Abstract
A system for proofing which includes color scanning apparatus for scanning an input image and for producing a plurality of color separation signals corresponding to color values in the input image, proofing apparatus for producing a proof of the input image and color modification apparatus, connected between the color scanning apparatus and the proofing apparatus, for capturing the color separation signals while the color scanning apparatus scans the input image and for modifying the color separation signals to produce the proof.
Claims15
A system for proofing comprising:
- color scanning means for scanning an input image and for producing a plurality of color separation signals corresponding to color values in said input image;
- proofing means for producing a proof of said input image;
- color modification means, connected between said color scanning means and said proofing means, for capturing said color separation signals while said color scanning means scans said input image and for modifying said color separation signals to produce said proof;
- and
- exposing means for exposing a plurality of films for use in producing an output print of said input image, each film corresponding to one of said color separation signals, and wherein said proofing means and said exposing means operate at at least partially overlapping times.
A system for proofing without using a Color Electronic Prepress System (CEPS), the system comprising:
- color scanning means for scanning an input image and for producing a plurality of color separation signals corresponding to color values in said input image;
- proofing means for producing a proof of said input image;
- color modification means, connected between said color scanning means and said proofing means, for capturing said color separation signals while said color scanning means scans said input image and for modifying said color separation signals to produce said proof;
- and
- exposing means for exposing a plurality of films for use in producing an output print of said input image, each film corresponding to one of said color separation signals, and wherein said scanning means is operative to supply signals generally at the same time to said proofing means and said exposing means.
Color modification and control apparatus connectable between color scanning apparatus for scanning an image and proofing apparatus for providing a proof of the input image and exposure apparatus for exposing a plurality of films for use in producing an output print of said input image, the color modification apparatus comprising:
- scanner interface means for capturing color separation signals from said color scanning apparatus while said color scanning apparatus scans said input image;
- and
- color modification means for modifying said color separation signals to produce said proof, said interface means being operative to supply signals to both said proofing apparatus and said exposure apparatus at generally the same time.
A method for proofing comprising the steps of:
- scanning a color input image and producing a plurality of color separation signals corresponding to color values in said input image;
- while scanning said color input image, capturing said color separation signals and modifying said color separation signals to enable production of a proof of said input image;
- and
- producing said proof and, generally at the same time exposing a plurality of films for use in producing an output print of said input image, each film corresponding to one of said color separation signals.
