Momwe Mungasankhire Chida Chosindikizira Zithunzi Zokongola Kwambiri
Kusindikiza zithunzi zowoneka bwino sikuti ndi nkhani yoti "mupeze fayilo yabwino ndikusindikiza." Zotsatira zake, mitundu yolondola, ndi tsatanetsatane wake wopanda cholakwika zimakhudzidwa kwambiri ndi zida zomwe mwasankha, kuyambira chosindikizira ndi mtundu wa inki mpaka pepala ndi zida zothandizira monga kuwerengera monitor. Nkhaniyi ikufotokoza momwe mungasankhire zida zoyenera zosindikizira zithunzi zowoneka bwino kuti mupeze zotsatira zabwino, kaya za kujambula zithunzi, zojambula, kapangidwe ka zithunzi, kapena zaluso.
1. Choyamba mvetsetsani zosowa zanu zosindikizira
Musanagule kapena kugwiritsa ntchito chida china chake, fotokozani momveka bwino zomwe mukufuna kusindikiza. Mafunso ena oti muyankhe:
- Kukula kwa chithunzi: Kodi mudzasindikiza 10R, A4, A3, A2, kapena kukula kwa positi?
- Cholinga chosindikizira: Pa zowonetsera pakhoma, ma portfolio, malonda a zithunzi, makatalogu azinthu, kapena zolemba chabe?
– Zosindikiza: Pepala lowala la zithunzi, losawoneka bwino, pepala lojambula bwino, nsalu, kapena pepala wamba?
– Kuchuluka kwa zosindikiza: Kodi mumasindikiza zambiri pafupipafupi (kupanga) kapena nthawi zina?
Zofunikira izi zimatsimikiza kalasi ya chosindikizira, mtundu wa inki, ndi zinthu zofunika. Mwachitsanzo, kusindikiza zithunzi za chiwonetsero kudzafuna zida zosiyana ndi kusindikiza zithunzi za pempho la ofesi.
2. Samalani ndi mawonekedwe ndi mtundu wa chosindikizira.
Anthu ambiri amaganizira kwambiri nambala ya DPI (madontho pa inchi). Ngakhale kuti n'kofunika, si chizindikiro chokhacho. Makina osindikizira zithunzi nthawi zambiri amapereka ma resolution apamwamba monga 4800 × 1200 dpi kapena kupitirira apo, koma khalidwe lomaliza limakhudzidwanso ndi njira yoyika madontho, mtundu wa mutu wa chosindikizira, ndi mitundu/ma inki omwe amagwiritsidwa ntchito.
Kuti musindikize zithunzi zapamwamba kwambiri, sankhani chosindikizira chomwe:
- Yopangidwira makamaka kusindikiza zithunzi kapena zaluso
- Ali ndi ulamuliro wabwino pa tsatanetsatane wa ma grading ndi kuthwa
- Imathandizira mawonekedwe apamwamba kwambiri (chithunzi chabwino kwambiri/chosalala)
Komabe, kumbukirani kuti fayilo yokhala ndi mawonekedwe apamwamba iyeneranso kukhala yokwanira. Pazosindikiza zakuthwa, muyezo wamba ndi 300 PPI pa kukula komaliza kosindikiza. Mwachitsanzo, chosindikizira cha A4 (8,27 × 11,69 mainchesi) chimafuna kukula kwa chithunzi cha ma pixel pafupifupi 2480 × 3508.
3. Sankhani mtundu wa chosindikizira: Chithunzi cha inkjet vs laser
Pa kusindikiza zithunzi kwapamwamba, ma inkjet printer (makamaka ma photo inkjet) nthawi zambiri amakhala chisankho chabwino kwambiri. Zifukwa zazikulu ndi izi:
- Wokhoza kupanga mitundu yosalala
- Tsatanetsatane wa chithunzi chowala
- Chithandizo chachikulu cha zithunzi ndi mapepala opangidwa mwaluso
Ngakhale kuti makina osindikizira a laser ndi abwino kwambiri pa zolemba ndi zikalata zachangu, nthawi zambiri sagwira ntchito pazithunzi pankhani ya kuzama kwa utoto ndi kusintha kwa gradient, ngakhale kuti mitundu ina yapamwamba ndi yabwino mokwanira pa zosowa zina.
Ngati cholinga chanu ndi kusindikiza zithunzi kapena zojambulajambula zapamwamba kwambiri, sankhani chosindikizira zithunzi cha inkjet.
