Abstract: A system and method for printing a predetermined image onto a substrate includes steps or structure for determining a first area on the substrate where a colorant is to be deposited; determining a second area which is immediately adjacent to the first area; depositing an image-enhancing precoat over the first area and the second area; and depositing a colorant on the exposed surface of the image-enhancing precoat substantially so as to be over the first area, whereby a border of precoat material will be defined about the printed image on the substrate. A second aspect of the disclosure involves sealing a printed image on a substrate by applying an aftercoat.

Abstract: A method of thermal transfer printing on a substrate includes the steps of determining, on a pixel by pixel basis, where colorant is to be located on the substrate; applying an image-enhancing precoat to each pixel where colorant is to be located, as well as to at least one immediately adjacent pixel; and depositing a colorant onto the precoated predetermined pixels. The precoating that is applied to the immediately adjacent pixels helps retain the precoating to the substrate, among other advantages. A second method, for printing on a rough substrate, includes steps of applying an image enhancing precoat so as to form bridges across valleys of said rough surface; and subsequently depositing a colorant onto the precoat. A third printing method includes the steps of applying a precoat to the substrate which has one or more voids defined therein; and depositing a colorant onto the precoat so as to bridge over the voids in the precoat. Related systems and printed products are also disclosed.

Abstract: A system and method for printing a predetermined image onto a substrate includes steps or structure for obtaining pixel data which renders a portion of the predetermined image and relates to whether a colorant is to be deposited in a predetermined area comprising at least one subject pixel and at least one adjacent pixel; determining whether a colorant is specified for any of the predetermined area; and depositing an image-enhancing coating over the subject pixel on the substrate if the above determining step determines that a colorant is so specified, whereby a portion of the image-enhancing coating receiving area is successively determined "on-the-fly" using a minimal physical memory space without sacrificing the system performance. A second aspect of the disclosure involves an efficient method and structure for converting a pixel data relating to the deposition of the image-enhancing coating material format into a compact data format which is acceptable by a printer.
