Graphic technology. Process control. Certified reference material for opaque area calibration of transmission densitometers Ingestion-build-239834 What is ISO 28590 about1 Scope This International Standard defines requirements for a half tone certified reference material which may be used for the opaque area percentage calibration of transmission densitometers or colorimeters for use in the graphic arts. This International Standard is not applicable to the calibration of transmission densitometers in terms of ISO standard diffuse density. NOTE Test methods for determining the opaque area percentage are given in the
