Title: Masaru Ohnishi: Pioneering Innovations in Printing Technology

Introduction:

Masaru Ohnishi, a highly accomplished inventor hailing from Nagano, Japan, has emerged as a leading figure in the realm of printing technology. With an impressive portfolio of 103 patents, Ohnishi has made substantial contributions to the field, particularly in the areas of liquid ejecting apparatus, printing methods, and powdering techniques. This article delves into his recent patents and highlights his affiliation with MIMAKI ENGINEERING COMPANY, LTD., as well as the collaborative efforts with his esteemed colleagues, Akifumi Seki and Kazuya Nozaki.

Patent 1: Liquid Ejecting Apparatus, Liquid Ejecting Method, and Ink

Ohnishi's liquid ejecting apparatus patent revolutionizes the printing process, effectively enhancing the strength of ink after fixation. The apparatus, designed for ink ejection using the inkjet method, includes an inkjet head equipped with a specialized nozzle. The ink itself contains resin particles, allowing for efficient passage through the nozzle. These particles contain fibrous substances, such as cellulose fibers, further enhancing the ink's qualities.

Patent 2: Printing Apparatus, Printing Method, Powdering Apparatus, and Powdering Method

In this patent, Ohnishi addresses the crucial issue of powdering printed surfaces. The printing apparatus comprises an ink ejection component that prints on the medium and a powdering unit responsible for applying powder to the same surface. The powdering unit involves a liquid application device that applies a powder-containing liquid, consisting of powder and a solvent, to the medium. An energy ray emitting portion subsequently irradiates the powder-containing liquid, causing the solvent to evaporate and effectively bind the powder to the medium. Notably, the powder-containing liquid generates heat when exposed to energy rays, facilitating optimal powder adhesion.
