Abstract: Nanoimprint lithography forms a microfeature array on a substrate responsive to inkjet printing techniques for high resolution printing of circuit elements and other features with highly accurate fidelity to predetermined boundaries. The microfeature array is defined by micropillars formed between intersecting microchannels in the substrate. The micropillars are responsive to a sequence of ink droplets in a highly controlled and predictable manner based on the droplet volume, droplet spacing and temperature. The flow of liquid ink is restrained by the micropillars for pinning the ink for avoiding uncontrolled ink flow as occurs on a flat surface. Subsequent layers of deposited ink tend to follow pining of previous layers, allowing an iterative buildup of layers for forming a trace of sufficient thickness and a high aspect ratio allowing traces extending above the depth of the microchannels for aiding communication with surface mount components.

Abstract: The invention relates to a method of aligning a plurality of printed motifs on a sheet (3) in a converting machine (10). An actual position (Pa_1) at a first sensor is defined as an initial reference position (P_ref1) for the sheet, and at least one displacement error (Δd2) is calculated and compared to a first threshold (T1). If the displacement error is lower than the first threshold, then the angular position (α) of a printing cylinder (42) in the second flexographic printing unit (16b) is adjusted. However, if the error is higher than the first threshold, then at least part of the of the displacement error (Δd_2) is corrected by modifying the speed (V) of a vacuum transfer unit located between the first printing unit and the second printing unit.

Abstract: The present invention relates to a panel as well as a method for producing a panel, in particular a wall- ceiling- or floor panel. The method according to the invention provides that a layer of liquid radiation curing acrylate with a low Martens hardness is applied on a support layer in a first step. This is followed by an application of an intermediate layer in a second step and thereafter the application of a further layer wet-on-wet, which as a Martens hardness after curing which is larger than the Martens hardness of the first applied layer. The resulting panel has an intermediate layer with an inhomogeneous hardness profile due to the wet-on-wet application which leads to particularly advantageous properties.

Abstract: An image forming system includes an image forming apparatus and a sheet laminator. The image forming apparatus forms an image on a sheet being conveyed as an inner sheet. The sheet laminator performs a sheet laminating operation on a two-ply sheet in which the sheet conveyed from the image forming apparatus is inserted between two sheets of the two-ply sheet. The sheet laminator includes a heater and circuitry. The heater heats the two-ply sheet during the sheet laminating operation. The circuitry is to execute a control mode when a specific abnormal event occurs among a plurality of abnormal events that occurs in the image forming apparatus, where the control mode maintains heating by the heater of the sheet laminator for a predetermined time and interrupt the heating by the heater when an abnormal event other than the specific abnormal event occurs.

Abstract: Hot foil stamping machine stamping a foil onto a substrate, which improves stamping quality under changing conditions, includes a control unit for controlling the temperature of the stamping interface surface to a predefined desired temperature. The control unit receives at least an actual temperature of the heating plate from the at least one temperature sensor and provides a manipulated variable to the at least one heating device. Further, the stamping machine includes a state observer for estimating an actual temperature of the stamping interface surface of the at least one stamping plate based on a physics-based analytical model of the heat transfer between the heating plate and the stamping plate. The control unit also includes a feedback controller for calculating the manipulated variable for a heating device based on the predefined desired temperature and the estimated actual temperature of the stamping interface surface provided by the state observer.

Abstract: A sheet processing device has a moveable beam (36) that moves in the vertical direction, a gripper bar (30) for gripping a sheet that travels through the sheet processing device (10), and a gripper bar locking device (40) that can lock the gripper bar (30) in a precise position. The gripper bar locking device (40) has a locking lever (68) that is pivoting between a rest position and a locking position. The locking lever (68) is connected to a vertical linear guide coupled with the moveable beam (36) resulting in a precise, compact and simple system to lock the gripper bar.
