Abstract

An image forming apparatus determines whether crease processing at a plurality of portions set on the sheet includes crease processing on two, front and back surfaces of the sheet; determines, if it is determined that crease processing includes crease processing on the two surfaces of the sheet, whether a connected post-processing apparatus that performs crease processing on a sheet can perform crease processing on the two, front and back surfaces of the sheet by one feeding; and controls, if it is determined that the connected post-processing apparatus cannot perform crease processing on the two surfaces by one feeding, to change, to one of the front and back surfaces of the sheet based on attribute information of the sheet, a surface to be processed in crease processing at the plurality of portions.

First claim

What is claimed is:

1. A system for creasing a sheet, the system comprising:
an image forming unit configured to form an image on a sheet;
a creasing unit configured to crease the sheet supplied from the image forming unit;
an input unit configured to input, based on a user instruction, position information indicating a creasing position of the sheet and surface information indicating a creasing surface of the sheet;
a control unit configured to control the image forming unit to form the image on the sheet and control the creasing unit to crease the sheet, based on a print job to which the position information and the surface information input by the input unit are set; and
a display unit configured to display a preview screen corresponding to the position information and the surface information input by the input unit before generating the print job,
wherein, in the preview screen, the display unit displays the creasing position of the sheet in a first display form in a case where the creasing surface of the sheet is a front surface of the sheet, and displays the creasing position of the sheet in a second display form different from the first display form in a case where the creasing surface of the sheet is a back surface of the sheet.

2. The system according to claim 1 , wherein, in the preview screen, the display unit displays the creasing position of the sheet based on the position information input by the input unit.

3. The system according to claim 1 , wherein the first display form is a solid-line form, and the second display form is a broken-line form.

4. The system according to claim 1 , wherein, in the preview screen, the display unit displays a folding method corresponding to the creasing position input by the input unit.

5. The system according to claim 4 , wherein the folding method is a mountain fold or a valley fold.

6. The system according to claim 1 , wherein the creasing unit is configured to crease the sheet at a plurality of creasing positions including a first creasing position on a first surface of the sheet and a second creasing position on a second surface of the sheet opposite to the first surface.

7. The system according to claim 1 , wherein the creasing unit creases the sheet in a direction perpendicular to a conveyance direction of the sheet.

8. The system according to claim 1 , wherein the system includes an image forming apparatus comprising the image forming unit and the creasing unit, and a print server comprising the input unit and the display unit.

9. A control apparatus for controlling an image forming apparatus and a creasing apparatus, the control apparatus comprising:
an input unit configured to input, based on a user instruction, position information indicating a creasing position of a sheet and surface information indicating a creasing surface of the sheet;
a control unit configured to control the image forming apparatus to form an image on the sheet and control the creasing apparatus to crease the sheet, based on a print job to which the position information and the surface information input by the input unit are set; and
a display unit configured to display a preview screen corresponding to the position information and the surface information input by the input unit before generating the print job,
wherein, in the preview screen, the display unit displays the creasing position of the sheet in a first display form in a case where the creasing surface of the sheet is a front surface of the sheet, and displays the creasing position of the sheet in a second display form different from the first display form in a case where the creasing surface of the sheet is a back surface of the sheet.

10. A non-transitory computer-readable medium storing a program for controlling a computer to function as:
an input unit configured to input, based on a user instruction, position information indicating a creasing position of a sheet and surface information indicating a creasing surface of the sheet;
a control unit configured to control an image forming apparatus to form an image on the sheet and control a creasing apparatus to crease the sheet, based on a print job to which the position information and the surface information input by the input unit are set; and
a display unit configured to display a preview screen corresponding to the position information and the surface information input by the input unit before generating the print job,
wherein, in the preview screen, the display unit displays the creasing position of the sheet in a first display form in a case where the creasing surface of the sheet is a front surface of the sheet, and displays the creasing position of the sheet in a second display form different from the first display form in a case where the creasing surface of the sheet is a back surface of the sheet.
