Intuthuko kwezobuchwepheshe kumaphrinta nama-inki ibe yisihluthulelo ekukhuleni kwemakethe, futhi kusenendawo eningi yokukhula maduze.
Inothi Lomhleli: Engxenyeni 1 yochungechunge lwethu lwezimbozo zodonga ezinyatheliswe ngedijithali, “Izimbozo Zodonga Ziyavela Njengethuba Elikhulu Lokunyathelisa Ngedijithali,” abaholi bemboni baxoxe ngokukhula kwengxenye yezimbozo zodonga. Ingxenye 2 ibheka izinzuzo eziqhuba lokho kukhula, kanye nezinselele okudingeka zinqotshwe ukuze kuqhutshekwe nokukhula kwe-inkjet.
Kungakhathaliseki ukuthi imakethe injani, ukuphrinta kwedijithali kunikeza izinzuzo ezithile ezingokwemvelo, ikakhulukazi ikhono lokwenza ngezifiso imikhiqizo, izikhathi zokushintsha ngokushesha kanye nokukhiqiza ukugijima okuncane ngempumelelo enkulu. Isithiyo esikhulu ukufinyelela osayizi bokugijima okuphezulu ngendlela engabizi kakhulu.
Imakethe yezimbozo zodonga eziphrintiwe ngedijithali ifana kakhulu kulezo zici.
UDavid Lopez, umphathi womkhiqizo, i-Professional Imaging, i-Epson America, ukhombe ukuthi ukuphrinta kwedijithali kunikeza izinzuzo eziningana emakethe yokumboza udonga, okuhlanganisa ukwenza ngokwezifiso, ukuguquguquka, kanye nokukhiqiza.
“Ukuphrinta kwedijithali kuvumela imiklamo engenziwa ngokwezifiso kakhulu ezinhlotsheni ezahlukahlukene ezihambisanayo futhi kuqeda isidingo sezinqubo zokusetha zendabuko, njengokwenza amapuleti noma ukulungiswa kwesikrini, ezinezindleko eziphezulu zokusetha,” kusho uLopez. “Ngokungafani nezindlela zokuphrinta zendabuko, ukuphrinta kwedijithali kuyabiza kakhulu futhi kunikeza izikhathi ezisheshayo zokushintsha kokuphrinta okufushane. Lokhu kwenza kube wusizo ekukhiqizeni inani elincane lezembozo zodonga ezenziwe ngokwezifiso ngaphandle kwesidingo senani elikhulu le-oda.”
UKitt Jones, umphathi wezokuthuthukiswa kwebhizinisi nokudalwa ngokubambisana, uRoland DGA, uphawule ukuthi kunezinzuzo eziningi ezilethwa ukuphrinta kwedijithali emakethe yezimbozo zodonga.
“Lobu buchwepheshe abudingi isitokwe, buvumela ukwenziwa ngokwezifiso ngamaphesenti ayi-100 ngokuklama, futhi buvumela izindleko eziphansi kanye nokulawula okungcono ekukhiqizeni kanye nesikhathi sokushintsha,” kwenezela uJones. “Ukwethulwa kwe-Dimensor S, omunye wemikhiqizo emisha kakhulu etholakalayo kuzinhlelo zokusebenza ezinjalo, kuletha inkathi entsha yokuthungwa okwenziwe ngokwezifiso kanye nokukhiqizwa kokuphrinta lapho kudingeka okuvumela hhayi nje kuphela umkhiqizo oyingqayizivele, kodwa futhi nembuyiselo ephezulu ekutshalweni kwezimali.”
UMichael Bush, umphathi wezokuxhumana kwezokumaketha, i-FUJIFILM Ink Solutions Group, uphawule ukuthi i-inkjet kanye nobuchwepheshe bedijithali obubanzi kufaneleka kakhulu ekukhiqizeni amaphrinta odonga asebenza isikhathi esifushane futhi aklanyelwe ngokukhethekile.
