Omet has designed a hot foil unit that slides on rails to increase the production potential of its X-Flex machine system. The new unit can be deployed quickly and at any position in the printing process, without having to give up the use of a flexo unit. With the X-Flex automatic pre-register and vision control, adjustment is automatic, reducing the time needed to prepare jobs and cuts down to a minimum wasted material at start-up. The optional tooling device that is integrated in the unit improves both setup time for the machine and operator safety. It allows for easy removal of the printing cylinder. A new printing roll can be prepared offline, using the optional change trolley, equipped with a worktable.
