CCI Ultra-Block Water Soluble Blockout
This product is a high viscosity, water soluble blue blockout designed to fill the open areas of the screen not covered by the emulsion.
I When the screen is dry and free of contaminants, pour ULTRA-BLOCK® on the print side of the screen. Spread over the open areas of the screen until completely filled.
II Touch up all defects, including heavy blobs which tend to dry on the outside and pop off or smear during printing. Where very fine meshes are used, you may reduce the viscosity by adding a little water.
III Remove blockout with water.
