What is print bleed — and why does my printed flyer have white edges?

Every time I run a Canva workshop, one of the first things I ask the room is: does anyone know what bleed is when it comes to printing?

Most of the time, one person puts their hand up. Maybe. And the rest of the room does that face — the slight squint, the small nod — the one that says I've definitely heard that word before and I'm going to keep quiet and hope nobody asks me.

If that's you, this one's for you.

So what actually is bleed?

When you send a file to a printer — a flyer, a business card, a brochure — and your design goes right to the edge of the page, the printer needs a little extra artwork beyond that edge to work with.

Here's why. Commercial printers don't print one piece at a time. They print a stack of them on a larger sheet and then cut them all down to size in one go. And cutting — even with a machine — is never perfectly exact. There's always a tiny amount of movement, a fraction of a millimetre, one way or the other.

If your artwork stops exactly at the edge of where you want the page to end, and the cut lands even slightly outside that line — you get a thin strip of plain white paper showing. That's it. That's the white edge. Not a printing error. Not bad luck. Just physics and the fact that nobody told the file to account for it.

Bleed is the fix. It's a small amount of extra artwork — usually 3mm — that extends beyond where the cut will happen. The printer cuts through that overlap, and the result goes right to the edge cleanly, the way it was supposed to look.

So how does that happen in a file?

If you're designing in something like Canva, there's a setting you can turn on called print bleed — you'll find it under File > View settings > Show print bleed. When you turn it on, you'll see a faint guide line showing you where the cut will happen, and the area beyond it that you need to fill.

The key thing is making sure your background colour or image actually extends out to that outer edge — not just to the cut line. If it stops at the cut line, you're back to the white edge problem.

Canva also has a bleed option when you export. When you're downloading your file for print, choose PDF Print as the file type, and tick the box for Crop marks and bleed. That tells the file to include that 3mm extension when it goes to the printer.

If you're working in professional design software like Adobe Illustrator or InDesign, bleed is set up when you create the document — it's one of the first things a graphic designer does before they start. It becomes automatic. If you're using those programs and you weren't already doing this, now you know.

Why does this matter ?

Because by the time you notice the white edges, the job is already printed. And reprinting costs real money — for the paper, the ink, the time, and often the delivery too.

The fix takes about thirty seconds when you know what you're doing. It's the kind of thing that feels technical until someone explains it plainly, and then it seems obvious.

This is why it really does help to have someone in your corner who understands print — not someone who wants to take the work off you, but someone who can answer the quick question before you hit send.

A lot of print mistakes aren't about bad design. They're about not knowing what the printer actually needs from the file.

So yes, you can absolutely do your own artwork. But doing it well means knowing a few things the software doesn't tell you by default. Bleed is just one of them.
