GLOSSY SILVER FOIL – IN LINE DIELESS

API Foilmakers’ TU sheet fed cold foil is a free releasing foil with good adhesion onto cold foil adhesives. This allows in-line or off-line over-printing with UV drying offset inks.

Using the same principles as narrow web cold foil, this technique involves printing a UV-reactive adhesive and transferring the foil without the use of a die.

Sheet-fed cold foil is used as an alternative to laminated or metallised substrates for cartons and labels with a large area of metallic background.

In terms of foil performance, over-printability is key and compatibility with both conventional and UV-cured offset inks essential. For maximum press speeds, the foil needs to be free releasing but not so flakey that edge definition is lost or print units become contaminated with foil residues. API Foilmakers’ TU grade has been proven at press speeds in excess of ten thousand sheets per hour, including long runs with minimal offsetting of foil onto print blankets.
