Embodiment 1
[0015] Embodiment 1: This metal surface shadow etching special effect process mainly includes the following steps:
[0016] (1), the metal plate is surface-leveled and cleaned, and the basic figure that needs to be etched is selected; the anti-corrosion printing material is printed by silk screen at the place complementary to the basic figure, so that there is no anti-corrosion printing material on the basic figure;
[0017] (2) Etch the basic pattern on the metal plate by chemical etching or electroetching, and the depth is controlled between 0.2-0.4mm;
[0018] (3), select the texture graphics that need to be etched inside the basic graphics, and print anti-corrosion printing materials by screen printing at the places complementary to the basic graphics and texture graphics, and texture graphics and figurative patterns can be made according to design requirements. Or make dot graphics.
[0019] (4), by chemical etching or electroetching, etch the texture pattern, the depth ...
Embodiment 2
[0023] Embodiment 2: The difference from Embodiment 1 is that the steps (3) and (4) are repeated after the step (4), and the secondary texture pattern is etched inside the texture pattern, and the depth is controlled at 0.1-0.2 Between mm, the depth is based on the texture graphic plane after etching, so that the surface of the metal plate presents three levels, and so on, up to four levels.
