Ibhokisi lephepha umehluko phakathi kwe-UV yokuphrinta i-foil yegolide
Isibonelo, izembozo zezincwadi ziyi-golden foil printing, amabhokisi esipho kukhona ukuphrinta i-foil yegolide, izimpawu zokuthengisa kanyeugwayi amabhokisi, utshwala, nezingubo ziyi-gold foil printing, nokuphrinta ucwecwe lwegolide lwamakhadi emikhonzo, izimemo, amapeni, njll. Imibala namaphethini kungenziwa ngokwezifiso ngokwezidingo ezithile.
Izinto eziyinhloko ezisetshenziselwa ukushaya isitembu esishisayo yi-electrochemical aluminium foil, ngakho-ke ukugxiviza okushisayo kubizwa nangokuthi i-electrochemical aluminium hot stamping; Into eyinhloko edlula ku-UV iyinki equkethe ama-photosensitizer ahlanganiswe namalambu okwelapha e-UV.
1. Umgomo wenqubo
Inqubo yokunyathelisa ye-foil yegolide isebenzisa isimiso sokudlulisa umshini oshisayo ukuze idlulisele ungqimba lwe-aluminium ku-aluminium anodized ebusweni be-substrate ukuze kwakhe umphumela wensimbi okhethekile; Ukwelashwa kwe-UV kufinyelelwa ngokumisa nokwelapha uyinki u ngaphansi kokukhanya kwe-ultraviolet.
2. Izinto eziyinhloko
Inqubo yokuhlobisa yokuphrinta. Shisisa ipuleti lokuphrinta lensimbi, sebenzisa i-foil, bese ucindezela umbhalo osagolide noma amaphethini ezintweni eziphrintiwe. Ngokuthuthuka okusheshayo kwezimboni zokuphrinta zegolide nezokupakisha, ukusetshenziswa kwe-electrochemical aluminium stamping kuya ngokuya kwanda.
I-substrate yokuphrinta i-foil yegolide ihlanganisa iphepha elivamile, iphepha lokunyathelisa eliyinki elifana noyinki wegolide nesiliva, ipulasitiki (PE, PP, PVC, amapulasitiki obunjiniyela afana ne-ABS), isikhumba, ukhuni, nezinye izinto ezikhethekile.
Ukuphrinta kwe-UV kuyinqubo yokuphrinta esebenzisa ukukhanya kwe-ultraviolet ukuze kome futhi kuqiniswe uyinki, edinga inhlanganisela kayinki oqukethe ama-photosensitizer namalambu okwelapha e-UV. Ukusetshenziswa kokuphrinta kwe-UV kungenye yezinto ezibaluleke kakhulu embonini yokuphrinta.
Uyinki we-UV umboze izinkambu ezifana nokuphrinta kwe-offset, ukuphrinta kwesikrini, ukuphrinta kwe-inkjet, nokuphrinta kwephedi. Imboni yokunyathelisa evamile ngokuvamile ibhekisela ku-UV njengenqubo yomphumela wokuphrinta, ehlanganisa ukugoqa ungqimba lwamafutha acwebezelayo (okuhlanganisa amakristalu agqamile, ama-matte, ashumekiwe, impushana ka-anyanisi wegolide, njll.) kuphethini oyifunayo eshidini eliphrintiwe.
Inhloso eyinhloko ukukhulisa ukukhanya nomphumela wobuciko womkhiqizo, ukuvikela ubuso bomkhiqizo, ube nobunzima obuphezulu, ukumelana nokugqwala nokungqubuzana, futhi abajwayele ukuklwebheka. Eminye imikhiqizo ye-lamination manje isishintshelwe ku-UV enamathelayo, engahlangabezana nezidingo zemvelo. Kodwa-ke, imikhiqizo ye-UV akulula ukuyibopha, futhi eminye ingaxazululwa kuphela nge-UV yendawo noma ukupholisha.
