Silk Screen Printing Blockout

Lawson Red BlockoutScreen printing block out is used to fill any pin holes or other imperfection in the screen emulsion after exposing or curing of the emulsion. Some screen printers refer to it as filler, hole filler, block out, or blockout pens. Tip on use: Let screen dry. Hold screen to a light to see pin holes.
You can apply the blockout with a piece of card board for wide areas, or an artist brush for pin hole filling. (See Pin Hole Solutions, if pin holes are a common problem in your emulsion)
