ADDITIVES TO LITHO INKS TO ELIMINATE INK FEEDBACK

摘要

Provided are web offset lithographic ink compositions that contain an alkyl thioether surfactant an alkoxylated modified rosin or a combination thereof. The ink compositions can be oil based inks or water based inks that can be radiation curable. The resulting ink compositions can be used in web offset lithographic printing to substantially reduce or eliminate the ink feedback and ink build up that occurs during printing. Also provided are methods for reducing or eliminating ink feedback and build up during lithographic printing processes.
