Inkjet printing correction method, inkjet printing apparatus and multifunctional one-piece machine

Abstract

The invention discloses an inkjet printing correction method, an inkjet printing apparatus and a multifunctional one-piece machine. The method comprises the following steps of: printing a first test pattern file to ensure that the inkjet printing apparatus outputs a test pattern; scanning the test pattern to obtain a second test pattern file; comparing each second block separation distance in the second test pattern file with each corresponding first block separation distance in the first test pattern file to obtain corrected separation distance difference data; and reading the corrected separation distance difference data to ensure that the inkjet printing apparatus determines whether to shot ink in advance or delay the shooting of the ink according to the corrected separation distance difference data. The method corrects the differences between each block and each corresponding physical block, and corrects all blocks in a physical test pattern into all first blocks in the first test pattern file, so distortion phenomena cannot be generated; besides, the method directly corrects printed physical pictures, so the errors caused between internal machines of the inkjet printing apparatus are corrected at the same time.

Description

technical field [0001] The invention relates to an inkjet printing device, in particular to a calibration method for inkjet printing performed by the inkjet printing device. Background technique [0002] The general inkjet printing device is used to print out the file in the computer and becomes a paper document, and about the known inkjet printing device please refer to figure 1 , which is a schematic structural view of a known inkjet printing device. Inkjet printing device 1 comprises ink box 10, ink nozzle (not marked among the figures), transmission mechanism 11, paper input box 12 and output box 13, and ink box 10 is used for storing ink, and ink nozzle is used for emitting ink, and set At the bottom of the transmission mechanism 11 , the transmission mechanism 11 is used to move the ink nozzles so that the inkjet printing device 1 can spray ink anywhere on the blank paper P. The input tray 12 is used to place blank paper P, and the output tray 13 is used to place pri...

AI Technical Summary

Problems solved by technology

[0006] Although the method of the known technology can make the spacing of all blocks equal, but after comparing the original first test pattern file T and the adjusted test pattern, it can be found that all the blocks in the adjusted test pattern are slightly offset Not in the original position, that is to say, the document printed by the adjusted inkjet printing device 1 has distortion phenomenon, therefore, a kind of inkjet printing correction method without distortion is still needed
