Abstract: A first cutter 130 (cutting unit) is provided between a color recording unit 120 (the first printing unit) and an overcoat recording unit 140 (the second printing unit). A portion whereon color printing is completed by the color recording unit 120 of a recording paper 200 (printing medium) is cut off by the first cutter 130 and detached. An overcoat recording unit 140 performs an overcoat process on the detached recording paper (printing medium strip). In parallel with this, the color recording unit 120 performs next color printing on the recording paper 200. This makes it possible to reduce a printing time in a printing device including a plurality of printing processes without deteriorating printing quality. Further, an useless paper feeding is eliminated by optimally arranging the color recording unit 120, the first cutter 130, the overcoat recording unit 140, and the second cutter 160, etc. in accordance with a size of a printing area.

Abstract: In an optical printing apparatus with employment of a low-cost arrangement, a high image quality recording operation is realized.

Abstract: In an optical printing apparatus, an image having a high image quality is desirably produced under stable condition, even when variations occur and exposure conditions are different from each other, which are caused by differences in response speeds of a light source and a liquid crystal shutter element, and also by differences in element driving conditions. The optical printing apparatus is arranged by including: image data input for inputting image data; reference level generator producing a reference level; comparator for comparing multi-value data outputted from the image data input with the reference level so as to convert the multi-value data into binary data; data transferring element for transferring the binary data outputted from the comparator as head data to the print head; latch controller for latching data of the print data; and strobe controller capable of causing the print head to expose the light therefrom.

Abstract: An optical printing apparatus capable of providing a high-quality image even on a photosensitive printing medium in which a chromophore (i.e., color-generating) density is nonlinear with respect to a quantity of exposure light. A chromophore density characteristic representative of the relation between a quantity of exposure light and a density is determined, and input image data represented by a first gradation is converted into corresponding exposure level data represented by a second gradation greater than the first gradation in accordance with the chromophore density characteristic. A print head is driven to expose the photosensitive printing medium according to the exposure level data, whereby there is obtained an image of a linear density with respect to the image data.

Abstract: Trichromatic light exposed through a liquid crystal panel upon which liquid crystal shutter elements are two-dimensionally arranged is exposed so as to form an image in the same position on a photosensitive recording medium by moving the photosensitive recording medium opposite the array of liquid crystal shutter elements. For example, the liquid crystal panel is provided with red liquid crystal shutter element rows, green liquid crystal shutter element rows, and blue liquid crystal shutter element rows, each arrayed with m liquid crystal shutter elements in a direction perpendicular to a direction of conveyance of the photosensitive recording medium, these element rows being arranged repetitively in an appropriate order at constant pitch such that (n+2) rows are arranged in the direction of conveyance of the photosensitive recording medium. Exposure through the liquid crystal shutter elements is activated every time the photosensitive recording medium is conveyed by the same distance as the constant pitch.
