Malunga nezakhono zokuvelisa iphepha le-kraft
Ibhokisi yephepha leKraftukuprinta kunokusebenzisa i-flexo printing, i-gravure printing, i-offset yoshicilelo kunye neenkqubo zokushicilela isikrini.Logama nje uyinkosi eziyimfuneko zobugcisa yoshicilelo, baqhelene nokufaneleka yoshicilelo inki yoshicilelo kunye krafti iphepha, khetha kwaye wabele inki ngokufanelekileyo, kunye nolawulo izixhobo parameters, ungafumana iziphumo ezingcono kakhulu umgangatho..

Nangona kunjalo, kwezinye iifektri ezincinci zokupakisha kunye nokushicilela, okanye iifektri ezincinci ezisanda kufakwa kwimveliso kunye nokusebenza kwe-kraft paper ukupakisha, kuya kuhlala kukho iingxaki kumgangatho wemveliso ngenxa yeemeko ezahlukeneyo.Oku kulandelayo ngamanqaku athile ekufuneka athathelwe ingqalelo xa kushicilelwa iphepha lekrafti:

Nika ingqalelo kwimibala yokushicilela
Ukuze ufumane ukuveliswa kombala ongcono kushicilelo lwekhathoni ye-kraft, kunzima ngakumbi kunokushicilela ngephepha le-SBS.Ngokukodwa, ukuveliswa kombala ngokuchanekileyo kwibhodi ye-kraft eqhelekileyo kufuna ukunyamekelwa ngakumbi kunokushicilela kwibhodi ye-kraft ye-bleached.Ekubeni iphepha eliqhelekileyo le-kraft ngokwalo linombala omnyama omnyama, umphumo we-inki yokushicilela yahluke kakhulu kuleyo yokushicilela kwiphepha elixutywe.Ngoko ke, kungcono ukusebenzisa ii-inks ezinemibala eqaqambileyo kwaye usebenzise imibala ekhangayo ngakumbi, ukwenzela ukuba umphumo wokushicilela ube ngcono.Imibala ye-pastel kunye ne-tints yeyona nto inzima kakhulu ukufezekisa iziphumo ezinqwenelekayo zokuxinana kwe-inki, i-opacity, kunye nokuchasana kwe-abrasion.Kwakhona, ukuba kuyimfuneko, ukongeza umhlophe omncinci kwi-inki kuqala kuya kunceda ukufezekisa i-pastel efunwayo okanye i-tint, eluncedo kakhulu ukuphindaphinda imibala ye-pastel kunye ne-pastel.Ngokukhula okukhulayo kobugcisa bokushicilela, abanye abavelisi bade basebenzise i-inki ye-UV ukuze baphucule ngokufanelekileyo isiphumo sombala woshicilelo.Okwangoku, phantse bonke abavelisi be-inki baye benza ii-inki zebhodi yombala wokuqala, kwaye abenzi be-inki abaninzi baye benza ii-inki zokushicilela kwiphepha le-kraft.Ngoko ke, ngaphambi kokumisela isisombululo esona sisombululo somsebenzi, kufuneka udibane nomenzi we-inki, ukhethe i-inki yefomula eyahlukeneyo ngokweemfuno zoshicilelo lwefektri, bhekisa kumbala we-inki wombala obonelelwa ngumenzi weinki kunye nesiphumo soshicilelo lwe-inki amaphepha ahlukeneyo, kwaye ekugqibeleni unqume eyona ifanelekileyo kuwe.Eyona inki.

Ukhetho olufanelekileyo lwe-inki
Ukususela kwikraft iphepha ibhokisi yepizzayahlukile kwikhadibhodi ye-SBS kunye nephepha lokuprinta ngokubanzi, aliguquguquki, likhululekile kunekhadibhodi elifakwe i-bleached, linama-pores amaninzi phezu komhlaba, kwaye linokungena okunamandla, njl., efunekayo kwisicelo kunye nokufakwa kwe-inki.Yenza ingqwalasela ebanzi.Ngokomzekelo, ngokumalunga nohlalutyo lweempawu zephepha le-kraft, ngokuqhelekileyo kungcono ukusebenzisa ushicilelo lwe-flexographic, kwaye akufanelekanga ukusebenzisa umatshini wokushicilela we-offset wephepha elipheleleyo lokuprinta iphepha eliqinileyo le-kraft.Ngenxa yobuso oburhabaxa bephepha le-kraft, ukuthamba okuthambileyo, ukufunxwa kwe-inki eyomeleleyo, umbala ongacacanga weemveliso eziprintiweyo, kunye nesenzeko se-inki sokutsalwa komphezulu wemicu yephepha (ekwaziwa njengokutsalwa kwewulu yephepha) ngexesha loshicilelo.

