If you've ever ordered print from a professional printer or opened a design template for buttons or badges, you've probably seen the word bleed. It sounds technical, but once you understand it, it's one of those things you can never un-see — and your prints will be much better for it.
The Simple Explanation
When something is printed and then cut or assembled, the cutting isn't perfectly precise. There's always a tiny margin of error — maybe half a millimeter, maybe a full millimeter. If your design stops exactly at the cut line, that small error can reveal a sliver of white paper at the edge.
Bleed is the buffer zone. You extend your background color or image slightly beyond where the cut happens. Even if the cut is slightly off, there's still color right to the edge.
Bleed in Pin Button Making
For pin buttons, the situation is a bit different from flat printing. The button is assembled by:
- Printing a disk slightly larger than the button face
- Placing the printed disk onto the button shell
- Folding the outer edge down and crimping it under the back
The folded part disappears inside the button. So your design needs to extend into that fold area — that extension is the bleed.
How much bleed for buttons?
3 mm is the standard. For a 25 mm button, your artwork circle should be 31 mm in diameter. The extra 3 mm on each side folds around the edge.
The Three Zones
Think of a button design as three concentric circles:
- Bleed circle (outer): The full artwork area. Everything you draw here will be printed, but the edge will be folded.
- Trim/safe circle (middle): The final visible button face. This is where the front of the button ends.
- Safe zone (inner): Where important content — text, faces, logos — should stay. Leave a 2–3 mm gap between the trim line and anything you need to be clearly visible.
What Happens If You Skip Bleed?
- White ring at the edge — the most common problem. The paper background shows through at the fold.
- Off-center design — if the cut is slightly off and there's no bleed, the whole design shifts visibly.
- Harsh lines at the edge — a design that ends abruptly at the trim looks cheap and unfinished.
What Happens If You Skip the Safe Zone?
- Text gets cut off — words or letters near the edge get folded away and aren't readable.
- Faces or key elements are partially hidden — especially on small buttons, anything near the edge can disappear into the fold.
How Button Print Maker Handles This
You don't have to measure circles manually. Button Print Maker shows you exactly where the bleed edge is and where the visible face ends. When you upload an image:
- The image fills the full bleed circle automatically
- Dotted trim lines show where the button face is
- You can drag and zoom your image to make sure key content is in the visible area
Just open the designer at /designer, choose your button size, and everything is pre-calculated.
Quick Reference
| Button size | Visible face | With 3 mm bleed |
|---|---|---|
| 20 mm | 20 mm | 26 mm |
| 25 mm | 25 mm | 31 mm |
| 32 mm | 32 mm | 38 mm |
| 58 mm | 58 mm | 64 mm |
Summary
Bleed isn't complicated — it's just a small buffer that prevents white edges and alignment problems. For buttons, it's the part of your design that gets folded around the shell. Keep it at 3 mm, keep important content inside the safe zone, and you'll get clean results every time.
