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 fibers 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.
