| 目的 研究使用CMYK四色复制品牌色时品牌色颜色宽容度的评判方法和可复制百分比。方法 从ICC色彩管理流程着手，研究色彩转换过程、复制过程及测量仪器之间的色差，结合视觉理论给出评定品牌色复制性颜色宽容度的影响系数及数据。结果 品牌色可复制性评判的颜色宽容度为3.5∆E00，指定ICC Profile转换的品牌色可复制比例分别为65%（CGATS21-CRPC5）, 74%（CGATS21_CRPC6）和86%（CGATS21_CRPC7）)。结论 所提出的判定品牌色可复制颜色宽容度方法可以给印刷标准单位用来定量评价品牌色在不同四色印刷条件的可复制百分比。 |
| 英文摘要: |
| The work aims to study how to determine the tolerance for brand color reproduction and the %Reproducible Pantone Colors of CMYK device. Beginning with the ICC-based color management workflow, the color difference among the color conversion process, reproduction process and measuring instrument was studied. Combined with the theory of vision, the influence coefficient and data used to determine the color tolerance of brand color reproduction were given. The tolerance for brand color reproduction was 3.5∆E00. The reproducible Pantone colors in CGATS21_CRPC5, CGATS21_CRPC6 and CGATS21_CRPC7 printing con-ditions converted by designated ICC Profile were 65%, 74% and 86%, respectively. The proposed method for determining the brand color reproduction tolerance can be used by a printing standardization body to quantitatively evaluate the reproducible brand colors of any color output device. |
