Solve the color reproduction method:
The International Color Consortium (ICC) has proposed a color management solution based on ICC Profile, which is often referred to as ICC color management. The theory and principle of ICC color management are not described here. Only the methods and steps of applying ICC management are briefly introduced.
Through the ICC device profile, the colors in the image can be accurately mapped to the color gamut of the output device's color space to generate the same or very similar colors, thereby preserving the overall appearance of the original image. The more precisely the target profile describes the performance of the output device, the more accurately the color management system can convert the actual color values ​​in the image.
Creating a configuration file for the output device requires some auxiliary equipment, such as a spectrophotometer. With these aids and the following series of steps, a complete color correction profile can be generated. These steps can be divided into:
(1) Print color card - The pre-made color card is printed by the ink jet printer.
(2) Read the printed color card - The spectrophotometer reads the color card printed by the inkjet printer.
(3) Generate profile - Color profile for inkjet printer is generated by professional color correction software.
(4) Reprint the color card - Use the color-corrected profile to reprint the color card.
(5) Repeat the above process until the color is closest to the ideal color.
The closest ideal color is to expand the color space of the inkjet printer to the maximum extent. The ultimate goal of color correction is to approximate the colors actually printed on the inkjet printer and the colors seen on the screen. Since the inkjet printing machine is finished printing, the cloth blank needs to be steamed and washed, this process will also affect the color deviation, so the best method is to read the color data through the spectrophotometer after the color card of the post-processing. Make its data closer to the final product result.
