Color output test: a controlled physical comparison
Use it when prints look tinted, dull, oversaturated, posterized, or different after replacing a cartridge, changing paper, or switching quality modes.
01 / INSPECT
What to inspect on paper
- Cyan, magenta, yellow, and black fields are solid and even.
- Gradients transition continuously without abrupt bands or missing tones.
- Neutral balance patches remain gray instead of leaning red, green, blue, cyan, magenta, or yellow.
- Colored registration marks converge on the black center.
02 / HEALTHY OUTPUT
What a clean result looks like
- Primary and secondary colors are clearly separated.
- Light tints remain visible and dark mixed colors retain detail.
- No channel drops out across the tint ramps.
03 / LIMITS
What the result does not prove
- A browser sheet is a reference, not an ICC-certified proof.
- Paper coating and driver media type can change saturation and ink limits.
- One missing process color can alter several mixed patches at once.
HONEST BROWSER BOUNDARY
The sheet is the diagnostic instrument.
I/O Checkup prepares the controlled pattern and opens the browser print dialog. A webpage cannot reliably read your printer model, queue, driver faults, ink or toner level, maintenance state, or mechanical condition. Diagnose those systems with the printer manufacturer’s utility after the physical sheet shows a repeatable symptom.
