Send production files with the context we need.
File transfer works best when the upload includes the project name, company, contact details, account manager, quote number, due date, and a short note about what the files are for. That context helps the team match the artwork to the right estimate, proof, reorder, or live job.
For print-ready artwork, PDF files are usually the best starting point. If you are sending packaged InDesign, Illustrator, Photoshop, image, font, or support files, compress the full set into a single archive when possible.
