C'est parce que c'est un "scan," un jpg ou une image insère dans un pdf. Tu peux essayer de changer le contraste dans ton e-reader, si le "setting" existe.

On peut essayer de faire un "OCR" du PDF original, mais ça sera difficile aux causes de tous les caractères mathématiques.

On peut aussie extraire les images du PDF et utiliser un logiciel comme Photoshop pour changer le contraste, mais c'est beaucoup de travail, et les résultats ne seront pas forcément efficaces.
