Isingeniso: Ngokuthuthuka okuqhubekayo kwemiqondo yokusetshenziswa kwabathengi, imikhiqizo eyenziwe ngezifiso iya ngokuya iduma kubathengi. Ubuchwepheshe bokudluliswa kwamanzi bunqamula umkhawulo wendawo engalingani ongakwazi ukuphrinta ngokuphrinta okuyisicaba. Ngemva kokunyathelisa ukudluliswa kwamanzi, umkhiqizo unezinga eliphezulu lokulingisa, futhi ukufakwa komkhiqizo wawo kuphindwe kabili, futhi ukuphrinta kokudlulisa komuntu siqu nakho kuhlangabezana ngokugcwele nezidingo zabathengi zabantu banamuhla.Lesi sihloko sihlanganiswe nguiphakethe le-shanghai rainbow, futhi ngizokwabelana nawe ngezinto ezimbalwa ezithinta ukushintsha kombala kwesikrini sikasilika.
Ubuchwepheshe bokudluliswa kwamanzi kuwuhlobo lokunyathelisa olusebenzisa ukucindezela kwamanzi ukuze kufakwe amanzi ephepheni lokudlulisa/ifilimu yepulasitiki enamaphethini ombala. Inzuzo yayo enkulu yezobuchwepheshe yukuthi ayidingi imishini ekhethekile, ayinqunyelwe ngabezindaba, ayidingi izinto ezisetshenziswayo ezikhethekile, futhi ayidingi ukushisa okuphezulu, inqobo nje uma kukhona ithuluzi lokufaka isithombe (isithwebuli noma ikhamera yedijithali), umdwebo. ithuluzi (ikhompyutha), ithuluzi lokukhipha isithombe (iphrinta ye-Inkjet), kanye noyinki wokudlulisa amanzi, iphepha lokudlulisa amanzi, ungaphrinta noma yisiphi isithombe kunoma iyiphi into eqinile nanoma iyiphi indawo egobile.
Ukudluliswa kwe-watermark
Ukudlulisa uphawu lwamanzi kuyinqubo yokudlulisa ngokuphelele ihluzo nombhalo ephepheni lokudlulisa ebusweni be-substrate. Ifana kakhulu nenqubo yokudlulisa ukushisa, ngaphandle kokuthi ingcindezi yokudlulisa incike ekucindezelweni kwamanzi. Iwubuchwepheshe bokudluliswa kwamanzi obudumile muva nje. Indawo encane yolwazi lwezithombe ingadluliselwa ebusweni be-substrate, efana nomphumela wokuphrinta wenqubo yokuphrinta iphedi, kodwa izindleko zokutshala izimali ziphansi, inqubo yokukhiqiza ilula, futhi ithandwa kakhulu. nabasebenzisi. Inqubo yokudlulisa uphawu lwamanzi ayidingi ukwenziwa kusebenze yi-activator, igwema ukungcoliswa kwezinyibilikisi eziphilayo, futhi inezinzuzo ezisobala ekukhiqizeni imisebenzi yezandla nemihlobiso.
01 Ukuhlukaniswa
Ukudluliswa kwe-coating yamanzi
Okubizwa ngokuthi ukudluliswa kwe-coating yamanzi ukuhlobisa yonke indawo yento, ukumboza ubuso bokuqala bomsebenzi womsebenzi, futhi ukwazi ukuphrinta amaphethini kuyo yonke indawo (i-three-dimensional) yento. Lokhu kuyinzuzo yayo; kodwa ukonakala nakho kusobala, okungukuthi, ukuguquguquka. Uma isithwali sesithombe sithintana ngokuphelele ne-substrate, akunakugwenywa ukuthi izonwetshwa futhi ikhubazeke. Ngakho-ke, eqinisweni, kunzima ukuthi isithombe sidluliselwe ebusweni bento ukuze kuzuzwe izinga lokwethembeka.
Iningi lezithombe eziphrintiwe kanye nemibhalo yephepha lokudlulisa amanzi elisetshenziselwa ukudluliswa lakhiwe ngamabhulokhi wombala oyinki wokuhlobisa kanye namaphethini aphindaphindayo alula, futhi asikho isidingo sokusebenzisa ifilimu enhle ye-photosensitive ukuze uphrinte; amafilimu okudlulisa amanzi ngokuvamile enziwe nge-stretchable Yenziwe ngefilimu enhle encibilikayo emanzini. Ifilimu yokudlulisa esetshenziselwa ukudluliswa kwezinhlangothi ezintathu kunzima ukudlulisa nokukopisha umbhalo ocolekileyo kanye nezithombe ezilandelanayo.
