Thanks for the information. It is a bit too technical for me. I can read what you are saying and understand each sentence, I think, but I can't put it all together into an executable action.
At this point, I'll try a second coat of overgloss, or the spray. If that doesn't work, I'll try a different paper or move back to the Epson all gray inks which I use for printing negatives. I'm less inclined to drive into piezographic tools or custom profiling since IJM does not seem to have any experience with my specific paper Harman Gloss Baryta.
Cheers,
John
