Embodiment Construction

[0010] In the process diagram of the embodiment, use special typesetting software to create a new file, set the page size, set the size specifications, and then make text and lines within the required size specifications, then copy a layer of text and lines, and indent them by 0.01 mm-0.015mm unilateral line, placed directly above the original large text and lines, filled with a certain amount of hanging net, combining the original large solid text and lines with the retracted hanging net text and lines, and completing the package solid side line 0.01mm-0.015mm text and lines figure 1 , use this special typesetting software to export the PS format file, and then transmit the PS file to the laser computer through the LAN, open the laser software, select the "Open" menu, select the PS file in the pop-up dialog box, and then select "Modify" in the dialog box icon, enter the parameters of resolution, mesh shape, number of lines, and angle in the dialog box that pops up, press "OK"...

Abstract

The invention relates to an edge covering method for sawteeth at edges of photogravure characters and lines, which comprises the following steps: adding solid edge covering lines of 0.01 millimeter to 0.015 millimeter to the edges of the characters and the lines by special typesetting software, manufacturing a hanging mesh in the middle, then ablating out the characters and the lines on a copper plated roller evenly coated with black rubber by a normal laser engraving machine after resolution factor, mesh configuration, line number and angle parameters RIP are added by laser software, and finally etching the ablated characters and the lines by copper chloride to prepare the characters and the lines without serrated edges.

Description

Technical field [0001] The invention relates to an edge-wrapping method for solving gravure printed characters and line edge jaggedness, which is suitable for the production technology of laser engraving gravure printing plate rolls. Background technique [0002] At present, electronic engraving technology is widely used in gravure printing plate making enterprises. Since the engraving mesh is a complete diamond dot and the engraving height is 140 lines / cm, electronic engraving technology cannot solve the jagged edges of gravure printing text and lines. [0003] In the normal process of advanced laser engraving, since a certain gap (mesh wall) must be reserved between the engraved dots, although the number of engraving lines can be increased, in order to ensure the normal transfer of gravure printing, it is necessary to ensure that the dots There is a gap (mesh wall) above 3μ, so the normal process of laser engraving cannot solve the jagged edges of gravure printed text and ...
