We're creating an image for a client that will eventually be printed 4c process, and we have to use some very specific CMYK values. However, since we need to use certain layer effects, we need to work in RGB. I assumed that since the CMYK values we use are within the RGB gamut, there would be no color shift when copying from a CMYK doc and pasting into an RGB doc, but I'm apprently mistaken.
I'm not very familiar with color management, since we don't do any heavy duty color work in house, so this is likely a very rudimentary question: how do I keep colors from shifting when pasting from a CMYK document into an RGB document (which will eventually be converted back to CMYK for print)?
Any help is greatly appreciated. Thanks.
you have two possible issues at work that would explain a change
"out of gamut" color between color modes (the RGB colors don't translate well to CMYK)
you are discarding profile information information when pasting (and not Converting to the destination)...
Are you seeing color shift? Or is it just a 1% change or so in the CMYK percentages?
When Adobe decides to develop device N objects, you will have what you are trying to accomplish. Until then, enjoy your mess. Sorry, but that is just how things are as of now. I wish I had more positive information for you, but CMYK is an ugly step child for Adobe and you are the victom of the lack of care like the rest of us.
