Using Herma self-adhesive materials and HP Indigo digital printing technology, AB Graphic has produced a new sample catalogue containing abstract and highly complex label shapes to showcase the redesigned Digilase Series 3 laser die-cutting system. The Digilase Series 3 features enhanced precision, allows job changeovers on the fly and significantly improves efficiency. The laser heads have been replaced for enhanced cutting performance and can accommodate the widest range of substrates. The only consumables that need to be changed are the filters of the fume extraction system, according to AB Graphic. The labels for the sample book were designed and printed on rolls by HP Indigo in Barcelona, Spain before being produced for the sample book by contactless laser die-cutting. “Herma’s premium variety of self-adhesive materials we used delivered outstanding results with our HP Indigo Electroinks printed on the HP Indigo 8000 and the HP Indigo WS6800,” said Teresa Baena, Pre-Sales Technical Consultant for HP Indigo Labels & Packaging at the HP Experience Center in Barcelona.
In choosing the material, an important consideration was uniform adhesive application. Fluctuations of around +/-3g/sqm in the material are not unusual, which can give rise to variances of as much as 15% with the quantities of adhesive that are generally applied. Herma noted that, for laser die-cutting especially, such inconsistencies can trigger unsatisfactory results when removing the cutting waste. AB Graphic pointed out that as laser die-cutting delivers the exact amount of energy required to remove both the substrate and the adhesive layer without damaging the liner, a high precision is required in the production of the liner paper and label material, while as little variation as possible in the adhesive is crucial. Dr. Ulli Nägele, Head of Development at Herma, added: “Special curtain coating enables us to apply extremely consistent coats. A discernible transverse section, consisting of peaks and valleys of adhesive, no longer exists.” The sample book marks the launch by AB Graphic of the completely redesigned Digilase Series 3 laser die-cutting system. Floriana Montella, Business Development Manager at AB Graphic, added that “the redesign gives label producers and users fresh scope to create innovative label formats. Our new samples clearly demonstrate how unusual labels with striking special effects and eye-catching elements can be used as effective marketing tools.”
