PURPOSE:To obtain a coating film which is stuck fast to printing areas and durable in printing by a method wherein form plate correction liquid for correcting a printing area to a nonimage area for waterless lithographic printing in which silicone rubber layer is used as an ink-repelling layer is made of silicone rubber solution containing specific ingredients. CONSTITUTION:Form plate correction liquid which corrects a printing area to a nonimage area for waterless lithographic printing in which a silicone rubber layer is used as an ink-repelling layer is made of silicone rubber solution which contains linear organopolysiloxane in 100 pts.wt. having each 3 alkoxyl groups on the opposite ends, titanic condensed catalyst in 0.1-5 pts.wt., and organic solvent in 100-5000 pts.wt. Such materials as tetrabutyl titanate, tetra 2- ethylhexyl titanate, triethanolamine titanate, and tetra isopropenyloxy titanate can be exemplified for use for the titanic condensed catalyst. Such materials as n-hexane, n-heptane, ethyl acetate, mineral spirit, toluene, and xylene can be cited as definite examples for use for the organic solvent. |
