신문용지의 인쇄적성 계수에 관한 연구 (제2보)-최대 잉크 색 농도(D∞), 색 농도 평활성 계수「m」값-

초록

Uneven ink transfer of a print can be traced to several causes such as an incomplete contact between the paper surface and ink film, a coarse pattern of a continuous ink film after transfer, uneven absorption, etc. Uneven ink transfer was studied in this points by the Tollenaar. Uneven distributions of printed density are reflected in low 「m」values of the print. Tollenaar's smoothness coefficient「m」value was important factor that deciding printed quality which was easily obtain by densitometry. Limiting print density D∞ that obtained Tollenaar's formulation working as a influence factor at the printed quality. In this study, we obtained limiting print density D∞ and smoothness coefficient「m」value of domestic newspapers and foreign newspapers. And we analyzed about properties of the newspaper. The result of this study, smoothness coefficient「m」value and limiting print density D∞ showed the good results in the low porosity and low roughness newspaper. Datum which obtained by this study used as printability factor for the quality control and improve of domestic newspaper and wished to apply as a basic data for the domestic newspaper quality.
