Ngokuthuthuka okusheshayo kwemboni yokupakisha nokunyathelisa, ukusetshenziswa kwenqubo yokugxiviza okushisayo kuyanda kakhulu, ikakhulukazi ebhokisini lokupakisha lezimpahla.Ukusetshenziswa kwayo kuvame ukudlala indima yokuqeda ukuthinta, kugqamise itimu yokuklama, futhi kuthuthukise inani elengeziwe lemikhiqizo ukuze kuhlangatshezwane nezidingo zamakhasimende ahlukene okuphrinta.Lesi sihloko sihlelwe nguShanghai rainbow iphaketheukwabelana ngezinhlelo zokusebenza zobuchwepheshe ezintathu okunzima ukuzilawula kunqubo yokugxiviza okushisayo
Inqubo ye-gilding iwukudlulisa ungqimba lwe-aluminium ku-aluminium anodized endaweni engaphansi kwe-substrate usebenzisa isimiso sokudluliswa komshini oshisayo ukwenza umphumela okhethekile wensimbi.Ngokusho kokucaciswa, i-gilding ibhekisela kunqubo yokunyathelisa yokudlulisa okushisayo yokunyathela i-anodized hot stamping foil (iphepha elishisayo lokunyathela) endaweni engaphansi kwe-substrate ngaphansi kwezinga lokushisa elithile nokucindezela.Njengoba into eyinhloko esetshenziselwa ukukhanda i-anodized aluminium foil, i-gilding ibizwa nangokuthi i-anodized hot stamping.
01 Ukunyathela kuvanishi we-UV
I-UV glazing ingathuthukisa ukucwebezela kwemikhiqizo ephrintiwe, futhi umphumela wayo oyingqayizivele wokucwebezela ubonwa iningi lamakhasimende.Ukugxiviza okushisayo ku-varnish ye-UV kungathola umphumela omuhle kakhulu wokubuka, kodwa inqubo yako kunzima ukuyilawula.Lokhu kungenxa yokuthi ukufaneleka kwesitembu esishisayo se-varnish ye-UV akukakavuthwa, futhi ukwakheka kwe-resin nezithasiselo zevarnish ye-UV akusizi ekugxivizeni okushisayo.
Kodwa-ke, lapho ucubungula imikhiqizo ethile, inqubo yokugxiviza okushisayo ku-varnish ye-UV ayinakugwenywa.Inqubo yokuqala yokukhiqiza idinga ukudlula ezinqubweni ezintathu zokuphrinta kwe-offset, ukugxiviza okushisayo nokupholisha.Ngemva kokusetshenziswa kwezinto ezintsha, ukunyathelisa nokupholishwa kwe-offset kungaqedwa kanye bese kwenziwa isitembu esishisayo.Ngale ndlela, inqubo eyodwa ingancishiswa futhi umthelela wokwelapha owodwa we-UV ungancishiswa, ngaleyo ndlela ugweme ukwenzeka kwephepha lokusika ukuqhuma kombala, ukuthuthukisa kakhulu ukusebenza kahle kokukhiqiza nokunciphisa izinga le-scrap.
Kodwa-ke, ngalesi sikhathi, kuyadingeka ukufaka isitembu esishisayo ku-varnish ye-UV, okubeka phambili izidingo eziphakeme kakhulu ze-varnish ye-UV kanye nesitembu esishisayo esifakwe nge-anodized.Kufanele kuqashelwe lezi zici ezilandelayo.
1) Lapho ucwebezela, qaphela ukulawula inani le-varnish.I-varnish ye-UV kufanele ibe nogqinsi oluthile ukuze kuzuzwe umphumela wokukhanya okuphezulu, kodwa ukuvanisha okuminyene kakhulu akulungile ekugxivizeni okushisayo.Ngokuvamile, lapho ungqimba lwe-varnish ye-UV lumbozwe ukuphrinta kwe-offset, inani lokupholisha lilinganiselwa ku-9g/m2.Ngemva kokufinyelela leli nani, uma ukukhanya kwesendlalelo se-varnish ye-UV kudinga ukuthuthukiswa, ukukhanya nokukhanya kwesendlalelo se-varnish kungathuthukiswa ngokulungisa imingcele yenqubo yokumboza (i-engeli yocingo lwe-roller yesikrini nenombolo yezintambo zesikrini, njll.) kanye nokusebenza kwemishini yokunyathelisa (ingcindezi yokunyathelisa nesivinini sokunyathelisa, njll.).
I-2) Zama ukuqinisekisa ukuthi ukugqoka kwe-varnish kweqoqo lonke lemikhiqizo kuzinzile, futhi isendlalelo se-varnish kufanele sibe mncane futhi sicaba.
3) Ukukhetha okunengqondo kwezinto ezishisayo zokunyathela.Kudingeka ukuthi izinto ezishisayo zokugxiviza zibe nokumelana nezinga lokushisa eliphezulu, ukunamathela okuhle, nokuhlobana okuhle phakathi kongqimba lwazo lokunamathisela kanye neresin yokuvanisha ye-UV.
I-4) Lungisa ngokunembile izinga lokushisa nokucindezela kwenguqulo ye-stamping eshisayo, ngoba ukucindezela okuphezulu kakhulu kanye nezinga lokushisa kuzolimaza ukusebenza kweyinki futhi kwenze ukunyathela okushisayo kube nzima kakhulu.
5) Isivinini sokunyathela esishisayo akufanele sisheshe kakhulu.
