If I'm understanding you correctly........are you saying you're wrapping vehicles with unlaminated UCJV prints? Would love to hear more about this, because I find it hard to believe. Which ink-set are you running?
Out of all our printers, the UCJV has the hardest and most scratch-resistant ink but I would never even fathom putting those unlaminated prints on a vehicle, let alone a wrap.
To the OP: I wouldn't consider the UCJV for wraps. It's a great machine but if you were to handle/work with UV and solvent/latex prints you would get why it's a bad idea. (Short story - UV ink sits on top of the vinyl and adds thickness and does not like to stretch like solvent or latex ink does) I personally don't have any experience with latex, and not sure I'll ever jump on that bandwagon, but I'll be looking at the Epson solvent printers next.
As already mentioned, make sure to check out the machines in person, see how they operate, and work with a dealer that will be a partner, not just a sales rep. They will be a valuable resource as you move forward.
Good luck with your search.
