PLASMA ELECTRON BEAM TREATMENT INKJET-PRINTING DEVICE

WIPO Patent Application WO/2020/066663

A1

The present invention addresses the problems of: obtaining a device enabling reliable curing even in cases of printing using an ink that does not contain a photopolymerization initiator, and enabling printing without causing a substrate surface subjected to printing to be degenerated; and obtaining a device that yields a high-quality image free of running even when dots of respective colors of ink overlap, because the surfaces of the dots of ink have been cured by atmospheric-pressure plasma after printing of each of the colors. Provided as a solution is an inkjet printing device comprising: an inkjet printing unit which is provided with inkjet nozzles (N) and plasma spouts (21) and which moves in a perpendicular direction to a direction of movement of a printed substrate (S) and in parallel to the printed substrate (S) surface; and an electron beam irradiation unit on the downstream side of the direction of movement of the printed substrate (S) relative to the inkjet printing unit.
