We've had an Illumina GS installed since end of last year, it's basically been used for non-variable envelope jobs. (I know they advertise that it can do sheets up to 47" or something but that wasn't ever our intended use.) Here are some observations:
The Good:
•*Handles most stocks well, including some metallics & translucent material
•*Speed is decent, we've done quantities up to 2500 although it requires near constant attention to load/unload the stock
•*Color fidelity is tolerable, within a run it doesn't stray once you are on target
•*Overall operation is simple enough, and it's a quiet, compact unit that can occupy office space without being too bothersome
The Not So Good:
• We've had some scumming & marking that Xanté has some weird workarounds for, taping pieces inside the press & bending metal brackets. Xanté says they are constantly tweaking the setup to address these issues, but it can take some trial & error in the mean time
•*Variable jobs can only be sent as full record lists, if you lose an entry or several pieces you have to isolate them in prepress & resend just those records.
•*There's no "true" Pantone matching. It converts PMS colors to its own numbered system and you can make adjustments from there, and at least you can tell the RIP always remap certain builds once you have them dialed in.
•*Every size of envelope needs its own Preset in InDesign, not sure about Quark or others. So you can conceivably have a few dozen presets in your Print dialogue
• Installing the Xanté driver on our Mac workstations (running 10.6.8) completely ruined our ability to send to another device. The Xanté HAS TO have rosetta installed on Macs according to the tech that put our unit in, so if you're on an OS that’s unable to have Rosetta, not sure how you print to the device. Unsure about Windows machines.
That's mostly it, we use their consumables purchased from a local reseller. We're not doing enough volume to warrant trying 3rd party materials or risk voiding the service contract. Any questions, ask away & I'll try to answer!
