For a few years, I made carbon pigment prints on matte paper, then masked off the image area and applied 4-5 very thin sprays of MATTE acrylic.
The MATTE is very important, you are just trying to build a very thin, level base. Don't rush spraying. Each coat should be very light.
Then, I would spray with satin finish acrylic a few times.
I developed this method after seeing many Strands, both silver and gravure, and reading about his preference for a slight luster instead of a dead matt.
There are times when I view these prints and think they are the loveliest prints I've ever made in my 30 years of photography. Warm gravure carbon with a light luster. Superb.
Who waxes Pt/Pd and other alternative processes? If so, which wax?
Thanks!
