Izindleko Zokunyathelisa Izindleko Ezokudlala Ngendlela Yokunyathelisa
Nakuba izinkampani zokunyathelisa zezokuhweba ezisezingeni eliphezulu zithuthela ekunyathelweni kwedijithali, abaningi bephrinta basasebenzisa indlela yokunyathelisa ye-offset ye-offset kanye neqiniso eye yaba yindinganiso yokunyathelisa kwezohwebo iminyaka engaphezu kwekhulu.
Ukunyatheliswa kokukhipha uhlelo
Ukuhlelwa kwe-lithography-enye yezindlela ezivame kakhulu zokuphrinta inkinobho ekusetshenzisweni kwephepha amapayipi wokunyathelisa ukudlulisela isithombe ephepheni noma kwezinye izigcawu. Amacwecwe ngokuvamile ayenziwe ishidi elincane, kodwa kwezinye izimo, amapuleti angase abe ipulasitiki, i-raber noma iphepha. Amapulangwe ensimbi ayabiza ngaphezu kwephepha noma amanye amapuleti, kodwa ahlala isikhathi eside, akhiqize izithombe eziphezulu ephepheni futhi anembile kakhulu kunezingqwembe ezenziwe ezinye izinto.
Isithombe sibeka emaceleni okunyathelisa usebenzisa inqubo ye-photomechanical noma i-photochemical ngesikhathi sesiteji sokukhiqiza eyaziwa ngokuthi i-prepress-one plate for inkinobho ngayinye yokunyathelisa.
Amapulangwe okuprinta anamathele ema-cylinders epulini yokunyathelisa. Inkinobho namanzi asetshenziselwa ukugudluza bese kudluliselwa ku-cylinder yomphakathi (ingubo) bese ebeka ipuleti, lapho inkinobho ifaka kuphela ezindaweni ezicatshangelwe zeplate. Khona-ke inki idlulisela ephepheni.
Ukucubungula Okuphambene Nokunquma
Umsebenzi wokunyathelisa oqoshwa kuphela ngoyinki omnyama kudinga ipuleti eyodwa kuphela. Umsebenzi wokunyathelisa oqoshwe ngoyinki obomvu newomnyama kudinga amapulethi amabili. Ngokuvamile, amapulethi amaningi adingekayo ukuphrinta umsebenzi, inani eliphakeme.
Izinto ziba nzima nakakhulu uma kubandakanywa izithombe zombala. Ukunyathelisa okungahambisani nokudinga kudinga ukuhlukaniswa kwezithombe ezinemibala zibe yizinki ezine zama-cyan, magenta, ophuzi nabomnyama. Amafayela we-CMYK ekugcineni abe amapuleti amane asebenza kumshini wokunyathelisa ngesikhathi esisodwa kuma-cylinders amane. I-CMYK ihlukile kumbala we-RGB (obomvu, obuluhlaza, obuluhlaza) owubonayo kwikhompyutha yakho. Amafayela adijithali kuwo wonke umsebenzi wokuphrinta ahlolwe futhi ahlelwe ukuze anciphise inani lamapulethi adingekayo ukuphrinta iphrojekthi nokuguqula izithombe zombala noma amafayela azinzima ku-CYMK kuphela.
Kwezinye izimo, kungase kube khona amapuleti angaphezu kwamane-uma i-logo kufanele ibonakale kumbala othile we-Pantone, isibonelo, noma uma inkinobho yensimbi isetshenzisiwe ngaphezu kwemifanekiso enemibala ephelele.
Ngokuya ngobukhulu bomkhiqizo ophethiwe, amakhophi amaningana efayela angashicilelwa ephepheni elikhulu bese ehliswa usayizi emva kwalokho. Uma umsebenzi uveza emaceleni omabili ephepheni, umnyango wokuqedela ungase ubeke lesi sithombe ukunyathelisa zonke izingqimba kwelinye ipulethi kanye nazo zonke izimpande kwenye, ukufakwa okubizwa ngokuthi i-sheetwise, noma kokubili nangaphambili nasemuva kwelinye ipuleti emsebenzini-futhi-ukujika noma isakhiwo somsebenzi nesinye. Kulawa, i-sheetwise ngokuvamile iyabiza kakhulu ngoba kuthatha kabili inani lamacwecwe. Ngokuya ngobukhulu bephrojekthi, inani lamakhompiyutha nobukhulu beshidi, umnyango wokulungisa kuqala ukhetha indlela ephumelelayo kakhulu yokuphoqa iphrojekthi kumapuleti.
Ezinye izinhlobo ze-Plate
Ekunyathelisweni kwesikrini, isikrini silingana nendawo yokunyathelisa. Kungadalwa ngesandla noma nge-photochemically futhi ngokuvamile iyingubo enesibindi noma insimbi yensimbi engenasinhla eselulelwe phezu kwehlaka.
Amapulethi wephepha ngokuvamile afaneleka kuphela ukuphrinta okufishane ngaphandle kwemibala eseduze noma ethintekayo edinga ukumbamba . Hlela umklamo wakho ukuze amapulethi wephepha angasetshenziswa ngempumelelo uma ufuna ukulondoloza imali. Akuwona wonke amaphrinta akhiqiza anikezela le nketho.
