Ipuleti lokuphrinta liyingxenye ebalulekile yenqubo yokudlulisa isithombe ku-substrate efana nephepha noma indwangu. Zisetshenziswa ngezindlela ezahlukahlukene zokuphrinta, kufaka phakathi ukuphrinta kwe-offset, i-flexographic kanye ne-gravure. Uhlobo ngalunye lweipuleti lokunyathelisainezici ezihlukile futhi ifanele izinhlelo zokusebenza ezithile zokuphrinta. Kulesi sihloko, sizohlola izinhlobo ezintathu eziyinhloko zezinhlelo zokuphrinta kanye nokusetshenziswa kwazo ngokulandelana kwazo.
Amapuleti okuphrinta e-offset asetshenziswa kakhulu ekunyatheliseni kwezentengiselwano ngenxa yokuphuma kwawo kwekhwalithi ephezulu kanye nokuhlukahluka. Lawa mapuleti ngokuvamile enziwe nge-aluminium noma i-polyester futhi ahlanganiswe ne-emulsion ye-photosensitive. Isithombe esizophrintwa sidluliselwa epuleti lokuphrinta kusetshenziswa inqubo yezithombe lapho izindawo ezingezona izithombe zibhekwa njengezimunca amanzi futhi izindawo zesithombe ziphathwa ngendlela yokumunca uyinki.
Kunezinhlobo ezimbili eziyinhloko zamapuleti okuphrinta e-offset: amapuleti okuphrinta e-analog endabuko kanye namapuleti okuphrinta edijithali esimanje. Amapuleti endabuko okuphrinta analogi adinga isithombe esihlukile esinegethivu, esisetshenziselwa ukuveza ipuleti. Amapuleti edijithali, ngakolunye uhlangothi, angenziwa isithombe ngokuqondile kusetshenziswa ubuchwepheshe be-computer-to-plate (CTP), aqede isidingo sefilimu, okwenza inqubo isebenze kahle.

Ipuleti eliqinile elimaphakathi, elithuthukiselwe ukuphrinta imiklamo ehlanganisa ama-halftones nezinto eziqinile epuletini elilodwa. Ilungele wonke ama-substrates asetshenziswa ngokuvamile amuncayo nangamubi (okungukuthi ipulasitiki ne-aluminium foil, amabhodi amboziwe futhi angagcotshiwe, liner ephrintiwe ngaphambili). ubuncane bechashazi lokuzuza ku-halftone.I-wide exposure latitude kanye nokujula okuhle kokukhululeka.Kufanele ukusetshenziswa ngamanzi noyinki wokunyathelisa osekelwe etshwaleni.
Amapuleti okuphrinta e-offset aziwa ngekhono lawo lokukhiqiza izithombe ezibonisa ukulungiswa okuphezulu kanye nemininingwane ecacile, okuwenza afanelekele izinto zokunyathelisa ezifana nomagazini, izincwajana kanye nokupakisha. Baphinde banikeze inzuzo yokushintsha kwepuleti okusheshayo nokulula, okuholela ezikhathini ezisheshayo zokushintsha umsebenzi.
Ipuleti lokuphrinta le-Flexographic, ukuphrinta kwe-Flexographic, noma ukuphrinta kwe-flexographic, kuyisinqumo esidumile sokuphrinta kuma-substrates aguquguqukayo njengepulasitiki, iphepha, nekhadibhodi. Amapuleti okuphrinta e-Flexographic ngokuvamile enziwe ngezinto zerabha noma ze-photopolymer futhi afakwe kuma-roller ngenqubo yokuphrinta. Lawa mapuleti aklanyelwe ukudlulisa uyinki endaweni engaphansi kusetshenziswa impumuzo eguquguqukayo evumelana namakhonsathi wendawo yokuphrinta.
Amapuleti e-Photopolymer yiwona asetshenziswa kakhulu amapuleti wokuphrinta we-flexographic. Zenziwe ngokudalula okokusebenza kwe-photopolymer ngokusebenzisa ukukhanya okunegethivu kuya ku-UV, okwenza izindawo zesithombe zibe lukhuni kuyilapho kushiya izindawo ezingezona izithombe zithambile futhi zigezeka. Inqubo inika amandla ukukhiqizwa kwesithombe okunembayo nokungaguquguquki, okwenza amapuleti e-photopolymer alungele amalebula okuphrinta, ukupakisha neziqukathi zikathayela.
Amapuleti okuphrinta e-Flexographic aziwa ngekhono lawo lokuphatha izinhlobonhlobo zamayinki nama-substrates, okuwenza afanelekele ukusetshenziswa okuhlukahlukene embonini yokupakisha nokulebula. Baphinde banikeze amandla okuphrinta ngesivinini esikhulu, okwenza kube ukukhetha okungabizi kakhulu kokuphrinta kwevolumu ephezulu.
Ipuleti yokuphrinta ye-Gravure, ukuphrinta kwe-Gravure, eyaziwa nangokuthi ukuphrinta kwe-gravure, iyikhwalithi ephezulu, inqubo yokuphrinta yevolumu ephezulu evame ukusetshenziselwa ukudala omagazini, ikhathalogi, namaphrinti okuhlobisa. Amapuleti okuphrinta ama-Gravure enziwe ngethusi noma ngensimbi e-chromed futhi anamaseli ahlehlisiwe noma izimbobo ezibamba uyinki. Isithombe siqoshwa noma siqoshwe epuletini kusetshenziswa inqubo yamakhemikhali noma yomshini, kwakheka iphethini yamaseli ehambisana nesithombe osifunayo.
Izinhlobo ezimbili eziyinhloko zamapuleti okuphrinta ama-gravure yi-cylinder ne-flatbed. Amapuleti angama-cylinder asongwe ngesilinda futhi asetshenziselwa ukuphrinta okuqhubekayo, kuyilapho amapuleti ayisicaba asetshenziselwa ukuphrinta okufushane kanye nezinhlelo zokusebenza ezikhethekile. Amapuleti okuphrinta ama-Gravure ayakwazi ukukhiqiza imininingwane emihle kanye nezinhlobonhlobo zamathoni, okuwenza afanelekele ukukhiqizwa kwesithombe sekhwalithi ephezulu.
Amapuleti okuphrinta ama-Gravure aziwa ngokuqina kwawo kanye nokuphrinta okude, okuwenza abe yinketho yokuqala yemisebenzi yokuphrinta yevolumu ephezulu. Bayakwazi futhi ukuphrinta kuma-substrates ahlukahlukene, kuhlanganise nephepha, ipulasitiki nensimbi, okubenza bafanelekele izinhlelo zokusebenza zokuphrinta ezahlukene.
Kafushane, amapuleti okunyathelisa anendima ebalulekile embonini yokunyathelisa, futhi ukuqonda izinhlobo ezihlukahlukene zezingcwecwe zokunyathelisa kubalulekile ekukhetheni indlela efanele yomsebenzi othile wokunyathelisa. Ukuthi amapuleti okuphrinta e-offset okuphrinta kwezentengiso anesinqumo esiphezulu, amapuleti okuphrinta e-flexographic okupakishwa okuguquguqukayo, noma i-gravureamapuleti okunyathelisangokushicilelwa kwevolumu ephezulu, uhlobo ngalunye lwepuleti lokuphrinta lunikeza izinzuzo eziyingqayizivele kanye noMsebenzi. Ngokukhetha ipuleti lokuphrinta elilungile, amaphrinta angafinyelela ikhwalithi yokuphrinta nokusebenza kahle akudingayo ngezidingo zabo zokuphrinta ezithile.
