Abstract
A method of coating a photographic support with photographic material includes moving the support past a coating zone at a substantially constant velocity and generating a stream of equally sized and spaced drops of photographic coating liquid toward the coating zone so that the liquid is deposited at discrete, uniformly sized and spaced, sites of predetermined pitch.
Claims14
A method of coating a photographic support of the kind having a major surface of substantially uniform transverse dimension and a plurality of cell walls upstanding from said surface in a regular pattern to define a plurality of minute, open-topped, discrete cells, said method comprising:
- (a) moving said support through a coating zone in a direction orthogonal to said transverse dimension and at a substantially constant velocity;
- (b) generating at least one stream of equally sized and spaced drops of photographic coating liquid directed toward the coating zone;
- and
- (c) synchronizing the support movement and the rate of drop generation so that the drops of said stream are deposited in predetermined cells of said support.
