Abstract
A single gloss sensor which can perform both DIN gloss measurement and DIN high gloss measurement, using the same hardware, and with minimal delay between the two measurements. The invention functions by directing light beams from a source to two different positions, either concurrently, or sequentially, between a position which measures gloss (75.degree.) and a position which measures high gloss (45.degree.).
