METHOD FOR PRODUCING PRINTING IMAGE MADE UP OF SECTIONS ON MATERIAL TO BE PRINTED USING TWO INK JET PRINTING HEADS

摘要

PROBLEM TO BE SOLVED: To provide a printing method which is improved as compared to the prior art.;SOLUTION: There is provided a method for producing a printing image made up of sections on a material to be printed using two ink jet printing head. The method comprising the steps of: choosing a data stripe extending in an x direction and having a width DY about a location Y1 in data of the printing image; examining the data of the printing image in the data stripe for a presence of a data field of an extent dx in the x direction and dy in the y direction, in which edge detection is possible; selecting the data field and capturing an x coordinate x1 and a y coordinate y1 of the data field; producing the printing image; recording an image of a measurement field correlated to the data field on the material to be printed using a camera, wherein the image to be recorded is at a location x1, y1 and has at least a size dx*dy; carrying out the edge detection in the data of the image of the measurement field; and correcting a y position of at least one of the first and second printing heads when an edge is detected.;COPYRIGHT: (C)2014,JPO&INPIT
