Place the foil screen in the screen printer. Use a soft squeegee and slow
stroke to make a smooth even thick film of adhesive on the shirt. A sequence of
print, flash, print may be necessary to both have the adhesive engage the fibres
of the shirt and be above the shirt enough to adhere the foil. Too little glue
causes poor adhesion; too much will cause the glue to melt from under
the foil, resulting in uneven edges. The printed glue should have a smooth,
glass-like finish. Foil will adhere to both plastisol inks as well as foil
adhesives so you must either combine foil with water-based inks or else use a
“foil resist” additive in the plastisol inks in the non-foil portions
of your print. You may print a grey layer of ink under a silver foil and a
gold/yellow layer of ink under a golden foil, etc., or dye the glue grey or gold.
Doing this means someone will not see that the foil is peeling or falling off of
some pin spots after the first washes, and the image will look fresh for longer.
