Abstract

A printing system includes a control unit configured to control an image forming unit to form an image on a sheet based on print setting information included in received job setting information, control a post-processing unit to execute a post-process corresponding to a designated type, and control a creasing unit.

First claim

What is claimed is:

1. An image forming system comprising:
an image forming unit configured to form an image on a sheet;
a creasing unit configured to crease the sheet on which the image is formed by the image forming unit, the creasing unit being arranged downstream of the image forming unit in a sheet conveyance direction;
a post-processing unit configured to execute one of post-processes for the sheet on which the image has been formed by the image forming unit and which has been conveyed through the creasing unit, the post-processing unit being arranged downstream of the creasing unit in the sheet conveyance direction;
a receiving unit configured to receive job setting information, wherein the job setting information includes at least print setting information which is a designation of single-sided-printing or double-sided-printing, post-processing setting information for designating a type of a post-process, and creasing setting information for creasing; and
a control unit configured to control the image forming unit, the creasing unit, and the post-processing unit,
wherein the control unit:
controls the image forming unit to form an image on the sheet based on the print setting information included in the job setting information received by the receiving unit,
controls the post-processing unit to execute the post-process corresponding to the type designated by the post-processing setting information included in the job setting information received by the receiving unit, and
controls the creasing unit to determine a position for creasing the sheet and perform creasing on the determined position, based on the post-processing setting information and the creasing setting information included in the job setting information received by the receiving unit.

2. The system according to claim 1 , wherein
the creasing unit comprises a creasing blade, and
the creasing unit creases by pressing the creasing blade against the sheet.

3. The system according to claim 1 , wherein the post-processing unit is a case binding unit.

4. The system according to claim 1 , wherein the post-processing unit is a saddle-stitching unit.

5. The system according to claim 1 , wherein
the receiving unit receives image data in addition to the job setting information, and
the image forming unit forms an image on the sheet based on the image data.

6. The system according to claim 1 , wherein the creasing setting information is a setting about whether to make a crease.

7. An image forming system comprising:
an image forming unit configured to form an image on a sheet;
a creasing unit configured to crease the sheet on which the image is formed by the image forming unit, the creasing unit being arranged downstream of the image forming unit in a sheet conveyance direction;
a post-processing unit configured to execute one of post-processes for the sheet on which the image has been formed by the image forming unit and which has been conveyed through the creasing unit, the post-processing unit being arranged downstream of the creasing unit in the sheet conveyance direction;
a receiving unit configured to receive job setting information, wherein the job setting information includes at least print setting information for printing, post-processing setting information for designating a type of a post-process, and creasing setting information for creasing; and
a control unit configured to control the image forming unit, the creasing unit, and the post-processing unit,
wherein the control unit:
controls the image forming unit to form an image on the sheet based on the print setting information included in the job setting information received by the receiving unit,
controls the post-processing unit to execute the post-process corresponding to the type designated by the post-processing setting information included in the job setting information received by the receiving unit, and
controls the creasing unit to determine a position for creasing the sheet and perform creasing on the determined position, based on the post-processing setting information and the creasing setting information included in the job setting information received by the receiving unit, and

wherein the position for creasing the sheet is a hinge position of a cover of a bookbinding product generated by the post-processing unit.

8. An image forming system comprising:
an image forming unit configured to form an image on a sheet;
a creasing unit configured to crease the sheet on which the image is formed by the image forming unit, the creasing unit being arranged downstream of the image forming unit in a sheet conveyance direction;
a post-processing unit configured to execute one of post-processes for the sheet on which the image has been formed by the image forming unit and which has been conveyed through the creasing unit, the post-processing unit being arranged downstream of the creasing unit in the sheet conveyance direction;
a receiving unit configured to receive job setting information, wherein the job setting information includes at least print setting information for printing, post-processing setting information for designating a type of a post-process, creasing setting information for creasing, and information about thickness of the sheet; and
a control unit configured to control the image forming unit, the creasing unit, and the post-processing unit,
wherein the control unit:
controls the image forming unit to form an image on the sheet based on the print setting information included in the job setting information received by the receiving unit,
controls the post-processing unit to execute the post-process corresponding to the type designated by the post-processing setting information included in the job setting information received by the receiving unit, and
controls the creasing unit to determine a position for creasing the sheet and perform creasing on the determined position, based on the post-processing setting information and the creasing setting information included in the job setting information received by the receiving unit, and

wherein the creasing unit sets a pressure used when creasing the sheet based on the information about thickness of the sheet included in the job setting information.

9. An image forming apparatus comprising:
a receiving unit configured to receive job setting information, wherein the job setting information includes at least print setting information which is a designation of single-sided-printing or double-sided-printing, post-processing setting information for designating a type of a post-process, and creasing setting information for creasing;
an image forming unit configured to form an image on a sheet; and
a control unit configured to:
instruct the image forming unit to form an image on the sheet based on the print setting information included in the job setting information received by the receiving unit,
instruct a creasing apparatus to crease the sheet on which an image is formed by the image forming unit based on the creasing setting information included in the job setting information received by the receiving unit, wherein the creasing apparatus is arranged downstream of the image forming apparatus in a sheet conveyance direction, and
instruct a post-processing apparatus to execute the post-process corresponding to the type designated by the post-processing setting information included in the job setting information received by the receiving unit, wherein the post-processing apparatus is configured to execute one of post-processes for the sheet on which the image has been formed by the image forming unit and which has been conveyed through the creasing apparatus, and is arranged downstream of the creasing apparatus in the
