DNP Rheology and Flow Characteristics of Intaglio Inks S. Shinozaki, H. Yamaguchi, T. Suzuki, E. Miyata and M. Aritomi DNP Fine Chemicals Co., Ltd. ABSTRACT: On the basis of the flow behavioral analysis of offset inks, we found that factors (Yield, Viscous and Modulus terms) controlling the fluidity of offset inks and three power indexes(m,n and p) of our flow characteristic formula(formula ) are different at the share rate range from low to high. Sm n Gp S: Yield term : Viscous term G: Modulus term ; (m+n+p=1) We have tried to analyze mottling phenomena affecting significantly the printing quality of intaglio printings by using the rheological analysis. The mottling has been estimated quantitatively by using the digital image analysis, and also Yield, Viscous and Modulus terms have been measured and contribution ratio has been calculated.
