Blockout Pen for Pin Holes

Make fixing pin holes easy with Blockout Pens.

An important step in preparing your screens for print is fixing small pin holes in your emulsion after your exposure. Although Liquid blockout like MC Block works well, Our blockout pens make the job more of a 1 step solution. Quick and easy to use.

1. Shake well
2. Hold your thumb over the hole on the rubber plunger and squeeze 5-10 times to build up pressure in the pen.
3. Uncap the pen and lightly push the pin hole area of your screen with the tip of the blockout pen.
4. Release the pressure after the blockout solution is dispensed and lightly distribute over the pin hole.
5. Allow the solution to dry for 30-90 seconds before using.

Reclaim with warm tap water.

Works well on Plastisol, UV & most solvent based inks.
