Précautions pour la numérisation à haute
résolution
Veuillez noter que la taille des fichiers augmente de façon exponentielle avec la
résolution, lors d’une numérisation en mode couleur. La numérisation à haute
résolution peut demander plus de temps pour la numérisation et le traitement
de l’image. Nous vous recommandons de ne pas augmenter la résolution au-
delà des exigences minimales pour numérise en mode couleur.
Estimation de la taille du fichier pour la numérisation d’un
document de taille “Letter” en couleur.
- 100 ppp 3 Mo
- 300 ppp 26 Mo
- 600 ppp 105 Mo
- 1200 ppp 418 Mo
Directives pour le choix d’une résolution
Pour le transfert de fichiers vers un site internet ou pour une visualisation sur
le moniteur d’un ordinateur, choisissez 72 ppp.
Pour la numérisation de photos imprimées ou d’extraits de magazines,
choisissez entre 150 et 300 ppp.
Pour imprimer sur une imprimante à jet d’encre, choisissez une résolution
correspondant à environ la moitié de la résolution de l’imprimante (180 ppp,
360 ppp, 720 ppp).
La résolution de 1200 ppp est efficace pour la numérisation de documents très
petits qui doivent être agrandis pour l’impression (par exemple,
l’agrandissement d’une image 3,5 x 5 pouces à la taille Letter).
