The cardboard packaging production line can be configured precisely to meet customer requirements. We can configure the printing machine itself, where the machine will consist of printing segments and a feeder, or build a machine that is additionally equipped with a slotter and a rotator. Each segment can also be configured to meet customer requirements, where simpler and more cost-effective solutions can be applied, or invest in better technology. In the case of the feeder, we distinguish between several models, namely the simplest chain feeder, strip feeder, or roller feeder. Printers can be equipped with steel raster rollers and rubber rollers, or ceramic rollers instead of steel ones. The technology that ensures the most accurate ink application is the use of doctor blades on raster rollers. In this case, excess ink is collected from the roller, and a precise amount of ink is transferred to the polymer.
Another option we can choose is the way the cardboard sheet is guided through the machine. When this is done using vacuum transfer, we can be sure that the registration of individual colors will be at a high level, allowing for the printing of multi-colored images.
Another option is the inclusion of sheet cleaning sections immediately after cutting, as well as the stacking of the sheets by a machine called a stacker.
