Abstract:
An imaging device includes a substantially continuous web of media, and a web transport system configured to transport the continuous web along a web path. A print station is positioned along the web path and is configured to apply ink to the continuous web. A temperature leveling ink spreader is disposed along the web path downstream from the print station. The temperature leveling ink spreader includes a leveler roller including a heater configured to generate thermal energy to heat the leveler roller to a spreading temperature. The leveler roller is positioned to be partially wrapped by the continuous web to generate a predetermined dwell time between the continuous web and the leveler roller as the continuous web is being transported to equalize the temperatures of the web and ink on the web to within a predetermined range about the spreading temperature. The temperature leveling ink spreader includes a pressure roller positioned adjacent the leveler roller to form a spreading nip therebetween through which the continuous web is fed after the predetermined dwell time. The spreading nip is configured to apply a predetermined pressure to the continuous web and the ink thereon.
