I've been using glossy papers (mostly from Canon) and decided I want to try something with a little less shine but I don't want to go to matte. So I've been looking at Canon and Inkpress papers and find that Canon has both a semi-gloss and a satin finish. Inkpress has semi-gloss and lustre.
Can someone possibly categorize the differences between these? Also, Inkpress labels some of their papers as being RC; what's the implication of the paper being resin coated when used in an inkjet printer?
