Abstract
A security-enhanced document with a removable SOC is provided that is compatible with process color digital imaging, method and system for producing the document enhances production, and expands the aesthetics of the documents.
Claims19
A security-enhanced Scratch-Off Coating (SOC) secured document with a plurality of SOC ink film coatings, the security-enhanced document comprising:
- a substrate, wherein lower opacity and contrast layers are sequentially printed on the substrate;
- a first process color hydrophilic primer;
- a digitally imaged process color variable indicia printed on the first process color hydrophilic primer;
- a clear, colorless, and transparent seal coat positioned over the digitally imaged process color variable indicia and at least a portion of the first process color hydrophilic primer;
- a release coat positioned over the portion of the first process color hydrophilic primer and the digitally imaged process color variable indicia;
- an upper scratch-off opacity layer positioned over at least a portion of the release coat and the digitally imaged process color variable indicia;
- a white scratch-off coating chemically modified to include a second process color hydrophilic primer, wherein the white scratch-off coating including the second process color hydrophilic primer is positioned over at least a portion of the upper scratch-off opacity layer and the digitally imaged process color variable indicia;
- and
- a digitally imaged process color overprint printed on the white scratch-off coating including the second process color hydrophilic primer.

A method of producing a security-enhanced Scratch-Off Coating (SOC) secured document with a plurality of SOC ink film coatings, the method comprising:
- sequentially printing on a substrate lower opacity and contrast layers;
- printing a first process color hydrophilic primer;
- digitally imaging process color variable indicia on the first process color hydrophilic primer;
- printing a clear, colorless, and transparent seal coat over the digitally imaged process color variable indicia and at least a portion of the first process color hydrophilic primer;
- printing a release coat over the portion of the first process color hydrophilic primer and the digitally imaged process color variable indicia;
- printing an upper scratch-off opacity layer over at least a portion of the release coat and the digitally imaged process color variable indicia;
- printing a white scratch-off coating chemically modified to include a second process color hydrophilic primer, wherein the white scratch-off coating including the second process color hydrophilic primer is printed over at least a portion of the upper scratch-off opacity layer and the digitally imaged process color variable indicia;
- and
- printing a digitally imaged process color overprint over the white scratch-off coating including the second process color hydrophilic primer.
