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.

Other features of the printer include UV lamps with dichroic reflectors. The lamps are adjustable in steps and can be set to cure the inks even on temperature-sensitive media. A magnetic linear-drive system ensures accurate machine movement. The roll support at the loading side of the device allows for the use of pneumatic 3-in.-core or optional 6-in.-core axles. It holds media with an outside diameter of up to 17.7 in. and a weight up to 661 lb.
The printer includes user-friendly LINUX operating software with management functions (ink usage/job, total ink consumption, print-time/job etc) and an interface to external order check software. An external Caldera RIP+ server is included with the system.
Durst’s Rho SP 60 is an industrial inkjet printer for decorating wood panels up to 25 in. wide. It allows the decoration of both flat and uneven panels with a variety of patterns produced with CMYK UV inks. With patented Durst Random De-sign Printing Technology, the machine can create a virtually endless variety of different grain and pattern designs. The single-pass printer operates at a top linear speed of 100 ft/min. (12,400 sq ft/hr), and in addition to wood, it can be used on paper, plastics, and more.
EFI VUTEk DS Series
EFI Vutek showed a demo version of its DS Series printer, which is expected to be available in 2009. With the reported ability to print saleable graphics at speeds up to 6000 sq ft/hr at 600 dpi, the machine is being targeted specifically at screen-printing shops, hence its “digital screen” (DS) designation.
A great deal of the machine’s speed stems from its configuration, which comprises a fixed-array printhead and a shuttling vacuum bed that supports substrates up to 63 x 96 in. and 2 in. thick. The bed consists of a user-controllable, zoned vacuum table capable of handling standard single graphics or multiple panels of different sizes. An optional advanced media-handling system is available to automate loading and unloading, and EFI Vutek says the system can add 100% to the printer’s productivity.
