インクジェット印刷における印字品質の評価 Study of Evaluation of Print Quality on Ink-Jet Printing
In general, print quality of ink-jet printing is dependent on physical properties of ink and substrate. In this study, print quality was evaluated using three kinds of substrate, i.e., two kinds of coated paper with different coated layer thicknesses and PPC paper by applying dye based ink at the same speed as the practical printing process. Jetting phenomenon was investigated by the Jet Formation Monitoring System and the effects of scanning speed of print head were investigated by Dynanic Simulator. Print quality was evaluated by three parameters of the dot, i.e., dot spreading on the substrate, fractal dimension and optical density of the dot. As the result, the relationship between the properties of the substrate and these parameters which are dependent on penetration phenomenon was obtained. Furthermore, we are proposing the Triangle Method which combines these three parameters to evaluate the print quality. By this method, we can obtain useful information for quantitative evaluation of print quality.
