Large format printers using UV curable ink have been among the most popular new digital printers on the market for several years by now, and the technology inside them keeps improving.

Mimaki has been using LED technology for some time now, and for good reasons. Traditionally curing of the UV ink is done using conventional mercury vapour lamps, but they consume quite a lot of power, and so produce a lot of heat – which might be too much for some delicate substrates. The Mimaki UJV55-320 uses LED (Light Emitting Diodes) at a narrow wave length selected to fit the inks used, in this case Mimaki’s LUS-120 UV-curable ink.

This is the latest roll-to-roll printer from Mimaki, and also one of the fastest. The number 320 in the name states the maximum print width in centimetres, almost 126ins. It supports twin-roll printing of up to 2x60ins rolls – another feature to increase versatility.
