Cold foil makes many things possible
  Design possibilities for cold foil

Cold foil technology can be flexibly integrated into any printing process. The cold foil is simply applied as a "fifth color” to the print image. This opens up many new design possibilities.  

 

Overprinting offers free choice of colors

The base color is usually silver. The cold foil can then be overprinted with any process colors or other colors. An astonishing variety of new metallic color tones can be created in this manner. 

 

Interaction of ink and foil

Cold foiling allows precise registration, just as with offset printing. The foil can therefore be transferred in register with the printed image. Both the foil and the overprinted colors can be rasterized to produce novel color and metallic effects. Cold foils offer a high gloss level, even for coarse rasters (25l/cm). The foil releases cleanly at surface coverages of 40 to 100%.

 

Designs and surfaces

The design possibilities are virtually unlimited. Many things can be achieved:

  • filigree patterns, fine lines and lettering down to approx. 6 pt
  • any kind of partial coverage
  • full surface foil transfer
  • small recesses

  • half tones and screens

  • fine registration marks, e.g. crosshairs

 

Holographic elements

Cold foils are also available in holographic designs. Large-area diffractive structures or single images can be selected. Besides shiny metallic foils, there are also a range of transparent holographic foils to choose from.

  

Cold foil and tactility

Relief embossing cannot be performed concurrently with the cold foil transfer process. The foil can, however, be raised or lowered by means of blind embossing in a second work operation.
