Qhov txawv ntawm RGB thiab CMYK ntawm Inkjet tshuab luam ntawv yog dab tsi?
RGB xim qauv yog hais txog peb lub ntsiab xim ntawm lub teeb: Liab, Ntsuab, thiab Xiav, peb lub teeb xim thawj nrog ntau qhov sib txawv ntawm cov lej, tuaj yeem tsim ntau yam xim lub teeb, hauv kev xav, liab, ntsuab, xiav lub teeb tuaj yeem ua tau. sib xyaw ntawm txhua yam xim.
Hauv KCMY, CMY luv luv rau daj, cyan, thiab magenta. Cov no yog cov xim nruab nrab ntawm RGB (peb xim xim ntawm lub teeb) sib xyaw ua ke, uas yog cov xim ntxiv ntawm RGB.
Ua ntej nkag mus rau hauv cov ntsiab lus, cia peb saib cov hauv qab no:
Hauv daim duab, peb tuaj yeem pom tseeb tias cov xim xim CMY yog qhov sib xyaw sib xyaw, uas yog qhov sib txawv tseem ceeb, yog vim li cas peb lub tshuab luam ntawv thiab UV tshuab luam ntawv yog KCMY? pigments, tricolor mix feem ntau tsis yog ib txwm dub, tab sis ib tug tsaus liab liab, yog li tshwj xeeb dub number case K rau neutralize.
Kev hais lus theoretical, RGB yog qhov xim ntawm qhov xwm txheej, uas yog xim ntawm txhua yam uas peb pom ntawm peb lub qhov muag.
Hauv kev lag luam niaj hnub no, RGB xim qhov tseem ceeb yog siv rau qhov screen thiab raug cais raws li cov xim luminous. Qhov no tej zaum yuav yog vim cov xim purity ntawm lub teeb yog qhov siab tshaj plaws, yog li cov xim uas zoo tshaj plaws qhia txog RGB xim qhov tseem ceeb.Yog li peb tuaj yeem faib tag nrho cov xim pom raws li RGB xim qhov tseem ceeb.
Hauv qhov sib piv, KCMY plaub xim yog xim qauv rau kev lag luam luam ntawv thiab tsis muaj luminous.Raws li cov xim luam tawm ntawm ntau yam xov xwm los ntawm cov khoom siv niaj hnub luam ntawv, cov xim hom tuaj yeem muab faib ua KCMY hom.
Tam sim no cia saib qhov kev sib piv ntawm RGB xim hom thiab KCMY xim hom hauv photoshop:
(feem ntau, graphic design yuav sib piv qhov sib txawv ntawm ob xim rau rip luam ntawv)
Photoshop teeb tsa ob hom xim RGB thiab KCMY los ua qee qhov sib txawv.Qhov tseeb, qhov sib txawv tsis loj tom qab luam tawm, tab sis yog tias pom cov duab hauv RIP nrog RGB qauv, koj yuav pom cov txiaj ntsig luam ntawv yog qhov sib txawv loj piv nrog cov duab qub.
