To reduce unintended variables, shops will need an auto-coater to apply emulsion to the screen rather than doing it by
hand. This ensures the consistent and proper emulsion EOM. The emulsion used is typically a dual-cure water-resistant
pure photopolymer.
Screens are locked in with a three-point registration system for easy registration and set-up on press later. These systems
are connected to the shop’s server, and files are loaded and ripped in a print queue. The screen (or screens) are imaged
and exposed in one step. After imaging, the screens are ready for washout. Shops with an LTS usually use an automated
high-pressure water washout system, as there isn’t any toner or wax on the screen to signify the areas to be washed out.
A worker can still do this by hand, but small details can get missed. An automated system prevents challenges with parts
of the image not being washed out properly.
