Embossing: Brilliant effects due to hot foil embossing

Example embossing: radiator grille

Hot foil embossing produces results that are difficult to achieve with other printing processes. Matte colours, high-gloss metallic or partially uncoloured gloss spots are just a few of the many possibilities. In addition, there are relief embossings in plastic, which, depending on the incidence of light, have an extraordinarily decorative effect.

Process engineering

Hot stamping is a high-pressure process in which the motifs to be printed are embossed on a metal die. This die is heated on the embossing machine and kept at a constant temperature. An embossing foil runs under the embossing die, which separates from the substrate material under high pressure and heat and then passes to the material to be printed. During each embossing process, the film adheres inseparably to the printed material.

Embossing foils for the hot stamping process are in principle opaque. They are available in countless colours, metallized, matt, glossy, in brilliant decors and with holograms. All films are very durable and have an extraordinarily long service life. 

Important areas of application

Another example of embossing

Hot foil printing is the crowning glory of all decoration and marking processes. The printing process is therefore often used to print on visible parts made of plastic and leather. Embossing foils in silver, gold or other glossy variants give the printed material a noble, valuable impression.

Examples:

  • Marking/labelling of plastic containers and packaging (e. g. cosmetics industry, advertising industry)
  • warnings
  • Company labels and labels
  • Surface finishing of add-on parts (e. g. automotive industry)
  • decorative branding

Hot foil embossing is the ideal printing process, especially on dark substrates on which conventional printing processes cannot achieve 100 percent coverage.
