Foil Printing

Foil printing lays a tacky adhesive through the screen in the shape of the art, flash-cures it just enough to stay sticky, then presses a sheet of metallic foil onto it at roughly 300-320°F for a few seconds so the aluminized layer bonds to the adhesive and releases from its carrier film. Peel the carrier while the adhesive is still warm and the foil transfers cleanly; peel too soon or too late and you get pinholes, or a foil sheet that never lets go at all.

On a finished shirt it reads as a mirror-bright, slightly raised metallic surface — gold and silver read best on black, navy, or maroon, which is why foil printing shows up so often on team championship shirts and holiday retail drops. We've had a customer send back an entire box because they machine-dried a foiled hoodie and the foil had cracked into a spiderweb pattern across every letter.

Print shops keep foil artwork chunky: bold block letters, thick outlines, and simple shapes bond reliably, while fine serif text or tight halftone dots trap adhesive unevenly and leave gaps in the metallic layer. Because foil doesn't stretch with knit fabric, it's also kept off high-movement spots like side seams or sleeve cuffs where flexing cracks it fast.

The most common misunderstanding buyers have about foil printing is treating it like a regular plastisol job that can go through a hot wash and dryer — foil wants cold water, inside-out washing, and air drying, and a care label that says otherwise sets the customer up to watch the shine flake off in a few washes.