Ukuveliswa kwekhadibhodi kunye nokucubungula
Ngenxa yeempawu ezikhululekileyo, ezinobuqhophololo kunye nezikhulu ze-unglazedibhokisi yesonka kraft, kulula ukuvelisa uthuli ngexesha lokuvelisa kunye nokulungiswa kwekhadibhodi, ngoko kufuneka kuhlawulwe ingqalelo ekukhuseleni nasekunciphiseni umonakalo obangelwa uthuli.

I-Post-press die-cutting
Ngenxa yesakhiwo esikhethekileyo sephepha eliphambili le-kraft yemibala, amandla ayo makhulu kwaye iimpawu zayo zefiber ziyaqikelelwa, ngoko ke ineempawu ezingcono zokusetyenzwa ezifana nokufaka i-embossing, ukusika ukufa kunye ne-die-engraving.Kodwa kumandla aphezulu kunye neentsinga eziphambili, iphepha le-kraft liyafuneka ukuba lidlule imigca enzulu yokungena ukunqanda ukuphinda kuphindwe.Ukongezelela, iimela zokusika ezifayo zifuneka ukuba zibe bukhali.Ngenxa yamandla aphezulu e-fiber yephepha le-kraft, i-indentation encinci iyafuneka kumgca we-perforation, kwaye i-nicks efunekayo kwi-perforation kufuneka ibe yincinci kwaye incinci.

I-Gluing kunye nokudibanisa okufanelekileyo
I-high-solid, i-high-viscosity resin adhesive ifanelekile kwi-bonding ephantsi yokushisa.Kufuneka ipholiswe ngaphambi kokuba ifakwe kwikhadibhodi ye-kraft, kwaye ayikwazi ukungena kwikhadibhodi ngobuninzi obukhulu.Izincamathelisi zemveli ezishushu ezinyibilikayo zikwafanelekile kwikhadibhodi yekraft kunye ne-polyester-glazed kraft paper.Umphumo ngomlinganiselo ulungile.Ngenxa yobunzima bayo obulula, i-kraft paperboard ifanelekile ukuveliswa koomatshini beefolda ezikhawulezayo.

Ukhetho olufanelekileyo lwephepha
Ukuze kuhlangatyezwane neemfuno zokupakisha ezintsha zabavelisi bokutya, i-kraft paperboard engafakwanga bleach ineempawu ezahlukileyo kwibhodi efakwe iblitshi, ezifana neempahla ezibhakiweyo okanye iimveliso zasekhaya ezifana nokutya okulula.Inkangeleko emdaka yendalo ye-primary kraft paper inembonakalo enempilo, ye-retro.Enyanisweni, ukungafani nje phakathi kwembonakalo ekhethekileyo yephepha le-kraft kunye nomthamo omkhulu wokupakishwa okumhlophe kunokwenza umkhiqizo ubonakale.Kuba ukupakishwa okuninzi kokutya kuyilelwe ukuba kube lula okanye ukusebenza, amandla ephepha le-kraft yenye inzuzo.Ipakethe ezithathayo kufuneka zomelele ngokwaneleyo ukuze zivale ukutya komthengi ngaphandle kokukuphula.Ngomqondiso ofanayo, iikomityi zesiselo kufuneka zikwazi ukubambelela kwindawo efumileyo ukuze ikofu ingahambi phantsi ethangeni lomthengi.Amandla ikwayeyona nto iphambili kuqwalaselo lokutya okukhenkcezisiweyo kuba ukupakishwa kokutya okukhenkcezisiweyo akunako ukuguqula, ukukrazula, ukugqwesa, okanye ukufunxa ukufuma okuninzi ngexesha lomjikelo womkhenkce/wokunyibilika.Ngokumalunga nokusebenza kulo mba, i-kraft paper ingcono kune-homogeneous bleached kraft paper.
