Description:

Union Ink™ Gen2 LC Poly White is a high opacity low bleed low cure white that produces a very soft, matte to low gloss finish with terrific fiber mat-down and great dye blocking ability on a wide range of fabrics. UPLC1071 Poly White shears down quickly to print like similar low cure products, but retains an even flood and does not "puff' as much as competitive products resulting in excellent printability and detail.

Printing Tips

Use 86-230t (34-90t/cm) mesh screens for best performance and opacity

For best results, use a print-flash-print technique to ensure sufficient ink deposit on dark fabrics.

For challenging polyester fabrics, use Union Ink™ UPLC1550 Low Cure Barrier Grey or UPLC8550 Barrier Black as a base layer to achieve maximum bleed resistance.

Adjust flash cure temperature and dwell time so ink is just dry to touch. Avoid excessive flash temperatures to protect fabric and migration of dyes. Depending on flash unit, a 3 - 5 second flash is adequate.

A behavior for high-opacity low cure inks is to "body-up" or gain viscosity when at rest. Be sure to "Pre-shear" or agitate this ink before use to achieve optimal flow before printing. Be careful to not use high-speed drills or similar equipment that will create friction-heat that can cause the ink to begin to cure. Store ink buckets up off of cold floors to reduce pre-shear time.

Adjust your print parameters to allow this ink to clear fully on the second stroke using medium to low pressure for best dye blocking and opacity. As this ink shears down, less pressure will be required. Adjust accordingly.

Curing is a time and temperature process. Using a lower temperature, at a lower belt speed will provide the best result without damaging the fabric.
