Abstract

The invention provides a spherical curved surface printing process. The process is characterized in that a spherical curved surface base material is sprayed with a preprocessing layer, then a printinglayer is applied to the surface of the preprocessing layer, finally the printing layer is sprayed with protective layers. The affinity of the printing layer and the spherical curved surface base material is improved by applying the preprocessing layer to the spherical curved surface base material, then the printing effect is improved, and the protective layers are applied to the printing layer, so that the wear resistance and the weather resistance of a printing product are improved; and products prepared by the process, such as sport competition balls, can keep marks on the surfaces of the balls with good wear resistance, stripping resistance and durability, and can keep long-term use without scratching, fading and falling.
