Discharge is a chemical reaction that destroys the ability of selected dyes to reflect a color. The reaction takes place at temperatures above 180 F (83°C). Only selected dyes on natural fibers are dischargeable. As specifications of shirt manufacturers are always changing, always test first and last shirt of a carton before production. Read understanding discharge by Pavonine before printing.

SPECIFICATIONS
USES: Produces brilliant color on dischargeable fabrics. Leaves a very soft hand.

FINISH: Equal to fabric printed.

OPACITY: All colors appear brilliant by eliminating the underlying color
.
DRYING TIME: The discharge reaction takes place at temperatures above180 F (83 C) while water is present. Driving off the water stops the reaction and will result in dull colors is incomplete. Printers with dryers designed for plastisol may have to lower temperatures and extend dwell times. After discharge, curing requires at least one minute at 330 (165 C) to obtain washability.

SCREEN FABRIC: Use monofilament polyester depending on material being printed. 156-178 mesh for normal printing.

SCREEN COATING, FILM, BLOCKOUT: Use water resistant emulsion, preferable with hardener.

MODIFIERS: ZFS (zinc formaldehyde sulfoxylate) added from 3 to 8% is required for discharge. Test for the minimum needed for each fabric.

PRINT TECHNIQUE: Very little squeegee pressure is required and there is little drag for long runs without fatigue. Minimum off contact is recommended, but will print well on contact.

SQUEEGEE: Soft to medium in the 60 to 70 range.

WASHUP: Use water to clean screens and tools, or biodegradable washups 2500, 2550 or 2510 screen wash gel for badly dried in screens.

ALWAYS TEST PRINT BEFORE PRODUCTION
