摘　　要：给出了自动色彩检测和控制系统的工作原理,在分析了密度等质量参数与输墨量之间的关系、色度与密度之间的变换矩阵的基础上,设计了基于密度的色墨转化算法及基于色度的色墨转化算法,并给出了相应的算法流程.将该算法应用到色彩检测和控制系统中,当检测仪器检测到密度或色度偏差时,自动计算出墨斗各墨键的调整值,以实现输墨量的改变,进而实现色彩的校正,提高印刷品的色彩质量.Color measurement and control system can improve the product quality and efficiency of multi-color offset printing,and the technology of color to ink conversion is one of the key technologies of the color measurement and control system. First,the principle of the automatic color measurement and control system is given,then,the relationship between the quality parameter,such as the density,and ink amount is analyzed,and the conversion matrix between chroma and density is given. On the basis,color to ink conversion algorithm based on density and color to ink conversion algorithm based on chroma are designed,and the relevant algorithm flow diagrams are given. The algorithms are applied to the color measurement and control system. When there is density deviation or chroma deviation,the algorithms can calculate the adjustment of the ink key automatically to change the ink amount,then improve the color quality of the print.
