What is ink coverage percentage?

Ink coverage is the proportion of the print area actually covered by ink. A solid flood fill is 100%; typical editorial text pages run 10–30%; photos and graphics often range 40–80%.

What ink film thickness should I use?

Offset lithography typically deposits 1–3 µm per color. Flexography runs 2–5 µm. Screen printing can be 5–30 µm. Use the spec from your press or ink supplier for the most accurate result.

Where do I find ink density?

Ink density (g/cm³) is listed on the ink supplier's technical data sheet. Most oil-based offset inks are 1.0–1.3 g/cm³; UV-curable inks are typically 1.1–1.5 g/cm³.

Does this account for all four CMYK channels?

The calculator estimates consumption for a single ink channel. For full-color CMYK printing, run the calculation once per color and sum the results, using the coverage percentage for each channel separately.

How accurate is this estimate?

The formula is a theoretical calculation. Real-world consumption will vary due to press makeready waste, ink misting, roller absorption, and substrate porosity. Add a 10–15% buffer for production planning.

Summary

Enter your print dimensions, coverage percentage, ink density, and copy count to get total ink consumption in grams and milliliters.

How it works

Enter the width and height of the print area in millimeters or inches.
Set the ink coverage percentage — the fraction of the print area that is actually covered with ink.
Enter the ink film thickness in microns (typical offset lithography: 1–3 µm; screen printing: 5–30 µm).
Provide the ink density in g/cm³ (most offset inks: 1.0–1.3 g/cm³; UV inks: 1.1–1.5 g/cm³).
Enter the number of copies in the print run.
The calculator multiplies area × coverage × film thickness × density × copies and displays total ink weight in grams and volume in milliliters.

Use cases

Estimate ink costs before quoting a commercial print job.
Compare ink consumption between different coverage designs.
Plan ink stock levels for a production run.
Reduce over-ordering and minimize leftover ink waste.
Benchmark ink usage across different substrates and ink types.
Verify ink consumption figures from press operators.
