Ngophuhliso olukhawulezileyo lweshishini lokupakisha nokushicilela, ukusetyenziswa kwenkqubo yokunyathela ngobushushu kuyanda, ingakumbi kwibhokisi yokupakisha yeempahla. Ukusetyenziswa kwayo kunokudlala indima yokugqiba, kuqaqambise umxholo woyilo, kwaye kuphucule ixabiso elongezelelweyo leemveliso ukuze kuhlangatyezwane neemfuno zabathengi abahlukeneyo bokushicilela. Eli nqaku lihlelwe nguIphakheji yomnyama yaseShanghaiukwabelana ngezicelo ezintathu zobuchwepheshe ekunzima ukuzilawula kwinkqubo yokunyathela eshushu
Inkqubo yokusika igolide kukudlulisela umaleko we-aluminiyam kwi-aluminiyam eyosiweyo kumphezulu we-substrate kusetyenziswa umgaqo wokudlulisa i-hot press ukwenza isiphumo esikhethekileyo sesinyithi. Ngokweenkcazo, i-gilding ibhekisa kwinkqubo yokuprinta yokudlulisa ubushushu yokustampa i-anodized hot stamping foil (iphepha lokustampa elishushu) kumphezulu we-substrate phantsi kobushushu obuthile kunye noxinzelelo. Ekubeni izinto eziphambili ezisetyenziselwa ukwenza i-gilding yi-anodized aluminium foil, i-gilding ikwabizwa ngokuba yi-anodized hot stamping.
01 Ukunyathela i-UV varnish
Ukugquma nge-UV kunokuphucula ukuqaqamba kweemveliso eziprintiweyo, kwaye isiphumo sayo esikhethekileyo sokuqaqamba okuphezulu siqatshelwa luninzi lwabathengi. Ukugquma nge-UV varnish kunokufumana isiphumo esihle kakhulu sokubonakala, kodwa inkqubo yayo kunzima ukuyilawula. Oku kungenxa yokuba ukufaneleka kokugquma nge-UV varnish ayikavuthwa, kwaye ukwakheka kwe-resin kunye nezongezo ze-UV varnish azilungele ukugquma nge-hot stamping.
Nangona kunjalo, xa kucutshungulwa ezinye iimveliso, inkqubo yokunyathela ngobushushu kwi-varnish ye-UV ayinakuphepheka. Inkqubo yokuqala yemveliso kufuneka idlule kwiinkqubo ezintathu zokunyathela ngobushushu, ukunyathela ngobushushu kunye nokupolisha. Emva kokuba izixhobo ezintsha zisetyenzisiwe, ukunyathela ngobushushu kunye nokupolisha kungagqitywa kube kanye uze emva koko kunyatheliswe ngobushushu. Ngale ndlela, inkqubo enye ingancitshiswa kwaye impembelelo yokunyathela ngobushushu obunye ingancitshiswa, ngaloo ndlela kuthintelwe ukuqhuma kombala wephepha, okuphucula kakhulu ukusebenza kakuhle kwemveliso kunye nokunciphisa izinga lokusikwa.
Nangona kunjalo, ngeli xesha, kuyimfuneko ukufaka i-hot stamp kwi-UV varnish, nto leyo ebeka phambili iimfuno eziphezulu ze-UV varnish kunye ne-hot stamp anodized. Kufuneka kuqwalaselwe ezi zinto zilandelayo.
1) Xa ugquma, qaphela ukulawula ubungakanani bevarnish. Ivarnish ye-UV kufuneka ibe nobukhulu obuthile ukuze kufezekiswe isiphumo sokukhanya okuphezulu, kodwa ivarnish etyebileyo kakhulu ayilungelanga ukunyathelisa ngobushushu. Ngokubanzi, xa umaleko wevarnish ye-UV ugqunywe yiprinta ye-offset, ubungakanani bokupholisha bumalunga ne-9g/m2. Emva kokufikelela kweli xabiso, ukuba ukukhanya komaleko wevarnish ye-UV kufuneka kuphuculwe, ukuthamba kunye nokukhanya komaleko wevarnish kunokuphuculwa ngokulungelelanisa iiparameter zenkqubo yokugquma (i-engile ye-coating roller screen wire wire kunye nenani lee-screen wire, njl.njl.) kunye nokusebenza kwezixhobo zokuprinta (uxinzelelo lokuprinta kunye nesantya sokuprinta, njl.njl.).
2) Zama ukuqinisekisa ukuba uqweqwe lwevarnish lweqela lonke leemveliso luzinzile, kwaye umaleko wevarnish kufuneka ube mncane kwaye uthambe.
3) Ukukhetha okufanelekileyo kwezinto zokunyathela ezishushu. Kufuneka ukuba izinto zokunyathela ezishushu zibe nokumelana nobushushu obuphezulu, zinamathele kakuhle, kwaye zibe nobudlelwane obuhle phakathi komaleko wazo wokuncamathelisa kunye ne-UV varnish resin.
4) Lungisa ngokuchanekileyo ubushushu kunye noxinzelelo lwenguqulelo yokunyathela okushushu, kuba uxinzelelo oluphezulu kakhulu kunye nobushushu buya konakalisa ukusebenza kwe-inki kwaye kwenze ukunyathela okushushu kube nzima ngakumbi.
5) Isantya sokunyathela esishushu akufuneki sibe sisantya kakhulu.
