The invention relates to an improved system for inkjet printing which results in images with increased permanence as measured by transfer of color from the image when the image is subjected to mechanical and/or chemical abrasion. The invention provides a fusible material that may be combined with any or all of the color inks used to create the image, or it may be used as a colorless fluid applied pre- or post-printing. The permanence of images produced by the system are comparable to those produced by electrophotography. The invention also relates to a printing apparatus that contains a means for fusing the image using heat applied after the printed substrate is ejected from the printer.
