I have 80+ sheets of Kentmere Fineprint VC FB Neutral Tone Finegrain Semi Matte. I am in a beginning photography class and I'm the only one with semi-matte paper. The teacher isn't too good with outside of the box things, and semi-matte isn't inside his box. Unfortunately, my prints are coming out grey-ish, and I'm having troubles with chemical stains. Teacher says this is because the semi-matte needs a different printing process. Anyone have any experience with this?
