Umhlahlandlela: i-UV glazing yendawo ingaba ngokwezidingo zokucwebezela komkhiqizo, uphawu lokuhweba, ukupakishwa nokuphrinta isidingo sokugqamisa izingxenye ze-glazing yasendaweni, amaphethini acwebezelayo uma kuqhathaniswa namaphethini azungezile avela agqamile, agqamile, umuzwa wezinhlangothi ezintathu, angakhiqiza. umphumela wobuciko oyingqayizivele.Leli phepha lichaza kafushane ulwazi oluhlobene nenqubo yokucwebezela kwe-UV yendawo, okuqukethwe okuyinkomba yabangane:
Inqubo ye-UV glazing yendawo
I-UV yasendaweni, ubuchwepheshe bokuqeda indawo yokuphrinta.Ngenxa yokusebenzisa kwayo i-varnish ye-UV enokukhanya okuphezulu, obala nokumelana nokugqoka ekukhanyeni okukhethiwe kombhalo ophrintiwe nombhalo.Ngenkathi igqamisa itimu yesakhiwo, iphinde ithuthukise umphumela womhlobiso ongaphezulu wemikhiqizo yokuphrinta, esetshenziswa kakhulu kumakhava ezincwadi kanye nomhlobiso wangemuva komshini wemikhiqizo yokupakisha.
1, umphumela we-UV
Njengamanje, umphumela ovamile wendawo we-UV uthi: ukukhanya kwendawo, ukushabalala kwendawo, ukugaya kwendawo, umbala wendawo we-refraction, imibimbi yendawo nezimbali zeqhwa zendawo.
I-UV yasendaweni ingasetshenziswa ngemuva kokufakwa kwe-laminating, kodwa futhi endabeni ephrintiwe ngokuqondile, kodwa ukuze kugqanyiswe umphumela wokucwebezelisa kwendawo.Ngokuvamile, kwenziwa ngemva kokuphrinta, futhi ikakhulukazi embozwe ifilimu ye-matte, ebala cishe ama-80% emikhiqizo yendawo ye-UV ecwebezelayo.
Umehluko omkhulu phakathi kwe-glazing yendawo kanye ne-full version glazing ukuthi enye iyadingeka ukwenza ipuleti lokuphrinta kanti enye iwukuba nezidingo ezithile zokubhalisa zemishini yokucwenga.I-UV glazing yendawo inezici ezintathu, okungukuthi, ipuleti elicwebezelayo, ukubhaliswa kwemishini kanye nemishini yokwelapha.Ukuze uqinisekise ukuthi ingxenye yendawo ecwebezelayo ye-UV ihambisana nosayizi wombhalo ophrintiwe nesithombe, indlela yokuthwebula izithombe ezwelayo kufanele isetshenziswe lapho kwenziwa ipuleti elicwebezelayo.
2, ezihlukanisiwe
Ukuphrinta kwesikrini ukucwebezela kwendawo
Ukuphrinta kwesikrini kunezici zokudlulisa uyinki ophezulu, ungqimba lukayinki owugqinsi kanye nomuzwa oqinile wezinhlangothi ezintathu.Ukucwebezela ngepuleti lesikrini kufanele kukhethwe ngokujwayelekile isikrini semeshi esingu-200 ~ 300 (somphumela wendawo ocwebezelayo we-matte wendawo, inombolo yemeshi iphansi), ukungezwani kwenethiwekhi ngo-20 ~ 25N/ CM.Ngoba ukutshalwa kwezimali kwemishini akukhulu.Izincwadi eziningi nezimboni zokupakisha ekwandeni kwebhizinisi le-glazing lendawo, kukhethwa ukuphrinta kwesikrini.
I-Flexo glazing yendawo
Ukuphrinta kwe-Flexographic kubonakala ngokukwazi ukwenza izimbotshana eziminyene ngenqubo elula.Ngakho-ke, idume kakhulu ekukhanyeni kwe-UV.I-Flexographic glazing yendawo yokuphrinta ihlukaniswe yaba i-flexographic printing glazing kanye ne-flexographic printing glazing ekhethekile, futhi umbhalo othile olula nesithombe zisasebenzisa i-letterpress yenjoloba eqoshiwe.
