Abstract

A method and apparatus for improving the quality of an image that has been developed by a liquid carrier is disclosed. Generally speaking, the invention is a blotter roll which includes an absorbing layer wrapped around a non-permeable rigid core. A vacuum system communicates with the exterior surface of the blotter roll to remove the excess fluid from the blotter roll and transport it out of the printing system.
