Common mistakes to avoid
- Filigrane trop opaque : rend le texte difficile à lire.
- Filigrane petit et discret : facile à supprimer en quelques clics.
- Oublier d'appliquer le filigrane à toutes les sections.
Pro tips
- Utilisez un filigrane semi-transparent (30 à 50 % d'opacité) en diagonale.
- "BROUILLON", "CONFIDENTIEL", "NE PAS DISTRIBUER" sont les filigranes les plus courants.
- Pour une protection robuste, exportez en PDF avec filigrane intégré et non modifiable.
