Abstract
There is disclosed a direct roll coating technique whereby a continuously revolving silk screen is interposed between the roll coating roll and the substrate to be coated. This silk screen serves to eliminate ridges which are usually formed when a direct roll coater is used. This technique is of special usefulness where ultraviolet curing of the coating on the substrate is contemplated.
