Uyinki wokunyathelisa we-liquid gravure uyoma lapho umuntu esebenzisa indlela engokoqobo, okungukuthi, ngokuhwamuka kwezincibilikisi, noyinki wezingxenye ezimbili ngokwelapha ngamakhemikhali.
Iyini i-Gravure Printing
Uyinki wokunyathelisa we-liquid gravure uyoma lapho umuntu esebenzisa indlela engokoqobo, okungukuthi, ngokuhwamuka kwezincibilikisi, noyinki wezingxenye ezimbili ngokwelapha ngamakhemikhali.
Yiziphi izinzuzo kanye nokubi ukuphrinta gravure.
Ikhwalithi yokuphrinta ephezulu
Inani likayinki elisetshenziswa ekuphrinteni i-gravure likhulu, ihluzo nombhalo unomuzwa we-convex, futhi izendlalelo zicebile, imigqa icacile, futhi ikhwalithi iphezulu. Iningi lokuphrinta kwezincwadi, omagazini, izithombe, ukupakishwa kanye nomhlobiso ukuphrinta kwe-gravure
Ukuphrinta kwevolumu ephezulu
Umjikelezo wokwenza amapuleti wokuphrinta i-gravure mude, ukusebenza kahle kuphansi, futhi izindleko ziphezulu. Kodwa-ke, ipuleti lokuphrinta lihlala isikhathi eside, ngakho lifanele ukuphrinta ngobuningi. Uma iqoqo lilikhulu, inzuzo iyanda, futhi ngokuphrinta ngeqoqo elincane, inzuzo iba ngaphansi. Ngakho-ke, indlela ye-gravure ayifanele ukuphrinta amaqoqo amancane ezimpawu zokuthengisa.
(1) Izinzuzo: isisho sikayinki sicishe sibe ngu-90%, futhi umbala ucebile. Ukukhiqiza kabusha kombala okuqinile. Ukumelana nesakhiwo okuqinile. Inani lamaphrinti likhulu. Ukusetshenziswa kwezinhlobonhlobo zamaphepha, ngaphandle kwezinto zephepha nazo zingaphrintwa.
(2) Ububi: izindleko zokwakha amapuleti ziyabiza, izindleko zokunyathelisa nazo ziyabiza, umsebenzi wokwenza amapuleti uba nzima kakhulu, futhi idlanzana lamakhophi anyathelisiwe alifanelekile.
Ama-substrates
I-Gravure ingasetshenziswa ezinhlobonhlobo zezinto zokwakha, kodwa ivame ukusetshenziselwa ukuphrinta iphepha eliphezulu nefilimu yepulasitiki.
Ukubukeka kwamaphrinti: Isakhiwo sihlanzekile, siyafana, futhi azikho izimpawu zokungcola ezisobala. Izithombe nombhalo kubekwe ngendlela efanele. Umbala wepuleti lokuphrinta uyafana ngokuyisisekelo, iphutha losayizi wokuphrinta kahle alikho ngaphezu kuka-0.5mm, ukuphrinta okuvamile akungaphezu kuka-1.0mm, futhi iphutha lokuphrinta ngaphezulu kwezinhlangothi zangaphambili nangemuva alikho ngaphezu kuka-1.0mm.
FAQ
Ukwehluleka ekuphrinteni i-gravure kubangelwa ikakhulukazi amapuleti okuphrinta, oyinki, ama-substrates, ama-squeegists, njll.
(1) Umbala uyinki uyakhanya futhi awulingani
Ukushintsha kombala we-inki ngezikhathi ezithile kwenzeka entweni ephrintiwe. Izindlela zokuqeda zihlanganisa: ukulungisa ukujikeleza kwe-plate roller, ukulungisa i-angle nokucindezela kwe-squeegee noma ukufaka esikhundleni esisha.
