Use smallest line anilox possible, it should be lower than 300line/inch. An anilox Below 150line/inch is recommended. The pigments are abrasive to steel, use ceramic anilox, with a reverse angle, ceramic tipped doctor blade. This product is formulated to be press ready and can be printed over Rotary Screen, UV Flexo and Water Base Flexo inks. Phosphorescent pigments have a high density and will settle. This Varnish must be stirred well before and during use. The main objectives in this process is to increase the coating weight. Glow-N-Dark Varnish has a larger particle size (4μ) than regular inks. Achieving the brightest glow requires the highest coating weight possible. We suggest using a high volume anilox, hard sticky-back, photopolymer plates with a soft durometer, very little nip pressure. Printing over a white or a light colored substrate is also suggested.
After press/job set up is complete, inspect a portion of the printed web for all applicable and specified properties. These properties include but are not limited to: cure, adhesion, mar and rub resistance, product resistance, gloss, and coefficient of friction. These tests should be performed prior to beginning the full production run.
Use oxygenated wash solvent for clean-up before and after printing. Do not use wash-ups that contain acids or water.
