Abstract
A transfer lamination method uses a transfer lamination device including a transfer ribbon comprising a transfer film on a carrier web, a print unit comprising a print head, and a transfer unit configured to transfer a film section of the transfer film to a substrate. In the method, the transfer ribbon is fed in a feed direction past the print unit and the transfer unit. Tension is generated in the transfer ribbon using the print head while processing the transfer ribbon using the transfer unit.
Claims16
A transfer lamination method using a transfer lamination device, which includes a transfer ribbon comprising a transfer film on a carrier web, a print unit comprising a thermal print head including a plurality of heating elements, and a transfer unit configured to transfer a film section of the transfer film to a substrate, the method comprising:
- feeding the transfer ribbon in a feed direction past the print unit and the transfer unit;
- and
- tensioning a portion of the transfer ribbon extending from the transfer unit toward the print head using the print head while processing the transfer ribbon using the transfer unit, comprising resisting feeding of the transfer ribbon in the feed direction including pinching the transfer ribbon between the print head and a print roller of the print unit.
A method of performing a transfer lamination using a transfer lamination device, which includes a transfer ribbon comprising a transfer film on a carrier web, a print unit comprising a print head and a print roller, and a transfer unit comprising a transfer roller configured to transfer a film section of the transfer film to a substrate, the method comprising:
- feeding the transfer ribbon in a feed direction past the print unit and the transfer unit;
- printing an image to a surface of the film section of the transfer film using the print unit;
- bonding the film section to a surface of the substrate using the transfer roller while generating tension in a first portion of the transfer ribbon extending from the transfer roller to the print head including pinching the transfer ribbon between the print head and the print roller;
- and
- peeling the carrier web from the film section while generating tension in a second portion of the transfer ribbon extending from a trailing end portion of the substrate to the print head including pinching the transfer ribbon between the print head and the print roller.
