    • For short-run jobs, bright, saturated colors are often desirable. These are achieved by using the full range of colors available, referred to as the full gamut of the printer or, more simply, printer CMYK. See “Advanced Workflows” on page 2-7 for short-run printing examples.

  • Page 38: Rgb, Cmyk, And Pantone Colors

    (see Appendix B). The color data is converted when it is passed from one application to another or when the job is sent to the printer, so the processing occurs on your computer, as opposed to the Fiery 3850C.

  • Page 39: Simple Workflows

    Finally, by sending RGB files instead of larger CMYK files from applications to the Fiery 3850C, network traffic is minimized and jobs generally print faster. ColorWise uses ICC profiles to convert colors to the printer gamut or simulate other devices, such as an offset printing press. ColorWise manages color conversions for all users printing to the Fiery 3850C from Windows and Mac OS computers.

  • Page 54: Understanding Calibration

    3-2 Color Calibration Once you have calibrated the Fiery 3850C with ColorWise Pro Tools or with VisualCal, a calibration set is stored on the Fiery 3850C. This calibration set is used when it is associated with an output profile. Every output profile has an associated calibration set.

  • Page 55: How Calibration Works

    Measurements Measurement files contain numerical values that correspond to the toner density produced by the printer when it prints solid cyan, magenta, yellow, and black, and graduated tints of those colors. To create a measurement file, first print a page of color patches from ColorWise Pro Tools.

  • Page 56: Scheduling Calibration

    Since printed output from the printer is very sensitive to changes in temperature and humidity, the printer should not be installed near a window, in direct sunlight, or near a heater or air conditioner. Paper is sensitive to climate changes as well. It should be stored in a cool, dry, stable environment, and reams should remain sealed until they are needed.

  • Page 57: Checking Calibration Status

    Calibrating from the Control Panel using VisualCal VisualCal is a calibration method that allows you to calibrate your printer to a color output standard defined by the manufacturer. The calibration calculations performed by the controller software are based on a series of values entered on the control panel.
