Amaphrinta we-UV roll-to-roll baye benza izinguquko embonini yokunyathelisa, baletha ukuphrinta kwekhwalithi ephezulu kuma-substrates ahlukahlukene. Le mishini isebenzisa ukukhanya kwe-ultraviolet ukwelapha oyinki, okuholela emibalabala egqamile namaphrinti ahlala isikhathi eside. Kodwa-ke, njenganoma yibuphi ubuchwepheshe obuthuthukisiwe, bangathola nezinkinga ezithinta ukusebenza nekhwalithi yokuphumayo. Ukuqonda izinkinga ezivamile nezixazululo zazo kungasiza opharetha bagcine ukusebenza kahle futhi baqinisekise imiphumela emihle.
Enye yezinkinga ezivame kakhulu ngemishini yokuphrinta ye-UV roll-to-roll ukupholisa uyinki okwanele. Uma uyinki ungelapheki ngokugcwele, ungabangela ukugcotshwa, ukunganamatheli kahle, kanye nekhwalithi yokuphrinta encishisiwe iyonke. Le nkinga ingabangelwa izici eziningana:
Ukuchayeka kwe-UV okunganele:Qinisekisa ukuthi isibani se-UV sisebenza kahle futhi sisebangeni elifanele ukusuka ku-substrate. Hlola amandla e-UV njalo bese ushintsha isibani se-UV uma kunesidingo.
Iphutha ekwenziweni kukayinki:Ukusebenzisa o-inki abangahambisani nomshini noma i-substrate kungase kubangele izinkinga zokwelapha. Ngaso sonke isikhathi sebenzisa oyinki abanconywe umenzi ukuze uthole imiphumela engcono kakhulu.
Isilungiselelo sesivinini:Uma uphrinta ngokushesha kakhulu, uyinki ungase ungabi naso isikhathi esanele sokwelapha. Lungisa ukulungiselelwa kwesivinini ukuze uqinisekise ukuthi uyinki ululama ngendlela efanele ngaphandle kokuphazamisa ukusebenza kahle kokukhiqiza.
Isihloko sokuphrinta esivalekile kungenye inkinga evamile engaphazamisa inqubo yokuphrinta. Lokhu kungabangela ama-streaks, imibala engekho, noma ukuphrinta okungalingani. Ukuze uxazulule lolu daba, yenza okulandelayo:
Ukunakekela okuvamile:Sungula ishejuli yendlela yokulungisa ehlanganisa ukuhlanza ikhanda lokuphrinta. Sebenzisa izixazululo zokuhlanza ezinconyiwe zomkhiqizi ukuze uvimbele ukunqwabelana.
Hlola i-viscosity kayinki:Qiniseka ukuthi i-viscosity kayinki ingaphakathi kwebanga elinconyiwe. Uma uyinki uwugqinsi kakhulu, kungase kubangele ukuvaleka. Uma kunesidingo, lungisa ifomula ye-inki noma izinga lokushisa.
Ukusetshenziswa kwezihlungi:Faka izihlungi emigqeni yokunikezela ngoyinki ukuze uvimbele udoti ukuthi ungangeni ekhanda lokuphrinta. Hlola futhi ushintshe lezi zihlungi njalo ukuze ugcine ukugeleza okuhle.
Ekuphrinteni kwe-UV roll-to-roll, ukuphatha imidiya kubalulekile. Izinkinga ezifana nokushwabana kwemidiya, ukungaboni ngaso linye, noma izinkinga zokuphakelayo zingaholela ekumoshweni kwempahla nesikhathi. Ukubhekana nalezi zinkinga:
Isilungiselelo esifanelekile se-tension:Qiniseka ukuthi imidiya ilayishwe ukushuba okufanele. Ukushuba kakhulu kuzodala ukuthi abezindaba banwebe, ukucindezeleka okuncane kakhulu kuzoyibangela ukuba ishelele.
Ukuhlola ukuqondanisa:Njalo hlola ukulungiswa kwesiphakeli semidiya. Ukungaqondani kahle kungabangela ukuphrinta okusontekile kanye nokumosha izinto. Lungisa imihlahlandlela yephepha njengoba kudingeka ukuze uqinisekise ukuqondanisa okufanele.
Izimo zemvelo:Gcina indawo yokuphrinta ezinzile. Umswakama ophezulu noma ukushintshashintsha kwezinga lokushisa kungathinta izici zemidiya, kubangele izinkinga zokusebenza. Sebenzisa isistimu yokulawula izinga lokushisa ukuze ugcine indawo ekahle.
Ukuthola umbala ophumayo ongaguquki kubalulekile ekuphrinteni okuphrofeshinali. Ukuhluka kwemibala kungabangelwa izici ezilandelayo:
Ukulinganisa:Linganisa iphrinta yakho njalo ukuze uqinisekise ukunemba kombala. Lokhu kuhlanganisa ukulungisa amaphrofayela ombala nokwenza amaphrinti okuhlola ukuze kuqinisekiswe ukuvumelana.
Ukuhluka kweqoqo likayinki:Umbala kayinki ungahluka kancane kusuka kunqwaba kuya kwenqwaba. Ukuze uthole ukuvumelana, sebenzisa njalo uyinki ovela kuqeqebana elifanayo.
Umehluko we-substrate:Ama-substrates ahlukene amunca uyinki ngendlela ehlukile, okuthinta ukuphuma kombala. Hlola ama-substrates amasha ukuze unqume ukuthi asebenzisana kanjani noyinki osetshenzisiwe.
Ekuphetheni
Imishini yokunyathelisa ye-UV roll-to-roll inamandla futhi, uma igijima kahle, ikhiqiza imiphumela emangalisayo. Ngokuqonda nokuxazulula izinkinga ezivamile njengezinkinga zokuphulukisa ziyinki, ama-printhead clogs, izinkinga zokuphatha imidiya, nokuvumelana kombala, opharetha bangathuthukisa inqubo yabo yokuphrinta futhi bazuze okukhiphayo kwekhwalithi ephezulu. Ukunakekelwa okuvamile, ukusetha okufanele, nokunaka imininingwane kuyisihluthulelo sokuthuthukisa ukusebenza kwale mishini ethuthukisiwe.
