摘要： The present invention relates to an ink composition suitable for being ejected from an inkjet marking device at an operating temperature. The ink composition comprises stable dispersed colorant particles and stable dispersed latex resin particles, wherein the ion sensitivity of the colorant particles is larger than the ion sensitivity of the latex resin particles, the ion sensitivity of the colorant particles (ISc) being expressed according to equation 1, and the ion sensitivity of the latex resin particles (ISl) being expressed according to equation 2: ISc=Zcav(xcMNaCl)/Zcav(H2O) equation 1 ISl=Zlav(xlMNaCl)/Zlav(H2O) equation 2 The invention further relates to an ink set comprising such an ink composition and a primer composition comprising a precipitating agent, preferably a multivalent metal salt. The invention also relates to a method of printing using such an ink set. The inks and ink sets according to the present invention are capable of improving the transport robustness of prints, in particular of prints on machine coated media.

摘要： A print head includes a plurality of chip-like tiles arranged on a common substrate, each tile having a front face with an array of recording elements disposed in the front face in a predetermined pattern, and a generally rectangular contour with a cut-out formed at at least one of its four corners, each cut-out being delimited by two reference-defining walls extending normal to one another and to the front face and serving as a reference for positioning the tiles on the substrate so as to establish a predetermined positional relationship between the recording elements of the different tiles. The substrate has a plurality of recesses accommodating each at least a part of a tile and having side walls that define engagement surfaces for each of the reference-defining walls of each tile, the substrate is formed of a material that is suitable for photo-lithographic processing, and the engagement surfaces of the substrate are surfaces formed by photo-lithographic techniques.

摘要： A droplet ejection device has a nozzle head with a plurality of ejection units, each of which includes a nozzle, a duct connected to the nozzle, and an electromechanical transducer arranged to create a pressure wave in a liquid in the duct so as to expel a droplet of the liquid from the nozzle. The device further includes an electronic control circuit arranged to apply control signals to the transducers and to receive detection signals that are generated in the transducers in response to the transducer being exposed to pressure fluctuations. The nozzle head includes a reference duct which has an electromechanical transducer serving as a reference transducer. The control circuit is arranged to subtract a detection signal of the reference transducer from a detection signal of at least one of the ejection units.

摘要： A substrate plate is provided for at least one MEMS device to be mounted thereon. The MEMS device has a certain footprint on the substrate plate, and the substrate plate has a pattern of electrically conductive leads to be connected to electric components of the MEMS device. The pattern forms contact pads within the footprint of the MEMS device and includes at least one lead structure that extends on the substrate plate outside of the footprint of the MEMS device and connects a number of the contact pads to an extra contact pad. The lead structure is a shunt bar that interconnects a plurality of contact pads of the MEMS device and is arranged to be removed by means of a dicing cut separating the substrate plate into a plurality of chip-sized units. At least a major part of the extra contact pad is formed within the footprint of one of the MEMS devices.

摘要： The present invention provides a conveyor mechanism for conveying sheets. The conveyor mechanism comprises a movable conveyor body, a drive mechanism, and an adjustment system configured to detect and correct skewing of the conveyor body, comprising one or more markers provided on or in the conveyor body, a sensor arrangement for detecting each marker at two or more discrete positions, and a processor to determine the skewing of the conveyor body. The conveyor body and the drive mechanism of the conveyor mechanism are mounted on a movable conveyor frame, and the adjustment system includes a frame shifting device comprising one or one or more actuator for shifting or moving the conveyor frame relative to a fixed framework. The invention also provides a related method of correcting skewing in a conveyor mechanism for conveying sheets along a transport path.
