Did a quick search and didn't find an answer, and the Epson manual really isn't much help. When exactly should I invoke the thick paper setting on my R1800? The Epson manual mentions a few Epson papers, but does not specify a weight above which I should activate the setting. Or if it does, I missed it.
I plan on using papers like Hahnemüle's Bright White Photo Rag and William Turner, both 310gsm, and maybe some Museum Etching (350gsm.)
Also, any suggestions for a heavier glossy paper, since this printer makes really nice glossies. I ran a couple tests using some Ilford Galerie and they look great.
