Abstract
Apparatus and methods for controlling application of a substance to a substrate involve the use of a functional agent that blocks the substance from or attracts the principal substance to the substrate. The apparatus and methods may utilize ink jet technology to apply the functional agent directly to the substrate or to an intermediate surface. The principal substance may be an ink, a dye, a marking substance other than an ink, or a carrier for any other type of substance.
Claims25
An apparatus for printing, comprising:
- a substrate having a surface;
- means for jetting a first gating agent;
- a layer of first gating agent having a first pattern associated with the substrate;
- means for applying a principal substance;
- a layer of principal substance having a second pattern associated with the substrate;
- and
- means for transferring the principal substance from the substrate to a print medium in the second pattern,
- wherein the first pattern and the second pattern are the same when the layer of first gating agent is intermediate the substrate surface and the layer of principal substance, and the first pattern and the second pattern are different when the layer of principal substance is intermediate the substrate surface and the layer of first gating agent, and
- wherein the layer of the first gating agent and the layer of the principal substance are capable of being varied per revolution.

A method of printing, comprising the steps of:
- jetting in a first pattern a first gating agent onto a substrate having a surface;
- applying a principal substance to the substrate;
- and
- transferring the principal substance from the substrate to a print medium in a second pattern;
- wherein if the first pattern is the same as the second pattern, the jetted layer of the first gating agent is intermediate the substrate surface and the principal substance and in this case the gating agent assists the transfer of the principal substance to the print medium, and if the first pattern is different from the second pattern, the principal substance is intermediate the substrate surface and the jetted layer of the first gating agent and in this case the principal substance is transferred to the print medium where there is no gating agent.
