popped up again today.
This time restarting Ai fixed the issue the first time. I just don't know if this was human-error/setting on my end, or a minor bug to report.
So I create a CMYK Ai doc. Create some black text and/or shapes. Then decide to change color to rich black by manually entering CMYK values (in this case, 60, 40, 40, 90), select ok. However, the colors revert back to original percentages (75, 68, 67, 90).
In past versions, it's happened once or twice, and restarting Ai didn't solve the first time.

Photoshop 5, (not CS5, but version 5). I was using it on a Windows XP computer, but my new computer, running on Windows 7, would not run Photoshop 5. So, I bought CS6.
There's one problem. I use Photoshop primarily for coloring comics. Which means I create images in CMYK color. And I'm noticing a slight difference in certain colors in this new version. Most noticeably, in a color combo I use for coloring average "Caucasian Flesh".
My settings for this shade would normally be:
C-3
M-25
Y-25
K-0
This, in the old version of Photoshop, would produce a pretty average "beige" color. However, when I use this same color setting in the new version, the shade is noticeable pinker. Strangely, when I open documents in CS6 created in the older version, they retain the old, proper "beige" look. But the same color settiing in a new document produces this "rosey beige" color. (By the way, this isn't a "monitor issue"...... I have printed out the documents, and it's just as apparent in the printed versions.).
I suppose I could just use an altered color setting with less magenta, but I'd like to find out why this is happening, and why I can't use the same color settings I did in the old version of Photoshop.

I have some crosswords that have been exported as CMYK but not just 0 0 0 100, a mixture of colors, something like 2 13 2 100 or whatever. How can I change the black throughout in Photoshop and save?
The printer have of course told me that it needs to be on the one plate.