4. Chongani kuchuluka ndi mtundu wa inki (dongosolo la inki)
Chimodzi mwa zinthu zazikulu zomwe zimapangitsa kuti zinthu zisindikizidwe bwino ndi makina a inki. Makina osindikizira zithunzi nthawi zambiri amagwiritsa ntchito mitundu yambiri ya inki kuposa CMYK yoyambira. Inki ikachuluka, imasalala bwino ndipo mitunduyo imakhala yolondola kwambiri.
Zinthu zina zofunika kuziganizira:
– CMYK (mitundu 4): yokwanira kusindikiza, koma nthawi zambiri si yosalala mokwanira kuti ijambulidwe zithunzi.
– Mitundu 6 (monga kuwala kowonjezera kwa cyan ndi kuwala kwa magenta): yabwino kwambiri pazithunzi.
– mitundu 8–12 (imvi yowonjezera, imvi yopepuka, yofiira/buluu/lalanje, ndi zina zotero): yabwino kwambiri pa zaluso ndi kujambula zithunzi zaukadaulo.
Kupatula kuchuluka kwake, samalaninso mtundu wa inki:
– Inki yopangidwa ndi utoto: mitundu yake ndi “yowala” komanso yakuthwa, yoyenera zithunzi zowala, koma kukana kwa madzi/UV kungakhale kochepa.
– Inki yopangidwa ndi utoto: yolimba kwambiri, yoyenera zojambulajambula ndi zowonetsera, nthawi zambiri imakhala yokhazikika komanso yosatha.
Ngati mukusindikiza kuti muwonetse kapena kugulitsa, inki ya utoto nthawi zambiri ndiyo njira yabwino kwambiri.
5. Onetsetsani kuti kukula kwa pepala ndi njira ya pepala zimathandiza.
Si ma printer onse omwe amathandiza mapepala okhuthala kapena akuluakulu. Pa kusindikiza kwapamwamba, mwina mungafune kugwiritsa ntchito mapepala okhuthala kapena apamwamba. Chifukwa chake, chonde dziwani:
- Kukula kwakukulu kwa mapepala: A4, A3, A3+, mpaka A2.
- Chithandizo chosindikiza chopanda malire: chofunikira posindikiza zithunzi zopanda malire oyera.
– Chakudya chakumbuyo/chakutsogolo: chothandiza pa pepala lokhuthala, pepala laluso, kapena zinthu zapadera.
- Kutha kusindikiza pa zinthu zina monga nsalu kapena pepala la zaluso lokhala ndi mawonekedwe.
Pepala lapamwamba nthawi zambiri limafuna njira yowongoka bwino kuti lipewe kupindika kapena kutsekeka.
6. Sankhani pepala loyenera cholinga ndi khalidwe la chithunzicho.
Mawonekedwe apamwamba adzawoneka bwino kwambiri ngati pepalalo likugwirizana ndi tsatanetsatane. Pepala loipa lingayambitse zithunzi zosawoneka bwino, kutayika kwa tsatanetsatane, kapena mitundu yolakwika.
Mitundu yodziwika bwino ya mapepala:
– Wonyezimira: mitundu yakuthwa, kusiyana kwakukulu, yoyenera zithunzi.
– Semi-gloss/Luster: yosagwira zala zambiri, imakhalabe yakuthwa, yomwe ndi yokondedwa ndi ojambula zithunzi ambiri.
– Wosaoneka bwino: mawonekedwe ofewa, oyenera zithunzi ndi mapangidwe ang'onoang'ono.
– Pepala la zaluso (nsalu ya thonje, yopangidwa ndi mawonekedwe): la zojambulajambula, mawonekedwe apamwamba, oyenera inki ya utoto.
Kupatula mtundu wake, samalani ndi grammage (monga 200–300 gsm) komanso momwe pepalalo likugwirizana ndi chosindikizira chanu.
7. Kusamalira mitundu: chowunikira, kuwerengera, ndi mbiri ya ICC
Kawirikawiri zosindikiza zimasiyana ndi zowonetsera pazenera. Chifukwa chake nthawi zambiri chimakhala kusasamalira bwino mitundu. Pa kusindikiza kwapamwamba, kulondola kwa mitundu ndikofunikira monga momwe kuwunikira.
