Latest Patents

Wakui holds a patent for a halftone image generation method, which includes a threshold matrix generation method, a threshold matrix, a printing plate manufacturing method, and a printing plate. This patent describes a halftone image formed on a printing plate for letterpress printing. The minimum halftone dot consists of a square main cluster made up of 9 pixels, with four sub-clusters positioned around the main cluster. Each sub-cluster contacts only a vertex of the main cluster. The design allows for the formation of convex portions on the printing plate, which correspond to the minimum halftone dots. This innovative approach increases the strength of relief corresponding to the minimum halftone dot, thereby improving the reproduction of halftone images in printing.
