Idivayisi Yokuphrinta Esezingeni Eliphezulu Yezithombe
Ezweni lokuklama imidwebo, ikhwalithi yokuphrinta ivame ukuba "umugqa wokuqeda" onquma ukuthi umsebenzi ubukeka ungowobungcweti noma awunazo imininingwane ebalulekile. Ukushintsha imibala, ama-gradient aphukile, imigqa emincane ephukile, noma umbhalo omncane, ofiphele kungonakalisa umlayezo obonakalayo oklanywe kahle. Ngakho-ke, ukukhetha idivayisi yokuphrinta efanele—kanye nesimiso sayo esisekelayo—kuyisinyathelo esibalulekile kuma-studio okuklama, ezindlini zokuphrinta, kumabhrendi, nakubadali ngabanye ngokufanayo. Lesi sihloko sixoxa ngezinhlobo zamadivayisi anikeza ikhwalithi yokuphrinta esezingeni eliphezulu yemidwebo, izici okufanele uzicabangele, kanye namathiphu okufeza imiphumela ehambisanayo neqondiwe.
1. Qonda izidingo: kusukela ekuhlolweni kuya ekukhiqizweni ngobuningi
Ngaphambi kokukhetha idivayisi, nquma ukuthi ihloselwe ukusetshenziswa ini. Izidingo zokuphrinta izithombe ngokuvamile ziwela ezigabeni ezintathu:
1) Ukuhlola (ukuhlolwa kombala): phrinta amasampula ukuqinisekisa umbala ofanele, imininingwane, kanye nokwakheka ngaphambi kokukhiqizwa ngobuningi. Kulesi sigaba, ukunemba kombala kanye nokuvumelana kuyizinto eziza kuqala.
2) Ukuphrinta kwangaphakathi: ukuphrinta izidingo zansuku zonke ezifana namaphosta amancane, izinto zokukhangisa, ukupakishwa kwezibonelo, izitika, noma izithombe zomkhiqizo. Imishini kumele ilinganisele ikhwalithi, isivinini, kanye nezindleko ngeshidi ngalinye.
3) Ukukhiqizwa kobungcweti/okukhulu: ukuphrinta amakhulu kuya ezinkulungwaneni zamashidi, noma imidiya emikhulu efana namabhanela, i-canvas, kanye nezimpawu. Kudinga imishini eqinile kakhulu, ukuphathwa kombala okuvuthiwe, kanye nokusekelwa kwezinto ezahlukahlukene.
Ngokuqonda lezi zigaba, unganquma ukuthi iphrinta ye-inkjet ye-pigment, iphrinta ye-laser yombala, iphrinta yefomethi enkulu, noma ngisho nomshini wokunyathelisa wedijithali kufanelekile yini.
2. I-inkjet ye-pigment: ukukhetha okuhle kakhulu kwemininingwane nokunemba kombala
Ngomklamo wezithombe odinga ukuhleleka okubushelelezi, ububanzi obubanzi, kanye nokukhiqizwa kombala eduze kwesibonisi sesikrini (ngokulinganiswa okufanele), amaphrinta e-inkjet asekelwe kumbala avame ukuba yisinqumo esithandwa kakhulu. Uyinki we-pigment ngokuvamile unokumelana nokufiphala okungcono kunoyinki wedayi, okwenza afanelekele izithombe zekhwalithi ephezulu, ukuphrinta kobuciko, kanye nezinto zokubonisa.
Izinzuzo eziyinhloko ze-pigment inkjet:
- Imidwebo ebushelelezi yezithombe, izithombe, kanye nemiklamo enemibala ehlukahlukene eyinkimbinkimbi.
- Imininingwane ephezulu kanye nobukhulu bokuphrinta okukhulu, okuwusizo emigqeni emincane kanye nokuthungwa okuncane.
– Ikhwalithi ezintweni ezikhethekile ezifana nephepha lobuciko obuhle, i-canvas, kanye nephepha elinobunjwa.
Izinto okufanele uziqaphele:
– Uhlelo lweyinki (isb., imibala engu-6, 8, 10, noma ngisho engu-12) luthinta i-gamut kanye ne-gradation. Uma iziteshi zemibala eziningi, kulapho ukushintsha kombala kubushelelezi khona futhi kulapho ukukhiqizwa kabusha kucebile khona.
– Qinisekisa ukwesekwa kwephrofayili ye-ICC kwenhlanganisela yephrinta-iyinki-iphepha ukuze uthole imibala enembile kakhudlwana.
3. Iphrinta ye-laser enemibala: esheshayo, ehlanzekile, futhi ehambisana nezidingo zehhovisi zokudala
Uma udinga ukuphrinta izinto zokwethula, izincwajana ezilula, ama-mockup asheshayo, noma amadokhumenti ezithombe anombhalo oyinhloko, iphrinta ye-laser enemibala ingaba yisisombululo. Ama-laser ahamba phambili ngesivinini, umbhalo obukhali, kanye nokuvumelana kweshidi neshidi, ikakhulukazi kumavolumu aphakathi.
