| 目的 提出一种适于国内中小型印刷企业跟踪校正油墨预置曲线的方法。方法 首先分析了墨键开度曲线的特点， 建立了墨键开度曲线关系模型， 然后在校正曲线前印刷测试文件， 将测得的密度与标准值比较， 设定微调修正系数， 并对机器进行了相应调整。最后用Matlab软件对数据进行拟合， 得出与实验条件所匹配的四色墨键开度曲线， 同时标明了CMYK四色机组各自的墨斗辊转角值， 将曲线保存于墨控系统， 供后续印刷调用。 结果 找到了油墨预置曲线微调幅度和规律， 建立了进一步周期性微调校正的数学模型， 并通过实际生产验证了该方法的可行性。结论 校正后的曲线能够达到墨量预置快速准确的要求， 说明提出的校正方法具有实际意义。 |

| A method of tracking and correcting ink presetting curve applicable to the domestic small and medium-sized enterprises was proposed. The characteristics of the ink key opening curve was analyzed and the relationship model of ink key opening curve was established. And then the test file was printed before correcting the curve and the measured density was compared with the standard value, the fine-tuning correction coefficient was set and the corresponding adjustments was carried out to the machine. Finally the data were fitted by Matlab, obtaining the four-color ink key opening curve matched with the experimental conditions. Meanwhile, the fountain roller rotation angle of the four-color CMYK printing machine was marked respectively. The curve was preserved in the printing ink control system for later use. Fine-tuning range and the law of ink presetting curve were found, and the mathematical model for further periodic fine-tuning correction was established. The feasibility of the method was verified by practical production. The corrected curve was able to fulfill the fast and accurate requirements of ink presetting, demonstrating that the practical significance of the correcting method proposed in this paper. |
