Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] figure 2 A flowchart showing a two-color double-sided printing method according to an embodiment of the present invention, including:

[0026] Step S10, acquiring two original four-color page dot matrixes each time according to the printing order;

[0027] Step S20, respectively extracting valid first color data and second color data in the dot matrix of two original four-color pages;

[0028] Step S30, writing the extracted first color data and second color data respectively into the first color data, second color data, third color data and fourth color data of a new four-color page dot matrix.

[0029] Existing printing software is processed for the CMYK four-color printing system, so if two spot colors are used for printing, in the page dot matrix generated by two-color double-sided printing, only the data of two colors ...

Abstract

The invention provides a double-color double-sided printing method, which comprises the following steps of: acquiring two pages of original four-color page dot matrixes every time according to the printing sequence; respectively extracting effective first-color data and second-color data in the two pages of original four-color page dot matrixes; and respectively writing the extracted first-color data and the second-color data into the first-color data, the second-color data, third-color data and fourth-color data of one page of new four-color page dot matrix. The invention provides a double-color double-sided printing device comprising a printing controller, wherein the printing controller comprises an original page acquisition module which is used for acquiring two pages of original four-color page dot matrixes every time according to the printing sequence, an extraction module which is used for respectively extracting the effective first-color data and the second-color data in the two pages of original four-color page dot matrixes, and a new page generation module which is used for writing the first-color data and the second-color data extracted respectively into the first-color data, the second-color data, the third-color data and the fourth-color data of one page of new four-color page dot matrix. According to the double-color double-sided printing method and device disclosed by the invention, printing efficiency is improved.

Description

technical field [0001] The invention relates to the field of printing, in particular to a two-color double-sided printing method and device. Background technique [0002] RIP (Raster Image Processor, Raster Image Processor) is used to convert page description files (such as PDF files generated by typesetting software) into raster images, and use them on raster imaging equipment (such as photosetters, computer-to-plate machines, digital printing machines) on output. Any job to be printed must be processed by RIP to generate a rasterized image dot matrix corresponding to each page (hereinafter referred to as a dot matrix page for short). [0003] The print controller is installed on the host computer, reads the page dot matrix of the print job from the hard disk, sends print configuration parameters, print control commands and print data, and realizes the control of the print process. [0004] The digital control system (Digital Control System, hereinafter referred to as the...
