Micrographics. Duplicating film, silver, diazo and vesicular. Specifications and measurement for visual density Ingestion-build-205840 co-authored with Neil PhelpsWhat is this standard about? This document specifies visual diffuse transmission densities for second generation silver gelatin and diazo microforms and projection densities for second generation vesicular microforms. It also specifies methods of measurement. It does not apply to duplicates of microforms of technical drawings and other drawing office documents.
