This study focuses on the effect of different types of precalendering on coated woodfree paper for surface and printing properties as well as coat weight distribution and binder migration.

Precalendering enhanced the gloss and reduced the roughness of the coated paper at all coat weights. In the case of post-calendered papers, any differential effect achieved through various types of precalendering was recovered during post calendering. The final porosity values of precalendered and uncalendered sheets were more dependent on the coat weight at the high coat weights (10-18 g/m2 ). At low coat weights the type of precalendering influences the final porosity values.

Precalendering also increased the delta gloss and print density- values of the final product. This was observed for the papers that had been subjected to the post-calendering, as well as for those that were not. In the case of print density the type of calendering did not have any specific influence on the final print density values. The data also indicate that the surf ace latex distribution was not dependent on the type of precalendering and calendering intensity. The latex distribution is found to be more uniform at higher surf ace latex content.
