Izitika ezingangeni manzi, ifilimu ekhanyayo noma izitikha zebhodlela le-matte ezinamaroli

Ukusetshenziswa okubanzi kwelebula nokuthuthukiswa okuqhubekayo kwezinhlobo zamalebula ngokwemvelo kukhuthaza ukuthuthukiswa kobuchwepheshe bokuphrinta ilebula.Ukuphrinta ilebula kuhlanganisa isicaba, i-convex, i-concave, i-mesh nezinye izindlela zokunyathelisa, ukusetshenziswa kwamazwe ahlukene akufani.Kodwa-ke, kungabonakala ekuthuthukisweni kwamalebula omhlaba eminyakeni yamuva nje ukuthi ukuphrinta kwe-flexographic, ukuphrinta kwe-rotary emincane emincane kanye nokuphrinta kwedijithali sekuphenduke izindawo ezintsha ezikhanyayo zokuphrinta ilebula emazweni aseYurophu naseMelika, kanye nomkhuba wokuthuthukiswa kwelebula. ukunyathelisa.

Cindezela ukucubungula

Esicini sokucutshungulwa kwangaphambi kokucindezela, ama-oda amaningi aklanywe ngamakhasimende ngokuyinhloko awokuphrinta kwe-offset noma ukuphrinta kwe-gravure.Uma ukuphrinta kwe-flexo kwamukelwa kulolu hlobo lombhalo wesandla, izinkinga eziningi zekhwalithi zizokwenzeka kusampula, njengokuthi umbala ungekho endaweni, izendlalelo azibonakali, futhi imiphetho eqinile ibonakala.Ngakho-ke, ukuxazulula izinkinga ezinjalo, ukuxhumana okufika ngesikhathi namakhasimende kuyadingeka kakhulu.

Namuhla, ukuphrinta ilebula kwenziwa ngesandla, futhi amalebula amaningi e-monochrome enziwa ngomshini .Okungathuthukisa ukusebenza kahle kokukhiqiza.Nakuba ukunemba kokunyathelisa kwemishini eminingi esanda kuthuthukiswa yokunyathelisa amalebula kungephezulu, iye yathuthukisa ukusebenza kahle kokunyathelisa kanye nezinga lokunyathelisa lidinga ukuthuthukiswa.

Inqubo yokwenza amapuleti

Ukuphrinta ilebula kuhlanganisa izindlela ezimbalwa zokuphrinta eziyinhloko esigabeni sokwenza amapulangwe.Ngokusho kwemvelo yomkhiqizo ohlukile, khetha izindlela zokuphrinta ezihlukene, ngokwezindlela ezihlukene zokuphrinta, inqubo yokwenza ipuleti nayo ihlukile.Leli phepha lithatha inqubo yokwenza amapuleti aguquguqukayo njengesibonelo ukwenza isingeniso esifushane.

Ukugeleza kwenqubo yokwenza amapuleti aguquguqukayo kungokulandelayo: umbhalo wesandla wokuqala (ubuciko), ifilimu (ifilimu engalungile), ukuchayeka, ukugeza, ukomisa kanye nokwelashwa.

1. Umbhalo wesandla(ubuciko).Umklamo wangempela ofanele ukuphrinta okuguquguqukayo kufanele ube nezici ezilandelayo: inombolo enkulu yemibala.Kodwa i-overprint encane;Asikho isidingo sokukhiqiza kabusha imininingwane emincane kakhulu;Ikhebula aliphezulu kakhulu, kodwa lingafinyelela umphumela wokuphrinta umbala;Ukucubungula ukupakisha kungenziwa ku-inthanethi.

2. Ifilimu (ifilimu engalungile).Hlangana nezidingo zokwenza amapuleti, izithombe ezicacile nemibhalo, ukucaciswa kosayizi okunembile;Ngefilimu ye-matte, ukuminyana kwamakhona amane efilimu kufanele kuhambisane.Ukusetshenziswa kwe-orthography yefilimu yezidakamizwa;Amandla amhlophe anamandla angaphansi kuka-0.06 akalwa imitha yokudlulisela ukuminyana.I-black bit density ingaphezu kuka-3.5.

