Abstract

A liquid discharging technique is provided that conveniently carries out recording (printing) with a desired coloring relative to media (fabric or the like) with various characteristics such as an ink color development property. A textile printing apparatus 100 is a liquid discharging apparatus which discharges a liquid (an ink) onto a recording medium (a fabric 1 ) and records an image and includes a liquid discharging section (a head 41 ) which discharges the ink onto the fabric 1 based on correction image information which is corrected according to coloring information for the fabric 1 which is obtained from the fabric 1 which is supplied to the textile printing apparatus 100.

First claim

What is claimed is:

1. A liquid discharging apparatus configured to discharge a liquid onto a recording medium and configured to record an image, the liquid discharging apparatus comprising:
a liquid discharging section configured to discharge the liquid onto the recording medium based on correction image information which is corrected according to coloring information for the recording medium which is obtained from the recording medium which is supplied to the liquid discharging apparatus;
a coloring information acquiring section configured to acquire the coloring information;
a supply section configured to accommodate the recording medium before the liquid is discharged;
a transport section configured to transport the recording medium from the supply section to an image forming section where the liquid discharging section discharges the liquid and forms the image with regard to the recording medium;
a holding section configured to hold the recording medium at a region which includes the image forming section; and
a tension section configured to generate predetermined tension on the recording medium between the supply section and the holding section on the transport path;
the coloring information acquiring section being disposed between the supply section and the image forming section on a transport path where the recording medium is transported by the transport section, between the supply section and the holding section on the transport path, and between the supply section and the tension section on the transport path.

2. The liquid discharging apparatus according to claim 1 , wherein
the coloring information acquiring section has a light source which irradiates light onto the recording medium and a light receiving element which receives reflected light of the light.

3. The liquid discharging apparatus according to claim 1 , further comprising
a correction processing section configured to generate the correction image information according to the coloring information.

4. The liquid discharging apparatus according to claim 3 , further comprising
an image information input section to which recording image information is input,
the correction processing section being further configured to generate the correction image information by correcting the recording image information according to the coloring information.

5. A liquid discharging method for recording an image on a recording medium by discharging a liquid onto the recording medium using the liquid discharging apparatus according to claim 1 , the method comprising:
acquiring recording image information which is to be recorded on the recording medium;
acquiring coloring information for the recording medium which is supplied to the liquid discharging apparatus using the coloring information acquiring section;
generating liquid discharge control information based on the recording image information and the coloring information; and
discharging the liquid onto the recording medium using the liquid discharging section based on the liquid discharge control information.

6. The liquid discharging method according to claim 5 , wherein the generating of the liquid discharge control information includes
generating a correction look up table by correcting a look up table which converts the recording image information into liquid discharge control information, which corresponds to the recording image information, based on the coloring information, and
converting the recording image information into the liquid discharge control information according to the correction look up table.

7. The liquid discharging method according to claim 5 , wherein the generating of the liquid discharge control information includes
generating correction recording image information by correcting the recording image information based on the coloring information, and
generating the liquid discharge control information based on the correction recording image information.

8. The liquid discharging method according to claim 5 , wherein the generating of the liquid discharge control information includes
correcting the liquid discharge control information which corresponds to the recording image information based on the coloring information.
