High definition, FM printing method, a way of high grade printing, was examined, and its physical characteristics, color difference, and characteristics of Lab color system were determined. Mainly aim of this study is to investigate high definition, FM printing method by color measurement. Compared to the 175 lines per inch of conventional printing method, high definition, FM printing method provided better chroma and resolving power considering its physical color measurement. Meanwhile, high definition printing method showed the increase of color difference according to the increase of screen ruling. However, no significant difference was found among FM printings dot size of 40-12.5μm This suggests that there is some limit for the effect of dot minimization. Value of color difference by sensitive expression, its value in between 175-300 lines per inch, 300-700 lines per inch indicate ‹noticable›, FM printing in between 40-12.5μm showed many ‹trace or slight›.
