In 1922 L. A. Jones, [2] during his study of gloss of photographic papers using goniophotometry, developed a glossmeter based on his research, which provided closer correlation to gloss ratings assigned by visual evaluation. Jones's glossmeter used a geometric configuration of 45°/0°/45° whereby the surface was illuminated at 45° and two ...

Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its ...
