Ibhokisi lebhokisi likagwayi liphrintiwe ngekhasi eligcwele, kanti ukuphrinta akukuhle?
Izimboni zamabhokisi kagwayi zivame ukuthola ama-oda avela kumakhasimende anemikhiqizo ethile noma izidingo ezikhethekile, futhi kudingeka zenze ukuphrinta kwebhokisi likagwayi eligcwele ngemibala ehlukahlukene. Uma kuqhathaniswa nama-oda avamile okuphrinta ibhokisi likagwayi, ukuphrinta kwebhokisi likagwayi eligcwele kudinga ukuphrinta lonke ikhadibhodi lebhokisi likagwayi, elibizayo, elinzima, futhi elichitha imali. Izinga nalo liphakeme.
Ekuphrinteni ibhokisi likagwayi eligcwele ikhasi, umphathi wokuphrinta ibhokisi likagwayi kudingeka ukuthi anake kakhulu ukulawulwa kwemininingwane. Uma ungalaleli, kuzoba nezinkinga ezifana nokuphrinta ibhokisi likagwayi elimhlophe, ukufiphala kombala weyinki, ukulahleka kweyinki yokuphrinta ibhokisi likagwayi, ukuhudula noma ukuphrinta okungekuhle ngokweqile, njll., okubangela ukuthi abaphathi bagcwale amagama. Ukuphrinta ibhokisi likagwayi lepuleti lokuphrinta akukuhle noma akukwazi ukuphrintwa.ibhokisi lekhandlela
Uma kuvela izinkinga ezingenhla, kunconywa ukuthi abaphathi bahlole izindawo ezi-5 ezilandelayo kuqala, okungaxazulula izinkinga eziningi zokuphrinta ibhokisi likagwayi eligcwele ikhasi.
Indawo yokuqala: hlola i-anilox roller kanye ne-raber roller
Uma ulungisa umshini, naka ngokukhethekile ukuthi izinhlangothi ezimbili ze-anilox roller kanye ne-raber roller ziyalingana yini. Siyazi ukuthi umsebenzi we-raber roller ukukhipha uyinki ebusweni be-anilox roller, futhi i-anilox roller ingahlinzeka ngoyinki wepuleti lokuphrinta ibhokisi likagwayi ngendlela yokulinganisa. Lapho iqembu lama-roller lisebenza, lijikeleza nge-centrifugally bese lihlikihlana, futhi lisesimweni sokufana.ibhokisi likashokoledi
Khona-ke ukuthi izikhundla ezinhlangothini zombili zamaqembu amabili ama-roller ziyalingana yini kuhlobene ngqo nokufana kokudluliselwa kweyinki kanye nokubhulasha kweyinki, okuthinta ikhwalithi yezinto eziphrintiwe, futhi kungagwema nenkinga yombala weyinki ongaguquki ngaphambi nangemva kwezinto eziphrintiwe ngezinga elikhulu.
Indawo yesibili: hlola ukujiya kwepuleti/ikhadibhodi
Kuyadingeka ukwazi ukuthi lonke ipuleti lokuphrinta ligcina ukujiya okufanayo ukuqinisekisa ukuthi ingcindezi yokuphrinta ibhokisi likagwayi iyafana kanye noyinki endaweni ebekwe kuyo. Uma ukujiya kwepuleti lokuphrinta ibhokisi likagwayi kungalingani, kuzoba nomehluko ekuphakameni endaweni ebekwe kuyo. Lapho indawo ebekwe kuyo iphakeme, kulula ukunamathisela ipuleti, futhi lapho indawo ebekwe khona iphansi, kulula ukuba noyinki ongaphelele, okuholela ekuprintweni okungacacile kanye nezinye izinkinga.
Ngendlela efanayo, uma ikhadibhodi eligoqiwe linezimbobo ngesikhathi senqubo yokuphatha, khona-ke lapho kunyatheliswa ibhokisi likagwayi, ubuso bephepha lembobo buzoba neziphambeko zekhwalithi kanye nezimpawu ezingacacile, ngakho hlola ngokucophelela ngaphambi kokukhiqiza.
Indawo yesithathu: Hlola i-mesh ye-anilox roller
I-anilox roller ibizwa nangokuthi “inhliziyo yomshini wokunyathelisa ibhokisi likagwayi”. Umsebenzi wayo uthinta ngqo ubuncane kanye nokufana kokunyathelisa ibhokisi likagwayi. Uma ubhala, amandla okumunca uyinki awanele.
Uma isakhiwo se-mesh singama-degrees angu-90, ukudluliselwa kwe-inki kuzokhula kube yimichilo; uma singama-degrees angu-120, isakhiwo sizoba sikwele kakhulu. Njengamanje, umshini wokunyathelisa ibhokisi likagwayi elijwayelekile le-flexographic uvame ukusebenzisa ukuhlelwa kwama-degrees angu-60, kanti i-mesh iyi-ceramic evamile enezinhlangothi eziyisithupha. Uyinki unikezwa nge-anilox roller, ukuze ukudluliselwa kwe-inki kube ngcono, futhi ingcindezi yokunyathelisa ibe ncane futhi izimpawu zokugeleza kwamanzi zibe zincane.
Okwesine: Hlola uyinki osekelwe emanzini
Ekukhiqizweni, uma uhlelo lokuhlinzeka ngoyinki luvinjiwe futhi uyinki ulahlekile; lapho i-roller yerabha kanye ne-anilox roller zithintana ngendlela evamile, uyinki odongeni lwe-anilox roller mesh awukwazi ukucindezelwa, njll., okuhlobene ngokuyisisekelo ne-viscosity ephezulu yeyinki esekelwe emanzini.
Siyazi ukuthi ngesikhathi sokuphrinta ibhokisi likagwayi eligcwele ikhasi, inani likayinki elisetshenziswayo likhulu futhi ukusetshenziswa kuyashesha, futhi uyinki uzokhula ngokushesha. I-viscosity yeyinki esekwe emanzini inobuhlobo obuthile obulinganayo nenani likayinki elidluliselwe. Uyinki ongcono osekwe emanzini uzokwandisa ukumuncwa kweyinki yawo, ngakho-ke Kunconywa ukusebenzisa uyinki osekelwe emanzini osezingeni eliphakathi neliphezulu ukuphrinta ibhokisi likagwayi eligcwele ikhasi, futhi unake ukuhlola izinguquko ze-viscosity zeyinki esekwe emanzini ngesikhathi senqubo yokukhiqiza.ibhokisi lezimbali