Izinzuzo zamaphrinta e-laser anombala:
- Kuyashesha futhi kusebenza kahle ekuphrinteni amakhasi amaningi.
– Umbhalo namavektha (imigqa, imidwebo) kubukeka kucacile.
– Izinkinga ezimbalwa njengemibhobho evalekile ngezinye izikhathi ezenzeka ngama-inkjet uma zingasetshenziswa njalo.
Imikhawulo yayo:
– Kwezinye izinhlobo, ukuhlelwa kwezithombe kungaba bushelelezi kancane kune-inkjet, ikakhulukazi ezindaweni ezinethunzi noma zesikhumba.
– Izinketho zemidiya ekhethekile (ubuciko obuhle) zivame ukulinganiselwa kakhulu.
4. Iphrinta yefomethi enkulu (i-LFP): yamaphosta, amabhanela, kanye nemisebenzi emikhulu
Ngezidingo zezithombe ezinkulu—amaphosta e-A1/A0, izimpawu zangaphakathi, imibukiso, ngisho nokuphrinta ngekhanvasi—amaphrinta amakhulu ayithuluzi elisetshenziswa kakhulu. Amaphrinta amakhulu atholakala ngezindlela ezahlukene zobuchwepheshe beyinki: udayi, umbala, i-eco-solvent, i-solvent, i-latex, kanye ne-UV.
Umhlahlandlela osheshayo wokukhetha uyinki we-LFP:
– I-pigment (emanzi): ilungele amaphosta angaphakathi, izithombe, kanye nobuciko obuhle, inikeza imiphumela ebukhali nemibala ecebile. Ayifaneleki kangako ukusetshenziswa ngaphandle ngaphandle kwe-lamination.
– Isinyibilikisi semvelo/isinyibilikisi: siqinile ezintweni ze-vinyl nasekusetshenzisweni kwangaphandle, simelana nesimo sezulu, sifanelekile ezimpawini.
– I-Latex: ukomisa ngokushesha, inobungani nemvelo, ifanele ukusetshenziswa ngaphakathi/ngaphandle.
– I-UV: ingaphrinta ngqo ezintweni eziqinile njenge-acrylic, izinkuni, noma ibhodi le-foam, imiphumela iqinile kakhulu futhi ihlala isikhathi eside.
Ngaphandle kweyinki, naka ububanzi bokuphrinta (24”, 44”, 60”), ikhono lokugoqa-ukuya-ekugoqeni, kanye nokusekela ukusika uma ukhiqiza izitikha noma amadeshi.
5. Umshini wokucindezela wedijithali: indinganiso yesimanje yokukhiqiza ukuphrinta yekhwalithi kanye nomthamo.
Kumaphrinta noma ama-studio akhiqiza izinto ezinkulu zezentengiselwano (amakhathalogi, izincwadi, izincwajana zekhwalithi ephezulu, ukupakishwa okulula), imishini yokunyathelisa yedijithali inikeza inhlanganisela yekhwalithi ephezulu kanye nokusebenza kahle. Le mishini iphezulu kakhulu: ishesha kune-inkjet yedeskithophu, ihambisana kakhulu ezinkulungwaneni zamashidi, futhi imvamisa inezinketho zokuqeda ezihlanganisiwe.
Izinzuzo zomshini wokunyathelisa wedijithali:
– Ukuhambisana kombala phakathi kwamaqoqo kugcinwa kangcono (ngokusebenza okulungile).
- Isekela izinhlobo ezahlukene zephepha kanye nokuqedwa.
- Ilungele umsebenzi onezinsuku zokugcina eziqinile kanye nenani elikhulu.
Kodwa-ke, izindleko zokutshalwa kwezimali kanye nokusebenza ziphakeme, ngakho-ke ngokuvamile zifanelekile emabhizinisini amakhulu okunyathelisa noma okunyathelisa ngaphakathi.
6. Izici ezibalulekile zekhwalithi yokuphrinta: hhayi nje isinqumo se-DPI
Abantu abaningi bagxile kuzinombolo ze-DPI, yize ikhwalithi yokuphrinta kwesithombe inqunywa yizici eziningana ezihlobene:
1) Ukunemba kombala nokuphathwa kombala
Ngaphandle kokulinganiswa kwemonitha kanye namaphrofayili e-ICC, okuphrintiwe kungahluka kakhulu ekwakhiweni. Uhlelo oluhle lokuphatha imibala luqinisekisa ukuthi lokho okubonayo kufana kakhulu nalokho okuphrintiwe.
