Union Polyester Ink - LB University Blue
Approximate PMS Match = 278C.
Opacity: Polyester low-bleed plastisols are high-opacity, low-bleed inks.
Mesh: Print through 74T-110T (29-34 metric) monofilament polyester. For maximum opacity use 62T (24 metric).
Stencils: Any direct emulsion or capillary film compatible with plastisol inks.
Additives: Polyester low-bleed plastisols are supplied ready to print. Since plastisol inks “body up” as they sit in the container you should always stir the ink well to determine the actual printing viscosity before adding any reducer. The viscosity of Polyester low-bleed plastisol has been carefully formulated to sit on top of the fabric when printed. Reducing will cause the ink to penetrate into the fabric, affecting coverage. Any chemical modification will also diminish the ink's bleed resistance. Care should be taken if modification is deemed necessary. Use very small amounts; 5-1% by weight of PLRE-9100 Concentrated Plastisol Reducer should be adequate. Never add mineral spirits to any plastisol ink.
Printing Instructions: For the best coverage, bleed resistance, and brightest prints, adjust the off-contact distance and squeegee pressure to print the ink layer on top of the printed fabric rather than pushing the ink entirely through it. Also be sure to follow recommended emulsion coating techniques as well as exposure settings.
Curing Instructions: Plastisol inks will not air dry and must be heat cured. Polyester low-bleed plastisols will fully cure and withstand repeated washings when the entire thickness of the ink deposit reaches 300°F (149°C). Be careful ink film temperatures do not exceed 330°F (166°C) as this temperature may facilitate dye migration.
Caution: Always test this product for curing, adhesion, crocking, opacity, bleed resistance, washability, and other specific requirements before using in production. Because of the thick ink deposits required by athletic printers, Polyester Low-Bleed plastisols may require higher, dryer temperatures or slower belt speeds for the ink deposit to reach the recommended curing temperature. For 100% polyester fabrics prone to extreme dye migration consider using Union’s Barrier Clear PLHE-9040 or Barrier Grey PLHE-1500 as an underbase especially when light or white overprint colors are required.
