Metrology Standards - An Update

Over the past several years, there have been advancements and applications changes in the field of optical measurement metrology, specifically densitometry and spectrophotometry. Various standards have been modified or developed that establish the design specifications for these instruments allowing the graphic arts and photography industries to continue to enjoy a cohesive series of measurement instrumentation. Additional standards have been or are being developed to standardize new areas of importance such as the proper application of measurements for characterizing printing materials and system output as well as process control. This paper provides an update on the current status of activities in ISO TC 42 Photography and ISO TC 130 Graphic Technology reviewing standards in the field of measurement including documentary standards/revisions on instruments, spectrophotometry, densitometry and the application of these measurements in graphic arts.
