Iphepha le-Kraft njengento eqhelekileyo kwishishini lokuprinta kunye nokupakisha, ngoko uyazi indlela yokusebenzisaiphepha le-kraftngokuchanekileyo?
Ukusetyenziswa kwephepha le-kraft
Kwishishini lokuprinta kunye nokupakisha, i-kraft paper isetyenziswa ngokuqhelekileyo ukuprintwa kweekhava zeengxelo zemali, iimvilophu, ukupakishwa kwempahla, iingxowa zamaxwebhu, izikhwama zolwazi, izikhwama zezandla, iibhokisi zefayile, izikhwama zefayile, njl.
Ukucaciswa kwephepha le-kraft
Isetyenziswa ngokuqhelekileyoiphepha le-kraftineenkcukacha ezahlukeneyo ezifana ne-60g/m2, 70g/m2, 80g/m2, 100g/m2, 120g/m2, 150g/m2 nkqu 250~450g/m2.
Iimpawu zephepha le-kraft
Izinto eziluncedo:Iphepha le-Kraft lineenzuzo zokuqina okulungileyo, ukuthungwa okunzima kunye nokuqina, ukukrazula nokuqhekeka ngokulula, kunye nokumelana nokugqoka kunye nokukrazula.
Izinto ezingeloncedo:kraft iphepha umphezulu iphepha uburhabaxa, kulula ukuvela kwi buckle phantsi pick, iinwele eziwa, de umgubo phenomenon, ubumhlophe, flatness, ukuguda akulunganga.
Ukusetyenziswa kwezakhono zephepha le-kraft
① Ukuxhoma kunye nokulungelelanisa unyango olumanzi: inyathelo lokuqala ukuya kumphezulu wokungalingani kwaye lisusiwe iphepha eliphukileyo, inyathelo lesibini liya kuba liphepha lephepha, uthuthu lwephepha olucocekileyo, ukuxhoma ukomisa unyango, ukwenzela ukuba ubushushu kunye nokufuma kwephepha le-kraft kunye ne-offset. iqondo lobushushu workshop yoshicilelo kunye nokufuma ukugcina engaguquguqukiyo.Iphepha leKraftemva kokuxhoma ukomisa unyango lokufuma, ibekwe phezu kwesipakisho sephepha sicinezele i-splint yephepha, ngamatye amakhulu, i-iron plate compaction, ukuphepha i-fluffy yephepha ayiqini.Ukwenza oko kunokuphepha ngokufanelekileyo ukuvela kwephepha le-kraft ngenxa yokungalingani komswakama ovela kwi-phenomenon ye-buckling phantsi kwepiki.
② khetha imodeli elungileyo: ngenxa ye-80g/m2 etyebileyo yephepha le-kraft, kwi-nozzle yokuhanjiswa kwephepha kaninzi ayikwazi ukufunxa iphepha, ngoko ke xa ubukhulu bephepha le-kraft ≥ 80g/m, kungcono ukuba ungasebenzisi amancinane amane okanye asibhozo avulekileyo. umatshini woshicilelo weoffset.Ukongeza, ngenxa yobubanzi bephepha elincinci, kulula ukuphindaphinda kabini okanye ukungaphumeleli kwamaphepha amaninzi, okanye iphepha elijijekileyo ekuhanjisweni kwebhodi.Kwaye kunye ne-folio offset press okanye i-full-open-open-offset press printing ≥ 80g / m ye-kraft paper, umphumo uya kuba ngcono.
③ Lungisa inkqubo yokuhanjiswa kwephepha kumatshini wokushicilela: ubukhulu bephepha bukhulu kulula ukubangela iingozi zokumisa, ngoko ke ngaphambi kokuba umatshini wokushicilela ube phambi kolawulo lwe-punch, ulawulo lwe-skew, ulawulo oluphindwe kabini kunye nezinye izixhobo zombane ezifanelekileyo, ukuthintela iphepha krafti ngaphezulu komatshini roll embi omnye.Kufuneka ilungelelaniswe kubungakanani bomthamo wokufunxa umlomo wombhobho wokufunxa, umlomo wephepha wokufunxa kunye nombhobho wokufunxa wephepha ukusebenzisa ububanzi kunye nobungqingqwa yiringi enkulu yerabha.
④ gcina i-cylinder yokushicilela kunye nomgama we-cylinder yerabha ungatshintshanga: lungisa umgama ophakathi we-cylinder ye-impression kunye ne-rubber cylinder kwaye ugcine umgama ophakathi ungatshintshi, xa uprinta i-250 ~ 450g / m yephepha le-kraft, lo mgama ophakathi ungandiswa nge-0.2 ~ 0.4 mm.uburhabaxa bephepha lomphezulu we-kraft, ukuguda akubi, ukuqina kwephepha kuncinci kakhulu kunephepha le-copperplate, iphepha le-offset, ke ngoko, ukuprinta iphepha le-kraft, kodwa ngokuhambelana nokonyusa uxinzelelo lokushicilela.Xa kushicilelwaiphepha le-kraftubukhulu ≥ 400g / m, ipleyiti yoshicilelo cylinder kunye umsantsa irabha cylinder 3.95mm, cylinder irabha kunye nombono cylinder gap uhlengahlengiso for 3.40mm, iyonke iphakheji lining yesilinda ipleyiti yoshicilelo 0.65 ~ 0.75mm, iyonke iphakheji lining lining irabha cylinder for 3.15 ~ 3.35mm.Ukuba iphepha lokushicilela ukusuka kwingqimba ukuya kwincinci, kufuneka litsalwe kumgca wepleyiti yokushicilela kubukhulu obuncitshisiweyo bePackage lining, kunye ne-rubber cylinder package;ukuba iphepha ukusuka kwibhityi ukuya kwingqimba, kufuneka litsalwe ukusuka kwi-cylinder yerabha ukunyusa ubukhulu bomgca wepakethe, kunye neplate yokushicilela ipakethe yesilinda.
⑤ Iphepha le-kraft liphezulu, likhululekile, lilula ukuba ngumgubo, iinwele, ngoko xa ushicilela ukukhuhla ngenkuthalo i-cylinder yerabha kunye ne-cylinder yepleyiti yokushicilela, ukuphepha iinwele zephepha, umgubo wephepha onamathele kwi-cylinder yerabha kunye ne-cylinder yepleyiti yokushicilela kunye nokuchaphazela ukudluliselwa kwe-inki, okukhokelela kwimizobo ephuma kwipleyiti, ukunqongophala komqolo owaphukileyo wosiba.Ukuba kuqubisana ehlotyeni xa yoshicilelo monochrome, kraft iinwele iphepha, umgubo iingxaki ezinzulu, zingaprintwa phambi umaleko ukwaleka kwamanzi, nto leyo enokunciphisa ngempumelelo iinwele iphepha, isenzeko umgubo, ukuze iphepha ngaphezulu flat.
