starchild, Astute totally owes you.
And so do I, thanks for clarifying for me. They were insisting that any rasters, etc. had to be CMYK, but your suggestion totally works. And now that I can use it and played around with it for a moment yes, the color temp thing is very handy for doing a quick visual on coverage, which is something that will save me tons of time bouncing files from AI to acrobat to check ink coverage.
And I agree, the ink area data is huge, especially for us discharge printers.
