Abstract

An ink jet printing method includes attaching an ink composition to a cloth by using a printer head which has a nozzle discharging the ink composition, a pressure chamber for imparting pressure to the ink composition to cause the nozzle to discharge the ink composition, and a connection portion connecting the pressure chamber and the nozzle, and in which a distance of the connection portion is 500 μm or more, the distance of the connection portion being from a portion of the pressure chamber where the ink flows out from a pressure chamber to the nozzle side to the nozzle, in which the ink composition includes the resin as a solid content in the amount of 10% by mass to 26% by mass with respect to the ink composition, the ratio of the total content of the organic solvent to the total content of the solid content of the resin is 0.3 or more, and a sum of the total content of the solid content of the resin and the total content of the organic solvent is 37% by mass or less with respect to the ink composition.

First claim

What is claimed is:

1 . An ink jet printing method comprising:
attaching an ink composition to a cloth by using a printer head which has a nozzle discharging the ink composition, a pressure chamber for imparting pressure to the ink composition to cause the nozzle to discharge the ink composition, and a connection portion connecting the pressure chamber and the nozzle, and in which a distance of the connection portion is 500 μm or more, the distance of the connection portion being from a portion of the pressure chamber where the ink flows out from a pressure chamber to the nozzle side to the nozzle, wherein the ink composition includes a resin and an organic solvent.

2 . The ink jet printing method according to claim 1 ,
wherein the ink composition includes the resin as a solid content in the amount of 3% by mass to 13% by mass with respect to the ink composition, the ratio of the total content of the organic solvent to the total content of the solid content of the resin is 0.7 or more, and a sum of the total content of the solid content of the resin and the total content of the organic solvent is 35% by mass or less with respect to the ink composition.

3 . The ink jet printing method according to claim 1 ,
wherein, in the attaching of the ink composition, the maximum mass is 30 ng or less per one ink droplet of the discharged ink composition.

4 . The ink jet printing method according to claim 1 ,
wherein, in the printer head, the total capacity of the pressure chamber per pressure chamber and the connection portion is 4200 pl to 6200 pl.

5 . The ink jet printing method according to claim 1 ,
wherein the capacity of the pressure chamber per pressure chamber is 3700 pl or less.

6 . The ink jet printing method according to claim 1 ,
wherein the printer head includes a communicating plate provided with a communicating hole which configures a part of the connection portion.

7 . The ink jet printing method according to claim 1 , further comprising:
attaching a reaction liquid including an aggregating agent for aggregating or thickening a component of the ink composition to the cloth.

8 . The ink jet printing method according to claim 1 ,
wherein the ink composition is a non-white ink composition including a non-white pigment.

9 . The ink jet printing method according to claim 1 ,
wherein the printer head includes a plurality of nozzles discharging the ink composition in a row, and the nozzle density in the row direction is 200 dpi or more.

10 . The ink jet printing method according to claim 1 ,
wherein the maximum ink attachment amount to the cloth is 40 mg/inch 2 or less.

11 . An ink jet printing method comprising:
attaching an ink composition to a cloth by using a printer head which has a nozzle discharging the ink composition, a pressure chamber for imparting pressure to the ink composition to cause the nozzle to discharge the ink composition, and a connection portion connecting the pressure chamber and the nozzle, and in which a distance of the connection portion is 500 μm or more, the distance of the connection portion being from a portion of the pressure chamber where the ink flows out from a pressure chamber to the nozzle side to the nozzle, wherein the ink composition includes the resin as a solid content in the amount of 10% by mass to 26% by mass with respect to the ink composition, the ratio of the total content of the organic solvent to the total content of the solid content of the resin is 0.3 or more, and a sum of the total content of the solid content of the resin and the total content of the organic solvent is 37% by mass or less with respect to the ink composition.

12 . The ink jet printing method according to claim 11 ,
wherein, in the attaching of the ink composition, the maximum mass is 30 ng or less per one ink droplet of the discharged ink composition.

13 . The ink jet printing method according to claim 11 ,
wherein, in the printer head, the total capacity of the pressure chamber per pressure chamber and the connection portion is 4200 pl to 6200 pl.

14 . The ink jet printing method according to claim 11 ,
wherein the capacity of the pressure chamber per pressure chamber is 3700 pl or less.

15 . The ink jet printing method according to claim 11 ,
wherein the printer head includes a communicating plate provided with a communicating hole which configures a part of the connection portion.

16 . The ink jet printing method according to claim 11 , further comprising:
attaching a reaction liquid including an aggregating agent for aggregating or thickening a component of the ink composition to the cloth.

17 . The ink jet printing method according to claim 11 ,
wherein the ink composition is a white ink composition including a white pigment.

18 . The ink jet printing method according to claim 11 ,
wherein the printer head includes a plurality of nozzles discharging the ink composition in a row, and the nozzle density in the row direction is 200 dpi or more.

19 . The ink jet printing method according to claim 11 ,
wherein the maximum ink attachment amount to the cloth is 100 mg/inch 2 or more.

20 . An ink jet printing apparatus for performing printing by the ink jet printing method of claim 1 .
