Fixing pinholes in an exposed screen
There are times where defects show up in the finished screen. In some recent screens I've noticed some pinholes in critical areas of the screen. This probably comes from not enough effort degreasing my screens after reclamation. While that's good to keep in mind for a future screen, I want to get going with today's printing! Fortunately, the fix for pinholes is easy. Use some unexposed emulsion and a paintbrush and paint the pinholes over. Then put the screen back in the exposure unit (without artwork) and re-expose the screen to harden the painted in areas. Pre-existing emulsion areas can benefit from post-hardening and the filled in areas will be repaired. The screen will be ready to print in five minutes or so. Good for minor repair and better than starting over!
