which is better?
iGen3/4 or NexPress
Having worked for both company in development and in the field I seen both presses work at different levels. I helped launch the iGen 3 when it was introduced. I also installed NexPresses worldwide.
The questions presented in the topic are interesting. Given what I know about both machines the iGen 3 and 4 out performes the NexPress built at its time from the 2100 to the present. The iGen has a greater range of media, larger sheet size and duty cycle. The workflow to the iGen without extta applications is more diverse. This is not to say that the NexPress is not a good press it however is not on the same level as an iGen.
Dementional printing is an interesting gimick. However the duty cycle of the press and workflow is why you purchase a press. If the press is not able to print it is costing you money, even worse if the print is of poor quality and not sellable its costing you. The iGen 4 has internal color calibrations to insure that the color is correct sheet to sheet, inboard to outboard and day to day. The NexPress does not have this ability. The daily process to get a NexPress running for production can take 1 hour (not including developer changes, and replacing the web), the iGen 4 you never do a developer change and the photoreceptor is a 10 min operation.
Workflow the second key to the equaltion. No-one and argue that Kodak has a good workflow with Printergy. But this workflow is costly, and designed for an offset world. If you purchase the digital package it intergrates with the NexPress as well as the iGen. Xerox brings to the table years of digital printing. The workflow tools are simple and easy Xerox has several ways to automate workflows to anyone environment.
Okay what about variable data! VI printing from the NexPress is the open standard of VDX, this is a nice standard xml data with pdf content. It is an open standard which is great for the consumer. Xerox has VIPP, VPS, PS/PPML in its list, most of these are not open standards but are the file formats of the dfe you pick. Xerox offers more choices, NexPress offers you an open standard but this format is only consumed by NexPress. Because of these facts Xerox comes out ahead in offreings. Also whichever application that you pick to generate the VPS you would have to pay extra for the driver and that same applications most likely could generat the file format for the iGen.

Enough what about the environment?
The iGen is a green machine and Rohs complient.
the iGen functions very well under bad conditions, high temps and low humidity. The NexPress shuts down if the temperature can not be cntrolled.

What about the installation?
The iGen only requires electrical conections, a heat vent and a water drain, as well as space.
The NexPress, electrical, water supply, drain, vent, and compressed air. Here is the only true advantage its smaller.
I have seen hard water shut down a NexPress for a week. Poor compressed air quaility cause image defects (the webs tension is controlled by air pressure).

In the end the iGen is a better press, for the cost the NexPress isn't bad butthe two are not in the same league. The iGen is better.
