Zusammenfassung: | To provide a printed result prediction method and a printed result prediction system in an inkjet printer.SOLUTION: A printed result prediction method in a printing device that forms a plurality of ink dots by making ink droplets impact on a printing medium includes: a step of predicting ink droplet-impacting positions on the printing medium; a step of predicting a film thickness distribution of ink droplets on the printing medium on the basis of shapes of the ink droplets impacting on the predicted impacting positions; and a spectral reflection factor predicting step of predicting a distribution of spectral reflection factor of the ink droplets on the printing medium on the basis of unit spectral transmittance per unit thickness of the ink droplets on the printing medium, the film thickness distribution, and reflection characteristics of light from the printing medium. The step of predicting a film thickness distribution, when the plurality of ink droplets impacting on the predicted impacting positions interfere with each other, predicts shapes of the ink dots on the printing medium on the basis of dot diameters of the ink droplets, impact distances of the ink droplets and difference in discharge time of the plurality of ink droplets, and then predicts the film thickness distribution on the basis of the predicted result.SELECTED DRAWING: Figure 1
【課題】インクジェットプリンタにおける、印刷結果予測方法と印刷結果予測システムを提供する。【解決手段】印刷媒体上にインク滴を着弾させて複数のインクドットを形成する印刷装置における印刷結果予測方法であって、印刷媒体上におけるインク滴の着弾位置予測工程と、予測着弾位置に着弾したインク滴の形状に基づいて、印刷媒体上におけるインク滴の膜厚分布予測工程と、印刷媒体上におけるインク滴の単位厚み当たりの単位分光透過率と、膜厚分布と、印刷媒体からの光の反射特性と、に基づいて、印刷媒体上におけるインク滴の分光反射率の分布を予測する分光反射率予測工程と、を含み、膜厚分布予測工程は、予測着弾位置に着弾した複数のインク滴が干渉し合う場合、インク滴のドット径、インク滴の着弾距離、および複数のインク滴の吐出時間差に基づいて、印刷媒体上におけるインクドットの形状を予測し、その予測結果に基づいて、膜厚分布を予測する。【選択図】図1 |
