Ngokuthuthuka okusheshayo kwemboni yokupakisha nokuphrinta, ukusetshenziswa kwenqubo yokufaka izitembu ezishisayo kuyanda kakhulu, ikakhulukazi ebhokisini lokupakisha lezimpahla. Ukusetshenziswa kwayo kungadlala indima yokuqeda, kugqamise itimu yokuklama, futhi kuthuthukise inani elengeziwe lemikhiqizo ukuze kuhlangatshezwane nezidingo zamakhasimende ahlukahlukene okuphrinta. Lesi sihloko sihlelwe nguIphakheji yothingo lwaseShanghaiukwabelana ngezinhlelo zokusebenza ezintathu zobuchwepheshe okunzima ukuzilawula enkambisweni yokunyathela okushisayo
Inqubo yokugcoba iwukudlulisa ungqimba lwe-aluminium ku-aluminium e-anodized surface kusetshenziswa isimiso sokudlulisa ngokucindezela okushisa ukuze kwakheke umphumela okhethekile wensimbi. Ngokusho kwencazelo, i-gilding ibhekisela enkambisweni yokuphrinta yokudlulisa ukushisa yokunyathela i-foil eshisayo e-anodized (iphepha elishisayo) endaweni engaphansi ngaphansi kwezinga lokushisa elithile kanye nengcindezi. Njengoba izinto eziyinhloko ezisetshenziselwa ukugcoba i-foil ye-aluminium e-anodized, i-gilding ibizwa nangokuthi i-anodized hot stamping.
01 Ukunyathela i-varnish ye-UV
Ukugqwala kwe-UV kungathuthukisa ukucwebezela kwemikhiqizo ephrintiwe, futhi umphumela wayo oyingqayizivele wokucwebezela okuphezulu uqashelwa iningi lamakhasimende. Ukugqwala okushisayo ku-varnish ye-UV kungaba nomphumela omuhle kakhulu wokubuka, kodwa inqubo yakho kunzima ukuyilawula. Lokhu kungenxa yokuthi ukufaneleka kwe-varnish ye-UV ekugqwala okushisayo akukavuthwa, futhi ukwakheka kwe-resin kanye nezithasiselo ze-varnish ye-UV akuhambisani nokugqwala okushisayo.
Kodwa-ke, lapho kucutshungulwa eminye imikhiqizo, inqubo yokunyathela ngokushisa ku-varnish ye-UV ayinakugwenywa. Inqubo yokuqala yokukhiqiza idinga ukudlula ezinqubweni ezintathu zokunyathelisa nge-offset, ukunyathela ngokushisa kanye nokupholisha. Ngemva kokusetshenziswa kwezinto ezintsha, ukunyathelisa nge-offset kanye nokupholisha kungaqedwa kanye bese kwenziwa ukunyathela ngokushisa. Ngale ndlela, inqubo eyodwa ingancishiswa futhi umthelela wokupholisha nge-UV eyodwa ungancishiswa, ngaleyo ndlela kugwenywe ukuqhuma kombala wokusika iphepha, okuthuthukisa kakhulu ukusebenza kahle kokukhiqiza kanye nokunciphisa izinga lokusikwa.
Kodwa-ke, ngalesi sikhathi, kuyadingeka ukufaka isitembu esishisayo ku-varnish ye-UV, okubeka phambili izidingo eziphezulu kakhulu ze-varnish ye-UV kanye ne-anodized yesitembu esishisayo. Kufanele kunakwe izici ezilandelayo.
1) Uma ugcoba, naka ukulawula inani le-varnish. I-varnish ye-UV kumele ibe nobukhulu obuthile ukuze kufezwe umphumela wokukhanya okuphezulu, kodwa i-varnish ejiyile kakhulu ayilungile ekushiseni okushisayo. Ngokuvamile, lapho ungqimba lwe-varnish ye-UV lumbozwe ngokuphrinta kwe-offset, inani lokupholisha lingaba ngu-9g/m2. Ngemva kokufinyelela leli nani, uma ukukhanya kwengqimba ye-varnish ye-UV kudinga ukuthuthukiswa, ukuthamba nokukhanya kwengqimba ye-varnish kungathuthukiswa ngokulungisa amapharamitha enqubo yokumboza (i-engeli yentambo yesikrini se-roller yokumboza kanye nenani lezintambo zesikrini, njll.) kanye nokusebenza kwemishini yokuphrinta (ingcindezi yokuphrinta kanye nesivinini sokuphrinta, njll.).
2) Zama ukuqinisekisa ukuthi ungqimba lwe-varnish lweqoqo lonke lemikhiqizo luzinzile, futhi ungqimba lwe-varnish kufanele lube luncane futhi lube yisicaba.
3) Ukukhetha okunengqondo kwezinto zokunyathela ezishisayo. Kuyadingeka ukuthi izinto zokunyathela ezishisayo zibe nokumelana nokushisa okuphezulu, ukunamathela okuhle, kanye nokusondelana okuhle phakathi kwesendlalelo sazo sokunamathela kanye ne-resin ye-varnish ye-UV.
4) Lungisa ngokunembile izinga lokushisa kanye nengcindezi yenguqulo yokunyathela okushisayo, ngoba ingcindezi ephezulu kakhulu kanye nezinga lokushisa kuzolimaza ukusebenza kweyinki futhi kwenze ukunyathela okushisayo kube nzima kakhulu.
5) Isivinini sokunyathela esishisayo akufanele sibe sishesha kakhulu.
