Ukungangeni manzi, ifilimu elula okanye izitikha zematte zokuprinta iileyibhile zebhotile ezinemiqulu

Ukusetyenziswa okubanzi kweleyibhile kunye nophuhliso oluqhubekayo lweentlobo zeeleyibhile ngokwemvelo zikhuthaza uphuhliso lweteknoloji yoshicilelo.Ileyibhile yoshicilelo igubungela umcaba, i-convex, i-concave, i-mesh kunye nezinye iindlela zokushicilela, ukusetyenziswa kwamazwe ahlukeneyo akufani.Nangona kunjalo, kunokubonwa kwindlela yophuhliso lweelebhile zehlabathi kwiminyaka yakutshanje ukuba ushicilelo lwe-flexographic, ukuprintwa kwe-rotary emxinwa kunye noshicilelo lwedijithali ziye zaba ngamabala amatsha aqaqambileyo oshicilelo lwelebhile kumazwe aseYurophu naseMelika, kunye nendlela yokuphuhlisa ileyibhile. ushicilelo.

Prepress processing

Kumba wokusetyenzwa koshicilelo lwangaphambili, iiodolo ezininzi eziyilwe ngabathengi ikakhulu ziprinta ngeoffset okanye igravure printing.Ukuba ukuprintwa kwe-flexo kwamkelwa ngolu hlobo lombhalo wesandla, iingxaki ezininzi zekhwalithi ziya kwenzeka kwisampuli, njengokuba umbala ungekho, iileyile azibonakali, kwaye imiphetho enzima ibonakala.Ngoko ke, ukusombulula iingxaki ezinjalo, ukunxibelelana kwangexesha kunye nabathengi kubaluleke kakhulu.

Namhlanje, ukushicilelwa kwelebula kwenziwa ngesandla, kwaye iilebula ezininzi ze-monochrome zenziwa ngomatshini .Onokuphucula ukusebenza kakuhle kwemveliso.Nangona ukuchaneka koshicilelo koomatshini abaninzi abasandul’ ukuveliswa abaprinta iilebhile bengekho phezulu, baye bawuphucula umsebenzi wokushicilela nomgangatho wokushicilela kufuneka uphuculwe.

Inkqubo yokwenza ipleyiti

Ukuprintwa kweleyibhile kugubungela iindlela ezininzi eziphambili zoshicilelo kwinqanaba lokwenziwa kweeplate.Ngokwemvelo yemveliso eyahlukeneyo, khetha iindlela ezahlukeneyo zokushicilela, ngokweendlela ezahlukeneyo zokushicilela, inkqubo yokwenza iplate nayo yahlukile.Eli phepha lithatha inkqubo yokwenza ipleyiti eguquguqukayo njengomzekelo ukwenza intshayelelo emfutshane.

Inkqubo yokuhamba kwe-flexible plate-making yile ilandelayo: i-manuscript yokuqala (ubugcisa), ifilimu (ifilimu engalunganga), ukuvezwa, ukuhlanjululwa, ukomisa kunye nonyango.

1. Umbhalo-ngqangi(ubugcisa).Uyilo lwangaphambili olufanelekileyo ukuprintwa okuguquguqukayo kufuneka lube neempawu ezilandelayo: inani elikhulu lemibala.Kodwa i-overprint encinci;Akukho mfuneko yokuvelisa ngakumbi iinkcukacha ezincinci;Intambo ayiphezulu kakhulu, kodwa inokufezekisa umphumo wokushicilela umbala;Ukupakishwa kokupakisha kunokwenziwa kwi-intanethi.

2. Ifilimu (ifilimu engalunganga).Ukuhlangabezana neemfuno zokwenza iipleyiti, imifanekiso ecacileyo kunye neetekisi, imilinganiselo echanekileyo yobukhulu;Ngefilimu ye-matte, ubuninzi beekona ezine zefilimu kufuneka zihambelane.Ukusetyenziswa kokubhalwa kwefilimu yeziyobisi;Uxinaniso olunokubakho olumhlophe lwalungaphantsi kwe-0.06 xa kuthelekiswa nemitha yoxinano lothumelo.Ubuninzi be-bit emnyama bungaphezulu kwe-3.5.

