From the date when we receive the order and (if applicable) deposit, we normally send the proofs within 2-3 business days. Once the proofs have been approved and the balance has been paid, you can expect to receive the finished artwork within a further 2 business days.
Of course these timescales do not include the time you take in considering the proofs; this is not within our control.
Artwork is sent by e-mail, normally in PDF format. If you have only asked for drawings without any typesetting, we may suggest using JPEG format instead, since this makes it easier to introduce images into other documents and resize them if necessary.
