  • Taking the lead in H-UV – Print21 magazine article

    Six of the nine Komori presses that have gone in to Australia and New Zealand in the past year are equipped with H-UV drying. The others can be retrofitted. The partners from Sydney-based Rawson Graphics installed the first Australian H-UV Komori last July and are solidly behind the new technology.

    There is no dispute about the production benefits of UV printing. Getting perfectly dry printed sheets off a press so they can be moved directly to finishing gives a new meaning to the idea of ‘print on demand’. The elimination of powder in the print drying process contributes to a better working environment and more even results. Short run-ups of approximately 30 sheets eliminate waste and save money.

    The problems arise with the side effects of using conventional UV lamps which emit ozone and odour. Print factories need to have serious ventilation to deal with the noxious gas while the smell of the print often makes it unsuitable for much indoor promotional work and packaging.

    Then there is the Komori patented H-UV print drying system.

    Rawson Graphics in Sydney was the first printer in Australia to install a H-UV Komori, a five-colour S529. That was last July, shortly after Shane Wildash, who had decided on buying the press for his own company ArtVue, merged with Lachlan Finch and Andrew Price, owners of Rawson Graphics. To say the partners are now enthusiasts for the new technology is no exaggeration. While printing the outer board wrap-cover of this issue of Print21, Price and Wildash took the time to share their experiences with H-UV.

    The new press takes its place alongside an older full-size Komori LS640 + coater. Integrating H-UV printing has changed the way the business operates and expanded the markets it addresses. It has fired a cultural change not only among the printers on the floor but throughout the whole company. As far as Shane Wildash is concerned, it is the way all commercial print will be produced in the future.

    “There are too many reasons why it is better. It dries immediately, which means it doesn’t scuff so we don’t use varnish. The colour management is much better so there is a lot less waste and we can supply print on demand in a way that was impossible before,” he said.

    The partners tell of a job for a major retail client in Sydney of 100,000 DL leaflets where the job came in at 11.00am. It was on the press by 12.00 and delivered to the city by 3.00pm in the afternoon.

    “We just could not do that job before. This press is just chewing up the work,” said Wildash.

    Another example comes with ‘clingz’ where Rawson Graphics is gaining a reputation for fast turnaround of the thin plastic sheets. Before H-UV printing the ‘clingz’ required foil inks, running in small stacks and took days to dry. Now they are ready for delivery straight away the next day.

    “Shane had never done any ‘clingz’ before, whereas we were doing them regularly every month on the big Komori, “ said Andrew Price. “Since the H-UV went in we’re turning them around in less than half of the time. Without powder they are ready as soon as they come off the press.”

    “I don’t think in 12 months we’ve reprinted a job on bad quality. There are no hickeys and the lack of spray powder is a bonus. Most of all, it changes the mindset. You go to see the production manager last July pre H-UV with what would seem to be an impossible task and he’d say ‘No, can’t be done’. Now none of the reps get knocked back,” said Wildash.

    Tip of the iceberg

    In the competitive Sydney market, expanding the scope of work you are able to do is a meaningful advantage. While the press is transforming the everyday commercial work of the award-winning company, it is also beckoning to the use of a wide range of plastics.

    “Really, this is just the tip of the iceberg. We’re testing so many different stocks and plastics with such good results,” said Price. “We are doing some good work using white ink won ReflectaKote [from Allkotes]. It’s opening new markets in flexible short-run packaging. We’re still talking with the same customers but we’re expanding what we can offer them.

    “ We’ve always had a good collaborative relationship with our customers. We can say, ‘Instead of doing your packaging on four-colour plus a metallic, why don’t you do it all on ReflectaKote?’ It really gets them thinking of the possibilities.”

    Rawson Graphics is a dynamic business with a ‘can do’ attitude. The advent of the Komori H-UV along with an HP Indigo 7500 is galvanising the company on many levels. All the stocks – paper, boards and plastics – are now tested on both new platforms. Despite the technology orientation and willingness to push the boundaries, the Rawson Graphics partners are sanguine about how technology plays in the marketplace. According to Price there is little to be gained in talking up the technology.

    “There is no point taking about digital to the clients. As Lachlan says, ‘Customers just want printing and want to deal with someone who knows what they’re doing, gives them great service and quality product.”
