What a print proof taught us about brand systems
Crop marks, colour bars and registration targets exist so nothing drifts on press. A brand needs the same three things.

Every print job starts the same way: a proof. Before a single sheet runs, the printer pulls one copy covered in marks most people never see — crop marks at the corners, a strip of colour bars along the edge, and small crosshair targets that tell you whether the four plates are sitting on top of each other.
We started pinning proofs to the studio wall years ago, mostly because they are beautiful. Over time they became a way of thinking about brand systems.
1. Edges you can see
Crop marks show exactly where the design ends. A brand needs the same: a clear line around what it is, and what it is not. Most identities fail at the edges — the third-party slide deck, the hurried social post.
“A system is only as strong as its least careful use.”
2. A palette that is checked
Colour bars exist so the printer can measure ink, not guess it. We give every client the equivalent: tokens with names and numbers, contrast checked, written down once and used everywhere.

3. A mark that lines everything up
The registration target is the smallest thing on the sheet and the most important. It is why our logo ends in one. A brand needs a single element that everything else aligns to — usually type, sometimes a grid, rarely the logo itself.
