Poly White, Ultra Low Bleed

Poly White is a ultra low bleed, high pigment, fast flashing, low tack, non-phthalate plastisol screen printing ink. It is specifically formulated to help block dye migration problems on certain problem polyester content fabrics.

For optimum bleed resistance, use an 86 t/in or 34 t/cm mesh screen base plate and overprint with an 110 t/in or 43 t/cm mesh screen Avoid over-flashing, to avoid poor inter-coat adhesion of overprinted colors or increased dye migration. Adjust flash settings so that the ink is just dry to the touch.
For ultimate bleed resistance, print-flash-print-flash 2 basecoats of Guardian Gray™ 7043 through either an 110 t/in or 43 t/cm mesh screen or an 86 t/in or 34 t/cm mesh screen. Followed by print-flash-print 2 topcoats of Poly White 741 through an 110 t/in or 43 t/ cm mesh screen. Again, avoid over-flashing, as it can result in poor inter-coat adhesion
of overprinted colors or increased dye migration. Adjust flash settings so that the ink is just dry to the touch.

Dwell time should be increased to adjust for thick ink deposits. Failure to fuse the ink properly causes in cracking, poor adhesion and poor wash fastness. Higher than recommended temperatures or longer than necessary dwell times may increase dye migration.