2) Uhlobo lweyinki kanye nenani leziteshi zombala
Uyinki we-pigment oneziteshi eziningi (isb., i-gray eyengeziwe noma i-cyan/magenta ekhanyayo) usiza ekunciphiseni okusanhlamvu futhi ulungise ukuhleleka kwemigqa.
3) Ikhwalithi yemidiya (iphepha/izinto eziphrintiwe)
Iphepha elimboziwe, elingacwebezeli, elicwebezelayo, elinobuciko obuhle, noma eliyi-canvas linezici ezihlukile zokumunca. Le ndlela ithinta kakhulu ukugqama, ukugcwala, kanye nokucija.
4) Isofthiwe ye-RIP (yezidingo zobungcweti)
Emisebenzini emikhulu neyinkimbinkimbi, i-RIP (Raster Image Processor) isiza ngokulawula imibala, ukuhlola, ukwakha izidleke, kanye nokusebenza kahle kokukhiqiza.
5) Ukugcinwa kwedivayisi nokuzinza
Ukuhlolwa kwe-nozzle, ukuhlanza ikhanda, izinga lokushisa/umswakama wegumbi, kanye nokugcinwa kwezinto kuthinta ukuhambisana kwemiphumela.
7. Amadivayisi asekelayo avame ukukhohlwa: ama-calibrators kanye nezinsimbi zokulinganisa umbala
Ukuze kufezwe ngempela ikhwalithi ephezulu yokuphrinta, idivayisi yokuphrinta idinga "ukubhangqwa" namathuluzi asekelayo:
– I-monitor calibrator: iqinisekisa ukuthi isikrini sibonisa imibala enembile. Ngaphandle kwayo, usebenza ngesibonisi esingakhohlisa.
– I-Spectrophotometer: isiza ukudala nokuqinisekisa amaphrofayili e-ICC, abalulekile ekuqinisekiseni nasekukhiqizeni imisebenzi.
– Ibhokisi lokukhanyisa (ongakukhetha): ukuhlola imiphumela yokuphrinta ezimweni zokukhanya ezijwayelekile, ukuze ukuhlolwa kombala kuhambisane.
Ukutshalwa kwezimali okuncane ekulinganisweni kuvame ukuba nomthelela omkhulu ekhwalithini futhi kunciphisa izindleko zamaphutha okuhlola.
8. Amathiphu awusizo okukhetha amadivayisi okuphrinta asezingeni eliphezulu ezithombe
Nazi ezinye izeluleko ezingasiza:
1) Nquma umkhiqizo oyinhloko: izithombe/ubuciko obuhle, amaphosta, izinto zasehhovisi, noma izimpawu zangaphandle. Lokhu kuzokuqondisa ekukhetheni kwakho ubuchwepheshe beyinki kanye nohlobo lomshini.
2) Hlola ukutholakala kwamaphrofayili e-ICC kumaphepha owasebenzisa njalo.
3) Hlola amasampula okuphrinta kumiklamo emele umsebenzi wakho: faka izithombe, ama-gradients, imibala yomkhiqizo, umbhalo omncane, kanye nezinto ze-vector.
4) Bala izindleko ngokuphrinta ngakunye (inki/ithoni, iphepha, ukulungiswa), hhayi nje intengo yomshini.
5) Cabanga ngesevisi yangemva kokuthengisa: ukutholakala kwezingxenye ezisele, iwaranti, kanye nokusekelwa kobuchwepheshe kunquma kakhulu isikhathi sokungasebenzi.
6) Lungisa ukuhamba komsebenzi wombala: lungisa i-monitor, setha isikhala sombala (isb. i-Adobe RGB yezithombe), bese usebenzisa ukuhlolwa ngaphambi kokukhiqiza.
I-Penutup
Ukuphrinta ihluzo ezisezingeni eliphezulu akukhona nje kuphela ngamaphrinta abizayo noma imininingwane ephezulu ye-DPI. Ikhwalithi engcono kakhulu ivela ekuhlanganisweni okulungile kohlobo lwephrinta (i-inkjet ye-pigment, i-laser, ifomethi enkulu, noma umshini wokunyathelisa wedijithali), uhlelo lwe-ink, imidiya yokunyathelisa, kanye nokuphathwa kombala okuhlelekile. Ngokukhetha imishini efanele izidingo zakho nokusungula ukuhamba komsebenzi okuvumelanayo, ungakhiqiza ihluzo ezibukhali nezinemibala ezimele imiklamo yakho njengoba nje uyicabanga—kungaba ukusetshenziswa komuntu siqu, iphothifoliyo yobungcweti, noma ukukhiqizwa kwezentengiselwano.
Uma uthanda, ngingakusiza ukuncoma uhlobo olufanele kakhulu lwedivayisi ngokusekelwe ezidingweni zakho (usayizi wokuphrinta, uhlobo lwemidiya, ivolumu yanyanga zonke, kanye nesabelomali).
