Embodiment Construction

[0009] 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 characters below 1mm high and lines below 0.05mm thick within the required size specifications, especially the strokes of the text. Strictly control its thickness below 0.06mm, do solid work 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", and then select the icon "Open" in the dialog box to enter the output state, and complete the RIP text and lines of the laser software. form laser file figure 2 , use special black glue with a viscosity of 14-16 seconds an...

Abstract

The invention relates to a pure line manufacturing method for gravure-printing characters with height of less than 1 millimeter and lines with thickness of 0.05 millimeter, which comprises the following steps: manufacturing solid superfine characters and lines by special typesetting software, and particularly controlling the thickness of the strokes of the characters below 0.06 millimeter; and using a copper plated roller to hang special black rubber of which the viscosity is 14 to 16 seconds and speed is 35 to 25 meters per minute, and then eroding the characters and the lines by copper chloride, wherein pre-eroding takes 15 to 20 seconds, the formal eroding time is between 80 and 150 seconds, and the eroding depth is between 15 and 16 mu. Therefore, the method achieves the aim of the superfine characters and the lines.

Description

Technical field [0001] The invention relates to a pure line production method for gravure printing characters below 1mm in height and lines below 0.05mm in thickness, which is suitable for the production process of laser engraving gravure printing plate roll technology. Background technique [0002] At present, electronic engraving technology generally cannot guarantee the clarity of text below 1mm high and the transfer printing of lines below 0.05mm thick, nor can it guarantee the uniformity of oblique lines without deformation. In addition, the depth cannot reach the depth required for printing. Because the electronic engraving machine has limitations in the number of dot lines and depth. [0003] When laser engraving technology handles ultra-fine characters and lines in gravure printing, it is generally realized by using a high line count of 300 lines / inch and deepening the hanging net. This method can only deal with small characters above 1mm in height and lines above 0....
