Heat stamping

This technology is used to apply a metallic layer on the surface of the printed material. The application of heat and pressure on the rear of a metallic film activates the adhesive, which attaches and then separates a portion of the metallic film in the shape of the design on the stamping plate. The results are typically effective and rich in detail, and are often used on different types of exclusive and high-end products. This technology may be used to secure original products and function as a type of trademark when a holographic film is used or a managed hologram is applied.

Cold stamping

This represents a simpler alternative to hot stamping where the adhesive is applied by offset or flexographic printing onto a material and the metallic film is then stamped to the surface; the adhesive is activated as it passes under a UV lamp and the excess is then removed, to create a metallic image in the places where the adhesive was previously applied. Given that the film must be transparent to UV light, the resulting effect is not as perfect as in the case of hot stamping, and the same applies to the rendering of details. An advantage is the lower price for preparing printing plates and higher speed of application; however, the higher price of these films is a drawback. Extrusion films offer a broad range of options; this silver form can then be printed with another colour to create eye-catching graphics.

Relief stamping

Relief printing, or embossing, is created using two printing plates (a negative and positive) to plastically deform the material and represents a suitable complement to hot and cold stamping and screen printing technologies. The most striking effects can be achieved on structured wine materials, for which this technology is most often used.
