Abstract
A method of coating well defined discrete areas of a flexible substrate by creating a lyophobic pattern on the surface of the web to leave a desired pattern of lyophilic areas. A layer of coating solution is laid down over the patterned web, the solution withdrawing from the lyophobic areas and collecting on the lyophilic areas.
