How it works
Print at actual size
Download the test sheet PDF or open it in your browser’s print dialog. Print at 100% actual size.
Inspect and record
Print the sheet, then inspect the color patches, gray steps, lines and text. Record what you see.
Example
A4 color + grayscale → matching PDF and preview.
The 50 mm line should measure 50 mm at 100%.
Questions, Answered.
Does this measure ink levels?
No. It provides visible test patterns, not an ink-level or hardware diagnosis.
Will grayscale use only black ink?
The printer driver decides how RGB grays are reproduced. Grayscale selection does not guarantee black-ink-only printing.
What if the 50 mm line measures differently?
Check that the selected paper matches the loaded paper, print at 100% actual size, and turn off fit-to-page scaling. Driver and printer margins can affect output.
