Abstract
This application relates generally systems and methods for interrupting counterfeiting workflows, and more specifically to methods for adequately concealing aspects of printer configuration, such as number of plates used to print a document or a setup of inks and split fountains. It is therefore possible to obscure the individual plate images and application of ink to those plate images, thereby impeding accurate redrawing of security artwork.
Claims29
A method comprising:
- providing ink, by a plurality of split fountains, to a plurality of printing plates each having a plate image corresponding to at least a portion of a composite image;
- wherein a given one of the plurality of split fountains corresponds to a respective one of the plurality of printing plates and contains ink at a plurality of different opacity levels based on pigment of a same color, the given one of the plurality of split fountains being configured to provide to the respective one of the plurality of printing plates an arrangement of ink unique relative to other ones of the plurality of split fountains;
- controlling oscillator rollers to set a width of an opacity level transition between the plurality of different opacity levels of the given one of the plurality of split fountains;
- transferring the ink from the plurality of split fountains to the plurality of printing plates;
- and
- pressing the plurality of printing plates to a substrate to create the composite image.

A method comprising:
- controlling a plurality of oscillator rollers to set widths of opacity level transitions of a plurality of split fountains, wherein a given one of the plurality of split fountains contains a plurality of inks of different opacity levels based on pigment of a same color;
- transferring ink from the plurality of split fountains to a plurality of printing plates, wherein a given one of the plurality of printing plates has a plate image corresponding to at least a portion of a composite image;
- and
- pressing the plurality of printing plates to a substrate to create the composite image;
- wherein the plurality of printing plates is configured to generate the composite image to have a greater number of different opacity levels than the different opacity levels contained in the plurality of split fountains.

A method comprising:
- controlling, by a plurality of oscillator rollers, widths of a plurality of opacity level transitions of a plurality of split fountains, wherein a given one of the plurality of split fountains contains a plurality of inks of different opacity levels based on pigment of a same color and configured to generate the plurality of opacity level transitions;
- transferring ink from the plurality of split fountains to a plurality of printing plates, wherein a given one of the plurality of printing plates has a plate image corresponding to at least a portion of a composite image;
- and
- pressing the plurality of printing plates to a substrate to create the composite image;
- wherein the printing plates are configured to generate the composite image to include at least one simulated opacity level transition different from any one of the different opacity levels that the plurality of split fountains are physically configured to generate.
