TechnologyKomori Impremia IS29 Sheetfed UV Inkjet Digital Printing System
The Komori Impremia IS29 is a 29-inch (B2 size) sheetfed digital printing device combining the consistent capabilities of digital inkjet printing with the sheet perfecting and durability of Komori's offset presses. The IS29 offers razor-sharp photos and text, high-quality color blocks, and instant curing of UV inks, making printed sheets immediately ready for finishing and reducing the need for additional postcoating of mail pieces. It was developed in partnership with Konica Minolta and uses a Konica Minolta inkjet system and digital front end (DFE). The 1200 x 1200 dpi piezo-electric print heads produce multi-level droplets of UV ink down to four picoliters in size.
The IS29 was designed to address market demand for an inkjet device that can produce 6-up imposition of full-bleed letter documents while integrating the sheet perfecting mechanisms used in offset presses. The innovative adaptation of this technology to a digital printing device gives the IS29 the same front-to-back, single-pass perfection of sheets on the fly. Other B2 inkjet presses require two passes to print a two-sided sheet. Instant curing of the UV ink enables immediate handling and finishing of the perfected sheet. Using LED curing technology, the UV ink is instantly "dried" on the surface of the project substrate with a durable ink film, giving the IS29 the ability to print on a wide range of substrates without pre-treatment of stock or additional post-coating. This substrate diversity includes many plastics and synthetics previously done only on wide-format machines. In addition, the IS29 can reduce makeready time, as the first sheet printed looks exactly the same as all the other sheets in a job. All of these elements combine to make the Impremia IS29 capable of short-turnaround, on-demand printing projects.
