| 目的 研究密度叠印率与其叠印色差的关系， 并尝试确定密度叠印率合格标准。方法 理论推导求解网点百分比叠印率与叠印色差的量化关系， 理论推导网点百分比叠印率与贝雷斯叠印率的量化关系，并通过Excel进行数据分析与计算。结果 当第2色实地密度为1.5时， M/Y， C/Y， C/M的贝雷斯叠印率合格标准分别大于或等于70%， 73%， 86%。结论 网点百分比叠印率与色差呈近似线性反比关系， 密度叠印率受多种因素影响， 叠印率合格标准仅在特定条件下有效。 |
| 英文摘要: |
| This paper mainly studied the relationship between density trapping rate and chromatic aberration, and try to determine qualified standard of density trapping rate. The quantitative relationship of the dot percentage trapping rate and trapping chromatic aberration was deduced and solved through the theory way, the quantitative relationship of the dot percentage trapping rate and Preucil trapping rate was deduced theoretically, and data analysis and calculation were conducted by Excel. When the second color field density was 1.5, the M/Y, C/Y, C/M trapping rate eligibility criteria were greater than or equal to 70%, 73%, and 86%, respectively. Dot percentage rapping rate had approximately inversely linear relationship with chromatic aberration. The density trapping rate was affected by many factors, and the trapping rate qualified standard was effective only under specified conditions. |
