What is the best type of emulsion to use for discharge printing?


I use a pure diazo emulsion for water-based and discharge work. It has longer exposure times, but exhibits excellent water resistance once exposed and dried.

In the past, I used an SBQ pure polymer emulsion with added diazo. This exposes a bit faster, but I found that we could hold finer detail with a pure diazo version. There are also emulsions made specifically for discharge and water-based printing.
