  • Patent number: 8739700
    Abstract: In a printing system in which a roll film is rolled out to be printed by a printer and the film is rolled up after printing and drying, there is a possibility that wrinkles of the film are generated when printing, and printed materials are scratched because the printed film is positioned near the printer. Both end side of a suction stage in the film delivery direction are formed in a circular arc shape, and auxiliary stages are provided near the end portions to suck and hold a film, the auxiliary stages are allowed to be moved lower than a surface of the suction stage in the state to closely attach the film to the suction stage while applying tension to the film, and the film is sucked and held on the suction stage in the state to be printed after position adjustment to a surface of a mask.
