Abstract: The required appearance quality of tinplate, coating plates and decoration steel plates that is determined by light physical
effects of steel strip micro-topo raphy. The required appearance quality includes color, reflection characteristics, texture, clearness of
imaging, uniformity and edge sharpness. Glossiness is used as a criterion to assess the appearance quality of tinplates that are related
to the microstructure of the steel plate surface such as brightness uniformity, graphic distortion and edge blur when printing on the
packing tinplates. The relation between glossiness, which is an optical property of a surface, and the parameters that characterize the
geometrical properties of the surface is derived from the basic principle of glossiness measuring, thus the impact of the variations of
R and P on glossiness is illuminated. The mathematical correlation between glossiness and the geometrical parameters of tinplate is
established by the stepwise regression on the lield measured dala during batch industrial production, thus how the variation ol
glossiness with Ra and P is concluded. The correlation is verified by the statistic model OT produclion test. Ihus, the
glossiness is replaced by the control of R and P which is more feasible in tinplate producing. This study proposed a solution and
control techniques for the manulacturing process of glossiness qualilied tinplate. It is adoptcd by a factory and the qualificd ralc of' its
