With a printing speed of 6,000 sph for single-sided printing, the J-throne 29 realizes the world's highest-class ROI

The new J-throne 29 broadens Komori's digital press portfolio, which already includes the Impremia IS29s, a 29-inch Sheetfed UV Inkjet Digital Printing System, and the Impremia NS40, a 40-inch Sheetfed Nanographic Printing® System.

The press is rated for 6,000 sph in single-sided printing, boasting the fastest printing speed in the B2+ size inkjet press class.

The imaging technology incorporates Komori's proprietary image forming technology. Additionally, the newly developed UV ink will provide printing capability on a wide range of substrates such as coated and uncoated paper and paperboards without pre-treating, making it valuable to the commercial, packaging and specialty print markets.
