Imboni yokupakisha incike kakhulu ezindleleni zokuphrinta zokuhlobisa kanye namabhodlela omkhiqizo neziqukathi.Kodwa-ke, ukuphrinta engilazini ngokumelene nepulasitiki kudinga amasu ahluke kakhulu ngenxa yezakhiwo eziyingqayizivele kanye nezinqubo zokukhiqiza zento ngayinye.
Ukuphrinta Kumabhodlela Engilazi
Amabhodlela e-Glass akhiqizwa ngokuyinhloko kusetshenziswa inqubo yokubumba i-blow, laphoingilazi encibilikisiwe iphephethwa futhi ivuthelwe ibe yisikhunta ukwenza isimo sesitsha.Lokhu kukhiqizwa kwezinga lokushisa eliphezulu kwenza ukuphrinta kwesikrini kube indlela yokuhlobisa evamile yengilazi.
Ukuphrinta isikrini kusebenzisa isikrini semeshi esihle esiqukethe umklamo wobuciko obekwa ngqo ebhodleleni lengilazi.Uyinki ube esempintsha ezindaweni ezivulekile zesikrini, adlulisele isithombe endaweni engilazi.Lokhu kudala ifilimu ye-inki ephakanyisiwe eyoma ngokushesha emazingeni okushisa aphezulu.Ukuphrinta kwesikrini kuvumela ukukhiqizwa kwesithombe esicacile, esicacile engilazini kanye nebhondi kayinki kahle nendawo eshelelayo.
Inqubo yokuhlobisa ibhodlela lengilazi ivame ukwenzeka lapho amabhodlela asashisa kusukela ekukhiqizeni, okwenza ama-inks ahlangane futhi aphulukise ngokushesha.Lokhu kubizwa ngokuthi "i-hot stamping".Amabhodlela aphrintiwe afakwa kuhhavini afakwa kuhhavini ukuze aphole kancane kancane futhi avimbele ukuphuka ekushaqekeni okushisayo.
Amanye amasu okunyathelisa ingilazi ahlanganisaUmhlobiso wengilazi eshisiwe kanye ne-UV-cured glass printing.Ngokuqhunyiswa komlilo, ama-ink e-ceramic frit aphrintwa isikrini noma asetshenziswe njengama-decals ngaphambi kokuba amabhodlela afakwe eziko lokushisa eliphezulu.Ukushisa okwedlulele kusetha i-pigmented glass frit endaweni unomphela.Ukwelapha nge-UV, oyinki abazwela i-UV baphrintwa isikrini futhi belapheka ngokushesha ngaphansi kokukhanya okunamandla kwe-ultraviolet.
Ukuphrinta Kumabhodlela Epulasitiki
Ngokungafani nengilazi,amabhodlela epulasitiki enziwa ngokubunjwa kwe-extrusion blow, ukubumba i-injection blow, noma ukubunjwa kwe-stretch blow emazingeni okushisa aphansi.Ngenxa yalokho, amapulasitiki anezidingo ezahlukene zokunamathela kweyinki nezindlela zokuphulukisa.
Ukuphrinta kwe-Flexographic kuvame ukusetshenziselwa ukuhlobisa ibhodlela lepulasitiki.Le ndlela isebenzisa isithombe esiphakanyisiwe epuleti le-photopolymer eliguquguqukayo elizungezayo futhi lixhumane ne-substrate.Oyinki abawuketshezi bathathwa yipuleti, badluliselwe ngqo endaweni yebhodlela, bese belapheka ngokushesha nge-UV noma ukukhanya kwe-infrared.
Ukuphrinta kwe-Flexographic kuhamba kahle ekuphrinteni ezindaweni ezigobile, ezijijekile zamabhodlela epulasitiki neziqukathi.Amapuleti aguquguqukayo avumela ukudluliswa kwesithombe okungaguquki ezintweni ezifana ne-polyethylene terephthalate (PET), i-polypropylene (PP), kanye ne-high-density polyethylene (HDPE).Oyinki be-Flexographic bahlangana kahle ne-non-porous plastic substrates.
Ezinye izinketho zokuphrinta zepulasitiki zifaka ukuphrinta kwe-rotogravure nokulebula okunamathelayo.I-Rotogravure isebenzisa isilinda sensimbi esiqoshiwe ukuze idlulisele uyinki ezintweni.Isebenza kahle ekugijimeni kwebhodlela lepulasitiki levolumu ephezulu.Amalebula anikeza ukuguquguquka okwengeziwe kokuhlotshiswa kweziqukathi zepulasitiki, okuvumela imifanekiso enemininingwane, indlela yokwenza, nemiphumela ekhethekile.
Ukukhetha phakathi kwengilazi ngokumelene nokufakwa kwepulasitiki kunethonya elikhulu ezindleleni ezitholakalayo zokunyathelisa.Ngolwazi lwezakhiwo zento ngayinye nezindlela zokukhiqiza, abahlobisi bamabhodlela bangasebenzisa inqubo yokuphrinta efanele ukuze bathole imiklamo yephakheji ehlala isikhathi eside, edonsa amehlo.
Ukuthuthuka okuqhubekayo ekukhiqizeni izitsha zengilazi neziqukathi zepulasitiki kanye nentuthuko yobuchwepheshe bokuphrinta kuzothuthukisa amathuba okupakisha.
