The only problem with all three "photocopiers" / printers I tested, at the time, Minolta, Canon and Xerox, was the inability to maintain the calibration over time: as soon as I changed substrate, going from outputting on Fortune Gloss 60 Lbs 13x19 to regular Bond paper Tabloid, the delta Es degraded quite a bit, from 1.85 deltaE to upwards of 3 to 4, and I had to reprofile to get back to 1.85ish.
That is typically why there would be a calibration function. i.e. much quicker to re-calibrate than re-profile. [Our ColorBus RIPs had an off the glass calibration function specifically for this purpose, and used quite successfully for Newspaper proofing. Long gone now of course :-( ] Cheers, Graeme Gill.
