Title: Innovations of Tetsuya Sakamoto in Thermal Recording Technology

Introduction

Tetsuya Sakamoto, an accomplished inventor based in Tokyo, Japan, has made significant contributions to the field of thermal recording technology. With a total of two patents to his name, Sakamoto’s work centers on innovating methods that enhance the quality and efficiency of color image reproduction.

Latest Patents

Sakamoto's most recent patents are centered around a multicolor sublimation type thermal recording method. This innovative process involves delivering pictorial image data for each color through a sophisticated methodology that includes color resolution applied to a manuscript using a color scanner. The data is then transferred from a sublimation transfer sheet to an image-receiving sheet, enabling the hard copy of a color image. The image data includes three primary colors—cyan, magenta, and yellow—along with black data derived from these primary colors. Sakamoto’s design also involves meticulous color and gradation corrections applied to the four color data before delivery to the sublimation transfer printer. By utilizing this technique, the primer ink is successfully transferred onto image-receiving paper, producing high-quality hard copies of color images.
