Abstract
The present invention relates to creating differential gloss images in clear toner by the manipulation of halftones employed prior to the depositing of the clear toner layer upon a substrate. By selectively applying halftones with anisotropic structure characteristics which are significantly different in orientation although remaining identical in density, a differential gloss image may be superimposed within even clear toner as applied to paper. Further, this technique may be used to enhance color toner Glossmark images across the low and high density areas of application where the differential gloss effect would otherwise be weak.
Claims21
A method for the manipulation of the differential gloss in a hardcopy output comprising the steps of:
- selecting a first halftone having a first anisotropic structure orientation;
- selecting a second halftone having a second anisotropic structure orientation different from that of the first halftone;
- applying the first halftone to at least some portion of a halftone image;
- applying the second halftone to the remaining portion of the halftone image;
- and,
- applying a clear toner to the hardcopy output of the halftone image resulting from the above steps where a first portion of the applied clear toner is provided with a third halftone having a third anisotropic structure orientation and a remaining portion of the applied clear toner is provided with a forth halftone having a forth anisotropic structure orientation.
A method for the manipulation of the perceived differential gloss upon a substrate comprising the steps of:
- selecting a first halftone having a first anisotropic structure orientation;
- selecting a second halftone having a second anisotropic structure orientation different from that of the first halftone;
- applying the first halftone to a first portion of a clear toner layer deposited upon a substrate;
- and,
- applying the second halftone to the remaining portion of the clear toner layer deposited upon a substrate.
A method for the manipulation of the differential gloss in a hardcopy output comprising the steps of:
- selecting a first halftone having a first anisotropic structure orientation;
- selecting a second halftone having a second anisotropic structure orientation different from that of the first halftone;
- applying the first halftone to a first portion of a first clear toner layer deposited upon a substrate;
- applying the second halftone to the remaining portion of the first clear toner layer deposited upon a substrate;
- selecting a third halftone having a third anisotropic structure orientation;
- selecting a forth halftone having a forth anisotropic structure orientation different from that of the third halftone;
- applying the third halftone to at least some first portion of a halftone image;
- applying the forth halftone to the remaining portion of the halftone image;
- applying a color toner layer representative of the halftone image comprising the third and forth halftone as deposited upon the first clear toner layer;
- and,
- applying a second clear toner layer to the hardcopy output of the halftone image resulting from the above steps where a first portion of the applied second clear toner layer is provided with a fifth halftone having a fifth anisotropic structure orientation and a remaining portion of the applied second clear toner layer is provided with a sixth halftone having a sixth anisotropic structure orientation.
