Title: Innovations of Yoshinori Honkawa

Introduction

Yoshinori Honkawa is a prominent inventor based in Fuchu, Japan. He has made significant contributions to the field of printing technology, holding a total of 12 patents. His work focuses on enhancing the efficiency and precision of offset printing machines.

Latest Patents

Honkawa's latest patents include a system for determining dampening water for an offset press. This innovative system utilizes a LED that radiates light onto a plate held on a plate cylinder upon receiving a radiation start signal. The system forms an irradiated area on the plate, where a photo diode senses the conventional catoptric light reflected from this area. The sensed signal represents the conventional catoptric light intensity, allowing a data processing unit to compute the dampening volume based on this signal. The dampening volume signal is then generated by a storage device.

Another notable patent involves an offset printing machine that features a sleeve with a tapered side surface, which is movable in the axial direction to a gripper shaft. This design allows for high precision in detecting the image position on the printing plate, eliminating errors caused by configuration discrepancies. The method enables the automatic feeding of the printing plate to the plate cylinder, ensuring that the image is parallel to the cylinder.
