Claims

[Scope of Claim for Utility Model Registration] 1. An imaging camera connected to a microscope that magnifies the print of a printer composed of dots, and a video signal from this imaging camera that is converted into a digital signal as image data having gradations. an image memory to store, and an operation for reading out the contents of the image memory, binarizing the image data, measuring the position of a specific point of the print, and calculating a numerical value for characterizing the shape of the print based on the measured value. A printing quality inspection device characterized by comprising a processing device. 2. The printing quality inspection device as set forth in Claim 1 of the Utility Model Registration Claim, wherein the arithmetic processing device measures the area of each dot. 3. In the statement of either paragraph 1 or 2 of the claims for utility model registration, the arithmetic processing device is
A print quality inspection device characterized by measuring the gradation of each dot for each pixel. 4 Utility Model Registration Claims In any one of claims 1 to 3, the arithmetic processing device places a plurality of prints in the same field of view of an imaging camera, measures the distance to a specific point of the prints, and calculates the distance between the prints. A printing quality inspection device characterized by inspecting an array of. 5. In any of claims 1 to 4 of the claims for utility model registration, the arithmetic processing device detects a plurality of specific points of printing in the horizontal or vertical direction by moving a microscope in the horizontal or vertical direction. A print quality inspection device characterized by measuring the print quality and inspecting the arrangement of the prints in the same horizontal or vertical direction based on the measured values.
