I'm a research scientist and I need a very black, very matte, very nonreflective background for some microscopy work that I do (I do microdissections of animal tissue). Right now I'm using the back of my mousepad. I also tried using the cardboardy material from a black binder, but surprisingly it's really shiny under bright light. Also tried printing a solid black sheet of paper from a laser printer, but it looks like crap, and it's not very black at all. Can any of you think of anything else that might work?
