Abstract

A display for soft proofing an image to be reproduced using a set of selected printing colors includes a plurality of display elements each for displaying a color substantially spectrally matched to one of a set of printing colors.

Claims

1. A display for soft proofing an image to be reproduced using a set of selected colorants, comprising:

a plurality of display elements each for displaying a color substantially spectrally matched to one of the set of colorants; and

means for illuminating the display elements.

2. The display of claim 1, wherein the display elements comprise overlapping color filter layers.

3. The display of claim 2, further including securing means including adhesive for maintaining the display elements in overlapping relation.

4. The display of claim 1, wherein the selected colorants comprise printing process colors.

5. The display of claim 1, wherein at least one of the selected colorants comprises a printing non-process color.

6. The display of claim 1, wherein the illuminating means comprises illumination source for backlighting the display elements.

7. The display of claim 6, wherein the illumination source has a substantially flat spectral characteristic curve.

8. The display of claim 6, wherein an intensity level of the illumination source is selected to limit a gamut of displayed colors.

9. The display of claim 1, wherein the illuminating means comprises a cathode ray tube.

10. The display of claim 1, further including means for modulating light produced by the illuminating means.

11. The display of claim 10, wherein the modulating means comprises a plurality of liquid crystal display elements.

12. The display of claim 10, wherein the modulating means comprises a film layer.

13. The display of claim 10, wherein the modulating means comprises a particle layer.

14. A liquid crystal display for soft proofing an image to be reproduced using a set of selected printing colors, comprising:

a plurality of overlapping display elements each for displaying a color substantially spectrally matched to one of the set of printing colors;

means for securing the display elements together to form the display; and

means for backlighting the liquid crystal display layers.

15. The display of claim 14, wherein an intensity level of the backlighting means is selected to limit a gamut of displayed colors.

16. The display of claim 15, wherein the backlighting means has a substantially flat spectral characteristic curve.

17. The display of claim 16, wherein the set of selected colors are process colors including cyan, magenta and yellow.

18. The display of claim 16, wherein the set of selected colors includes at least one non-process color.

19. A method of fabricating a display for soft proofing an image to be printed with selected colors, the method comprising the steps of:

choosing color display elements that are substantially spectrally matched to the selected colors; and

providing means for illuminating the color display elements.

20. The method of claim 19, wherein the illuminating means comprises a black and white cathode ray tube.

21. The method of claim 19, including the further step of modulating light from the illuminating means.

22. The method of claim 21, wherein the modulating step includes the step of operating a set of liquid crystal display elements.

23. The method of claim 21, wherein the modulating step includes the step of providing a film layer.

24. The method of claim 21, wherein the modulating step includes the step of providing a particle layer.

25. The method of claim 19, wherein the illuminating means comprises a source for backlighting the display elements.

26. The method of claim 19, wherein the illuminating means has a substantially flat spectral characteristic curve.

27. The method of claim 19, wherein an intensity level of the illuminating means is selected to limit a gamut of displayed colors.

28. The method of claim 19, wherein the selected colors comprise process colors.

29. The method of claim 19, wherein at least one of the selected colors comprises a non-process color and remaining selected colors are process colors.

30. A method of soft proofing an image to be reproduced using a set of selected colors on paper, the method comprising the steps of:

providing a display having color display elements substantially spectrally matched to the set of selected colors; and

operating the display to reproduce the image.

31. The method of claim 30, wherein the set of selected colors includes three process colors.

32. The method of claim 30, wherein at least one of the set of selected colors comprises a non-process color.

33. The method of claim 30, wherein the step of operating includes the step of backlighting the display with an illumination source.

34. The method of claim 33, wherein the illumination source has a substantially flat spectral characteristic curve.

35. The method of claim 34, wherein an intensity level of the illumination source is selected to limit a gamut of displayed colors.