3. Ukuchayeka kubandakanya ukuchayeka emuva kanye nokuchayeka okukhulu.

Ukuchayeka emuva.Inguqulo ye-photosensitive resin yefilimu esekelayo phezulu, ifilimu evikelayo eya phansi ithayela ekhabetheni lokuchayeka ukuze uthole ukuchayeka.Ukukhanya kwe-Uv kungena kwifilimu esekelayo ukuze kuqiniswe isendlalelo sokunamathisela esizwela isithombe.Ukusungula isisekelo esiqinile, kungaphinda kulawule ukujula kokugeza, kuqinise isibopho phakathi kwefilimu esekelayo nesendlalelo se-photosensitive resin.Isikhathi sokuchayeka emuva sinqunywa ngokusho kokuqina kwesisekelo esidingekayo.

Ukuchayeka okuyinhloko.Okwaziwa nangokuthi ukuchayeka ngaphambili, ifilimu ye-photosensitive resin plate isekela phansi, ifilimu evikelayo phezulu.Kufakwe amathayela ekhabetheni lokuchayeka.Khipha ifilimu yokuvikela kanye zilandelana, bese unamathisela indawo yefilimu epuleti le-photosensitive resin.Indlela yokuhlola isetshenziswa efilimini (ifilimu engeyona eyezidakamizwa igezwa ukuze kwenziwe ifilimu inamathele eduze kwesendlalelo se-photosensitive resin. Umsebe we-ultraviolet ungena efilimini ye-vacuum kanye nengxenye yefilimu ebonisa ngale, ibangela ukuthi ingxenye ye-photosensitive polymerization iqine. Ubude besikhathi sokuchayeka okuyinhloko bunqunywa uhlobo lwepuleti kanye namandla omthombo wokukhanya. Isikhathi sokuchayeka sifushane kakhulu sizokwenza igrafu nombhalo othambekayo uqonde kakhulu, imigqa egobile, amagama amancane, amaphuzu amancane ahlanzwe ngaphandle, ngokuphambene nalokho. , isikhathi sokuchayeka side kakhulu sizosebenza inguqulo, umbhalo wesandla ufiphalisiwe. Uma kukhona imigqa emikhulu, emincane, ewugqinsi, emincane epuletini elifanayo. Mboza ngefilimu emnyama ngokufanelekile futhi uveze ngokuhlukile. Izingxenye ezincane ngeke zilahleke ngenxa yokuwashwa , ukuqinisekisa ikhwalithi yepuleti.

4. Hlanza.Geza ingxenye yesixazululo e-photosensitive, gcina i-polymerization ekhanyayo yokusiza.Ubude besikhathi sokugeza ngokuya ngokuqina kwepuleti nokujula kokuphrinta, isikhathi sokugeza sifushane kakhulu, ipuleti ngeke lishiye i-photosensitive resin futhi lithinte ukujula kwepuleti, isikhathi sokugeza side kakhulu sizokwenza ukunwetshwa kwepuleti, okuholela ekuguqulweni kwengxenye enhle noma ukuwa.

5. Ukomisa.Susa ukugeza i-solvent, ukuze ipuleti libuyisele usayizi wangempela wokushuba.Izinga lokushisa lokubhaka liphakathi kuka-50-60 ℃.Isikhathi sokubhaka ngokusho kobukhulu bepuleti futhi ugeze ubude besikhathi sokunquma, inguqulo evamile ewugqinsi yamahora amabili, inguqulo encane yehora.Isikhathi sokubhaka side kakhulu, izinga lokushisa lepuleti lokubhaka liphezulu kakhulu lizokwenza ipuleti libe brittle futhi lithinte impilo yokuphrinta.Izinga lokushisa lokubhaka liphansi kakhulu lizokwandisa isikhathi sokumisa, isikhathi sokubhaka sifushane kakhulu, ukuphrinta kuzovela inguqulo ebolile.

6. Ngemuva kokucubungula.Okusho ukuthi, ngemuva kokususwa kokunamathela nokuchayeka.Yenza resin photosensitive lukhuni ngokuphelele (polymerized) ukuze kuzuzwe ubulukhuni efanele Inkomba, futhi asuse viscosity plate, ukuze kube lula ukudluliswa uyinki.Isikhathi sangemuva kokwelashwa sitholwe ngokuhlolwa ngenhloso yokungaqhekezi noma ukunamathela.
