pcc that is produced using chemical methods such as the carbonic acid gas method and carbonate solution method is preferred in particular the type of pcc produced on site in the papermaking plant and added to the paper material as slurry is more preferable because it contains no dispersant and whose zeta potential is 0 mv or above as for the papermaking machine used to produce the newsprint paper for offset printing as proposed by the present invention a gap former papermaking machine hybrid former papermaking machine or on top former papermaking machine each of which has a dewatering mechanism on both sides is desirable however the choice is not limited to these machines as for the pulp material of the newsprint paper for offset printing as proposed by the present invention there are no limitations and any pulps commonly used as paper material such as ground pulp gp thermomechanical pulp tmp chemi thermomechanical pulp ctmp deinked pulp dip and softwood kraft pulp nkp can be used the smoothness friction coefficient and other properties of the obtained newsprint paper for offset printing are deemed sufficient as long as they are equivalent to those of a regular newspaper used for offset printing the clear coat used in the present invention can be selected from starch oxidized starch esterized starch etherized starch cationic starch enzyme modified starch aldehyde starch hydroxyethyl etherized starch and other modified starches carboxymethyl cellulose hydroxyethyl.
