ICC yog lub npe luv ntawm International Colour Consortium. Nws tau tsim nyob rau hauv 1993 los ntawm yim lub computer loj thiab cov duab tsim hluav taws xob. Lub hom phiaj yog los daws qhov teeb meem ntawm cov xim tswj kev sib raug zoo ntawm ntau yam duab tawm tswv yim thiab cov khoom tsim tawm. ICC txiav txim qhov xim. Kev tswj hwm yog nyob ntawm lub khoos phis tawj ua haujlwm, thiab siv "ICC Profile" (cov ntaub ntawv piav qhia xim) rau xim hloov dua siab tshiab. Yog tias ib qho kev tawm tswv yim lossis cov khoom siv tso tawm txhawb cov hom ntawv no, qhov tseeb xim hloov tuaj yeem ua rau ntawm lawv.
Raws li pom hauv daim duab saum toj no, txhua qhov xim thaiv yog xim xim, sib haum rau CMYK xim tus nqi, thiab tus nqi Lab sib raug yog ntsuas los ntawm qhov ntsuas, thiab tag nrho cov xim teev tau kos rau hauv Lab qhov chaw los tsim cov xim gamut . Lub ICC yog tsim los ntawm cov ntaub ntawv no thiab tsis muaj los ntawm ib tug tej yam algorithm.
Kev siv ICC yog dab tsi
Standardization yog ib qho tseem ceeb ntawm kev txhim kho kev tsim khoom niaj hnub, thiab ISO12647 tus qauv yog tus qauv kev lag luam ntawm kev lag luam luam ntawv. Muaj ntau ntau cov qauv kev lag luam hauv kev lag luam luam ntawv, xws li PSO, GRACOL, SWOP thiab JapanColor. Raws li lawv cov kev daws teeb meem, cov duab luam tawm tuaj yeem ua tau raws li cov qauv sib xws.
Tus qauv muab kev tswj hwm kev tshawb fawb thiab kev lees paub zoo thiab txhais tau tias rau kev lag luam, uas tuaj yeem siv los txhim kho qib kev tswj hwm sab hauv. Ua kom yooj yim rau kev sib pauv cov ntaub ntawv ntawm cov kws tshaj lij luam ntawv, prepress departments thiab cov neeg yuav khoom luam tawm.
Txhua lub teb chaws tus qauv ICC cov ntaub ntawv sib raug rau cov qauv tsim los ntawm cov koom haum sib txawv hauv cov xwm txheej sib txawv. Peb tuaj yeem ua kom peb cov khoom ua tau raws li ISO12647 tus qauv los ntawm kev siv ICC sib xws.
