  • Patent number: 9844953
    Abstract: In some examples, a first heating stage heats a print medium to a first temperature in a printing region when printing latex ink on the print medium, and a curing heating stage heats, in a curing zone, the print medium to a curing temperature greater than the first temperature to cure the latex ink on the print medium. A cooling stage located between the first and curing heating stages cools the print medium by directing a first part of airflow from the cooling stage to a printing zone, the cooling performed after the print medium has been heated by the first heating stage and prior to heating of the print medium by the curing heating stage. A second part of the airflow is directed from the cooling stage to the curing zone.

  • Patent number: 9381743
    Abstract: According to one example, there is provided a system for compensating for changes in printhead-to-printhead spacing in a printing system having multiple printheads mountable on a printhead support. The system includes a measurement system to determine a change in printhead-to-printhead spacing between different ones of mounted printheads, and a processor to determine compensation to be applied to the printing system to compensate for the determined change in printhead-to-printhead spacing.

  • Patent number: 9327523
    Abstract: A controller controls a first heating stage to heat a printing medium to a first temperature in a printing region when printing latex ink on the printing medium, and controls a second heating stage to heat the printing medium to a second temperature greater than the first temperature in a curing region to cure the latex ink on the medium. The controller controls a cooling stage located between the first and second heating stages to cool the printing medium after the printing medium has been heated by the first heating stage and prior to heating of the printing medium by the second heating stage.

  • Patent number: 9227436
    Abstract: A primer, a method, and a non-transitory computer-readable storage medium are described. An example non-transitory computer-readable storage medium stores instructions that, when executed by a processor, cause the processor to instruct a printer to advance a media by a first distance. The instructions, when executed, also cause the processor to instruct the printer to advance the media by a second distance different than the first distance to align the media with a cutter assembly. The instructions, when executed, also cause the processor to adapt an interleave mask based on the second distance. The instructions, when executed, also cause the processor to instruct the cutter assembly to separate a first portion of the media from a second portion of the media while the printer is printing on the media.

  • Patent number: 7084991
    Abstract: A printer is made by one firm; a RIP made/programmed by a separate RIP firm processes and sends to the printer image data; a two-bit data pipeline passes data through the RIP; a drop table converts data in the pipe to printer resolution. RIP firms set up the table with output dot-per-pixel structure different from the pipe. Ideally the table is in the printer but formed by the RIP; the RIP has precooked printmask instructions, and the printer, popup instructions to refine mask instructions; the instructions hide nozzle-out error and fix which pass prints each pixel; a computer, monitor etc. receive/create data and pass them to the RIP. Another aspect: a printer has a plural-bit data pipe, and interface to accept an external table to convert data from the pipe to numbers of dots per pixel. The interface best accepts a printmode recipe too.

  • Patent number: 7031021
    Abstract: While powerful in diffusion at one resolution to print photos at a finer resolution, the invention is not thus limited. It defines superpixels (“spels”) for each desired colorimetric level, generates/receives image data, renders by finding levels for image positions, and prints an image using selected spels. One invention aspect finds a randomized value at each found level and uses the value to select the spel from plural ones for each level. Another aspect derives/maintains a randomized-value matrix; and maps a matrix location to an image position, to select a random value at that location and spel for that position. Another uses the value in common for all planes to select a spel for each plane at the found level—compatible spels for different planes, to coordinate color placement in planes. Another controls defining/selecting for a blue-noise property of spels in aggregate. In another, spels defined for a level vary in value to yield nonintegral color quanta.

  • Patent number: 6915740
    Abstract: The printing apparatus comprises a printer and a laminator; media that advances and is printed in the printer is fed to the laminator device. The apparatus comprises means for loading in the laminator device the leading edge of the media leaving the printer, said loading means comprising a carrier, on which no printing is performed, attached to the leading edge of the media and to take-up means downstream of the laminator device, such that said carrier travels through the laminator device. Said carrier may comprise a length of lamination film, or a sheet or strips and means for their attachment to the media. The loading method comprises providing a carrier travelling through the laminator and attached to the leading edge of the media and to take-up means, and causing the carrier to advance leading the media through the laminator.

  • Patent number: 6860201
    Abstract: Media printed in a printer is fed in an integrated operation to a laminator to be at least partly laminated, the media between the printer and the laminator device forming a loose media buffer. Synchronization is provided between the advance of the media in the printer and in the laminator. This is done preferably using counting devices associated to the printer and the laminator, or buffer shape sensors, or control indicia on the media. The apparatus may perform a resetting operation of the media buffer.

  • Patent number: 6799823
    Abstract: One aspect of the invention lowers boundary artifacts by depleting selectively at a boundary, only in high-color-saturation areas. In another aspect, printmasking defines depletion regions. In yet another, a printer treats different drop-to-pass allocations as of opposite sign. Some preferred embodiments exploit the multilayer Shakes mask system: each mask represents a number of drops to fire, and masks are additive, depending on image content. In preferred embodiments the high-value mask is used in opposition, reducing the number of drops to fire. Bits are set in this mask at pixels close to boundaries, to define depletion regions that negate artifact-causing boundary coalescence. An adaptive version measures nonuniformity in an area-fill test pattern, and uses results to define localized depletion bits for high-value mask(s).

  • Publication number: 20040021879
    Abstract: A method to improve image quality in a printing device by storing in a memory of the printer at least a medium definition for a first medium, in a format which structures data about said first medium; and using the data contained in said medium definition when printing onto said first media. A downloadable media profile (210) for a first medium contains values for a plurality of parameters. A printing device comprises the downloaded media profile (210), firmware components (230) for managing the printing process, passing means (250), responsive to said firmware components (230), for passing data from said profile (210) to said firmware components (230) when printing on said first media.
