Offering unlimited design possibilities, Kurz hot stamping foils are utilized on a wide assortment of products. These include packaging, greeting cards, electronic devices, household appliances, cosmetics, textiles, furniture, automotive parts, and numerous other items. These magnetic foils and holograms provide effective and attractive brand name protection, as well as increased security for businesses.
Cold foil technology can be flexibly integrated into any printing process as the cold foil is simply applied as a “fifth colour” to the print image. This opens up many new design possibilities. Overprinting offers free choice of colours. The base colour is usually silver. The cold foil can then be overprinted with any process colours or other colours. A variety of new metallic colour tones can also 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 colours can be rasterized to produce novel colour 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%.
Design possibilities are virtually limitless and many effects 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 and fine registration marks, e.g. crosshairs.
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.
