For small pinholes or scratches in the emulsion, blockout pens are the quickest and easiest way to repair. You can use tape if you would like. However, this takes more time to apply and more time to get out of the screen mesh in the washout booth. We would much prefer to clean the blockout as it dissolves very easily with no residue left behind.
