Abstract

A printing method uses a reaction liquid containing an aggregating agent capable of causing the aggregation of a color material. This printing method includes: applying a first reaction liquid to a recording medium; applying a background color ink that contains a color material for a background color to a region of the recording medium which is coated with the first reaction liquid; drying the recording medium coated with the background color ink by heating the recording medium; applying a second reaction liquid to a region of the dried recording medium which is coated with the background color ink; and applying an image forming ink that contains a color material having a color different from that of the background color ink to a region of the recording medium which is coated with the second reaction liquid.

First claim

What is claimed is:

1 . A printing method that uses a reaction liquid containing an aggregating agent capable of causing aggregation of a color material, the printing method comprising:
applying a first reaction liquid to a recording medium; applying a background color ink to a region of the recording medium which is coated with the first reaction liquid, the background color ink containing a color material for a background color; drying the recording medium coated with the background color ink by heating the recording medium; applying a second reaction liquid to a region of the dried recording medium which is coated with the background color ink; and applying an image forming ink to a region of the recording medium which is coated with the second reaction liquid, the image forming ink containing a color material having a color different from that of the background color ink.

2 . The printing method according to claim 1 , further comprising applying an overcoat liquid to a region of the recording medium which is coated with the first and second reaction liquids after the applying of the image forming ink.

3 . The printing method according to claim 2 , wherein
the overcoat liquid is applied so as to cover the region of the recording medium which is coated with the first and second reaction liquids.

4 . A printing method that uses a reaction liquid containing an aggregating agent capable of causing aggregation of a color material, the printing method comprising:
applying a first reaction liquid to a recording medium; applying an image forming ink to a region of the recording medium which is coated with the first reaction liquid, the image forming ink containing a color material for use in creating an image; drying the recording medium coated with the image forming ink by heating the recording medium; applying a second reaction liquid to a region of the dried recording medium which is coated with the image forming ink; and applying a background color ink to a region of the recording medium which is coated with the second reaction liquid, the background color ink containing a color material for a background color which has a color different from the color material of the image forming ink.

5 . A printing apparatus comprising:
a reaction liquid application section that applies a reaction liquid to a recording medium, the reaction liquid containing an aggregating agent capable of causing aggregation of a color material; a background color ink application section that applies a background color ink to the recording medium, the background color ink containing a color material for a background color; an image forming ink application section that applies an image forming ink to the recording medium, the image forming ink containing a color material having a color different from that of the background color ink; and a drying section that dries the recording medium by heating the recording medium, the reaction liquid application section applying a first reaction liquid to the recording medium, the background color ink application section applying the background color ink to a region of the recording medium which is coated with the first reaction liquid, after the applying of the background color ink, the drying section drying the recording medium by heating the recording medium, the reaction liquid application section applying a second reaction liquid to a region of the dried recording medium which is coated with the background color ink, the image forming ink application section applying the image forming ink to a region of the recording medium which is coated with the second reaction liquid.

6 . The printing apparatus according to claim 5 , further comprising a transport section that can transport the recording medium in a first direction and a second direction, the first and second directions being opposite to each other,
wherein the recording medium is coated with the first reaction liquid and the background color ink and dried by the drying section while being transported in the first direction by the transport section, then the recording medium is transported in the second direction by the transport section, and the recording medium is subsequently coated with the second reaction liquid and the image forming ink while being transported in the first direction by the transport section.

7 . The printing apparatus according to claim 5 , further comprising an overcoat liquid application section that applies an overcoat liquid to a region of the recording medium which is coated with the first and second reaction liquids.
