使用柔性版印刷配制和印刷功能模型油墨，以评估油墨拉伸弹性和印刷速度对印刷层的形态和电性能的影响。增加的拉伸弹性和更高的打印速度导致在印刷更各向同性打印，无论是形态学和电子。此外，印刷品的形态和电各向异性之间的相关性强烈表明印刷均匀性对功能性具有相当大的影响，并且油墨流变学可用于控制这些特性。
Functional model inks were formulated and printed using flexography in order to assess the influence of ink extensional elasticity and print velocity on the morphological and electrical properties of printed layers. Increased extensional elasticity and higher print velocity resulted in the printing of more isotropic prints, both morphologically and electronically. Furthermore, a correlation between the prints' morphological and electrical anisotropy strongly suggests that print uniformity has a considerable influence on functionality and that ink rheology may be used to control such characteristics.
