PURPOSE:To prevent the printing dirt by adding a radical polymerizational inhibitor in desensitizing solution and then effecting post treatment (post exposure and post heat) after the plate making of lithography. CONSTITUTION:A) 0.1-20wt% of hydrophilic coloid substance like cellulose derivative and alginate, preferrably 0.4-15wt%, B) 0.001-20% of radical polymerization inhibitor like hydroquinone, diphenylamine, dinitrobenzene, etc., preferrably 0.5-5%, C) desensitizing solution consisting in 40-90% of water.
