Lake Red C 안료의 표면적과 용매함량이 인쇄잉크의 물성에 미치는 영향

In this work, we have investigated the printability such as print through and str-off of domestic newspapers. Nine kinds of domestic newspapers Hansol, Deahan, Sinho, Hanla and Sepung, were tested by IGT printability tester, and studied using maximum ink requirement method. We obtained the datum of printability parameters such as maximum ink requirment of paper Ymax, printing density D, print through, set-off and gloss. The results of this test showed that a choice of the fillers on the newspaper had an effect on print through, set-off and density of newspapers in the maximum ink transfer point.
