Abstract

A recording apparatus includes a recording unit configured to form an ink image on a transfer body, a conveying unit configured to convey a recording medium, a transfer unit figured to transfer the ink image from the transfer body to the recording medium conveyed by the conveying unit, a reading unit configured to read the recording medium having the ink image transferred thereto, and a post-processing unit configured to apply a pressure to the recording medium having the ink image transferred thereto to perform post-processing for improving a gloss of the ink image on the recording medium. The post-processing unit applies a pressure to a recording medium not to be read by the reading unit, and applies to a recording medium to be read by the reading unit no pressure or a lower pressure than the pressure applied to the recording medium not to be read.

First claim

What is claimed is:

1 . A recording apparatus comprising:
a transfer body configured to travel through an ink image forming region and a transfer region; a recording unit configured to eject ink onto the transfer body in the ink image forming region to form an ink image on the transfer body; a conveying unit configured to convey a recording medium; a transfer unit configured to transfer the ink image from the transfer body to the recording medium conveyed by the conveying unit; a reading unit configured to read the recording medium having the ink image transferred thereto; and a post-processing unit configured to apply a pressure to the recording medium having the ink image transferred thereto to perform post-processing for improving a gloss of the ink image on the recording medium, wherein the post-processing unit applies a pressure to a recording medium not to be read by the reading unit, and a recording medium to be read by the reading unit is read by the reading unit under no pressure applied by the post-processing unit or under a lower pressure than the pressure applied to the recording medium not to be read by the reading unit.

2 . The recording apparatus according to claim 1 , wherein
the post-processing unit applies no pressure to the recording medium be read by the reading unit.

3 . The recording apparatus according to claim 1 , wherein
the post-processing unit applies, to the recording medium to be read by the reading unit, a lower pressure than the pressure applied to the recording medium not to be read by the reading unit.

4 . The recording apparatus according to claim 1 , wherein
the post-processing unit applies a pressure to the recording medium to be read by the reading unit for a shorter time than to the recording medium not to be read by the reading unit.

5 . The recording apparatus according to claim 1 , wherein
the recording medium to be read by the reading unit comprises a maintenance pattern that is used for maintenance of the recording unit.

6 . The recording apparatus according to claim 5 , wherein
the recording unit includes a plurality of nozzles each configured to eject ink, the maintenance pattern is formed by ejection of ink from each of the plurality of nozzles, and the recording apparatus further comprises a correction unit configured to correct image data on the basis of a result of reading the maintenance pattern by the reading unit to reduce image density variations in a direction in which the plurality of nozzles are arranged.

7 . The recording apparatus according to claim 1 , wherein the post-processing unit applies a pressure to the recording medium having the ink image transferred thereto by using a roller.

8 . The recording apparatus according to claim 1 , wherein the post-processing unit heats the recording medium having the ink image transferred thereto while applying a pressure to the recording medium having the ink image transferred thereto, and then cools the heated recording medium.

9 . A recording method using a recording apparatus including a transfer body configured to travel through an ink image forming region and a transfer region, a recording unit configured to eject ink onto the transfer body in the ink image forming region to form an ink image on the transfer body, a conveying unit configured to convey a recording medium, and a transfer unit configured to transfer the ink image from the transfer body to the recording medium conveyed by the conveying unit, the recording method comprising:
a reading step of reading the recording medium having the ink image transferred thereto; and a pressure-applying step of applying a pressure to the recording medium having the ink image transferred thereto to perform post-processing for improving a gloss of the ink image on the recording medium, wherein a pressure is applied to a recording medium not to be read in the pressure-applying step, and a recording medium to be read is read under no pressure applied in the pressure-applying step or under a lower pressure than the pressure applied to the recording medium not to be read in the pressure-applying step.
