Isingeniso: Ngokuthuthuka okuqhubekayo kwemibono yokusetshenziswa kwabathengi, imikhiqizo eyenzelwe wena uqobo iya ngokuya ithandwa kakhulu phakathi kwabathengi. Ubuchwepheshe bokudlulisa amanzi budlula umkhawulo wobuso obungalingani ongenakunyatheliswa ngokunyathelisa okuyisicaba. Ngemva kokunyathelisa kokudlulisa amanzi, umkhiqizo unezinga eliphezulu lokulingisa, futhi ukwengezwa komkhiqizo wawo kuye kwaphindwa kabili, futhi ukunyathelisa kokudlulisa okwenziwe wena uqobo nakho kuhlangabezana ngokugcwele nezidingo zabathengi zabantu banamuhla. Lesi sihloko sipakishwe yiiphakheji yothingo lwaseShanghai, futhi ngizokwabelana nawe ngezinto eziningana ezithinta ukushintsha kombala kwesikrini sikasilika.
Ubuchwepheshe bokudlulisa amanzi luhlobo lokuphrinta olusebenzisa umfutho wamanzi ukuze lufake i-hydrolyze iphepha/ifilimu yokudlulisa ngemibala. Inzuzo yalo enkulu yobuchwepheshe ukuthi aludingi imishini ekhethekile, alunqunyelwe yimidiya, aludingi izinto ezikhethekile ezisetshenziswayo, futhi aludingi ukushisa okuphezulu, inqobo nje uma kukhona ithuluzi lokufaka isithombe (isikena noma ikhamera yedijithali), ithuluzi lokudweba (ikhompyutha), ithuluzi lokukhipha isithombe (iphrinta ye-inkjet), kanye ne-inki yokudlulisa amanzi, iphepha lokudlulisa amanzi, ungaphrinta noma yisiphi isithombe kunoma iyiphi into eqinile nanoma iyiphi indawo egobile.
Ukudluliselwa kwe-watermark
Ukudluliselwa kophawu lwamanzi kuyinqubo yokudlulisa ngokuphelele ihluzo nombhalo osephepheni lokudlulisa uye ebusweni be-substrate. Kufana kakhulu nenqubo yokudlulisa ukushisa, ngaphandle kokuthi ingcindezi yokudlulisa incike ekucindezelweni kwamanzi. Kuwubuchwepheshe bokudlulisa amanzi obudumile muva nje. Indawo encane yolwazi lwezithombe ingadluliselwa ebusweni be-substrate, okufana nomphumela wokuphrinta wenqubo yokuphrinta iphedi, kodwa izindleko zokutshala imali ziphansi, inqubo yokukhiqiza ilula kakhulu, futhi ithandwa kakhulu ngabasebenzisi. Inqubo yokudlulisa uphawu lwamanzi ayidingi ukwenziwa yi-activator, igwema ukungcola kwezinyibilikisi eziphilayo, futhi inezinzuzo ezisobala ekukhiqizweni kwemisebenzi yezandla nemihlobiso.
01 Ukuhlukaniswa
Ukudluliselwa kokumbozwa kwamanzi
Lokhu okubizwa ngokuthi ukudluliselwa kokugqoka ngamanzi ukuhlobisa lonke ubuso bento, ukumboza ubuso bokuqala bento yokusebenza, nokukwazi ukuphrinta amaphethini ebusweni bonke (obunobukhulu obuthathu) bento. Lokhu kuyinzuzo yayo; kodwa ububi busobala futhi, okungukuthi, ukuguquguquka. Lapho isithwali sezithombe sithintana ngokuphelele ne-substrate, akunakugwenywa ukuthi sizokwelulwa futhi siguquguquke. Ngakho-ke, empeleni, kunzima ukuthi isithombe sidluliselwe ebusweni bento ukuze sifinyelele izinga lokuthembeka.
Iningi lemidwebo nemibhalo ephrintiwe yephepha lokudlulisa amanzi elisetshenziselwa ukudlulisa lakhiwe ngamabhulokhi ombala weyinki ohlotshisiwe kanye namaphethini aphindaphindwayo alula, futhi asikho isidingo sokusebenzisa ifilimu encane ezwela ukukhanya ukuze kunyatheliswe; amafilimu okudlulisa amanzi enziwe kakhulu ngokwelula. Enziwe ngefilimu enhle encibilikayo emanzini. Ifilimu yokudlulisa esetshenziselwa ukudlulisa okunezinhlangothi ezintathu kunzima ukuyidlulisa nokukopisha umbhalo omncane nezithombe ezilandelanayo.
