Atlas Blue Blockout (Gallon) is a screen printing blockout designed for touching up emulsion and blocking out areas of a screen. It can be used with all types of films and emulsions and applies evenly for convenient screen preparation and touch-ups.
Blue Blockout is quick drying and designed for use when printing with plastisol inks or solvent-based inks. Do not use Blue Blockout with water-based inks.
The gallon size provides a larger supply of Blue Blockout for screen printing shops with regular screen preparation and blockout needs.
