COLD FOIL

An alternative to hot foil stamping that can be done in-line on a web or sheetfed press. Two print units and a special apparatus are required. The first print unit applies a spot adhesive to the substrate through the normal lithographic process (with the adhesive essentially acting as an ink). In the 2nd print unit a foil film is fed between the blanket and impression cylinders, pressing the foil to the substrate where it sticks to the adhesive areas. The spent film is re-spooled on a take-up roll. The process takes place at normal press speeds. Other print units can print color over the foil to achieve a wide range metallic shades and patterns. Coatings can add protection or other effects.
