Ungawutshintsha njani ngokufanelekileyo umbala kwi-GIMP (kunye ne-2)
Nje ukuba siqonde ukuba izixhobo zedijithali kunye nabahloli babamba kwaye bavelise umbala, siyaqhubeka.
II.- Kutheni ulungelelanisa umbala kwi-RGB?
GIMP, Ngokungafaniyo Photoshop, ayinayo indlela yakudala yokuphatha umbala ngendlela Ukuthabatha Umbala -ikwabizwa CMYK- kodwa yenza njengoko RGB. Uninzi lwabayili bemizobo benza impazamo yokwenza uhlengahlengiso lwemibala yabo besebenzisa inkqubo CMYK eyimpazamo enkulu, ukuze uqonde ukuba kutheni ndithetha into enjalo, makhe sibone, ngokufutshane, ukuba yintoni na...
Inkqubo yoMbala eThathayo okanye i-CMYK: kwisitolimende sokugqibela besichazile ukuba zimbini iindlela "okwenziwayo" ukuvelisa umbala; yena Inkqubo eyongezelelweyo -esele sibonile- kwaye i Inkqubo yokuthabatha, eyaziwa ngcono njenge CMYK.
El Inkqubo yoMbala eThathayo, Ngokungafaniyo RGB ivela kubumnyama obupheleleyo -imonitha ecinyiweyo ayibonisi mibala kwiscreen- isuka kumbala, odla ngokuba mhlophe, we substrate -iphepha, ilaphu, okanye nawuphi na umgangatho oprintwayo– apho kongezwa ii-pigments. Kubizwa ngokuba yi-subtractive kuba imibala esiyibonayo iyisiphumo sokuthatyathwa kwamaza okukhanya kumphezulu we-pigmented substrate okanye ipeyintiwe.
Inkqubo yombala RGB
Iqala ngobumnyama...
…Ngeli xesha yena CMYK se
iqala phezu komhlaba,
ngokuqhelekileyo mhlophe.
Ngokuqhelekileyo le ndlela isetyenziselwa ushicilelo lwamashishini -iincwadi, iipowusta, iiflaya, iimagazini, iilebhile, njl..- kwaye ukufezekisa oku, ii-inks ezintathu okanye imibala iyasetyenziswa: Cyan, Miarhente, Yellow kunye noblacK, kungoko isifinyezo CMYK.
Ukufezekisa ii-nuances ezahlukeneyo, imifanekiso iqanduselwa ibe ngamachaphaza amancinci anobukhulu obahlukeneyo (jonga umfanekiso) obizwa ngokuba zii-inki ezininzi.
"OK Umgqomo, Oko sele kuqondwa ... kodwa ke kutheni isihogo kufuneka ndihlengahlengise umbala RGB kwaye akunjalo CMYK?”abafundi bam ababini abaqhelekileyo abaqondayo baya kubuza. Kukho izizathu ezibini:
- Nangona kunjalo CMYK Ngokuqinisekileyo yindlela yokumela umbala ukuba siguqula amaxabiso ngaphakathi kwesi sixokelelwano. Enyanisweni into esiyitshintshayo ngamaxabiso e-inki eninzi, eyimpazamo. Ukuba nabani na unemibuzo malunga noku, ndingakuvuyela ukukuchazela.
- Uluhlu oluguquguqukayo lombala wenkqubo CMYK Limxinwa kakhulu kunolo lwe RGB, ke ukuba senza uguqulo lwe RGB a CMYK Kuya kubakho ilahleko enkulu yolwazi lombala olungenakufunyanwa nangayiphi na indlela. (Jonga imifanekiso)

Ukuqhubeka ...
Argggg!!! Xa ndibhideka ngakumbi, uyandinqanda ekufundeni. Ifana kakhulu neekhathuni zaseRashiya: Koniec !!! Hahaha..
Enkosi ngesi sigaba sesibini ndifuna ukwazi ngakumbi *-*
Umbuzo, ingxaki yokulahleka kolwazi lombala woshicilelo lwemizi-mveliso isonjululwe njani? okanye usebenza kwasekuqaleni kwi CMYK? Andingomyili nangayiphi na indlela kodwa ndinomdla wokwazi.
I-PS: Ngendlela, inqaku elihle kakhulu! , ndilinde inxalenye elandelayo.
