A board surface with three-dimensional visual effect and its manufacturing method

Abstract

The present invention is a board surface with stereoscopic visual effects and a manufacturing method, wherein, the board surface is provided with a number of shallow carving points, and the shallow carving points are arranged in sequence to form a number of lines, and the lines are provided with interrupted point, a plurality of the break points are set continuously, and the break points on the multiple lines are set adjacently; the line is formed by arranging shallow carving points, the break point is set on the line, and the break point on the multiple lines is The dots are arranged adjacent to each other to form a blank area. Due to the difference in reflectivity between the shallow carving points and the board surface, the three-dimensional sense of the line set is highlighted through the blank area. This production method does not divide the line set, and adjusts the line shape and sparseness of the lines. The density optimizes the stereo vision, which can quickly carry out machine reproduction.

[0002] Commemorative coins are legal tenders issued to commemorate international or national political, historical, cultural and other major events, outstanding figures, places of interest, rare animals and plants, sports events, etc. It includes ordinary commemorative coins and precious metal commemorative coins, commemorative As a special commodity that serves as a general equivalent, coins also have high collection, value preservation and investment value. In order to highlight the content expressed by commemorative coins, such as characters, places of interest, sports events, etc., it is necessary to make a three-dimensional effect. Embossing, sandblasting, high relief and other processes are used to make the height of the pattern higher than the coin surface, increasing its three-dimensional sense and layering. These processes require high-precision molds and have a high scrap rate. For example, the embossing process, the international The usual scrap rate in the world is 10%, and the scrap rate of coins with large diameter and large mirror surface area is as high as 50%. , and the engraving process requires the body to have a certain thickness, making the cost of these handicrafts high
