The manufacturer announced the release of the new presses, which are powered by High Definition Nozzle Architecture (HDNA) technology, at Graph Expo, which is being held this week in Orlando, Florida.
The new models include the PageWide Web Press T390 HD, which is being shown at Graph Expo, as well as fellow colour machines the T380 HD and T370 HD and the mono T390M HD.
They have replaced the original T300 Series Inkjet Web Presses, which were launched at Drupa in 2008, by upgrading the technology in those machines to HDNA, bringing the 762mm T-Series presses in-line with the 559mm and 1,067mm models that have already been upgraded to HDNA over the past year.
HP said the new machines close the quality and performance gap between digital and analogue technologies and enable printers to shift more work from offset presses to reduce waste and makeready times, and to streamline supply chains.
The new presses can handle media widths of 203mm to 762mm, including a range of standard uncoated offset media, inkjet-optimised coated media, ColorPro media and offset coated media with HP Priming Solution in thicknesses from 40gsm to 350gsm.
Each of the presses uses water-based HP pigment inks and bonding agent. The HDNA technology used in the presses offers a native resolution of 1,200dpi, delivered by 2,400 nozzles per inch.
In performance mode the maximum speed of the T390 HD is 305m/min, the T380 HD can print at up to 244m/min and the T370 HD has a maximum speed of 183m/min. In quality mode all three presses can print at up to 152m/min.
The mono T390M HD can print at up to 305m/min in performance mode and up to 152m/min in quality mode.
HP PageWide Web Press Division worldwide director of marketing and business development David Murphy told PrintWeek: "The benefits of HDNA technology are increased image quality and enhanced productivity.
"It opens the door for new kinds of high-quality applications that include magazines, catalogues, high-quality marketing collateral, posters and the like. It creates new value opportunities for brands and publishers that have extraordinarily high-quality demands and discerning opinions on what is offset replaceable."
Commercial availability of the new machines is expected in spring 2017. HP did not reveal pricing but said existing users of the original T-300 Series Inkjet Web Presses can upgrade their machines – including the HDNA technology, software, firmware, data and electronics – for around 20% of the original hardware price.
Earlier this year HP launched three other PageWide Web Presses; the 1.06m-wide full-colour T490 HD and the mono T490M HD as well as the 559mm-wide T240 HD.
