| 目的 探究荧光增白剂对纸张印刷色彩管理的影响。方法 选择2种300 g/m2定量的日本富士施乐彩激纸， 一种含有荧光增白剂， 一种不含荧光增白剂， 使用KONICA MINOLTA C6000打印机输出色块， 测量色彩管理前后2种纸张输入和输出色块之间的色差。对比2种条件下输出色块与输入色块的色差， 分析荧光增白剂对不同阶调和墨层厚度的色块的输出影响， 并探讨UV-cut滤镜对荧光增白剂的校正效果。结果 在D50光源下， 含有荧光增白剂的纸张较不含荧光增白剂的纸张输出颜色的色差大。荧光增白剂对中间调颜色的影响大于亮调和暗调颜色， 对颜色的影响程度与亮度值呈正比， 与墨层厚度呈反比。荧光增白剂对亮调颜色 b值的影响大于暗调颜色， 荧光增白剂对颜色的 a值影响不大。结论 含有荧光增白剂的纸张上输出的色域体积要小于不含荧光增白剂的纸张， 对颜色的控制也较不含荧光增白剂的纸张差。使用UV-cut滤镜对荧光增白剂进行校正后纸张上输出色块的色差减小， 对准确在纸张上进行颜色再现具有重要意义。 |

| The aim of this work was to explore the impact of Optical Brightening Agents on paper printing color management. Two type of Japanese Fuji xerox color papers of 300 g/m2 were chosen, one with Optical Brightening Agents, the other without Optical Brightening Agents, and KONICA MINOLTA C6000 printer was used to output colors, then the color differences between the input and output on the two kinds of paper before and after color management were measured. The color differences under the two conditions above were compared and the impact of Optical Brightening Agents on different tones and ink layer thickness of output colors was analyzed. In addition, the correction of UV-cut filter on Optical Brightening Agents was discussed. The paper containing Optical Brightening Agents output a larger color difference under D50 light source. The influence of fluorescent brighteners on midtone colors was greater than those on bright and dark color tones, while the impact on colors decreased gradually with the decrease of color brightness and the increase of ink film thickness. The impact of the Optical Brightening Agents on the bright color b value was greater than that on the darkened color. The impact of the Optical Brightening Agents on the a value of color was not obvious. The gamut volume of the output color on paper containing Optical Brightening Agents was less than that on paper without Optical Brightening Agents, and the color control ability of paper containing Optical Brightening Agents was greater than paper without Optical Brightening Agents. The difference of output color was reduced after the correction on Optical Brightening Agents with UV-cut, which was significant for copying colors accurately on paper. |
