OMSO Axial

Screen printing on containers can be challenging work, even if the job only involves a single color. But, applying multicolor graphics 360° around a product's surface?  Now you're talking high stakes. And when container surfaces are irregular and the job involves large quantities, only printing systems designed to accurately transport parts, maintain tight registration, and effectively handle pre- and post print processes will be able to fulfill demands for quality and productivity.

OMSO engineered its Axial automatic container decorating system with these considerations at the forefront. In fact, the company says it's the first built specifically to print multicolor graphics and apply pressure sensitive labels 360 degrees around container at high speeds.

Axial is a modular, automatic screen-printing and pressure sensitive labeling machine that can accommodate container diameters of 0.79-472 in. (20-l20mm) and lengths of 1.57-12.6 in. (40-320mm). The system offers a 12.6-in. (320-mm) maximum print length and 9.84-in. (250-mm) maximum print height.

Servo technology and a computerized control system with a graphical touch-screen interface drive the Axial. Job set up involves teaching the press how to handle the products which includes scanning the object's surface with a laser. A print simulation generated by the machine's software based on the scan can then be reviewed and adjusted if necessary.

Once the container has been positioned for printing, its movements are controlled by special drives and synchronized according to tabular mapping processed by Axial's Software. Axial's software uses a dedicated algorithm to synchronize the movements of the press's motors. This allows the container, screen, squeegee and label head to operate together without slipping. The container turns around its axis and can also move vertically. The screen and squeegee unit move horizontally, and the squeegee is always perpendicular to the container. During the curing process, the container is rotated so that the entire surface is exposed to UV-curing energy. Once completed the product is then passed through a vision inspection system where defective bottles are ejected.
