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 recording unit configured to apply ink onto a recording medium to form an ink image on the recording medium;
a post-processing unit configured to apply a pressure to the recording medium having an ink image formed by the recording unit to perform post-processing for improving a gloss of the ink image on the recording medium; and
a reading unit configured to read a recording medium having an ink image,
wherein
the post-processing unit applies a pressure to a recording medium, having the ink image formed by the recording unit, not to be read by the reading unit, and
the post-processing unit applies no pressure to the recording medium, having an ink image formed by the recording unit, to be read by the reading unit.

2. 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.

3. The recording apparatus according to claim 2 , 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.

4. The recording apparatus according to claim 1 , further comprising:
a recording unit including a transfer body configured to hold an ink image formed by ink; and
a transfer unit configured to transfer the ink image from the transfer body to the recording medium conveyed by a conveying unit.

5. The recording apparatus according to claim 4 , wherein the post-processing unit applies a pressure to the recording medium having the ink image transferred thereto by using a roller.

6. The recording apparatus according to claim 4 , 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.

7. A recording method using a recording apparatus including a recording unit configured to apply ink onto a recording medium to form an ink image, a post-processing unit configured to apply a pressure to the recording medium, and a reading unit configured to read a recording medium, the recording method comprising:
a pressure-applying step of applying a pressure to the recording medium having the ink image, to perform post-processing for improving a gloss of the ink image on the recording medium by the post-processing unit,
an outputting step of outputting the recording medium on which the post-processing is performed without reading the recording medium by the reading unit to which the pressure has been applied in the pressure-applying step,
wherein the recording method further comprises:
a recording step of recording an image onto a recording medium by applying ink onto the recording medium by the recording unit; and
a reading step of reading the recording medium, having the image, to which the post-processing unit has applied no pressure for the post-processing, by the reading unit.

8. A recording apparatus comprising:
a recording unit configured to apply ink onto a recording medium to form an ink image on the recording medium;
a post-processing unit configured to apply a pressure to the recording medium, having an ink image formed by the recording unit to perform post-processing for improving a gloss of the ink image on the recording medium; and
a reading unit configured to read a recording medium having an ink image,
wherein
the post-processing unit applies a pressure to a recording medium, having the ink image formed by the recording unit, not to be read by the reading unit, and
the post-processing unit applies no pressure to the recording medium, having an ink image formed by the recording unit, to be read by the reading unit.

9. A recording apparatus comprising:
a recording unit configured to apply ink onto a recording medium to form an ink image on the recording medium;
a post-processing unit configured to apply a pressure to the recording medium, having an ink image formed by the recording unit to perform post-processing for improving a gloss of the ink image on the recording medium; and
a reading unit configured to read a recording medium having an ink image,
wherein
the post-processing unit applies a pressure to a recording medium, having the ink image formed by the recording unit, not to be read by the reading unit, and
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.

10. A recording apparatus comprising:
a recording unit configured to apply ink onto a recording medium to form an ink image on the recording medium;
a post-processing unit configured to apply a pressure to the recording medium, having an ink image formed by the recording unit to perform post-processing for improving a gloss of the ink image on the recording medium; and
a reading unit configured to read a recording medium having an ink image,
wherein
the post-processing unit applies a pressure to a recording medium, having the ink image formed by the recording unit, not to be read by the reading unit, and
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.
