Production method of single-ground-color graph code steel plate integrating roller painting and screen printing

The invention provides a production method of a single-ground-color graph code steel plate integrating roller painting and screen printing. The screen printing and the roller painting printing are combined so that accurate ground color patterns can be obtained, and a thick printing layer which is strong in stereoscopic sensation can be obtained, and meanwhile, a servo control system is added to a roller painting section. The servo control system is used for controlling the rotation speed and starting time of each roller in a roller painting equipment component so that consistency of actual roll surface linear speed and craft rotating speed is ensured, and therefore stop line adjustment is not needed in the process of production, and production efficiency is improved.
