    • A calibration target that describes the expected behavior of the copier/printer is contained in each output profile. After you have calibrated the GA-1121, a calibration set is stored. This calibration set will be used when it is associated with an output profile. Every output profile has an associated calibration set.

How calibration works Success in obtaining satisfactory print quality from the GA-1121 depends on many factors.

  • Page 40: Scheduling Calibration

    1-15. Scheduling calibration In general, you should calibrate the GA-1121 at least once a day, depending on the volume of print jobs. If it is very important to maintain consistent color, or if the copier/printer is subject to wide fluctuations in temperature or humidity, calibrate every few hours.

  • Page 41: Checking Calibration Status

This action ensures that all your changes to Spot-On color definitions are stored on the GA-1121 and available for use when printing documents that contain spot colors.

  • Page 97: Color Setup

    Color Setup allows you to configure the default color management settings for the GA-1121. These settings are applied to all print jobs sent to the GA-1121, unless a user overrides them for an individual job by changing settings in the printer driver.
  • Page 98 3-32 ColorWise Pro Tools Once you have made your changes, you must click OK or Apply for the changes to take effect. Clicking OK sets the new defaults and closes the Color Setup window. Clicking Apply sets the new defaults and keeps the Color Setup window open. Clicking Cancel closes the Color Setup window without applying any changes to the default settings.

    For the best color accuracy, calibrate the X-Rite DTP41 spectrophotometer every time you calibrate the GA-1121. You can initiate the calibration sequence in ColorWise Pro Tools Calibrator as part of the process of GA-1121 calibration. The computer may also prompt you that it is necessary to calibrate the spectrophotometer.
