The three step in the management of printing color

Color management theory will be the implementation of color management is divided into three steps: calibration, device characterization, color conversion. Calibration refers to the printing production process in each device for correction, normalization process parameters, make it work in stable state; device characterization refers to the premise to calibrate the equipment, the color characteristic file various hardware and software tools to measure the color data and generating device, recording device gamut characteristics, general color characteristic file has three kinds, namely the input profile equipment, display device and the output device. The third step is to use the color management module through the device independent color space (Lab) are device dependent color space (CMYK, RGB) conversion, from pre press to print the entire process consistency of color output. In the three step, the calibration and equipment characteristics is the key to effective implementation of color management. Calibration of the device is not only simple correction, but the diagnosis of a comprehensive production and process printing, printing production process parameter of the normalization and standardization. Device characteristic is the key to get high quality color characteristic file, focus on printing proofs can correctly reflect the selection of printing conditions, the use of measuring tools and professional color characteristic professional description file generation software.
