Malingana ngati mitundu itatu ya R+G+B igundana molingana, mitundu yopitilira mamiliyoni makumi ambiri imatha kupangidwa.Chifukwa chiyani wakuda?Black ikhoza kupangidwa pamene chiŵerengero cha RGB chiri chofanana, koma zimatengera inki zitatu kuti apange mtundu umodzi, womwe sungatheke pazachuma.Ndipotu, wakuda amagwiritsidwa ntchito kwambiri popanga mapangidwe, chifukwa chake kusindikiza kwa mitundu inayi kumagwiritsidwa ntchito.Palinso mfundo ina: pamene wakuda wopangidwa ndi RGB akufananizidwa ndi wakuda wophatikizidwa mwachindunji ndi inki, woyambayo amakhala ndi malingaliro opanda pake, pamene womalizayo amamva kulemera.

1. Ndi mfundo ya mitundu inayi, nkosavuta kuti aliyense avomereze.Ndilofanana ndi makanema anayi panthawi yotulutsa, komanso ikufanana ndi mayendedwe anayi a cyan, magenta, achikasu, ndi akuda (C, M, Y, K) mumayendedwe mu PHOTOSHOP.Kusintha kwa tchanelo tikamakonza chithunzicho ndikusintha kwa filimuyo.

2. Ukonde, madontho ndi ngodya, maukonde athyathyathya ndi maukonde olendewera.Mauna: pa mainchesi sikweya imodzi, kuchuluka kwa madontho omwe aikidwa, mauna 175 a zinthu zosindikizidwa wamba, ndi mauna 60 mpaka 100 a nyuzipepala, kutengera mtundu wa pepala.Kusindikiza kwapadera kumakhala ndi ma meshes apadera, kutengera kapangidwe kake.

1. Maonekedwe ndi kulondola kwa chithunzicho

Makina osindikizira amakono a offset amagwiritsa ntchito makina osindikizira a offset (a mitundu inayi mopitirira muyeso), ndiko kuti, chithunzi cha mtunducho chimagawidwa m’mitundu inayi: cyan (C), chopangidwa (M), chachikasu (Y), chakuda (B) filimu ya madontho amitundu inayi, kenako kusindikiza The PS plate imasindikizidwa kanayi ndi makina osindikizira, ndiyeno imakhala yosindikizidwa ndi mitundu.

Kusindikiza zithunzi ndizosiyana ndi zithunzi wamba zowonetsera pakompyuta.Zithunzizo ziyenera kukhala mumayendedwe a CMYK m'malo mwa RGB mode kapena mitundu ina.Mukatulutsa, chithunzicho chimasinthidwa kukhala madontho, omwe ndi olondola: dpi.Kufikira pang'onopang'ono kwazithunzi zosindikizira kuyenera kufika 300dpi/pixel/inchi, ndipo zithunzi zokongola zomwe mumakonda kuziwona pakompyuta nthawi zambiri zimamveka zokongola kwambiri pazowunikira.M'malo mwake, ambiri aiwo ndi zithunzi za 72dpi RGB, ndipo zambiri sizingagwiritsidwe ntchito kusindikiza.Zithunzi zomwe zimagwiritsidwa ntchito siziyenera kuwonetsedwa monga momwe zilili.Musaganize kuti zithunzizo zitha kugwiritsidwa ntchito kusindikiza chifukwa ndizabwino kwambiri kudzera mu acdsee kapena mapulogalamu ena, ndipo ndizabwino pambuyo pakukulitsa.Ayenera kutsegulidwa mu photoshop, ndipo kukula kwazithunzi kumagwiritsidwa ntchito kutsimikizira zowona.Kulondola.Mwachitsanzo: chithunzi chokhala ndi 600 * 600dpi / pixel / inchi, ndiye kukula kwake komweko kungathe kukulitsidwa kuwirikiza kawiri ndikugwiritsidwa ntchito popanda vuto lililonse.Ngati kusamvana ndi 300 * 300dpi, ndiye kuti kungachepetse kapena kukula koyambirira sikungakulitsidwe.Ngati kusintha kwa chithunzi ndi 72 * 72dpi / pixel / inchi, ndiye kukula kwake kuyenera kuchepetsedwa (kulondola kwa dpi kudzakhala kokulirapo), mpaka chisankhocho chitakhala 300 * 300dpi, chingagwiritsidwe ntchito.(Mukagwiritsa ntchito izi, ikani chinthucho "Redefine Pixel" munjira ya kukula kwa chithunzi mu Photoshop kuti zisachitike.)
Common image akamagwiritsa ndi: TIF, JPG, PCD, PSD, PCX, EPS, GIF, BMP, etc. Pamene drafting, TIF mtundu, bitmap wakuda ndi woyera, EPS vekitala kapena JPG

2. Mtundu wa chithunzi

Pankhani ya mawu ena akatswiri monga kusindikiza mochulukira, kusindikiza mochulukira, kutulutsa, ndi mtundu wamawanga posindikiza, mutha kutchulanso zina zoyambira zosindikiza.Nazi zina mwanzeru zomwe ziyenera kutsatiridwa.

1, kugwa

Pali mzere wa zilembo za buluu zomwe zapanikizidwa pa mbale yapansi yachikasu, kotero pa mbale yachikasu ya filimuyo, malo a zilembo za buluu ayenera kukhala opanda kanthu.Chosiyana ndi chowonadi cha mtundu wa buluu, apo ayi chinthu chabuluu chidzasindikizidwa mwachindunji pachikasu, mtunduwo udzasintha, ndipo chikhalidwe choyambirira cha buluu chidzakhala chobiriwira.

2. Kusindikiza

Pali mzere wa zilembo zakuda zopanikizidwa pa mbale ina yofiira, ndiye malo a zilembo zakuda pa mbale yofiira ya filimuyo sayenera kutsekedwa.Chifukwa chakuda chingathe kusunga mtundu uliwonse, ngati zakuda zakuda zatsekedwa, makamaka malemba ang'onoang'ono, kulakwitsa pang'ono posindikiza kumapangitsa kuti m'mphepete mwayera muwoneke, ndipo kusiyana kwakuda ndi koyera kumakhala kwakukulu, komwe kumakhala kosavuta kuwona.

3. Wakuda wamitundu inayi

Ilinso ndi vuto lofala kwambiri.Musanatulutse, muyenera kufufuza ngati mawu akuda mufayilo yosindikizira, makamaka zilembo zazing'ono, zili pa mbale yakuda yokha, ndipo zisawonekere pa mbale zina zamitundu itatu.Ngati ziwoneka, mtundu wazinthu zosindikizidwa udzachepetsedwa.Zithunzi za RGB zikasinthidwa kukhala zithunzi za CMYK, zolemba zakuda zimakhala zakuda zamitundu inayi.Pokhapokha ngati tafotokozedwa mwanjira ina, iyenera kukonzedwa filimuyo isanatulutsidwe.

4. Chithunzicho chiri mu RGB mode

Mukatulutsa zithunzi mumachitidwe a RGB, makina a RIP nthawi zambiri amawatembenuza kukhala CMYK mode kuti atulutse.Komabe, mtundu wamtundu udzachepetsedwa kwambiri, ndipo chosindikizidwa chidzakhala ndi mtundu wowala, osati wowala, ndipo zotsatira zake zimakhala zoipa kwambiri.Chithunzicho chimasinthidwa bwino kukhala CMYK mode mu Photoshop.Ngati ndi mpukutu wojambulidwa, uyenera kudutsa njira yokonza utoto chithunzicho chisanayambe kugwiritsidwa ntchito.
