Abstract

According to the invention, there is provided a recording method which includes discharging and adhering a reaction liquid to an ink non-absorbable or ink low-absorbable recording medium in a form of a droplet, by using an ink jet method, the reaction liquid containing a reagent for aggregating or thickening of a colored ink composition, so as to have a content of 0.1 mol/kg to 0.9 mol/kg, and the reaction liquid having an adhering amount which is set to be equal to or smaller than 1.9 mg/inch 2 , and adhering a colored ink composition to the recording medium to which the reaction liquid has adhered. A period from when adhering of the reaction liquid is ended until adhering of the colored ink composition is started is within 30 seconds. A surface temperature of the recording medium from the adhering of the reaction liquid to the adhering of the colored ink composition is equal to or lower than 38° C.

First claim

What is claimed is:

1 . A recording method comprising:
discharging and adhering a reaction liquid to an ink non-absorbable or ink low-absorbable recording medium in a form of a droplet, by using an ink jet method, the reaction liquid containing a reagent for aggregating or thickening of a colored ink composition, so as to have a content of 0.1 mol/kg to 0.9 mol/kg, and the reaction liquid having an adhering amount which is set to be equal to or smaller than 1.9 mg/inch 2 , and adhering a colored ink composition to the recording medium to which the reaction liquid has adhered, wherein a period from when adhering of the reaction liquid is ended until adhering of the colored ink composition is started is within 30 seconds, and a surface temperature of the recording medium from the adhering of the reaction liquid to the adhering of the colored ink composition is equal to or lower than 38° C.

2 . The recording method according to claim 1 , wherein
a mass of the reaction liquid per droplet (1 dot) in the adhering of the reaction liquid is equal to or smaller than 10 ng/dot.

3 . The recording method according to claim 1 , wherein
resolution of droplets in the adhering of the reaction liquid is equal to or greater than 200×200 dpi.

4 . The recording method according to claim 1 , wherein
an adhering amount of the reagent in the adhering of the reaction liquid is equal to or smaller than 1000 nmol/inch 2 .

5 . The recording method according to claim 1 , wherein
a temperature of the recording medium from the adhering of the reaction liquid to the adhering of the colored ink composition is from 32° C. to 38° C.

6 . The recording method according to claim 1 , wherein
the colored ink composition contains a resin, and the resin includes a resin in which a volume of a calcium acetate aqueous solution of 0.085 mol/kg is from 0.1 mL to 7 mL, and the volume thereof being required for aggregating an aqueous solution containing a resin of 1 mass % or an aqueous dispersion liquid of 3 mL.

7 . The recording method according to claim 1 , wherein
regarding a water absorption rate of the recording medium, an absorbed water amount until 30 msec 1/2 elapses from when contact is started in a Bristow method is equal to or smaller than 10 mL/m 2 .

8 . The recording method according to claim 1 , wherein
at least one selected from a group consisting of a multivalent metal salt and an organic acid is contained as the reagent.

9 . The recording method according to claim 1 , wherein
an adhering amount of the reaction liquid is set to be from 0.3 mg/inch 2 to 1.9 mg/inch 2 in a recording region in which an adhering amount of the colored ink composition in the adhering of the colored ink composition is equal to or greater than 5 mg/inch 2 .

10 . A recording apparatus which performs the recording method according to claim 1 .

11 . A recording apparatus which performs the recording method according to claim 2 .

12 . A recording apparatus which performs the recording method according to claim 3 .

13 . A recording apparatus which performs the recording method according to claim 4 .

14 . A recording apparatus which performs the recording method according to claim 5 .

15 . A recording apparatus which performs the recording method according to claim 6 .

16 . A recording apparatus which performs the recording method according to claim 7 .

17 . A recording apparatus which performs the recording method according to claim 8 .

18 . A recording apparatus which performs the recording method according to claim 9 .
