With the development of digital technology, high resolution scanner and digital camera are becoming more and more popular. Digital prepress technology is changing the traditional prepress process, such as color desktop publishing system, computer direct plate making system, digital proofing, digital printing, etc., from the image input device, the processing equipment to the final output devices are increasingly diverse.

Because of the color printing replication system is an open system, using the color space of different between different devices, the original colors tend to be between different device color space conversion, in order to make the manuscript from input to output, maintain the consistency of color, must be the introduction of color management. CMS(color mana). Gementsystem).

The meaning of color management.

Color is a visual characteristic that stimulates the human eye. Therefore, the quantitative description and control of color is an important and difficult task. In the case of color reproduction technology, color management is the application technology that correctly interprets and processes color information in the whole image reproduction process.

The task of color management is:

To solve the problem of data conversion in space, the best color matching between the devices is realized, so that the color of the image is the least distortion in the whole process.

The objectives of color management are:

In the whole process of printing of color transfer for precise control and management, really has nothing to do with the equipment used by color reproduction, meaning that the same color data, the output in any system, will obtain the ideal color copy.

The meaning of color management is:

The combination of color processing, control technology and corresponding software and hardware simplifies control and operation, so that inexperienced operators can finish color reproduction easily, accurately and quickly. The color management system can also reduce work time and material expenditure while completing production tasks. It allows operators to match colors on different input and output devices. Therefore, to obtain the printing effect of "what you see is what you get", you must use the color management system to control the whole printing process.
