Editorial Bynchronisin is the relationship between the picture and sound film during the editorial processes.

Note: Through printing, one may produce a positive print from a negative film: a negative film from a positive film: or. if the reversal jirocess is employed, printing may be used to produce positives from positives or negatives from negatives. When the verb "to print'' is used, any of the above processes may be implied. 1.8.2 Projection Printing (Optical Printing).
