Frequently asked questions
- How many colors can I use?
- Depends on your palette and band settings. FlatStack maps image colors to printable layers similar to other multicolor modes.
- Will text stay readable?
- High-contrast vector-style art works best. Very small type may need thicker plates or fewer colors.
