Abstract: In an image forming apparatus that uses a stackless ADU and executes image formation on both sides of a paper sheet in a facedown mode, a CPU confirms, when double-side image formation is to be executed with two paper sheets, image formation on reverse surfaces of which is finished, being stayed in the ADU, whether monochromatic image formation or color image formation is to be executed on an obverse surface of a first paper sheet that is stayed in the ADU and has a reverse surface on which image formation is finished. When the color image formation is to be executed, the CPU controls the image formation on the obverse surface of the first paper sheet that is stayed in the ADU and has the reverse surface on which image formation is finished. When the monochromatic image formation is to be executed, the CPU controls the image formation on a reverse surface of a second paper sheet that is stayed in the ADU.

Abstract: Patterns of nanometer and micrometer dimensions are printed on a substrate by first forming a solution or suspension of a liquid and a printing material and then applying a layer of the solution or suspension to the substrate. Then, without applying pressure, a stamp provided with relief patterns is positioned at a distance of 0 nm to 500 ?m from the substrate with the relief patterns in contact with the layer of the solution or suspension. The liquid is then evaporated from the solution or suspension from between the substrate and the stamp so as to draw the suspension or solution by capillarity to the relief patterns and deposit the material on the substrate in accordance with the relief patterns of the stamp. Thereafter the stamp is separated from the substrate.

Abstract: The invention relates to a method for transferring a pattern from a stamping surface (31) of a stamp (30) to a receiving surface (21) of a substrate (20). The pattern is transferred to the receiving surface (21) by successively bringing portions of the pattern within such a range of the receiving surface (21) during a certain period, that the pattern is locally transferred from the stamping surface (31) to the receiving surface (21). The individual portions can be moved by means of individual actuators (50). By applying the method, the transfer of the pattern can be performed according to a wave, which is for example ring-shaped, moving from the center of the receiving surface (21) to the circumference, or linear, moving from side of the receiving surface (21) to an opposite side.
