So it is necessary to know the relationship between the paper`s performance and color effect .And we can be reasonable to select paper based on the product and printing technology. This is meaningful to improve the product quality. This issue discusses the relationship between the paper`s performance and the color gamut..The samples of offset paper and chrome paper were chosen and measured ,including whiteness, smoothness gloss and absorbability. And the two samples were printed with the same printing machine. The tristimulus values (X,Y and Z) of solid areas were tested. Chromatic diagram were drawn after data analyzing and processing ,and then the influence of paper performance on gamut of color was analyzed. The result shows that greater color range occurred because of higher smoothness, gloss ,whiteness and lower absorbability to chromatic paper when the printing conditions were definite . Key Words: Paper performance; XZY tristimulus values; chromatic coordinates;color range
