All Electronic Color Correction - A Progress Report.

The interchemical electro-mechanical equipment for automatic color correction has previously been described. Since RCA took over the project, active development work has been and still is in progress on an all-electronic model. While the basic method of correction is the same as that in the earlier model, the final equipment will offer increased speed, greater reliability, lower weight and much quieter operation. This paper is in the form of a progress report, since it will be some time before a commercial device is available. Work with commercial firms is continuing to demonstrate a high degree of automatic correction by use of the device and is also aiding in setting up standard procedures applicable to the several printing methods. This work has pointed up the fact that careful control in the preparation of four separations that are theoretically correct justifies the establishment of definite standards and rather rigid controls, so that full advantage may be taken of the available degree of correction provided by the equipment.
