Gloss

The luster or shininess of paints and coatings. Different types of gloss are frequently arbitrarily differentiated, such as sheen, distinctness-of-image gloss, etc. Trade practice recognizes the following gloss levels, in increasing order of gloss:flat (or matte)-- practically free from sheen, even when viewed from oblique angles (usually less than 15 on 60-degree meter); eggshell-- usually 20-35 on 60-degree meter; semi-gloss--usually 35-70 on 60-degree meter; full-gloss--smooth and almost mirror-like surface when viewed from all angles, usually above 70 on 60-degree meter.
