Abstract
An inkjet offset printer includes at least one printhead to eject ink on a release agent applied to an image receiving member for subsequent transfer of the ink to the surface of a recording media. The release agent is applied to the image receiving member by at least two release agent applicators. The release agent can be selectively applied to process sheets of recording media of different sizes to improve print quality. Selective application of release agent to the image receiving member prevents release agent from migrating to a transfix roll, and subsequently to the back side of the media which affects the image quality.
