I-Newsprint inesisindo esiphansi, ubumhlophe obuphansi kanye nenqwaba enhle, ngokuqhubeka kobuchwepheshe bokukhiqiza, i-newsprint isetshenziselwa ukuphrinta imibala kancane kancane;iphepha eliboshwe imbozwe phezu kwephepha lesisekelo, elinokushelela okuphezulu, ukumhlophe okuphezulu nokucwebezela okuphezulu, umbala wokuphrinta ugqamile, izingqimba zicacile, futhi ngokuvamile zisetshenziselwa ukuphrinta imikhiqizo emihle; ibhodi elimhlophe eliboshwe liwukumboza phezu kwebhodi elimhlophe, elinobushelelezi obuhle, i-gloss enhle nokuqina okuphezulu, futhi ivame ukusetshenziselwa ukupakishwa komkhiqizo. Kunomehluko ezintweni ezibonakalayo njengokushelela, ukucwebezela, ukumuncwa kukayinki, ubumhlophe, kanye nenqwaba yalawa maphepha amathathu.
Ngemva kokuhlolwa kokuhlolwa, i-newsprint inenqwaba engcono kakhulu, ubumhlophe obuphansi kakhulu, ubuhwaba obuphakeme be-PPS, isicwebezelisi esibi kakhulu, nokufiphala okuphansi kakhulu; iiphepha lobuciko inokuqina okuphezulu kakhulu, ubumhlophe obuphakeme kakhulu, ubulukhuni be-PPS obuphansi kakhulu, isicwebezelisi esihle kakhulu, nokungafihli. Phezulu; Iphepha elimhlophe eliboshwe linobuningi obungcono, ubumhlophe obuphezulu, ubuhhadlahhadla be-PPS obuphansi kanye nokucwebezela okungcono. I-pulp yokukhiqizwa kwe-newsprint i-pulp yemishini, egcina i-lignin ngangokunokwenzeka phakathi nenqubo yokukhiqiza, enobumhlophe obuphansi kanye nenqwaba enhle, kodwa i-newsprint inesisindo esiyisisekelo esiphansi kanye nokungabonakali okuphansi uma kuqhathaniswa nephepha elimboziwe. Iphepha eliboshwe kanye nebhodi elimhlophe lifakwe ngopende ebusweni bephepha lesisekelo, futhi i-pigment ekumbozeni igcwalisa ukucindezeleka okungalingani ebusweni bephepha. Ngemuva kwe-calendering nokuqeda, izinhlayiya ze-pigment zihlelwe ngendlela yokuqondisa, okunciphisa ukuqina kwephepha eliboshwe kanye nebhodi elimhlophe le-PPS futhi kwandise ukushelela. Njengoba isicwebezelisi sincike ngokuyinhloko ekusheleleni kwephepha lephepha, isicwebezelisi sephepha (ibhodi) silandelana ngendlela ephambene nobulukhuni be-PPS, okungukuthi, iphepha elimboziwe > amakhadibhodi amhlophe > i-newsprint.
I-gloss yokuphrinta ithintwa ubushelelezi bendawo yephepha kanye nokusebenza kokumuncwa kweyinki. Ukufakwa kwephepha kungathuthukisa kakhulu isicwebezelisi sokuphrinta sephepha. Ingaphezulu lephepha lezindaba limahhadlahhadla futhi limunca kahle uyinki. I-gloss yokuphrinta ingama-17.6% kuphela, kanye nokushelela kwe-surfaceiphepha lobuciko elihlanganisiwe iphezulu. , Ukumuncwa kweyinki kumaphakathi, isicwebezelisi sokuphrinta singama-86.6%, futhi isicwebezelisi sokuphrinta sebhodi elimhlophe eliboshwe ngu-82.4%.
Amaphepha anomunca uyinki omaphakathi, kanye nesicwebezelisi esiphezulu, akhiqiza imibala egcwele kakhulu. Iphepha le-matte elimunca ngo-100% lizophrinta imibala empofu kakhulu. Ukusebenza kahle kwephepha lephepha elinandisiwe kuphezulu kakhulu, kulandelwa ibhodi elimhlophe elinamekwe, kanti ukusebenza kahle kwephepha le-newsprint kuphansi kakhulu. Ukunciphisa ngokufanelekile ukumuncwa kukayinki we-newsprint kanye nokunciphisa ubulukhuni be-PPS bombhalo wezindaba kuzosiza ukuthuthukisa ukusebenza kahle kwephepha.
