Abstract

A system (48) and an associate method for soft proofing image (69) before print, a system (48) comprise the image (69) being displayed at a desired scale and resolution (202) such that potential artifacts can be detected before the “hard copy” is printed. One non-limiting example of an artifact which can be detected with embodiments of the present invention is Moiré effects.

Claims

1-23. -23 (Canceled)

24. A method for displaying at least a portion of an image, the method comprising:

controlling pixilation of input data corresponding to at least said portion and controlling optical magnification of a pixilated light pattern resulting from said pixilation such that said portion is displayed at a desired resolution and a desired scale.

25. The method of claim 24 comprising:

pixilating said input data according to said desired resolution; and

optically magnifying said pixilated light pattern according to said desired scale.

26. The method of claim 24, wherein said desired scale is substantially equal to the scale of said image.

27. The method of claim 24, wherein said desired resolution is substantially equal to the resolution of said image.

28. The method of claim 24 comprising at least controlling said magnification according to a ratio between said desired resolution and a resolution of said image.

29. The method of claim 24 comprising converting at least some of said input data into converted data of a lower resolution.

30. The method of claim 29, wherein said converting comprises combining a first number of pixels of said input data into a second number of combined pixels, said second number is smaller than said first number.

31. The method of claim 24, wherein said input data comprises color data, the method comprising converting at least some of said color data into converted color data corresponding to a plurality of primaries.

32. The method of claim 31, wherein said color data comprises ink data, said converting comprises:

converting said ink data into intermediate spectra; and

converting said intermediate spectra into the data corresponding to said plurality of primaries.

33. The method of claim 31, wherein said plurality of primaries comprises at least four primaries.

34. The method of claim 24, wherein said input data comprises CMYK print data.

35. The method of claim 24, wherein said image comprises an image to be printed.

36. A system for displaying at least a portion of an image, the system comprising:

a controller able to control pixilation of input data corresponding to at least said portion and able to control optical magnification of a pixilated light pattern resulting from said pixilation such that said portion is displayed at a desired resolution and a desired scale.

37. The system of claim 36 comprising:

a pixilation unit able to pixilate said input data according to said desired resolution; and

an optic magnification unit able to optically magnify said pixilated light pattern according to said desired scale.

38. The system of claim 36, wherein said desired scale is substantially equal to the scale of said image.

39. The system of claim 36, wherein said desired resolution is substantially equal to the resolution of said image.

40. The system of claim 36, wherein said controller is able to convert at least some of said input data into converted data of a lower pixel resolution.

41. The system of claim 40, wherein said controller is able to combine a first number of pixels of said input data into a second number of combined pixels, said second number is smaller than said first number.

42. The system of claim 36, wherein said magnification unit comprises at least an optical zoom lens.

43. The system of claim 36, wherein said pixilation unit comprises at least a spatial light modulator.

44. The system of claim 36 comprising a light source to apply light to said pixilation unit, said controller is able to control said light source and said pixilation unit based on at least some of said input data.

45. The system of claim 44, wherein said light source comprises at least a color wheel.

46. The system of claim 44, wherein said light source comprises at least four primary colors.

47. The system of claim 36, wherein said input data comprises color data, said controller is able to convert at least some of said color data into data corresponding to a plurality of primaries.

48. The system of claim 47, wherein said color data comprises ink data, said controller is able to convert said ink data into intermediate spectra, and said intermediate spectra into the data corresponding to said plurality of primaries.

49. The system of claim 47, wherein said plurality of primaries comprises at least four primaries.

50. The system of claim 36 comprising a screen to display a magnified pixilated light pattern resulting from said optical magnification.

51. The system of claim 36, wherein said input data comprises CMYK data.

52. The system of claim 36, wherein said image comprises an image to be printed.
