Colour Space Fogra 39

[Ady N]

When working on an image in PS that is to be printed would you generally work in the RGB space or CMYK (Fogra 39 - coated standard UK to ISO tollerance). I got one sent one to the Epsom proofer the other day and the CMYK conversion boosted the yellow too much. If I would have done the processing in CMYK this would not have happened. I am currently comparing RGB to various CMYK profiles and there is little colour difference between the Fogra 39 and RGB so maybe the guy that sent to print used a strange profile................?

What is the accepted workflow and how do you know what CMYK profile is going to be used at final output and would you expect much variation?

I'd stick to RGB as an output source rather than CMYK. There can be a lot of variables involved when an image goes to press, not at least , the Press, the Ink, and the paper Stock. All of these can affect the colour balance. Plus of course there can also be human intervention at the print stage.

My work that goes to repro goes as simple 8 bit RGB files in either Adobe or sRGB ( depending on the final destination). I've never had any complaints from the client. If in doubt ask how they want the files presented.

Have done a few trials since my post and you do 'lose' some of the colour you see on the monitor but it is fairly negligable - far smaller colour space so stands to reason. The conversion/print I was not happy with I think was a seperate issue (monitor I used) so will stick with RGB. Irrespective of the ISO standards and hard proofs the best way is to personally press pass your work where at all possible.
