Ngokusetshenziswa kwezinto zokuphrinta ezingamunceki njengekhadibhodi yegolide nesiliva kanye nephepha lokudlulisa i-laser kumaphakheji kagwayi, ubuchwepheshe bokuphrinta be-UV offset bubuye busetshenziswe kabanzi ekunyatheliseni iphakheji likagwayi.Kodwa-ke, ukulawulwa kwenqubo yokuphrinta ye-UV offset nakho kunzima, futhi izinkinga eziningi zekhwalithi zingenzeka kalula kunqubo yokukhiqiza.
I-ink roller glaze
Enqubweni yokuphrinta kwe-UV offset, into ecwebezelayo ecwebezelayo izokwenzeka lapho irola likayinki ligijima ngesivinini esikhulu isikhathi eside, okuholela ekufakweni okungalungile, futhi ibhalansi kayinki namanzi kunzima ukuqinisekiswa.
Kutholakala ekukhiqizweni kwangempela ukuthi iqoqo lamarola ayinki amasha ngeke akhiqize ukucwebezela okucwebezelayo enyangeni yokuqala yokusetshenziswa, ngakho ukucwilisa amarola ayinki kurola oyinki wokunciphisa unama amahora angama-4 kuye kwayi-5 njalo ngenyanga kungabuyisa ukusebenza kwe-inki. amarola ayinki, ngaleyo ndlela anciphise ukukhiqizwa kokucwebezela okucwebezelayo kwamarola ayinki.
Ukunwetshwa kwerola likayinki
Njengoba sonke sazi, uyinki we-UV ugqwala kakhulu, ngakho-ke irola likayinki elizungezwe uyinki we-UV offset nalo lizokhula.
Lapho i-roller eyinki ikhula, izinyathelo zokwelashwa ezifanele kufanele zithathwe ngesikhathi ukuze kugwenywe imiphumela emibi.Into ebaluleke kakhulu ukuvimbela ukunwetshwa ekubangeleni ukucindezela ngokweqile ku-roller kayinki, ngaphandle kwalokho kuzodala amabhamuza, ukuphuka kwejeli nezinye izenzakalo, futhi kubangele nomonakalo obulalayo kumishini yokunyathelisa ye-UV offset ezimeni ezibucayi.
Ukuphrinta okungamanga
Ukunemba kokuphrinta ekuphrinteni kwe-UV offset kwamaphakethe kagwayi kungahlukaniswa kube lezi zinhlobo ezimbili ezilandelayo.
(1) Ukuphrinta kwedekhi yombala wokwelapha we-UV akuqinile.
Kulokhu, ukulandelana kombala kufanele kuhlelwe ngokunengqondo, futhi isibani se-UV phakathi kwamadekhi ombala kufanele sigwenywe ngangokunokwenzeka.Ngokuvamile, ungqimba lukayinki omhlophe wokuphrinta kokuqala luyaqina futhi ukuphulukiswa kwe-UV kuyenziwa;Uma uphrinta uyinki omhlophe okwesibili, ungqimba lukayinki luzoncishiswa ngaphandle kokwelashwa kwe-UV.Ngemuva kokuphrinta ngokweqile namanye amadekhi ombala, umphumela oyisicaba nawo ungafinyelelwa.
(2) Indawo enkulu yokunyathelisa ensimini ayilona iqiniso.
Kunezici eziningi ezithinta indawo enkulu yokunyathelisa ensimini.Ukuze ugweme indawo enkulu yokunyathelisa ensimini, qala uhlole ukuthi ukucindezela kwe-inki roller kulungile yini ukuze uqinisekise ukuthi i-roller eyinki ayinakho ukucwebezela;Qinisekisa ukuthi amapharamitha enqubo yesixazululo somthombo alungile;Ubuso bengubo ngeke bube nokungcola, izimbobo, njll. Ngaphezu kwalokho, ukuhlolwa kuye kwafakazela ukuthi ukucindezelwa komoya kweqembu ngemva kokunyathelisa kwensimu yendawo enkulu kuzoba nomphumela osheshayo ekuthuthukiseni ukuvuleka kokunyathelisa kwensimu enkulu.
