PERMASET AQUA Print Retarder is an additive to lengthen open screen time for all water-based inks. PERMASET Print Retarder slows the drying process avoiding clogging of screens.
It is also beneficial in enabling easier release of the screen from the print during the printing process.
As a general guide, add PERMASET Print Retarder at 1-2% in PERMASET AQUA® and PERMATONE® inks, 2-5% in PERMASET SUPERCOVER® inks and 1-2% for PERMAPRINT® Premium inks. Stir in thoroughly.
Alternatively, PERMASET® Print Retarder can be diluted from 50-90% with water in a spray bottle and sprayed over the ink film on the screen between prints.
A highly recommended additional option is to spray the diluted mixture over the screen around 10 minutes before use, but definitely after registering the screen and taping off all crop and registration marks. Allow to soak in for 5-10 minutes. Then, with a lint-free rag, wipe over all dry areas of emulsion, top and bottom and wipe excess mixture off the screen. When the screen image area no longer feels damp, add ink into the screen and commence printing.
