In order to investigate effect of caul plate gloss on glossiness of high-gloss laminate flooring,high-gloss laminate floor samples were prepared with caul plates having different gloss levels.Roughnesses and atomic force microscope （AFM） images of the samples were observed. Results showed that the roughness of the samples increased and the gloss decreased as the caul plate gloss decreased;3D-AFM images of the samples indicated that the glosses of the samples were closely related to caul plate gloss. Dents and protrusions on the sample’s surface occurred when caul plates with lower gloss were used and also resulted in a poor gloss surface on the flooring samples.
