Abstract
Image data conversion processor converting a raster format of composed image data comprising line-work and picture data into a format of engraving pixel data for realizing a staggered-row screen of gravure printing cells, image density weighted for high-fidelity reproduction of tone value and line sharpness of an originally scanned image pattern. The dual-valued line-work pixels are in high concentration relative to the picture data pixels and are converted into multiple-valued line-work equivalent pixels in a picture-raster equivalent format. The multiple-valued line-work data and the picture data are assembled according to layout data operator controlled through a CRT to form the composed image data for conversion. A format converter in the processor maps the converted multiple-valued line-work equivalent pixels in the picture-raster equivalent format into gravure engraving pixels each corresponding to an engraved gravure cell of the stagger-format printing screen.
