The invention discloses an improved method for screen printing two-dimensional code platemaking. The method comprises the following steps of (1) black and white color inversion treatment is conducted on a two-dimensional code graph, and then platemaking is conducted, so that white ink can penetrate through a blank area and a binary data '0' area in the two-dimensional code graph; and (2) an edge patrolling area and a binary data '1' area in the two-dimensional code graph are complemented in cooperation with the color of a black product, and then the 'white background black code' effect is achieved on the surface of the black product. On the basis of not increasing production procedures and not changing a printing method, printing of the two-dimensional code with the 'white background black code' effect is achieved on the surface of the black product, the two-dimensional code can be recognized by most common code scanning devices, a special portable data collector is not needed, the acceptance cost of factorie