I-Flexographic printing local glazing ifanele ukucwebezela okungaxhunyiwe ku-inthanethi noma ukucwebezela okuku-inthanethi.Yamukela indlela yokuphrinta ye-flexographic glazing, sebenzisana ne-anilox roller kanye ne-cavity type scraper, ingakwazi ukulawula ngokunembile inani le-glazing, ikhwalithi ye-glazing izinzile.
I-Gravure glazing yendawo
Ukuphrinta kwe-Gravure ngenxa yongqimba lukayinki wokuphrinta kukhulu futhi ukumelana nokuphrinta kwesigubhu se-concave kuphezulu ekucwebezelweni kwe-UV yendawo nakho kunezinzuzo, ikakhulukazi ukuvela komshini wokuphrinta we-gravure ofakwe ngeshidi ukuze kuthuthukiswe ukucwebezela kwendawo kube neqhaza ekuthuthukiseni.Kepha ngenxa yezindleko zayo eziphakeme ze-seihan zisetshenziswa kakhulu ebhizinisini le-glazing ende.
Ezinye izindlela ze-glazing zendawo
Ngaphambi kokufika kwe-varnish ye-UV, akekho owayengasebenzisa ukuphrinta kwe-offset ukuze kucwebezeliswe ngoba ungqimba lukayinki wokuphrinta luncane kakhulu.Futhi ivanishi ye-UV ngenxa yefilimu ewugqinsi, isicwebezelisi esiphezulu futhi inenzuzo yokunemba okuphezulu kokuphrinta okweqile ekucwebezelweni kwe-UV yasendaweni nayo inezinhlelo ezithile kodwa ezisetshenziselwa ukucwebezela ku-inthanethi.
Kusukela kumodi yokukhiqiza, umshini wendawo ocwebezelayo we-UV ungabuye uhlukaniswe ngokucwebezelisa okungaxhunyiwe ku-inthanethi nokucwebezelisa okuku-inthanethi.Ukukhanya okungaxhunyiwe ku-inthanethi kubhekisela ekuphrinteni, ukucwebezela emishinini ekhethekile, ngokulandelana, isidingo sokusebenzisa umshini okhethekile wokucwebezelisa noma i-calender.Ukucwebezela okungaxhunyiwe ku-inthanethi, ngenxa yokuthi into ephrintiwe ingomiswa ngokuphelele, ngakho-ke ingathola ukucwebezela okuphezulu kunokucwebezela okuku-inthanethi.Ngaphezu kwalokho, ukuguquguquka kokukhiqizwa kwe-glazing okungaxhunyiwe ku-inthanethi.
Ukutshalwa kwezimali okuncane kumishini.Ukucwebezelisa okuku-inthanethi kubhekisela ekunyatheliseni nasekucwebezeni okwenziwa emugqeni owodwa wokukhiqiza, okungukuthi, ukungeza izinto ezicwebezelayo nezicwebezelayo ze-UV emshinini wokunyathelisa.Ukubangela ukuthi indaba ephrintiwe ipholishwe ngqo ngemva kokuphrinta.
Ubuchwepheshe obusha bendawo be-UV
①Ubuchwepheshe bukayinki obuxubile
Ngenxa yokuthi ukuphrinta kwe-UV noma ukucwebezela kwe-UV akufanelekile ukusetshenziswa endaweni ebambayo eqinile engaphansi, futhi abampofu phezu kokunamathela kukayinki wokuphrinta, ngakho-ke isidingo esiningi sokucwebezela kwe-UV eku-inthanethi, uma bonke sisebenzisa uyinki wokuphrinta we-UV, siboshiwe. ukwandisa izindleko: uma usebenzisa ukuphrinta kwe-inki okuvamile, ukudalwa kwe-glazing ehlanganisiwe noma ebanzi, okungangabazeki ukuthi kuvimbele ukusetshenziswa kwe-offset printing glazing online.
Ubuchwepheshe be-inki obuxubile busebenza kahle ukuxazulula le nkinga yebhodlela.Ihlanganisa izinzuzo zikayinki we-UV kanye noyinki wendabuko ngokusebenza, okungukuthi, izinzuzo zokuphulukisa ukukhanya nokomisa i-polymerization nge-oxidation, ithuthukisa umphumela we-synergistic we-ink surface kanye ne-varnish ye-UV, futhi ivula indlela yokuphrinta kwe-offset ekucwebezeni komugqa.
