Im unsure of the deltaE for the press. Xerox does distribute a chart showing acceptable color drift within run, so I understand realistic expectations. I was just trying to think of a way to create a generic profile to emulate the press that I cant actually profile. Is that where the Gracol suggestion comes in? Right now we just switch our renderings between iGen CMYK, SWOP Plus, SWOP Coated, and Commercial CMYK and then make additional adjustments via TRC.
Please understand that our standards for "matching" are pretty low as our customers understand our service to them. I'm talking color differences that are obvious without measuring or magnification. I'm just trying to come up with an adjustment to our current workflow, or an additional setting to try on the press, that will help us match a higher percentage of jobs without manual intervention.
Our digital operator mentioned that all files are converted to CMYK in Prinergy including PMS colors. His thought is that if the color is indeed inaccurate on press, the spot colors would be off anyways.
Right now I use the output preview tool in Acrobat to help me get a feel for the SWOP CMYK makeup of the file I am working with. My next tool in that line of thinking will be a Pantone Digital Chip Book which will allow me to compare the offset sample to the swatch and its digital CMYK equivalents, but again I am still taking up alot of my time, and as our business grows, I will need to simplify the process.
