20090002407 | Inkjet Printing - A carrier for an array comprising a plurality of print heads, comprises an elongate bar having an ink conduit extending through the bar in a longitudinal direction. The carrier also comprises a print head receiving area adapted to receive or mount the plurality of print heads, and a heat transfer fluid conduit extending through the bar in a longitudinal direction. The carrier is arranged so that each print head received or mounted in the print head receiving area is in fluid communication with the ink conduit, wherein the heat transfer fluid conduit is disposed adjacent both the ink conduit and the print head receiving area. The carrier may comprise two ink conduits and two heat transfer fluid conduits. Heat transfer fluid may in use be conducted along the first and second heat transfer conduits in opposite directions. | 01-01-2009 |
20100225940 | DEVICE AND METHOD FOR PRINTING WITH CURABLE INK - A method for printing with curable ink is presented. The method comprises the steps of: generating an image wise pattern of spaced apart ink droplet locations for representing the image; and separating the pattern into at least first and second different interleaved portions, each portion comprising a plurality of droplet locations and the droplet locations of each interleaved portion being spaced apart from each other and spaced apart from the droplet locations of the remaining interleaved portions. In a first printing pass, ink droplets are deposited on the substrate at the drop locations of the first interleaved portion. Then, in a final printing pass, ink droplets are deposited on the substrate at the droplet locations of the second interleaved portion. The deposited ink droplets are then cured by exposing the deposited ink droplets to curing radiation in a first partial curing step between first and final printing passes and in a final curing step. | 09-09-2010 |
20130182021 | PRINTING - According to one example of the present invention, there is provided an image processor for generating data to control an inkjet printing system. The image processor comprises an image analyzer to identify within an image to be printed an area of substantially solid color and to define within the identified area a frame portion and an intra-frame portion, and a printer control data generator to generate printing system control data to cause a printing system to print a frame portion and an intra-frame portion of the identified area. | 07-18-2013 |
20140015903 | INK DELIVERY SYSTEM - An apparatus includes a tank for holding a fluid for delivery to a printhead, the tank being open to the atmosphere. A manifold enables the fluid to flow from the tank to the printhead, a height of the manifold being lower than a level of the fluid in the tank when the fluid is flowing from the tank to the printhead. A siphon has a lower end of the siphon that is connectable to the manifold. An upper end of the siphon extends above the level of the fluid and is openable to the atmosphere. A height of a segment of the siphon between the upper end and the lower end is lower than the height of the manifold. | 01-16-2014 |
20140063093 | PRINTING SYSTEM AND METHOD - According to one example there is provided a method of printing an image on a substrate using a printing system having a printhead. The method comprises forming, using ink from the printing system, a spittoon on the substrate, printing the image on the substrate, and whilst printing the image, ejecting ink from a printhead into the formed spittoon during a printhead maintenance operation | 03-06-2014 |
20140118429 | INK DELIVERY SYSTEM - An ink delivery device, method and non-transitory computer readable medium, the device may include a first closed pathway for a first ink flow through a multi-nozzle printhead in a first direction, and a second closed pathway for a second ink flow through the multi-nozzle printhead, the second pathway configured to move the second ink flow in a second direction. The device may further include a first shunt between the first closed pathway and the second closed pathway at a first end of the multi-nozzle printhead, the first shunt allowing some of the first ink flow to merge with the second ink flow, and a second shunt between the first closed pathway and the second closed pathway at a second end of the multi-nozzle printhead, the second shunt allowing some of the second ink flow to merge with the first ink flow. | 05-01-2014 |
20140253654 | METHOD AND APPARATUS FOR INK CURING - According to one example there is provided apparatus for curing ink on a substrate. The apparatus comprises a substrate support, a curing sheet positionable above the substrate support to create a gap between a substrate on the substrate support and the curing sheet. The apparatus further comprises an oxygen-depletion mechanism for reducing the oxygen level in the gap and an ultra-violet, UV, radiation source to apply UV radiation through the curing sheet to a substrate on the substrate support. | 09-11-2014 |
20140375732 | Fin Members to Guide Fluid - A fluid applicator mounting device includes a main body to removeably receive a fluid applicator module. The main body includes a common fluid channel having a main input port, a main output port, a supplemental input port to provide fluid to the fluid applicator module, and a supplemental output port to output fluid from the fluid applicator module. The fluid applicator mounting device also includes an input fm member disposed inside the common fluid channel and arranged proximate to the supplemental input port to guide fluid to the fluid applicator module. The fluid applicator mounting device also includes an output fin member disposed inside the common fluid channel and arranged proximate to the supplemental output port to guide fluid from the fluid applicator module away from the supplemental output port. | 12-25-2014 |
