FLEXO Magazine : January 2010
www.flexography.org JANUARY 2010 FLEXO 33 Flexo printing---the prevalent printing process in packaging printing---can also find its way into tube printing, according to Massimo Verona from Omso SpA. of a barrier layer over the entire surface (EVOH), to reduce product costs. NEW PRESS TECH After the detour to the market seg- ment of in-mould labeling, Walter Dutly of Polytype S.A. in Switzerland concen- trated on direct printing. He specified new developments in the field of printing machines and described where the machine manufacturer 's responsibil- ity lay regarding migration, and which individual parameters are exerting influ- ence in this respect. After Dutly, Sigfried Joneleit, also from Polytype SA, picked up on the subject of tube printing with flexo presses. He defined the challenges is- sued to the process in this market sector. FLEXO FOR TUBE PRINTING The main focus of Massimo Verona's (Omso SpA) presentation was the question of whether flexo printing---the prevalent printing process in packaging printing---will also find its way into tube printing. The speaker went into detail and portrayed the history of the proce- dure and explained the process with its individual parameters. He referred to the advantages that, for example, the narrow web industry are utilizing for labels. However, here the applied roll-to-roll production is carried out on webs in the wet-on-dry procedure. This process, he noted, holds many disad- vantages with the printing of tubes. Verona then went into what a machine for cup printing would have to look like. His suggestion: a circular arrangement instead of a linear configuration. UV MEASUREMENT: SAFETY + UV technology plays an important role in safety in cup and tube print- ing. Reto Huber from Uviterno started his lecture by describing the recent tightening of safety regulations for print- ing plants. To keep in compliance, he recommended UV measurement. He explained the important criteria for UV measurement, such as degree of effi- ciency, dose, performance or reflection. Huber reduced it to the simple for- mula: "Where, what, how, and by which means." In other words, "Where to be measured, what to be measured, how to measure it and by which means?" In addition, there are numerous param- eters influencing a measurement. These include the range in the UV spectrum, device and position of device, as well as settings of the press and UV system. Concluding the event, Huber refer- enced LED UV technology, which he claimed just might be the future of the industry. But his explanations also con- firmed that it is still a long way before such devices have a practical use in cup and tube printing.
