Abstract

An image forming system that is capable of forming an image onto a sheet on a basis of print image data including multiple image data items imposed in such a manner as to be suitable for middle-folding and saddle-stitching and outputting a booklet by performing middle-folding and saddle-stitching includes: a storing unit that stores beforehand, as an output-processing content table, an inclination direction of a compilation tray onto which a stack of sheets that is to be subjected to imposition processing for pages or a facing page of the booklet and the middle-folding and saddle-stitching is placed; and a processing unit that generates the print image data by acquiring information of the inclination direction of the compilation tray, referencing to the output-processing content table, and performing the imposition processing.

First claim

What is claimed is:

1. An image forming system that is capable of forming an image onto a sheet on a basis of print image data including a plurality of image data items imposed in such a manner as to be suitable for middle-folding and saddle-stitching and outputting a booklet by performing middle-folding and saddle-stitching, the image forming system comprising:
a compilation tray having a placement surface on which a plurality of sheets are stacked as a transport roller transports one sheet at a time after an image is formed on the one sheet;
a folding mechanism including a folding knife that is positioned and configured to project from a backside of the compilation tray to the placement surface of the compilation tray; and
a processor programmed to:
determine whether an inclination direction of the compilation tray is a first direction or a second direction, wherein the compilation tray inclined in the first direction is inclined toward an upstream side in a direction in which sheets are transported toward the compilation tray, and the compilation tray inclined in the second direction is inclined toward a downstream side in the direction in which the sheets are transported toward the compilation tray;
upon determining that the inclination direction of the compilation tray is the first direction, generate the print image data so that a first sheet, which is placed on the compilation tray first so as to contact the placement surface, has image for an innermost sheet in the booklet; and
upon determining that the inclination direction of the compilation tray is the second direction, generate the print image data in a different order so that the first sheet, which is placed on the compilation tray first so as to contact the placement surface, has image for an outermost sheet in the booklet.

2. The image forming system according to claim 1 ,
wherein, when a booklet having n pages (n is an integer of one or more) is output while the inclination direction of the compilation tray is the first direction, page n/2−2×i+2 and page n/2+2×i−1 are imposed on one surface of the ith sheet placed on the compilation tray, the one surface facing the upstream side in the direction in which the sheets are transported, and page n/2−2×i+1 and page n/2+2×i are imposed on another surface of the ith sheet placed on the compilation tray, the other surface facing the downstream side in the direction in which the sheets are transported.

3. The image forming system according to claim 2 ,
wherein the processor acquires information of the inclination direction of the compilation tray in accordance with a type of a post-processing apparatus that is actually included in the image forming system.

4. The image forming system according to claim 3 ,
wherein, when the information of the inclination direction of the compilation tray is not acquired, an imposition processing with reference to an output-processing content table is not performed.

5. The image forming system according to claim 2 , further comprising:
an input unit,
wherein the processor acquires information of the inclination direction of the compilation tray in accordance with an input from the input unit.

6. The image forming system according to claim 5 ,
wherein, when the information of the inclination direction of the compilation tray is not acquired, an imposition processing with reference to an output-processing content table is not performed.

7. The image forming system according to claim 1 ,
wherein, when a booklet having n pages (n is an integer of one or more) is output while the inclination direction of the compilation tray is the second direction, page 2×i and page n−2×i+1 are imposed on one surface of the ith sheet placed on the compilation tray, the one surface facing the upstream side in the direction in which the sheets are transported, and page 2×i−1 and page n−2×i+2 are imposed on another surface of the ith sheet placed on the compilation tray, the other surface facing the downstream side in the direction in which the sheets are transported.

8. The image forming system according to claim 7 ,
wherein the processor acquires information of the inclination direction of the compilation tray in accordance with a type of a post-processing apparatus that is actually included in the image forming system.

9. The image forming system according to claim 8 ,
wherein, when the information of the inclination direction of the compilation tray is not acquired, an imposition processing with reference to an output-processing content table is not performed.

10. The image forming system according to claim 7 , further comprising:
an input unit,
wherein the processor acquires information of the inclination direction of the compilation tray in accordance with an input from the input unit.

11. The image forming system according to claim 10 ,
wherein, when the information of the inclination direction of the compilation tray is not acquired, an imposition processing with reference to an output-processing content table is not performed.

12. The image forming system according to claim 1 ,
wherein the processor acquires information of the inclination direction of the compilation tray in accordance with a type of a post-processing apparatus that is actually included in the image forming system.

13. The image forming system according to claim 12 ,
wherein, when the information of the inclination direction of the compilation tray is not acquired, an imposition processing with reference to an output-processing content table is not performed.

14. The image forming system according to claim 1 , further comprising:
an input unit,
wherein the processor acquires information of the inclination direction of the compilation tray in accordance with an input from the input unit.

15. The image forming system according to claim 14 ,
wherein, when the information of the inclination direction of the compilation tray is not acquired, an imposition processing with reference to an output-processing content table is not performed.
