Ukuphrinta kwe-offset kanye nokuphrinta isilika kuyizindlela ezimbili ezidumile zokuphrinta ezisetshenziswa ezindaweni ezahlukene, kufaka phakathi amapayipi. Nakuba kufeza injongo efanayo yokudlulisela imiklamo kumapayipi, kunomehluko omkhulu phakathi kwalezi zinqubo ezimbili.
Ukuphrinta kwe-offset, okwaziwa nangokuthi i-lithography noma i-offset lithography, kuyindlela yokuphrinta ehilela ukudlulisa uyinki usuka epuletini lokuphrinta uye engutsheni yerabha, bese ugoqa uyinki phezu kwepayipi. Le nqubo ihilela izinyathelo eziningi, okuhlanganisa ukulungiselela umsebenzi wobuciko, ukudala ipuleti lokuphrinta, ukufaka uyinki epuletini, nokudlulisela isithombe epayipini.
Enye yezinzuzo eziyinhloko zokunyathelisa nge-offset yikhono layo lokukhiqiza izithombe ezisezingeni eliphezulu, ezinemininingwane, nezibukhali kumapayipi. Lokhu kwenza kube ukukhetha okuthandwayo kokunyathelisa ngokunemba njengama-logo, umbhalo, noma imiklamo eyinkimbinkimbi. Ngaphezu kwalokho, ukunyathelisa nge-offset kuvumela imibala ehlukahlukene nemiphumela yokufiphaza, okunikeza amapayipi anyathelisiwe ukubukeka kobungcweti nokukhangayo.
Enye inzuzo yokunyathelisa nge-offset ukuthi ingathwala izinto ezahlukahlukene zamapayipi, kufaka phakathi irabha, i-PVC, noma i-silicone. Lokhu kwenza kube yindlela yokunyathelisa eguquguqukayo efanelekela ukusetshenziswa kwamapayipi ahlukene.
Kodwa-ke, ukuphrinta kwe-offset nakho kunemikhawulo yako. Kudinga imishini ekhethekile, kufaka phakathi imishini yokunyathelisa namapuleti okunyathelisa, okungabiza kakhulu ukuwasetha nokunakekela. Ngaphezu kwalokho, isikhathi sokusetha sokunyathelisa kwe-offset side kakhulu uma kuqhathaniswa nezinye izindlela zokunyathelisa. Ngakho-ke, kuvame ukuba ngcono kakhulu ekukhiqizeni okukhulu kunokunyathelisa okuncane noma okwenziwe ngokwezifiso.
Ukuphrinta isilika, okwaziwa nangokuthi ukuphrinta kwesikrini noma i-serigraphy, kuhilela ukusunduza uyinki esikrinini sendwangu esinezimbobo, phezu kwepayipi. Umklamo wokuphrinta wenziwa kusetshenziswa i-stencil, evimba izindawo ezithile zesikrini, okuvumela uyinki ukuthi udlule ezindaweni ezivulekile uye epayipini.
Ukuphrinta usilika kunikeza izinzuzo eziningana uma kuqhathaniswa nokuphrinta kwe-offset. Okokuqala, kuyisisombululo esingabizi kakhulu semisebenzi yokuphrinta yobuningi obuncane noma eyenziwe ngokwezifiso. Isikhathi sokusetha kanye nezindleko ziphansi kakhulu, okwenza kube kuhle kakhulu ekuphrinteni okufunwayo noma ekukhiqizeni okufushane.
Okwesibili, ukuphrinta usilika kungafeza idiphozithi yeyinki ejiyile ebusweni bepayipi, okuholela ekuklanyweni okuvelele nokugqamile. Lokhu kuyenza ifaneleke ezinhlelweni zokusebenza ezidinga ukuphrinta okugqamile nokungacaci, njengamalebula ezimboni noma izimpawu zokuphepha.
Ngaphezu kwalokho, ukuphrinta usilika kuvumela izinhlobo eziningi zeyinki, okuhlanganisa noyinki abakhethekile njengoyinki omelana ne-UV, insimbi, noma okhanyayo ebumnyameni. Lokhu kwandisa amathuba okuklama okuphrinta ipayipi, ukuhlangabezana nezidingo ezithile noma ukuthuthukisa umthelela obonakalayo wamapayipi aphrintiwe.
Kodwa-ke, ukuphrinta usilika kunemikhawulo ethile. Akufanelekile ukufeza imininingwane emincane kakhulu noma imiklamo eyinkimbinkimbi edinga ukunemba okuphezulu. Ukulungiswa kanye nokubukhali kokuphrinta usilika ngokuvamile kuphansi uma kuqhathaniswa nokuphrinta kwe-offset. Ngaphezu kwalokho, ukunemba kombala kanye nokuvumelana kungase kube sengozini encane ngenxa yemvelo yenqubo esetshenziswa ngesandla.
Ngamafuphi, kokubili ukuphrinta kwe-offset kanye nokuphrinta kwesilika kuyizindlela zokuphrinta ezidumile zamapayipi. Ukuphrinta kwe-offset kunikeza imiphumela esezingeni eliphezulu neqondile, efanelekela imiklamo eyinkimbinkimbi kanye nokukhiqiza okukhulu. Ukuphrinta kwesilika, ngakolunye uhlangothi, kuyabiza, kuyasebenziseka, futhi kuvumela ukuphrinta okugqamile, okungacacile kanye noyinki okhethekile. Ukukhetha phakathi kwalezi zindlela ezimbili kuncike ezidingweni ezithile, isabelomali, kanye nomphumela ofiselekayo wephrojekthi yokuphrinta.
