Re: Kodak NexPress vs. Xerox iGen3
I would lump three: NexPress, iGen3, and Indigo. Yes, they certainly are in a class of their own. Each are flag-ship products from: Kodak, Xerox, and HP, respectively.
What makes them similar to each other is often distinguishes by their price points, technology, and applications. They are all pricey to own and operate. They require a considerable amount of volume (like 100M+ to 1,000M) a month to justify ownership. The technology between each is very different from each other and different from mid-range digital presses. In a way, each one reinvents digital printing and they do it well. In fact, they all have started to turn heads and convince even printers that digital may be able to compete with conventional printing from the quality perspective on some applications. All three can produce POD, VDP, Trans-Promotional, and specialty products.
If you want to get *really* technical, you can read more about the technology differences on our new blog
http://lifeofprint.com/. Its a new blog dedicated to digital printing technology. We cover topics like this one all the time. All the bloggers, are technologists or press owners, like myself.
