The invention discloses shadow copying paper and a processing method. The method comprises the following processes: performing wet beating on commercial pulp serving as a raw material by adopting two-stage pulping and a double-millstone abrasive sheet to make the brooming rate of pulp fibers reach over 20 percent and reach high strength and strong water permeability resistance of paper; and performing a papermaking step with the pulp, namely adding water impermeable fluorine-containing copolymerization emulsion in an innovative U-shaped three-layer polyester net, adding papermaking-grade CMC in the production flow to perform retention aid, quantifying the formed and dried product at 16+/1 g/m<2>, and controlling the water permeability to be less than or equal to 2.5 millimeters so that the product has the characteristics of writing breakage resistance, water permeability resistance, high definition and myopia prevention. The method produces the special shadow copying paper by using the commercial pulp as the raw material, combining the novel S-shaped double-millstone abrasive sheet and the innovative U-shaped three-layer polyester net, adding the water impermeable fluorine-containing copolymerization emulsion and combining the preferred fiber degradation chemical enzyme.
