METHOD OF INKJET NO-PRINTING PLATE DIGITAL FULL COLOR PRINTING, AND PRINTING MACHINE

摘要

PROBLEM TO BE SOLVED: To produce a high quality printing image in a short time at a reduced cost onto an object to be printed such as a foamed resin which has ink absorbency and is vulnerable to heat.;SOLUTION: A predetermined printing image is printed onto an object to be printed by ejecting one of an ultraviolet ray hardening type ink, an electron beam hardening type ink or an infrared ray hardening type ink having a predetermined concentration onto a predetermined position of the object 2 to be printed from inkjet printer heads 3A-3D to form the printing image, and thereafter carrying out over a whole printing region of the object to be printed the printing operation for a head width which radiates one of the ultraviolet rays, electron beams, or infrared rays with an intensity appropriate for the ink concentration of the printed part from a radiating device 6 to instantaneously harden and dry the ink. A higher quality printing image is printed in a short time period on the object to be printed by printing the same image as the printing image so as to be superimposed.;COPYRIGHT: (C)2009,JPO&INPIT
