Abstract: A semiautomatic analytical recording densitometer has been developed that illuminates the sample by means of a unique optical system. The light from the sample is then separated into its blue, green and red components. Each component is evaluated with a modified Macbeth Quantalog Photometer whose outputs, read by counters, represent integral densities. These outputs are fed into a coordinate converter that computes the equivalent neutral densities and these densities are recorded by a three-character printing unit on an X-Y flatbed recorder. The complete characteristic curves are plotted with the aid of a motor that moves the sensitometric strip to the next step after each has been measured. The outfit consists largely of commercially available components. It can be greatly simplified when only integral densities are required.
