MGI will use next week’s Label Expo show to launch a new roll to roll press, the JETvarnish 3D Web Color + that’s aimed at the label and folding carton market. Essentially, MGI has added a print unit to its existing JetVarnish 3D digital finishing unit.
MGI describes it as a rollfed version of the sheetfed Meteor Unlimited Color that was launched last year. It’s a four colour dry toner press that has a number of finishing options, including spot UV varnish, digital foil and Semi-rotary Die Cutting. The varnish can be up to 232 microns thick for tactile effects. This is an interesting combination. The use of dry toner should allow this press to print to a wide range of substrates, without needing the more expensive coated materials, effectively pre-treating the surface for the varnish to be inkjetted. Typical applications include wine labels with hot foiling and holograms with variable data codes.
As with most of the MGI presses, it’s based on a Konica Minolta dry toner engine. (Konica Minolta already owns a stake in MGI.) It can print at up to 1200 x 1200 dpi in 8 bits resolution and runs between 10 and 20mpm across a web width of 330mm, which it has to be said is not very fast when compared with an inkjet or flexo press. However, it can also be used just for the finishing in which case it can run without printing at up to 42mpm across a 420mm width.
It uses MGI’s artificial intelligence system linked to a Smart scanner for registration.
Edmond Abergel, MGI’s CEO, says: “The JETvarnish 3D Web Color+ creates a true breakthrough on the roll to roll printing market. This new technology allows to print short, middle or long runs with 4 colors, until now impossible with traditional technologies.”
