Pinholes? No problem. Blue block out pens are perfect for touching up pinholes in the screen room or on press. They are water resistant and reclaimable. They resist water based, plastisol, UV, and most solvent based inks. They are easy to use and super effective for blocking out pinholes. They are quick to dry within 10-15 mins and recommended for use during the screen preparation phase.
