Abstract – The perceived glossiness of 12 flat samples and 18 bumpy samples with various colors and gloss levels is estimated by 13 observers using magnitude estimation technique. Each sample is measured with the gloss-meter as well. It is found that bumpy surface shows lower measured gloss level than flat surface treated with the same level of UV coating. The perceived glossiness of bumpy surface is higher than that of flat surface with low level UV coating treatment while perceived glossiness of bumpy surface is lower than that of flat surface with high level UV coating treatment.
