I am new to screen printing and have a few questions. I have heard that photo emulsion is white glue with a dye. It was also said that the sensitizer is potassium dichromate watered down. Anybody here make there own? If so any tips?

Yes, the basic components of direct emulsion are very similar to poly-resin glues like Elmer's. Yes, all emulsions are basicly the same, but that's like saying that all cakes or hamburgers are the same.

Potassium dichromate and bichromate sensitizers are carcinogenic and have been almost universally replaced by diazo sensitizer in the 1980's.

They are environmentally harmful and have a short 4 hour to 48 hour shelf life.

Buy your emulsion from a commercial supplier and spend your time printing shirts to make money. You will never make money - saving money - by making your own emulsion.

Standard Screen Supply in NYC still makes bichromate emulsion

Photo Emulsions - Bichromate Emulsions
