In practice

3 mm bleed:
what happens at the trim.

The same piece, the same trim. Once without bleed and once with 3 mm bleed. The difference is decided at the edge.

The trim, step by step

A few tenths of a millimetre make the difference.

01

The sheet is printed larger

Every piece is printed on a sheet larger than its finished size and trimmed after printing. The crop marks show exactly where.

02

Every trim has a tolerance

Trimming is accurate to a fraction of a millimetre. That small, normal tolerance exists in every trim, at every printer.

03

Without bleed

When the colour stops exactly on the trim line, the slightest deviation leaves a white line along the edge.

04

With 3 mm bleed

When the colour continues 3 mm beyond the trim line, the same deviation falls within the colour. The edge stays clean.

What your file needs

  • 3 mm bleed. Backgrounds and images that run to the edge continue 3 mm beyond the trim line, on every side.
  • Safety margin. Text and logos stay at least 4 mm inside the trim line.
  • Correct export. The PDF is exported with bleed and crop marks.

Less waste, from the start

A file that is right from the start needs no corrections and no reprint. Less paper, less energy, less waste: sustainability starts with file preparation.
