Yog vim li cas rau qhov no yog qhov tus qauv tsim tawm ntawm kev siv tshuaj ntsuam los txiav txim seb cov xim zoo li cas. Yuav luag tag nrho cov ntxaij vab tshaus tau lawv tus kheej xim nrum, ib qho teeb meem ntawm ntau npaum li cas. Saib rau tib daim duab nrog cov ntxaij vab tshaus txawv me ntsis. Ntxiv mus, qhov screen yog ib hom teeb ci. Tom qab ntev, tus tib neeg lub qhov muag yuav tsim cov kev hloov kho me ntsis, kev siv rau ntawm cov xim cam ntawm lub vijtsam, thiab qhov kev txiav txim siab xim yuav poob qhov kwv yees, uas ua rau muaj qhov tsis sib haum xim xim kho. Yog li, qhov screen tsis yog ib qho cuab yeej zoo rau kev txiav txim siab cov xim.
Xib fwb kev txawj xim thiab kho kom zoo, thawj qhov khoom yog to taub cov ntsiab lus ntawm kev luam ntawv, cim tau cov xim ntawm kev sib koom ua ke, thiab paub cov ntaub ntawv qhia txog kev nyeem ntawv. Nyob rau hauv no txoj kev, nws yuav tsis tau meej pem los ntawm qhov screen, txawm tias koj hloov cov hauj lwm ntawm lwm lub screen, nws tseem muab qhov zoo tib yam thiab tagnrho xim kho cov nyhuv.
Ua ntej yuav ua kom pom cov duab, thawj qhov uas yuav tau ua yog ua kom muaj kev txiav txim siab zoo. Lub hauv paus ntawm qhov kev txiav txim siab yog qhov txho nyiaj ntawm kev luam. Qhov uas zoo nkaus li nruab nrab ntawm qhov nruab nrab ntawm qhov screen, yog tias luam tsis yog grey, nws txhais tau hais tias qhov no yog daim duab xim ib nrab. Yuav ua li cas kom twv tau qhov tshwm sim ua ntej daim duab sau, kwv yees li cas xim yuav biased, yog qhov paub tias tus designer xav tau tus tswv. Qhov kev paub ntawm no, tsis paub qab hau, yog tias koj to taub txoj ntsiab cai, ntxiv rau kev xyaum, koj tuaj yeem paub txog nws.
Hauv txoj kev xav, sib npaug ntawm CMY (cyan, magenta, daj) inks yuav tsum tov los ua ib qho nruab nrab grey. (Uas yog hais tias 50C + 50M + 50Y tuaj yeem tsim tau 50% grey). Txawm li cas los xij, lub ntiaj teb muaj tib lub thev plaub tsuas yog tsim los ntawm cov chaw tsim tawm. CMY lub peev xim rendering tsis zoo li qub. Ntawm lawv, magenta muaj lub luj tshaj plaws xim rendering fais fab, thiab cyan muaj qhov weakest xim rendering zog. Yog li, tus nqi ntawm CMY number case tib yam yuav tsis ua. Tsis muaj grey (yuav liab reddish gray), kom tau nruab nrab grey, koj yuav tsum tau nce qhov feem ntawm c (ink), uas yog lub hauv paus ntsiab lus ntawm grey tshuav (GreyBalance).
Piv txwv li, yuav tsim tau 50% nruab nrab av tshauv, qhov cyan yog 13% ntau dua li ntawm magenta, thiab tus nqi ntawm magenta thiab daj xiav npoo tuaj yeem hais txog kev sib npaug. Yog tias 30% tsis pom zoo cov tshauv, nws yuav tsum yog 9% ntau tshaj magenta. . Qee qhov sib txawv ntawm cov ntoo tshauv, magenta thiab cyan kuj tseem muaj cov sib txawv sib txawv. Ua tib zoo xyuam xim nyob rau hauv lub teeb grey, vim hais tias tib neeg qhov muag yog feem ntau rhiab rau xim xim qis. Qhov piv ntawm cyan thiab magenta nyob rau hauv ntau zaus yuav raug xa mus rau lub rooj ntawv txuas. Nco ntsoov tias cov duab ntawm no tsuas yog siv. Qhov tseeb, ntau hom ntawm cov phev yuav ua qhov feem ntawm qhov 2% mus rau 5%. Nws yog qhov zoo tshaj los piv nrog koj lub chaw tsim khoom luam. Lawv muab cov proportions ntau ntawm ntsuab thiab magenta mixed nruab nrab gray rau koj siv. Nws yuav yog qhov tseeb thaum koj txiav txim qhov no.
