Title: Innovations by Joshua M Rosenheck: Advancements in Printing Ink Technologies

Introduction

Joshua M Rosenheck, an inventive mind based in Concord, OH, has made significant contributions to the field of printing technology. With a total of two patents to his name, he has been at the forefront of developing solutions that enhance the printing process and improve ink properties.

Latest Patents

One of Rosenheck's latest patents is focused on the creation of shear resistant printing ink vehicles. This innovation details a method for producing gelled ink resins that showcase improved properties, such as lower viscosity under low shear conditions and minimal viscosity decrease as shear increases. By mixing a rosin-based or hydrocarbon-based resin with an organic solvent and introducing a polyamine reactant, a robust covalently cross-linked gelled resin is created. This resin exhibits resistance to viscosity breakdown under high shear conditions, making it suitable for direct use in ink compositions without requiring further gelation.

Another notable innovation is his patent regarding emulsion composition and vehicle, which includes a combination of water, a hydrocarbon distillate with a specific boiling point range, and a surfactant with a hydrophilic lipophilic balance number of 10 or less. This emulsion is designed to improve lithographic printing processes by reducing volatile organic compound emissions and minimizing the start-up time needed to achieve optimal print quality.
