Abstract: Disclosed is a process for preparing a paper web. The paper web is prepared from a low-grade furnish, which contains low-grade pulps, such as recycled pulp and/or groundwood pulp, and which, in one preferred embodiment, is a newsprint furnish. In accordance with the disclosed process, a pre-flocculated filler is added to the furnish prior to forming the paper web from the furnish. Filler will be retained in the web, and retention of undesired components of the furnish in the web will be reduced as compared with newsprint in which a filler is incorporated via conventional processes. Another embodiment contemplates the incorporation of a pre-flocculated coated broke slurry into a paper furnish prior to paper formation. The paper web formed via the process of the invention will have improved properties as a result of the incorporation of the pre-flocculated filler or treated broke into the web.
