Abstract

In electrostatic master proofers, liquid ink images can be fused to a sheet in a more leisurely fashion than is normally encountered in copier applications due to the transfer of multiple images to the sheet and the corresponding large interdocument times. Under these circumstances, the opportunity exists for long dwell times to be used in the fusing/drying process. Some paper sheets, when soaked with an Isopar will bubble when the rate of Isopar removal is high. A high rate of Isopar removal is typically experienced in high temperature/short dwell time fusers. A suitable fuser, which does not cause Isopar bubbles, includes a slow moving plate or belt which provides a long dwell time, e.g. on the order of 1 minute. The fuser temperature is greater than the melt point of the toner, but lower than the boiling point of the Isopar.
