Düsseldorf, Germany, 9 June 2016: TRESU Group (Hall 10, Stand D54) enhances the flexibility of the digital folding carton printing workflow with the introduction of the TRESU iJet inkjet coater for variable inline application of UV-spot varnishes.

Positioned after the printing stage, TRESU iJet is designed to integrate seamlessly with the HP Indigo 30000, HP Indigo 12000 and HP Indigo 10000 digital presses. It processes the same software as each of the presses and, where necessary, the accompanying analogue coater. As a result files are ripped in minutes.

TRESU iJet can be customised to accommodate any number of printheads, between one and 11, along the bar. The printheads can be repositioned in the cross direction, to apply coating anywhere on the package.

Matching the productivity of the printing press, TRESU iJet achieves speeds of 58m/min or 4,600 sheets/hour, and uses specially formulated UV varnishes that offer high gloss and scratch-resistance.

Kim Krintel, vice-president, TRESU DigitalSolutions, comments: "Spot varnishes are an effective way of adding impact to an underlying image, thereby increasing the package's overall aesthetic appeal. The arrival of the TRESU iJet coater, with minimal prepress times, provides an efficient solution for applying spot coating in short-run situations or on variable features of the package, for example on personalised products. Additionally, it enables printers to offer more sophisticated branding in situations where time-to-market is of paramount importance, such as in the case of prototypes and market trials."

TRESU iJet is being demonstrated in a digital folding carton printing – coating line on the HP drupa stand in Hall 17.
