Tresu Group is enhancing the flexibility of the digital folding carton printing workflow with the introduction of the iJet inkjet coater for variable inline application of UV spot varnishes.

Positioned after the printing stage, the 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.

The 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, iJet achieves speeds of 58 metres per minute or 4600 sheets per hour, and uses specially formulated UV varnishes that offer high gloss and scratch resistance.

Kim Krintel, vice president, Tresu DigitalSolutions, commented: ‘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 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.’
