I'm trying to use CS4's Preflight to make sure that there are no process colors in my 2-color (2 PMS) job. I've set up a preflight profile that specifies that the only color space allowed is Spot Color (so, RGB, CMYK, Lab, and Gray are checked as color modes not allowed). My document has several elements, including text, that use the Paper swatch. Preflight sees Paper as CMYK, so every instance where it is used comes up as an error.
While I know that it's OK to use the Paper swatch in 2-color jobs and it won't cause printing errors, it's annoying that I have to sift through InDesign's list of non-errors where Paper is used correctly to make sure there's not a valid instance of a CMYK error.
I've tried editing the Paper swatch, but it does not give me the option of specifying it as a 0% spot color, only RGB or Lab, Also, I know that I can search and replace Paper for 0% of one of my spot colors, but that seems like a tedious and unnecessary step to have to take when the Paper swatch is supposed to be a valid way to specify no ink.
The last thing I'll mention is that this problem appears to have been introduced in CS4. In CS3, I used to do a manual separations check on 1- or 2-color jobs (I'd print separations with the spot plates turned off to a virtual print queue to see if any pages were sent) and Paper never caused CMYK output. Now, in CS4, the same test sends empty CMYK plates for pages with Paper elements.
Any suggestions or workarounds?
