Abstract
Previously, attempts were made to modify black-and-white densitometers to make them suitable for color measurements, but considerable difficulty was experienced with such modifications. Therefore, the Ansco Laboratories developed new electronic circuits utilizing the full capabilities of the photomultiplier tube for this purpose. These developments, combined with other refinements, have made it possible to design a densitometer capable of using sharp-cutting filters to measure color densities up to 4.0 and over.
