We propose an efficient framework with compatibility between normal printing and printing with special color inks in this paper. Special color inks can be used for printing to represent some particular colors and specific optical properties, which are difficult to express using only CMYK inks. Special color layers are required in addition to the general color layer for printing with special color inks. We introduce a reversible data hiding (RDH) method to embed the special color layers into the general color layer without visible artifacts. The proposed method can realize both normal printing and printing with special color inks by using a single layer. Our experimental results show that the quality of the marked image is virtually identical to that of the original image, i.e., the general color layer.

可逆数据隐藏在特殊颜色墨水打印中的应用，以保持与常规打印的兼容性

我们提出了一个有效的框架，该框架在普通打印和使用特殊颜色墨水的打印之间具有兼容性。特殊颜色的墨水可用于打印以表示某些特定的颜色和特定的光学特性，而仅使用CMYK墨水很难表达。除了用于使用特殊颜色油墨进行打印的常规颜色层之外，还需要特殊颜色层。我们引入了可逆数据隐藏（RDH）方法，将特殊颜色层嵌入到常规颜色层中而没有可见的伪像。所提出的方法可以通过使用单层来实现普通打印和使用特殊颜色的墨的打印。我们的实验结果表明，标记图像的质量实际上与原始图像（即普通颜色层）的质量相同。
