Abstract

Official abstract text for this publication.

An object of the invention is to prevent, both bubbles and particles from being generated, when circulating ink in an inkjet head. The object can be achieved by an ink circulation apparatus, including: an ink tank that accumulates radical polymerization-type UV-curing ink so as to be in contact with gas including at least oxygen; an inkjet head; oxygen removing means that removes oxygen from the radical polymerization-type UV-curing ink; and control means that changes a mode between a first mode of removing oxygen from the radical polymerization-type UV-curing ink by the oxygen removing means and a second mode of not removing oxygen from the radical polymerization-type UV-curing ink and changes a mode from the first mode to the second mode before electric power of the apparatus is cut off.

First claim

Opening claim text (preview).

What is claimed is: 1. An ink circulation apparatus, comprising: an ink tank that accumulates radical polymerization-type UV-curing ink so as to be in contact with gas including at least oxygen; a supplying flow path that communicates with the ink tank and a supply port of an inkjet head including the supply port to which the radical polymerization-type UV-curing ink is supplied, a nozzle that ejects the radical polymerization-type UV-curing ink, and a discharge port from which…
