Complexity of printing and post-printing suitability In packaging printing, on the one hand, different substrates, different printing plates, and different inks have different printability; on the other hand, in order to protect the printing surface, improve the surface Gloss, and get special visual effects, often after printing, but also for such as coating, laminating, bronzing, indentation, die-cutting and other post-press processing. Therefore, higher requirements are placed on the printability and the suitability of postpress processing of packaging printing. This requires a comprehensive understanding of the suitability of printing and post-press processing. It will continue to summarize and accumulate experience in order to obtain good printing and post-press processing results.
High-quality and high-efficiency products In general, the main functions of packaging and printing are to beautify and promote products, promote sales, and increase sales value. Therefore, the quality of packaging and printing products mostly belongs to medium and high-end products. In addition, in order to maximize the quality of printed products, new technologies, new processes, and new materials are often first promoted and applied in packaging and printing, so that the quality of printed products is always in a leading position. In other words, packaging and printing occupy the market with high quality and gain high efficiency with high quality. This is also one of the important reasons why the packaging and printing industry has attracted worldwide attention in the past decade or so.
