Abstract

A recording method according to an embodiment of the present disclosure is a recording method to perform recording on a recording medium in a manner such that while a relative position between an ink jet head and the recording medium is transferred, a scan to eject an ink from the ink jet head so as to be adhered to the recording medium is performed a plurality of times for the recording. The method described above includes a step of adhering a treatment liquid containing an aggregating agent to the recording medium; a step of ejecting a color ink composition containing a colorant from the ink jet head so as to be adhered to the recording medium; and a step of ejecting a clear ink composition containing a resin from the ink jet head so as to be adhered to the recording medium. In the recording method described above, the color ink composition is adhered to the same scan region by performing the scan at least two times, the clear ink composition is adhered by the same scan as a final scan of the at least two scans to a scan region of the recording medium to which the color ink composition is adhered, and an adhesion amount of the clear ink composition adhered by the final scan in the region to which the color ink composition and the clear ink composition are adhered is 80 percent by mass or more of a total adhesion amount of the clear ink composition in the region.

First claim

What is claimed is:

1 . A recording method to perform recording on a recording medium in a manner such that while a relative position between an ink jet head and the recording medium is transferred, a scan to eject an ink from the ink jet head so as to be adhered to the recording medium is performed a plurality of times for the recording, the method comprising:
adhering a treatment liquid containing an aggregating agent to the recording medium; ejecting a color ink composition containing a colorant from the ink jet head so as to be adhered to the recording medium; and ejecting a clear ink composition containing a resin from the ink jet head so as to be adhered to the recording medium, wherein the color ink composition is adhered to the same scan region by performing the scan at least two times, the clear ink composition is adhered by the same scan as a final scan of the at least two scans to a scan region of the recording medium to which the color ink composition is adhered, and an adhesion amount of the clear ink composition adhered by the final scan in the region to which the color ink composition and the clear ink composition are adhered is 80 percent by mass or more of a total adhesion amount of the clear ink composition in the region.

2 . The recording method according to claim 1 ,
wherein a viscosity increase rate of the clear ink composition obtained by mixing the clear ink composition and the treatment liquid at a mass rate of 10:1, respectively, is higher than a viscosity increase rate of the color ink composition obtained by mixing the color ink composition and the treatment liquid at a mass rate of 10:1, respectively.

3 . The recording method according to claim 1 ,
wherein in an area in which an adhesion amount of the color ink composition is largest in the region to which the color ink composition and the clear ink composition are adhered, the total adhesion amount of the clear ink composition is 5 to 70 percent by mass with respect to a total adhesion amount of the color ink composition.

4 . The recording method according to claim 1 ,
wherein in the ejecting the color ink composition, the recording medium has a surface temperature of 45° C. or less.

5 . The recording method according to claim 1 ,
wherein in the region to which the color ink composition and the clear ink composition are adhered, the adhesion amount of the clear ink composition adhered by the final scan is 90 percent by mass or more of the total adhesion amount of the clear ink composition.

6 . The recording method according to claim 1 ,
Wherein a viscosity increase rate of the clear ink composition obtained by mixing the clear ink composition and the treatment liquid at a mass rate of 10:1, respectively, is 5 times or more.

7 . The recording method according to claim 1 ,
wherein the color ink composition is adhered to the same scan region by performing the scan 5 times or less.

8 . The recording method according to claim 1 ,
wherein the recording medium is a low-absorbing recording medium or a non-absorbing recording medium.

9 . A recording apparatus to perform recording using the recording method according to claim 1 , the apparatus comprising:
the color ink composition; the clear ink composition; and the ink jet head.
