Grayscale Printer Test
Print a grayscale test page to check tonal range, gradients, highlight detail, shadow detail, and print consistency.
Preview
Grayscale test sheet
What you see below is exactly what prints: seven labeled sections on a single page.
1 21-step grayscale wedge
0% to 100% in 5% steps. Adjacent tones should remain visibly distinguishable.
2 Highlight detail
0% to 10% in 1% steps. Reveals whether very light gray tones are being lost.
3 Shadow detail
90% to 100% in 1% steps. Reveals whether very dark gray tones are merging into black.
4 Continuous gradient
5 Uniform gray patches
Large patches. Check for uneven density or texture.
6 Fine gray lines
Thin gray lines at different weights. Check for broken, faded or uneven lines.
7 Neutral gray detail
Neutral gray blocks. Check whether gray appears neutral or has a visible color tint.
Recommended next test
Neighboring dark steps lose separation or crush into black.
Check shadow detail and density settings.
The smooth gradient breaks into visible bands.
Check tonal smoothness and driver settings.
Gray shows a red, green or blue cast.
A cast is worth checking for channel imbalance.
Thin gray lines break or vanish.
Broken lines are worth checking for blocked nozzles.

Grayscale vs Black & White Printer Test
- Black & White Printer Test checks pure black output, text sharpness, line quality and document printing.
- Grayscale Printer Test checks multiple gray levels, highlight/shadow detail, gradients, uniformity and neutral gray output.
Important:
Visual test only: Results are affected by printer technology, paper, print mode, driver settings, ink/toner, and color management. This test shows visible print behavior but cannot measure ink/toner levels or identify a specific failed component.
Compatibility
Printer compatibility
- Inkjet printers
- Laser printers
- Monochrome printers
- Color printers
Color printers may produce grayscale using black ink, color inks, or a combination depending on the printer and driver settings.
Process
How to use
Load clean white paper
Use plain paper without creases or previous prints.
Select the matching paper size
Pick the size loaded in your printer above.
Print at 100% / Actual Size
Avoid browser scaling for line and detail checks.
Inspect the printed patterns
Look for vanishing steps, banding, tint and broken lines.

What is Grayscale Printer Test?
A grayscale printer test prints multiple gray levels, highlight and shadow steps, a smooth gradient, uniform patches, fine lines and neutral gray on one page. It helps you visually check tonal separation, detail, banding, density and unwanted color tint.
FAQ
Grayscale test questions
How do I test grayscale output?
Print this page at 100% and check the wedge, gradient and both ends for distinct steps and smooth transitions.
What is a 21-step grayscale wedge?
Gray patches from 0% to 100% in 5% steps. Every step should stay visually distinct from its neighbors.
Why do light gray steps disappear?
Very light tones may be too close together to reproduce distinctly. Check your print quality, paper and driver settings.
Why do dark grays merge into black?
Very dark tones may be too close together to reproduce separately. Check your print quality, paper and driver settings.
Why does my gradient show bands?
Banding can be caused by print settings, paper, driver processing or uneven ink/toner output. Try the Print Quality Test next to compare gradients and other patterns.
Can I use this test on a monochrome printer?
Yes. Monochrome printers are ideal for this test since every section targets black-only output.
Does grayscale use color ink?
Many color printers can produce gray using a mixture of color inks. To test black-ink output separately, select a black-only or monochrome option if your printer provides one.
Do I need special paper?
No. Plain clean white paper matching the selected size is enough.
