Method for simulating plate making by computer instead of band engraving

Abstract

A method fo r preparing woodcut by computer to simulate manual carving features that a group of vector lines with different widthes is used to map the gray scales of traditional woodcut. Its advantage is high productivity.

Description

technical field [0001] The invention belongs to the technical field of plate making technology, and in particular relates to a method for computer simulation of manual engraving and plate making. Background technique [0002] The existing plate-making process generally adopts manual engraving and etching gravure technology. Manual engraving and etching intaglio is a process of manually engraving the original graphic on the metal plate, and then corroding it with a chemical etching solution to make an intaglio, and then printing. Its process flow is as follows: [0003] Grinding, waxing, hook drawing, printing, rotten copper, and revision. [0004] In the above-mentioned plate-making process technology, there are the following disadvantages: First, the hand-engraved plate needs to use a copper plate material with a better texture, and the graphics and texts (mainly patterns) required by the user are carved out in layers with a carving knife by the engraver's manual skills. ...

Problems solved by technology

[0004] In the above-mentioned plate-making technology, there are the following disadvantages: First, the hand-engraved plate needs to use a copper plate material with a better texture, and the graphics and texts (mainly patterns) required by the user are carved out in layers with a carving knife by the hand-crafted skills of the engraver. Before that, the engraver could only use the blueprint in his mind, or the existing sketch manuscript, to carry out revision with a knife, which required high engraving technology for engraving, which undoubtedly lengthened the working cycle to a certain extent and reduced the work efficiency

If there is a little mistake, all previous efforts may be wasted

Secondly, the chemical etching method can only produce one level, and the dead angle of the edge cannot be made into a certain curvature like hand-carving to improve the embossing effect and prevent the paper from cracking.
