Method of high-speed variable printing

摘要

A method for high speed variable printing comprises the steps of jetting a gating agent composition onto a substrate in a pattern and applying a printing agent to the substrate to form a print image in areas not covered by the pattern of the gating agent. The gating agent composition comprises from 0.05 to 10% by weight of a blocking agent; up to 3% by weight of a surface tension modifying compound; up to 8% by weight of a viscosity modifier; and the balance a solvent. The gating agent composition has a viscosity within the range 1 to 14 mPa s and a dynamic surface tension of less than 60 dynes/cm.
