Symbol application method for flat substrate

摘要

The symbol application process involves using a hot printing foil consisting of a carrier layer, a transparent protective foil and a bonding layer of colour pigment and adhesive. The bonding layer includes blind zones which do not stick when hot-printed. These blind zones (4) in the bonding layer (3) are created by the computer controlled burning out of the bonding layer. At the same time or later, the still active regions of the foil are transferred in the known manner to the substrate with the aid of a hot printing roll.
