Mukufuna kuwonetsa mtundu wa print pa skrini? Kusintha CMYK kukhala RGB kukupatsani chifanizo cha nyali cha makasitomala anu a inki — manambala omwe monita, mockup kapena tsamba la web lingawonetse.
Mmene kusintha kwa CMYK kukhala RGB kumagwirira ntchito
- Sinthani ma percent anayi kukhala ma fraction pakati pa 0 ndi 1.
- Gwiritsani ntchito key component koyamba: channel iliyonse imapangidwira ndi (1 − K).
- Werengani R = 255 × (1 − C) × (1 − K), G = 255 × (1 − M) × (1 − K) ndi B = 255 × (1 − Y) × (1 − K).
- Zizungulitseni channel iliyonse kukhala nambala yathunthu pakati pa 0 ndi 255.
Chitsanzo chomwe chagwira ntchito
Kukokomeza. Skrini imatha kuwonetsa mitundu yambiri kuposa yomwe inki imapanga, kotero zotsatira za RGB nthawi zambiri zimawoneka zowala komanso zodzaza kuposa zomwe zaperekedwa pazapeza.
CMYK and RGB explained
Kodi CMYK ndi chiyani?
CMYK ndi mawonekedwe a inki zinayi omwe amagwiritsidwa ntchito pa kusindikiza: cyan, magenta, yellow ndi key (black), iliyonse monga peresenti kuchokera ku 0 mpaka 100. Inki imatchula kuwala osati kumatulutsa, choncho CMYK imatha kufunsa mitundu yochepa kuposa skrini — chifukwa chake mitundu yowala ya skrini nthawi zina imawoneka yofooka ikasindikizidwa.
- Syntax:
- cmyk(C%, M%, Y%, K%)
- Range:
- 0–100% pa inki
- Best for:
- kusindikiza, zakatoni, ntchito zokonzekera kwa press
Kodi RGB ndi chiyani?
RGB imafotokozera mtundu monga njira zitatu za kuwala — red, green ndi blue — iliyonse kuchokera ku 0 mpaka 255. Izi zikufanana ndi momwe ma skrini amagwirira ntchito: zonse zitatu pa 255 zikupereka white, zonse pa 0 zikupereka black. RGB ndi yabwino pamene mukufunika kuwerenga manambala ndi mtundu, ndipo rgba() imawonjezera translucent.
- Syntax:
- rgb(R, G, B)
- Range:
- 0–255 pa channel
- Best for:
- code, canvas, kusintha kuwonekera ndi rgba()
