Can you take your files from input stage to a first refine all at 100%. Then do a second refine and only release the M,K. Then do another second refine from your first refine to a new process template that is scaled at 102%.
We ps or PDF to to an input folder. drop that to 1rst refine template. That puts the new PDF's in a folder called first refine
then we take take those PDF's and do a 2nd refine but we have several second refines.
Second Refine CMYK
Second Refine CMYK Trap
Second Refine Greyscale
All of these automatically put the finished PDF's into a folder called Final PDF's This is what we link our impo software to. You could do the same except from your first refines you would go to
Second Refine 100%
Second Refine 102% and only release the colors needed. Hope it helps
