Abstract

A system that enables quickly, reliably and automatically producing quality copies of a physical color image, utilizing an available digital printer or digital press. The system consists of a scanner and a digital processor, commonly housed and interfaced to the printer, and an integrated software package. It features a novel image processing flow, whereby scanning, processing and outputting to the printer proceed as a continuous sequence of operations on the image data, without any intermediate files being created and without any intervention by the operator of the system. Scanning, processing and printing of different images may take place simultaneously in a pipeline fashion.

Claims

cause the printer to print said page image;

and wherein said processing of image data is carried out automatically according to a set procedure, which includes at least a first and second subprocedure, in sequence, each associated with parameters, none of said parameters being alterable during said processing,

said first subprocedure including processing associated with any single original image and

said second subprocedure including processing associated with any single page image;

and wherein

said first subprocedure is divided into a plurality of paths, each corresponding to one of said types, and

said processing of data from the original image or from any portion thereof is carried out along the one of said paths that corresponds to its type.

2. The attachment of claim 1, wherein any of said parameters are set automatically prior to said processing.

3. The attachment of claim 1, wherein the original image or portions thereof are automatically classified into respective types prior to said processing.

4. The attachment of claim 1, wherein at least one of said types is solid graphics and image processing according to the corresponding one of said paths includes processing of binary valued data.

5. The attachment of claim 1, wherein said second subprocedure is operative to cause the page image to include a version of each of a plurality of original images or a plurality of copies of an original image.

6. The attachment of claim 1, further comprising an image display means and operator input means and wherein said computer is further programmed to be operative to display an image on said image display means, and to be responsive to said operator input means, so as to enable the operator to set one or more of said parameters interactively with said displayed image prior to said processing.

7. The attachment of claim 6, wherein said displayed image is a preview version of the original image.

8. The attachment of claim 6, wherein said displayed image is a geometric representation of the page image to be printed.

9. The attachment of claim 1, wherein said digital printer is a digital press.

10. The attachment of claim 1, wherein said digital printer is a press with a provision for on-press recording of images onto printing forms.

11. The attachment of claim 1, further comprising a housing, wherein said scanner and said computer are housed in common in said housing.

12. The attachment of claim 1, wherein said computer is a general-purpose computer and said programming is effected entirely by a specially designed integrated software package.

13. The attachment of claim 1, wherein said scanning of any one image may occur simultaneously with said processing of data of at least one other image.

14. A system for reproducing physical original images as printed copies, any original image or portions thereof being classifiable into a finite number of types, comprising--

a digital computer, including storage,

a scanner, connected to said computer, and

a digital printer, connected to said computer and housed separately from said scanner and said computer and operative to receive digital page images, in print raster format and to print multiple copies of any such page image in a plurality of printing colors;

wherein said computer is programmed to automatically, after receiving a copy command from an operator,

cause said scanner to scan an original image,

process resultant image data so as to obtain a complete digital representation of the page image,

cause said representation to be transferred to said printer as a page image in said print raster format, separated by printing colors, and

cause said printer to print the page image;

and wherein said processing of image data is carried out in its entirety according to a set procedure, which includes at least a first and a second subprocedure, in sequence, each associated with parameters, none of said parameters being alterable during said processing,

said first subprocedure being associated with any single original image and

said second subprocedure being associated with any single page image;

and wherein

said first subprocedure is divided into a plurality of paths, each corresponding to one of said types, and

said processing of data from the original image or from any portion thereof is carried out along the one of said paths that corresponds to its type.

15. The system of claim 14, wherein any of said parameters are set automatically prior to said processing.

16. The system of claim 14, wherein the image or portions thereof are automatically classified into respective types prior to said processing.

17. The system of claim 14, wherein at least one of said types is solid graphics and image processing according to the corresponding one of said paths includes processing of binary valued data.

18. The attachment of claim 14, wherein said second subprocedure is operative to cause the page image to include a version of each of a plurality of original images or a plurality of copies of an original image.

19. The system of claim 14, further comprising an image display means and operator input means and wherein said computer is further programmed to be operative to display an image on said image display means, and to be responsive to said operator input means, so as to enable the operator to set one or more of said parameters interactively with said displayed image prior to said processing.

20. The system of claim 19, wherein said displayed image is a preview version of the original image.

21. The system of claim 19, wherein said displayed image is a geometric representation of the page image.

22. The system of claim 14, wherein said printer is commercially supplied, and operable, independently from said scanner and said computer.

23. The system of claim 14, wherein said computer is connected to said printer by means of a standard interface or network.

24. The system of claim 14, wherein said digital printer is a digital press.
