Large Format Printer Test Page
Wide printers fail across the width rather than down the page. This sheet carries the pattern from edge to edge so a banding fault on one pass cannot hide in the middle of the sheet.
Set scaling to 100%. Choose Actual Size in the print dialog, never Fit to page — scaling distorts every measurement on this sheet. The Download PDF button hands you that same sheet as a ready-made file, so there is no scaling decision to get wrong.
How to print the Large Format Printer Test Page
- Set the media in the driver to the actual roll width — not the closest default.
- Load the roll square, with the guides against the edges rather than tight against the media.
- Choose the quality mode you use for real work, since head height and pass count change with it.
- Set scaling to Actual Size or 100%.
- Print the full width in one pass rather than fitting it to a narrower area.
- Judge it under even light, standing square to the sheet rather than at an angle.
Reading the result
| The pattern is uniform across the full width | Every head or pen is firing together. Anything else you can see is media, profile or feed rather than coverage. |
| One band differs from its neighbours | A single head or nozzle bank is underperforming. On most plotters the heads are individually replaceable, which makes this the cheapest fault to confirm. |
| Faults begin part-way across the roll | Media is not feeding flat, or the roll is loaded off-square. Re-load it and check the guides before touching any hardware. |
| Colour shifts between the left and right edges | Either the light where you are judging it is uneven, or the profile does not cover the full width. Move to even light first — a surprising number of colour faults are lighting. |
| The sheet is correct but the crop is wrong | The driver is fitting a wide job onto a narrower media size. Set the media to the actual roll width and scaling to 100%, then reprint. |

- Banding printer test page — Solid bars hide banding. Gradients expose it. This page prints both, side by side, for each channel.
- DPI chart guide printer test page — A DPI chart does not print a number. It prints a set of lines that get closer together until they merge, and the point at which they stop being distinguishable is your result.
- Paper sizes printer test page — A test page only measures your printer if the sheet matches the paper in the tray. Choose the size you actually load and the geometry on the page stays true.
Frequently asked questions
Why is a large format test page different from an A4 one?
Because the failure mode moves. On a narrow sheet a head problem shows as a gap down the page; on a wide one it shows as a band across the width, and it can be invisible if the pattern only occupies the middle. This sheet deliberately runs the pattern across the full width so that a single underperforming head cannot hide in the centre of the sheet.
What causes banding on a plotter?
Three things in practice: a nozzle that is not firing on one pass, a head-height setting that does not match the media, or a feed that is slipping between passes. The pitch of the repeat is the quickest discriminator — a regular pitch that matches the pass spacing points at the head, an irregular one points at the media.
Should I print this on roll media or cut sheets?
On the media you actually use. A roll tells you about feed and tension across a long run, which cut sheets cannot. If you only ever print cut sheets, test on those instead — the reading transfers to the stock you printed, not to the stock you own.
Is a high resolution always better for wide prints?
Not beyond the point where ink spread takes over. Wide printers are usually run at a resolution chosen for viewing distance, and pushing it higher increases banding risk as well as ink use. Test at the resolution you will actually run and read the result there.
How often should I run a wide-format test?
After a head change, after a long idle period, and whenever a production run matters. Wide-format heads are expensive and consumables are significant, so a single sheet before a long print is the cheapest insurance available.
