Seeking answers to today’s issues
Implementing the H-UV system across a broad swath of the Komori product lineup and testing the materials and articles that will drive Komori’s PESP initiative have made the R&D Center a hub of trusted know-how.

The Printing R&D Center endeavors to find answers to the new needs and issues confronting users. The results of its research and development include collaborating with various other manufacturers and developing printing software. In the past five years, the Center has worked principally on creating the H-UV system and promoting standardization based on printability tests aimed at optimizing printing materials such as blankets, inks, varnishes, coater plates, wash-up solvents and dampening solution additives. Research results are communicated both throughout the Komori Group and to outside parties. The H-UV Innovative UV Curing System is a technology that arrived just as the Komori Graphic Technology Center was inaugurated, and the development of this system and the growth of KGC have been inseparable ever since. In just three and a half years, Komori has shipped more than 200 H-UV-equipped presses to users in Japan and more than 100 such machines to printers overseas, with over 40 presses in Europe alone. The range of H-UV-specified machines includes 4-10 col, B1 and B2, presses with and without coaters.

H-UV’s wide-ranging benefits
This exciting technology is outstanding in its advantages for the environment — using a low-power lamp that emits no ozone, offering powderless operation that is free of VOCs, and affording recyclability of printed work. The system also overcomes bottlenecks in printing due to the slow turnaround of conventional oil based inks relying on oxidation and polymerization (natural drying). H-UV allows work to be immediately processed in the bindery and therefore requires no drying time. The print quality attainable with H-UV is outstanding because there is no damage to the prints as a result of ink set-off in the delivery. And since the process is powderless, machine maintenance and downtime is reduced and work can be sent to postpress finishing immediately for cutting and folding. Furthermore, ink usage is reduced because there is no ink no dry- back and therefore what you see in the delivery of the press is what you get!

Structurally speaking, the equipment is simpler than existing dedicated classic UV presses. In fact, in every respect, H-UV has been a major success and is revolutionizing print culture across a wide range of applications. Users report significant satisfaction with H-UV and are taking advantage of its many benefits. For example, the productivity improvements that result from installing an H-UV-equipped press allow some customers to return work in house that was previously outsourced with the resultant cost benefits. KGC has also taken charge of implementing technological improvements in collaboration with manufacturers and directing the transfer of technology to overseas subsidiaries and distributors. The results of these efforts were recognized by honors such as the Technology Prize of the Japanese Society of Printing Science and Technology and, within Komori, the President’s Special Award.
