Abstract
In a method of producing a photosensitive planographic printing plate according to the present invention, a web is coated with a coating solution, and a coating solution film thus formed is rapidly dried. For this drying, fresh air is blown onto the web W heated with a heat roll such that the air is blown parallel to the coating solution film. The coating solution film can thereby be prevented from changing its thickness due to an air stream during drying, while the coating solution film can be rapidly dried. Accordingly, the coating solution film can be dried before the film is leveled, to form a coating layer having uniform thickness.
