I-1, i-back coating noma i-back printing back coating iyi-coating evikelayo ngemuva kwephepha lesisekelo ukuvimbela ukukhishwa kwemfucuza, ngemva kokuhlehlisa ilebula ezungeze isibopho sokunamathela ephepheni elingaphansi. Omunye umsebenzi ukwenza izendlalelo eziningi zamalebula. Umsebenzi wokuphrinta ngemuva uwukuphrinta uphawu lokuhweba olubhalisiwe lomkhiqizi noma iphethini ngemuva kwephepha elisekelayo, elidlala indima yokukhangisa kanye nokulwa nokwenza izinto zomgunyathi.

2. I-Surface coating isetshenziselwa ukushintsha izici ezingaphezulu zezinto ezingaphezulu. Isibonelo, thuthukisa ukungezwani kwendawo, ushintshe umbala, ukhulise isendlalelo esivikelayo, ukuze ukwazi ukwamukela kangcono uyinki futhi kulula ukuphrinta, ukuvimbela ukungcola, ukwandisa amandla okunamathela ayinki futhi uvimbele inhloso yokunyathelisa umbhalo nokuchithwa kombhalo. I-Surface coating isetshenziselwa ikakhulukazi izinto ezingabambi, njenge-aluminium foil, iphepha eli-aluminium kanye nezinto ezihlukahlukene zefilimu.

I-3, i-surface material iyinto engaphezulu, ingaphambili yokwamukela umbhalo ophrintayo, ingemuva ukwamukela okunamathiselwe futhi ekugcineni isetshenziswe ezintweni ezizonamathiselwa. Ngokuvamile, zonke izinto eziguquguqukayo eziguquguqukayo zingasetshenziswa njengezindwangu zokuzibamba, njengephepha elivame ukusetshenziswa, ifilimu, i-foil eyinhlanganisela, zonke izinhlobo zezindwangu, amashidi ensimbi amancane kanye nenjoloba, njll. Uhlobo lwendawo luncike ekusetshenzisweni kokugcina kanye nenqubo yokunyathelisa. Izinto ezingaphezulu kufanele zikwazi ukuzivumelanisa nokuphrinta nokuphrinta, zibe ne-inki enhle, futhi zibe namandla anele okwamukela ukucutshungulwa okuhlukahlukene, njengokusika ukufa, ukukhipha udoti, ukusika, ukubhoboza nokulebula.

4, ingcina yokunamathisela iyindawo ephakathi kwempahla yelebula ne-bonding substrate, edlala indima yokubopha. Ngokusho izici zayo zingahlukaniswa unomphela futhi esikhiphekayo izinhlobo ezimbili. Iza ngezindlela ezihlukahlukene ukuze ivumelane nezindawo ezihlukene nezikhathi ezahlukene. I-Adhesive iyingxenye ebaluleke kakhulu yobuchwepheshe bezinto ezizinamathelayo kanye nokhiye wokusebenzisa ilebula yobuchwepheshe.

I-5, ukukhishwa kwe-release coating (ehlanganiswe ne-silicon layer) okungukuthi, ebusweni bephepha elingaphansi elimbozwe nge-silicone ungqimba lwamafutha, eligcotshwe ngamafutha abicah lingenza iphepha elingaphansi libe ukungezwani okuphansi kakhulu, indawo ebushelelezi kakhulu, indima ukuvimbela isibopho sokunamathela ephepheni eliphansi.

I-6, indima yephepha eliphansi ukwamukela ukunamathela kwe-ejenti yokukhululwa, ukuvikela okunamathelayo ngemuva kwento engaphezulu, ukusekela izinto ezingaphezulu, ukuze kube ukusika ukufa, ukukhishwa kwemfucuza nokulebula emshinini wokulebula.7, ukugqoka okuphansi kufana nokwemboza okungaphezulu, kodwa kuhlanganiswe ngemuva kwento engaphezulu, inhloso eyinhloko yokugqoka okuphansi:

(1) ukuvikela impahla engaphezulu, ukuvimbela ukungena kokunamathela.

(2) Khulisa ukungabi lula kwendwangu;

(3) Khulisa amandla okunamathela phakathi kwezinto ezifanayo ezingaphezulu;

(4) Vimbela i-plasticizer endaweni yepulasitiki ekungeneni kokunamathelayo, okuthinta ukusebenza kokunamathela, okuholela ekuncipheni kwamandla okunamathela welebula kanye nelebula liwe.