Zida zothandizira kasamalidwe ka mitundu:
- Chowunikira chokhala ndi mitundu yosiyanasiyana (osachepera sRGB ndi yabwino, makamaka imathandizira AdobeRGB/DP3)
- Choyezera choyezera (colorimeter) kuti chiwonetsedwe nthawi zonse
– Mbiri ya ICC yophatikiza chosindikizira–inki–pepala
Gwiritsani ntchito mbiri ya ICC ya wopanga mapepala kapena pangani yanu ngati n'kotheka. Izi zidzaonetsetsa kuti mitundu yomwe ikubwerayo ili pafupi ndi kapangidwe koyambirira, makamaka pantchito yaukadaulo.
8. Ganizirani mapulogalamu osindikizira ndi njira yogwirira ntchito
Chosindikizira chabwino chiyenera kuthandizira kuti ntchito iyende bwino. Mutha kugwiritsa ntchito mapulogalamu monga Adobe Photoshop/Lightroom, Affinity Photo, kapena mapulogalamu omangidwa mkati mwa chosindikizira kuti muyang'anire:
- kukula ndi kukula
- kukulitsa zinthu zomwe zimachokera
- cholinga chowonetsera (chowona/choyerekeza cha colorimetric)
- kuyeretsa mofewa musanasindikize
Kuyeretsa kofewa kumakuthandizani "kutsanzira" chosindikizidwa pa chowunikira kutengera mbiri ya ICC, kuti muthe kukonza mtundu kapena kuwala musanawononge pepala ndi inki.
9. Werengani ndalama zogwirira ntchito: inki, kukonza, ndi kulimba.
Chosindikizira chotsika mtengo sichinthu chotsika mtengo kwenikweni. Pakusindikiza kwapamwamba, inki ndi pepala zimatha kukhala ndalama zazikulu. Taganizirani izi:
- mtengo ndi mphamvu ya katiriji/thanki
- kugwiritsa ntchito inki poyeretsa/kukonza
- kupezeka kwa inki yoyambirira ndi chithandizo
- kukana kusindikiza (kukana kutha)
Ngati mumasindikiza pafupipafupi, chosindikizira chokhala ndi makina a inki ogwira ntchito bwino komanso okhazikika chingakhale chopindulitsa kwambiri pakapita nthawi.
10. Malangizo osankha zida kutengera momwe zimagwiritsidwira ntchito
Kuti zikhale zothandiza kwambiri, nayi kalozera waufupi malinga ndi zosowa zanu:
1. Kusindikiza zithunzi kunyumba (nthawi zina A4/A3)
Sankhani inki ya zithunzi yamitundu 6, yothandiza pepala lopanda malire, lowala/lonyezimira.
2. Chithunzi cha wojambula zithunzi kapena wojambula zithunzi (nthawi zonse A3+)
Sankhani chosindikizira cha zithunzi chokhala ndi inki ya utoto wamitundu 8+, chothandizira pepala laluso, komanso njira yolimba ya pepala.
3. Zojambulajambula zosindikizidwa zogulitsa
Ikani patsogolo inki ya utoto, thonje la pepala laluso, kasamalidwe ka mitundu + mbiri ya ICC, komanso ganizirani za satifiketi yosungira zinthu zakale.
4. Ofesi ikufuna koma ikufuna kuti chithunzicho chikhale chowala
Inki ya utoto wabwino ingathandize, koma onetsetsani kuti pepalalo ndi loyenera ndipo kukula kwa fayilo ndikokwanira.
Kutseka
Kusankha chipangizo chosindikizira zithunzi chapamwamba kumatanthauza kuonetsetsa kuti unyolo wonse wopanga—mafayilo, chosindikizira, inki, pepala, ndi kasamalidwe ka mitundu—umagwira ntchito mogwirizana. Chosindikizira chapamwamba chokha sichikwanira ngati inki siili yolondola kapena pepala silikugwirizana ndi tsatanetsatane. Mwa kumvetsetsa zosowa zanu, kusankha chosindikizira cha inkjet choyenera cha zithunzi, kuphatikiza inki ndi pepala logwirizana, ndikukhazikitsa kasamalidwe koyenera ka mitundu, mutha kupeza zosindikiza zakuthwa, zolemera, komanso zooneka ngati akatswiri.
Ngati mukufuna, ndingakuthandizeni kulangiza zofunikira kwambiri pa zipangizo kutengera: kukula kwa chosindikizira (A4/A3/A2), bajeti, kuchuluka kwa kusindikiza pamwezi, ndi mtundu wa chithunzi chomwe mumasindikiza (zithunzi, zithunzi, mapangidwe).
