Technologies & Techniques The Flying Splice understanding the Critical Role it Plays in Today’s Printing Process By Joe Prunier Today ’s sophisticated package printers are continu- ously challenged to provide more complex products in shorter timeframes. They focus on two main criteria to define their success: speed and efficiency. In short, those fac- tors determine whether or not a printer is profitable. To reduce cost, many printers are using thinner and higher slip film stock to maximize packaging processes and efficien- cy on “form, fill and seal” systems. While so much attention is focused on speed and efficiency in the printing process, the practices by which roll stock is changed on high-speed presses deserves equal attention. Companies spend millions of dollars on presses that are capa- ble of running at speeds of up to 800 mpm or more, an impressive figure. If, however, the process to change roll stock during a pro- duction run is not successful, the efficiency gains of a high-speed press quickly evaporate due to a failed roll-to-roll splice. CHANGING ROLL STOCK RAPIDLY • There are currently two ways to splice roll stock; manual static splicing and automatic flying splicing. • If the process to change roll stock during a produc- tion run is not successful, the efficiency gains of a high-speed press quickly evaporate due to a failed roll-to-roll splice. • Automatic roll-to-roll flying splice systems allow for continuous operation of the press without stopping or even slowing the press down to change rolls. • To maximize speed, decrease down time, and avoid splice breaks that can obliterate all high-tech effi- ciencies, it is vital to have a simple and easily repeat- able standard operating procedure (SOP) in place to ensure all splices are prepared properly Photo: tesa tape www.flexography.org oCToBeR 2011 FLeXO 29 HD FLEXO www.esko.com firstname.lastname@example.org Visit us at: LabelExpo Americas 2010 14-16 September - Chicago Stand: 5202 The new quality benchmark in flexo printing HD Flexo combines high resolution imaging with advanced screening.
