Print ready files: PDFs won't convert (keep having an error)
The file size issue is likely a result of the print ready file expanding. If you compresses the file at all before uploading, it may be getting un-compressed when we prep it for print. Then, when the file sends to our printers it takes so long for them to download it times out, resulting in the error.
That said, 200mb isn't
big, so I'm surprised you're getting that error. I would start with ensuring all your images are 300dpi resolution and that the entire document is flattened. If you continue to work with our support team, they can always offer additional advice and assistance.
