Question
What's the best CMYK value for true black on printed materials?
Answer
The right black depends on how much of the page it covers. Small text and thin lines want a clean single-channel black so edges stay crisp, while large solid fills want a richer mix so the area does not look washed out.
| Use case | CMYK build | Why |
|---|---|---|
| Body text, thin lines | C0 M0 Y0 K100 | Stays sharp with no registration halo |
| Large fills, backgrounds | C50 M40 Y40 K100 | Deep, even black across big surfaces |
- Plain K100 on a large area can read as a flat, slightly gray black.
- Rich black on tiny text can blur if the ink layers shift even slightly.
- Keep total ink coverage reasonable so heavy areas dry properly and do not offset.
