The most commonly used electric advertisement boards printed inside are electric screens printed on the inside of an acrylic board, and finally printed in solid white, and the surface of the board can be formed into a glossy decorative pattern. If the light inside disappears, light from other directions will reflect on the surface and various colors will appear.
In the case of surface printing, milky white translucent plates are generally used. Since all-white printing is not required, uneven quality rarely occurs, but scratches are easily generated on the surface.
When shading, it can be printed in two ways. If the surface is intended to be shaded with full red, the same plate may be used for shading purposes before the full red color is printed, silver or gray is printed, and then full red is printed on top. When the electric decoration is performed, only the text or the pattern part is highlighted, which is very clear and beautiful, so it is often used for the printing of road signs or guide plates.
In the case of acrylic printing, the material itself is highly charged due to its electrically charged nature and it is easy to adhere to dust.
Since dust adheres to the electrical panel very clearly, in order to eliminate dust and prevent static electricity, alcohol is used to wipe the substrate once before printing. Because the light is emitted from the inside, the printed scratch marks are also very noticeable. For this reason, great attention is paid to the grinding of the squeegee, the printing pressure, the printing speed, etc., and uneven printing should be minimized. Due to the use of a good light-transmitting ink, after printing and electro-decoration, the tinge of a person's tone seems to have changed completely.
When combined with other colors, it is possible to make products that differ from the customer's requirements if light transmission is not observed. In the case of four-color printing, if the color is adjusted without light transmission, a very light and blurred image may be formed.
