    • PURPOSE:To form solid black character fill parts and to execute the high-quality character printing by forming character contour parts as grooved cells having the small width to the extent of not generating the flow of ink when ink is built up on the plate surface by rubbing the plate surface with a doctor. CONSTITUTION:The plate characters constituted formed of dots are formed when a plate coil exposed by a laser is developed and etched. The character contour parts 1 of the plate character are formed of the continuous grooved cells of 30 micron groove width and the character fill parts 2 are formed of the dot-like cells of the dot per cent of shadow parts; further, the character contour parts 1 are formed to the grooved cells having the small width to the extent of not generating the flow of the ink when the ink is built up by rubbing the plate surface with the doctor. The ink is built up in this way and if this ink is transferred and printed to paper, etc., the character contour parts are thickly inked. The ink spreads in the character fill parts and the white paper parts of screen lines disappear. The bright solid black English character A which has no serrations over the entire part of the character is thus obtd.

    • PURPOSE:To manufacture a block copy of a high precision and a good balance at high speed, by providing a character matrix plate which phototypically sets a character on a photographic printing paper in which a position is mechanically controlled with a controller via a lens, a monitor supervising a phototype setting state on the photographic printing paper, and an external controller which outputs a plotting command to the controller. CONSTITUTION:In order to manufacture a photographic printing paper 3, a plotting command from an external controller 7 is inputted to a controller 6, a position of a lens 2 on a character board 1 is controlled, and a graphic 3-1 and dimensional numerals 3-2, 3-3 are plotted on the photographic printing paper 3 via a half mirror 8. Though characters 3-4 are phototypically set from the character matrix plate 1 of a phototype setting machine, a character image on another side via the half mirror 8 is photographed with a camera 4 and projected on a monitor 5 via the controller 6. Further, the graphic 3-1 can be easily plotted by a segment with the positional control performance (plotting function) of the photographic printing paper 3 by inputting a plotting command train of a segment unit. A block copy of a character graphic mixture can be thereby obtained.
