Crack! Pop! (That's the sound of my knuckles cracking as I prepare to type)
I have an Ilumina (not the Envelope model) and it does fantastic on envelopes- self seal, linen, laid, even a 9x12 photo on a 10x13 envelope. In another thread, I think someone asked about addressing on preprinted UV coated post cards. I do! And if I had the Envelope Press (Xante calls it the media feeder) it would make those post cards a hell of a lot easier! I agree with Corey, 5000 would probably be pushing it but if it's got variable info, there is no limit. They advertise 1.5 cents per impression but I think 2-3 cents is more realistic because anything heavier than 20lb bond is harder on your drums. So, 5000 full color envelopes at .03 cents would cost $175 + machine + labor + envelopes. And if they are VDP you can tack on a premium and other set-up charges. I don't know what your market is or your overhead, but Vistaprint wants to charge $719.99 for 5000. I know I can beat that AND keep a good margin.
Speaking of costs, Xante is still holding the price at $14,999. Wait till the end of the month for some bargaining leverage. Try contacting this dealer-
Xante Laser Printers - Xante Color Printers - The Richardson Company
His name is George and is very nice and helpful. I buy all my consumables from him and he offers free tech support when you buy from him. If it wasn't for him, I would have thrown my Ilumina out the damn window! AND he saves me money on the consumables. Trust me when I say this- he is not a typical dealer/sales rep. He won't paint a rosy picture and tell you the Ilumina makes sandwiches too. Don't get me wrong, he does stand behind his products.
As for color control, the Ilumina does very well at automatic calibration. As long as you print from a smart program (not Reader) and have your color profiles set, you'll have few problems. And keep in mind, some PMS colors are harder to build than others. But if that is not enough, Xante has their OpenRIP Symphony. I have no experience with it but I have heard a lot of good about it. In fact, I'm considering purchasing it along with a new machine. Damn, I sound like I work for Xante...
In conclusion, I do not work for or represent Xante. Ondemandbindery, If you'd like, it would be my pleasure to talk to you and pass on my experiences with the Ilumina I've had for three years.
I am tired of typing,
