CMYK ndi chiyani? Zinayi mtundu halftone (Cyan, Magenta, Yellow, Ofunika mtundu). CMYK ndi RGB

Ambiri amva CMYK chidule, ponena ntchito yofalitsa mabuku, koma sindikudziwa momwe iye waima. Kuti timvetsetse zimene mitundu anayi kuimira makalata amenewa ndi zimene katundu izo autotype kuthandiza nkhani yathu.

M'dziko Musanyengedwe kuwala

Pamaso ife tikupeza zimene CMYK, muyenera timvetsetsetse chikhalidwe cha chozizwitsa, ngati kuwala. anthu ochepa chabe amene amaganiza kuti mtundu alipo yekha mwa dongosolo, amene zigawo zikuluzikulu zofunika kwambiri pa kuonerera, kuunikira ndi zinthu. Zozizwitsa izi kuwala sikuthera pamenepo. Mwachitsanzo, ngakhale oyera kuwala woyera, timazindikira monga colorless, lili ndi mitundu yonse ya sipekitiramu zooneka ndi diso la munthu. Kamakupatsani iye multicomponent nkhani mtundu. Pamene kuwala woyera ukufika phunziro, pamwamba pake mosaganizira katundu, zimatenga mitundu yeniyeni. Pamene anatsala zimaonekera ndi kulenga mwa kum'patsa maganizo a fano kuti chinazilala kapena yowala.

Kubalana a mawu ndi zithunzi pa TV thupi ku mawonedwe nzeru anthu

Pepala lomwe yosindikiza zambiri poyamba woyera ndipo amatha akuimira sipekitiramu zonse za mitundu dzuwa, imene imagwera. The bwino quality, ndi apamwamba a padziko chinyezimiro katundu. Pa nthawi yomweyo, utoto - mankhwala kuti zimatenga mitundu ina. Ngati akuchedwa cheza mlengalenga ngati kuwala onse kupatula zokhazo zogwirizana ndi wofiira zikuluzikulu za sipekitiramu, ndi dzuwa munthu amaonera yekha utoto. Ngati tiyang'ana pa pigment chomwecho mu chowala la nyali buluu, izo tikuona wakuda.

Pamene pepala woyera chagwiritsidwa mitundu yosiyanasiyana, kuchepetsa kuchuluka kwa mitundu akusonyeza. Mwachitsanzo, potsatira buluu pigment pepala, ife kupanga zinthu kumene osati zimatenga izo.

Pali osakaniza mitundu, pamene osokonezeka sipangakhalenso analandira utoto, luso kwathunthu kuyamwa cheza zonse zimaonekera ndi pepala, ndicho. E. Kuti likhale lakuda. Makamaka, ndi wokwanira ntchito yofanana magenta, cyan ndi inki chikasu.

Tikumbukenso kuti chitsanzo mtundu sayenera utoto woyera, monga mtundu uwu wa pepala yokha. M'madera a fano kumene chofunika, palibe inki Kungoti sizinaikidwe, kusiya pamwamba woyera.

subtractive lachitsanzo

Paper ndi nkhani ina kusindikizidwa - ndi nyemba kuti tikhoza kuonetsa zachilengedwe kapena yokumba kuwala. Ndithudi, yabwino kuwerengera, kuchuluka kwa izo mu maonekedwe a kunyezimira anasintha malangizo ake kwa zosiyana kuposa momwe kuyamwa. Choncho, ngati subtracted ku mitundu 3 yaikulu woyera, zigawo E. Basic RGB mwachitsanzo., Izo patatu wowonjezera mitundu CMY.

Chifukwa «K», m'malo «B»

Kawirikawiri anthu amene sakudziwa chimene CMYK, chidule izi zosokoneza. Ndipotu, monga zanenedwa, ichi chitsanzo cha mtundu amagwiritsa 4 inki osiyana. Atatu a iwo otchedwa ndi kalata yawo yoyamba. Komanso, wakuda ntchito. Baibulo lina limanena kuti K - ndi chidule cha mawu English wakuda. Icho chinali kugwiritsidwa ntchito m'malo mwa "pa" kutanthauza wakuda filimu pa ntchito yofalitsa mabuku, osati kusokonezedwa ndi chimodzimodzi ndi kalata ya RGB chitsanzo (Eng. Blue). chakuti akatswiri mtundu correctors amayendela RGB_CMYK_Lab 10 TV ndipo ntchito mipata yonse zilipo mtundu. Choncho, pamene ntchito chidule kwa zinayi autotype, mawu akuti "kanthu ndi njira B» kungafune powunikira pa aliyense wa zitsanzo funso, kungakhale kovuta.

Pali view wina. Malinga ndi buku ili, «K» - ndi chidule cha mawu akuti "mfungulo" ie mbale kiyi ... Iwo amanena kuti mabuku mtundu wa inki yakuda kuti umagwiritsidwa pamwamba pa kale waikamo atatu pigment m'mbuyomu.

Komanso, akatswiri ena okonda amakhulupirira kuti "K" ndi katchulidwe German ndipo tanthauzo la mawu kontur. Mokomera Baibulo atsopano n'chakuti mwambo wakuda filimu ntchito yosindikiza otchedwa contouring.

Kodi kutchula mu Russian

Ngakhale CMYK chitsanzo mtundu lakhala likugwiritsidwa ntchito kwa nthawi yaitali, anthu ambiri sakudziwa lero momwe kuwomba chidule izi. Akatswiri kunena mokweza, monga "C-EM-Wye Kay." Komanso, pali malangizo kutchedwa 4-mtundu avotipiyu "B-Mac", komanso kugwiritsa ntchito mawu akuti "makaka" kapena "ndondomeko inks".

