1.Umphumela wephepha embala
Umthelela wephepha embaleni kayinki ungqimba ubonakala kakhulu ezicini ezintathu.
(1) Ubumhlophe bephepha: Iphepha elinobumhlophe obuhlukile (noma elinombala othile) linemiphumela ehlukile ekubukekeni kombala kongqimba lukayinki wokuphrinta.Ngakho-ke, ekukhiqizeni kwangempela, iphepha elinobumhlophe obufanayo kufanele likhethwe ngangokunokwenzeka ukuze kuncishiswe umthelela wobumhlophe bephepha kumbala wokuphrinta.
(2) I-Absorbency: Uma inki efanayo iphrintiwe ephepheni eline-absorbency ehlukene ngaphansi kwezimo ezifanayo, izoba ne-gloss yokuphrinta ehlukile.Uma kuqhathaniswa nephepha elimboziwe, ungqimba lukayinki omnyama lwephepha elingagcotshiwe luzovela lumpunga nomathi, futhi ungqimba lukayinki wombala luzokhukhuleka.Umbala olungiswe uyinki oyi-cyan noyinki we-magenta yiwona osobala kakhulu.
(3) Ukucwebezela nokushelela: Ukucwebezela kwento ephrintiwe kuncike ekucwebezeleni nasekusheleleni kwephepha.Ingaphezulu lephepha lokuphrinta li-semi-glossy, ikakhulukazi iphepha elimboziwe.
2.Umthelela wokwelashwa okungaphezulu kumbala
Izindlela zokwelapha ezingaphezulu zemikhiqizo yokupakisha ikakhulukazi zihlanganisa ukumboza ifilimu (ifilimu ekhanyayo, ifilimu ye-matt), i-glazing (ikhava amafutha agqamile, amafutha e-matt, i-varnish ye-uv), njll. Ngemva kwalezi zindlela zokwelapha ezingaphezulu, indaba ephrintiwe izoba namazinga ahlukene okushintsha umbala kanye ukushintsha kombala.Lapho ifilimu ekhanyayo, amafutha alula namafutha e-Uv eboshwe, ukuminyana kombala kuyanda;Uma ihlanganiswe nefilimu ye-matt namafutha e-matt, ukuminyana kombala kuyehla.Izinguquko zamakhemikhali ikakhulukazi zivela ezinhlobonhlobo zezinyibilikisi eziphilayo eziqukethwe ku-adhesive emboza ifilimu, i-UV primer namafutha e-UV, azoshintsha umbala wongqimba lukayinki wokuphrinta.
3.Umthelela wokuhluka kwesistimu
Inqubo yokwenza amakhadi ombala nge-ink leveler kanye ne-spreader ye-inki iyinqubo yokunyathelisa eyomile, ngaphandle kokubamba iqhaza kwamanzi, kuyilapho ukuphrinta kuyinqubo yokunyathelisa emanzi, ngokubamba iqhaza koketshezi lokumanzisa inqubo yokunyathelisa, ngakho-ke uyinki kufanele idlule uwoyela- emulsification emanzini ekuphrinteni kwe-offset.I-emulsified inki izokhiqiza umehluko wombala nakanjani ngoba ishintsha ukusatshalaliswa kwezinhlayiya ze-pigment kungqimba lukayinki, futhi imikhiqizo ephrintiwe izophinde ibonakale imnyama futhi ingakhanyi.
Ngaphezu kwalokho, ukuzinza kukayinki osetshenziselwa ukuxuba imibala yendawo, ukushuba kongqimba lukayinki, ukunemba kokukala uyinki, umehluko phakathi kwezindawo zokunikezwa kukayinki ezindala nezintsha zomshini wokunyathelisa, isivinini somshini wokunyathelisa, kanye nenani lamanzi elingeziwe ngesikhathi sokuphrinta lizoba nemiphumela ehlukene emehlukweni wombala.
4.Ukulawula ukuphrinta
Ngesikhathi sokuphrinta, iphrinta ilawula ukujiya kongqimba lukayinki wombala wendawo ngekhadi lombala elijwayelekile lokuphrinta, futhi isiza ekulinganiseni inani eliyinhloko lokuminyana kanye nevelu ye-bk yombala nge-densimeter ukuze inqobe umehluko phakathi kokuminyana kombala owomile nomanzi. uyinki.
