It is important to read and to understand the guidelines when preparing your artwork. Every printer will have their own requirements. So do we. Don’t worry, we have simplified the procedure. It’s not going to be difficult.
The solid triangle on the front and reverse sides are meant to give you a reference point on how your front and reverse artworks will be rotated during production. (And yes, physically the front and reverse sides share the same corner) It is therefore essential that you prepare and place your artwork accordingly before uploading it to us.
