Ukuphrinta kwedijithali

1(34)Ukuphrinta kwedijithali kubhekisela ezindleleni zokunyathelisa kusuka esithombeni esisekelwe kudijithali ngokuqondile kuya enhlobonhlobo yemidiya.[1] Ngokuvamile kubhekiselwa ekuphrinteni okuchwepheshile lapho imisebenzi emincane esuka ekushicileleni kwedeskithophu neminye imithombo yedijithali iphrintwa kusetshenziswa ifomethi enkulu kanye/noma amaphrinta e-laser noma amaphrinta e-inkjet. Ukuphrinta kwedijithali kunezindleko eziphakeme ngekhasi ngalinye kunezindlela zokuphrinta ze-offset ezivamile, kodwa le ntengo ivamise ukuncishiswa ngokugwema izindleko zazo zonke izinyathelo zobuchwepheshe ezidingekayo ukwenza amapuleti okuphrinta. Iphinde ivumele ukuphrinta okudingeka kakhulu, isikhathi esifushane sokushintsha, ngisho nokuguqulwa kwesithombe (idatha eguquguqukayo) esetshenziselwa umbono ngamunye.[2] Ukonga emsebenzini namandla ahlala enyuka emishini yokunyathelisa yedijithali kusho ukuthi ukuphrinta kwedijithali kufinyelela eqophelweni lapho kungase kufane noma kudlule ikhono lobuchwepheshe bokuphrinta be-offset ukukhiqiza amashidi amakhulu ayizinkulungwane ezimbalwa ngentengo ephansi.

Umehluko omkhulu phakathi kokuphrinta kwedijithali nezindlela zendabuko ezifana ne-lithography, i-flexography, i-gravure, noma i-letterpress ukuthi asikho isidingo sokushintsha amapuleti okuphrinta ekuphrinteni kwedijithali, kuyilapho ekuphrinteni kwe-analog amapuleti ashintshwa ngokuphindaphindiwe. Lokhu kubangela isikhathi sokushintsha ngokushesha kanye nezindleko eziphansi uma usebenzisa ukuphrinta kwedijithali, kodwa ngokuvamile ukulahleka kwemininingwane yesithombe esihle ngezinqubo eziningi zokuphrinta zedijithali. Izindlela ezidume kakhulu zifaka i-inkjet noma amaphrinta we-laser afaka umbala noma i-toner ezinhlobonhlobo zama-substrates afaka iphepha, iphepha lesithombe, indwangu, ingilazi, insimbi, imabula, nezinye izinto.

Ezinqubweni eziningi, uyinki noma i-toner ayingeni ku-substrate, njengoba kwenza uyinki ovamile, kodwa yakha ungqimba oluncane olungaphezulu olunganamathela ku-substrate ngokusebenzisa uketshezi lwe-fuser olunenqubo yokushisa (i-toner) noma i-UV. inqubo yokwelapha (uyinki).

Ekuphrinteni kwedijithali, isithombe sithunyelwa ngqo kwiphrinta kusetshenziswa amafayela edijithali afana nama-PDF nalawo avela kusofthiwe yezithombe njenge-Illustrator ne-InDesign. Lokhu kuqeda isidingo sepuleti lokunyathelisa, elisetshenziswa ekunyatheliseni nge-offset, elingonga imali nesikhathi.

Ngaphandle kwesidingo sokudala ipuleti, ukuphrinta kwedijithali kulethe izikhathi zokushintsha ngokushesha nokuphrinta ngokufunwa. Esikhundleni sokuphrinta ama-run amakhulu, anqunywe ngaphambili, izicelo zingenziwa ngokuphrinta okukodwa. Nakuba ukuphrinta kwe-offset kusavame ukuphumela kumaphrinti ekhwalithi engcono kancane, izindlela zedijithali zisetshenzwa ngesivinini esisheshayo ukuze kuthuthukiswe ikhwalithi nezindleko eziphansi.
