Using Blockout is an important step in preparing a screen for press, but fixing small pin holes in your emulsion after exposure or even during the printing process is difficult to do with a regular liquid blockout. Using a blockout pen allows you to quickly and easily block out small pin holes or registration marks left in the emulsion. Don't worry about other blockout solutions, simply apply this pen and the pin hole goes away! Our green blockout pen is ultra fast drying (30 to 90 seconds) and water soluble. We recommended this blockout pen for plastisol, UV and most solvent based inks. Reclaims with warm tap water.
NOTE: Blockout pens must ship via UPS Ground*To ensure complete coverage, the blockout solution in these pens has a fairly high viscosity. They need to be shaken well before use and may have to be squeezed hard to get the block out fluid moving smoothly.

Hi Chris! Thanks for leaving this review of our Blockout pen, I am glad it suits your needs! Matt C
I'm a hobby printer and used to have to precisely cut out tape to patch my pinholes, but this makes it so much easier. I thought the emulsion would dry out over the cap of the pen, but it has not yet over numerous uses. Saves my screens and tape so I don't have to create another screen or use extra tape. Perfect product!
