We recommend an Online PDF Proof for all orders. When your files are uploaded, our prepress team will look over your files to ensure everything looks suitable for printing and upload a PDF proof to your account (a notification email will also be sent) for approval before production.
If the prepress team does notice any issues, they will add a warning (Suggestion from Prepress) to your order status page. Whilst our prepress department will do their best to let you know about all issues or potential issues – it is the customer's responsibility to submit files that are ready for print.
An Online PDF Proof may have an additional cost for certain products. Please see: What to check on my proof for details of what to check when you receive your proof.