“Izimbozo zodonga ezinesihloko nezenzeke ngendlela ekhethekile zithandwa kakhulu ekuhlobiseni amahhotela, izibhedlela, izindawo zokudlela, izindawo zokuthengisa kanye namahhovisi,” kusho uBush. “Izidingo zobuchwepheshe ezibalulekile zezimbozo zodonga kulezi zindawo zangaphakathi zifaka phakathi izimbozo ezingenaphunga/ezingenaphunga eliningi; ukumelana nokuklwebheka ngokomzimba ngenxa yokuklwebheka (njengesibonelo abantu baklwebheka odongeni emaphaseji, ifenisha ithinta izindonga ezindaweni zokudlela, noma amasudikethi aklwebheka odongeni emakamelweni ehhotela); ukugezwa kanye nokuqina kokufakwa kwesikhathi eside. Kulolu hlobo lwezinhlelo zokusebenza zokuphrinta, kukhona uhla lwemibala yenqubo yedijithali kanye nomkhuba okhulayo wokufaka izinqubo zokuhlobisa.
“Ubuchwepheshe be-eco-solvent, i-latex, kanye ne-UV busetshenziswa kabanzi futhi bonke bufanelekela ukumbozwa kodonga, ngabunye bunezinzuzo kanye nemikhawulo yalo,” kusho uBush. “Isibonelo, i-UV inokumelana okuhle kakhulu nokuguguleka kanye namakhemikhali, kodwa kunzima kakhulu ukufeza ukuphrinta okunephunga eliphansi kakhulu nge-UV. I-Latex ingaba nephunga eliphansi kakhulu kodwa ingaba nokumelana okuncane kokukhuhla futhi ingadinga inqubo yesibili yokulamination ukuze kusetshenziswe ukuguguleka okubalulekile. Ubuchwepheshe be-hybrid UV/aqueous bungabhekana nesidingo sokuphrinta okunephunga eliphansi kanye nokuqina.
“Uma kukhulunywa ngokukhiqizwa kwezithombe zangemuva ngobuningi bezimboni ngokukhiqiza okukodwa, ukulungela ubuchwepheshe bedijithali ukuhambisana nokukhiqiza kanye nezindleko zezindlela ze-analog kuyisici esibalulekile,” kuphetha uBush. “Ikhono lokukhiqiza imibala ebanzi kakhulu, imibala yamabala, imiphumela ekhethekile, kanye nokuqedwa okufana nezinsimbi, ama-pearlescent kanye ne-glitter, okuvame ukudingeka ekwakhiweni kwephepha lodonga, nakho kuyinselele yokunyathelisa kwedijithali.”
“Ukuphrinta kwedijithali kuletha izinzuzo eziningana kulolu hlelo lokusebenza,” kusho uPaul Edwards, iPhini likaMongameli wesigaba sedijithali e-INX International Ink Co. “Okokuqala, ungaphrinta noma yini kusukela kukhophi eyodwa yesithombe ngentengo efanayo neyi-10,000. Izinhlobonhlobo zezithombe ongazakha zikhulu kakhulu kunenqubo ye-analog futhi ukwenziwa ngokwezifiso kungenzeka. Ngokuphrinta kwedijithali, awunqunyelwe ngokwesilinganiso sobude besithombe obuphindaphindwayo njengoba ubungenza nge-analog. Ungaba nokulawula okungcono kwempahla futhi ukuphrinta kuya ku-oda kungenzeka.”
U-Oscar Vidal, umqondisi womhlaba wonke we-HP wefomethi enkulu ye-HP, uthe ukuphrinta kwedijithali kushintshe imakethe yokumboza udonga ngokunikeza izinzuzo eziningana ezibalulekile.
"Enye yezinzuzo ezibaluleke kakhulu yikhono lokwenza ngezifiso imiklamo, amaphethini, kanye nezithombe uma kudingeka. Leli zinga lokwenza ngezifiso lifiseleka kakhulu kubaklami bangaphakathi, abaklami bezakhiwo, kanye nabanini bezindlu abafuna izimbozo zodonga ezihlukile," kusho uVidal.
