Abstract:
An inverse mask image generating printer and printer module are provided. In one aspect, an inverse mask image generating module has an input adapted to receive the image data for an image to be printed said image data having color data for a first set of colors used in a first color model; an inverse mask image processor generating an inverse mask image using color data for one of the first set of colors; and an output providing the inverse mask image for use by a print engine. The inverse mask image is generated based upon the color data for a selected one of the first set of colors so that the inverse mask image can be generated without first determining color separation toner images that define amounts of color toner to be applied to form the elements of the image.
Abstract:
A system and method using an electrographic printer for printing of a print including an image and a particular pattern using techniques that also allows the selective application of non-conventional toners to an image formed on a printed media using registration marks to locate the original image on the printed media in order to provide proper alignment of the non-conventional toner image to the original printed image. The system employs two printers, the first is a conventional EP printer with the capability (internal or via driver software) to place registration marks on the print media along with the printed image, and a second printer adapted to read the registration marks on the printed media. Once the registration marks are read the non-conventional toner image is applied by the second printer in relative relation the positions of the read registration marks.
Abstract:
A method of printing a fluorescent image superimposed on a color image. An image source captures an image and converts the image to an image file that is transferred to a controller. The controller controls operation of a print head that prints a plurality of monochrome images forming a color image when the monochrome images are superimposed in registration one upon the other. In the case of a thermal dye printer, the plurality of monochrome images are formed by selective thermal transfer of dye from yellow, magenta and cyan dye color patches to a receiver. In the case of an inkjet printer, the plurality of monochrome images are formed by selective activation of ink channels containing cyan, magenta and yellow ink so as to eject cyan, magenta and yellow ink droplets onto the receiver. In the case of the thermal dye printer, the invention provides a dye carrier containing a phosphorous dye color patch. In the case of an inkjet printer, the invention provides that at least one of the channels contains a phosphorous colorant. After the color image is formed, using either the thermal dye printer or the ink jet printer, image information defined only by a selected one of the monochrome images is used by the print head to print a fluorescent image superimposed on the color image. The fluorescent image is printed bi-modally in registration with the selected one of the monochrome images. In this manner, the fluorescent image defines an outline of the color image, so that the color image is recognizable in a dark viewing area.
Abstract:
A printer and method adapted to precisely position a dye receiver portion. The printer and method properly positions the dye receiver portion for printing successive images onto the dye receiver portion with precise color registration and constant length, as the dye receiver portion unwinds from a roll of dye receiver. The printer comprises a print head for successively printing the images on the dye receiver and includes a rotator engaging the dye receiver roll for rotating the dye receiver roll by a plurality of incremental steps, so that the dye receiver is unwound from the dye receiver roll. The printer also includes a computer connected to the dye receiver roll for computing the incremental steps by which to rotate the dye receiver roll. The computer computes the incremental steps as a function of change of diameter of the dye receiver roll as each image of constant predetermined length is successively printed.
Abstract:
Printer adapted to guide a dye donor therein and method therefor. The dye donor ribbon has a leading end portion, which in turn has a plurality of sprocket holes spaced along parallel side portions of the leading end portion. A print head activates the dye donor ribbon to transfer dye therefrom onto a receiver for forming an image on the receiver. A dye donor ribbon take-up spool is disposed near the print head for taking-up the dye donor ribbon as the print head activates the dye donor ribbon. The take-up spool has a plurality of sprockets therearound sized to engage the sprocket holes in the leading end portion. A dye donor ribbon supply spool is spaced-apart from the take-up spool for supplying the dye donor ribbon therefrom as the print head activates the dye donor ribbon. A pair of spaced-apart oppositely disposed parallel guide rails extend between the take-up pool and the supply spool. Each of the rails defines a passage for guiding the dye donor ribbon along the passages. A support roller is disposed adjacently opposite the print head for supporting the receiver on the support roller in engagement with the dye donor ribbon as the print head activates the dye donor ribbon.
Abstract:
A bound document has front, back, and interior sheets with spine edges. The document has a binding strip and fasteners binding the sheets and the binding strip together. The strip has a flexible substrate with a face-attachment portion through which the fasteners are driven, and a wraparound portion that is bent so adhesive on the wraparound portion contacts the back sheet farther from the spine edge of the book than the feet of the fasteners. The strip also has a first spacer affixed to the interior surface opposite the face-attachment portion so that a fastener area is defined, the spacer at least as thick as the protrusion of the heads of the fasteners above the face-attachment portion.
Abstract:
Methods for generating an inverse mask image are provided. In one aspect, image data is determined for an image to be printed said image data having color data for a first set of colors used in a first color model; and, an inverse mask toner image is generated using color data for one of the first set of colors. The inverse mask image is generated based upon the color data for a selected one of the first set of colors so that the inverse mask pattern can be generated without first determining of color separation toner images that define amounts of color toner to be applied to a receiver to form the image.
Abstract:
Cross-track banding artifacts and wear in an electrophotographic (EP) print engine are reduced. A development member and a supply member are disposed so that charge is transferred between them in a charge-transfer region. The members are retained in a first position with respect to each other for a first dwell time, and neither member is rotated during the first dwell time, so that charge is transferred between members in the charge-transfer region. One of the members is rotated so that at least one point on one of the members is moved out of the charge-transfer region. The members are retained in a second position with respect to each other for a second dwell time that is greater than the time for one revolution of the development member, wherein neither member is rotated during the second dwell time.

Abstract:
A method of operating an electronic imaging system (20) as a distributed processor network is provided for a system that includes multiple imaging components such as digital cameras (22), printers (34), etc., wherein each component is connected to an intelligence module (24-36) having a microcontroller (58) and memory (62). In the method, the intelligence modules (24-36) are interconnected by way of a data interface (28-37) to form a system network. Next, different image processing steps are assigned to different ones of the intelligence modules (24-36). Image data entered and stored within the imaging system (20) is divided into a plurality of data groups, each of which preferably corresponds to a portion of an image. Finally, the data groups are serially entered through each of the intelligence modules (24-36) such that a specific sequence of image processing steps are conducted on each data group until the processing of a specific image is completed. The method efficiently utilizes all the microcontroller capability present in the network intelligence modules (24-36), thereby minimizing the processing time required to render images.
