A compliant imaging surface for offset printing comprising a drum having an outer compliant elastomeric layer affixed to the drum, the outer compliant elastomeric layer being sufficiently compliant to contact ink pixels having at least first and second heights so as to fix the ink pixels to the final receiving medium. A second outer rigid layer is affixed to the outer compliant elastomeric layer and acts to keep pressure across a span of one pixel with the outer compliant elastomeric layer acting to allow deformation on the pixel to pixel span.

Compliant imaging surface for offset printing

A roller for applying pressure to a final receiving medium to transfer and fix an ink image thereon is provided. The roller includes a core surrounded by an inner elastomeric layer. A tubular elastomeric sleeve having a first, relatively high hardness surrounds the inner elastomeric layer. A thin outer compliant elastomeric layer is affixed to the outer surface of the sleeve and has a second hardness that is less than the first hardness of the sleeve. The outer compliant elastomeric layer of the roller has sufficient compliance to contact adjacent ink pixels having first and second heights and fix the ink pixels to the final receiving medium.
