Abstract
Printing is the technique for reproducing many copies of a graphic message. Accurate reproduction of color is an important parameter to evaluate the quality of printing. In the current offset printing industry, six-color press still occupies a large market share. For six-color offset press, when the Pantone colors are more than six it is difficult to accurately reproduce all colors. In this paper the solution of printing C, M, Y, K four primary colors and two spot colors is proposed. When this method is applied to an eleven colors artwork, color differences for main colors are below 3, for the auxiliary colors are below 15, especially some difficult auxiliary colors the average color differences is reduced by 59%. It is demonstrated the method can effectively control the color difference and make all Pantone colors reach the industry standard or customer’s requirement. Therefore, it can achieve accurate color reproduction of multiple pantone color by the six-color press.
