    • Fixing devices for fixing marking material to a substrate, printing apparatuses and methods of fixing marking material to a substrate are provided. An exemplary embodiment of the fixing devices includes a first roll including an outer surface; a second roll forming a fixing nip with the outer surface of the first roll at which is received a pre-heated substrate on which marking material is disposed; a release agent applicator system including a supply of a release agent having a viscosity of from about 10 cST to about 300 cST, and a release agent applicator for applying the release agent to the outer surface of the first roll; and a thermal energy source for heating the outer surface of the first roll to a temperature of less than a boiling point of the release agent. The first roll and second roll are operable to apply heat and a pressure of at least about 500 psi to the pre-heated substrate and marking material at the fixing nip to fix the marking material to the substrate.
    • 提供了用于将标记材料固定到基底上的固定装置,印刷装置和将标记材料固定到基底上的方法。 固定装置的示例性实施例包括:包括外表面的第一辊; 第二辊与所述第一辊的外表面形成定影辊隙,在所述第二辊上容纳预先加热的衬底,所述预热衬底上设置有标记材料; 包括提供粘度为约10cST至约300cST的脱模剂的脱模剂施用器系统和用于将脱模剂施加到第一辊的外表面的脱模剂施用器; 以及用于将第一辊的外表面加热到低于脱模剂沸点的温度的热能源。 第一辊和第二辊可操作以将热量和至少约500psi的压力施加到预热衬底和在定影辊隙处的标记材料,以将标记材料固定到衬底上。
