(54) | Method and apparatus for producing planographic printing plate precursors |
(57) A method and an apparatus for producing planographic printing plate precursors. In
a production line for planographic printing plate precursors, a first applying device
(14), a first drying device (22), a second applying device (16), a second drying device
(24), a third applying device (18) and a third drying device (26) are sequentially
disposed along a direction of an aluminum web (12), which is a support for the planographic
printing plate precursors, is conveyed. Curl of the aluminum web (12) is adjusted
by each of the applying devices (14,16,18). Since the curl adjustment for the aluminum
web (12) is conducted simultaneously with or before applying a photosensitive material
onto the aluminum web, the coating film is not damaged and fogging is not caused. |