(ii) Isigxivizo sinama-mushy futhi sinoboya
Isithombe sendaba ephrintiwe siyahlelwa futhi sinamekwe, futhi unqenqema lwesithombe nombhalo luvela ama-burrs. Izindlela zokuqeda yilezi: ukususa ugesi omile ebusweni be-substrate, ukwengeza ama-solvents e-polar kuyinki, ukwandisa ngokufanele ukucindezela kokunyathelisa, ukulungisa isikhundla se-squeegee, njll.
3)Into eyenza ukuthi u-inki ovimbile ome esikhaleni se-mesh sepuleti lokuphrinta, noma i-mesh cavity yepuleti lokuphrinta igcwaliswe izinwele zephepha kanye nempushana yephepha, ibizwa ngokuthi ukuvimbela ipuleti. Izindlela zokuqeda yilezi: ukukhulisa okuqukethwe kwezincibilikisi kuyinki, ukunciphisa isivinini sokumisa uyinki, nokuphrinta ngephepha elinamandla aphezulu.
4) Ukuchitheka kukayinki nokubona engxenyeni yensimu yendaba ephrintiwe. Izindlela zokuqeda yilezi: ukwengeza uwoyela oyinki oqinile ukuze uthuthukise i-viscosity ye-inki. Lungisa i-engeli ye-squeegee, ukhuphule isivinini sokuphrinta, buyisela ipuleti lokuphrinta le-deep mesh ngepuleti lokuphrinta elinemeshi elingashoni, njll.
5) Amamaki okuklwebha: Imikhondo ye-squeegee endabeni ephrintiwe. Izindlela zokuqeda zihlanganisa ukuphrinta ngoyinki ohlanzekile ngaphandle kokungena kwezinto zangaphandle. Lungisa i-viscosity, ukoma, ukunamathela kweyinki. Sebenzisa i-squeegee yekhwalithi ephezulu ukuze ulungise i-engeli phakathi kwe-squeegee nepuleti.
6) Imvula ye-pigment
Umkhuba wokukhanyisa umbala ekuphrintiwe. Izindlela zokuqeda yilezi: ukuphrinta ngoyinki ngokuhlakazeka okuhle nokusebenza okuzinzile. Izithasiselo ezilwa nokuqubuka kwezulu kanye nezokulwa nemvula zengezwa kuyinki. Roll kahle bese ugoqa uyinki ethangini likayinki njalo.
(7)Ukwenzeka kwamabala ayinki entweni ephrintiwe enamathelayo. Izindlela zokuqeda yilezi: khetha ukuphrinta kukayinki ngesivinini esisheshayo sokushintshashintsha, khulisa izinga lokushisa lokumisa noma unciphise ngokufanelekile isivinini sokuphrinta.
(8) Ukuchithwa kukayinki
Uyinki ophrintwe efilimini yepulasitiki awunamatheli kahle futhi uhlikihlwa ngesandla noma ngamandla omshini. Izindlela zokuqeda yilezi: vimbela ifilimu yepulasitiki kusuka kumswakama, khetha ukuphrinta uyinki ngokuhambisana okuhle nefilimu yepulasitiki, phinda ubeke ifilimu yepulasitiki, futhi uthuthukise ukungezwani kwendawo.
Izitayela zentuthuko
Ngenxa yokuvikelwa kwemvelo kanye nezizathu zempilo, ukudla, imithi, ugwayi, utshwala nezinye izimboni zinaka kakhulu ukuvikelwa kwemvelo kwezinto zokupakisha kanye nezinqubo zokunyathelisa, futhi amabhizinisi okunyathelisa ama-gravure anaka kakhulu imvelo yama-workshops wokunyathelisa. Oyinki namavashishi alungele imvelo azothandwa kakhulu, amasistimu e-squeegee avaliwe kanye nemishini yokushintsha ngokushesha izosakazwa, futhi imishini yokunyathelisa ye-gravure eguqulelwe kuma-inki asekelwe emanzini izosetshenziswa kabanzi.
