| 目的 为提高光柱镭射纸上专色配方的精确度，探究光柱镭射纸上基础油墨数据库的建立方法。方法 验证加入“垫黑”基础油墨数据库前后对目标色和预测色之间色差和均方根误差的影响，并将配色软件应用于生产实际中。结果 研究结果表明，没有经过“垫黑”处理的基础油墨数据库导致配色不准确，出现颜色偏移现象。配色软件基于“垫黑”和“垫白”的基础油墨数据库能够精确配制光柱镭射纸上的专色，初始配方、修正配方的色差平均值分别为3.1888和1.7711，色差皆降至3以下;初始配方、修正配方的均方根误差平均值分别为0.0380和0.0256。结论 专色配色需考虑承印物的表面特性差异，从而建立不同的基础油墨数据库。在配制光柱镭射纸上的专色时，爱色丽配色软件需要“垫白”和“垫黑”的光柱镭射纸基础油墨数据库，否则无法实现精确配色。 |

| 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. |
