Effect of Backgrounds with Different Lightness on the Color Appearance of Printed Samples

摘要

In this paper, the influence of neutral backgrounds with different lightness on color appearance was studied, five color centers and nine neutral backgrounds with different lightness based on printed samples were prepared. 20 observers were organized to carry out visual experiment with the method of paired comparison. The obtained experimental results indicate that the color appearance of color center is more affected by higher lightness backgrounds than the lower, which is quite different with the results computed by color appearance models (CAM). Furthermore, the factor of Standardized Residual Sum of Squares (STRESS) was used to evaluate the performance of CAM 16 and CAM02 model. The STRESS values show that CAM 16 (37.22) predicted more close to the visual results and performed well comparing with CAM02 (44.00).
