Roll-to-roll printing machine

UV inkjetcolor

Gamma UV includes a series of printing machines for graphic applications where the ink used requires a drying system using UV lamps. It is a series of machines that can print from sheet to sheet, from reel to sheet or from reel to reel. The print format is on customer request and can vary from a maximum of 150x360 cm up to smaller sizes. The transport of the substrate to be printed is always carried out by means of an adhesive carpet which allows an excellent positioning capacity and guarantees an excellent register between the printing units. In the detail below we are going to describe the Roll to roll Gamma for applications of flexible materials wound in reels, for example PVC reels, where it will be possible to make mono or multi color prints.
