Methods and system for managing color management resources
A color printing system includes a color management server and one or more printing devices. The color management server manages color printing resources among the printing devices. A test chart is printed at a printing device and used to capture calibration measurement data. Calibration settings are defined for the calibration measurement data. A tone reproduction curve (TRC) is generated based on the calibration measurement data and the calibration settings. The TRC is stored with the TRC settings and calibration measurement data to be used at a printing device. The TRC settings are edited and the TRC associated with the measurement data is updated or regenerated to reflect the edited settings. More than one TRC is updated with the new settings if it uses the measurement data.
