Abstract

In a method or system for automatic preparation of print data for a printing process, the print data is imported and subdivided into segments. The segments are analyzed with an image analysis method for automatically determining presentation parameters for the respective segments such that an image content of the respective segments is analyzed for at least one of color depth, contrast, sharpness, brightness, color space, detail richness, or resolution. The print data together with the automatically determined presentation parameters are provided to control the printing process.

Claims

1-26. -26. (canceled)

27. A method for automatic preparation of print data for a printing process, comprising the steps of:

importing the print data;

sub-dividing the print data into segments;

analyzing the segments with an image analysis method for automatically determining presentation parameters for the respective segments such that an image content of the respective segments is analyzed for at least one of color depth, contrast, sharpness, brightness, color space, detail richness, or resolution; and

providing the print data together with the automatically determined presentation parameters to control the printing process.

28. A method according to claim 27 wherein a specific image analysis method is selected depending on a respective data type of the segment.

29. A method according to claim 27 wherein a Fourier analysis or frequency analysis is used as an image analysis method to determine the resolution of the print data of the respective segment.

30. A method according to claim 27 wherein an expert system is used as an image analysis method, to which expert system are provided as input values the print data of the segment, and parameters determined by means of pre-analysis methods, with which respective print data the presentation parameters are associated.

31. A method according to claim 27 wherein a neural network is used as an image analysis method, to which neural network are provided as input values the print data of the segment and parameters determined by means of pre-analysis methods, with which respective print data the presentation parameters are associated.

32. A method according to claim 27 wherein a fractal image analysis method is used as an image analysis method with which self-similar segments can be extracted.

33. A method according to claim 27 wherein information contained in a job ticket are used to determine the presentation parameters or render them more precisely.

34. A method according to claim 27 wherein before the analysis of the print data, the print data are broken down into specific color separations, wherein image analysis methods are individually applied to the color separations.

35. A method according to claim 34 wherein the color separations are represented by means of polynomial curves and a respective set of support points.

36. A method according to claim 27 wherein the print data, together with the automatically determined presentation parameters, are stored on an apparatus automatically associated with a printer.

37. A method according to claim 36 wherein different print data are combined with their respective presentation parameters into a print job and are printed out at the printer.

38. A method according to claim 36 wherein the presentation parameters are provided in output parameters to control the printing process.

39. A method according to claim 27 wherein the automatically determined presentation parameters are used to directly control the printing process.

40. A method according to claim 27 wherein the sub-division of the print data into segments occurs automatically by means of the image analysis method.

41. A method to automatically prepare print data of a printing process, comprising the steps of:

importing the print data;

breaking down the print data into predetermined color separations;

analyzing the color separations with an image analysis method to automatically determine contiguous areas of similar color; and

compressing the print data wherein the contiguous areas are parameterized.

42. A method according to claim 41 wherein the contiguous areas are determined by means of Fourier analysis or a random walk method.

43. A method according to claim 41 wherein boundary lines of the contiguous areas are parameterized.

44. A method according to claim 43 wherein color curves within the contiguous areas are parameterized.

45. A method according to claim 44 wherein color curve smoothing functions running approximately transversal to the boundary lines are used on the boundary lines.

46. A method according to claim 41 wherein processing instructions that specify how the parameterized areas have been determined are stored together with the compressed print data.

47. A method according to claim 41 wherein processing instructions that describe a possible pre-processing of the print data are stored together with the parameterized areas.

48. A method according to claim 41 wherein the parameters generated in the compression are directly used as inputs for an image analysis.

49. A system for automatic preparation of print data for a printing process, comprising:

a computer on which a computer readable medium is provided having a program for performing the steps of;

importing the print data;

subdividing the print data into segments;

analyzing the segments with an image analysis method for automatically determining presentation parameters for the respective segments such that an image content of the respective segments is analyzed for at least one of color depth, contrast, sharpness, brightness, color space, detail richness, or resolution; and

providing the print data together with the automatically determined presentation parameters to control the printing process.

50. A system according to claim 49 wherein the computer is arranged in a network to transmit print data to one or more printers.

51. A system according to claim 50 wherein the computer comprises a print preparation computer or a print server.

52. A system according to claim 49 wherein the computer comprises a controller of a printer.
