US 8,998,359 B2 · Method and apparatus for controlling multicolor overprint of intermittent print device

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.

Dependent claims

A method for controlling multicolor overprint applicable to an intermittent print device, comprising steps of:

(1) obtaining a start time signal of a uniform-speed section in an intermittent motion cycle of the intermittent print device;
(2) setting the intermittent print device to start operation upon detection of the start time signal of the uniform-speed section so that a first color module starts inkjet print until an end time of the uniform-speed section, wherein the first color module is a module into which multiple spliced imaging components in the same color are combined;
and
(3) following the end of motion in the uniform-speed section of the current color module, starting inkjet print by a next color module together with a next color start time signal of a next color uniform-speed section until the end time of the next color uniform-speed section, and repeating the step (3) until all the color modules in colors finish print.

An apparatus for controlling multicolor overprint applicable to an intermittent print device, comprising:

a uniform-speed section parameter calculating module configured to obtain a start time signal of a uniform-speed section in an intermittent motion cycle of the intermittent print device;
a first color module jet-print module configured to set the intermittent print device to start operation upon detection of the start time signal of the uniform-speed section so that the first color module starts inkjet print until an end time of the uniform-speed section, wherein the color module is a module into which multiple spliced imaging components in the same color are combined;
and
an another-color module jet-print module configured to cause a next color module following the end of motion in the uniform-speed section of the current color module to start inkjet print together with a next color start time signal of a next color uniform-speed section until the end time of the next color uniform-speed section and to repeat the foregoing process until all the color modules in colors finish print.
