In order to improve the accuracy of the spot color formula on the holographic paper, the method of establishing the basic ink database on the holographic paper was explored. In this paper, the influence of adding "black backing abase without "black backing backing backing holographic paper. The average color difference of the initial formula and the modified formula is 3.1888 and 1.7711 respectively. The color difference is below 3. The root mean square error of the initial formula and the modified formula were 0.0380 and 0.0256 respectively. Spot color matching needs to take into account the differences in the surface properties of the substrate, thus creating a database of different base inks. When preparing spot color on holographic paper, ink formulation system needs "white backing backing herwise, accurate color matching cannot be realized.
