Abstract:
1. A method for manufacturing a lithographic printing plate, the method comprising: conveying a support, on which a photosensitive coating solution containing an organic solvent is coated such that a photosensitive coated layer is formed by the photosensitive coating solution; drying the photosensitive coated layer by a first heating means to a dry-to-touch state; heating the support and the photosensitive coated layer by a second heating means, which does not contact the support and the photosensitive coated layer, and which is provided at a downstream side of the first heating means, so that hardening of the photosensitive coated layer is promoted; and changing an amount of heat supplied by the second heating means while the support is being conveyed, wherein the amount of heat supplied by the second heating means is controlled in accordance with a thickness and a width of the support, such that a temperature of the photosensitive coated layer immediately after heating by the second heating means is a predetermined temperature which is set in accordance with the thickness and the width of the support.
