In the prepress system, the digital process is the core. The hardware system technology such as plate-making machine has matured and its performance is stable. Therefore, the key to whether it can match the production mode of the printing plant and ensure efficient and stable production lies in the digital process.
The foundation of the digital process is color management. The role of color management is not only to obtain reliable digital proofs, but also to ensure that the printed colors are accurately reproduced according to customer expectations, and to optimize the printing production process to ensure the smooth progress of printing production.
The premise of color management is the stabilization and digitalization of print production. In the traditional film printing era, the creativity and technical level of printing masters determine the quality of printing reduction. In the CTP era, the only requirement for a printing garage is stability. Stable printing density, stable printing dot expansion curve, and stable reduction of printing plate dot.
The key points of quality control in printing plants are shifted from printing to pre-press. The digital process based on color management manages the printing plate output and determines the printing quality. In the past, printing companies paid more attention to our printing standardization (in-factory standards). The current trend is to achieve international printing standardization. The biggest advantage of achieving international printing standards is that they have a common language with print buyers, and everyone has a common expectation of colors. Even documents and digital proofs processed by different systems can accurately predict printing colors.
The stabilization and dataization of the printing garage is the standardization of printing. How to achieve international printing standards? In short, it is "knowing yourself, knowing each Other, optimizing and stabilizing". The so-called "confidante" is to first understand your own status, including printing materials, printing equipment, process parameters and so on. "Zhibi" is aimed at international printing standards, and "optimization" is to formulate printing process parameters and plate output curves to achieve printing standards. "Stability" is the basis for achieving standards, keeping materials stable, production process stable, and printing quality stable.
Restricted by the cost of printing materials, many printing companies need to achieve international printing standards, but the printing materials (such as paper Baidu, ink color, etc.) do not meet international standards, how to achieve printing standardization? The printing materials are not standard, but need to be stable. The batch has the same index parameters. At this time, it can be understood as the internal standard of the factory (based on specific printing materials and production process parameters, stable production). With the help of the color management system, it can maximize the effect of international printing standards.
