Paper and board. Measurement of specular gloss - 75 degree gloss with a converging beam, TAPPI method Ingestion-build-228203 An air entrainment device consists1 Scope This part of ISO 8254 specifies a method for measuring the specular gloss of paper at an angle of 75 to the normal to the paper surface. Although its chief application is to coated papers, it may also be used for glossy uncoated papers such as supercalendered papers. NOTE 1 This method does not provide an assessment of image reflecting quality and should not be used for cast coated, lacquered, highly varnished or waxed papers or for high gloss
