In the most modern UV LED module production facility: The gold wire bonder, used for the electrical contacting of the UV LED chips, is at the heart of the production process. It produces very robust connections, exceeding even industrial standards.

HANAU – Heraeus Noblelight, a specialist for industrial light source solutions, supplies UV LED curing systems for Peak Performance Speedmaster printing presses of Heidelberger Druckmaschinen Aktiengesellschaft. This DryStar LED curing system was developed in close cooperation and equips today now more than 1.000 printing units with more than 250 UV LED bars. Heraeus Noblelight’s innovative ultraviolet and infrared light source solutions are tailored to the needs of Heidelberger’s printing presses and deliver reliable, powerful and efficient drying and curing processes.

Increasing production and expanding printing capabilities

DryStar LED and other products of the Heraeus UV LED family “Semray” feature special micro-optics on the LED arrays that gather and optimize UV radiation and minimizes stray light. The UV LED curing unit delivers up to 30 percent more active UV energy to the product which results into high printing production speeds and the ability to print onto heat sensitive substrates. The negative impact of heat in the process can be eliminated. Printers using the new LED curing technology can take on new kinds of print jobs to expand their customer base and grow the business.

“The system runs at lowest energy consumption and still delivers highest performance during stand-by, wash-up cycles and make ready times. It automatically reduces power consumption close to zero”, says Martin Zibold Product Manager DryStar -Technologies at Heidelberg Sheetfed.

When entering the sheet size at the Prinect Press Center, Auto Format Setting sets all LEDs in the bars automatically according to lateral and circumferential direction of sheet size - up to an accuracy of 1mm. This results in additional energy savings of up to 40% during standard sheet size production, sheet by sheet.

“The smart temperature management of a DryStar LED cooling device adds additional savings to the energy calculation. In this precision a unique and outstanding advantage for achieving high productive and ecological UV curing results at lowest energy consumption costs,” says Frank Mohr, Key Account Manager for Heidelberger Druckmaschinen at Heraeus Noblelight.

The unique technology of Heidelberg’s DryStar LED system is designed for high demanding requirements of Heidelberg’s sheetfed offset printing applications: it delivers the highest dose at a high working distances due to its revolutionary optical concept. DryStar LED achieves the best curing results even with high ink and coating coverage rates on paper and board no matter if coated, metalized or uncoated, even more on heat sensitive materials like plastics or foils. Combined with a higher up-time production range and no waiting times with Instant-start-and stop functionality the system can provide optimized price/sheet or sheet/hour performance, compared to traditional technologies.

From the most modern UV LED production facility in Europe

Heidelberger Druckmaschinen Aktiengesellschaft is well known as a reliable and highly innovative partner to the global printing industry for many years. State-of-the-art technologies in combination with modern innovative business ideas prove their success.

Producing high-quality print products requires top-quality printing processes with optimized production processes. Printers who can offer quality prints with new and attractive applications at reduced delivery times are able to expand their capabilities, differentiate themselves from their competition and grow their business. Heraeus Noblelight develops innovative UV LED curing systems for commercial printing processes to fulfill these requirements. At its headquarters in Hanau, Heraeus develops and produces the UV LEDs for these high-speed printing applications. This most modern UV LED module production facility in Europe incorporates the latest lean and quality standards. It even includes clean-room technology with class ISO 14644-1 / ISO class 4. The professional manufacturing infrastructure and the in-house chip-on-board (COB) line contribute to very reliable LED array. Additionally, Heraeus’ UV LED R&D and production leverage easy access to high-quality materials from the Heraeus technology group to produce innovative and high-quality solutions.
