I printed a test image on RR Polar Matte using no curve and compared it to an older test print with the same paper and ink. The two images are very close. I then tested RR Ultrapro Satin using the curve UT14_gloss_neutral.acv and compared that to an older test print of the same ink, paper and curve. It is warmer. I then printed the test image on RR Polar Matte using the curve UT14_matte_cool. This also matches my older test image. It seems as though the issue is only related to glossy prints and I cannot explain why.