② i-glazing ehlehlayo
I-Pro-cure ihlobene nokucwebezela kwendabuko kwendawo.Thatha indlela evamile yokucwebezela (ukuphrinta kwesikrini sokuphrinta se-flexographic noma ukuphrinta kwe-gravure) ukuze kucwebezeliswe kwasendaweni, ekugcineni kufanele kusetshenziswe ukuphrinta kwepuleti elicwebezelayo lendawo, ukuze kuzuzwe umphumela ophezulu wokungafani wombhalo wendawo nesithombe, ngakho ukucwebezela nokuphrinta ukunemba kokuphrinta kuyisihluthulelo. kunqubo ye-glazing.Inqubo ye-glazing ehlehlayo iphula imithetho engenhla, ukuze inkinga yokubhalisa ixazululwe.
③Ukukhanya kwe-UV okuku-inthanethi
I-Online glazing yokuphrinta i-flexographic nokuphrinta i-gravure, akuzange kuthiwe ubuchwepheshe obusha, futhi ngenxa yohlu olubanzi lwezinhlelo zokusebenza, ukunemba kokuphrinta kanye nokuphrinta kwe-offset ngesivinini esikhulu, kusekuhlukaniseni kanye nezinsizakalo ezengeziwe ze-value ezethulwe ngemibono emisha yokucwenga. ubuchwepheshe.
Kunezinhlobo ezine eziyinhloko zokukhanyisa kwe-UV okuku-inthanethi ezisetshenzisiwe:
Ukukhanya kwe-UV + ukukhanya kwe-UV;
Uyinki oxubile + Ukukhanya kwe-UV;
Uyinki we-UV + uwoyela we-OP + Ukukhanya kwe-UV (ukucwebezela okuphambene);
Uyinki ojwayelekile + ukucwebezela okuphindwe kabili (ukucwebezela emanzini + ukucwebezela kwe-UV).
3. Izindaba ezidinga ukunakwa
1) Izidingo zokuphrinta izithasiselo zeyinki.
Uma i-UV glazing yendawo ingaphezulu kwemikhiqizo yokuphrinta, uyinki wokuphrinta akufanele wengeze noma wengeze izithasiselo ezihlukahlukene kancane ngangokunokwenzeka, njenge-ejenti yokususa i-adhesive, uwoyela uyinki, ukuze ungaphazamisi i-polarity yangaphezulu. ungqimba lukayinki, okuholela ekubeni uwoyela wesikhathi sokukhanya kanye nokunamathela kongqimba lukayinki ukushesha kokunamathela kumpofu, ungqimba lukawoyela olula kulula ukuwa, ukuze kuthinte kakhulu umphumela wokucwebezela.
2) Izidingo zokuphrinta impuphu yokufafaza.
Inani lokufafaza okuyimpuphu liyadingeka ukuze libe lincane.Inani elikhulu lokufafaza kwe-powder lizokwenza ungqimba lwempuphu ebusweni bendaba yokunyathelisa, okuholela ekutheni ungqimba lwamafutha we-UV lungakwazi ukunamathela ngokuqinile kungqimba lukayinki, kulula ukuwa, lubonisa ucezu lwenkungu yefu, ethinta kakhulu umphumela we-glazing.Uma inani lempushana lingalawulwa kahle ngesikhathi sokunyathelisa, impushana kufanele isuswe ngokuhlikihlwa ngesandla uma kunesidingo.
3) Izidingo zokungezwani komhlaba kwemikhiqizo eboshwe.
Ngesidingo semikhiqizo ye-UV glazing yendawo ngemuva kokumbozwa, kungcono ukusebenzisa izinhlangothi zombili zefilimu ngemuva kokwelashwa kwe-corona, okungukuthi, ukungezwani okungaphezulu ezinhlangothini zombili zefilimu ukuze kufinyelele ngaphezu kuka-38Mn / m, ukuze kuqinisekiswe ukuthi I-varnish ye-UV ingaxhunyaniswa ngokuqinile nefilimu.Ngesikhathi esifanayo, hlola ifilimu esetshenzisiwe.
