May 7, 2004 -- The German Institution for Statutory Insurance and Prevention in the Printing and Paper Industry (Berufsgenossenschaft Druck und Papierverarbeitung) has honored the Speedmaster CD 102 from Heidelberger Druckmaschinen AG (Heidelberg) with the new "Optimized UV printing" test certificate at drupa 2004. This certificate establishes that the requirements of the largest European institutions for statutory insurance and prevention and those of the UV protocol recognized throughout the industry are met. With the innovations now also available on Speedmaster CD 102 UV models, Heidelberg is able to offer a comprehensive package in the 70 x 100 cm format range, thus making it easier for customers to enter into and gain expertise in UV printing. Aspects such as the performance, ease of operation and energy efficiency of this generation of presses have undergone further optimization. At the end of 2003, the Institution for Statutory Insurance and Prevention in the Printing and Paper Ind! ustry had already recognized the impressive technology on the Speedmaster CD 74 UV. And now the Speedmaster CD 102 also meets the criteria required for the award of this certificate.
The UV protocol goes much further than the minimum statutory requirements and describes how an ideally equipped UV press should look in terms of health and environmental protection and operator safety. What's more, the new test certificate includes the familiar "Emission-tested press" certificate and confirmation that the safety standards of the GS test certificate have been met. Safe compliance with these requirements means that emissions are less than one tenth of the statutory limit values.
"This certificate is of particular interest to newcomers to UV printing," explains Dr. Klaus Spiegel, Member of the Heidelberg Management Board. "It lets us show that UV printing is just as safe as traditional offset printing," continues Dr. Spiegel.
Increased energy efficiency
The UV lamps can now be positioned approx. 20 percent closer to the sheet thanks to improvements in sheet transport and flow-optimized gripper bars in the new Preset Plus delivery. As a result, the effectiveness of UV hardening increases by a power of two, which in turn has a positive effect on the production speed and level of gloss that can be achieved. Moreover, the latest URS (UV-Reflector System) reflector geometry from IST Metz GmbH enables an increase of approx. 20 percent in UV output at the same level of electrical power. The UV end-of-press dryers from IST are now generally fitted as single cassette slide-in modules, which allows selective control and use of different reflectors so as to enable the best possible adjustment for a wide range of UV applications.
The UV dryers are compatible with the latest DryStar 3000 generation from Heidelberg and can be easily serviced on the operator's side of the press at an ergonomic height. And another completely new innovative feature is that all supply connections for high voltage, control voltage, compressed air, exhaust air and cooling water are connected automatically when the slide-in dryer module is put into operation. There is no need to connect any of the lines manually, which in turn reduces press downtime when cleaning the reflector and UV lamp. And the new FLC (fast lamp change) function enables cable-free lamp changing in a matter of seconds.
Fully integrated control concept and smart safety technology The central press control link and automatic recognition of the dryer modules (plug-and-play) via CANopen now both come fitted as standard. And all settings for the slide-in dryer modules can be stored in the press using the new DryStar Advanced software module. Depending on the job structure, they can then be applied for repeat jobs, thereby cutting make-ready times significantly.
The SmartGuard UV function, which enables selective querying of all protection and safety devices, is a further world innovation from Heidelberg. The UV dryers are only switched off independently of the press emergency stop function if this becomes necessary for UV protection considerations. Otherwise, the dryers go into standby mode. This not only increases press availability, but also the service life of the lamps. Switching off the UV dryers during blanket washups is also avoided thanks to the InstantStart UV function.
Heidelberg is presenting additional possibilities for UV light printing in conjunction with IST Metz GmbH at drupa in the UV Technology Center in hall 3.
