Abstract
The increasing use of newsprints in the media and an advertisement have brought the needs to improve the printing quality of the advance full-color newspaper. The printability coefficients used in this research such as Ymax for the density and Tollenaar's density smoothness constant value $\ulcorner$m$\lrcorner$ were introduced early in Europe and have been in use to control printing quality. In order to improve printing quality of domestic full-color newsprints, those printability coefficients could be used to control printing quality. This study was carried out to measure the printability coefficients of domestic full-color newspapers. Four kinds of domestic newspapers and two kinds of newspaper printing inks were tested by IGT printability tester. The printed density smoothness coefficient $\ulcorner$m$\lrcorner$ value showed good results when the samples have low porosity and roughness. The printability coefficients obtained are expected to be useful to the korean newspaper printing industry.
