FLUORESCENT SECURITY ENABLED INK FOR DIGITAL OFFSET PRINTING APPLICATIONS

摘要

An ink composition which is useful for digital offset printing applications contains fluorescent pigments an multiple hardening compounds. The compound has Hansen solubility parameter as stated in the specification, and the ink composition which is a result has compatibility with specific damping fluid and specific rheology properties including low viscosity. The fluorescent ink composition uses customized data for producing an anti-falsification packaging by printing security properties in high speed with the short operation.
