BLACK AND WHITE REPRODUCIBLE PATTERN HIGHLIGHT COLOR PRINTING (Cont'd)

The disclosed system provides a distinguishable pattern in the highlight color printed areas of a hardcopy document which will reproduce in black and white copies made of the document on a traditional xerographic copier or other black and white only document reproduction apparatus. This disclosed system may be compatibly utilized with various conventional or existing commercial copiers, printers, document scanners, image processors, page description languages and other software.

A specific feature of the specific embodiments disclosed herein is to provide a reproduction method for printing a hardcopy document with a highlight color printer so that the hardcopy document is printed with areas thereof printed with a selected highlight color imaging material and areas thereof printed with a black imaging material, which hardcopy documents may be subsequently optically copied as black and white copies on on a black and white only optical reproduction apparatus, the improvement for selected highlight color imaging materials which do not copy well on said black and white only optical reproduction apparatus, comprising printing an optically distinguishable pattern in said highlight color printed areas of said hardcopy document with said same highlight color printer concurrently with said printing of said selected highlight color imaging material in said highlight color printed areas, said optically distinguishable pattern being optically distinguishable by said black and white only document reproduction apparatus so as to automatically reproduce in said black and white copies made of said hardcopy document on said black and white only optical reproduction apparatus.

Referring to the Figures, there is shown in Fig. 1, merely by way of examples with which the present reproduction system or method 10 may be used with, or incorporated into, a document processing network 11, in which are illustrated here a physical document scanner 12, operator terminal with keyboard (user interface) 14, server 16 and highlight (or full) color printer 18 for printing the exemplary document 20 of Fig. 2, or other document. An exemplary conventional optical back and white copier on which the exemplary hardcopy document 20 of Fig. 2 may be optically copied to produce its black and white copy 30 of Fig. 3 could be or look like 18 also.