02 Okushisayo ngaphambi kokuphrinta
Inqubo yeukunyathelisa okushisayo kulandelwe ukuphrintaNgokuvamile kuhloswe ukuthuthukisa umuzwa wesithombe sensimbi wephethini ephrintiwe, kanye nokwamukela indlela yenqubo yokufaka isitembu esishisayo elandelwa ukuphrinta ngemibala emine kuphethini yokufaka isitembu esishisayo. Ngokuvamile, amaphethini ombala ahamba kancane kancane nawensimbi angaphrintwa nge-dot overlay, ebonakala kahle. Izinto ezilandelayo kufanele ziqashelwe ngesikhathi sokusebenza kwangempela kwale nqubo:
1) Izidingo ze-aluminium e-anodized stamping eshisayo ziphakeme kakhulu. Ngesikhathi esifanayo, indawo yokunyathela eshisayo iyadingeka ukuze ibe nembe kakhulu. Ubuso bephethini yokunyathela eshisayo bubushelelezi futhi bukhanya, abunamabhamuza, unamathisele, imihuzuko esobala, njll., futhi imiphetho yephethini yokunyathela eshisayo ayikwazi ukuba nokugoba okusobala;
2) Kumakhadi amhlophe namakhadi engilazi, kufanele kuqashelwe ngokukhethekile ukuvikelwa kwemikhiqizo eqediwe kancane, futhi ithonya lezici ezahlukahlukene ezimbi njengokuguqulwa kwephepha kufanele lincishiswe ngesikhathi senqubo yokukhiqiza, okuzosiza kakhulu inqubo ebushelelezi yokunyathelisa okushisayo kanye nokuthuthukiswa kwezinga lokufaneleka komkhiqizo;
3) Ingqimba yokunamathela ye-aluminiyam e-anodized kufanele ibe nokunamathela okuphezulu kakhulu (ingqimba yokunamathela ekhethekile kufanele yakhelwe imikhiqizo yephakheji kagwayi uma kudingeka), futhi ukucindezelwa kobuso be-aluminiyam e-anodized akufanele kube ngaphansi kuka-38mN/m;
4) Ngaphambi kokunyathela okushisayo, kuyadingeka ukukhipha ifilimu yokubeka, futhi uqinisekise ukunemba kokunyathela okushisayo nokunyathelisa okungaphezu kokunyatheliswa ngokulungisa indawo eqondile yepuleti lokunyathela elishisayo;
5) Ngaphambi kokukhiqizwa ngobuningi, imikhiqizo eshisayo ngaphambi kokuphrinta kumele ihlolwe ukudonsa ifilimu. Indlela iwukusebenzisa itheyiphu ekhanyayo engu-1 intshi ukudonsa ngqo i-aluminium eshisayo ene-anodized stamped stamped, nokubheka ukuthi kukhona yini i-golden powder ewayo, engaphelele noma engavikelekile, okungavimbela inani elikhulu lemikhiqizo elahliwe enkambisweni yokuphrinta;
6) Uma wenza ifilimu, naka ububanzi bokunwebeka obungakwesobunxele, okufanele bube ngaphakathi kuka-0.5mm.
03 Ukubeka i-Holographic ukunyathela okushisayo
Ukunyathela okushisayo kokubeka i-Holographic kungasetshenziswa kumaphrinti anephethini yokulwa nombumbulu, okuthuthukisa kakhulu ikhono lokumelana nombumbulu lemikhiqizo, futhi kuthuthukise nekhwalithi yemikhiqizo. Ukunyathela okushisayo kokubeka i-Holographic kudinga ukulawulwa okuphezulu kakhulu kwezinga lokushisa, ingcindezi kanye nesivinini, futhi imodeli yokunyathela okushisayo nayo inethonya elikhulu emphumeleni wayo.
Ekunyathelweni kwe-holographic positioning hot stamping, ukunemba kokunyatheliswa okungaphezulu kuhlobene ngqo nekhwalithi yomkhiqizo. Ifilimu yokunyathelisa eshisayo kufanele incishiswe futhi inwetshwe ngo-0.5mm ohlangothini olulodwa. Ngokuvamile, ukunyathelisa okushisayo kwe-holographic positioning kusebenzisa ukunyathelisa okushisayo okungenalutho. Ngaphezu kwalokho, ikhesa lezinto zokunyathelisa ezishisayo ze-holographic positioning kufanele lifane, futhi iphethini kufanele ihlukaniswe ngokulinganayo, ukuze umshini ukwazi ukulandelela ngokunembile ikhesa lokunyathelisa elishisayo.
04 Ezinye izinyathelo zokuphepha:
1) I-aluminiyamu e-anodized efanele kumele ikhethwe ngokuya ngohlobo lwe-substrate. Uma unyathela ngokushisa, kufanele uqonde izinga lokushisa, ingcindezi kanye nesivinini sokunyathela ngokushisa, bese uziphatha ngendlela ehlukile ngokuya ngezinto ezahlukene zokunyathela ngokushisa nezindawo.
2) Iphepha, uyinki (ikakhulukazi uyinki omnyama), uwoyela owomile, inhlaka ehlanganisiwe, njll. enezakhiwo ezifanele kufanele ikhethwe. Izingxenye zokunyathela ezishisayo kumele zigcinwe zomile ukuze kugwenywe ukushiswa noma ukulimala kwengqimba yokunyathela eshisayo.
3) Ngokuvamile, incazelo ye-aluminiyamu e-anodized ingu-0.64m × Umqulu owodwa ongu-120m, ibhokisi elilodwa kuwo wonke ama-roll ayi-10; Ama-roll amakhulu anobubanzi obungu-0.64m, ubude obungu-240m noma u-360m noma ezinye izici ezikhethekile angenziwa ngokwezifiso.
4) Ngesikhathi sokugcina, i-aluminiyamu e-anodized kufanele ivikelwe ekucindezelweni, umswakama, ukushisa kanye nelanga, bese ibekwa endaweni epholile nenomoya.