Ukudonsela emuva kukayinki
Ekuphrinteni kwe-UV offset, ukudonsa uyinki emuva kuwukwehluleka okuvamile, ikakhulukazi ngenxa yokuthi uyinki yokuphrinta ye-UV ayelapheki ngokugcwele ngemva kokushiswa kwemisebe ye-UV, futhi ayinamathiselwe ngokuqinile ku-substrate.Ngaphansi komthelela wengcindezi yokuphrinta yamadekhi ombala alandelayo, uyinki uyadonselwa phezulu futhi unamathele engubeni yezinye izitezi ezinemibala.
Uma ukudonswa kwe-inki emuva kwenzeka, ngokuvamile kungaxazululwa ngokunciphisa okuqukethwe kwamanzi eqembu le-UV lokwelapha lombala, ukwandisa okuqukethwe kwamanzi eqembu lombala wokudweba uyinki, nokunciphisa ingcindezi yokuphrinta yeqembu lomdwebo we-inki;Uma inkinga isengakaxazululeki, yelapha nge-UV
Le nkinga ingathuthukiswa ngokungeza inani elifanele le-ejenti eqinile kuyinki wedekhi yombala.Ngaphezu kwalokho, ukuguga kwengubo yenjoloba futhi kuyisizathu esibalulekile se-ink back pull phenomenon.
Ukuphrinta ibhakhodi embi
Ngokuphrinta kwe-UV offset yamaphakheji kagwayi, ikhwalithi yokuphrinta ibhakhodi iyinkomba ebalulekile.Ngaphezu kwalokho, ngenxa yokukhanya okuqinile kwekhadibhodi yegolide nesiliva, kulula ukubangela ukutholwa kwekhodi yebha ukuthi ingazinzi noma ingabi sezingeni.Ngokuvamile, kunezimo ezimbili eziyinhloko lapho ibhakhodi ye-UV yephakeji kagwayi yehluleka ukuhlangabezana nezinga elijwayelekile: idigri yesici kanye nedigri yokukhipha amakhodi.Uma idigri yesici ingekho ezingeni elifanele, hlola ukuthi ingabe ukuphrinta kukayinki omhlophe kusicaba kanye nokuthi iphepha limbozwe ngokuphelele yini;Uma ukukhishwa kwekhodi kungekho ezingeni elifanele, hlola ukufakwa kwe-inki kwedekhi yombala wokuphrinta ibhakhodi nokuthi ibhakhodi ine-ghosting.
Oyinki bokuphrinta be-UV offset abanezigaba ezihlukene zombala banokudlulisela okuhlukile ku-UV.Ngokuvamile, i-UV kulula ukungena kumayinki wokuphrinta we-UV aphuzi kanye ne-magenta, kodwa kunzima ukungena oyinki bokuphrinta be-Cyan nomnyama we-UV we-UV, ikakhulukazi oinki bokuphrinta be-UV offset abamnyama.Ngakho-ke, ekushicileleni kwe-UV offset, uma ubukhulu bukayinki omnyama we-UV offset bukhushulwa ukuze kuthuthukiswe umphumela wokuphrinta webhakhodi, kuzophumela ekomisweni kabi kukayinki, ukunamathela kabi kongqimba lukayinki, ukuwa kalula, ngisho nokubi. ukunamathela.
Ngakho-ke, kufanele kuqashelwe ngokukhethekile ubukhulu bongqimba lukayinki omnyama ekuphrinteni kwe-UV offset ukuvimbela ibhakhodi ukuthi inganamatheli.
Isitoreji sikayinki wokuphrinta we-UV offset
Uyinki wokuphrinta we-UV offset kufanele ugcinwe endaweni emnyama engaphansi kuka-25 ℃.Uma igcinwe ezingeni lokushisa eliphezulu, uyinki yokuphrinta ye-UV offset izoqina futhi ibe lukhuni.Ikakhulukazi, i-UV offset yegolide nesiliva uyinki ijwayele ukuqiniswa futhi isicwebezelisi esingesihle kunoyinki ojwayelekile we-UV offset, ngakho-ke kungcono ukungawugcini isikhathi eside.
Kafushane, inqubo yokuphrinta ye-UV offset inzima ukuyiqonda.Ochwepheshe bamabhizinisi okuphrinta iphakheji likagwayi kumele babheke ngokucophelela futhi bafingqe ekukhiqizeni kokuphrinta.Ngokwesisekelo sokuthola ulwazi oludingekayo lwethiyori, ukuhlanganisa ithiyori nolwazi kusiza kakhulu ekuxazululeni izinkinga okuhlangatshezwane nazo ekunyatheliseni kwe-UV offset.