02 Ukudlulisa izinto
Isisekelo sokudlulisa amanzi
I-substrate yokudlulisa amanzi ingaba ifilimu yepulasitiki noma iphepha lokudlulisa amanzi. Imikhiqizo eminingi kunzima ukuyiphrinta ngqo. Ungaphrinta imidwebo nombhalo ku-substrate yokudlulisa amanzi ngokusebenzisa ubuchwepheshe bokuphrinta obuvuthiwe, bese udlulisela imidwebo ku-substrate. Izinto.
1) Ifilimu yokudonsa amanzi egobile enobukhulu obuthathu
Ifilimu yokudonsa amanzi iphrintwa ebusweni befilimu yotshwala ye-polyvinyl encibilikayo emanzini kusetshenziswa inqubo yokuphrinta yendabuko yokudonsa. Inesivinini esikhulu sokwelula futhi kulula ukumboza ubuso bento ukuze kufezwe ukudluliselwa okunezinhlangothi ezintathu. Ububi ukuthi enkambisweni yokumboza, ngenxa yokuguquguquka okukhulu kwe-substrate, ihluzo nombhalo kulula ukuwohloka. Ngenxa yalesi sizathu, izithombe nemibhalo ngokuvamile yakhelwe njengamaphethini aqhubekayo, noma ngabe ukudluliselwa kokukhubazeka, umphumela wokubuka ngeke uthinteke. Ngesikhathi esifanayo, ifilimu yokumboza amanzi yokudonsa isebenzisa i-inki yokudlulisa amanzi. Uma kuqhathaniswa noyinki bendabuko, uyinki yokuphrinta yokudlulisa amanzi inokumelana okuhle kwamanzi, kanti indlela yokomisa iwukomisa kokuguquguquka.
2) Iphepha lokudlulisa uphawu lwamanzi
Izinto eziyisisekelo zephepha lokudlulisa uphawu lwamanzi ziyiphepha elikhethekile. Izinto eziyisisekelo kumele zibe nekhwalithi ezinzile, usayizi onembile, zivumelane nezimo eziqinile endaweni yokuphrinta, izinga lokunwebeka elincane kakhulu, akulula ukuzigoqa nokuziguqula, kulula ukuziphrinta nombala, futhi ungqimba lokunamathela olungaphezulu lumbozwe ngokulinganayo. Izici ezifana nesivinini sokuphelelwa amanzi ngokushesha. Ngokwesakhiwo, akukho mehluko omkhulu phakathi kwephepha lokudlulisa amanzi nefilimu yokudlulisa uqweqwe lwamanzi, kodwa inqubo yokukhiqiza ihlukile kakhulu. Ngokuvamile, iphepha lokudlulisa uphawu lwamanzi lisetshenziselwa ukukhiqiza ihluzo zokudlulisa nombhalo ebusweni be-substrate ngokuphrinta kwesikrini noma ukuphrinta kwe-offset. Indlela yokukhiqiza ethandwa kakhulu ukusebenzisa amaphrinta e-inkjet ukwenza iphepha lokudlulisa uphawu lwamanzi. Kulula ukwenza ihluzo nemibhalo eyenzelwe wena ngokwezintandokazi zakho.
Isiqalisi
I-activator iyi-solvent exubile ephilayo engancibilikisa futhi ibhubhise ifilimu yotshwala be-polyvinyl, kodwa ngeke ilimaze ungqimba lokuphrinta olunezithombe. Ngemva kokuba i-activator isebenza kungqimba lokuphrinta olunezithombe, ingalusebenzisa futhi iluhlukanise nefilimu yotshwala be-polyvinyl. Ifakwe ebusweni be-substrate ukuze kufezwe ukumbozwa kokudluliselwa kwamanzi.
ukugqoka
Ngenxa yokuthi ungqimba oluphrintiwe lwefilimu embozwe ngamanzi lunobunzima obuphansi futhi luklwebheka kalula, ingxenye yokusebenza ngemva kokudluliselwa embozwe ngamanzi kumele ifuthwe ngopende obonakalayo ukuze ivikeleke, ngaleyo ndlela ithuthukise umphumela wokuhlobisa. Ukusetshenziswa kwe-PV transparent varnish noma i-UV light curing transparent varnish coating kungakha umphumela ongabonakali noma wesibuko.
