Abstract:
Disclosed is an uncoated facestock product having enhanced printability, holdout, and edge wick properties, which are attained through a combination of manufacturing techniques including increased refining of the furnish, sizing, increased hard nip calendering, and the use of extended nip calendering. The resulting uncoated facestock product has the following properties: a density between about 0.7 and 1.0 g/cc and/or an ash content of less than about 15% as measured by the 525° C. standard test method; and a finished surface having a Sheffield smoothness between about 50 and 150 Sheffield units and a Parker Print Surf roughness (PPS-10) less than about 5.0 microns.
