Kodi chromatic aberration ndi chiyani?

Chromatic aberration imatanthawuza kusiyana kwa mtundu. M'moyo watsiku ndi tsiku, nthawi zambiri timanena kuti kusiyana kwa mitundu kumatanthawuza zochitika za kusagwirizana kwa mtundu pamene diso la munthu likuwona mankhwala. Mwachitsanzo, mu makampani osindikizira, kusiyana kwa mtundu pakati pa nkhani yosindikizidwa ndi chitsanzo chokhazikika choperekedwa ndi kasitomala.
M'makampani ndi malonda, ndikofunikira kwambiri kuyesa kusiyana kwa mtundu wazinthu molondola. Komabe, zinthu zambiri, monga gwero lounikira, kuyang'ana Angle ndi mawonekedwe ake, zingayambitse kusiyana pakuwunika kwamitundu.

01 Kusakanikirana kwamitundu

Ulalo wosindikiza wa toning ndiye zomwe zili pachimake pakusintha kwamitundu yonse. Nthawi zambiri, akatswiri ambiri osindikizira amabizinesi amangoyang'ana zomwe adakumana nazo kapena momwe amamvera pa toning, yomwe siili yovomerezeka kapena yogwirizana. Amangokhala mumtundu woyambirira wa toning ndipo amakhala wamba kwambiri. Kumbali imodzi, ilibe mphamvu pakusintha kwa chromatic aberration, kumbali ina, ndizovuta kusintha mtundu. Chachitatu, palibe luso loyenerera popanga luso lofananiza mitundu ya antchito.

Pamaso pa toning, chidwi chapadera chiyenera kuperekedwa poletsa kugwiritsa ntchito makina osindikizira a inki kuchokera kwa opanga osiyanasiyana kuchokera ku toning. Ndi bwino kugwiritsa ntchito inki yosindikizira kuchokera kwa wopanga yemweyo kwa toning. Ndikofunikira kuti ogwira ntchito a toning amvetse bwino tsankho lamitundu yosiyanasiyana ya inki yosindikizira, yomwe imathandizira kuwongolera pakupanga toning. Musanayambe toning, ngati inki yotsalira yosindikizira ikugwiritsidwa ntchito, m'pofunika kuti muyambe kumveketsa mtundu wa inki yosindikizira, fufuzani ngati chizindikiritso cha inki yosindikizira ndi yolondola, ndi bwino kugwiritsa ntchito chopukutira cha inki popukuta chitsanzo ndi kusindikiza. kuyerekezera, ndiyeno onjezerani, musanawonjezere, kulemera kuyenera kulimbikitsidwa kuti muyese, ndiyeno lembani deta.

Kuonjezera apo, pokonza mthunzi wa inki yapadera yamtundu, mungagwiritsenso ntchito njira yoyezera toning. Mukamakanda inki, iyenera kukhala yofanana, ndipo iyenera kukhala ndi maziko oyera, omwe amathandiza kufananitsa ndi chitsanzo chogwirizana. Pamene hue ifika kupitirira 90% ya chitsanzo chogwirizana, limbitsani kusinthika kwa viscosity. Titha kupanga zitsanzo, ndikuzikonza bwino. Ndikoyenera kutchula kuti popanga toning, chidwi chapadera chiyenera kuperekedwa ku kulondola kwa deta, ndipo kulondola kwazitsulo zamagetsi ndizofunikira kwambiri pofotokozera mwachidule magawo a deta. Pamene chiŵerengero cha deta kusindikiza inki amalimbikitsidwa, mwa kangapo mchitidwe akhoza mofulumira ndi zomveka toned, komanso angapewe kuchitika kwa mtundu kusiyana.

Ndi bwino kugwirizanitsa inki yofananira molingana ndi kukula kwa dongosolo, ndipo ndi bwino kumaliza ntchito yofananitsa utoto nthawi imodzi kuti mupewe kupatuka kwa chromatic komwe kumachitika chifukwa cha mitundu ingapo yofananira. Zingathe kuchepetsa kusiyana kwa mtundu ndi kupezeka kwa inki yotsalira yosindikiza. Mukayang'ana mtundu, nthawi zina ngakhale mtundu umawoneka wofanana m'munsimu zowunikira zonse, koma ziwoneka mosiyana koma pansi pa mtundu wina wa zowunikira, chifukwa izi ziyenera kusankha chowunikira chomwe chimagwiritsa ntchito mulingo wogwirizana chimapangitsa kuyang'ana mtundu kapena kufananiza mtundu.

02 Makina osindikizira

Chikoka cha kusindikiza scraper pa kusiyana kwa mtundu ngati scraper nthawi zambiri amasunthidwa pakupanga ndi kukonza, malo ogwirira ntchito a scraper adzasinthidwa, zomwe sizikugwirizana ndi kusamutsidwa kwanthawi zonse ndi kubalana kwa mtundu wa inki yosindikiza, ndi kukakamizidwa kwa scraper sichingasinthidwe mwachisawawa.

Musanayambe kupanga ndi kukonza, m'pofunika kusintha Angle ndi malo molingana ndi chithunzi ndi malemba a mpukutu wosindikiza. Mpeni wotsatira uyenera kupereka chidwi chapadera ku ntchito yoyera ndi yakuthwa ya dzanja. Angle of scraper nthawi zambiri amakhala pakati pa 50-60 madigiri. Kuonjezera apo, musanadulidwe, chisamaliro chapadera chiyenera kulipidwa kuti muwone ngati scraper mfundo zitatu ndizoyenera, ndipo sipadzakhala mtundu wa mafunde ndi malo apamwamba komanso otsika, omwe ndi ofunika kwambiri kuti pakhale kukhazikika kwa gawo losindikiza.

