Ink jet recording system

摘要

An ink jet recording system includes an ink jet recording device; and a control portion that controls the ink jet recording device, in which when a first mode is selected from a plurality of recording modes, the control portion performs control of recording a security image corresponding to an input image on a recording medium by performing control of forming a glitter image by a glitter ink composition in a first image area on the recording medium, forming a color image by a color ink composition in the glitter image, and forming the color image by the color ink composition on a second image area that is in contact with the first image area.

主权项

1. An ink jet recording system comprising:
an ink jet recording device; and a control portion that controls the ink jet recording device, wherein the ink jet recording device includes
a glitter ink composition including a glitter pigment, the glitter pigment being an aluminum pigment having a flat shape,a color ink composition including a pigment having a greater visible light absorbing amount than the glitter pigment, andan ejection head that ejects the glitter ink composition and the color ink composition onto a recording medium, wherein the control portion includes
a mode selecting portion that selects one recording mode from the plurality of recording modes in which at least one of an ejection amount of the glitter ink composition and an ejection amount of the color ink composition is different, andan ejection amount control portion including the ejection amount of the glitter ink composition ejected from the ejection head and the ejection amount of the color ink composition ejected from the ejection head based on an input image input by the user and the selected recording mode, wherein when a first mode is selected from the plurality of recording modes, the ejection amount control portion performs control of recording a security image corresponding to the input image on the recording medium by performing control of forming a glitter image by the glitter ink composition in a first image area on the recording medium, forming a color image by the color ink composition in the glitter image, and forming a color image by the color ink composition in a second image area that is in contact with the first image area, and wherein a color material weight A for each unit area in the color ink composition elected to the first image area in the first mode, a color material weight B for each unit area in the color ink composition ejected to the second image area in the first mode, and a glitter pigment weight C for each unit area in the glitter ink composition elected to the first image area in the first mode have the following relationships:
0.3≧C/(A+C)≧0.045,0.3≧C/(B+C)≧0.045, and1.1≧A/B≧0.9.
