Abstract: According to one example, there is provided a method of processing an image. The method comprises obtaining image data representing an image to be printed, determining, from the image data, pixel locations on a substrate where ink is intended to be deposited and pixel locations where no ink is intended to be deposited, and modifying the image data to define varnish to be deposited at at least some of those substrate pixel locations determined as where no ink is intended to be deposited.

Abstract: An image forming apparatus includes: a color toner supply unit configured to supply, to a recording medium, color toner for forming a toner image on the recording medium; a transparent toner supply unit configured to supply, to the recording medium, transparent toner having no releasability from a surface member bonded to a surface of the recording medium on which the toner image is formed; and a control unit configured to control the transparent toner supply unit to supply the transparent toner to cover the color toner supplied from the color toner supply unit to the recording medium.

Abstract: A user is prompted to select one coating mode from a plurality of coating modes having different methods of applying a transparent recording agent. If the selected coating mode is not available in a preset print setting, a print setting available in the selected coating mode is presented to the user, and the set print setting is changed.

Abstract: A method and system for printing documents with one or more embedded security features is provided. Security features are embedded in the document by co-printing magnetic and non-magnetic toner on a receiver before fixation by a fixing station. The combination of magnetic and non-magnetic toners in the image results in image elements that easily show alteration or are undetectable by visual means.

Abstract: In a method of producing a tiled print product, the print product is composed of a plurality of print substrates that are printed separately and are disposed adjacent to one another in at least one row. Each substrate is printed by means of a print process that creates a gloss gradient in a characteristic direction of production that is parallel to the row. The characteristic direction of production is inverted for every second substrate in the row.

Abstract: By using a high or low viscosity transparent toner, with respect to the other color toners, and different amounts of transparent toner lay-down, the gloss of an image printed by an electrophotographic device may be adjusted. By also applying the transparent toner as a negative mask, the differential gloss of the image may be reduced while still adjusting the gloss of certain portions of the image. Further, because different gloss levels may appear different at different viewing angles, transparent toner may be laid down to encode a transparent image within the image being printed. Such a transparent image may be useful as, for example, an authentication means for a document. Additionally, by varying the gloss levels on particular aspects of a printed image, multiple images of different gloss levels, which are prominent at different viewing angles can be made, thereby, a three-dimensional image effect can be achieved on the printed page.
