Ukumataniswa Koyinki Wokuphrinta Okungaxhunyiwe ku-UV Kunqubo Yokuphrinta
Oyinki bokuphrinta be-UV offset, njengendlela yokuthwebula ekuphrinteni, badlala indima ebalulekile ekunqumeni ithoni, ukugcwala kombala, nokucaca kwezithombe eziphrintiwe. Ngokuthuthuka kwezobuchwepheshe bokuphrinta, izinto ezisetshenziswayo, kanye namazinga ahlobene, oyinki kufanele bavumelane nama-substrates ahlukahlukene kanye nezinqubo zokuphrinta, okuholela ekukhuphukeni kwezidingo zobuchwepheshe zoyinki. Lokhu kudale ukwakheka kukayinki okuningi, ngakunye kunezici ezihlukile nezinhlelo zokusebenza ezithile, okugcizelela izixazululo eziklanyelwe kanye nekhono. Lapho kukhethwa oyinki, amabhizinisi okuphrinta akumele nje ahlangabezane nenqubo yawo yokunyathelisa kanye nezidingo zekhwalithi kodwa futhi ahambisane nezindinganiso kazwelonke zokukhishwa kwe-VOC kanye nemithethonqubo yokuvikela imvelo, ngaleyo ndlela onge izindleko futhi agweme izinkinga zokulawula.
Ezimbonini ezehlukene ezinjengogwayi, utshwala, izimonyo, izinto zikagesi, ukudla, kanye nokupakishwa kwemithi, ukusetshenziswa koyinki be-UV offset kusabalele, okwenza kudingeke ukuthi kulandelwe izimiso zemvelo ezithize embonini. Isibonelo, embonini ye-elekthronikhi, ukuhambisana ne-IEC 61249-2-21:2003 indinganiso ye-halogen-free kuyisibopho ukuvimbela ukuwohloka kokusebenza kukagesi okubangelwa yi-halogen kanye nokwakhiwa kwama-dioxin ayingozi emvelweni.
Ama-substrates ahlukene okuphrinta, okuhlanganisa amaphepha, amafilimu, izindwangu, izinsimbi, nezitsha zobumba, abonisa ukungezwani okuguquguqukayo kwendawo ngenxa yokwakheka kwawo okubalulekile nokwelashwa kwendawo, okuthinta ukunamathela kukayinki. Ngaphandle kokunamathela, ukuhambisana kwamakhemikhali phakathi kukayinki ne-substrate kufanele kubhekwe ukuze kugwenywe izinto ezinjengokuluma kancane noma ukuguquguquka kombala kumakhemikhali achetshiwe kanye nokunamathela kabusha kukayinki.
Izinqubo zangemuva kokuphrinta ezifana nokusika i-die-cutting kanye nokugxiviza okushisayo zibeka izidingo ezithile ezicini ze-inki, okwenza kudingeke ukuthi kusetshenziswe oyinki abaguquguqukayo abanokuqina okufanele kwendawo ukuze kuvinjelwe ukuhlakazeka kombala ngesikhathi sokucubungula noma ukwehluleka kulezi zindlela zokuqedela.
Ngaphezu kwalokho, ngokuya ngezicelo zomkhiqizo—njengamakhadi noma ukupakishwa kwezimonyo—uyinki kufanele agcwalise imibandela ethile yokusebenza, njengokumelana nokuhuzuka okuphezulu, imibala egqamile emelana nokufiphala, nokukhanya okuhle kakhulu, okuqinisekisa ukuthi imikhiqizo igcina ukubukeka okukhangayo ngokuhamba kwesikhathi futhi ikhanga abathengi.
