Color Management In The Electronic Prepress Systems Research And Applications

The development of colorful desk print system is changing with each passing day, which brings us more beautiful information more quickly. Colorful duplication is the key task of plate making and print. For a long period of time the differences among original documents, shows, samples and print brings users great puzzle that the colors of printed pictures are totally different from those in screen or the colors of products are different from those of samples in signed contracts. Moreover, there are varies color machines such as scanner, digital camera, screen, printer, press, and the color distinguish functions of the machines in different types or even those in the same types but different models are not the same, which brings unnecessary disputes to sellers and customers. The above problem perplexes the print industry for many years and color management must be carried out if we want to settle the above problem.Color management is the core technique of desk print system. Through color management that what you see is what you get and that what you set is what you get. In the article we expound the principle and technique of color management and introduce with details that the realization steps of color management system and its structure application process through the realization of the color management to scanner, print and image-setter and combining with the fact production.The article is divided into 7 chapters.In chapter one we introduce the basic theory of printed colors, expounding the feeling, feature of colors and expression ways of mixed color system.In chapter two we narrate the constitution of DTP system. At present DTP system is used very broadly and developing very rapidly and in the chapter we introduce the development history and components of DTP system.In chapter three we expound with emphasis the color management of DTP system. The chapter is the key part of the article, introducing exhaustively the content of color management, the necessity of color correction, the transfer of color space, the means of color match and the process of color management system.In chapter four, chapter five and chapter six we introduce the means and steps of the color management system to the color correction ofscanner, printer and image-setter.In chapter seven we introduce the procedure constitution and flow chart of color management system.
