Title: Yisong Yu: Innovator in Lithographic Printing Technology

Introduction

Yisong Yu is a prominent inventor based in Vancouver, Canada. He has made significant contributions to the field of lithographic printing technology. With a total of 5 patents to his name, his work has advanced the capabilities and efficiency of printing processes.

Latest Patents

One of Yisong Yu's latest patents is a processless lithographic printing plate precursor. This innovation involves a radiation-sensitive medium that comprises hydrophilic polymer particles. These particles include a thermally softenable hydrophobic polymer, a hydrophilic polymer, and a bonding compound that can chemically bond to both types of polymers. The medium is designed to be aqueous-eluable when coated and dried, becoming hydrophobic when exposed to heat. This allows for the creation of a negative-working lithographic printing master that is irreversible and does not require a substrate of controlled hydrophilicity. The processless radiation-imageable lithographic printing precursor can be imaged using absorbed radiation, resulting in distinct hydrophobic and hydrophilic properties in different areas.