03 Kusintha kwa viscosity

Kusintha kwa viscosity kuyenera kulimbikitsidwa musanayambe kupanga ndi kukonza, ndipo ndi bwino kusintha malinga ndi liwiro la makina omwe akuyembekezeka. Pambuyo pa zosungunulira zawonjezedwa, makinawo amatsatana pambuyo pa mphindi 10 asanayambe kupanga ndi kukonza. Kuti ipititse patsogolo kupanga makina oyendera makina opangira makina kuti akwaniritse chidziwitso cha khalidwe, panthawiyi akhoza kuchita kudziwika kwa viscosity, monga momwe zimakhalira mtengo wamtengo wapatali wa mankhwalawa, mtengo uwu uyenera kulembedwa nthawi yomweyo ndi mankhwala onse amodzi malinga ndi deta. kusintha, akhoza kuchepetsa kupatuka kwa mtundu chifukwa cha kusintha kwa mamasukidwe akayendedwe. Kuzindikira mamasukidwe akayendedwe kuyenera kusamala kwambiri ndi luso lozindikira. Kawirikawiri, inki yosindikizira mu chidebe cha inki yosindikizira kapena beseni la inki yosindikizira ndilo gulu lalikulu lodziwira. Asanazindikire, ayi. 3 makapu akukhuthala ayenera kutsukidwa kuti atsogolere kuzindikira molondola.

Pakupanga kwabwinobwino, tikulimbikitsidwa kuti ma viscosity atsatire mphindi 20-30 zilizonse. Kapitawo kapena katswiri akhoza kusintha mamasukidwe akayendedwe malinga ndi kusintha kwa kukhuthala kwamtengo wapatali. Pamene kusintha mamasukidwe akayendedwe a inki kusindikiza ndi kuwonjezera zosungunulira, chidwi chapadera ayenera kuperekedwa osati mwachindunji amakhudza inki yosindikiza, pofuna kupewa kuwonongeka kwa dongosolo inki yosindikizira pansi zinthu yachibadwa, kulekana kwa utomoni ndi pigment, ndiyeno kusindikiza. tsitsi mankhwala, mtundu reproducibility sikokwanira.

04 Chilengedwe Chopanga

Malamulo a chinyezi cha mpweya wa msonkhano, nthawi zonse timasintha 55% -65% ndiyoyenera kwambiri.

Chinyezi chachikulu chidzakhudza kusungunuka kwa inki yosindikizira, makamaka kusamutsidwa kwa malo osaya kwambiri kumakhala kovuta kusonyeza bwino. Kusintha koyenera kwa chinyezi cha mpweya, kusindikiza kwa inki ndi kusintha kwa mtundu kumakhala ndi ntchito yabwino.

05 zopangira

Kaya kusamvana pamwamba pa zopangira ndi woyenerera kumakhudza kunyowetsa ndi kusamutsa zotsatira za inki yosindikizira pa gawo lapansi, komanso zimakhudzanso mawonekedwe amtundu wa inki yosindikizira pafilimuyo, komanso ndi chimodzi mwazinthu zomwe zimakhudza kusiyana kwa mtundu. . Kuonetsetsa ubwino wa zipangizo ndi chofunika kuti ulamuliro khalidwe. Ndikofunika kwambiri kusankha ogulitsa oyenerera.

06 Kudziwitsa Zapamwamba

Kudziwitsa zaubwino kumatanthawuza malingaliro amtundu wazinthu popanga, kukonza ndi kasamalidwe kabwino.

Lingaliro ili liyenera kukhala lodziwikiratu, likuwonekera mwatsatanetsatane wa ntchitoyo. Choncho mu kusintha mtundu kusiyana makamaka kutsogolera kuzindikira khalidwe la ndodo kusintha, mu ntchito yabwino, kuumba lingaliro la mankhwala khalidwe, monga proofing mosamalitsa kutsatira chitsanzo muyezo anafika oposa 90%, akhoza yambitsani kupanga ndi kukonza, mu gawo loyamba kuthandiza ogwira ntchito yowunikira kuti alimbikitse gawo loyamba la ntchito yoyendera.

Okhwima ndi ogwira ntchito kupanga ndi processing ntchito ya dongosolo kasamalidwe khalidwe, monga m'malo kusindikiza inki hue mu kupanga ndi processing, makamaka kulabadira kusindikiza inki beseni zambiri, ndi kupereka chidwi chapadera malekezero a pansi ndi kukanda. Chithunzi cha tsamba pali kusintha kwa nthawi kapena kuyeretsa, zing'onozing'ono izi, ngati sizipereka chidwi chapadera pakupanga ndi kukonza zimatha kuchitika pakati pa mtundu wosakanikirana, Chifukwa cha mtundu, ndiyeno chromatic aberration.

Kusiyanitsa kwamitundu kusindikiza sikungapeweke, momwe mungapewere kapena kuchepetsa zomwe zimachitika pakusiyana kwamtundu, ndiye chinsinsi, kusanthula mwatsatanetsatane zinthu zosiyanasiyana zomwe zili pamwambapa, kuti athe kupeza njira yabwinoko, zitha kupitilira kupewa kusiyana kwamitundu, njira kulamulira kusiyana mtundu, kokha pa gwero ndi chitsanzo kasamalidwe standardization, akhoza kuchepetsa ndi kupewa kusiyana mtundu, Pokhapokha ndi kupereka chidwi chapadera kwa kasamalidwe mwatsatanetsatane ntchito ndi ndondomeko deta mu kupanga ndi processing tingathe kupanga mankhwala bwino ndi kusintha mpikisano wathunthu wamsika wamabizinesi.
