He aha ka ʻokoʻa o RGB a me CMYK i ka hihia o kahi paʻi Inkjet

He aha ka ʻokoʻa o RGB a me CMYK i ka hihia o kahimīkini paʻi inkjet?

ʻO ke kumu hoʻohālike RGB nā kala kumu ʻekolu o ka māmā. ʻulaʻula, ʻōmaʻomaʻo, a me ka uliuli. ʻO kēia mau kala kumu ʻekolu, loaʻa nā ʻāpana like ʻole i hiki ke hana i nā kala like ʻole. Ma ke kumumanaʻo, hiki ke hoʻohui ʻia ke kukui ʻōmaʻomaʻo, ʻulaʻula a me ka uliuli me nā aka ʻē aʻe.

ʻIke ʻia ʻo ia ʻo KCMY, pōkole ʻo CMY no ka melemele, cyan a me ka magenta. ʻO kēia nā kala i hoʻohui ʻia i nā waena waena o RGB (ʻekolu mau aniani o ka mālamalama) i hui pū ʻia i nā pālua ʻo ia ke kala hoʻohui o RGB

Ma mua o ko mākou komo ʻana i nā kikoʻī, e noʻonoʻo kākou i kēia:

Ma ke kiʻi, ua maopopo ka waihoʻoluʻu CMY ka hui ʻana. ʻO kēia ka ʻokoʻa nui, no ke aha ka mea paʻi kiʻi a me ka paʻi UV ʻo KCMY? ʻO kēia ma muli o ka hiki ʻole i ka ʻenehana i hoʻohana ʻia i kēia manawa ke hana i nā puaʻa maʻemaʻe kiʻekiʻe. Hiki ke ʻokoʻa ka hui tricolor mai ka ʻeleʻele maʻamau, akā he ʻulaʻula ʻeleʻele ia, kahi e koi ai i kahi ʻīnika ʻeleʻele kūikawā e hiki ke neutralize.

ʻO ke kumu, ʻo RGB ke kala maoli, ʻo ia ke kala i loaʻa i nā mea kūlohelohe āpau a mākou e ʻike ai.

I kēia manawa, hōʻike ʻia nā waiwai kala RGB ma nā pale i hoʻokaʻawale ʻia e nā kala ʻālohilohi. ʻO kēia ma muli o ka maʻemaʻe o ka mālamalama ʻoi aku ka maikaʻi, a no laila ʻo ke kala i pololei loa e hōʻike ana i nā waiwai hue RGB. No laila hiki iā mākou ke hoʻokaʻawale i nā kala ʻike ʻia e like me nā kala RGB.

Kū'ē i kēlā, hōʻike nā kala KCMY 4 i nā kala kala i manaʻo ʻia no ka paʻi ʻoihana. ʻAʻole lākou i ʻālohilohi. ʻOiai ka lōʻihi o ka paʻi ʻana o ke kala kala ma nā ʻano media like ʻole me ka hoʻohana ʻana i nā mea hana hou no ka paʻi ʻana Hiki ke hoʻokaʻawale ʻia ke ʻano kala ma lalo o ke ʻano KCMY.

E nānā kāua i ka ʻokoʻa o ke ʻano kala kala RGB, a me KCMY nā ʻano kala i Photoshop:

(ʻo ka mea maʻamau e hoʻohālikelike ka hoʻolālā kiʻi i nā ʻokoʻa ma waena o nā kala ʻelua o ke kumu o 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.

Inā makemake ʻoe e aʻo hou, e ʻoluʻolukāhea iā mā˚ou.
