  • Patent number: 8998359
    Abstract: Disclosed are a multicolor overprint control method and device applicable to an intermittent printing apparatus. According to the operating characteristic of the intermittent printing apparatus, the method solves the problems of overlap and inaccurate overprint of various colors during intermittent printing by controlling the relationship between the distance between adjacent color group modules of different colors and the motion distance between uniform segments of the intermittent printing apparatus. In addition, the method also sets different inkjet printing modes in accordance with whether the detected inkjet printing of the same color group module is in a first period, thereby solving the problems of printing media waste and discontinuous printing data. The method achieves multicolor digital inkjet printing by combining the unique motion mode of the printing media thereof, and makes printing contents flexible and changeable on the basis of guaranteeing printing efficiency.
