Machines for the offset printing in upto 6 colours on flat lids of various shape and size are available. These ones, as the mod. DM 144 LIDS, feature important functional improvements that have made the system even more flexible. In particular, adaptation of the various devices to the shape of the lids has been made easier, reducing change-over times and simplifying the relevant operations. The machines are complete with all the facilities required for the printing process: from the lid magazine, to the system for the surface pre-treatment, from the UV curing system to the final re-stacker for regrouping the lids back into stacks.
