摘要： Apparatus, methods, and systems for a vacuum conveyor for inkjet printing with adjustment to the covered area are disclosed. In some embodiments, a controller of a vacuum conveyor expands first one or more actuators of multiple first actuators of a substrate transportation system to decrease a suction width of an area of suction provided by the vacuum conveyor in accordance with a substrate width of a substrate being inkjet printed using the vacuum conveyor. A second one or more actuators of the multiple first actuators being retracted. The controller retracts multiple second actuators of the vacuum conveyor to increase the suction length of the area of suction while the substrate transportation system moves the substrate along the vacuum conveyor for inkjet printing of the substrate. The controller expands the retracted actuators of the multiple first actuators to increase the suction length as the substrates exit the vacuum conveyor.

摘要： The present embodiments relate to a printing apparatus capable of mitigating/preventing instances of turbulent deviation of ink jetted from print heads when printing onto a substrate, a severe form of which looks like woodgrain. The printing apparatus can include a jet plate disposed on a subjacent surface of the printing apparatus that can include a series of apertures formed in the jet plate that are configured to receive corresponding print heads of the printing apparatus. The jet plate can also include a set of wings extending from a first end of a central portion of the jet plate. The set of wings can form a cutout portion of the jet plate that can modify a direction and/or velocity of a flow of air from the cutout portion along the printing area to mitigate/prevent a woodgrain defect occurring when distributing a material onto the substrate.

摘要： A printing system includes a driving belt configured to drive media through the printing system relative to one or more print heads and a vacuum conveyor system. The vacuum conveyor system includes a vacuum chamber cover having a first surface and a second surface opposite the first surface, as well as a plurality of openings through the cover from the first surface to the second surface. A number of seals are disposed to match the location of openings. Each seal extends along the length of the vacuum chamber cover and is drivable to open or close a region with openings. A vacuum chamber below the second surface of the vacuum chamber cover is configured to apply a vacuum to the media through one or more of the openings that are open. The applied vacuum constrains the media on the driving belt by flattening it against the driving belt.

摘要： Methods, apparatus and systems for printing an image using an array of nozzles are described. In one example aspect, a printer system includes an array of nozzles and a control device coupled to the array of nozzles. The control device is configured to determine a step size for printing a current section of an image based on a set of masks. The set of masks includes one or more masks used for printing previous sections of the image. The control device is also configured to adjust the set of masks based on a printing mode to be used for the current section of the image. The array of nozzles is configured to print the current section of the image using a combination of the adjusted set of masks.

摘要： The systems and methods presented here completely separate a non-user pattern from the user jobs being printed. In fact, depending on the number of images in the job and the number of patterns provided by the manufacturer or press operator, the patterns may appear on different images of the job each time the job is printed. This is because the image marks are generated and processed according to the configuration of ROUS, independent of the user jobs being printed.

摘要： Disclosed are methods that couple effective nesting of fabric, as part of a textile cutting process, in which designs and/or graphic elements are directly printed on the nested elements, instead of on the entire textile sheet. Embodiments of the invention can address issues of waste and redundant printing, such as by starting with a blank textile roll, and printing only in the geometry areas of the patterns. Embodiments of the invention can increase fabric yield, because there are no constraints between the pattern geometries and the textile sheet print.

摘要： Mechanisms for adjusting the position of one or more print heads at an extremely fine resolution (e.g., less than 10 μm) are described herein. The adjustment mechanisms include a differential screw and an indexing wheel through which the differential screw extends. One threaded segment of the differential screw is connected to a threaded feature of a flexible body that is coupled to the print head(s), while another threaded segment of the differential screw is connected to a threaded feature of a rigid body that is coupled to a printer assembly. As the indexing wheel and differential screw rotate, the space between the flexible body and the rigid body changes based on the difference between the pitches of the threaded segments. The adjustment mechanisms described herein utilize the accurate, consistent motion of the flexible body upon experiencing pressure to effect predictable changes in the position of the print head(s).

摘要： Techniques for more accurately and efficiently replicating the alignment of one or more printer components with respect to another printer component are described herein. Replication may be achieved by using a fixture and a connection media to create a near exact replica of features of the fixture, or to temporarily hold multiple printer components in position while a joining layer of the connection media hardens. More specifically, a connection media, such as epoxy, can be used to fill an intentionally-established gap between connecting bodies or components that are held in a predetermined position by the replication fixture. The replication fixture represents a mechanical mounting interface that influences the position of a print head (or an array of print heads) within a printer housing or printing mechanism. Joining printer components in such a manner enables a stable mechanical coupling to be formed that does not require post operations.
摘要翻译：这里描述了用于更精确和有效地复制一个或多个打印机部件相对于另一打印机部件的对准的技术。复制可以通过使用固定装置和连接介质来实现固定装置的特征的接近精确的复制，或者在连接介质的连接层变硬时暂时将多个打印机部件保持在适当位置来实现。更具体地说，诸如环氧树脂的连接介质可用于填充由复制夹具保持在预定位置的连接体或部件之间的有意建立的间隙。复制夹具表示机械安装界面，其影响打印机外壳或打印机构内的打印头（或打印头阵列）的位置。以这种方式连接打印机组件可以形成稳定的机械连接，而不需要后期操作。

摘要： A radiation-curable ink composition for application to glass, ceramic, or metal by an inkjet printer. The ink composition can be applied to a glass, ceramic, or metal substrate to decorate, protect, etc. the substrate. In some embodiments, the ink composition includes a glass frits component, a chromophore component, and a UV-curable component. The glass frits component facilitates the fusing of the ink component with a glass, ceramic, or metal substrate to which the ink composition is applied. The chromophore component is the primary colorant of the ink composition. The UV-curable component facilitates activation of polymerization upon exposure to ultra-violet (UV) radiation, which causes the ink composition to cure and fix/pin to the underlying substrate. After the ink composition is applied to a substrate and cured by exposure to UV radiation, the substrate is heated to a temperature that causes the ink composition to fuse with the substrate.
摘要翻译：通过喷墨打印机施加到玻璃，陶瓷或金属上的可辐射固化油墨组合物。油墨组合物可以施加到玻璃，陶瓷或金属基材上以装饰，保护基材等。在一些实施方案中，油墨组合物包含玻璃料组分，发色团组分和紫外线固化组分。玻璃料组分有利于油墨组分与涂覆有油墨组合物的玻璃，陶瓷或金属基底的融合。发色团组分是油墨组合物的主要着色剂。 UV-可固化组分有助于在暴露于紫外（UV）辐射时激活聚合，这导致油墨组合物固化并固定/钉扎到下面的基底。在将油墨组合物施用于基材并通过暴露于UV辐射而固化后，将基材加热至使油墨组合物与基材熔合的温度。

摘要： Embodiments of the invention provide a technique that effects spot gloss or gloss control and/or variations on one image without requiring clear inks. This is preferably accomplished by use of a multilayer printing process in which an image is first printed using a first set of color print heads and then cured, and in which the image is again printed using a second set of color print head, but where the image remains uncured for a predetermined interval to allow the ink drops applied to the media to spread and thus introduce a gloss effect.
摘要翻译：本发明的实施例提供了一种在不需要清晰的油墨的情况下对一个图像产生斑点光泽或光泽控制和/或变化的技术。这优选通过使用多层印刷工艺来实现，其中首先使用第一组彩色打印头打印图像然后固化，并且其中使用第二组彩色打印头再次打印图像，但是其中图像保持未固化预定间隔，以允许施加到介质的墨滴扩散，从而引入光泽效果。
