Abstract
A color measurement network message log structure is disclosed for use in controlling communications among systems such as a plurality of film processing laboratories and remotely located systems, including a remotely located host system. Each processing laboratory includes at least one film processing apparatus interconnected to a densitometer for obtaining data related to color quality during film processing procedures. Signals representative of color quality data are transmitted from the densitometer to the host system through conventional modem devices and telecommunication lines. The host system can comprise a conventional processor and interconnected printer device. The processor is responsive to signals received from the densitometer at each processing laboratory to process the color quality data represented thereby. Each of the densitometers is provided with a dual port structure for communications with the film processing apparatus and remotely located system. Signals representative of data from the film processing apparatus can be accepted by the densitometer, with the densitometer including a network message structure for queueing the data represented by the signals for …
