Yellow Color Acquisition of Old Yellowed Book Based on Color Management with Small Color Gamut

Abstract

The existing scanning device mostly adopts the standard color cards with large color gamut for color management. It is difficult to accurately acquire the yellow color of old yellowed books. This study aims to establish a color management method based on small color gamut to achieve an accurate recording of the yellow color of old books. The color values of old books are collected first. Then a standard color card with small color gamut that can cover the yellow color of the book is prepared. The standard color card is utilized as a tool to perform color management on scanning device, realizing an accurate collection of the yellow color. The experimental results show that the color difference between the yellow color acquired and the actual color of the book is significantly smaller than that of color management with large color gamut. This method can also be applied to color management of products such as bronze, ceramics and wood.
