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.

Energy-curable news ink containing soy oil

A lithographic ink composition that comprises a colorant having absorbency wavelength cutoffs of about 300 nm or longer, acrylate-functional materials, and a photoinitiator that absorbs at a wavelength of 300 nm or longer is formulated with a mileage of from about 1.1 to about 1.3 grams per square meter or to reach a desired print density at 2 microns or less print layer thickness. The lithographic ink cures faster and can be printed at a faster rate, particularly when curing is to be done with an excimer light source.
