TAPPI T653 – Specular Gloss of Paper and Paperboard at 20 Degrees

Scope

1.1 This method is for the measurement of the specular gloss of high-gloss papers at 20 degrees (70 degrees from the plane of the paper).

1.2 This method is suitable for high-gloss coated, cast-coated, lacquered, highly varnished or waxed papers, and high-gloss ink films. For the measurement of low- to moderate-gloss coated and uncoated papers and low- to moderate-gloss ink films, TAPPI T 480 Specular Gloss of Paper and Paperboard at 75 Degrees is preferred. Neither method is a measure of image reflecting quality.

1.3 This method will provide different values for 20 degrees gloss than ASTM Standard D523 due to differences in optical geometry.
