Bleed & Borderless Printer Test Page

True borderless printing — where ink coverage reaches every physical edge of the paper — is mechanically difficult. The printhead must print past the paper’s edges, which means ink sprays onto the internal platen (the flat surface behind the paper). To manage this, most consumer inkjets enlarge the image by approximately 3–5% and shift it so the edges extend beyond the paper boundaries. The result looks borderless, but you’re actually losing a thin strip of your image on all four sides.

Some printers let you control how much enlargement is applied. Canon calls this “Borderless Expansion Amount”; Epson calls it “Expansion”; HP generally doesn’t expose the setting. Reducing the expansion preserves more of your image but increases the risk of a thin white line along one or more edges if the paper doesn’t align perfectly. This test page’s corner markers help you find the right balance: if corners are clipped, reduce the expansion. If white lines appear at the edges, increase it.

Laser printers rarely support true borderless printing because the fuser mechanism requires a margin to grip the paper. Some high-end lasers offer a “near-borderless” mode that reduces margins to 2–3mm, but that’s as close as they get. If you need true edge-to-edge printing on a laser, print on oversized paper and trim to size — which is how professional print shops achieve bleed. Borderless printing becomes even more complex with duplex (double-sided) printing, where front-and-back edge alignment must also be precise.

If your borderless prints consistently show a thin white strip along one edge — usually the trailing edge (the last edge to pass under the printhead) — the printer’s borderless expansion calibration is slightly off. This is extremely common and is rarely a sign of a broken printer.

Try these fixes in order: First, increase the borderless expansion amount if your driver exposes this setting. Second, verify the paper is fully seated in the tray against the guides — even 1mm of paper misposition changes where the ink lands relative to the edge. Third, try a different paper brand; paper thickness and stiffness affect how precisely the sheet feeds, and some paper brands consistently feed more accurately than others in a given printer.

For work going to a commercial print shop — business cards, flyers, posters — you don’t need your home printer to achieve borderless. Print with standard margins and add crop marks instead. The shop’s cutter trims to the bleed line. The Paper Size Guide covers standard bleed amounts for common print shop formats.
