UV Flexo Station	An integrated flexo station for full size sleeve coating inrotary. This station is used to apply a UV protection varnishor primer prior to finishing. The module comes with an UVdryer. The station is equipped with an anilox cylinder.Additional anilox cylinders are available as upgrade options.
Spot UV Coating andEmbossing Station	This station uses MGI award-winning inkjet technologyfor producing Spot UV Coating. Any defined label area canreceive Spot UV Coating with or without raised 3D textureeffects. A simple grey level TIFF file designed by Prepresscontrols the surface area and the thickness of thevarnish applied over the printed roll. This 100 % digitalprocess eliminates traditional plates, screens and dies.
Varnish thickness	From 7² to 232² μm of varnish thickness(from 2D flat coats to 3D raised effects).
Inline curing	The unit is equipped with an UV dryer and a coolingdrum for optimum web temperature control. The curingsequence also includes a special forward and backward rollmotion to dry each label and eliminate waste between runs.
UV Varnish	Gloss varnish 99 GU
Hot Foiling Station	The hot foiling station adds luxurious effects and brandvalue to label and packaging products. Any defined labelarea can receive digitally-controlled foil with or withoutraised effects.A simple grey level TIF file designed by Prepresscontrols the surface area and the definition of the foilapplied on the printed roll. This 100 % digital processeliminates traditional dies, plates and screens.Foil application can be bypassed when not necessary.
Foil rolls	Foils are delivered on rolls:Foil widths from 100 mm up to 420 mmFoil roll core diameter: 1’’ and 3’’Foil lengths from 400 m up to 2,000 mUp to 3 rolls can be used simultaneously duringthe production
