Abstract: SEM was used to study physical properties of bronze powder in intaglio printing. Its microphotograph,size distribution,thickness and behavior in oil ink were mainly investigated. The results indicate that the imported bronze powder whose surface is clean has the narrow distributions of particle size. The domestic particles with wide size distribution contain a large proportion of too small powders, which reduce its metallic gloss. The thickness of imported products is about 0.1μm and the radio of diameter to thickness is 50,but the thickness of national ones ranges from 0.1 to 0.3μm and the radio of national ones is 40. The thinner the flakes are,the more excellent water surface covering power is. Dire ctional arrangement of bronze powder in printing ink was observed,which has a impaction on optical property.

Abstract:
SEM was used to study physical properties of bronze powder in intaglio printing. Its microphotograph, size distribution, thickness and behavior in oil ink were mainly investigated. The results indicate that the imported bronze powder whose surface is clean has the narrow distributions of particle size. The domestic particles with wide size distribution contain a large proportion of too small powders, which reduce its metallic gloss. The thickness of imported products is about 0.1?μm and the radio of diameter to thickness is 50, but the thickness of national ones ranges from 0.1 to 0.3?μm and the radio of national ones is 40. The thinner the flakes are, the more excellent water surface covering power is. Directional arrangement of bronze powder in printing ink was observed, which has a impaction on optical property.
