Classification of common metal signs, common metal signs include flat signs, silk screen signs, corrosion signs, electroplating, electroforming signs, thermal transfer signs and sandblasting signs.

(1) Flat signage: Using the method of photosensitive signage, different colors are dissolved into the film, so that they are displayed on the metal plate by the method of development, so as to achieve the purpose of descriptive significance.

(2) Screen printing signs: Using resin inks, screen printing is performed on the pre-treated board surface, and then various delicate color screen printing signs can be made by processes such as gloss preservation and lamination.

(3) Corrosion signs: Corrosion signs are also etching signs. Mainly check the embossed sign or concave sign made by three steps of masking and post-etching treatment.

(4) Electroplating metal signs and electroforming signs: also known as gold pile signs, which are made by screen printing or photosensitive

(5) Thermal transfer metal sign: It is a special panel generated by the surface treatment process of the metal plate, and then the color picture you designed is printed on the transfer paper by inkjet printing, and reversed by heating onto a metal plate, made of signage.
