Printers who have invested in multi-unit presses, (6 to 8 print units with double coaters), may be reluctant to sacrifice one or two units for cold foiling or cast and cure effects. Cold foiling has traditionally been a process that requires 2 units of a press, one for the adhesive, the next for the foil pressing. Cast and cure similarly required a unit for the film application and curing following a varnish coat applied through a litho unit or an in-line coater. Foiltone have recently installed cast and cure on an 8 colour Man Roland press with twin coaters.
The film application and casting is being done through one of the drying stubs, an installation that allows the Printer to achieve spot or full coat holographic effects in one pass without losing any of the functionality of the press. This solution has also been successfully installed on Komori and Mitsubishi presses with twin coaters. Cast and cure is a low-cost process that gives additional added value for all packaging or commercial print.
By placing the process on a drying stub current designs can be further embellished with no compromise or additional processes. In 2 of the 3 installations the Printers also have cold foiling in-line. This gives potential for a wide range of effects and finishes—in-line, single pass!
