Abstract
A method of surface printing and electric plating, it is to perform pre-plating to form a pre-plated layer firstly on a surface of a metallic or non-metallic article to be plated, thereby the metallic or non-metallic surface will not be oxidized, and to perform printing and then electric plating to make the plated layer higher than the electric printed layer, thus an effect of 3 dimensions can be resulted; and the printing oil ink is protected in the plated layer, thereby it is not subjected to being stripped off by abrasion.
Claims3
A method of surface printing and electric plating consisting of the steps of:
- a) selecting an article made of a metallic material;
- b) pre-plating to form a metallic pre-plated layer directly on a surface of the metallic material without oxidizing the surface of the article and without requiring acid erosion;
- c) printing an oil ink directly on a first preselected portion of the metallic pre-plated layer to form a printed layer on the first preselected portion of the metallic pre-plated layer, the oil ink being a non electric conductive oil ink, the metallic pre-plated layer is located directly between the metallic material and the oil ink;
- and
- d) electrically plating a metal directly on a second preselected portion of the metallic pre-plated layer to form an electric plated layer, the second preselected portion of the metallic pre-plated layer being located adjacent to the first preselected portion of the metallic pre-plated layer, the metal of the electric plated layer being located adjacent to the printed layer and the metal of the electric plated layer having a thickness greater than a thickness of the printed layer;
- wherein, in the pre-plating step b), the material of the metallic pre-plated layer is selected from a group consisting of nickel, half glossy nickel, and copper.
