  • Patent number: 11027538
    Abstract: In a register error detection device, an image capturing unit captures an image of two first register marks of a first color printed on a substrate by a first plate cylinder of a rotary printing press and a second register mark of a second color printed on the substrate by a second plate cylinder of the rotary printing press. A calculation unit calculates a register error based on the number of pixels between a reference position located between the two first register marks and a comparison position that is based on the second register mark in the image captured by the image capturing unit.

  • Patent number: 10776677
    Abstract: In a control device which controls a printing press, a capturing unit captures an inspection target object printed on a target printed material by the printing press, and outputs RGB values of each pixel of a captured image. The converter specifies a pixel with respectively equal RGB values and a pixel with respectively approximating RGB values as pixels in the grayscale area in the image, and converts the RGB values of each pixel other than the grayscale area into HSV values. An extractor extracts a pixel of an extraction target color from the image based on the RGB values in a case of the pixel in the grayscale area, and the HSV values in a case of the pixel other than the grayscale area. The controller controls the printing press to correct the print misalignment based on the pixels of the extraction target color extracted by the extractor.
