Abstract: An energy curable ink composition comprising an acrylate-functional derivative of soybean oil and one or more further acrylate-functional materials is suitable for printing on a cold-set lithographic press and is cured by exposure to an actinic radiation source located on the press.

Abstract: A method for preparing an organic pigment dispersion, such as a flush pigment or ink product, comprises steps of introducing into a twin screw extruder a stable, water-borne pigment dispersion, an organic medium, and a destabilizing agent; mixing together the stable, water-borne pigment dispersion, the organic medium, and the destabilizing agent to produce a pigment flush phase and a water phase; and removing at least a part of the water phase. A twin-screw extruder for carrying out the flushing method has an addition and flushing zone, a water removal zone, and a zone for rinsing the crude organic pigment dispersion or flush with water and removing the rinse water. Additional materials may be added to form a finished pigmented product such as an ink product, masterbatch, or toner.

Abstract: A system is provided that includes a first computer that can communicate with a second computer. The second computer sends information to the first computer that includes a desired ink color and optionally includes information of other desired ink properties. The first computer includes a database of data for predicting color data of ink formulations using a selected ink base color set, a software program for selecting an ink formulation based on data for a desired ink, and a software program for sending information to the second computer to display the color of the selected ink formulation on a color monitor connected to the second computer. The ink base color set can be selected to provide other desired properties for the ink, such as low cost, light fastness, or chemical resistance.
