He aha ka ʻokoʻa ma waena o RGB a me CMYK o ka mīkini paʻi Inkjet?

ʻO ke kumu hoʻohālike RGB e pili ana i nā kala kumu ʻekolu o ka mālamalama: ʻulaʻula, ʻōmaʻomaʻo, a me Blue, ʻo nā kukui kala ʻekolu me nā ʻāpana like ʻole o ka huina, hiki ke hana i nā ʻano kukui kala, ma ke kumumanaʻo, ʻulaʻula, ʻōmaʻomaʻo, hiki ke kukui uliuli. hui ʻia mai nā waihoʻoluʻu a pau.

Ma KCMY, pōkole ʻo CMY no ka melemele, keʻokeʻo, a me ka magenta. ʻO kēia nā kala waena o RGB (ʻekolu mau kala o ka māmā) i hui pū ʻia i ʻelua, ʻo ia ke kala hoʻohui o RGB

Ma mua o ka hele ʻana i nā kikoʻī, e nānā kākou i kēia:

Ma ke kiʻi, hiki iā mākou ke ʻike maopopo i ka hui ʻana o ka kala puaʻa CMY, ʻo ia ka ʻokoʻa koʻikoʻi, no ke aha ʻo KCMY kā mākou mīkini kiʻi a me ka mea paʻi UV? ʻO ka puaʻa, ʻo ka hui tricolor ʻaʻole pinepine ka ʻeleʻele maʻamau, akā he ʻulaʻula ʻeleʻele, no laila ʻeleʻele kūikawā ka inika K e neutralize.

ʻO ka ʻōlelo aʻoaʻo, ʻo RGB maoli ke kala i ke ʻano, ʻo ia ke kala o nā mea kūlohelohe āpau a mākou e ʻike ai me ko mākou mau maka.

I ka ʻoihana hou, ua hoʻohana ʻia nā waiwai waihoʻoluʻu RGB i ka pale a hoʻokaʻawale ʻia i nā kala kukui. ʻO kēia paha no ka mea ʻoi aku ka kiʻekiʻe o ka maʻemaʻe kala o ke kukui, no laila, ʻo ke kala e hōʻike maikaʻi loa i nā waiwai kala RGB. No laila hiki iā mākou ke hoʻokaʻawale i nā kala ʻike ʻia e like me nā waiwai kala RGB.

ʻO ka hoʻokaʻawale ʻana, ʻo ka KCMY ʻehā kala he ʻano kala i hoʻolaʻa ʻia no ka paʻi ʻana i ka ʻoihana a ʻaʻole ia he kukui.

E nānā kākou i ka hoʻohālikelike ma waena o ke ʻano kala kala RGB a me ke ʻano kala kala KCMY ma Photoshop:

(ʻO ka maʻamau, e hoʻohālikelike ka hoʻolālā kiʻi i ka ʻokoʻa ma waena o nā kala ʻelua no ka paʻi ʻana)


Hoʻonohonoho ʻo Photoshop i ʻelua mau ʻano kala RGB a me KCMY no ka hoʻokaʻawale ʻana. ʻOiaʻiʻo, ʻaʻole nui ka ʻokoʻa ma hope o ka paʻi ʻia ʻana, akā inā hana ke kiʻi ma RIP me ke kumu RGB, ʻike ʻoe i ka hopena o ka paʻi ʻana he ʻokoʻa nui e hoʻohālikelike ʻia me ke kiʻi kumu.
