1. a mirror plane erosion carving gravure technique is characterized in that technological process is:

  • carry out surface finish after selecting plate;

    In plate surface silk-screen photosensitive-ink;

    By developing again and baking after the printing down;

    Corrode after the maintenance, produce dimpled grain;

    Carry out again degumming process and slough the space of a whole page all medicine film and coating agents which has to be dissolved in alcohol before use;

    Then carry out intaglio plate chromium plating;

    At last plate is overhauled and cuts;

    According to the layer of structure of figure line, the gradation surprint;

    According to the thickness of figure streakline bar, carry out the bottom screening and process;

    Described printing down namely is according to the requirement of printing type, determines that the space of a whole page is well-behaved, the seaming position, and the medicine face of film fits with the China ink layer of version, and printing down is bled, and utilizes UV-lamp to carry out printing down;

    Described gradation surprint is exactly in when design, divide n look slice according to the level of figure line, and respectively n time in the silk-screen photosensitive-ink and corrode and carry out the gradation surprint between flow process and corrode;

    The gradation surprint should be followed first thick rear thin principle, and the system of solarization needs to determine the printing down time according to the lines degree of depth of wanting screening and the situation of mesh.
