Pull the curtain that surrounding at SPL III to prevent the test no be affected by outside light source. Select a type of illumination. They are D65, TL84 and “A”.
7、D65 is for general use and TL84 and A are mainly for metamerism measurement. Observer must dress dull gray cloth. The distance of observation from eyes to sample must be about 70 80cm with vertical direction to sample plate and master color. Rotate the table to 45, select illumination to D65 and eva
