基于印刷原稿的扫描仪色彩管理的研究

为了研究和解决扫描色差问题,本文按照ICC制定的开放式色彩管理标准,采用一元线性回归算法建立扫描仪色彩修正文件,实现了基于印刷反射稿的扫描仪色彩管理。研究中将原稿各实地色块的实测L＊a＊b＊值与经过扫描仪扫描后得到的L＊a＊b＊值进行比对,在此基础上采用一元线性回归的方法进行拟合,并通过分析不同纸张对扫描颜色偏差的影响,建立扫描仪的色彩修正模型;同时完成对3台不同扫描仪的色彩修正,开发出相应的扫描仪色彩管理软件。研究结果对入门级色彩管理的普及应用以及应用水平的提高都有促进意义。

Research on Color Management for Scanner Based on Printed Original

In order to solve the problems of the color management of the scanners,according to the open color management standards developed by the International Color Consortium（ICC）,simple linear regression model was used to establish the color calibration profile of the scanners,and then the color management of scanners based on the reflex copy was achieved. In the study,on the basis of the contrast between V~＊ a~＊ b~＊ values measured and scanned from the print,simple linear regression was used to fit.By analying the effect of the paper properties on the color difference,the color calibration model of scanners was established,and the color calibration of three different scanners was completed.Ultimately the color management software was finished.The results have a promotion for the universal application of the rudiment of color management and the raising of application level.
