An imaging drum has an outer surface configured for receiving an ink image from a print head and transferring the image at a transfer nip. The imaging drum has a central channel extending through the drum along a central longitudinal axis. An inner drum surface faces the channel and includes surface alterations that increase or decrease at least one of surface emissivities and heat absorption to mitigate thermal influences on the imaging drum and control temperature variability along the imaging drum. |
