  • Patent number: 7852536
    Abstract: A method for avoiding objectionable moiré in a color image can include identifying a problematic excitation angle associated with a problematic excitation in a marking process or in the color image and selecting a set of at least two halftone screens for rendering at least two separations of the color image wherein the set of screens is selected to avoid including significant screen fundamental, harmonic and beat frequencies at angles closer than about 1 degree of the identified problematic excitation angle. Halftoning the color image according to the selected set of screens avoids objectionable moiré associated with the problematic excitation.

  • Patent number: 7850069
    Abstract: An operation support system includes a progress information providing unit, an entry device, and an updating unit. The progress information providing unit stores progress information indicating to which operation stage an operation procedure has progressed and provides the progress information in response to a request made from an external device. The entry device includes an entry tool and a reading device. The entry tool makes an entry into a paper form associated with the operation procedure. When an entry is made into an entry field of the paper form using the entry tool, the reading device reads identification information presented in the entry field. The updating unit updates the progress information, which is stored in the progress information providing unit, based on an operation stage associated with the identification information, which is read from the entry field by the reading device.

  • Patent number: 7850159
    Abstract: A method is provided for preparing one or more print jobs for finishing. The method includes dividing a portion of the one or more print jobs into a first set of pages corresponding with a first print output stack having one stack height and a second set of pages corresponding with a second print output stack having another stack height. A printing instruction is provided for causing at least one of the first and second sets of pages to be printed in a multiple up format when either one of the output stack heights is greater than a selected output stack height, or when the sum of the stack heights is greater than the selected output stack height. The printing instruction is used, pursuant to printing the first and second sets of pages with the printing instruction, for (1) causing the at least one of the first print output stack and the second print output stack to be printed in multiple-up format, and (2) preventing either one of the print output stack heights from exceeding the selected output height.
