Ukuqinisekisa ngedijithali kuwuhlobo lobuchwepheshe bokuqinisekisa obucubungula imibhalo yesandla ye-elekthronikhi ngedijithali futhi ikhiphe ngokuqondile ekushicilelweni kwe-elekthronikhi. Isetshenziswa kabanzi ngenxa yezinzuzo zayo njengejubane, ukunethezeka, futhi asikho isidingo sokwenza amapuleti. Phakathi nenqubo yamasampula, amakhasimende avame ukubika izinkinga njengokuthi "ukunemba kwesampula ephansi" kanye "nekhwalithi embi". Ukuqonda izinto ezilandelayo ezithinta amasampula edijithali kungasiza amabhizinisi ukuhlonza izinkinga ngokushesha futhi athuthukise ikhwalithi yokuphrinta.
1.Ukunemba kokuphrinta
Isimo sokusebenza sekhanda lokuphrinta lephrinta ye-inkjet sizothinta ngokuqondile umphumela wokukhiphayo wokuqinisekisa kwedijithali. Ukunemba kokuphrinta okungafinyelelwa yikhanda lokuphrinta kunquma ukunemba kokukhiphayo kokuqinisekisa kwedijithali, futhi amaphrinta anokulungiswa okuphansi awakwazi ukuhlangabezana nezidingo zokuqinisekisa kwedijithali. Ukunemba okuvundlile kwephrinta kunqunywa ukusatshalaliswa kwekhanda lokuphrinta, kuyilapho ukunemba okuqondile kuthintwa yi-stepper motor. Uma iphepha lingaphakelwa kahle, kungase kuvele imigqa evundlile, engathinta nokunemba kokuphrinta. Ukuze kuqinisekiswe ukucaca nokunemba kwesithombe esiphrintiwe, kuyadingeka ukwenza izinguquko nezilawuli ezinhle emshinini wokunyathelisa ngaphambi kobufakazi bedijithali.
Ukwengeza, ukulungiswa kombhalo wesandla ophrintiwe nakho kudinga ukulawulwa ngaphakathi kwebanga elithile ukuze kuqinisekiswe ukucaca kanye nemininingwane yendaba ephrintiwe. Mayelana nokucubungula izithombe, isofthiwe yekhwalithi ephezulu yokucubungula izithombe ingasetshenziswa ukucubungula okwangempela okuphrintiwe ukuze kuthuthukiswe ukucaca kwesithombe nokunemba. Phakathi naleso sikhathi, ngesikhathi senqubo yokunyathelisa, kuyadingeka ukulawula isikhundla kanye nesivinini sokunyakaza kombhalo wesandla ophrintiwe ukuze kuqinisekiswe ukucaca nokunemba kwesithombe. Ngakho-ke, ukulungiswa okunembile nokulawula umshini wokunyathelisa, isofthiwe yekhwalithi ephezulu yokucubungula izithombe, ukulungiswa okufanelekile kokuphrinta kwangempela, kanye nesivinini esifanelekile sokunyathelisa nesimo kuyizici ezibalulekile zokuqinisekisa ukucaca nokunemba kwezithombe eziphrintiwe.
2.Uyinki wokuphrinta
Ukunemba kombala kuyisici esibalulekile esithinta ikhwalithi yemikhiqizo ephrintiwe ezinqubweni zokuphrinta zedijithali. Enqubweni yokunyathelisa, ukuze kuzuzwe ukunemba okuphelele kombala, umshini wokunyathelisa kufanele unikeze ngokunembile imibala namathoni adingekayo, futhi ulawule ngokunembile ibhalansi yombala kanye nebhalansi ye-grayscale yomkhiqizo ophrintiwe.
Isikhala sombala esisetshenziswa kakhulu yisikhala sombala se-CMYK, esifinyelela umphumela wombala ofisayo ngokulungisa ukulingana kwemibala e-Cyan, Magenta, Ephuzi, kanye Nemnyama. Ukuqinisekisa ukunemba kombala, imishini yokunyathelisa ivamise ukuhlonywa amathuluzi akhethekile okuthola umbala ukuze kutholwe futhi kulungiswe umbala nethoni yeyinki. Ngaphezu kwalokho, kuyadingeka ukulungisa ibhalansi yombala kanye nebhalansi ye-grayscale yendaba ephrintiwe ukuze kuqinisekiswe ukunemba nokuvumelana kombala wendaba ephrintiwe. Ngakho-ke, ohlelweni lokuphrinta kwedijithali, ukulawula okunembile kanye nokulungiswa kombala we-inki nethoni, kanye nebhalansi yombala ne-grayscale yemikhiqizo ephrintiwe, izinyathelo ezibalulekile zokuqinisekisa ukunemba kombala wemikhiqizo ephrintiwe.
3.Iphepha lokuphrinta
Iphepha lokufakazela idijithali linezidingo eziphezulu zekhwalithi yokuphrinta isithombe, ukucwebezela kwephepha, nokuvumelana nezimo zephepha, kuyilapho izithombe eziphrintiwe ngephepha kufanele zithinteke kancane ekushintsheni kwemvelo. Iphepha lokufakazela idijithali lidinga ukumuncwa kahle kukayinki, ukumuncwa ngokushesha kwamaconsi ayinki, futhi akukho ukunqwabelana kukayinki noma ukunqwabelana kombala lapho isithombe siphrintwa; Isithombe esiphrintiwe sinokusebenza okuhle okungangeni manzi, ukukhiqizwa kabusha kombala okuhle, izendlalelo ezicebile, ukugcwala okuphezulu, i-gamut yombala obanzi, ukulungiswa kwesithombe okuphezulu, nokuzinza okuhle kombala wesampula okukhiphayo; Ingaphezulu lephepha lintekenteke futhi lifana, liyakwazi ukuzivumelanisa nomehluko ocashile phakathi kwamamodeli omkhiqizo ahlukene noyinki.
Ngokwezidingo zokusetshenziswa kwephepha lobufakazi bedijithali, lingahlukaniswa ngokwezigaba ezintathu:
Izinga lephepha lobufakazi bedijithali liyingxenye ebalulekile yokuphathwa kombala ezinhlelweni zobufakazi bedijithali. Emkhiqizweni wangempela, ukufakazela ngedijithali ngokuvamile kusebenzisa iphepha lokuphrinta le-copperplate lokulingisa. Ngakolunye uhlangothi, inokwembozo ofanele uyinki wokunyathelisa; Ngakolunye uhlangothi, inombala ofanayo wephepha elihlanganiswe nethusi elisetshenziselwa ukuphrinta, okwenza kube lula ukufeza umphumela ofanayo nemibala yokuphrinta. Ngokwezidingo zekhasimende, ukukhetha iphepha lokuqinisekisa ledijithali elifanele nelisebenzayo kanye nedatha ehlanganisiwe yokuphathwa kombala (amaphrinta, isofthiwe yokuphatha imibala, uyinki, njll.) kungakhulisa ukulingisa kwemiphumela yomkhiqizo ophrintiwe ngokuqinisekisa kwedijithali.
