摘要
采用IGT模拟平版印刷的实验,建立了3种墨层厚度与光学密度的转换模型,依据模型的MAE和RMSE值,采用T-E模型,获得了多种油墨纸张组合的最佳墨层厚度范围。通过v4插值算法建立了CCD响应值与墨层厚度范围的三维模型,以实现墨量在线检测,并以测试样张的CCD响应值是否对应于最佳墨层厚度范围,验证了模型的准确性。
Three kinds of ink film thickness and optical density conversion model were established through simu- lating offset print with IGT. According to the MAE and RMSE values, by using Tollenar-Erns model, the best range of ink film thickness of different paper and ink＇s combination were solved. A three dimensional model of CCD signal acquisition values and ink film thickness was set up by using v4 interpolation algorithm to realize ink on-line testing. The model＇s accuracy was validated by testing sample＇s CCD signal acquisition values on the correspondence to the best range of ink film thickness.
