Color management workflow
The process of color management can be divided into four C: Calibration, Characterization, Conversion, and Check.
1 calibration. This is the basic condition for good color management. It refers to adjusting each device such as display, scanner, digital proofing machine and printing machine to the standard state to ensure that it meets or is accurate to the manufacturer's specifications and maintains certain stability. Make sure that the color of its performance is at or near the usual standard. Calibration is the basis of color management and the starting point of work. The purpose is to calibrate the device and let it run stably. The stability of the device is the basic condition for color management. Therefore, calibration is extremely important in the process of color management.
2 characterization. Refers to the input or output of standard color standards on the calibrated device, then measures these color standards, determines the color performance characteristics of the device based on the obtained data, and establishes a color profile (ICCProfile). The goal is to establish the color representation of the device or material and to mathematically record its characteristics for color conversion. Characterization is an important part of color management, and it is a prerequisite for color management.
3 conversion. Refers to the conversion of the color of an image or other object from the color space of one device to the color space of another device in order to obtain a visually consistent color.
4 check. That is, the inspection and evaluation of color matching between devices.
