General Information

Union’s Black Light Clear when printed remains almost colorless in normal indoor or outdoor lighting conditions but emits a blue glow when exposed to black UV light. Black Light Clear is normally used in highlight areas of designs.

Opacity

Not opaque. This ink is transparent.

Mesh

Use polyester monofilament meshes from 85 to 156 threads/inch (34-91 threads/centimeter). Thicker ink layers will provide more dramatic effects although they will be more visible under normal lighting.

Stencils

Use any direct emulsion or capillary film compatible with plastisol inks.

Additives

These inks are supplied ready to print. Always stir the ink well to determine the actual viscosity before adding any reducer. Reducing the ink reduces the intensity of the glowing effect. Never add mineral spirits to any plastisol ink. If necessary reduce with small amounts (1-3%) PLUS-9000 Reducer/Detackifier.

Printing Instructions

For optimum results adjust the off-contact distance and squeegee pressure to print
the ink layer on top of the printed fabric rather than pushing the ink through it.

Curing Instructions

The inks will cure and withstand repeated washings when the entire ink film reaches 300°F (149°C). Proper curing is very important. Poor washability of the print can generally be traced back to under-curing.

Wash-Up

Clean the screens and squeegees with mineral spirits or any screen wash designed for plastisol inks.

Washability

Thicker ink layers will be more resistant to laundering but will require more curing. Caution: Do not dry clean or iron printed areas.

Durability of the Black Light Effect

There are no known effects to the durability of prints made with Black Light Clear because of exposure to sunlight or regular laundering of garments.

Storage

This ink has an indefinite shelf life if stored at room temperature.

Caution

Always test this product for glow, curing, adhesion, washability and other specific requirements before using in production.
