PMI 321 Block Out Tape (3”X 110)
PMI’s 2″ Block Out is a white vinyl that is used for blocking out areas of the screen that are not covered by the emulsion. It can be used on both the inside and the outside of the screen without damaging the emulsion, and can be easily removed from the frame and mesh in one pull. This tape stays together, without breaking or shredding, and helps to speed up the screen cleaning process.
PMI’s 321 Block Out uses the same adhesive and backing as Split Tape allowing for a clean removal. Just without the blue adhesive-free areas. For taping further into the screen, taping the print side of screens as a block out tape, and masking the inside of wood frames.
