If you have ever ordered business cards and noticed thin white edges along one or two sides after they were cut, you ran into the bleed problem. Here is what is happening and how to fix it.
What is bleed?
Commercial printers do not cut individual cards. They print 21 cards on a large sheet, then run a stack of those sheets through a blade. The blade is precise but not perfect: each cut can be off by up to 0.0625" (1/16").
If your color or background extends only to the trim line, a slightly-off cut leaves a sliver of unprinted paper showing. That sliver is what you see as a white edge.
The fix: 0.125" of bleed on every side
Design at the trim size + 0.125" extra on each side. So a 3.5" x 2" card becomes a 3.75" x 2.25" file. The extra is "bleed". Background color, photos, or patterns extend into that bleed area. When the cut happens, the blade lands in the bleed region, leaving clean color all the way to the new edge.
What to keep inside the safe zone
The opposite problem: if your text or logo is too close to the trim line, the cut might shave part of it off. Keep critical content at least 0.125" inside the trim line. This is the "safe area".
Quick reference for a 3.5" x 2" card
- File size: 3.75" x 2.25" (trim + 0.125" bleed all around)
- Trim line: at 3.5" x 2" centered in the file
- Safe area: 3.25" x 1.75" centered (text + logos inside this)
