数字彩色像纸的照片品质控制

Print Quality Control of Digital Color Photographic Paper

进入21世纪以来,数字照像在我国迅速推广、普及,普遍采用的方法是用数码相机拍摄,然后由专门的照像加工点用数字彩色像纸印成彩色照片。有别于传统的照像方法,数码照相机是用CCD或CMOS传感器记录影像的,在用彩色像纸印制时,可以由数码相机传感器储存的信号转换成对数字彩色像纸曝光的调制光,简化了整个成像过程,而且可以直接采用光能极强的激光代替传统的三原色印片光,大大加快了印片过程。本文针对数码彩色照片印片、冲洗加工过程的品质管理作了一个理论结合实际、全面而详细的阐述。

Since the new century,digital photography has been blooming in our country. Generally,people use digital cameras for shooting,and color prints are made by special photographic processing service using digital color photographic paper.In digital cameras,images are recorded by CCD/CMOS sensors,the stored signals may be used for directly monitoring the exposure of digital photographic paper and allow the use of high intensity laser beam instead of the conventional triprimary color beam normally used in traditional printers ,thus speed up the printing process. This paper presents a comprehensive,detailed and practical elucidation of the color print quality control process using digital color photographic paper.
