  • Patent number: 5340495
    Abstract: Improved cleaner compositions and methods useful for removing ink from parts of a printing press are provided. The cleaner compositions comprise a fatty acid methyl ester and a nonionic surfactant which is an ethoxylated C.sub.4 -C.sub.10 alcohol. The cleaner compositions may further comprise a mixed heteric oxide of a higher chain alcohol, and water. The cleaner compositions, which are devoid of volatile organic compounds, eliminate the need to dry the parts of a printing press, particularly the rubber blanket, which need periodic cleanings during a run. The non-volatile cleaner compositions are combinable with printing ink compositions without appreciably affecting the printing characteristics of the ink. When printing is resumed while the rubber blanket is wetted with the cleaner, the cleaner becomes blended with the formed image as the image is received by the rubber blanket and the blended mixture is then printed.
