3.1 Seediness: film is with rough surface, particles or impurities.
3.2 Color difference: for the same product, its parts are respectively different in color.
3.3 Uniform color and luster: surface of the same part is uniform in color.
3.4 Sagging: vertical to the surface of object, the paint flows down before drying, which makes the thickness of dried film uneven and leaves flow mark on it.
3.5 Favorable light: for natural light, its luminance is 400~700 lx; for approximate natural light, its luminance corresponds to that of 40W fluorescent lamp which is 500~700 mm away from the sample.
