Influence Analysis of Color Input Target to the Scanner Color Characteristic

摘要

Scanner is the indispensable image acquisition equipment in the prepress system, high quality ICC profile is significant to reflect the color expression of scanner, and the character of ICC profile is influenced in a great extent by the color input target. The subject is to set up the ICC profile by scanning and data processing Kodak IT8.7/2, Goldencolor GCT 3.0 and GretagMacbeth ColorChecker SG, get the influence of each color input target to the scanner color characteristic through the accuracy analysis and color gamut comparison. Research shows that three kinds of color target has its own advantage, Kodak IT8.7/2 has big color gamut, high accuracy, and better reappearance ability, meets the needs of the everyday users; GretagMacbeth ColorChecker SG is good to the reappearance of high saturate manuscript, and its precision is high, applying to recreate natural landscape; Glodencolor GCT 3.0 is of high precision and larger color gamut, but its expression ability is not good enough in the section of high saturation red and magenta, it can produce high quality scanner ICC profile also. Consequently, it should be taken into consideration of the manuscript, color gamut, accuracy and cost-effective factors comprehensively when choosing scanner color target, eventually you get a satisfactory scanning result.
