How to implement color management of Paper Gift Pack printing production in paper packaging enterprises?

(I) System composition

A complete color management system should include the characteristic files of input, display and output devices, the standard detection objects required by the production software of characteristic files and the creation of characteristic files, the color management model, the connection space of characteristic files and the interface of application software. At present, there are a variety of feature file making software on the market, such as Kodak, ColorFlow, ProfileEditor, MonacoProfiler software and so on. Standard detection objects include those required to obtain scanner, digital camera, display property file and output device property file.

Color management should have the standard light source, high quality color characteristics file generation software, advanced color management system, the standard of measuring instruments and testing tools, the color of the standard color printing target, standard management, the standard of remote digital proofing color management, standards of scanning the reduction of color management, the digital camera color management, standard display correction and screen soft proofing.

(2) System implementation

Carton and carton enterprises should focus on the following aspects in the implementation of color management:

1. Standardized management of printing process

It is the premise and basis of applying ICC color management to do a good job in the standardization, standardization and data-oriented production management of each process in the whole printing process. Enterprises should strictly formulate quality standards for fine products, standards for intact raw and auxiliary materials and equipment such as paper and ink, standards for measuring tools and environmental light sources, standardized management documents, etc., and should be strictly implemented in accordance with the standards. Monitor soft proofing, PRINTER ICC file, printer parameters should be standardized, and quantified in the standards and specifications, in all places that can be expressed with data, through testing means, summed up to ensure the quality of the data. The three complement each other and depend on each other to ensure stable high quality and high efficiency production.

2. Monitor calibration and soft proofing management

Display is the most important pre-print color management tools, enterprises should choose high-quality professional display, so that the picture can be accurately presented. Using professional screen corrector and color characteristic file generation software, calibration and profile generation of the display, to ensure that the display to achieve the maximum color gamgamet and the best color rendering, and in Photoshop screen soft proofing, screen color, proofing and printing color is basically the same, to achieve "what you see is what you get" pre-display.

3. Profile file management of remote digital proofing

Remote digital proofing Profile management to ensure that digital proofs printed in different places are consistent in color. The Profile file reflecting the suitability of the printer and printer is transferred to the printer software for correction, and a new Profile file is generated after the first color space conversion. Excellent target sample, through measurement calculation and further modification, to generate the final Profile, to ensure that the accuracy of color restoration reaches more than 95 percent .

Adhere to the use of color management software to check and control the two remote digital proofing system, due to the closed-loop correction technology to form a closed-loop system of color correction, conducive to the consistency of color proofing.

The specification prints standard test strips daily for inspection and control, and conducts standardized calibration once a week. By standardizing the printer and establishing the consistency of the Profile file, the color and hierarchy characteristics of the two printers can be completely consistent. When using the same color properties file you will get exactly the same proofs.

4. Management of pre-press image processing technology

The scanning and color separation of manuscripts should be guided by the four basic standards of reproduction quality (grey balance, step reproduction, color correction and sharpness enhancement). Four standard parameters are standardized through experiments. The grey balance achieves accurate reduction and makes full use of the best field density value of dot gradation to achieve bright color saturation. According to magnification and picture content adjust to the best, so that the picture is clear, fine texture. When scanning files are completed, the defects of the improper original manuscript should be adjusted to achieve better results than the original manuscript. According to the characteristics of product design, appropriate artistic treatment, in order to fully show the artistic style of the work; It is necessary to compensate and adjust the nonlinear transfer of Paper Gift Pack printing process to enrich the printing level.

(3) Color management system configuration

At present, there are more color management systems on the market. Different color management systems have different color management capabilities for devices. Mainstream color management systems such as Adobe Photoshop color management system, Apple ColorSync color management system, Kodak color management system, etc., all have their own characteristics and strengths. Almost none of these systems can provide complete color management for the entire process of copying. Therefore, enterprises must first determine which devices need consistent color in order to make choices.

When purchasing a system, an enterprise should compare and test the reliability, device support capability, scalability, compatibility, and ease of use of the system. During the test, the same color manuscript can be used to observe which system can obtain the most consistent effect with the original manuscript in the specific operating environment.

Conclusion: Paper Gift Pack of color management implementation is combined with the conditions of this enterprise, equipment of scanner detailed test, adjustment and test repeatedly, to print the whole each link between the colour of effective information transmission and management, establish a color management system with the characteristic of the company, make the effective implementation of the color management can truly and printing the premise of quality assurance, Further improve equipment utilization, reduce costs, improve customer satisfaction, for further development of the market to lay a solid foundation.
