when I print on matt paper it is ok . Just when I print on Gloss and high gloss paper. Never tried the cotton paper. Cost too much like about $10 a sheet. 
Do most people for  exhibition  prints use matt or high gloss? I am putting a lot of photos and Bryce images into a show this july. I useing mostly Kodak Ultra Premium photo paper[high gloss 11x17] and Epson suber B 13x19 matt paper, 
Have anyone used the cotton paper before?? If so how did it come out?

what you see is not what you know; it in your face
