Hello PremiseOne,
I searched our knowledge base and couldn't find any specification on files size. I would suggest that you call into the support department @ 1-800-821-2797and request to speak with a software specialists.
What is the largest file size that can be exported from indesign to the igen 5 rip? For years this has been a major mystery for me. It's like if a file is too big it will not show up in the rip, or just spool for eternity.
