Abstract
The present invention provides a method and apparatus for cleaning printing press components with carbon dioxide snow or pellets. Upon impact, the snow or pellets dislodge debris adhering to the components and sublime to a non-hazardous gas. A typical component cleaned by the present invention would be a rotating blanket cylinder of an offset printing press. The snow or pellets are typically conveyed by an air stream under pressure to a moving nozzle, a series of fixed nozzles, or some other dispensing device.
