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. Pamaso toning, ngati otsala inki yosindikizira ntchito, m`pofunika choyamba kufotokoza momveka bwino mtundu wa inki yosindikiza, fufuzani ngati chizindikiritso khadi la inki yosindikiza ndi lolondola, ndi bwino ntchito inki scraper kwa kukanda kuonerera chitsanzo ndi kuyerekezera, ndiyeno kuwonjezera, pamaso kuwonjezera, kulemera ayenera kulimbikitsidwa kuti alembe deta, ndiyeno.

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 kwachibadwa ndi kutulutsa mtundu wa inki yosindikiza, ndipo kupanikizika kwa scraper sikungasinthidwe mosasamala.

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 processing kuyendera makina mankhwala kukumana muyezo wa kuzindikira khalidwe, pa nthawi ino akhoza kuchita mamasukidwe akayendedwe kudziwika, monga ogwirizana muyezo mamasukidwe akayendedwe mtengo wa mankhwala, mtengo ayenera kulembedwa yomweyo ndi lonse mankhwala limodzi malinga ndi deta kusintha, akhoza zomveka kuchepetsa kupatuka mtundu chifukwa cha kusintha mamasukidwe akayendedwe. Kuzindikira mamasukidwe akayendedwe kuyenera kusamala kwambiri 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 kuti osati mwachindunji zimakhudza inki yosindikiza, pofuna kupewa kuwonongeka kwa dongosolo inki yosindikizira pansi zinthu yachibadwa, kulekana kwa utomoni ndi pigment, ndiyeno kusindikiza mankhwala tsitsi, 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 zofunika 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 kwa mtundu kusiyana makamaka kutsogolera kuzindikira khalidwe la ndodo kusintha, mu ntchito yabwino, kuumba lingaliro la khalidwe mankhwala, monga proofing mosamalitsa kutsatira chitsanzo muyezo anafika oposa 90%, akhoza kuyamba kupanga ndi processing, mu chidutswa choyamba kuthandiza ogwira ntchito yoyendera khalidwe kulimbitsa gawo loyamba la ntchito yoyendera.

Okhwima ndi ogwira ntchito kupanga ndi processing ntchito ya dongosolo khalidwe kasamalidwe, monga m'malo kusindikiza inki hue mu kupanga ndi processing, makamaka kulabadira kusindikiza inki beseni mfundo, ndi kulabadira mwapadera malekezero a pansi ndi kuti kukanda tsamba kopanira pali kusintha kwa nthawi kapena kuyeretsa, mfundo zazing'ono izi, ngati sapereka chidwi chapadera pa kupanga ndi kukonza, Cause ndi mtundu wosanganiza huloration akhoza kuchitika pakati pa mtundu wosakanikirana wa disc.

Kusiyana kwamitundu kusindikiza sikungalephereke, momwe mungapewere kapena kuchepetsa zomwe zikuchitika za kusiyana kwa mtundu, ndiye chinsinsi, kusanthula mwatsatanetsatane zinthu zosiyanasiyana zomwe zili pamwambapa, kuti athe kupeza njira yabwino, atha kupeweratu kusiyana kwamtundu, njira yothanirana ndi kusiyana kwa mtundu, kokha pa gwero ndi kasamalidwe kachitsanzo, kungachepetse ndi kupewa kusiyana kwamtundu, Pokhapokha popereka chidwi chapadera ku kasamalidwe kazinthu zopanga bwino komanso kukonza bwino msika titha kupanga bwino ntchito yopanga ndi kukonza deta. mpikisano wamakampani.
