摘要： Inkjet printing systems and methods dynamically control meniscus pressure at a nozzle to more reliably deliver ink to a substrate. The systems and methods include inferring an angle of a longitudinal axis of a printhead relative to the vertical reference axis based on an orientation signal from an orientation sensor, determining a target feed fluid pressure upstream of the nozzle and a target recirculation fluid pressure downstream of the nozzle, thereby to maintain a target pressure differentiation across the nozzle based, at least in part, on the inferred angle of the longitudinal axis, and controlling a variable feed pump speed and a variable recirculation pump speed to obtain the target feed fluid pressure and the target recirculation fluid pressure.

摘要： An object is to provide a liquid ejection head that is more reliable than conventional ones. The liquid ejection head includes a pitch conversion member. The pitch conversion member includes a plurality of first openings respectively connected to a plurality of first channels, and a plurality of second openings respectively connected to a plurality of second channels. A region where a plurality of the first openings are provided and a region where a plurality of the second openings are provided overlap as viewed from a penetration direction of the first openings and the second openings. A first distance in a second array direction between the two first openings closest to each other in the second array direction intersecting a first array direction is shorter than a second distance in the second array direction between the two second openings closest to each other in the second array direction.

摘要： A printing platform includes a printing engine with one or more printheads arranged such that the ink drops are jetted vertically upwards against the action of gravity; and a substrate transportation system where the normal to the surface in contact with the substrate is parallel and with opposite direction to the travelling direction of the jetted ink drops. It is necessary to counteract the weight of the substrate during the printing process to avoid it from falling under the action of gravity. This is achieved through any of a mechanical element that interferes with the falling of the substrate and that keeps it in place; or a system that generates adhesion forces between the element that transmits the motion to the substrate, typically a conveyor belt, and the substrate through the action of electrostatic forces, an air pressure differential between both faces of the substrate, or any other suitable mechanism.

摘要： Example implementations relate to random wave mask generation. Some examples may distribute data points in a mask area based on a probability density function. The probability density function may have a maximum probability density located at a first edge and a second edge of the mask area. Some examples may also identify a wave curve that fits the data points. The wave curve may include oscillating waveforms of varying amplitudes. Some examples may also generate a random wave mask based on the wave curve.

摘要： A method of printing an image using a printing system having first and second overlapping printhead segments. The method includes the steps of: (i) identifying a strip of the image to be printed in an overlap region of the first and second printhead segments; (ii) determining a continuous seam in the strip based on a cost function, the cost function including a parameter selected from the group consisting of: (a) minimizing a density of printed ink along the seam; and (b) maximizing a luminance along the seam; and (iii) printing the image using the first and second printhead segments, the printing including stitching the first and second printhead segments across the seam. The strip contains variable image content and the seam has a varying position within the strip.

摘要： A multi-color printer has an array of monochrome fixed inkjet printheads aligned in a media feed direction. The printer includes: a first printhead positioned furthest upstream relative to the media feed direction; a second printhead positioned furthest downstream relative to the media feed direction; and a third printhead positioned between the first and second printheads. Each printhead is supplied with a respective ink from a multi-color ink set, the first printhead being supplied with a lowest luminance ink of the ink set and the third printhead being supplied with a highest luminance ink of the ink set.
