Title: The Innovations of Inventor Shigeru Iguchi
Introduction
Shigeru Iguchi is a notable inventor based in Nagaokakyo, Japan, recognized for his outstanding contributions to the field of lithographic printing technology. With a total of nine patents to his name, Iguchi has made significant strides in developing more efficient and effective methods for producing lithographic printing plates.
Latest Patents
Among his latest innovations, Iguchi has patented a method for making lithographic printing plates that feature high sensitivity and high printing endurance. This invention emphasizes the use of a photographic photosensitive material, which includes a support and an unfogged internal latent image type silver halide emulsion layer that is subjected to scanner-exposing. Following this procedure, the exposed material undergoes non-tanning development in the presence of a nucleating agent, and the silver halide portion of the emulsion layer is treated to enhance its oleophilizing properties.
Another significant patent of his focuses on improving the water retention of lithographic printing plate materials. This innovation notably increases the printing endurance of plates produced via the silver complex diffusion transfer process. Iguchi's solution effectively reduces staining during printing by incorporating specific layers with heavy metal nuclei for physical development and relevant water-soluble synthetic polymers.
