What is Bleed in Printing?
If you’ve ever been asked to add bleed to your artwork, you’re not alone. It’s one of the most common questions people have when preparing files for print. Missing bleed is one of the most common artwork issues we see before a job goes to print.
The good news is that it’s a simple concept.
What is bleed?
Bleed is the part of your artwork that extends beyond the finished edge of the page.
It isn’t visible on the finished printed item because it’s trimmed away during the printing process.
The extra area simply allows the printer to trim each sheet accurately without leaving unwanted white borders.
Why is bleed needed?
Printed sheets are trimmed down to their final size after printing.
Although printing and cutting equipment is extremely accurate, tiny variations can occur during trimming.
If your artwork stops exactly at the edge of the finished page, even a very small movement could leave the unwanted white border.
Adding bleed prevents this from happening by extending the background colour or image beyond the trim line.
How much bleed do I need?
As a guide, for most commercial printing, 3mm bleed is the standard requirement.
If you’re unsure, always check the artwork specification before creating your document.
What happens if I don’t include bleed?
If artwork that should print to the edge of the page doesn’t include bleed, the artwork may need to be corrected before printing can begin.
Including bleed from the start helps avoid delays and ensures your finished print looks as intended.
Summary
Bleed is a small extension of your artwork beyond the finished page size. Although it’s trimmed away after printing, it plays an important role in helping printed materials achieve a clean, professional finish without unwanted white edges.
