1. Scope
1.1 This method is for measuring the specular gloss of paper at 75° (15° from the plane of paper). Although
its chief application is to coated papers (1), it is also used for a variety of uncoated papers.
1.2 This method is suitable for low- to high-gloss papers. For very high-gloss papers such as cast-coated,
lacquered, highly varnished (2-4) or waxed papers (5), and high-gloss ink films (6), TAPPI T 653 "Specular Gloss of
Paper and Paperboard at 20 Degrees" is preferred. T 480 has been shown to be suitable for gloss measurements of most
ink films on paper or paperboard. Differences in the color and diffuse reflectances of these ink films have a negligible
effect on measured gloss. For example, when white and black surfaces which are otherwise identical are tested, the white
surface will measure less than one gloss unit higher than the black.
1.3 This method does not measure image-reflecting quality.
