Forgive me for the ridiculous question but I never went to art school and I slept through my physics of light class... I have been running a print shop for about 6 months, doing gig posters and art prints for local folks, as well as some CD covers, business cards, etc... I have recently been commissioned to print a set of 18x24s that will be cut into over 7000 4x6 art prints.
I have a nice film printer, exposure unit, big supply of screens, great manual press, and my process for pre-press and printing is solid. My tools and skills are incredibly legit and the end product shows it. However, this commission is going to be a bit tricky for me as it is very important that my the colors and overlay are done exactly to the artist's request (whereas I have been eyeballing it up to now).
I have been mixing acrylics with Speedball and don't really want to jump into house paint quite yet. Short of buying a $600 mixing kit, is there some way of at least getting me close to the right mix? Mix different quantities of CMY inks or RGB inks?
