摘要
彩色屏幕地图是以R、G、B色空间表示 ,彩色印刷地图是以Y、M、C、BK油墨色空间表示的。因此彩色屏幕地图输出成为印品必须经过色空间的转换。黑版的确定是色空间转换的难点。文中论述的是在Neugebauer三色转换方程的基础上 ,经过大量实验获得的一种黑版确定的方法。
Since color screen map is displayed in R,G,B color space and color printing map is displayed in C,M,Y,BK color space, we have to transfer the color information between two color space when we want to export the screen map to printing map. How to calculate the gray component is the most difficult job in color space transferring. This paper discusses the method to calculate the gray component based on three colors Neugebauer equation.
