Abstract

The present invention relates to the segmentation of an image into a main area and a image segment for variable glossmark data. By selectively applying halftones with anisotropic structure characteristics which are significantly different in orientation while remaining identical in density to the image segment, a variable glossmark may be superimposed within an image with reduced processing and storage requirements.

Claims

1. A method for variable glossmark control comprising:

segmenting an image of interest into a main area and a segment area

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 the main area and at least some portion of the segment area; and

applying the second halftone to the remaining portion of the segment area to produce a variable glossmark.

2. The method of claim 1 wherein the first anisotropic structure orientation and the second anisotropic structure orientation are 90 degrees apart.

3. The method of claim 2 wherein the first anisotropic structure has a horizontal orientation and the second anisotropic structure has vertical orientation.

4. The method of claim 3 wherein the first and second halftones are line type halftones.

5. The method of claim 3 wherein the first and second halftones are dot type halftones.

6. The method of claim 2 wherein the first anisotropic structure has a 45 degree orientation to the right and the second anisotropic structure has a 45 degree orientation to the left.

7. The method of claim 1 wherein the first anisotropic structure orientation and the second anisotropic structure orientation are less than 90 degrees apart.

8. The method of claim 1 wherein the variable glossmark is intended for an ink jet printer.

9. The method of claim 1 wherein the variable glossmark is intended for an electrostaticgraphic printer.

10. The method of claim 1 wherein the variable glossmark is intended for printing upon paper.

11. The method of claim 1 wherein the variable glossmark is intended for printing upon a transparency.

12. The method of claim 1 wherein the variable glossmark indicates time information.

13. The method of claim 1 wherein the variable glossmark indicates date information.

14. The method of claim 1 wherein the variable glossmark indicates identification information.

15. The method of claim 14 wherein the variable glossmark indicates serial number information.

16. The method of claim 1 wherein the variable glossmark indicates monetary value information.

17. The method of claim 1 wherein the variable glossmark indicates job processing information.

18. The method of claim 1 wherein the variable glossmark indicates a bar-code.

19. The method of claim 1 wherein the variable glossmark indicates a logo.

20. A method for variable glossmark control comprising:

segmenting an image of interest into a main area and a segment area;

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;

selecting a third halftone different from the first halftone and the second halftone;

applying the first halftone to at least some portion of the segment area;

applying the second halftone to the remaining portion of the segment area to produce a variable glossmark; and

applying the third halftone to the main area.

21. The method of claim 20 wherein the third halftone is a stochastic type.

22. The method of claim 20 wherein the third halftone is a cluster dot type.

23. The method of claim 20 wherein the variable glossmark is intended for an ink jet printer.

24. The method of claim 20 wherein the variable glossmark is intended for an electrostaticgraphic printer.

25. The method of claim 20 wherein the first anisotropic structure orientation and the second anisotropic structure orientation are 90 degrees apart.

26. The method of claim 20 wherein the first anisotropic structure orientation and the second anisotropic structure orientation are less than 90 degrees apart.

27. The method of claim 20 wherein the third halftone has an anisotropic structure orientation different from both the first halftone and the second halftone.

28. The method of claim 25 wherein the first anisotropic structure has a 45 degree orientation to the right and the second anisotropic structure has a 45 degree orientation to the left.

29. The method of claim 20 wherein the variable glossmark indicates time information.

30. The method of claim 20 wherein the variable glossmark indicates date information.

31. The method of claim 20 wherein the variable glossmark indicates identification information.

32. The method of claim 20 wherein the variable glossmark indicates serial number information.

33. The method of claim 20 wherein the variable glossmark indicates monetary value information.

34. The method of claim 20 wherein the variable glossmark indicates job processing information.

35. The method of claim 20 wherein the variable glossmark indicates a bar-code.

36. The method of claim 20 wherein the variable glossmark indicates a logo.
