Alright, I need some help on this one. A customer gave me a roll of rubylith from his (now former) screen shop with some screens, figured I could use them. Only thing, I can't remember how to use rubylith ... it's been about 10 years and I used it twice both on litho's. I'm going to test to see if it's the blockout or the exposure mask tonight (I can work with blockout ... do it with green film all the time). Here is my question. If it's the mask, what side sits against the screen that faces the expose unit (clear or ruby side)? Should I provide a layer of acetate between the rubylith and screen? I know the ruby is light safe, but does ghosting occur? Compared to most HP vinyls, is the pressure less to cut? hmm ... I think that is it ... but my mind is rather caffeine free at the moment. Thanks in advance.
