Pono e hōʻike i ke kala paʻi ma ka pale? Hōʻike ka hoʻololi mai CMYK i RGB i ka hoʻohālikelike kukui o kāu mau pākēneka inc — nā waiwai a hiki i ka monitor, mockup a i ʻole ka paʻi pūnaewele ke hōʻike.
Pehea e hana ai ka kahuli mai CMYK i RGB
- E hoʻololi i nā pākēneka ʻehā a pau i mau ʻāpana ma waena o 0 a 1.
- E hoʻopili i ka key component ma mua: hoʻopaʻa ʻia kēlā me kēia kanal e (1 − K).
- E helu i R = 255 × (1 − C) × (1 − K), G = 255 × (1 − M) × (1 − K) a B = 255 × (1 − Y) × (1 − K).
- E puʻupuʻu i kēlā me kēia kanal i helu holoʻokoʻa ma waena o 0 a 255.
Laʻana i hana
He approximation. Hiki i ka pale ke hōʻike i nā waihoʻoluʻu he nui aʻe ma mua o ka inc, no laila ʻo ka hopena RGB maʻamau e hiʻohiʻona ʻoi aku ka ʻālohilohi a ʻoi aku ka saturated ma mua o ka paʻi ʻia.
CMYK a me RGB wehewehe
He aha ka CMYK?
ʻO CMYK ka hiʻohiʻona ʻehā-ink i hoʻohana ʻia i ka paʻi: cyan, magenta, melemele a me ke key (ʻeleʻele), kēlā me kēia ma kahi pākēneka mai 0 a 100. Hoʻemi ka ʻinki i ka mālamalama ma ke ala o ka hoʻopau ʻana, ʻaʻole e hoʻokuʻu mai, no laila ʻoi aku ka liʻiliʻi o nā waihoʻoluʻu a hiki i CMYK ma mua o ka pale — no laila hiki i nā waihoʻoluʻu ʻālohilohi o ka pale ke ʻike i ka maʻū ma ka paʻi ʻana.
- Hana kikokiko:
- cmyk(C%, M%, Y%, K%)
- Awāwa:
- 0–100% per ink
- Mākou kūpono no:
- paʻi, hoʻopaʻa pūʻolo, artwork mākaukau no ka press
He aha ka RGB?
Hōʻike ka RGB i kahi waihoʻoluʻu ma mau kanaloku ʻekolu o ke kukui — ʻulaʻula, ʻōmaʻomaʻo a me ke kanaloku polū — kēlā me kēia mai 0 a 255. Hoʻohuli ia i ka hana o nā pale maoli: inā pau nā ʻekolu i 255, makaʻele ke keʻokeʻo; inā pau i 0, makaʻele ka ʻeleʻele. He kūpono ka RGB inā pono ʻoe e hoʻoluku me kahi waihoʻoluʻu, a hoʻohui ʻia ka rgba() no ka ʻolepili.
- Hana kikokiko:
- rgb(R, G, B)
- Awāwa:
- 0–255 per channel
- Mākou kūpono no:
- code, canvas, koʻikoʻi me rgba()
