Besides pad printing, SeitzDruck specialises in the refinement of plastic products by means of hot foil stamping. With this technology, we create noble surfaces with metallic gloss effects in outstanding quality.

Over the years, we have gained a lot of experience with this technology and can confidently call ourselves experts in hot foil stamping. The process is excellently suited for technical parts of any kind, whether for prototypes, small or large series. For this purpose, only the material of the parts to be printed must be heat-resistant to a certain degree and have a suitable surface structure and adhesion.

We at SeitzDruck use hot foil stamping to create a wide variety of motifs. Metallic, glossy print motifs are particularly suitable for printing, resulting in very interesting optical and haptic effects. In addition, highly decorative contrasts can be achieved between glossy and matt surfaces. The refined products are given a particularly high-quality appearance by the technology. Of course, hot foil stamping can also be applied on both sides of the workpieces. This only requires a second working cycle. Products embossed with hot foil are used in many industries.

These include automotive, household appliances, the toy industry and many others. If you take a look at our references, you will find some examples of the applications of objects that we have realised for our customers. With our know-how and our modern machines we can offer you optimal quality at best conditions.

How does the (hot) foil embossing work?

Historical precursors of the process are blind embossing and relief embossing. Blind embossing uses a stamp to deform the printing material - usually paper or cardboard, but also leather - without applying ink. The relief embossing functions similarly, but is more complex. Logos or lettering appear sublime from the ground, which greatly enhances the haptic effect. This method also allows very fine curves and edges to be achieved.

Hot foil embossing now makes it possible to also set off the embossing in colour. For this purpose, a special foil is inserted between the printing substrate and the die, which transmits its shape by means of pressure and heat from the die. Embossing rollers are also used instead of stamps. The film itself consists of several layers. On the carrier or base layer there is a separating layer. This melts when the hot stamping tool hits it and releases the transfer layers above. These in turn comprise an adhesive layer and an optically effective layer. The adhesive layer, an adhesive, ensures that the optically effective layer is permanently bonded to the printed object in a smudge-proof manner.

One of the biggest advantages of hot foil stamping is the possibility to reproduce logos, graphics and lettering in a metallic shine with the aid of foil. This effect cannot be achieved with any of the usual printing processes using liquid inks. In addition, no drying or curing times are required as the plasticizing process takes place during the embossing process.

In principle, hot foil stamping is a high-pressure process because the motif is engraved on the stamp and brought to the material by high pressure.
