Abstract

In an image processing apparatus, a condition for detecting a print position deviation on a print medium in a printed material is set. Based on the condition, data obtained by reading the print medium for the print position deviation is inspected. In the condition, in a case where a width of the print medium is larger than a readable width for reading the print medium, a settable range is small relative to a case where the width of the print medium is smaller than the readable width.

Claims (21)

1. An image processing apparatus, comprising:

a setting unit configured to set a condition for detecting a print position deviation on a print medium in a printed material; and

an inspection unit configured to inspect, based on the condition, data obtained by reading the print medium for the print position deviation,

wherein, in the condition, in a case where a width of the print medium is larger than a readable width for reading the print medium, a settable range is small relative to a case where the width of the print medium is smaller than the readable width.

2. The image processing apparatus according to claim 1 , further comprising an image reading unit,

wherein the inspection unit compares a reference image and an image subject to inspection obtained by reading the printed material by the image reading unit to perform the inspection.

3. The image processing apparatus according to claim 1 , wherein in a case where the width of the print medium is larger than the readable width for reading the print medium, the setting unit sets the settable range by changing a previously determined range.

4. The image processing apparatus according to claim 1 , wherein the settable range is expressed by a level of the print position deviation.

5. The image processing apparatus according to claim 4 , wherein in a case where the width of the print medium is larger than the readable width for reading the print medium, the setting unit sets the settable range so that a print position deviation corresponding to the level increases in size relative to a case where the width of the print medium is smaller than the readable width.

6. The image processing apparatus according to claim 1 , wherein the setting unit sets the settable range so that a magnitude of a print position deviation set to an inspection level allowing for detection of a minimum position deviation is a minimum detectable position deviation amount.

7. The image processing apparatus according to claim 1 , wherein the setting unit sets the condition independently vertically and horizontally relative to the print medium.

8. The image processing apparatus according to claim 1 , further comprising a conveyance position deviation amount acquisition unit configured to acquire a conveyance position deviation amount of the print medium,

wherein the setting unit sets the condition, based on the readable width for reading the print medium, the width of the print medium, and the conveyance position deviation amount.

9. A non-transitory computer-readable storage medium storing one or more programs including instructions, which when executed by a computer, cause the computer to perform operations comprising:

setting a condition for detecting a print position deviation on a print medium in a printed material; and

inspecting, based on the condition, data obtained by reading the print medium for the print position deviation,

wherein, in the condition, in a case where a width of the print medium is larger than a readable width for reading the print medium, a settable range is small relative to a case where the width of the print medium is smaller than the readable width.

10. An image processing method, comprising:

setting a condition for detecting a print position deviation on a print medium in a printed material; and

inspecting, based on the condition, data obtained by reading the print medium for the print position deviation,

wherein, in the condition, in a case where a width of the print medium is larger than a readable width for reading the print medium, a settable range is small relative to a case where the width of the print medium is smaller than the readable width.
