Abstract
A method and apparatus for color separation scanning wherein a workpiece is movably supported and scanned by a linear detector. At least one color filter is interposed in the optical path between the workpiece and the linear detector and multiple scans are taken of a linear portion of the workpiece. The data obtained from multiple scans are averaged and stored in memory. A second memory may be provided to accept data input during a scan of a subsequent portion of the workpiece while the data in the first memory is output to a print device.
