Title: Ryo Tsujii: Innovator in Ink Jet Technology
Introduction
Ryo Tsujii is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of ink jet technology, holding a total of 2 patents. His work focuses on improving the efficiency and quality of ink jet recording methods and apparatus.
Latest Patents
Tsujii's latest patents include an innovative ink jet recording method and an ink jet recording apparatus. The ink jet recording method is designed for recording images on a medium using an aqueous ink and a reaction liquid. This method utilizes a pigment that is dispersed through the action of a carboxylic acid group, along with a resin particle and a water-soluble organic solvent. Notably, the method ensures that the rate of increase in the particle size of the pigment is 8.0 times or more upon contact with the reaction liquid. Additionally, the recording medium absorbs a minimal amount of water, specifically 10 mL/m² or less, within the first 30 milliseconds of contact.
The ink jet recording apparatus complements this method by ejecting the aqueous ink from a recording head. The ink is heated to a specific temperature before application, and the recording medium is also heated to optimize the recording process. The relationships between the temperatures involved are carefully defined to enhance the performance of the ink jet technology.
