Note on the use of an Automatic Recording Densitometer

C. M. Tuttle, M. E. Russell

A recording physical densitometer designed to read strips from the type IIb sensitometer has been previously described.1 This instrument has been in service in the sensitometric department of the Kodak Research Laboratories for about one year, during which time it has been operated steadily. Approximately 100,000 sensitometric strips have been read thus far. The instrument is capable of an output of about 700 strips per day. — Experience has shown that more repeatable results are attained with this instrument than by routine, visual methods. Comparative data accumulated in an experiment lasting several weeks are presented, together with a time study of the two methods of densitometry. Certain features to be changed in the design of a new instrument will be discussed. The new instrument will be improved in both ruggedness and speed. — The advisability of using devices of this nature in a release print laboratory will depend upon a number of factors, such as initial cost, quantity and quality of output, and ease of maintenance.
