How bleed is checked
- If the PDF has a TrimBox, we measure how far the BleedBox (or the page) extends beyond it on each side.
- If there is no TrimBox, enter your finished size: a page equal to finished size + bleed counts as having bleed; a page equal to the finished size has none.
- Without a TrimBox and without a finished size we cannot know where the page will be cut, so bleed is shown as Not inspected.
We check the page geometry. Whether your artwork actually extends into the bleed area is not checked yet.
FAQ
- How much bleed do I need?
- Commonly 3 mm (or 0.125 in) on every trimmed edge. Book interiors printed on demand usually need it only on the top, bottom and outside edge. Always follow your printer's specification.
- What is the difference between trim and bleed?
- The trim size is the finished size after cutting. Bleed is extra artwork beyond the trim so no white edge appears if the cut moves slightly.
