INK FOR EXCIMER CURING

摘要

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.
