What is EFI?
EFI are one of the bigger players in the RIP market. Many of their RIPS have their own profiling capabilities, so have supported the DTP-70 in the past.
What's not clear is if they have their own 64bit driver or they work with the unified driver.
Are you using Spectraview software.
Not sure why this would have any significance at all.
Please share your details if you have a solution.
That would certainly help, but so far no reply.
