The number of engraved lines is inversely proportional to the degree and depth of the mesh. The number of engraving lines is small, the width of a single mesh is large and the depth is deep. On the contrary, the width and depth of a single mesh are small; ? In the highlight area, there is little difference between the reflective density with more lines and the less lines. In the dark area, the holes with fewer lines are larger and deeper than those with more lines. The large amount of ink stored in the mesh and the thick ink layer of the substrate are the main factors affecting the reflection density, so the reflection density is higher when the number of engraved lines in the dark area is low; The first step in drawing is to draw the sculpture you need. There are many softwares such as autoCAD, UG, Pro/E and so on. You can also draw with the software that generates the tool path, but it takes a long time to draw, and the software that generates the tool path is not a professional drawing. The second step is to generate the tool path and set the spindle parameters. The third step is the engraving machine control software such as Mach3-D macro card system. File format: cdr, ai, eps, pdf and other vector diagrams. Size: There are three commonly used cards, 85mm×54mm, 80mm×50mm and 76 mm× 44 mm.. Other shapes and sizes of cards can also be made according to customer requirements.

Lace: You can choose from the company's lace library or design it at will. Shading: You can only choose from the company's shading library (or press the sample card) or the customer can design and make the mold himself. Code: printable code (also known as plane code), etched convex code, etched concave code and embossed code. Category: personal/group business cards, creative gift cards, VIP cards, smart magnetic stripe cards, and special-purpose items. Customize your own distinguished card, size: You can choose our standard card or specify your own size. Thickness: The thickness of the card can be customized according to individual needs. Magnetic stripe: It is absolutely necessary for individuals to configure a writable magnetic stripe. Pattern: according to the existing materials to do different patterns of grain effect. Shape: You can make different shapes according to your needs. Number: digital printing can be arranged in sequence. This function is used for VIP cards. Material: jewelry-grade sterling silver, fine steel, copper, alloy (special metal material for jewelry) technology, carving and coloring, hollowing out modeling, stamping concave and convex, frosted signature, etching and printing, electroplating, surface cleaning, frosting, antique, coloring and electroplating. Standard electroplating color: free use of standard color; Customers' own colors are charged separately. There will be slight color difference between electroplated plates.
