Title: Kuniharu Okuda: Innovator in Image Recording Technology

Introduction

Kuniharu Okuda is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of image recording technology, holding a total of 3 patents. His innovative approaches have advanced the efficiency and quality of printing processes.

Latest Patents

One of Okuda's latest patents is an apparatus for and method of recording images. This image recording apparatus features a plurality of recording heads arranged in a staggered configuration. Adjacent recording heads have respective nozzles that eject ink droplets onto positions close to each other on a recording medium. For effective image recording, a correction area rate is calculated, which is less than the dot area rate of the input image. This method ensures that the amounts of ink droplets ejected from adjacent nozzles are limited, thereby suppressing unevenness in density caused by undesirable ink flow or bleeding at the boundaries between recording regions.

Another significant patent involves a method of presetting ink. In this process, ink supply is controlled during the first printing to achieve a measured printed density that is approximately equal to a first target density. This results in a uniform amount of ink remaining on the ink rollers after the first printing. In subsequent printing processes, a lower second target density is used, which stabilizes the early start of printing by facilitating a uniform distribution of ink.
