1. Ukuphrinta
Indlela yokuphrinta ibizwa nge-gravure printing. Ihlukile kokuphrinta kwedijithali, ukuphrinta kwe-gravure kudinga amasilinda ukuze kuphrintwe. Siqopha imiklamo kumasilinda ngokusekelwe emibaleni ehlukene, bese sisebenzisa uyinki ovumelana nemvelo kanye nebanga lokudla ukuze siphrinte. Izindleko zesilinda zincike ezinhlotsheni zezikhwama, osayizi nemibala, futhi kuyindleko yesikhathi esisodwa nje, ngokuzayo lapho u-oda kabusha idizayini efanayo, azisekho izindleko zesilinda. Nakuba ngokuvamile sizogcina amasilinda iminyaka emi-2, uma ngemva kweminyaka emi-2 kungaphinde kuhlelwe kabusha, amasilinda azolahlwa ngenxa yezinkinga ze-oxidation nokugcinwa. Manje sithola imishini yokunyathelisa engu-5 enesivinini esikhulu, engaphrinta imibala engu-10 ngesivinini esingamamitha angu-300/min.

2. Laminating
Isikhwama esiguquguqukayo sibizwa nangokuthi isikhwama se-laminated, i-cos isikhwama esiguquguqukayo kakhulu sifakwe nge-2-4 izendlalelo. I-Lamination iwukugcwalisa ukwakheka kwesikhwama sonke, ukufeza ukusetshenziswa okusebenzayo kwesikhwama. Ungqimba olungaphezulu elokuphrinta, olusetshenziswa kakhulu yi-matt BOPP, i-PET ecwebezelayo, ne-PA(inayiloni); ungqimba olumaphakathi olokusetshenziswa okuthile nokubukeka, njenge-AL, i-VMPET, i-kraft paper, njll; ungqimba lwangaphakathi lwenza konke ukujiya, nokwenza isikhwama sibe namandla, siqandiswe, sivale, sibuyisele emuva, njll, izinto ezijwayelekile yi-PE ne-CPP. Ngemva kokunyathelisa phezu ngaphandle ungqimba surface, sizobe laminated ungqimba maphakathi nangaphakathi, bese laminated nabo nge ungqimba ngaphandle.

3. Ukuqinisa
I-Solidifying, inqubo yokufaka ifilimu elaminethiwe ekamelweni lokomisa ukuze wenze i-ejenti eyinhloko kanye ne-ejenti elaphayo ye-polyurethane adhesive isabela futhi ixhumane futhi ixhumane nobuso be-substrate eyinhlanganisela. Inhloso eyinhloko yokuqinisa ukwenza i-ejenti eyinhloko kanye ne-ejenti yokuphulukisa basabele ngokugcwele phakathi nenkathi ethile yesikhathi ukuze kuzuzwe amandla ahlanganisiwe angcono kakhulu; okwesibili ukususa i-solvent esele enephuzu eliphansi lokubilisa, njenge-ethyl acetate. Isikhathi sokuqinisa sisuka emahoreni angama-24 kuye kwangama-72 sezinto ezahlukahlukene.
4. Ukusika
Ukusika kuyisinyathelo sokugcina sokukhiqiza, ngaphambi kwalesi sinyathelo, kungakhathaliseki ukuthi hlobo luni lwezikhwama oziyalile, lunomqulu wonke. Uma uyala imiqulu yefilimu, khona-ke sizovele siwahlukanise amasayizi afanele nezisindo, uma uyala izikhwama ezihlukene, lokho kuyisinyathelo esisigoqa futhi sizinqume zibe yizicucu, futhi futhi lesi yisinyathelo esifaka uziphu, i-hang hole, i-notch yokudabula, isitembu segolide, njll. Kukhona umshini ohlukene ngokusho kwezinhlobo ezahlukene zesikhwama-isikhwama esiyisicaba, isikhwama sokumisa, isikhwama esiphansi se-gusset. Futhi uma u-oda izikhwama ezinomumo, lesi futhi isinyathelo esisebenzisa isikhunta ukuze sizigoqe zibe sesimweni esifanele osidingayo.
