SUB-COMMITTEE ON PERFORATIONS [J. S. M. P. E.
LIBRARIES OF STOCK NEGATIVES
The problem of using stock negatives bearing the negative type of perforation is perhaps the most difficult to solve, particularly in such cases where it is necessary to intersperse such negatives with negatives bearing the proposed universal perforation. The problem to be faced by the industry would have to be faced regardless of the dimensions of the rectangular perforation ultimately adopted as universal, whether the height be 0.073 or 0.078 inch; and would be more serious with the former, which is the one recommended in this report. However, the advantages to be derived from adopting the 0.073-inch perforation in all other phases of motion picture work are so outstanding that it is believed that they justify taking means of adapting the existing stock negatives to a new perforation technic.
The proponents of the proposed perforation in 1931 pointed out the possibilities and suggested means of reperforating the stock negatives with the proposed universal perforation. The question of reperforating is rather serious, as at best it would be rather costly and some risk would be involved, particularly if the stock negatives to be reperforated are old and overshrunk. It is believed that the remarkable progress made recently in duplicating negatives offers the logical solution of the problem, and perhaps the most advisable. Duplicating stock negatives or using them for reprinting when the two types of perforation are not interspersed, could be done on a reserve printer the sprockets of which have not been altered to the new perforation. This machine could be retained during the transition period.
This analysis of the proposed universal perforation and its advantages are submitted to the Society and to the Standards Committee with the recommendation that the proposed perforation be adopted at as early a date as possible, so that new avenues may be opened for further advances in the technic of motion picture making in its many phases. Progress in the photographic, sound, and color fields will be hampered and retarded if the present dual standard is permitted to exist for any considerable length of time.

DISCUSSION
MR. SKINNER: It will be much easier to make a continuous sprocket for printing with this method because a flat side of an accurate part will be available,
