摘要：
A method of manufacturing a newsprint paper for offset printing, includes: selecting a filler or fillers having an average grain size of 0.5 to 5 μm and a zeta potential of 0 mV or above; providing a pulp slurry for making a base paper; adding the filler or fillers to the pulp slurry in an amount of more than 15 percent by weight but less than 40 percent by weight as ash relative to the dry weight of the base paper; and subjecting the resultant slurry to a papermaking machine to obtain the base paper.
