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

He aha ka ʻokoʻa ma waena o RGB a me CMYK i ka hihia o kahimīkini paʻi ʻīnika?

ʻO ke kumu hoʻohālike kala RGB nā kala mua ʻekolu o ke kukui. ʻUlaʻula, ʻŌmaʻomaʻo, a me Polū. ʻO kēia mau kala mua ʻekolu, nona nā ʻāpana like ʻole e hiki ai ke hana i nā ʻano kala like ʻole. Ma ke kumumanaʻo, hiki ke hui pū ʻia ke kukui ʻōmaʻomaʻo, ʻulaʻula a me ka polū me nā aka ʻē aʻe.

Ua kapa ʻia hoʻi ʻo KCMY, ʻo CMY ka pōkole no ka melemele, cyan a me ka magenta. ʻO kēia nā kala e hana ana i nā waena ma RGB (ʻekolu mau aka mua o ke kukui) i hui pū ʻia ma nā hui ʻo ia ke kala hoʻohui o RGB.

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

Ma ke kiʻi, ua maopopo he hui ʻana o ke kala CMY. ʻO kēia ka ʻokoʻa nui, no laila no ke aha i kapa ʻia ai kā mākou mīkini paʻi kiʻi a me ka mīkini paʻi UV ʻo KCMY? ʻO kēia ma muli o ka ʻoiaʻiʻo ʻaʻole hiki i ka ʻenehana e hoʻohana nei i kēia manawa ke hana i nā pigments maʻemaʻe kiʻekiʻe. Hiki ke ʻokoʻa iki ka hui ʻana o nā kala ʻekolu mai ka ʻeleʻele maʻamau, akā he ʻulaʻula ʻeleʻele ia, e pono ai kahi ʻīnika ʻeleʻele kūikawā e hiki ke hoʻopau.

Ma ke kumumanaʻo, ʻo RGB ke kala kūlohelohe, ʻo ia ke kala i loaʻa i nā mea kūlohelohe a pau a mākou e ʻike ai.

I kēia au hou, hōʻike ʻia nā waiwai kala RGB ma nā pale i hoʻokaʻawale ʻia e nā kala ʻālohilohi. ʻO kēia ma muli o ka maʻemaʻe o ke kukui ka mea maikaʻi loa, a no laila ke hōʻike pololei loa ke kala i nā waiwai hue RGB. No laila hiki iā mākou ke hoʻokaʻawale i nā kala i ʻike ʻia he mau kala RGB.

ʻAʻole like me kēlā, hōʻike nā kala KCMY 4 i nā hiʻohiʻona kala i manaʻo kūikawā ʻia no ka paʻi ʻana i ka ʻoihana. ʻAʻole lākou e ʻālohilohi. Inā paʻi ʻia ke ʻano kala ma nā ʻano media like ʻole me ka hoʻohana ʻana i nā lako hana hou no ka paʻi ʻana, hiki ke hoʻokaʻawale ʻia ke ʻano kala ma lalo o ke ʻano KCMY.

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

(ʻo ka maʻamau, e hoʻohālikelike ka hoʻolālā kiʻi i nā ʻokoʻa ma waena o nā kala ʻelua o ke kumu o ka paʻi rip)

Ua hoʻonohonoho ʻo Photoshop i ʻelua mau ʻano kala RGB a me KCMY e hana i kekahi ʻokoʻa. ʻO ka ʻoiaʻiʻo, ʻaʻole nui ka ʻokoʻa ma hope o ka paʻi ʻana, akā inā e hana i ke kiʻi ma RIP me ke kumu hoʻohālike RGB, e ʻike ʻoe i ka hopena paʻi he ʻokoʻa nui ia e hoʻohālikelike ʻia me ke kiʻi kumu.

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