Speedball Diazo Photo Screen Printing Emulsions are used in a two part process that coats the screen in a light sensitive barrier and when properly exposed to a light source, creates the highest detail possible in your screen. They offer a variety of techniques including printing of fine line drawings, various hand and commercial lettering, as well as photographic half-tone positives. These photo emulsions produce effective results when used with water or solvent-based inks and may only be used on polyester screen fabrics.
Diazo Photo Emulsion Remover - Speedball Diazo Photo Emulsion Remover thoroughly cleans screens used in screen printing, allowing you to use the screen again and again. Please note that once you have started removing Photo Emulsion you must not let the screen dry or apply water until completely clean. When the screen is clean and all emulsion has been removed you may then wash the screen out with water. Available in a 32 oz. bottle.
