## Abstract

When a user overlaps a region set for a picture examination and a region set for a data examination, the user is not notified that a print image examination is not performed on the overlap region. A printing system reads a printout, generates a scan image, performs a first examination to examine the printout based on the scan image and a correct image, and performs a second examination to examine data acquired from the printout based on data acquired from the scan image and correct data, and in a case where at least a first region to be examined by the first examination and a second region to be examined by the second examination are set in the correct image and the first region and the second region include an overlap region, the printing system provides a notification of the overlap of the first region and the second region.

## Claims

### Claim 1

A printing system comprising:
one or more controllers having one or more processors and one or more memories, the one or more controllers configured to cause the printing system to:
print an image on a recording sheet, the image including a variable region where an image printed on a first page and an image printed on a second page differ and a fixed region where an image printed on the first page and an image printed on the second page are the same;
read a printout printed by the printing and generate a scan image;
display a correct image including at least the fixed region on a display unit;
examine, as a first examination, the printout based on at least the fixed region of the scan image and the correct image;
examine, as a second examination, data acquired from the printout based on data acquired from an image printed in the variable region of the scan image and correct data;
set at least a first region to be examined by the first examination and a second region to be examined by the second examination in the correct image displayed on the display unit; and
provide, in a case where the first region and the second region include an overlap region, a notification of overlap of the first region and the second region.

### Claim 2 (depends on 1)

The printing system according to claim 1, wherein the overlap region of the first region and the second region is examined by the second examination and is not examined by the first examination.

### Claim 3 (depends on 1)

The printing system according to claim 1, wherein in a case where the first region and the second region include the overlap region during the setting of the first region and the second region, a notification of the overlap region is provided via a user interface (UI) screen via which the setting is performed.

### Claim 4 (depends on 1)

The printing system according to claim 1, wherein in a case where the setting of the first region and the second region is ended and the first region and the second region include one or more overlap regions, a pop-up notification of the overlap region is provided.

### Claim 5 (depends on 1)

The printing system according to claim 1, wherein the second examination is performed based on the correct data and data read from a character string or a barcode printed in the variable region.

### Claim 6 (depends on 1)

The printing system according to claim 1, wherein the first examination examines the printout based on a comparison between the generated scan image and the correct image corresponding to the scan image.

### Claim 7 (depends on 1)

The printing system according to claim 1, wherein the correct image includes the generated scan image.

### Claim 8 (depends on 1)

The printing system according to claim 1, wherein the correct image includes image data on which raster image processor (RIP) processing is performed.

### Claim 9 (depends on 1)

The printing system according to claim 1, wherein the printing system includes a printing apparatus configured to perform the printing an image on a recording sheet and an examination apparatus configured to perform the generating the scan image, display control to display the correct image, the setting of the first region and the second region, the first examination, the second examination, and the providing the notification.

### Claim 10

A printing system comprising:
a printing unit configured to print an image on a recording sheet, the image including a variable region where an image printed on a first page and an image printed on a second page differ and a fixed region where an image printed on the first page and an image printed on the second page are the same;
a generation unit configured to read a printout printed by the printing unit and generate a scan image;
a selection unit configured to select a page common mode in which a correct image including at least the fixed region is registered and a page individual mode in which a correct image for the first page and a correct image for the second page are registered;
a display control unit configured to display the correct image on a display unit;
a first examination unit configured to examine the printout based on the scan image and the correct image;
a second examination unit configured to examine data acquired from the printout based on data acquired from the scan image and correct data;
a setting unit configured to set at least a first region to be examined by the first examination unit and a second region to be examined by the second examination unit in the correct image; and
a notification unit configured to provide a notification of overlap of the first region and the second region,
wherein in a case where the first region and the second region include an overlap region and the page common mode is selected by the selection unit, the notification unit provides the notification of the overlap of the first region and the second region.

### Claim 11 (depends on 10)

The printing system according to claim 10, wherein in a case where the first region and the second region include the overlap region and the page individual mode is selected by the selection unit, the notification unit does not provide the notification of the overlap of the first region and the second region.

### Claim 12

An examination apparatus comprising:
a generation unit configured to read a printout and generate a scan image on a recording sheet, the printout including a printed image including a variable region where an element of an image printed on a first page and an element of an image printed on a second page differ and a fixed region where an element of an image printed on the first page and an element of an image printed on the second page are the same;
a display control unit configured to display a correct image including at least the fixed region on a display unit;
a first examination unit configured to examine the printout based on at least the fixed region of the scan image and the correct image;
a second examination unit configured to examine data written on the printout based on data read from an image printed in the variable region of the scan image and correct data;
a setting unit configured to set at least a first region to be examined by the first examination unit and a second region to be examined by the second examination unit in the correct image displayed on the display unit; and
a notification unit configured to provide, in a case where the first region and the second region include an overlap region, a notification of overlap of the first region and the second region.

### Claim 13

A method for controlling a printing system, the method comprising:
printing an image on a recording sheet, the image including a variable region where an image printed on a first page and an image printed on a second page differ and a fixed region where an image printed on the first page and an image printed on the second page are the same;
reading a printout printed by the printing and generating a scan image;
