Ukeneye kugaragaza ibara ryo gucapisha kuri ecran? Guhindura CMYK muri RGB biguha ingero zishingiye ku rumuri z'izo percentages z'ink — ni byo monitor, mockup cyangwa urubuga bishobora kwerekana.
Uko guhindura CMYK ujya RGB bikora
- Fata ijanisha enye nk'ingano ya wino ku mwirondoro wa Coated FOGRA39.
- Soma ibara umwirondoro ucapa kuri uwo muvange wa wino, ukoresheje uburyo bugereranya amabara hamwe no guhindura ingingo y'umukara.
- Hindura iryo bara muri sRGB. Amabara ecran idashobora kwerekana acibwa akagera ku ibara rya hafi ryerekanwa.
- Hinnya buri channel kugira ngo ibe imibare yuzuye hagati ya 0 na 255.
Urugero rwakozwe
Igisubizo cya RGB kigaragaza uko uwo muvange wa wino usa ku mpapuro zisize, ukoresheje umwirondoro usanzwe wa Coated FOGRA39. Indi mirondoro ya CMYK (urugero iyo mu ruganda rw'icapiro rwawe) itanga imibare itandukanye, kandi icapiro ntirigaragara nka ecran.
CMYK na RGB bisobanuwe
Icyo CMYK ari cyo
CMYK ni modelu y'inkuru enye ikoreshwa mu icapiro: cyan, magenta, yellow na key (umukara), buri rimwe rigaragara nka percentage kuva 0 kugeza 100. Ikoresha inyandiko ikuraho urumuri aho kururekura, bityo CMYK ifata amabara make kurusha ecran — ari yo mpamvu amabara asobanutse ku ecran akenshi asa n'atarimo ubwo acapwe.
- Imiterere:
- cmyk(C%, M%, Y%, K%)
- Urutonde:
- 0–100% kuri buri ink
- Byiza kuri:
- icapiro, ipaki, ibikorwa biteguye gucapwa
Icyo RGB ari cyo
RGB isobanura ibara nka channel eshatu z'urumuri — umutuku, icyatsi na bleu — buri kimwe kuva 0 kugeza 255. Ihuza n'ukuntu ecran zikora: byose kuri 255 bitanga umweru, byose kuri 0 bitanga umukara. RGB ni cyo cyiza igihe ugomba gukora imibare ku ibara, kandi rgba() yongeza transparency hejuru.
- Imiterere:
- rgb(R, G, B)
- Urutonde:
- 0–255 kuri buri muyoboro
- Byiza kuri:
- code, canvas, transparency na rgba()
