CA 2114335

The filler in the paper is synthetic silica, which can be precipitated, spray-dried and ground. Paper containing this type of filler and particularly newsprint paper is well suited to four colour offset printing. The show-through of the printing is reduced.

Cette invention concerne un papier renfermant de la silice synthétique qui se prête à la précipitation, au séchage par pulvérisation et au broyage. Les papiers renfermant ce type de charge, en particulier le papier journal, convient très bien à l'impression en quadrichromie sur presse offset. La transparence du papier ainsi traité est réduite.
