01. RGB yog dab tsi?
RGB yog raws li ib tug dub nruab nrab, thiab ntau yam xim yog tau los ntawm superimposing lub brightness ntawm txawv proportions ntawm peb thawj xim (liab, ntsuab, thiab xiav) ntawm lub ntuj lub teeb.Txhua pixel ntawm nws tuaj yeem thauj khoom 2 mus rau 8 lub zog (256) ci ntsa iab ntawm txhua xim, kom peb cov xim raws tuaj yeem ua ke los tsim 256 mus rau 3 lub zog (ntau dua 16.7 lab) xim.Hauv kev xav, txhua yam xim uas muaj nyob hauv qhov xwm txheej tuaj yeem rov qab los.
Hauv cov lus yooj yooj yim, tsuav yog qhov tso zis yog lub vijtsam hluav taws xob, ces hom RGB yuav tsum tau siv.Nws tuaj yeem hloov kho raws li qhov xav tau ntawm ntau qhov kev tso tawm, thiab tuaj yeem kho cov ntaub ntawv xim ntawm cov duab ntau dua.
02. CMYK yog dab tsi?
CMY yog nyob ntawm qhov nruab nrab dawb.Los ntawm kev luam ntawv inks ntawm qhov sib txawv ntawm peb lub ntsiab xim (cyan, magenta, thiab daj), nws absorbs cov wavelengths coj mus rau hauv lub teeb xim thawj, thiaj li tau txais ntau yam xim cuam tshuam.
CMYK
Tsis yog nws txawv heev, qhov txawv ntawm CMY thiab CMYK yog dab tsi, qhov tseeb, vim hais tias nyob rau hauv txoj kev xav, CMY tuaj yeem hu tawm K (dub), tab sis tib neeg pom tias K (dub) siv ntau hauv kev xyaum, yog tias koj nquag. yuav tsum tau siv nws Hu tawm K (dub) los ntawm CMY, ib tug yuav pov tseg number case, thiab lwm yam yuav tsis raug, tshwj xeeb tshaj yog rau cov cim me me, txawm tam sim no nws tsis tuaj yeem sau npe tag nrho.Qhov thib peb yog siv 3 hom number case rau luam ntawv, uas tsis yooj yim rau qhuav, yog li cov neeg tau qhia K (dub).
CMYK yog hom plaub-xim luam ntawv, uas yog hom xim sau npe siv xim luam ntawv.Siv lub hauv paus ntsiab lus ntawm peb-thawj xim sib xyaw ntawm cov xim, ntxiv rau cov xim dub, tag nrho ntawm plaub xim yog sib xyaw thiab superimposed los ua lub npe hu ua "tag nrho-xim printing".Plaub tus qauv Cov xim yog:
C: Cyan
M: Magenta
Y: daj
K: dub
Vim li cas dub K, tsis yog B?Tias yog vim B nyob rau hauv tag nrho cov xim tau muab rau xiav (Blue) nyob rau hauv lub RGB xim hom.
Yog li ntawd, peb yuav tsum tau xyuam xim rau kev siv CMYK hom thaum ua cov ntaub ntawv los xyuas kom meej tias cov xim yuav luam tau du.
Thov nco ntsoov tias yog tias koj tab tom ua cov ntaub ntawv hauv RGB hom, cov xim xaiv tau ceeb toom kom ceeb toom Peugeot, uas txhais tau tias cov xim no tsis tuaj yeem luam tawm.
Yog tias koj muaj lus nug txog kev luam ntawv, thov xa email rauadmin@siumaipackaging.com.Peb cov kws tshaj lij luam ntawv yuav teb koj cov lus tam sim ntawd.
