While commercial printing was the primary focus of Drupa 2008, the show has also become a major event for debuting new digital printing products. This overview provides details about key innovations in inkjet technology that were unveiled there.

The device includes a three-lamp UV-curing system with external chiller to keep temperatures down. The ink system features 5-l ink containers for each color, plus an addition 5-l reserve for each color that allows for automated refilling of the primary container. A Flush Brush maintenance system is built in to remove ink debris and residue from the nozzle plate and nozzle cores. The XLS has a special vacuum-table design with a clamping system to prevent both roll and rigid media from slipping or moving, and a head-positioning device keeps the nozzle plate of all heads 100% parallel to the printing plane. The machine is said to be ready for printing within 15 minutes of startup. It is driven by an Agfa Edition Wasatch RIP.
Based on Agfa’s Anapura M platform, the Anapurna Mv and Anapurna M4f support media with width of 62.2 in. The Mv handles both rigid and roll media and is a six-color machine (CMYKLcLm) with two extra heads for varnish, while the M4F is a flatbed for rigid stock that prints four colors (CMYK). Both offer 1440 x 720-dpi resolutions and a top print speed of 161 sq ft/hr. Like the Anapurna XLS, they also feature an Agfa Edition Wasatch RIP and support borderless and dual-board printing.
Durst Rho 320R UV and Rho SP 60
Two new machines were shown by Durst, including the Rho 320R and Rho SP 60. The 320R is an industrial roll-fed machine for media up to 10.5 ft wide and 2 mm thick. The CMYK printer—which has optional channels for white, Lc, Lm, spot-color, and varnish printing—offers a top print speed of 1400 sq ft/hr and a maximum resolution of 600 x 600 dpi with its Quadro Array printheads.
The system uses low-odor Rho Roll UV inks, an acrylic formulated for good color density and adhesion to a variety of coated and uncoated media. The 320R comes with 10-l ink tanks that can be refilled while the machine is operating. Inks for refilling are offered in 5-l containers.
