摘要
目的研究一种新的基础线性化算法,优化多级多色打印系统模型。方法分析现有的用于多级多色打印系统基础线性化算法存在的问题,并针对这些问题从多级墨量比例系数的确定、单通道控制、总墨量控制、网点级别转换和线性化等5个方面提出一种基于光谱的多级多色打印系统基础线性化模型。结果该方法的色域体积约为EFI流程控制的109%,在色域空间中的分布更加均匀,喷墨量约为EFI流程的50%~85%。结论新基础线性化算法在保证打印设备色域最大化的同时,可实现各基色墨水的最佳利用。
It aims to study a new basic linearization algorithm that can optimize the model of multi-level and multi-color printing system.The defects of existing basic linearization algorithm were studied by using the multi-level and multi-color printing system.A basic linearized model was put forward based on spectrum in such five steps as the determination of proportional coefficient in multi-level ink,single channel control,total ink coverage control,dot level conversion and linearization.The color gamut volume of this method was about 109% of EFI workflow.The distribution of spectrum in the color space was more uniform and the amount of ink was about 50%~85% of EFI workflow.In conclusion,the new basic linearization algorithm realizes the best use of each of the primary color ink while guaranteeing the maximum color gamut of printer.
