I started this discussion on the QTR & B&W forums, so I won’t go over all that discussion but just give the results of that discussion.
I made a profile for printing on Harman Gloss Baryta and without the gloss over there was noticeable bronzing. I applied two passes of GO30000 and the bronzing was still present. I printed again and used Hahnemuhle protective spray. This did eliminate the bronzing. However, using the spray is not a good solution for our open lab environment.
I am printing on an Epson Quad3800K7 with a neutral inkset and I recently installed the PKHD ink in the PK position. There seems to be a issue with this combination that makes it difficult to make a profile for which the Gloss Over will eliminate any bronzing.
Walker requested that I try the Master profile, but I was not able to linearize it. I’m hoping there is a solution to use this inkset and the Gloss Over without any bronzing.
I should also point out this paper was apparently bought by Hahnemuhle and now called Hahnemuhle Photo Gloss Baryta.
