In the corrugated packaging industry, printing quality is directly related to a product's market competitiveness and an enterprise's economic benefits. According to industry statistics, problems such as blurred and faint printing account for more than 35% of quality complaints in corrugated board printing. These issues not only affect product appearance but also lead to serious consequences such as unreadable barcodes and customer rejection.

DEPACK has earned high praise from customers and built its reputation through superior product quality. We deeply understand that what we deliver to our customers is not just machines, but also their trust. To ensure that each piece of equipment meets our customers' production efficiency and product quality requirements, we conduct a series of rigorous factory inspections before delivery. Taking our printing presses as an example, we conduct tests in four major areas, including the stability of the electrical system, the functionality of the equipment operation, and tests simulating production environments. The electrical components alone undergo more than 100 hours of testing before the entire machine is shipped. Let me now reveal to you the layers of checks our equipment undergoes before packaging and loading.

Flexo printing is the core process in corrugated carton production, and its printing quality directly determines the market competitiveness of finished products. In view of the characteristics of corrugated board, such as soft material and embossed surface, water-based flexo printing machines are prone to a series of technical problems during high-speed operation. Combining industry standards and frontline production experience, this paper systematically analyzes the five core faults and provides a standardized troubleshooting and solution guide for peers.
