Research on Color Consistency for Color Marketing in Network Transaction System Based on Color Management

Journal of Digital Information Management Volume 9 Number 6 December 2011 ABSTRACT: Color consistency is one of the key techniques for color marketing in color reproduction in network transaction system. A new color management method is presented based on analyzing the color rendering principles of scanned input images. Firstly, the method substitutes color blocks in color shade district in standard color target for complete color space to solve the difficulties of color sample selection. Secondly, contraction-expansion curve fitting algorithm is improved to improve its search efficiency and decrease its calculation. Thirdly, parameters of Yule-Nielson equation are reinterpreted, making them applied for non-printing dot image which only can be used for printed dot image originally and then the color conversion model for scanned images is deduced gradually though single color, double color and tricolor conversion correction. Finally the experimental results show that the model can improve scanner color conversion accuracy and can guarantee color consistency in color marketing in electronic business system in practice.
