    Abstract: A preparation method comprises: preparing a green body using green body powder; applying an overglaze on the surface of the green body; ink-jet printing a pattern on the surface of green body; applying a protective glaze on the surface of the green body; applying an anti-counterfeiting material on the surface of the green body; firing the green body, titanite and high-refractive-index oxide being wetted and wrapped by a molten liquid produced by melting a low-temperature glaze powder in a firing environment, and sunken into the protective glaze without generating opacification; and then polishing to obtain a ceramic plate having an anti-counterfeiting visual effect. The anti-counterfeiting visual effect is a visual effect in which a high-intensity refraction effect is achieved when the sight line direction is consistent with the path of reflected light, but no refraction effect is achieved when the sight line direction deviates from the path.
