    • An electronic printing method by which originals are photographically reproduced by exposing high-contrast copy material with an intensity modulated illumination source that coarsely scans the original while the original is sharply imaged with a well-cor­rected optical system. The source intensity is modulated to compensate for the original's tonal qualities and electronically shapes the response of the copy material to enhance tonal reproduction. The imaging system in conjunction with the high-contrast material assures high reproduction of detail. The method enhances copy sharp­ness and reduces copy time, memory and computational needs otherwise required for copies of comparable quality.
    • 一种电子打印方法,通过在用正确校正的光学系统锐利地成像原稿的情况下,通过使用粗调扫描原稿的强度调制照明源曝光高对比度复印材料来照相原稿。 源强度被调制以补偿原始的色调质量,并且电子地形成复印材料的响应以增强色调再现。 与高对比度材料结合的成像系统确保细节的高再现性。 该方法提高了拷贝的清晰度,并缩短了可比质量副本所需的复制时间,内存和计算需求。

    • An image printer includes a projection-exposure section for projecting an image born on a film onto a photosensitive material, an image-exposure section for exposing the photosensitive material based on image information comprised of a plurality of image areas each including color data relating to a plurality of colors, and a transport unit for transporting the photosensitive material through the projection-exposure section and the image-exposure section. The image-exposure section includes a plurality of exposure units for dividing the image information into a plurality of lines and exposing the photosensitive material with switching exposing colors corresponding to the plurality of color data, a moving device for moving the plurality of exposure units and the photosensitive material relative to each other in a direction perpendicular to the lines, and a moving-exposure control unit for controlling operations of the exposure units and the moving device. The exposure control unit is capable of effecting a moving exposure control in which the plurality of exposure units respectively effect exposure operations thereof in a parallel manner.
