Abstract
The present invention is related to an inspection apparatus reads a printed material; sets a setting relating to check inspection data for checking data formed on a printed material; derives data defined by a predetermined rule according to setting content set in the setting and generating check inspection data for a plurality of sections in a printed material; and detects a defect in an inspection target printed material by comparing data read in the reading from the inspection target printed material and the corresponding check inspection data generated in the generating.
Claims17
An inspection apparatus comprising:
- one or more memory devices that store instructions;
- and
- one or more processors that execute the instructions to:
- obtain target data from a scanner reading an inspection target printed material;
- set a sequential number inspection, including setting a starting number, an ascending or descending order, and an offset indicating an increase or decrease in a numerical value of the sequential number inspection for an inspecting number formed on the inspection target printed material;
- generate reference data in accordance with the set starting number, the set ascending or descending order, and the set offset;
- and
- detect a defect in the inspection target printed material by comparing the obtained target data and the generated reference data.
A control method for an inspection apparatus comprising:
- obtaining target data from a scanner reading an inspection target printed material;
- setting a sequential number inspection, including setting a starting number, an ascending or descending order, and an offset indicating an increase or decrease in a numerical value of the sequential number inspection for an inspecting number formed on the inspection target printed material;
- generating reference data in accordance with the set starting number, the set ascending or descending order, and the set offset;
- and
- detecting a defect in the inspection target printed material by comparing the obtained target data and the generated reference data.
A non-transitory computer-readable storage medium storing a computer program executable by a computer to execute a control method comprising:
- obtaining target data from a scanner reading an inspection target printed material;
- setting a sequential number inspection, including setting a starting number, an ascending or descending order, and an offset indicating an increase or decrease in a numerical value of the sequential number inspection for an inspecting number formed on the inspection target printed material;
- generating reference data in accordance with the set starting number, the set ascending or descending order, and the set offset;
- and
- detecting a defect in the inspection target printed material by comparing the obtained target data and the generated reference data.
