Izikhwama zokupakisha zepulasitiki zivame ukuphrintwa kumafilimu epulasitiki ahlukahlukene, bese zihlanganiswa nezingqimba zokuvimbela kanye nezingqimba zokuvala ukushisa ukuze zakhe amafilimu ayinhlanganisela, asikwa futhi afakwe emasakeni ukuze akhe imikhiqizo yokupakisha.Phakathi kwazo, ukuphrinta kuwumugqa wokuqala wokukhiqiza kanye nenqubo ebaluleke kakhulu.Ukukala izinga lomkhiqizo wokupakisha, ikhwalithi yokuphrinta ingeyokuqala.Ngakho-ke, ukuqonda nokulawula inqubo yokuphrinta kanye nekhwalithi sekuyisihluthulelo sokukhiqiza ukupakisha okuguquguqukayo.
Kunezinqubo ezintathu zokuphrinta ezivame ukusetshenziswa enqubweni yokukhiqiza izikhwama zepulasitiki:
1. Ukuphrinta kwe-Gravure
Ukuphrinta kwefilimu yepulasitiki kusekelwe ikakhulukazi kwinqubo yokuphrinta i-gravure.Ifilimu yepulasitiki ephrintiwe nge-gravure inezinzuzo zekhwalithi ephezulu yokuphrinta, ungqimba lukayinki owugqinsi, umbala ogqamile, iphethini ecacile nekhanyayo, ungqimba lwezithombe olucebile, umehluko omaphakathi, isithombe esicacile nomuzwa oqinile wezinhlangothi ezintathu.Nokho, ukuphrinta kwe-gravure nakho kunokushiyeka okungenakushaywa indiva, njengenqubo eyinkimbinkimbi yokwenza amapuleti angaphambi komshini, izindleko eziphezulu, umjikelezo omude, nokungcola okukhulu.
2. Ukuphrinta kwe-Flexographic
Ukuphrinta kwe-Flexographic ngokuyinhloko kusebenzisa oyinki be-letterpress be-flexographic futhi aboma ngokushesha.Imishini ilula, izindleko ziphansi, impahla yepuleti ilula ngesisindo, ingcindezi yokunyathelisa incane, impahla yepuleti nokulahlekelwa kwemishini kuncane, umsindo wokunyathelisa mncane, futhi ijubane liyashesha.Ipuleti ye-flexo inesikhathi esifushane sokushintsha ipuleti kanye nokusebenza kahle okuphezulu komsebenzi.Ipuleti le-flexo lithambile, liyanwebeka, futhi linomsebenzi omuhle wokudlulisa uyinki.Inezinhlobonhlobo zezinto zokuphrinta, futhi izindleko zokuphrinta amaqoqo amancane emikhiqizo ziphansi kunezo zokuphrinta i-gravure.Kodwa-ke, ukuphrinta kwe-flexographic kunezidingo eziphakeme ku-inki ne-plate materials, ngakho ikhwalithi yokuphrinta ingaphansi kancane kunenqubo ye-gravure.
3. Ukuphrinta isikrini
Ngesikhathi sokuphrinta, ngokusebenzisa i-extrusion ye-scraper, uyinki udluliselwa ku-substrate nge-mesh yengxenye yesithombe ukuze kwakhe isithombe esifanayo nesoqobo.Imikhiqizo yokuphrinta isikrini inezingqimba zikayinki ezinothile, imibala egqamile, imibala egcwele, amandla okuvala aqinile, ukukhetha okubanzi kwezinhlobo zikayinki, ukuguquguquka okuqinile, ukucindezela okuphansi ngesikhathi sokuphrinta, ukusebenza okulula, inqubo elula yokwenza amapuleti, kanye nokutshalwa kwezimali kwemishini ephansi, ngakho-ke izindleko ziphansi. , Izinzuzo ezinhle zezomnotho, izinhlobonhlobo zezinto zokunyathelisa.
