ABSTRACT:
Method and apparatus are described for setting liquid photographic materials which have been applied as a coating on a support web, while the coated web is moving substantially horizontally with the liquid materials on the underside of the web. Chilling of the liquid materials may be commenced while the web is moving upwards or downwards after coating, but any setting is not permitted to occur until the web has been turned to move substantially horizontally with the liquid materials on the underside. In this way, gravity and surface tension forces act in opposition to one another where the coating lies adjacent surface non-uniformities in the web and tend to retain the uniformity of coating thickness achieved at the time of coating.
