Delivering material to us is easy
If the job is small, less than 10MB, send an email:
to firstname.lastname@example.org (offset printing)
to email@example.com (digi printing)
or to a salesperson or repro staff.
Bigger jobs should always be sent via a cloud service. The easiest way is to use Wetransfer or pCloud.com, no software/client needs to be installed on your computer. Dropbox and OneDrive services requires an account owned by you.