02 Ishushu ngaphambi kokuprinta
Inkqubo yeisitampu esishushu silandelwa kukuprintangokubanzi kukuphucula ingqiqo yokubona yesinyithi yepateni eprintiweyo, kunye nokwamkela indlela yenkqubo yokunyathela ngobushushu elandelwa kukuprinta ngemibala emine kwipateni yokunyathela ngobushushu. Ngokwesiqhelo, iipateni zombala ezithe chu kancinci nezesinyithi zinokuprintwa nge-dot overlay, enentsebenzo entle yokubona. Le micimbi ilandelayo mayiqatshelwe ngexesha lokusebenza kwale nkqubo:
1) Iimfuneko ze-aluminium e-anodized stamping eshushu ziphezulu kakhulu. Kwangaxeshanye, indawo yokunyathela eshushu iyadingeka ukuze ichaneke kakhulu. Umphezulu wepateni yokunyathela eshushu uthambile kwaye ukhanya, awunamaqamza, intlama, imikrwelo ecacileyo, njl.njl., kwaye imiphetho yepateni yokunyathela eshushu ayinakuba nokubonakala okucacileyo;
2) Kwikhadi elimhlophe nekhadi leglasi, kufuneka kunikwe ingqalelo ekhethekileyo ekukhuseleni iimveliso ezigqityiweyo, kwaye impembelelo yezinto ezahlukeneyo ezimbi ezifana nokuguqulwa kwephepha kufuneka incitshiswe ngexesha lenkqubo yemveliso, nto leyo eya kunceda kakhulu inkqubo egudileyo yokunyathela ngobushushu kunye nokuphuculwa kwezinga lokufaneleka kwemveliso;
3) Umaleko wokuncamathelisa we-aluminiyam eyosiweyo kufuneka ube nokunamathela okuphezulu kakhulu (umaleko wokuncamathelisa okhethekileyo kufuneka wenzelwe iimveliso zepakeji yecuba ukuba kuyimfuneko), kwaye uxinzelelo lomphezulu we-aluminiyam eyosiweyo akufuneki lube ngaphantsi kwe-38mN/m;
4) Ngaphambi kokuba kufakwe i-hot stamping, kuyimfuneko ukukhupha ifilimu yokubeka, kwaye uqinisekise ukuchaneka kwe-hot stamping kunye ne-printing overprint ngokulungelelanisa indawo echanekileyo yepleyiti yokufunxa i-hot stamping;
5) Ngaphambi kokuveliswa ngobuninzi, iimveliso ezishushu ngaphambi kokuprinta kufuneka zivavanywe ukutsalwa kwefilimu. Indlela kukusebenzisa iteyiphu ecacileyo eyi-intshi enye ukutsala ngqo i-aluminium eshushu egxinyiweyo, kwaye kujongwe ukuba kukho umgubo wegolide owelayo, ukunyatheliswa okushushu okungaphelelanga okanye okungakhuselekanga, okunokuthintela inani elikhulu leemveliso zenkunkuma kwinkqubo yokuprinta;
6) Xa usenza ifilimu, qwalasela uluhlu lokwandiswa kwecala elinye, olufanele ukuba luphakathi kwe-0.5mm.
03 Ukubeka iHolographic kwindawo eshushu yokunyathela
Ukunyathela okushushu okubekwe kwi-holographic positioning kunokusetyenziswa kwiiprinti ezineepateni ezichasene neemveliso ezingezizo, nto leyo ephucula kakhulu amandla okulwa neemveliso ezingezizo ezemveliso, kwaye iphucula nomgangatho weemveliso. Ukunyathela okushushu okubekwe kwi-holographic positioning kufuna ulawulo oluphezulu kakhulu lobushushu, uxinzelelo kunye nesantya, kwaye imodeli yokunyathela okushushu nayo inempembelelo enkulu kwisiphumo sayo.
Kwi-holographic positioning hot stamping, ukuchaneka kwe-overprint kunxulumene ngqo nomgangatho wemveliso. Ifilimu yokunyathela eshushu kufuneka incitshiswe kwaye yandiswe nge-0.5mm kwelinye icala. Ngokubanzi, i-holographic positioning hot stamping isebenzisa i-hot stamping engenanto. Ukongeza, i-cursor yezinto zokunyathela ezishushu ze-holographic positioning kufuneka zifane, kwaye ipateni kufuneka ibekwe ngokulinganayo, ukuze umatshini akwazi ukulandelela ngokuchanekileyo i-hot stamping cursor.
04 Ezinye iindlela zokuzikhusela:
1) I-aluminiyam efanelekileyo ene-anodized kufuneka ikhethwe ngokohlobo lwe-substrate. Xa unyathela ngobushushu, kufuneka ube nolwazi lobushushu, uxinzelelo kunye nesantya sokunyathela ngobushushu, kwaye uziphathe ngokwahlukileyo ngokwezixhobo ezahlukeneyo zokunyathela ngobushushu kunye neendawo.
2) Iphepha, i-inki (ingakumbi i-inki emnyama), ioyile eyomileyo, i-composite adhesive, njl.njl. ezineempawu ezifanelekileyo kufuneka zikhethwe. Iindawo zokunyathela ezishushu mazigcinwe zomile ukuze kuthintelwe ukubola okanye ukonakala komaleko wokunyathela oshushu.
3) Ngokubanzi, iinkcukacha ze-aluminiyam eyosiweyo yi-0.64m × Iroli enye eyi-120m, ibhokisi enye kwiroli nganye ezili-10; Iiroli ezinkulu ezinobubanzi obuyi-0.64m, ubude obuyi-240m okanye i-360m okanye ezinye iinkcukacha ezikhethekileyo zinokwenziwa ngokwezifiso.
4) Ngexesha lokugcina, i-aluminiyam eyosiweyo kufuneka ikhuselwe kuxinzelelo, kumswakama, kubushushu naselangeni, ize ibekwe kwindawo epholileyo nengena umoya.
