  • Patent number: 10775317
    Abstract: Provided are a printed matter inspection device and a printed matter inspection method for appropriately determining visibility of a streaky concentration defect, regardless of the size of a variation of pixel values of an image. A printed matter inspection device determines visibility of a streak from a basic streak intensity that is an intensity of the streak detected from a printed matter, color information and frequency feature information on a streak near-field area that is continuous from an area of the streak and has a variation of image feature amounts that is within a predetermined first range, and frequency feature information on an outer peripheral area that is in contact with the streak near-field area, and determines whether the quality of the printed matter is good or not on the basis of at least the visibility.

  • Patent number: 10564110
    Abstract: Provided are a printing result inspection apparatus, a method, and a program capable of determining a printing defect caused by a printing step and a printing paper defect caused by printing paper by reading the printing paper once. A defect determination unit determines whether defected regions extracted from a non-image region are the printing defect or the printing paper defect based on a density change amount and a color, and an image feature amount of a defected region determined as the printing paper defect in the non-image region is stored in paper defect information and is accumulated in a paper defect information storage unit. Next, the defect determination unit determines whether defected regions extracted from image regions are the printing defect or the printing paper defect based on the paper defect information.

  • Patent number: 9174427
    Abstract: On a printing relief plate, which is produced by a printing relief plate producing apparatus and a printing relief plate producing method, convexities and detecting portions are set to be lower than a solid area of the printing relief plate. In the event that a detecting portion image and a solid area image are printed on a print medium using the printing relief plate by a printing apparatus and by carrying out a printing method, in a printing pressure determining apparatus and a printing pressure determining method, it is determined whether a printing pressure is an appropriate printing pressure or not by comparing an optical density of the detecting portion image and an optical density of the solid area image.
