FOAMED PRINTING PASTES

A printed paper is produced by applying aqueous printing pastes, in a foamed form, onto the paper to be printed. As the colorant, these printing pastes contain a pigment dye or a disperse dye, but may also contain thickeners and surfactants. The present novel process permits application of aqueous printing pastes which are free from organic solvents, and consequently uniform coatings and prints which are very level (even) are obtained.

PHASE-CHANGE DIGITAL ADVANCED LITHOGRAPHIC IMAGING INKS WITH AMIDE GELLANT TRANSFER ADDITIVES

An ink composition useful for digital offset printing applications includes a colorant and a high viscosity thickening agent. The ink is formulated to incorporate a gellant into the ink set to help meet the requirement of two different viscosity or temperature pairs at two different stages of the ink delivery process. In lithography imaging a bulk ink is first transferred onto an anilox roll and then onto the imaging cylinder blanket. The first transfer from bulk ink to anilox roll requires the ink to have a low viscosity while the transfer from roll to imaging blanket requires a high viscosity. The addition of the gellant will increase the viscosity difference within the allowable temperature range thus increasing process latitude and robustness.