“Ngaphezu kwalokho, ukuphrinta kwedijithali kwenza kube lula ukushintsha ngokushesha, kususe ukusethwa okude okudingekayo ngezindlela zokuphrinta zendabuko,” kwenezela uVidal. “Kuyabiza futhi uma kwenziwa imisebenzi emincane yokukhiqiza, okwenza kube ukukhetha okuhle kwamabhizinisi nabantu ngabanye abadinga inani elilinganiselwe lezimbozo zodonga. Ukuphrinta kwekhwalithi ephezulu okufezwa ngobuchwepheshe bedijithali kuqinisekisa imibala egqamile, imininingwane ebukhali, kanye namaphethini ayinkimbinkimbi, okuthuthukisa ukubukeka okuphelele.
“Ngaphezu kwalokho, ukuphrinta kwedijithali kunikeza ukuguquguquka, njengoba kungenziwa ezintweni ezahlukahlukene ezifanele ukumbozwa odongeni,” kuphawula uVidal. “Lokhu kuguquguquka kuvumela ukukhethwa okuhlukahlukene kokuthungwa, ukuqeda, kanye nezinketho zokuqina. Okokugcina, ukuphrinta kwedijithali kunciphisa imfucuza ngokuqeda isitokwe esiningi nokunciphisa ingozi yokukhiqizwa ngokweqile, njengoba ukuhlobisa odongeni kungaphrintwa uma kudingeka.”
Izinselele ku-Inkjet Yezimbozo Zodonga
UVidal waphawula ukuthi ukuphrinta kwedijithali kwadingeka kunqobe izinselele eziningana ukuze kuqinisekiswe ukuthi kukhona emakethe yokuhlobisa udonga.
“Ekuqaleni, kwakunzima ukuhambisana nekhwalithi yezindlela zokuphrinta zendabuko njengokuphrinta kwesikrini noma ukuphrinta nge-gravure,” kusho uVidal. “Kodwa-ke, intuthuko kwezobuchwepheshe bokuphrinta kwedijithali, okuhlanganisa nokunemba kombala okuthuthukisiwe kanye nesisombululo esiphezulu, kwenze ukuthi ukuphrinta kwedijithali kuhlangabezane futhi kudlule amazinga ekhwalithi embonini. Isivinini sasiyinye inselele, kodwa ngenxa yezixazululo zokwenza ngokuzenzakalelayo kanye nokuphrinta okuhlakaniphile njenge-HP Print OS, izinkampani zokuphrinta zingavula ukusebenza kahle okungakaze kubonwe ngaphambili - njengokuhlaziywa kwedatha yokusebenza noma ukususa izinqubo eziphindaphindayo nezithatha isikhathi.
“Enye inselele kwakuwukuqinisekisa ukuqina, njengoba izembozo zodonga kudingeka zimelane nokuguguleka, ukudabuka, nokushabalala,” kusho uVidal. “Izinto ezintsha ezakhiweni zoyinki, njenge-inki ze-HP Latex – ezisebenzisa i-Aqueous Dispersion Polymerization ukukhiqiza izembozo ezihlala isikhathi eside – ziye zabhekana nale nselele, zenza izembozo zedijithali zamelana kakhulu nokushabalala, umonakalo wamanzi, kanye nokuguguleka. Ngaphezu kwalokho, ukuphrinta kwedijithali kwadingeka kuqinisekise ukuhambisana nezinhlobo eziningi zezembozo ezisetshenziswa ezembozweni zodonga, okuye kwafezwa nangokuthuthuka kwezembozo zoyinki kanye nobuchwepheshe bephrinta.
“Okokugcina, ukuphrinta kwedijithali kuye kwaba ngcono kakhulu ngokuhamba kwesikhathi, ikakhulukazi kumaphrojekthi esikhashana noma enziwe ngokwezifiso, okwenza kube inketho efanelekile emakethe yokumboza udonga,” kuphetha uVidal.
