Izikhwama zokupakisha zepulasitiki zivame ukuphrintwa kumafilimu epulasitiki ahlukahlukene, bese zihlanganiswa nezingqimba zokuvimbela kanye nezingqimba zokuvala ukushisa ukuze zakhe amafilimu ayinhlanganisela, ahlukaniswa futhi enziwe izikhwama ukwenza imikhiqizo yokupakisha.Phakathi kwazo, ukuphrinta kuwumugqa wokuqala wokukhiqiza kanye nenqubo ebaluleke kakhulu.Ikhwalithi yokuphrinta ingeyokuqala ukukala izinga lomkhiqizo opakishiwe.Ngakho-ke, ukuqonda nokulawula inqubo yokuphrinta kanye nekhwalithi sekuyisihluthulelo sokukhiqiza ukupakisha okuguquguqukayo.
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 nephilayo, ungqimba lwezithombe ezicebile, umehluko omaphakathi, isithombe esicacile, nomthelela onamandla wezinhlangothi ezintathu.Ukuphrinta kwe-Gravure kudinga ukuthi iphutha lokubhalisa lephethini yombala ngamunye lingabi ngaphezu kuka-0.3mm, futhi ipuleti lokuphrinta lokuphrinta i-gravure linokumelana okuqinile kokuphrinta futhi lifanele imisebenzi yenguqulo ende.Kodwa-ke, 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 ikakhulukazi kusebenzisa iziyinki zokuphrinta ze-flexographic kanye neziyinki zokuphrinta ezisheshe zome.Imishini ilula, izindleko eziphansi, ikhwalithi yepuleti elikhanyayo, ingcindezi ephansi ngesikhathi sokunyathelisa, impahla yepuleti ephansi kanye nokulahlekelwa kwemishini, umsindo ophansi kanye nesivinini esisheshayo ngesikhathi sokunyathelisa.Ipuleti ye-flexographic inesikhathi esifushane sokushintsha ipuleti nokusebenza kahle okuphezulu komsebenzi.Ipuleti le-flexographic lithambile, liyavumelana nezimo, futhi linomsebenzi omuhle wokudlulisa uyinki.Inezinhlobonhlobo zezinto zokunyathelisa.Izindleko zokuphrinta imikhiqizo ye-batch encane ziphansi kunezo zokuphrinta i-gravure.Kodwa-ke, ukuphrinta kwe-flexographic kunezidingo eziphakeme ze-inki ne-plate materials, ngakho ikhwalithi yokuphrinta ingaphansi kancane kwenqubo ye-gravure.
3. Ukuphrinta isikrini
Ngesikhathi sokuphrinta, uyinki udluliselwa ku-substrate ngokusebenzisa i-mesh yengxenye yesithombe ngokuminyanisa kwe-squeegee, okwenza umfanekiso ofanayo nowokuqala.
Imikhiqizo yokuphrinta isikrini inezendlalelo zikayinki ezinothile, imibala egqamile, imibala egcwele, amandla okufihla aqinile, ukukhetha okubanzi kwezinhlobo zikayinki, ukuguquguquka okuqinile, ukucindezela okuphansi ngesikhathi sokuphrinta, ukusebenza okulula, inqubo elula yokwenza amapuleti, ukutshalwa kwezimali kwemishini ephansi, nezindleko eziphansi , Kuhle ukusebenza kahle kwezomnotho, inhlobonhlobo yezinto zokuphrinta.
Ukupakishwa kuphromotha sonke isithombe sempahla esingaphansi kokukhangisa.Inemisebenzi eminingi enjengokwenza impahla ibe yinhle, ukuvikela impahla, nokwenza lula ukujikeleza kwempahla.
