FLEXO Magazine : August 2012
Be sure to flush in both directions and repeat as necessary. Debris can get trapped in one direction and will only come dislodged when flushed in the opposite direction. Failure to do so may set you up for damage in the near future, as the debris gets free en masse, or one sliver at a time. Debris can get trapped in some pumps. Once you get your press, do you have instructions on how to use the equipment properly? Are there any hazards you need to be made aware of? A great example would be the build of the enclosed chamber. While a simple process, some- one building the chamber must understand the importance of the blade laying flat and the need to sustain a clean, pristine blade-rest area. During the assembly, this is the perfect time to address training and take every opportunity to get “hands-on” before the clock starts ticking on production demands. Practicing the proper methods of changing blades and end seals can avoid costly anilox damage. Timing is everything, so if you require outside resources, please plan ahead so you have everyone and everything you need at your fingertips (anilox, sleeve, doctor blade, cleaning and other seminars). The extra effort will pay off later in day-to-day operations. Develop a simple checklist for press assembly/testing: • Examine need for added cushion points in press, storage and transportation of aniloxes • Flush ink storage/dispensing system, ink delivery system and wash-up • Use old anilox for initial deck calibration/setup • Time all automated wash-up cycles to make sure rotating anilox is kept wet the full length of the engraving • Double check all decks to make sure they do not rotate dry while waiting for ink • Perform ink pump maintenance, including hose changing and adjusting pump speed or flow setting • Distribute instructions on chamber and blade handling— calibration, assembly, installation, removal and cleaning An overlooked area of concern is press modification, monitoring and debris control. Make sure there is a proce- dure in place that covers the drilling of all holes and grinding of any accessory installations. The shavings created must be contained; simple ways to address the issue include magnets, grease or even double sided tape near the area. Never blow off machining area, as it will scatter the debris and make it impossible to account for all of it. Unaccounted- for shavings can fall, become trapped and later on become recurring anilox damage nuisance. DAY-TO-DAY OPERATIONS Day-to-day operations can be defined as processes in mo- tion. How well your processes function and whether there is participation and engagement to make sure workflow proce- dures are followed are your two primary concerns. Your press operators, supervisors and managers must have full involve- ment or the desired process outcomes will not be sustainable over the long term. Ben Franklin also said this about getting participation and engagement: “Tell me and I forget. Teach me and I may remember. Involve me and I learn.” It is not enough to put your whole pressroom in motion without auditing and diagnosis, so you must have a way to check your processes. Schedule a one month and two month follow-up meeting for the implementation team. You can certainly have your own auditing system set up, but you might want to take additional advantage of external review. Having a second set of eyes, especially from an external source, often helps you pinpoint conditions that need to change. Your suppliers often have people who are trained and certi- fied to do press-area audits to help make sure your imple- mentations are successful. Don’t be shy about utilizing them. When it comes to anilox processes, monitor how aniloxes are being used, cleaned, installed, removed, stored and trans- ported. Check peripheral items of the inking system, like doc- tor blades for wear and slivers; check ink magnets and filters for debris. It is a good practice to have the operators keep a log of all blade and filter/magnet maintenance, many of the new presses have available screen tabs for this purpose. Here is a day-to-day auditing checklist for anilox rolls/ sleeves: • Are designated practices being followed? • Is documentation filled out properly and consistently • Confirm chamber pressure (when possible use 1/8-in. red tape and add to pressure gage at the maximum allow- able pressure) • Perform a used blade analysis to double check blade wear and alignment of chambers 74 FLEXO august 2012 www.flexography.org © tesa tape, inc. www.tesatape.com ISO 9001:2008 Certified • ISO/TS 16949:2009 Certified • ISO 14001:2004 Certified ® • Plate Mounting • Roller Wrapping • Splicing • Core Starting • Edge Sealing • End Tabbing • What Every Pit Crew Needs NEW tesa Softprint® FE Plate Mounting Tapes tesa EasySplice® FilmLine PLUS Splicing Tape NEW What Every Pit Crew Needs What Every Pit Crew Needs Introducing Speed and Efficiency for Your Print Crew n Fast mounting n Splice at high speeds n Easy de-mounting n Improved adhesion n Superior print quality n Increased throughput InquireforFREESampleemail@example.com Official Adhesive Tape Sponsor tesaFLEXO8x10.875PrintAd2012SQR.indd 1 1/20/12 11:41 AM You do not need a large press area footprint to store your anilox properly.
