    Introduction To take full advantage of your printer’s high resolution and make your images look their best, it is important that you understand levels of gray, line screens, scanner resolutions, scanned image formats, and their uses within specific applications. This chapter explains these concepts and describes how to use them with XANTÉ’s Enhanced Screening Technology, NEIT, XANTÉ’s Halftone Calibration Technology, to achieve the best quality in output.

  • Page 4: Line Screens

    Use the following table as a guide to produce 256 levels of gray. LPI To Achieve 256 Levels of Gray Printer Resolution 1200 x 1200 dpi 600 x 600 dpi Line Screens The number of levels of gray you would like to achieve is one factor in determining the appropriate line screen to use.

  • Page 5: Halftone Scanning

    Halftone Scanning The halftone scanning resolution is usually lower than that of the output resolution. Black and white images generally should be scanned at a resolution of 2 times that of the line screen used, if printing at 100% size. Use the following formula to determine the optimum resolution.

  • Page 8: Negative Enhanced Imaging Technology

    Negative Enhanced Imaging Technology Traditionally laser printers were designed to print positive images. XANTÉ’s innovative, patent pending Negative Enhanced Imaging Technology (NEIT) is the first technology to address the problems typically associated with producing negative images on a laser printer. The patent pending technology can be purchased as an option for your printer.

  • Page 9: Gamma

    Enhanced Screening XANTÉ’s Enhanced Screening Technology increases the number of gray levels available for a line screen setting. The option can be set from the printer’s front panel or through the PPD. If you use the PPD, you can select the levels of gray and gamma settings simultaneously.

  • Page 10: Accurate Calibration Technology

    The maximum amount of RAM disk available is equal to the total RAM installed minus the amount of RAM required for standard printer operation (a minimum of 8 MB). For example, a printer with 64 MB of RAM has 56 MB (64 - 8 = 56) available. RAM disk can be enabled in 1 MB increments up to the maximum available amount.
