Pigment box packaging products often appear in the actual production problems of reducing color, such as neutral gray, affecting product quality. In addition to equipment itself, production technology level, a key problem is that enterprises fail to carry out effective ink color management and reasonable application.
Implementing color management
Generally speaking, a packaging printing enterprise needs a standard environmental light source; 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 proofing color management; standard scanning. Recovery, digital camera color management; standard display calibration and screen soft proofing. In the implementation process of specific color management, the following aspects should be done well: the whole process of printing standardization, standardization and data production management, which is the premise and foundation of ICC color management.
Strict implementation of quality standards
Enterprises should strictly formulate fine product quality standards, complete raw and auxiliary materials and equipment standards such as paper and ink, measuring instruments and environmental light standards, formulate standardized management documents, and require everyone to strictly comply with standards. Printer display, soft proofing, ICC files, printer parameters and so on should be standardized and quantified within the scope of standards and norms. Data can be represented by data, and quality data can be summarized by testing. The three complement each other and depend on each other, which ensures stable, high-quality and high-efficiency production.
Pre-press image processing technology is the basis and key link of printing reproduction quality. The display should be professional. The original scanning and digital manuscript processing should be unified and the four basic standards of manuscript quality (gray balance, step-size reproduction, color correction, sharpness enhancement) should be used to guide the work, and the four standard parameters should be standardized through experiments. After the scanning documents are completed, the inappropriate defects of manuscripts are artistically adjusted and handled to enrich the printing level and achieve better results than the original. For remote printing enterprises, the management of remote digital proofing profiles can ensure the consistency of digital proofing colors between the two places.
