We investigated the effects of the enzyme treatment of fiber for printability of coated paper. The results could summarized as follows, 1. The samples with enzyme treatment (average 87.8%) have higher ink gloss than the blank (85.6%). Printed density showed same trends with the ink gloss. However, the β-Glucosidase treated sample showed the lowest printed density (2.14 %) due to the lowest thickness of the ink layer, which is influenced by coated weight and surface smoothness. 2. The samples whose base paper was Xylanase and β-Glucosidase treated showed higher surface strength (4.2% and 4.0%, respectively) than the blank while the samples with the Hernicellulase and β-Glucuronidase treatment showed lower surface strength (3.2%and 3.7%, respectively) due to the influence of air permeability. 3. Hemicellulase and β-Glucuronidase treated base paper, which have relatively low air permeability, showed better ink repellence (4.3 and 4.4 %, respectively) than the blank (3.8 %). 4. The blank and the Xylanase treated base paper showed high set-off, which is the last category of printability.
