The photo emulsion I use every time

Speedball is a top manufacturer of screen printing (or serigraphie) supplies and they make excellent products. The kit contains photo emulsion, sensitizer paste, emulsion remover and very detailed instructions. This is the kit I buy when I'm teaching because everything is clearly labelled and pre-measured so the students can get started right away. It is widely available and very reasonably priced, as well. I use these products in my own printing but I buy much larger sizes than what is available in the kits - still the same products though.
