摘要： Systems and techniques for improving ink jet ink durability and adhesion to a substrate. The techniques may include applying a varnish to the surface of the substrate, curing, in an initial curing step, the varnish with an ultraviolet (UV) lamp, and applying a pigmented ink to at least a portion of the substrate. The initial curing step may comprise pinning the varnish with the UV lamp in a low-power state. The techniques may additionally or alternatively include applying a layer of pigmented ink and varnish at substantially the same time, allowing the pigmented ink and varnish to at least partially mix, then pinning or curing the ink/varnish combination.

摘要： Techniques for operating a printer are provided. In an example, the printer can include a print head a cure light and a controller. The controller can be configured to move the print head relative to a print media to print a given image, to move the cure light relative to the print media at a cure speed in response to the cure light passing over a printed portion of the given image to cure the ink of the given image, and to move the cure light at an index speed in response to the cure light passing over a non-printed portion of the given image, wherein the index speed is greater than the cure speed.

摘要： Systems and techniques for preserving and improving ink jet nozzle health and printing reliability are disclosed herein. The method may include monitoring whether a triggering event has occurred. In response to detecting the triggering event has occurred, pumping at least a portion of ink contained in a header tank in a direction toward an ink cartridge through a tube connecting the header tank to the ink cartridge. The header tank connected to a print head included as a part of a scan head. The method may further include circulating the ink through the tube back into the header tank, and agitating the scan head by moving the scan head along an x-y gantry. Additional methods may include reverse purging, ejecting a portion of ink through nozzles on the print head while simultaneously wiping a nozzle plate included on the print head, and randomizing print head location when printing.

摘要： Embodiments of the invention are directed to a transfer lamination process and apparatus that reduces substrate warpage. In some embodiments, the transfer lamination process is performed using a transfer lamination device, which includes a transfer unit, a substrate rotator, and a transfer ribbon having a carrier layer and a transfer layer attached to the carrier layer. In some embodiments of the transfer lamination process, a transfer section of the transfer layer is transferred from the carrier layer to a first surface of a substrate using the transfer unit. In some embodiments of this transferring step, the transfer section is heated and pressed against the first surface of the substrate using the transfer unit, and the carrier layer is detached from the transfer section. The substrate is then inverted using the substrate rotator. At least a portion of a second surface of the substrate that is opposite the first surface is then heated using the transfer unit without transferring the transfer layer to the portion of the second surface.
