I'd love to print on the textured stock, esp Hahnemuhle German Etching, if it would hold the ink and I don't have to spray every print I produce.
Having had quite a number of William Turner prints suffer considerable flaking (HP Z3200 inks), I'll never again fail to spray a print on textured matte paper unless it's going behind glass quickly. I'd like to hear if others feel this is unnecessary.
Recently I used Epson Cold Press Natural for a project of 55 A2 sheets. In the scheme of handling several sheets, there was an error on my part that caused several sheets to abrade one another - ink against ink. They had already been sprayed with the Hanhnemühle branded-spray (one coat). I could detect no surface damage, but don't know if the spray made a difference. I do know that William Turner prints would have been ruined in their place had they not been sprayed.
