Abstract:
1. A method for producing a lithographic printing plate comprising: applying a first coating liquid having a composition comprising at least a sensitizing dye, a radical polymerization initiator, and a radical polymerizable compound onto a belt-like support continuously conveyed, and drying the applied first coating liquid to form an image recording layer; cooling a second coating liquid for an overcoat layer in a manner that the temperature, T applying the second coating liquid for the overcoat layer onto the image recording layer; cooling the belt-like support after forming the image recording layer and before applying the overcoat layer in a manner that the temperature of the belt-like support having the image recording layer formed thereon falls within the temperature range of the second coating liquid for the overcoat layer; initially drying the overcoat layer by blowing cold air parallel to a surface of the overcoat layer at an air velocity of 8 to 15 m/sec after applying the overcoat layer and before drying the overcoat layer, the cold air having a low temperature of not less than a lower limit in a temperature range of the cooled belt-like support and not more than the lower limit +30° C. and having a dew point of not more than 5° C.; and drying the overcoat layer after the initial drying.
