<P>PROBLEM TO BE SOLVED: To provide a post-treating method of a printing part, with which recorded images with high color tone, high image quality and high image fastness can be obtained, and a post-treating device therefor. <P>SOLUTION: This post-treating method is applied to a printing part, to which printing is performed on a recording medium with water-color ink including at least micelle associating bodies containing an alkali neutralized matter of copolymer including respective constitutional units each from at least one kind of monomers selected from the group consisting of alkene, styrene, its derivative, vinylnaphthalene or its derivative, at least one kind of monomers containing ionically dissociating acid groups and at least one kind of α,β-ethylenic unsasturated carboxylic acid alkyl esters, pigments and aqueous media under the condition that (1) an exposing treatment of the printing part to ozone atmosphere or (2) an exposing treatment of the printing part to acidic atmosphere is performed within 10 seconds after printing. Further, this post-treating device is equipped with an ozonizing device for exposing the printing part to ozone atmosphere or an acidic atmosphere generating device for exposing the printing part to acidic atmosphere. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
