Dainippon Screen develops UV inkjet head assembly technology

Dainippon Screen, headquartered in Kyoto, Japan, has recently developed new single-pass compact UV inkjet head assembly technology.

Print on Demand (POD) enables the output of small lots of varying materials. There has been an increasing demand in recent years, not only in the commercial printing field, but also in specialized fields such as label, building material, and package printing, for higher quality Print on Demand output. Interest in UV inkjet printers that can print directly onto materials other than paper continues to increase. Technology that supports consistently high precision, quality, and productivity is essential to expanding the capabilities of UV inkjet printing.

Dainippon Screen’s development of high-quality compact 600 dpi UV inkjet head assembly technology is claimed to enable ‘consistent, high-quality output’. Since this new head assembly is more compact, the time lag between the application of the UV ink droplets and UV drying is shorter. This enables sharp printing, since it reduces both the spread of ink and the likelihood that a fringe will be generated. What’s more, the high-quality 600 dpi printing improves the legibility of small text and reduces the appearance of moir in extremely fine lines. The head assembly also features a newly developed ink circulation system that circulates the ink through the head, ensuring that the temperature of the head and the ink remain consistent.
