1. The production process of aluminum sign board -- silk printing color anodized aluminum sign board

The advantage is: anodized aluminum signs, the surface is smooth and durable.

The anodized aluminum signs and panels are anodized and closed with a layer of oxide film on the surface to make the surface smooth and smooth. The usual ink screen often has poor adhesion, which should be noticed. To deal with this problem, it is necessary to deal with ink and operation problems first. Using alumina screen printing ink is the key to deal with the adhesion and robustness of the ink film in alumina screen printing. This ink is different from the general ink, it will be strong adherence to the aluminum plate, but also has a good light resistance, is a silk-printed aluminum anodizing sign of the ambition of ink.



2. aluminum sign board ‘s production process -- silk printing convex concave multicolored aluminum sign board

The convex-concave sign is characterized by the concave paint, it has good wear resistance, but also has a three-dimensional effect, more used in mechanical nameplates and corporate brands. The traditional method is to paint the corroded concave by hand (or inject the paint with a needle), and then trim it by hand to remove the edge residual paint. This method is not only time-consuming and low power, but also requires the operator to have skilled skills, and the produced signs often have unclear edges, distorted handwriting and unstable quality. Therefore, only limited to the production of some batches of small, color, quality requirements are not high, the image is very simple.