Nrog nruab nrab grey teev cov ntaub ntawv, nws yog sib npaug kom muaj ib tug siv xim kob, nws yog qhov yooj yim los txiav txim rau cov duab xim cam khwb cia. Nyuam qhuav pom ib feem ntawm daim duab uas muaj qhov nruab nrab ntawm qhov nruab nrab ntawm qhov nruab nrab, thiab siv cov cuab yeej tshuaj ntsuam xyuas kom pom cov teeb nyob rau hauv photoshop. Yog hais tias qhov kev sau ua ke nyob hauv kab nrog cov txheej txheem, koj tuaj yeem txiav txim siab tias daim duab tsis muaj xim sib tw, txwv tsis pub nws yuav ua raws qhov tshaj lossis Cov txheej txheem qis dua tus qauv, thiab daim duab raug kho.
Cov duab uas pom ntuj yog feem ntau ntawm kev ua tib zoo tsim los ntawm tus tsim qauv. Qee cov masters xim muaj peev xwm txawm kho cov duab tha xim nrog cov duab dub thiab dawb. Nyob rau hauv txoj kev ntawm kev kawm kho xim, nws tseem ceeb heev kom nkag siab lub tswvyim tseeb. Mastering kev sib raug zoo ntawm kev luam grey tshuav nyiaj yog qhov pib ua haujlwm ntawm cov xim.
Yog tias tus neeg ua haujlwm xav ua ib yam dab tsi zoo, nws yuav tsum tau hle nws cov cuab yeej ua ntej. Vim hais tias cov duab uas peb tau tsim muaj thaum kawg tau muab sau rau hauv daim ntawv luam tawm, to taub cov ntsiab lus, cov cwj pwm thiab cov kev txwv ntawm cov xim txheej txheem tseem ceeb heev rau kev tsim duab zoo. Yog tias tsis paub txog qhov no, nws zoo li kev caij nkoj yog tsis muaj compass. Txhua yam nyob ntawm guessing, nws yog ua tau mus cuag tus destination, thiab nws yuav tsis tau mus txog.
Nta hnub no, cov tshuab luam ntawv nrov tshaj tawm feem ntau nthuav qhia cov xim los ntawm cov qauv thiab kev tsim kho ntawm cov khoom siv. Cov duab sib txawv yog cov dots, squares, thiab elliptical cov ntsiab lus, thiab qhov loj ntawm cov dots yog qhia tawm feem pua. Feem ntau, qhov tsawg kawg nkaus tau sau rau ntawm plaub-xim offset xovxwm yog 2% thiab qhov siab tshaj plaws yog 85%. Cov zauv no sawv cev rau qhov feem ntawm qhov feem ntawm cov ntawv khu duav hauv ib qho chaw ib zaug xwb. Vim li cas qhov chaw siab tshaj plaws ntawm qhov taw qhia tsis yog 100%, uas yog vim qhov loj ntawm cov ntawv teev lus sau tseg thiab cuam tshuam los ntawm ob yam. Qhov zoo tshaj plaws yog tus nqi ntawm tus lej ntawm qhov luam ntawv (piv txwv li, ntau npaum li cas plaub xim muaj peev xwm muab absorbed rau ib cheeb tsam twg). Qhov thib ob yog "dotgain". Cov khaub noom ntau dhau los yuav ua rau daim ntawv dhau los, ua teeb meem rau kev ua khoom, xws li cuam tshuam rau daim ntawv sau ntawm daim ntawv deformation. Feem ntau, tag nrho ntawm cov plaub-xim luam ntawv tsis yog ntau tshaj 350%, yog li qhov siab tshaj plaws ntawm cov tib neeg luam tawm nws yuav tsis ntau tshaj 85%.
