Abstract
In a method for coating the recording surface of an information card by selectively using one of protective films of various types, the selected protective film loaded in a coating device is thermally transferred to the card at the optimal thermal-transfer temperature and optimal feeding speed determined according to the film type of the loaded protective film which is automatically identified. The film type of the protective film is recognized by detecting at least one discrimination mark on a film ribbon for the protective film by use of one or more mark sensors. The discrimination mark also serves as positioning means for the protective film in coating. By thermally transferring the protective film to the card at the optimal thermal-transfer temperature and optimal feeding speed, a high-quality information card coated with flat layers including printing ink layers and protective films and having excellent peel strength can be produced.
