Abstract: This method to allow the use of low VOC (volatile organic compounds) solvents in blanket cleaning operations and the resultant product that is produced by this method involves the retrofitting of currently existing seals on printing press so that operators can use low VOC solvents in place of high VOC solvents. High VOC solvents are harmful to the atmosphere and humans alike. As VOC are lighter than the surrounding air, humans are subjected to inhalation of these harmful vapors which cause respiratory and other health ailments. The VOC continue to rise, mixing with nitrogen oxides, until they reach the troposphere forming thick layers of ozone or smog. The current movement of municipalities to limit the use of high VOC solvents have lead printers and others to use low VOC solvents which are inherently less evaporative than high VOC solvents. This lack of evaporation causes problems with having to handle greater volumes of waste to handle and dispose properly.

The thin flange can include a feature such as an inward-facing mounting groove, a threaded mounting bore, and/or an electrical feed-through.
