Patent ID: 8328349

Claim:
A method for high speed variable printing comprising the steps of: jetting a gating agent composition onto a substrate in a pattern, the gating agent composition comprising: from about 0.05 to about 10% by weight of a blocking agent; up to about 3% by weight of a surface tension modifying compound; up to about 8% by weight of viscosity modifier such that the composition has a viscosity within the range of about 1 to 14 mPa s; and the balance of the gating agent composition comprises a solvent; wherein the gating agent has a static surface tension of less than about 40 dynes/cm; and contacting both a first area having the gating agent jetted thereon and a second area not covered by the pattern of the gating agent with a printing agent such that a print image is formed substantially only in the second area; wherein the pattern of the gating agent composition determines where the print image is formed.
