The invention relates to an ultraviolet-proof printing method for a light and thin fabric. The ultraviolet-proof printing method comprises the steps of rolling of grey cloth, pretreatment of the rolled grey cloth, pre-setting, printing with ultraviolet-proof paint, drying, baking and setting. According to the ultraviolet-proof printing method, the ultraviolet-proof component is added into printingcolor sizing, and while elegant patterns are printed, ultraviolet-proof performance is endowed to the fabric. On the one hand, the patterns and the ultraviolet-proof function are endowed to the fabric through one-step technology, and the creativity is original; on the other hand, the technology is simple, energy conservation and environment protection are achieved, and the cost is reduced. The fabric prepared by using the method has good application prospects in the fields of umbrella covers, down jackets, surgical gowns and cleanroom garment for foods, pharmacy and precise electronics.
