Can I upload a new file to replace only part of my order (like just the front page)?

Yes. You can replace just one part of a job, such as a single side, without redoing the whole design. The trick is telling the team exactly what needs a new proof.

• Upload the updated file for the portion you want to change.
• In the comments, note precisely what to re-proof, for example new proof needed for front page only, back looks good.
• The rest of your design stays as it is.
• You will receive an updated proof reflecting only the changed portion.
