Union Low Cure Light Grey

PRINTING TIPS

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

For challenging polyester fabrics, use Union Ink UPLC1555 LB Sport Victory Barrier Grey as a base layer to achieve maximum bleed resistance.

Adjust flash cure temperature and dwell time so ink is dry to the 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. Do not use high-speed drills or similar equipment that will create friction-heat that can cause the ink to begin to cure. To reduce pre-shear time, do not store ink buckets on cold floors.

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. Use a low temperature and low belt speed to achieve the best results without causing damage to the fabric.

Avoid "hot stacking" printed poly garments coming off the dryer belt. This will help stabilize the shirt pigment.
