On the worst colored fabrics or poly clothing that is dye sublimated with designs like Camo and Digi-Camo, LC0550 Barrier Grey is an under base product intended to prevent unstable garment dyes from migrating into a Chill top white or Chill top color. For printing on polyester clothing made with unstable dyes or prone to shrinkage when exposed to heat, chill products cure as low as 270°F/132°C.
Highlights
Lower cure temperatures allow for better control on fabrics that may shrink or distort under higher temperatures
Works well on manual or automatic presses
Shears down quickly to a creamy, smooth body
Excellent bleed resistance at a wide temperature range, low cure
Energy savings and cooler operating temperatures
Printing Tips
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.
Use 86–110t/in mesh screens for best performance and opacity
For printing under a white or color over-print it is typical to print two strokes of Chill Barrier Grey, flash until dry to the touch, and then print white or colors over the barrier under base, flashing as needed.
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.
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.
