1. Judgement of plastic surfaces in respect of gloss

The judgement of plastic surfaces with regard to gloss properties cannot be defined as a purely physical recognisable level. Subjective perceptions, both physiological and psychological, have a considerable influence on judgement.
A reflection meter value can, with due regard to certain conditions, interpret reflection properties which an observer perceives.
