Ukunyathelisa nge-offset nokunyathelisa usilika kuyizindlela ezimbili zokunyathelisa ezithandwayo ezisetshenziswa ezindaweni ezihlukahlukene, kuhlanganise namapayipi. Nakuba zisebenzisa inhloso efanayo yokudlulisa imiklamo kumapayipi, kunomehluko omkhulu phakathi kwalezi zinqubo ezimbili.
Ukuphrinta kwe-offset, okubuye kwaziwe ngokuthi i-lithography noma i-offset lithography, kuyindlela yokunyathelisa ehlanganisa ukudlulisa uyinki usuka epuleti lokunyathelisa uye kwengubo yenjoloba, bese igingqa uyinki phezu kwepayipi. Inqubo ihilela izinyathelo eziningi, okuhlanganisa ukulungisa umsebenzi wobuciko, ukwakha ipuleti lokuphrinta, ukufaka uyinki epuletini, nokudlulisa isithombe epayipini.
Enye yezinzuzo eziyinhloko zokuphrinta kwe-offset yikhono layo lokukhiqiza izithombe ezisezingeni eliphezulu, ezinemininingwane, nezibukhali kumapayipi. Lokhu kukwenza kube ukukhetha okudumile kokuphrinta okunembayo okufana namalogo, umbhalo, noma imiklamo eyinkimbinkimbi. Ngaphezu kwalokho, ukuphrinta kwe-offset kuvumela ububanzi bemibala kanye nemiphumela ye-shading, okunikeza amapayipi aphrintiwe ukubukeka okusebenzayo nokubukeka okukhangayo.
Enye inzuzo yokuphrinta kwe-offset ukuthi ingakwazi ukufaka izinto ezihlukahlukene zamapayipi, kuhlanganise nerabha, i-PVC, noma i-silicone. Lokhu kuyenza ibe yindlela yokuphrinta eguquguqukayo elungele izinhlelo zokusebenza zamapayipi ahlukahlukene.
Nokho, ukuphrinta kwe-offset nakho kunemikhawulo yako. Kudinga imishini ekhethekile, kuhlanganise nemishini yokunyathelisa nezingcwecwe zokunyathelisa, okungabiza ukukumisa nokuyinakekela. Ukwengeza, isikhathi sokusetha sokuphrinta kwe-offset side kakhulu uma kuqhathaniswa nezinye izindlela zokuphrinta. Ngakho-ke, kuvame ukonga kakhulu ukuqhutshwa kokukhiqiza okukhulu kunenqwaba encane noma ukuphrinta ngokwezifiso.
ukuphrinta kukasilika, okwaziwa nangokuthi ukuphrinta kwesikrini noma i-serigraphy, kuhlanganisa ukuphusha uyinki esikrinini sendwangu esinezimbobo, phezu kwepayipi. Idizayini yokuphrinta idalwe kusetshenziswa i-stencil, evimba izindawo ezithile zesikrini, evumela ukuthi uyinki udlule ezindaweni ezivulekile ungene epayipini.
Ukuphrinta kukasilika kunikeza izinzuzo ezimbalwa uma kuqhathaniswa nokuphrinta kwe-offset. Okokuqala, kuyisixazululo esingabizi kakhulu semisebenzi yokuphrinta emincane noma eyenziwe ngokwezifiso. Isikhathi sokusetha nezindleko ziphansi uma kuqhathaniswa, okuyenza ilungele ukuphrinta okudingekayo noma ukukhiqiza okufushane.
Okwesibili, ukuphrinta kukasilika kungafinyelela idiphozithi kayinki ejiyile endaweni yepayipi, okuholela ekwakhiweni okugqame kakhulu futhi okunempilo. Lokhu kuyenza ifaneleke izinhlelo zokusebenza ezidinga ukuphrinta okugqamile, okungacacile, okufana namalebula ezimboni noma izimpawu zokuphepha.
Ukwengeza, ukuphrinta kukasilika kuvumela uhla olubanzi lwezinhlobo zikayinki, okuhlanganisa oyinki abakhethekile abafana noyinki ongavimbeli i-UV, wensimbi, noma o-glow-in-the-dark. Lokhu kwandisa amathuba omklamo wokuphrinta kwepayipi, ukuhlangabezana nezidingo ezithile noma ukuthuthukisa umthelela obonakalayo wamapayipi aphrintiwe.
Nokho, ukuphrinta kukasilika kunemikhawulo ethile futhi. Ayifanele ukuzuza imininingwane emihle kakhulu noma imiklamo eyinkimbinkimbi edinga ukunemba okuphezulu. Ukulungiswa kanye nokucija kokuphrinta kukasilika ngokuvamile kuphansi uma kuqhathaniswa nokuphrinta kwe-offset. Ukwengeza, ukunemba kombala nokungaguquguquki kungase kube sengozini ngenxa yemvelo yenqubo eyenziwa ngesandla.
Kafushane, kokubili ukuphrinta kwe-offset nokunyathelisa kukasilika kuyindlela ethandwayo yokunyathelisa yamapayipi. Ukuphrinta kwe-Offset kunikeza imiphumela yekhwalithi ephezulu nenembayo, efanele imiklamo eyinkimbinkimbi kanye nokugijima kokukhiqiza okukhulu. Ukuphrinta kukasilika, ngakolunye uhlangothi, kuyabiza, kuguquguquka, futhi kuvumela ukuphrinta okugqamile, okufiphele noyinki okukhethekile. Ukukhetha phakathi kwalezi zindlela ezimbili kuncike ezidingweni ezithile, isabelomali, nomphumela ofisayo wephrojekthi yokunyathelisa.
