Ekuphrinteni nge-inkjet, ukusetshenziswa kwezibani zokupholisa ze-UV LED kuzuzise kakhulu ngenxa yokusebenza kahle kwazo kanye nempumelelo ekwelapheni oyinki. Kodwa-ke, ukuze kuqinisekiswe ukuphulukiswa okuphelele, kubalulekile ukuthi ukuqina kwe-UV yesibani se-UV kuhlolwe njalo. Lo mkhuba ubalulekile ukuze kuqinisekiswe ikhwalithi nokuvumelana kwenqubo yokwelapha ngesikhathi sokuphrinta.
Izibani ze-UV LED zokuphulukisaasetshenziswa kakhulu embonini yokunyathelisa ukuze akwazi ukwelapha ngokushesha oyinki nama-coatings, okuholela ezikhathini zokukhiqiza ezisheshayo kanye nekhwalithi yokuphrinta ethuthukisiwe. Lezi zibani zikhipha ukukhanya kwe-ultraviolet, okuqalisa ukusabela kwe-photochemical ku-inki, okubangela ukuba ukwelapha nokunamathela ku-substrate. Kodwa-ke, ukuphumelela kwenqubo yokwelapha kuncike ngokuqondile ekuqineni kwe-UV okukhishwa isibani.
Esinye sezizathu eziyinhloko zokuthi kungani ukuphulukiswa kwe-inki kudinga ukuhlolwa kokuqina kwesibani se-UV ukuthi kungenzeka ukucekelwa phansi ngokuhamba kwesikhathi. Amalambu e-UV e-UV athola ukwehla kancane kancane kokuphumayo kwe-UV njengoba ekhula, okungaba nomthelela omkhulu ekwelapheni ukusebenza. Ngokuqapha njalo ukushuba kwe-UV, amaphrinta angakwazi ukuhlonza noma yikuphi ukwehla kokukhiphayo futhi athathe izinyathelo ezisebenzayo ukuze agcine ukusebenza kahle kwesibani.
Ngaphezu kwalokho, ukuhlukahluka kokuqina kwe-UV kungenzeka ngenxa yezici ezifana nezinga lokushisa, umswakama nezimo zokusebenza. Lokhu kuhlukahluka kungathinta inqubo yokwelapha, okuholela ekushintshaneni kwekhwalithi yokuphrinta nokunamathela. Ngokugada ukushuba kwe-UV, amaphrinta angenza izinguquko ukuze aqinisekise ukuthi izimo zokuphulukisa zihlala zilungile, avimbele izinkinga ezingaba khona ngokunamathela kukayinki nokuqina kokuphrinta.
Ngaphezu kokugcina ukusebenza kahle kokwelapha, ukulawulwa kwesibani se-UV kubalulekile ukuze kuqinisekiswe ukuhambisana nezindinganiso nemithetho yemboni. Izinhlelo zokusebenza eziningi zokuphrinta zidinga imithamo ethile ye-UV ukuze kuzuzwe imiphumela yokwelapha oyifunayo. Ukuqapha okujwayelekile kokuqina kwe-UV kuvumela amaphrinta ukuthi aqinisekise ukuthi isibani sisebenza njengoba kudingekile, ukuqinisekisa ukuthi imikhiqizo ephrintiwe ihlangabezana nezindinganiso zekhwalithi kanye nokulindelwe ukuqina.
Ukuqapha ngempumelelo amandla e-UV ezibani zokuphulukisa ze-UV LED, amaphrinta angasebenzisa ama-radiometer e-UV, okungamathuluzi akhethekile aklanyelwe ukukala ukuphuma kwe-UV. Lawa madivayisi ahlinzeka ngokufundwa okunembile kokuqina kwe-UV, okuvumela amaphrinta ukuthi ahlole ukusebenza kwezibani zawo zokupholisa futhi enze izinqumo ezinolwazi mayelana nokugcinwa nokulungiswa.
Kafushane, umphumela wokuphulukisa woyinki wokuphrinta uncike kakhulu kubukhulu be-UVAmasistimu we-UV LED. Ngokuhlola njalo ukushuba kwe-UV, amaphrinta angakwazi ukugcina ukusebenza kahle kwenqubo yokwelapha, abhekane nokucekelwa phansi okungaba khona noma ukuhluka, futhi aqinisekise ukuthobelana nezindinganiso zomkhakha. Ekugcineni, lo mkhuba unomthelela kwikhwalithi yokuphrinta engaguquki, ukunamathela okuthuthukisiwe kanye nempumelelo iyonke yezinhlelo zokusebenza zokuphrinta ze-inkjet.