02 Kuyashisa ngaphambi kokuphrinta
Inqubo yeisitembu esishisayo esilandelwa ukuphrintangokuvamile ukuthuthukisa umuzwa wensimbi obonakalayo wephethini ephrintiwe, kanye nokusebenzisa indlela yenqubo yokugxiviza okushisayo elandelwa ukuphrinta kwemibala emine kuphethini yesitembu esishisayo.Imvamisa, amaphethini ombala kancane kancane kanye nensimbi angaphrintwa ngembondela yamachashazi, enokusebenza okuhle kokubuka.Izinto ezilandelayo zizoqashelwa ngesikhathi sokusebenza kwangempela kwalolu hlelo:
1) Izidingo zokugxiviza okushisayo kwe-anodized aluminium ziphezulu kakhulu.Ngesikhathi esifanayo, isikhundla sokugxiviza esishisayo siyadingeka ukuze sinembile kakhulu.Ingaphezulu lephethini lokunyathela elishisayo libushelelezi futhi liyakhanya, ngaphandle kwamabhamuza, ukunamathisela, ukuklwebheka okusobala, njll., futhi imiphetho yephethini yesitembu esishisayo ayikwazi ukuba nokuhlehlisa okusobala;
I-2) Ngamakhadi amhlophe namakhadi engilazi, kufanele kuqashelwe ngokukhethekile ukuvikelwa kwemikhiqizo eqediwe, futhi ithonya lezici ezihlukahlukene ezimbi ezifana nokuguqulwa kwephepha kufanele kuncishiswe ngesikhathi senqubo yokukhiqiza, okuzosiza kakhulu inqubo ebushelelezi. isitembu esishisayo kanye nokwenza ngcono izinga lokufaneleka komkhiqizo;
3) I-adhesive layer ye-anodized aluminium kufanele ibe nokunamathela okuphezulu kakhulu (ungqimba olunamathelayo olukhethekile luzothuthukiswa emikhiqizweni yephakheji kagwayi uma kunesidingo), futhi ukungezwani okungaphezulu kwe-aluminium anodized akufanele kube ngaphansi kuka-38mN/m;
I-4) Ngaphambi kokushaya isitembu esishisayo, kuyadingeka ukukhipha ifilimu yokumisa, futhi uqinisekise ukunemba kokugxiviza okushisayo nokuphrinta ngokweqile ngokulungisa indawo eqondile yepuleti elishisayo;
5) Ngaphambi kokukhiqizwa ngobuningi, imikhiqizo eshisayo ngaphambi kokuphrinta kufanele ibe ngaphansi kokuhlolwa kokudonsa ifilimu.Indlela yokusebenzisa i-intshi engu-1 ye-tape ebonakalayo ukuze udonse ngokuqondile i-aluminium anodized enesitembu esishisayo, futhi ubheke ukuthi kukhona impushana yegolide ewayo, engaphelele noma engavikelekile yokushisa eshisayo, engavimbela inani elikhulu lemikhiqizo yemfucuza enqubweni yokunyathelisa;
6) Lapho wenza ifilimu, naka ububanzi bokunwebeka obuhlangothi olulodwa, okufanele ngokuvamile lube phakathi kuka-0.5mm.
03 I-Holographic positioning isitembu esishisayo
I-Holographic positioning hot stamping ingasetshenziswa kumaphrinti anamaphethini aphikisana nomgunyathi, athuthukise kakhulu amandla okulwa nomgunyathi wemikhiqizo, futhi athuthukise nekhwalithi yemikhiqizo.I-Holographic positioning hot stamping idinga ukulawula okuphezulu kakhulu kwezinga lokushisa, ingcindezi kanye nesivinini, futhi imodeli yesitembu esishisayo nayo inomthelela omkhulu kumphumela wayo.
Ku-holographic positioning hot stamping, ukunemba kwe-overprint kuhlobene ngokuqondile nekhwalithi yomkhiqizo.Ifilimu yokugxiviza eshisayo kufanele incishwe futhi inwetshwe ngo-0.5mm ohlangothini olulodwa.Ngokuvamile, isitembu esishisayo esibeka endaweni ye-holographic sithatha isitembu esishisayo esingenalutho.Ngaphezu kwalokho, ikhesa ye-holographic positioning hot stamping material kufanele ifane, futhi iphethini kufanele ihlukaniswe ngokulinganayo, ukuze umshini ukwazi ukulandelela ngokunembile ikhesa yesitembu esishisayo.
04 Ezinye izinyathelo zokuphepha:
1) I-aluminium ye-anodized efanele kufanele ikhethwe ngokuya ngohlobo lwe-substrate.Uma ushisa isitembu, kufanele uwazi kahle izinga lokushisa, ingcindezi kanye nesivinini sokunyathela okushisayo, futhi ubaphathe ngendlela ehlukile ngokwezinto ezihlukene zokugxiviza ezishisayo nezindawo.
2) Iphepha, uyinki (ikakhulukazi uyinki omnyama), uwoyela owomile, ingcina eyinhlanganisela, njll. enezakhiwo ezifanele kuyokhethwa.Izingxenye ezishisayo zokugxiviza kufanele zigcinwe zomile ukuze kugwenywe ukubola noma ukulimaza ungqimba olushisayo lokugxiviza.
3) Ngokuvamile, ukucaciswa kwe-aluminium anodized ngu-0.64m × One 120m roll, ibhokisi elilodwa kuyo yonke imiqulu eyi-10;Imiqulu emikhulu enobubanzi obungu-0.64m, ubude be-240m noma i-360m noma ezinye izicaciso ezikhethekile zingenziwa ngezifiso.
4) Ngesikhathi sokugcina, i-aluminiyamu ene-anodized izovikelwa ekucindezelweni, emswakameni, ekushiseni naselanga, futhi ibekwe endaweni epholile nengenawo umoya.
