The problems of packaging box manufacturers in product printing production

Color reduction issues often occur in the actual production of color box packaging products, such as neutral gray color deviation, which affects product quality. In addition to the problems with the equipment itself and the technical level of the production personnel, the key issue is that the enterprise has failed to effectively manage color and apply ink reasonably.

Implementation of Color Management

Generally speaking, to do a good job in color management for packaging and printing enterprises, it is necessary to have standard environmental light sources; High quality color feature file generation software; Advanced color management system; Standard measuring instruments and testing tools; Standard color target; Standard printing management; Standard remote digital sampling color management; Standard scan restoration; Digital camera color management standard display calibration and screen soft proofing. In the specific implementation process of color management, the following aspects should be done well: standardization, normalization, and data production management of each process should be carefully carried out throughout the printing process, which is the prerequisite and foundation for implementing ICC color management.

Strict formulation of quality standards for refined products

Enterprises should strictly establish quality standards for excellent products, paper, ink and other good raw materials, auxiliary materials and equipment, measurement tools and environmental light source standards, and develop standardized management documents, requiring everyone to strictly follow the standards. In all places that can be represented by data, standardization and quantification of display, soft proofing, printer ICC files, and printing machine parameters are carried out through testing methods, and data quality is ensured by summarizing through testing methods. The three complement each other and depend on each other to ensure stable, high-quality, and efficient production.

Pre press image processing technology is the foundation and key link of quality

Pre press image processing technology is the foundation and key link of printing and reproduction quality. The display should be specialized, and the scanning of the original manuscript and the processing of the digital manuscript should be guided by the four basic standards of reproduction quality (grayscale balance, sequential reproduction, color correction, sharpness enhancement), and the parameters of the four standards should be standardized through experiments. After scanning the file, it is necessary to adjust and handle the defects of inappropriate manuscripts to enrich the level of printed products and achieve better results than the original manuscript. For enterprises printing in different locations, remote digital proofreading archive management can ensure that the color of digital samples between the two locations is the same.
