When I build a profile for my papers, should I varnish the target as I usually do with all my prints before reading them? I guess so, but for some mysterious reason I did never do that !!! The varnish reacts with the ink, the paper coating, and maybe even with the paper itself. It mostly improves the blacks as well as the gamut. But it seams to my eyes, that the varnish does also shift the tonality of the print, especially in shadows.
I use Golden MSA varnish (removable, UV protection included) that I apply with a roll. Maybe there is also a tiny hue shift caused by the tint of the varnish in lighter parts. The same could be said of the glass that'll come to cover the print.
So, it didn't occur to me until now, but for best results shouldn't I create a profile from that final result, the varnished and glazed print?