UJones weRoland DGA uthe izinselelo ezinkulu kube ukudala ulwazi ngabaphrinta kanye nezinto zokwakha, ukuqinisekisa ukuthi amakhasimende angaba khona ayaqonda inqubo yokuphrinta iyonke, kanye nokuqinisekisa ukuthi abasebenzisi banenhlanganisela efanele yephrinta, uyinki, kanye nemidiya ukusekela izidingo zamakhasimende abo.
“Ngenkathi lezi zinselele ezifanayo zisekhona ngezinga elithile kubaklami bangaphakathi, abaklami bezakhiwo, nabakhi, sibona intshisekelo ekhulayo kule makethe yokuletha ukunyathelisa kwedijithali ngenxa yezizathu ezishiwo ngaphambilini - amakhono okukhiqiza ahlukile, izindleko eziphansi, ukulawula okungcono, inzuzo eyengeziwe,” kusho uJones.
“Kunezinselele eziningana,” kuphawula u-Edwards. “Akuwona wonke ama-substrate afanelekela ukunyatheliswa kwedijithali. Izindawo zingase zimunce kakhulu, futhi ukususa uyinki esakhiweni kungase kungavumeli amaconsi ukuba asakazeke kahle.
“Inselele yangempela ukuthi ukukhetha izinto/izingubo ezisetshenziselwa ukuphrinta kwedijithali kumele kukhethwe ngokucophelela,” kusho u-Edwards. “Iphepha lodonga lingaba nothuli oluncane ngemicu ekhululekile, futhi lokhu kudingeka kugcinwe kude nemishini yokuphrinta ukuqinisekisa ukuthembeka. Izindlela ezahlukene zingasetshenziswa ukubhekana nalokhu ngaphambi kokuba kufinyelele kuphrinta. Uyinki kumele ube nephunga eliphansi ngokwanele ukuze usebenze kulolu hlelo lokusebenza, futhi ubuso beyinki uqobo kumele bumelane nokuklwebheka ngokwanele ukuqinisekisa izici ezinhle zokuguguleka nokuklebhuka.
“Ngezinye izikhathi ijazi le-varnish liyasetshenziswa ukuze kuthuthukiswe ukumelana kweyinki uqobo,” kusho u-Edwards. “Kufanele kuqashelwe ukuthi ukuphathwa komkhiqizo ngemva kokuphrinta kumele kucatshangelwe. Imiqulu yezinto zokwakha zezinhlobo ezahlukene zezithombe nayo idinga ukulawulwa nokuhlanganiswa, okwenza kube nzima kakhulu kwedijithali ngenxa yenani elikhulu lezinhlobo zokuphrinta.”
“Ukunyathelisa ngedijithali kubhekane nezinselele eziningana ukuze kufike lapho kukhona namuhla; okuvelele ukuqina komkhiqizo kanye nokuphila isikhathi eside,” kusho uLopez. “Ekuqaleni, imiklamo ephrintiwe ngedijithali yayingagcini ukubukeka kwayo njalo futhi kwakukhona ukukhathazeka mayelana nokunyamalala, ukufiphala kanye nokuklwebheka, ikakhulukazi ezimbozweni zodonga ezibekwe ezindaweni ezishisayo noma ezindaweni ezinabantu abaningi. Ngokuhamba kwesikhathi, ubuchwepheshe buthuthukile futhi namuhla, lezi zinkinga zincane kakhulu.
“Abakhiqizi bathuthukise uyinki oqinile kanye nehadiwe ukuze balwe nalezi zinkinga,” kusho uLopez. “Isibonelo, amaphrinta e-Epson SureColor R-Series asebenzisa uyinki we-resin we-Epson UltraChrome RS, isethi yeyinki eyakhiwe yi-Epson ukuze isebenze ne-Epson PrecisionCore MicroTFP printhead, ukuze ikhiqize umkhiqizo oqinile, omelana nokuklwebheka. Uyinki we-resin unezakhiwo ezimelana nokuklwebheka ezenza kube yisisombululo esifanele sezindonga ezimbozwe ezindaweni ezinabantu abaningi.”
