Abstract
In a preflight process for digital print systems, color data from print data are analyzed and the results presented in a report. The color data are individually altered in regard to not only a color profile, in which they are encoded, but also in regard to their color values, using a graphic user interface. Results of the alterations are displayed using corresponding screened document pages.
Claims12
A process for processing document data containing many document pages, wherein color data are contained in the document data, the color data being encoded in a color profile and designated as input color data, comprising the steps of:
- providing logical rules or conditions for identifying positions of objects whose respective colors are to be altered, and using said logical rules or conditions, identifying said objects;
- displaying said objects by displaying respective color elements of the input color data on a display device;
- for said displayed objects executing a color conversion and generating a conversion rule therefore to change each of said displayed objects of identified position to different colors than their original colors, said different colors all being different from each other;
- altering respective color elements of the input color data in the document data for said objects according to the conversion rule, and generating output color data thereby;
- selecting a color profile in which the output color data are to be encoded from several provided color profiles;
- and
- screening at least a portion of the document data on a page-by-page basis with the output color data, and displaying the screened data on the display device.
A print system for processing document data containing many document pages, comprising:
- color data contained in the document data, the color data being encoded in a color profile and designated as input color data;
- a computer having a non-transitory computer-readable medium comprising a computer program;
- and
- said computer program performing the steps of
- providing logical rules or conditions for identifying positions of objects whose respective colors are to be altered, and using said logical rules or conditions, identifying said objects;
- displaying said objects by displaying respective color elements of the input color data on a display device;
- for said displayed objects executing a color conversion and generating a conversion rule therefore to change each of said displayed objects of identified position to different colors than their original colors, said different colors all being different from each other;
- altering respective color elements of the input color data in the document data for said objects according to the conversion rule, and generating output color data thereby;
- selecting a color profile in which the output color data are to be encoded from several provided color profiles;
- and
- screening at least a portion of the document data on a page-by-page basis with the output color data, and displaying the screened data on the display device.
A non-transitory computer-readable medium comprising a computer program for processing document data containing many document pages wherein color data are contained in the document data, the color data being encoded in a color profile and subsequently designated as input color data, said program performing the steps of:
- providing logical rules or conditions for identifying positions of objects whose respective colors are to be altered, and using said logical rules or conditions, identifying said objects;
- displaying said objects by displaying respective color elements of the input color data on a display device;
- for said displayed objects executing a color conversion and generating a conversion rule therefore to change each of said displayed objects of identified position to different colors than their original colors, said different colors all being different from each other;
- altering respective color elements of the input color data in the document data for said objects according to the conversion rule, and generating output color data thereby;
- selecting a color profile in which the output color data are to be encoded from several provided color profiles;
- and
- screening at least a portion of the document data on a page-by-page basis with the output color data, and displaying the screened data on the display device.
