Drying, Curing & UV SERVICE MAKES SENSE


UV drying systems work to their optimum only if they are properly maintained and serviced. Chris Schofield, joint managing director of IST (UK), offers his top tips


Jonathan Simpson, an IST (UK) engineer on location


industry has matured into a highly technical and productivity- focused business, the ROI of good maintenance and servicing has been appreciated. Production management do


A


undertake regular press maintenance but they ignore the drying units at their peril!


A service contract provides peace of mind


by eliminating unexpected and expensive call outs but it also ensures that the print quality and productivity is always at its optimum. Preventative service is cheaper and more effective than the “don’t stop ‘til you drop” approach. This applies whatever form of UV you might choose for your labels or packaging, conventional or LED-UV. Maintenance on any drying device means


keeping reflectors, lamps and filters clean. This should be done by the operator weekly and is very straightforward. IST (UK) engineers demonstrate how to do it easily and safely when they install new systems at a plant.


IST (UK) also offers a range of service agreements, from general maintenance


s the packaging printing


packages, including minor and major services, through to comprehensive options with extended full parts and labour warranty. The standard package involves two visits


a year to the printing plant. For the minor service one engineer would attend and the focus would be on cleaning and inspecting. The reflectors and cooling circuit would be cleaned and checked and performance monitored to ensure the system is running to its start up protocol. It is also a chance to monitor what might need to be implemented at the major service which is undertaken by two engineers. Cassettes are stripped down and pneumatic and water systems are checked. If needed, the cooling water can be flushed out and new water added with the correct amount of corrosion inhibitor. An ozone test can also be carried out to certify the system is correctly exhausted through the building or through a carbon scrub. One packaging plant which chanced its luck and ran an older system for six of seven years with minimal, if any, maintenance ended up paying more than they would have done with a service agreement to put everything right. They had probably compromised their printed results and output in that time and when the failure occurred it took IST two days to

recover the situation which meant that the packaging printer had to deal with unplanned downtime which is never great for customer relations. IST (UK) has its own engineers who, unlike


freelance engineers, are up to date with the latest technology and have access to software and pin-protected service pages on the control screen. When using IST engineers, printers are tapping into a qualified team with a combined 40 years’ experience and they can be certain that the safety circuits all work correctly to current legislative standards. These same engineers will also handle


retrofit work, a great way to upgrade an existing press with UV or LED-UV without fully replacing it. It allows printers to enter the UV market or to trial LED-UV, a low energy option that is gaining ground. The retrofit for a conventional UV unit


would be five to six days but for LED-UV could be completed in one or two days. All retrofits are provided with a 12 month warranty and printers can extend that with an IST (UK) service agreement. IST (UK) is happy to help with a
