Key features of ColorWise

•Define whether RGB data is converted into the full gamut of the copier/printer or whether it is first converted into the gamut of another device, such as a press standard. This feature is helpful for making one device behave like another. It is also useful for evaluating the appearance of the RGB file under different printing conditions without having to reprocess the RGB data each time.

ColorWise color management (ColorWise) offers an open color architecture, allowing users to customize the GA-1121 to meet new printing needs as they arise. ColorWise supports ICC profiles, which are industry standard color profiles that describe the color behavior of a device. Downloading ICC profiles to the GA-1121 enables the GA-1121 to simulate a custom press (or another copier/printer), as well as accurately print colors from a particular monitor or a scanner. In addition, you can create customized ICC profiles for the copier/printer.

ColorWise also allows you to use any Status T densitometer by importing data in a standard file format (see Appendix B). In this case, it is important to note that the quality of the instrument used will determine the quality of the calibration.
