ABSTRACT:
A composition for finishing, preserving and cleaning lithographic printing plates composed of a polyol having a molecular weight in the range of from about 50 to about 2,000; a maltodextrin obtained by the enzyme hydrolysis of corn or potato starch, a mixture of a C.sub.18 to C.sub.30 alcohol and an aminated, aliphatic C.sub.8 to C.sub.24 alcohol sulfate with a ratio of alcohol to sulfate ranging from about 1:1 to about 5:1; and a composition of hydrocarbons having a boiling point in the range of from about 175.degree. F. to about 500.degree. F., and a flash point of above about 100.degree. F., preferably containing 100% aliphatic components; and a substituted phenoxypoly(oxyethylene)ethanol having a hydrophile/lipophile balance of from about 8 to about 15; and a mono-, di- or tri-ethanolamine; and water; and an acid to impart a pH to the composition of from about 2.5 to about 6.5; and a buffer to maintain the pH, and preferably a bacteriostat/fungistat component.
