Indlela yokulungisa inqubo yokuphrinta ye-inki ye-flexo ngephepha lebhokisi elihlukile
Izinhlobo ezijwayelekile zephepha lesisekelo elisetshenziselwa iphepha elingaphezulu kwebhokisi likathayela zifaka: iphepha lebhodi leziqukathi, i-liner paper, ikhadibhodi le-kraft, iphepha lebhodi letiye, iphepha lebhodi elimhlophe kanye nephepha lebhodi elimhlophe eliboshwe ohlangothini olulodwa. Ngenxa yokuhluka kwezinto zokwenza iphepha kanye nezinqubo zokwenza iphepha zohlobo ngalunye lwephepha lesisekelo, izinkomba ezibonakalayo namakhemikhali, izakhiwo ezingaphezulu kanye nokuphrinta kwamaphepha ayisisekelo okukhulunywe ngenhla ahluke kakhulu. Okulandelayo kuzodingida izinkinga ezidalwe yimikhiqizo yephepha eshiwo ngenhla kunqubo kathayela kayinki wokuphrinta wekhadibhodi.
1. Izinkinga ezibangelwa i-low-gram base paper ibhokisi likashokoledi
Uma i-low-gram base paper isetshenziswa njengephepha elingaphezulu lekhadibhodi likathayela, amamaki awonakele azovela ebusweni bekhadibhodi likathayela. Kulula ukubangela umtshingo futhi okuqukethwe okuyingcaca okudingekayo akukwazi ukuphrintwa engxenyeni ephansi yomtshingo. Uma kubhekwa indawo engalingani yekhadibhodi ewuthayela ebangelwa umtshingo, ipuleti le-resin eliguquguqukayo elikwazi ukuqina kangcono kufanele lisetshenziswe njengepuleti lokuphrinta ukuze kunqotshwe ukungahambi kahle kokuphrinta. Amaphutha acacile futhi adaluliwe. Ikakhulukazi ku-A-type corrugated cardboard ekhiqizwa ngephepha eliphansi lohlelo, amandla okucindezela ayisicaba ekhadibhodi ehlanganisiwe azolimala kakhulu ngemva kokunyatheliswa umshini wokunyathelisa. Kunomonakalo omkhulu.ubucwebeibhokisi
Uma ubuso bekhadibhodi eboshiwe buhluka kakhulu, kulula ukubangela ukungqubuzana kwekhadibhodi elikhuni elikhiqizwe umugqa wamakhadibhodi. Ikhadibhodi elisontekile lizobangela ukuphrinta ngokweqile okungalungile kanye nezikhala zokuphrinta ezingaphandle kwe-gauge zokuphrinta, ngakho-ke ikhadibhodi elisontekile kufanele lenziwe isicaba ngaphambi kokuphrinta. Uma ikhadibhodi likathayela elingalingani linyatheliswa ngenkani, kulula ukubangela ukungahambi kahle. Kuzokwenza futhi ukushuba kwamakhadibhodi kathayela kwehle.
2. Izinkinga ezibangelwa ubulukhuni obuhlukene bephepha lesisekelo iphepha-isipho-packaging
Uma uphrinta ephepheni eliyisisekelo elinendawo emangelengele kanye nesakhiwo esixegayo, uyinki unokungeneka okuphezulu futhi uyinki wokuphrinta woma ngokushesha, kuyilapho uphrinta ephepheni elinobushelelezi obuphezulu, ifayibha eminyene kanye nokuqina, isivinini sokumisa uyinki siyanensa. Ngakho-ke, ephepheni eliqinile, inani lokufaka uyinki kufanele linyuswe, futhi ephepheni elibushelelezi, inani lokufaka uyinki kufanele lincishiswe. Uyinki ophrintiwe ephepheni elingakakhululi woma ngokushesha, kuyilapho uyinki ophrintiwe ephepheni eliwusayizi woma kancane, kodwa ukuphindaphindeka kwephethini ephrintiwe kuhle. Isibonelo, ukumuncwa kukayinki wephepha lebhodi elimhlophe elinamekwe kuphansi kunalelo lephepha lebhokisi kanye nephepha letiye, futhi uyinki woma kancane, futhi ukushelela kwawo kuphakeme kunokwephepha lebhokisi, iphepha le-liner, nephepha letiye. Ngakho-ke, ukulungiswa kwamachashazi amahle aphrintiwe kuyo Izinga libuye liphezulu, futhi ukuphindaphinda kwephethini yayo kungcono kunephepha le-liner, iphepha lekhadibhodi, nephepha lebhodi letiye.
3. Izinkinga ezibangelwa umehluko wokumuncwa kwephepha lesisekelo ibhokisi losuku
Ngenxa yomehluko ekwenzeni iphepha kanye nosayizi wephepha eliyisisekelo, i-calendering, nomehluko wokumboza, amandla okumuncwa ahlukile. Isibonelo, uma ukuphrinta ngokweqile ephepheni lebhodi elimhlophe elimbozwe ngohlangothi olulodwa namakhadi e-kraft, isivinini sokumisa sikayinki sihamba kancane ngenxa yokusebenza okuphansi kokumuncwa. Kancane kancane, ngakho-ke ukugxila kweyinki yangaphambilini kufanele kuncishiswe, futhi i-viscosity ye-inki elandelayo yokuphrinta kufanele inyuke. Phrinta imigqa, izinhlamvu, namaphethini amancane embala wokuqala, futhi uphrinte ipuleti eligcwele kumbala wokugcina, ongathuthukisa umphumela wokuphrinta ngokweqile. Ngaphezu kwalokho, phrinta umbala omnyama ngaphambili nombala okhanyayo ngemuva. Ingakwazi ukumboza iphutha le-overprint, ngenxa yokuthi umbala omnyama unokusibekela okuqinile, okuhambisana nezinga lokuphrinta ngokweqile, kuyilapho umbala okhanyayo unokufakwa okubuthakathaka, futhi akulula ukubhekwa ngisho noma kukhona into ebalekile ekuphrintiwe. ibhokisi losuku
Izimo ezihlukile zokulinganisa endaweni yephepha lesisekelo nazo zizophazamisa ukumuncwa kukayinki. Iphepha elinenani elincane lokulinganisa limunca uyinki owengeziwe, futhi iphepha elinenani elikhulu lokulinganisa limunca uyinki omncane. Ngakho-ke, igebe phakathi kwamarola ayinki kufanele lilungiswe ngokuya ngesimo sephepha, okungukuthi, igebe phakathi kwamarola ayinki kufanele lincishiswe ukuze kulawulwe ipuleti lokuphrinta. kayinki. Kungabonakala ukuthi lapho iphepha lesisekelo lingena efektri, ukusebenza kokumuncwa kwephepha lesisekelo kufanele kuhlolwe, futhi ipharamitha yokumuncwa kwephepha lesisekelo kufanele inikezwe umshini wokunyathelisa we-slotting kanye ne-dispenser ye-inki, ukuze bangakhipha uyinki futhi balungise izinto zokusebenza. Futhi ngokuya ngesimo sokumuncwa samaphepha ayisisekelo ahlukene, lungisa i-viscosity kanye nenani elingu-PH likayinki.
