No-Mark Products has expanded its PressBoss Anti-Track jacket line to include the Heidelberg Quickmaster press. The PressBoss jacket replaces the net material commonly used on the delivery cylinder. Its surface is Diamond grade "?No-Mark' SiliCLEAN, and can last up to 12 months or more before change-out, depending upon care. It is pre-packed to OEM specifications with a cellular foam backing that helps prevent damage from severe paper jams. PressBoss jackets are available for all Heidelberg press models. The company also has a SiliCLEAN conditioner/cleaner available that helps ensure peak performance with its SiliCLEAN Anti-track products.