Hayi, akufuneki uqhubekisele phambili umfanekiso CMYK kodwa kwi RGB, nangakumbi ukuba umfanekiso ukwimowudi CMYK kufuneka uyiguqulele kuyo RGB ukulungisa umbala.
Adobe Photoshop inomsebenzi wokujonga kwangaphambili CMYK yomfanekiso kwi RGB, le preview "ilinganisiwe" kusetyenziswa iinkangeleko ICC ukufumana kwimonitha umfanekiso ofanayo kakhulu nento eza kushicilelwa. Oku kubizwa ngokuba "luVavanyo oluthambileyo."
Ngoku, ukuba into esiyifunayo ngumfanekiso osondeleyo kuluhlu lombala RGB Okona kucetyiswayo lushicilelo lwe-Hi-Fi, olukwabizwa ngokuba yi-hexacrom. ( http://consultoresfca.blogspot.com/2008/07/hexacromia-impresion-seis-colores.html )
Ukuba nabani na ufuna ukuphengulula nzulu kulawulo lombala kubugcisa begraphic, ndicebisa le ncwadana enkulu: http://gusgsm.com/notas_administracion_o_gestion_color
Ndilinde inxalenye yesithathu.
Nangona ndiyazibuza, kuncinci ngaphandle kwesihloko, ngaba kukho i-RGB kunye ne-CMYK kuphela okanye kukho abanye?
Hola Arturo:
Hayi, azikho ezinye… imodeli yombala R KUNYE B -Ebomvu, etyheli, eBlue = ebomvu, etyheli, eluhlaza okwesibhakabhaka-, nto leyo esiyifundayo xa sidlala ngeekhrayoni kwi-kindergarten, yinkqubo esele iphelelwe lixesha.
Imibala emitsha ye-HiFi esetyenziswa kushishino lobugcisa bemizobo eneneni yahlukile yenkqubo ye-CMYK kuba ilandela umgaqo wayo ofanayo: ukusebenzisa uthotho lwe-inki eninzi kwi-substrate ukuphumeza uluhlu lwemibala.
Kukho iindlela ezininzi zokubonisa amaxabiso ombala, enye yazo yile isetyenziselwa uyilo lwephepha lewebhu: inkqubo yehexadecimal.
Kwisahluko III ndiya kuchukumisa kwesi sihloko kancinci.
Yayimfutshane kangakanani, uxolo ngenxa yokuxhatshazwa, uya kuqonda.
Ukungena kwam kwihlabathi le-Ph, ndajonga kuphela kwi-tutorial emva kwe-tutorial de ndibe neendlela ezishiyekileyo, iindlela ezimfutshane ze-keyboard kunye nezinye izinto, ayizange ithi qatha kum ukuba ndiqale apho uchaza khona izinto, yiyo loo nto ndizive ndimncinci xa ndifunda. ingxelo yakho "Gimp apho ewe kwaye phi ngamanye amaxesha" (okanye into enjalo) Andizange ndicinge ezo meko.
Enkosi Tina
Jonga indlela enika umdla ngayo, ukusukela oko sasingabantwana sidlala ngemibala kwaye singaqondanga sisebenzisa iimodeli ezinje R KUNYE B ukufunda imvano-siphelo ethandwa kakhulu
♪ Ebomvu, etyheli kunye neBlue… ikhathalogi! ♪

Molo, ndinombuzo ... Ndisebenzisa i-Gimp 2.8 kwaye ndaguqulela kwi-RGB ukuya kwi-CMYK nge-Separate + kwaye kwaphuma into emnyama. Ndingayicacisa njani?
Ndicinga ukuba ineMagenta eninzi kakhulu.
Molo, isifundo esihle! Bendijonge into eyahlukileyo kuba ndifunda ngokuthozama ukuzoba eKrita. Ndichukumise into kwaye ngoku ndiyabona ukuba imibala icinyiwe. Ngokunjalo, xa ndiguqula umfanekiso kwiJPG yonke into ibuyela kwesiqhelo, kodwa yintlungu. Ndiyilungiselele kwi-RGB kodwa akukho nto, ndisayibona imibala efana nefilimu endala ... kuya kufuneka ndiyifake kwakhona? Enkosi ngegalelo, lindincede ukuba ndiqonde into engaphezulu malunga nayo yonke le nto.
