Problems solved by technology

The processing of laser plate is complicated, the cycle is long, and the cost is twice as much as that of electric engraving plate
In order to make a laser plate, some customers wait a week or even more than ten days for the delivery cycle, which seriously shortens the customer's printing time

Embodiment 1

[0014] An electric engraving and binding process. This process uses a combined engraving method for two engravings. First, a 0.25mm wide line is carved around the selected pattern, and then the line and the selected pattern are expanded and contracted by 0.1mm. Leave a 0.15mm engraving amount, first use the rough carving process to carve the selected pattern, and then use the fine carving process to sculpt the surrounding lines, so that the two dots are exactly connected, and the fine lines carved afterwards are just the jagged edges of the rough carving. Pressed together. I can't see any aliasing. Such as figure 1 Shown.

Embodiment 2

[0016] An electric engraving and edge binding process. This process uses a combined engraving method for two engravings, first engraving a 0.2mm wide line around the selected pattern, and then expanding and contracting the line and the selected pattern by 0.05mm. Leave a 0.1mm engraving amount, first use the rough carving process to carve the selected pattern, and then use the fine carving process to sculpt the surrounding lines, so that the two dots are just connected, and the fine line after the carving is just the jagged edge of the rough carving. Pressed together.

Embodiment 3

[0018] An electric engraving and binding process. This process uses a combined engraving method for two engravings, first engraving a 0.3mm wide line around the selected pattern, and then expanding and contracting the line and the selected pattern by 0.15mm. Leave a 0.2mm engraving amount, first use the rough carving process to carve the selected pattern, and then use the fine carving process to sculpt the surrounding lines so that the two dots are exactly connected, and the fine lines carved afterwards just match the jagged edges of the rough carving. Pressed together.

Abstract

The invention relates to a glyphographic binding technology. According to the technology, twice carving is carried out by a carving method in a combination way. The technology comprises the following steps of: firstly, carving a line with the width of 0.2mm-0.3mm along the periphery of a selected pattern, expanding and shrinking the line and the selected pattern by 0.05mm-0.15mm with externally remaining 0.1mm-0.2mm of a carving clearance, carving the selected pattern by a coarse carving technology, and carving the peripheral line in a combination way by a fine carving technology, so that two network points can be just connected with each other, and the rear-carved thin line can be just pressed with a coarsely-carved picot edge together. Compared with the prior art, the glyphographic binding technology provided by the invention has the advantages of good carving effect and the like.

Description

Technical field [0001] The invention relates to an electric carving process, in particular to an electric carving edge binding process. Background technique [0002] The pattern of the electro-engraving plate is composed of dots, and the dots are formed by the mechanical movement of the electro-engraving needle. The edge of the pattern cannot form continuous dots due to the arrangement of the dots, and it will form a rough feeling. The edge of the pattern cannot be guaranteed to be as smooth as flexographic printing, and jaggedness will occur. Sawtooth can't be completely eliminated, only try to adjust it to make it inconspicuous. [0003] At present, it is generally improved by adjusting the network line and the screen angle, but after adjusting the network line and the screen angle, although the serrations are very small and the edge of the pattern is much softer, the engraving depth is difficult to meet the requirements, and the printed color will be much lighter. Can not meet...
