Heidelberg to Introduce the DryStar LE UV Solution at drupaMarch 20, 2012
Until recently, UV applications have been largely the domain of packaging and specialty printers. In the current market, however, short lead times and value-added solutions yield competitive advantages, making UV an attractive proposition for commercial printers whose customers increasingly specify non-standard (non-absorbent) substrates and a variety of specialty finishes to differentiate their products.
Scalable, Practical, Versatile
Based on the proven technology of Heidelberg’s powerful DryStar UV series but adapted for commercial requirements, DryStar LE UV is a scalable, low-energy system that facilitates entry into the UV market and opens the door to new customer segments and profitable growth. Unlike competing systems, which require the exclusive use of expensive, high-reactive UV inks, DryStar LE UV cures both standard UV and high-reactive UV inks and coatings.
The system is suitable for commercially printed products, with or without coating, produced on any Heidelberg Speedmaster press. Heidelberg’s DryStar LE UV solution is also available for specialty printing and packaging, depending on application requirements and substrates, including some limited use with PET, SBS, foils and IML.
Benefits of Common Technology
The DryStar LE UV system is fully integrated into the press at the factory and uses the same high-end technology as Heidelberg’s DryStar UV. It comes equipped with special UV reflectors that efficiently reduce the heat transfer to sensitive substrates; FLC (Fast Lamp Change); and ELC (Electronic Lamp Control). A typical DryStar LE UV commercial print configuration incorporates from one to three UV lamps. One lamp can dry up to four UV inks; at least two lamps per machine are needed to cure UV Ink & coatings. The compact supply cabinet is ideal for print shops where space is tight.
Benefits and advantages include an improved price-performance ratio and greatly reduced energy costs that promote sustainable print production. The usual benefits associated with UV printing, i.e., immediate sheet drying, minimal powder consumption, and separation in postpress, also can be achieved.
Other low-energy systems on the market use highly reactive inks and require fewer lamps; however, they also offer a smaller operating window in terms of flexibility of substrates and inks that offset much of the energy savings. In contrast, Heidelberg’s DryStar LE UV has sufficient capacity in reserve, and is therefore not restricted to a single ink series.