02Dlulisa impahla
I-substrate yokudlulisa amanzi
I-substrate yokudlulisa amanzi ingaba ifilimu yepulasitiki noma iphepha lokudlulisa amanzi. Imikhiqizo eminingi kunzima ukuyiphrinta ngokuqondile. Ungaphrinta ihluzo nombhalo ku-substrate yokudlulisa amanzi ngobuchwepheshe bokuphrinta obuvuthiwe, bese udlulisela ihluzo ku-substrate. Okubalulekile.
1) Ifilimu ye-drape yamanzi egobile enezinhlangothi ezintathu
Ifilimu ye-drape yamanzi iphrintiwe ebusweni befilimu yotshwala ye-polyvinyl encibilika emanzini kusetshenziswa inqubo yokuphrinta ye-gravure yendabuko. Inezinga eliphakeme kakhulu lokunwebeka futhi kulula ukumboza ubuso bento ukuze kuzuzwe ukudluliswa kwezinhlangothi ezintathu. Okubi ukuthi enqubweni yokumboza, ngenxa yokuguquguquka okukhulu kwe-substrate, ihluzo nombhalo kulula ukuwohloka. Ngenxa yalesi sizathu, izithombe nemibhalo ngokuvamile kwakhiwa njengamaphethini aqhubekayo, ngisho noma ukudlulisa kukhubazekile, umphumela wokubuka ngeke uthinteke. Ngesikhathi esifanayo, ifilimu yokugcoba amanzi e-gravure isebenzisa inki yokudlulisa amanzi. Uma kuqhathaniswa noyinki wendabuko, oyinki bokuphrinta bokudluliswa kwamanzi banokumelana kahle namanzi, futhi indlela yokomisa iwukumisa nge-volatilization.
2) Iphepha lokudlulisa uphawu lwamanzi
Izinto eziyisisekelo zephepha lokudlulisa uphawu lwamanzi yiphepha elikhethekile. Izinto eziyisisekelo kumele zibe nekhwalithi ezinzile, usayizi onembile, ukuguquguquka okuqinile endaweni yokunyathelisa, izinga lokunweba elincane kakhulu, akulula ukugoqa nokuwohloka, kulula ukuphrinta nombala, futhi ungqimba lwe-adhesive ongaphezulu luboshwe ngokulinganayo. Izici ezifana nesivinini sokuphelelwa amanzi emzimbeni. Ngokwesakhiwo, akukho mehluko omkhulu phakathi kwephepha lokudlulisa amanzi kanye nefilimu yokudlulisa imboza yamanzi, kodwa inqubo yokukhiqiza ihluke kakhulu. Ngokuvamile, iphepha lokudlulisa uphawu lwamanzi lisetshenziselwa ukukhiqiza ihluzo zokudlulisa nombhalo ebusweni be-substrate ngokuphrinta isikrini noma ukuphrinta kwe-offset. Indlela yokukhiqiza edume kakhulu ukusebenzisa amaphrinta e-inkjet ukwenza iphepha lokudlulisa uphawu lwamanzi. Kulula ukwenza ihluzo nemibhalo yomuntu siqu ngokuya ngokuthanda kwakho.
I-activator
I-activator iyi-organic mix solvent engancibilika ngokushesha futhi ibhubhise ifilimu yotshwala ye-polyvinyl, kodwa ngeke ilimaze isendlalelo sokuphrinta esiyingcaca. Ngemuva kokuthi isisebenzi sisebenze kungqimba yokuphrinta eyisithombe, singayivula futhi siyihlukanise nefilimu yotshwala ye-polyvinyl. I-Adsorbed ebusweni be-substrate ukuze kuzuzwe ukunamathela kokudluliswa kwamanzi.
enamathela
Ngenxa yokuthi ungqimba oluphrintiwe lwefilimu enamanzi lunobulukhuni obuphansi futhi bushesha kalula, ucezu lomsebenzi ngemva kokudluliswa kwamanzi kufanele lufafazwe ngopende obala ukuze luvikeleke, ngaleyo ndlela uqhubeke uthuthukisa umphumela wokuhlobisa. Ukusetshenziswa kwe-varnish esobala ye-PV noma ukukhanya kwe-UV okuphulukisa i-varnish esobala kungakha umphumela we-matte noma wesibuko.
