Abstract

A recording apparatus includes an ink application unit configured to apply ink to a transfer body, a first application unit configured to apply a first treatment liquid over an area on the transfer body, a second application unit configured to apply a second treatment liquid to the transfer body, a heating unit configured to heat the second treatment liquid applied to the transfer body, and a transfer unit configured to transfer the ink image, wherein a ratio of the second treatment liquid to the first treatment liquid on an outside of ink portion is determined according to the recording medium.

First claim

What is claimed is:

1 . A recording apparatus comprising:
an ink application unit configured to apply ink to a transfer body to form an ink image corresponding to an image to be formed on the transfer body; a first application unit configured to apply a first treatment liquid over an area from a portion on the transfer body to which the ink is applied, to an area outside of the ink applied portion, the first treatment liquid containing a component which acts on a component included in the ink and suppressing a movement of the ink on the transfer body through the action; a second application unit configured to apply a clear second treatment liquid to the transfer body, the second treatment liquid including a resin which becomes a membrane by heating; a heating unit configured to heat the second treatment liquid applied to the transfer body; and a transfer unit configured to transfer the ink image, the first treatment liquid at an area outside the ink image, and the second treatment liquid onto a recording medium, wherein in a case where the recording medium is a predetermined medium, the second application unit applies the second treatment liquid to the first treatment liquid on the area outside of the ink applied portion in a predetermined ratio, and in a case where permeability of the first treatment liquid is higher in the recording medium than in the predetermined medium, the second application unit applies the second treatment liquid to the first treatment liquid on the area outside of the ink applied portion in a ratio lower than the predetermined ratio or does not apply the second treatment liquid.

2 . The recording apparatus according to claim 1 , wherein the predetermined medium is cast-coated paper or vapor-deposition paper, and the recording medium which is higher than the predetermined recording medium in the permeability with respect to the first treatment liquid is, plain paper or gloss paper.

3 . The recording apparatus according to claim 1 , the first application unit applies the first treatment liquid over an entire area on the transfer body where the ink image is to be formed.

4 . The recording apparatus according to claim 3 , wherein in a case where the recording medium is the predetermined medium, the second application unit applies the second treatment liquid over an entire area on the transfer body to which the first treatment liquid is applied.

5 . The recording apparatus according to claim 3 , wherein in a case where the permeability of the first treatment liquid is higher in the recording medium than in the predetermined medium, the second application unit applies the second treatment liquid only to the portion on the transfer body to which the ink is applied, or only to the portion on the transfer body to which the ink is applied and a vicinity of the ink applied portion based on information representing the portion to which the ink is applied based on image data representing the image.

6 . The recording apparatus according to claim 1 , wherein the first application unit applies the first treatment liquid to the transfer body according to data obtained by executing bold processing on data corresponding to the ink image based on image data representing the image.

7 . The recording apparatus according to claim 1 , wherein after the first application unit applies the first treatment liquid to the transfer body, the ink application unit forms the ink image on the first treatment liquid on the transfer body.

8 . The recording apparatus according to claim 1 , further comprising:
an obtaining unit configured to obtain information about a type of the recording medium, wherein the second application unit applies the second treatment liquid to the transfer body based on the information obtained by the obtaining unit.

9 . A recording apparatus comprising:
an ink application unit configured to apply ink to a recording medium to form an ink image corresponding to an image to be formed on the recording medium; a first application unit configured to apply a first treatment liquid over an area from a portion on the recording medium to which the ink is applied, to an area outside of the ink applied portion, the first treatment liquid containing a component which acts on a component included in the ink and suppressing a movement of the ink on the recording medium through the action; a second application unit configured to apply a clear second treatment liquid to the recording medium, the second treatment liquid including a resin which becomes a membrane by heating; and a heating unit configured to heat the second treatment liquid applied to the recording medium, wherein in a case where the recording medium is a predetermined medium, the second application unit applies the second treatment liquid to the first treatment liquid on the area outside of the ink applied portion in a predetermined ratio, and in a case where permeability of the first treatment liquid is higher in the recording medium than in the predetermined medium, the second application unit applies the second treatment liquid to the first treatment liquid on the area outside of the ink applied portion in a ratio lower than the predetermined ratio or does not apply the second treatment liquid.

10 . A recording method comprising:
applying ink to a transfer body to form an ink image corresponding to an image to be formed on the transfer body; applying a first treatment liquid over an area from a portion on the transfer body to which the ink is applied, to an area outside of the ink applied portion, the first treatment liquid containing a component which acts on a component included in the ink and suppressing a movement of the ink on the transfer body through the action; applying a clear second treatment liquid to the transfer body, the second treatment liquid including a resin which becomes a membrane by heating; heating the second treatment liquid applied to the transfer body; and transferring the ink image, the first treatment liquid at an area outside the ink image, and the second treatment liquid to a recording medium, wherein in a case where the recording medium is a predetermined medium, the second treatment liquid is applied to the first treatment liquid on the area outside of the ink applied portion in a predetermined ratio, and in a case where permeability of the first treatment liquid is higher in the recording medium than in the predetermined medium, the second treatment liquid is applied to the first treatment liquid on the area outside of the ink applied portion in a ratio lower than the predetermined ratio, or is not applied to the first treatment liquid.

11 . The recording method according to claim 10 , wherein the predetermined medium is cast-coated paper or vapor-deposition paper, and the recording medium which is higher than the predetermined recording medium in the permeability with respect to the first treatment liquid is, plain paper or gloss paper.

12 . The recording method according to claim 10 , in the applying a first treatment liquid, the first treatment liquid is applied over an entire area on the transfer body where the ink image is to be formed.

13 . The recording method according to claim 12 , wherein in a case where the recording medium is the predetermined medium, the second treatment liquid is applied over an entire area on the transfer body to which the first treatment liquid is applied.

14 . The recording method according to claim 12 , wherein in a case where the permeability of the first treatment liquid is higher in the recording medium than in the predetermined medium, the second treatment liquid
