| Detecting of the printer's characteristics plays an important role in Color Management System (CMS). In viewing of the disadvantages that printer's color characteristics can not be measured automatically and the low efficiency of the measuring method at present,3-CCD-based measuring technique is proposed.The feasibility of using CCD-scanner substitute spectrophotometer is discussed. The error of colorimetric measurement using CCD-scanner is studied. The calibration methods using polynomial regression are implemented. After analyzing the results of experiment using present scanner-calibration method, an advanced calibration target is acquired. At last the result of the experiments are given. The results indicate that the advanced scanner-calibration method not only improve the precision of scanner-calibration more, but also efficiently improve the reliability and the automation in detecting the printer's color characteristics meeting the demand of precision. |
