PERFORMANCE: Print Stark Black LB straight from the container through mesh ranging from 86 to 236 mc without modifications of the viscosity. Use finer mesh counts for softest hand and good opacity. Stir ink before use.
SCREEN COATING, FILM, BLOCKOUT: All types of stencils may be used for screen printing 50/50P Series Plastisol Inks
RECOMMENDATIONS: Stir plastisol ink before printing. Any modifiers and additives should be mixed in clean containers using clean mixer blades and ink knives. Any contamination from other ink sources could make the ink test positive for restricted phthalates. Do not dry clean, iron or bleach the printed image.
Perform fusion tests before production. Failure to cure ink properly can result in poor wash fastness, inferior adhesion, and unacceptable durability.
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. If surface is hot and tacky, the ink film has been over flashed. Reduce temperature or time to prevent an inter-coat adhesion problem.
Curing is a time and temperature process, a lower oven temperature setting with a slower belt speed while maintaining recommended ink cure temperature is always best to protect fabric, control dye migration and reduce energy consumption.
Stark Black LB can be cured at 320° F. Running at the higher temperatures and/or longer dwell times maybe required to achieve proper cure on jobs that contain cotton, high ink deposits or heavy weight garments
*Note: Poorly dyed polyester or too much heat in the curing process can overcome any low bleed inks ability to block the migration. For sever migration use a barrier base underlay.
WASHUP: Use SYS-1925 or biodegradable washup SYS-2500, SYS-2550 or SYS-2510 screen wash gel.
STORAGE AND HANDLING: 65° F to 95° F avoid direct sunlight. Never exceed temperatures above 95° F during storage
ALWAYS TEST PRINT BEFORE PRODUCTION!