3. I-exposure ibandakanya ukutyhileka ngasemva kunye nokuvezwa okuphambili.

Ukuvezwa ngasemva.Uguqulelo lwe-photosensitive resin yefilimu exhasayo phezulu, ifilimu ekhuselayo phantsi kwethayile kwidrowa yokuvezwa ukuze ufumane ukuvezwa.Ukukhanya kwe-Uv kugqobhoza ifilimu exhasayo ukuze kuqiniswe umaleko wokuncamathelisa wefotosensitive.Ukuseka isiseko esiluqilima, kunokulawula ubunzulu bokuhlamba, ukomeleza ikhonkco phakathi kwefilimu exhasayo kunye ne-photosensitive resin layer.Ixesha lokuvezwa ngasemva lichongwa ngokuhambelana nobukhulu obufunekayo besiseko.

Ukuvezwa okungundoqo.Ekwabizwa ngokuba kukuvezwa ngaphambili, i-photosensitive resin plate yenkxaso yefilimu iphantsi, ifilimu ekhuselayo phezulu.Ifakwe kwiithayile kwidrowa yokubonisa.Yikrazule ifilimu ekhuselayo ngexesha elinye ngokulandelelana, emva koko uncamathisele indawo yefilimu kwipleyiti ye-photosensitive resin.Indlela yokuvavanya isetyenziswa kwifilimu (ifilimu engeyiyo yeziyobisi icocwa ukwenza ifilimu ibambelele ngokusondeleyo kumaleko we-photosensitive resin. Imitha ye-ultraviolet ingena kwifilimu ye-vacuum kunye nenxalenye yefilimu ecacileyo, ibangela ukuba ipleyiti ye-photosensitive part polymerization iqine. Ubude bexesha eliphambili lokuvezwa limiselwa luhlobo lwepleyiti kunye nobunzulu bomthombo wokukhanya Ixesha lokuvezwa lifutshane kakhulu liya kwenza igrafu kunye nokuthambeka okubhaliweyo kuthe tye kakhulu, imigca egoso, amagama amancinci, amanqaku amancinci ahlanjiwe, ngokuchaseneyo. , ixesha lokuvezwa lide kakhulu liya kusebenzisa uguqulelo, ukubhala kumfiliba Ukuba kukho imigca emikhulu, encinci, engqindilili, ebhityileyo kwipleyiti enye. Gubungela ngefilimu emnyama ngokufanelekileyo kwaye uveze ngokwahlukeneyo. Amalungu amancinci awayi kulahleka ngenxa yokuhlamba , ukuqinisekisa umgangatho wepleyiti.

4. Hlanza.Geza inxalenye ye-photosensitive yesisombululo, gcina i-polymerization yokukhanya yokunceda.Ubude bexesha lokuhlamba ngokobunzima bepleyiti kunye nobunzulu boshicilelo, ixesha lokuhlamba lifutshane kakhulu, ipleyiti ayiyi kushiya i-resin ye-photosensitive kwaye ichaphazele ubunzulu bepleyiti, ixesha lokuhlamba lide kakhulu liya kwenza. ukwandiswa kwepleyiti, okubangela ukuba inxalenye entle deformation okanye ukuwa.

5. Ukomisa.Susa i-solvent yokuhlamba, ukuze ipleyiti ibuyisele ubungakanani bokuqala bobunzima.Ubushushu bokubhaka buphakathi kwe-50-60 ℃.Ixesha lokubhaka ngokobunzima bepleyiti kwaye uhlambe ubude bexesha lokumisela, uguqulelo oluqhelekileyo lweeyure ezimbini, inguqu encinci yeyure.Ixesha lokubhaka lide kakhulu, ukushisa kwepleyiti yokubhaka kuphezulu kakhulu kuya kwenza ipleyiti ibe brittle kwaye ichaphazele ubomi bokushicilela.Iqondo lobushushu lokubhaka liphantsi kakhulu liya kwandisa ixesha lokumisa, ixesha lokubhaka lifutshane kakhulu, ushicilelo luza kuvela inguqu ebolileyo.

6. Emva kokulungiswa.Oko kukuthi, emva kokususwa kokubambelela kunye nokuvezwa.Yenza i-resin photosensitive lukhuni ngokupheleleyo (ipolymerized) ukufezekisa isalathisi sobunzima obufunekayo, kwaye isuse i-viscosity yepleyiti, ukwenzela ukuba kube lula ukuhanjiswa kwe-inki.Ixesha lasemva konyango lifunyenwe ngokuvavanywa ngenjongo yokungaqhekeki okanye ukuncamathela.
