Low-bleed ink for the nastiest,
bleeding 100% polyester and other synthetic fabrics prone to dye
migration. Print with 83-110 mesh. This is a heavily pigmented ink
designed to print on dark garments. For increased opacity, use 50
micron capillary film on a very tight mesh in a Newman frame. Do NOT
add any form of reducer, because that could lead to dye migration. If
the ink is too thick, the ink can be made to print easier by (1)
vigorous stirring, e.g. a spade drill bit on a variable speed hand drill
(but cover the top with cardboard and secure in a vise), (2) blending
with a medium pigmented ink of the same color in a ratio of 80% Poly
with 20% of the medium pigmented ink, or (3) blending with soft hand.
Blending with soft hand might result in loss of opacity. The
worst colors for dye migration are red, maroon and green. Synthetics
transmit heat unlike 100% cotton and will get hotter faster. Excessive
heat can cause dyes to sublimate, and therefore excessive heat can be a
cause of dye migration. The worst case of dye migration comes of tye
dyes. They should be run through the conveyor as hot and slow as the
fabrics can withstand, and then turned over and run through the conveyor
again so the fabrics are too hot to touch. Then print with the POLY
inks. |
