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 specifically relates to a computer-simulated manual engraving method. Background technique [0002] The existing plate-making process generally adopts the manual engraving and corrosion intaglio technology. The manual engraving and corrosion intaglio is the process technology of manually engraving the original graphic on the metal plate, and then corroding the intaglio with a chemical etching solution, and then printing. The process flow is as follows: [0003] Grinding, waxing, hooking, printing, rotten copper, revising. [0004] The above-mentioned plate-making technology has the following shortcomings: First, the hand-engraved plate needs to use copperplate materials with better texture, and the graphics (mainly patterns) required by the user are carved out in layers with a carving knife based on the manual skills of the engraver. Before this, the engraver could only revise the ...

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.
