| 中文摘要: |
| 目的 研究 Photoshop 中转换选项对印前分色的影响。方法 首先对 Photoshop 中转换选项的基本原理进行阐述， 并组合不同转换选项设置， 进行印前分色测试， 然后对测试结果进行主观和客观的评价。结果 未进行黑场补偿的转换设置， 暗调层次并级严重； 不同再现意图中， 相对比色再现意图转换后色差平均值及色差标准差均为最小， 感知再现意图色域范围最广。结论 每个转换选项对印前文件的层次和颜色转换均有其适应性映射目的， 用户需要在了解其基本原理及作用的条件下，根据原稿的类别或者使用偏好来选择。 |
| 英文摘要: |
| The aim of this study was to investigate the influence of conversion options in Photoshop on pre-press colour separation. Firstly, the basic principle of the conversion option in Photoshop was explained, and different conversion option settings were combined to conduct the pre-press color separation test, and then the test results were evaluated subjectively and objectively. Without conversion setting of black point compensation, tone merged seriously in shade area. Among the different colorimetry rendering intents, relative colorimetric rendering intent conversion had the smallest average value and standard deviation of color difference, while perceptual rendering intent had the widest color gamut range. Each conversion option had its own adaptive mapping purpose for the level or color conversion of the pre-press file. Users need to understand the basic principle and function before setting the conversion options according to the original pattern or the user preference. |
