The evaluation method for Surface checking of face veneer was presented in this paper. The gauge on the veneer could be used to measure the width of surface checking with the 90-time-microscope and microcamera. By measuring the three specified lines all the surface checkings were tested and their average width and standard deviation could be used to evaluate the quality of surface. Based on the test, the relation was analysed between the surface checking of face veneers and that of painting. The application results of the method also show that it is feasible.
