摘要
在基准印品和待检印品配准的基础上,建立颜色空间转换模型,将图像的RGB值转换为色度值,并计算对应点色差,利用色差对印品颜色质量进行判定。
Color space conversion model was established based on the registration of printing mater and standard printed mater. RGB Value was converted to chroma value with the model, and the color difference of the corresponding points was calculated. The color difference was applied to evaluate the color quality of the printed matter.
