A waterbased medium used in silk screen printing. Acrylic paints can be mixed with Derivan Printing Gel to keep the colours from drying and clogging the screen mesh, thereby allowing more prints to be made at one time without having to clean the mesh between every print. Printing Gel can also be used to reduce colour strength when transparent colours are required for printing. Mix the Printing Gel into the colour until the desired transparency is reached. Also suitable for screen printing on paper or board.
