RGB ndi yonse ya kuwonjezera ndipo imapangidwa ndi nyali, CMYK ndi yochotsa ndipo imapangidwa ndi inki. Kusintha pakati pawo ndi sitepe yomwe kapangidwe ka skrini konse kamatenga asanapereke.
Mmene kusintha kwa RGB kukhala CMYK kumagwirira ntchito
- Werengani R, G ndi B ngati mitengo ya sRGB pakati pa 0 ndi 255.
- Fufuzani mtunduwo mu mbiri ya Coated FOGRA39, mbiri yokhazikika ya ICC ya pepala lopaka ku Ulaya.
- Gwiritsani ntchito njira yoyezera mitundu yofananira pamodzi ndi kuwongolera mfundo yakuda, kuti mtundu woyera ukhalebe woyera wa pepala ndipo wakuda ukhale inki yakuda kwambiri yomwe makina osindikizira angasindikize.
- Sinthani ma value onse anayi kukhala ma percent pakati pa 0 ndi 100.
Chitsanzo chomwe chagwira ntchito
Izi zimagwiritsa ntchito mbiri yokhazikika ya Coated FOGRA39. Malo osindikizira amagwira ntchito ndi mbiri zawo za ICC ndi malire a inki, choncho mbiri zina za CMYK (mwachitsanzo kuchokera kumalo anu osindikizira) zimapereka manambala osiyana. Onani zotsatirazi ngati maziko odalirika, osati kugawa kwa mitundu kokonzeka kusindikizidwa.
RGB and CMYK explained
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()
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
RGB to CMYK reference table
Mitundu yophweka kwambiri ya CSS, yasinthidwa kuchokera ku RGB kupita ku CMYK.
