Why they changed the papers isn't my immediate concern but rather what they are doing to "calibrated the printers with our current ICC profiles, so there’s no need for you to do anything on your end" process.
There were four or so papers I measured, all different. One supplied profile. Now there is a newer paper and they are doing what to the printers or profile?
It sounds like they are fudging it - but that's not necessarily bad if all you are after is a perceptual ("looks good") result. The nature of the printing process matches the media relative nature of ICC profiles - they both separate the substrate from the colorant, so any non-absolute intent tends to track in terms of overall tonal and color reproduction with any slight change in substrate color. Any changes in tonal behaviour may be compensated for by a calibration system. Of course there is complete failure of the ICC profile to track absolute color change, so it's not going to work for side by side proofing. Graeme Gill.
