Compositions Compatible with Jet Printing and Methods Therefor

摘要

A device for use in a high speed variable printing comprises a housing having at least one surface, a series of ejection nozzles mounted on the one surface, and a source of a gating agent communicating with the nozzles. The gating agent comprises from about 0.05 to about 10% by weight of a blocking agent, up to about 15% by weight of a surface tension modifying compound, up to about 8% by weight of viscosity modifier such that the gating agent has a viscosity within the range of about 1 to 14 mPa s, and the balance of the gating agent comprises a solvent. The gating agent has a dynamic surface tension of less than about 60 dynes/cm.

1. A device for use in a high speed variable printing comprising:
a housing having at least one surface; a series of ejection nozzles mounted on the one surface, each ejection nozzle capable of ejecting a drop on demand; and a source of a gating agent communicating with the nozzles, the gating agent comprising:
from about 0.05 to about 10% by weight of a blocking agent;up to about 15% by weight of a surface tension modifying compound;up to about 8% by weight of viscosity modifier such that the gating agent has a viscosity within the range of about 1 to 14 mPa s; andthe balance of the gating agent comprises a solvent;wherein the gating agent has a dynamic surface tension of less than about 60 dynes/cm; and wherein a printing agent is applied to a further surface, wherein the gating agent is ejected in a pattern on at least one of a final print medium, the printing agent applied to the further surface, and the further surface; and wherein the printing agent is transferred from the further surface to the final print medium.
