Color-consistent three level differential gloss images
First Claim
1. A method for creating a differential gloss image comprising:
- providing first and second anisotropic halftone structures, the first and second anisotropic structures having different orientations;
applying one of the first and second anisotropic structures to image data in a first region of an image to be halftoned with a first halftone screen;
applying the other of the first and second anisotropic structures to image data in a second region of an image to be halftoned with a second halftone screen;
applying a mixture of the first and second anisotropic structures to image data in a third region of the image to be halftoned with the first and second halftone screens; and
with a printer, printing the halftoned image comprising the first second and third regions on a print media substrate, whereby on the printed substrate, the first, second, and third regions each have a gloss characteristic which differs from that of the other two regions.

Abstract
A method for creating a differential gloss image includes providing first and second anisotropic halftone structures. The first and second anisotropic structures have different orientations. One of the first and second anisotropic structures is applied to image data in a first region of an image to be halftoned. The other of the first and second anisotropic structures may be applied to image data in a second region of an image to be halftoned. A mixture of the first and second anisotropic structures is applied to image data in a third region of the image to be halftoned, whereby when printed, the three regions each have a gloss characteristic which differs from that of the other two regions.

13. A printed item comprising:
-
a substrate; and a differential gloss image printed on the substrate, the differential gloss image comprising a first region comprising a first anisotropic halftone structure, a second region comprising a second anisotropic halftone structure, different in orientation from the first anisotropic halftone structure, and a third region, abutting at least one of the first and second regions, comprising a mixture of the first anisotropic halftone structure and the second anisotropic halftone structure, whereby the third region has a gloss characteristic which differs from that of the first and second regions, wherein the different gloss characteristics provide each of the three regions with a different gloss appearance, when viewed at a particular viewing angle. - View Dependent Claims (14, 15, 16, 17)
