Abstract (en)
[origin: WO2017162601A1] The invention relates to a method (400) for protecting the data printed on a transfer film of a thermal-transfer plastic card printer having a print head, which protection method (400) comprises: a first printing step (402) in which the transfer film and the plastic card travel simultaneously over a printing length Lo under the print head, and in which the print head heats up according to the text to be printed; a rewinding step (404) in which the transfer film is rewound over a rewinding length Lo +/- d different from the printing length Lo, and in which the plastic card is moved back upstream of the print head; a subsequent printing step (408) in which the transfer film and the plastic card travel simultaneously over another printing length under the print head, and in which the print head heats up according to the text to be printed; and an ejection step (410) in which the plastic card is ejected from the printer.