RGB, CMYK: kodi pali kusiyana

Ngati CMYK chiwembu ntchito mu ntchito yosindikiza, ndi red-wobiriwira buluu chitsanzo ntchito anasonyeza pa ma TV, oyang'anira kusonyezedwa ena. Monga tikudziwa? iwo zigwirizana pixels amene ali madontho ang'onoang'ono, omwe ali backlight 3, malingana ndi kuwala kwa aliyense zounikira mthunzi Napempha kwa mtundu.

Pamene fano imasindikizidwa ku kompyuta, chosindikizira kapena kuchepetsa atolankhani kuchita pogwiritsa ntchito mitundu CMYK (cyan, magenta, wachikasu, mtundu kiyi). Choncho, kuonera chifaniziro RGB chiwembu zingasiyane kwambiri ndi zimene inu mufika pa pepala kapena zina chogwirika chinthu.

Chifukwa njira fano kusintha kwa mtundu wina kudera lina lomwe sitingapeze kupereka kwathunthu kugunda. Inde, ambiri RGB mitundu chabe kulibe ndipo sangathe akuyendera ndi phale CMYK (kiyi iliyonse mtundu dongosolo, mukudziwa kale). Iwo m'malo ndi hue wapamtima koma kusiyana alipobe mpaka ndithu ngakhale kuti apoyera.

Chifukwa mu CMYK 4 mitundu, ndi RGB ali okha 3

Monga mukudziwa, inki yakuda akhoza kukhala okonzeka ndi kusakaniza magenta, wachikasu, ndi buluu, kutengedwa mulingo ofanana. Komabe, ena zifukwa tili ntchito pigment zina. Chifukwa zinayi autotype zimaphatikizapo kugwiritsa ntchito wakuda utoto, ochepa. Pakati pawo:

• chisakanizo cha chikasu, magenta ndi cyan inki, mu kuchita, kulenga zauve bulauni mtundu ;
• ndondomeko inks Musapereke mtendere wa hue machulukitsidwe ndi malo imvi wa fano;
• pamene outputting oche- mbali yakuda ya lemba kapena mfundo popanda kugwiritsa ntchito pigment ngati kumaonjezera ngozi ya mwangozi insufficiently enieni mfundo za ntchito cyan, magenta ndi mitundu chikasu;
• pigment wakuda (amangoona ochiritsira mpweya wakuda) ndi mtengo kwambiri kuposa utoto ena;
• kusanganikirana 100% chikasu, magenta kapena cyan pigment pa mfundo imodzi mu nkhani ya inkjet mokwanira kwambiri wets pepala, izo deforms ndi kuonjezera nthawi wofunikila kuyanika.

mtundu yotsirizira ya mavuto mu ndondomeko ya makina osindikizira. Komanso, malingana ndi chipangizo? Pali zina zofunikila pa kuchuluka kwa utoto. Mu ena osindikiza mabuku, izo kungakhale ndithu lalikulu ndi kufikira 260-280%. Izi zikutanthauza kuti "lenileni" lakuda makina onga yosindikiza anawakonzera kusakaniza inki zosatheka. Choncho, ntchito utoto wina wakuda.

ndi CMYK zilembo Kodi

Pamene yosindikiza kapena silika mafilimu kusindikiza pa kusindikiza makina kuchepetsa, osindikizira mtundu laser, ndi zina zotero. E. N'zotheka pa mfundo iliyonse, kapena ntchito yeniyeni inki wosanjikiza makulidwe, kapena kusiya gawo lapansi liziyenda ndi woyera. Choncho, kupatsira rasterized halftone fano. Mu mawu ena, ankayimiridwa ngati ya madontho a mitundu inayi. osalimba a Kusinthaku awo Mzimuyo kuchuluka kwa ntchito ya aliyense wa mitundu. Patali ndi sing'anga thupi (pepala, film, etc.) The mfundo pafupi wina ndi mnzake, kuphatikiza, ndi maso athu amaona hue ankafuna. RIP ndi:

• matalikidwe pamene chiwerengero cha mfundo ndi zonse, koma zimasiyanasiyana kukula awo;
• zosapanganika pamene palibe zonse mfundo dongosolo;
• pafupipafupi, kutanthauza kukula kusamala pamene kusintha kuchuluka kwa mfundo.

Kodi si tidzakhumudwa pamene inu kusindikiza zithunzi pa chosindikizira

Lero, osindikiza ali mu nyumba zambiri. Iwo ntchito yokonza homuweki, kulemba mapepala akuti, essays, ndi zina zotero. Nthawi zambiri, chosindikizira kuyesetsa kusindikiza zithunzi. Komabe, zoyesayesa amangoona ngati mathero kukhumudwa chifukwa yowala chithunzi pa TV amakhala chinazilala bukulo pa pepala. nkhani zonse ntchito yomasulira fano kwa RGB kuti CMYK chitsanzo chitsanzo.

Kuona mmene chithunzi lidzaonekera pa pepala, mukhoza kugwiritsa ntchito pulogalamu Adobe Photoshop. Pankhaniyi, fano akhoza losasinthika pofuna kupeza zotsatira zabwino.

Tsopano inu mukudziwa chomwe CMYK, ndi acronym anaima ndi zimene zolakwa iwo ali. Ambiri mwina, posachedwapa ku malo ake akubwera patsogolo kwambiri mtundu chiwembu kuti adzasintha khalidwe la fano yosindikiza.
