Yes that is a good choice for a printer, but without a front end it's not a proofer. Likely the best options for that will be from GMG, CGS-ORIS or EFI, depending on your needs.
we use a 4900 with a fiery XF front end. We have had oris in the past- like both.
Not to hijack the thread, but I am currently using Oris and find the interface to be super clunky and over complicated. I've used EFI in the past and found it much more sleek and intuitive. What are your thoughts?
