Kodak and Heidelberg created a joint project called Nexpress (www.nexpress.com) that is basically a high end laser printing system for medium-volume production runs - not enough to justify 4-color offset, but too many for Kinkos :)
It's supposed to do very high quality imaging, but I had a batch of prints done to evaluate the system (as a favor for a friend who's a design engineer at Xerox working on a competing machine!) My conclusion was that it's sort of OK, but nowhere near as good as a half-way decent inkjet printer. -- Mark Roberts Photography and writing www.robertstech.com
