Abstract: A method for producing an electrically conductive thin film on a substrate is disclosed. Initially, a reducible metal compound and a reducing agent are dispersed in a liquid. The dispersion is then deposited on a substrate as a thin film. The thin film along with the substrate is subsequently exposed to a pulsed electromagnetic emission to chemically react with the reducible metal compound and the reducing agent such that the thin film becomes electrically conductive.

Abstract: An image forming apparatus includes a first toner image forming unit, a second toner image forming unit, and a transfer section. The first toner image forming unit forms a first toner image with use of a first toner. The first toner includes a binder resin. The binder resin has a weight-average molecular weight that falls within a range of from 12297 to 14019, both inclusive. The second toner image forming unit forms a second toner image with use of a second toner. The transfer section transfers the first toner image onto a print medium, and transfers the second toner image onto the print medium in a region that overlaps a portion or all of a region where the first toner image has been transferred. The print medium includes a polymer compound.
Abstract: A method of manufacturing an engraved plate used in intaglio printing, said plate being engraved by a tool, for example a laser beam, characterized in that the engraving tool uses data from a depth-map, based on a three-dimensional raster image of the document to be printed.

Abstract: A method for building microstructures, comprising the steps of forming a photopolymer mask on a substrate, having a mask thickness equal to or larger than a desired height of a microstructure to be formed; forming a latent image on the photopolymer mask by exposure to light; applying an electrical charge to the photopolymer mask; developing the cavities in the mask with a functional liquid toner material whose electrical charge polarity is the same as the charge on the mask; and solidifying the functional liquid toner material into a useful microstructure.
Abstract: An image forming apparatus includes an image holding member, a toner image forming unit, a color forming information applying unit, a transfer unit, a fixing unit and a color forming unit, the color forming information applying unit exposing a toner image formed on a surface of the image holding member from a back surface side of the image holding member, light transmitted through the image holding member applying color forming information to the toner image.
Abstract: An imprinting method is provided that, according to an embodiment, involves contacting an imprintable medium on a substrate with a template to define an imprint area in the medium, removing at least some of any imprintable medium present outside the imprint area, and separating the template from the medium.