Cov txiaj ntsig kev nce nqi yog qhov tshwm sim ntawm kev sib txuam ntawm cov cwj mem zauv, luam ntawv siab, thiab ntawv xaj peev xim. Ntawm lawv, yam tseem ceeb ntawm kev luam ntawv thiab daim ntawv muaj ntau qhov kev txiav txim siab. Feem ntau, cov ntaub ntawv nplaum ci siab muaj ib qho chaw me me (muaj li 15% txog 20%), thiab cov ntawv xov xwm tuaj yeem ua tau ntau heev (li 25% mus rau 35%), yog li cov txheej txheem ib txwm siv los ua zinc phaj, thiab lwm cov ntaub ntawv luam tawm. Cov xim zoo tuaj yeem sib txawv. Kuj hais lus, luam ntawv siab yog qhov txawv txav uas lub koom haum luam tawm tau haujlwm. Qee cov tuam txhab luam ntawv txawm npaj cov nyiaj nruab nrab ntawm txhua lub tshuab luam ntawv nyob rau hauv ib txwm ua rau kev tswj cov khoom tsim tawm. Txij li thaum nyiaj npaum li cas los cuam tshuam cov xim kawg ntawm daim duab, nws yog qhov txawv txav uas peb yuav tsum tau coj mus rau hauv tus account thaum ua duab duab.
Ua ntej daim duab no tau rov qab, feem ntau yog txoj kev ntsuam xyuas, uas yog saib seb cov duab ntawm daim duab tom qab luam xa kab mob li cas. Feem ntau ntawm cov duab tau muab faib ua ob ntu, qhov ci ntsa iav (lub teeb sab nraud), lub nruab nrab thiab qhov tsaus ntuj nti (tsaus nti). Qhov no yog ib qho ntawm cov duab muab qhov teeb thiab tsaus theem ntawm tag nrho cov duab. Qhov teeb meem ntawm cov pib tshiab thiab xim kho yog kom them nyiaj ntau xim thiab tsis quav ntsej txog theem. Qhov tseeb, txawm hais tias daim duab no yog qhov tseeb lossis tsis yog, qhov qib yog qhov tseem ceeb tshaj.
Yuav kom txawj hloov theem, koj yuav tsum pib nrog lub teeb thiab tsaus qhov chaw. Lub teeb pom kev yog qhov tsawg tshaj plaws ntawm CMYK teev tag nrho cov nqi hauv daim duab, thiab tsaus nti yog qhov loj tshaj plaws ntawm CMYK teev tag nrho cov nqi. Cov chaw no yog pib thiab xaus cov ntsiab lus ntawm daim duab. Rau kev nkag siab yooj yim, koj tuaj yeem xav txog daim duab ua ib chav. Lub teeb pom kev yog lub teeb ci hauv chav. Yog tias lub teeb ci ci ci ntsa iab, lub tsev tag nrho yuav ci ntsa iab. Yog lub teeb ci tsaus nti, tag nrho lub tsev yuav dim; yog tias lub teeb ci ntsa iab mus rau xiav Xim, ces txhua qhov ntawm tsev yuav tau muaj hawj xiav. Yog li no, seb qhov nqis ntawm qhov chaw ntawm lub teeb puas muaj tseeb txiav txim siab txog qib thiab xim nrig ntawm tag nrho cov duab. Qhov yees duab yees duab tus nqi yog 5C3M3Y los yog 4C2M2Y. Yog hais tias qhov teeb meem ntawm lub teeb ntawm qhov kev ntseeg no, nws yuav luag yog qhov theem thiab hawj ntawm tag nrho daim duab yuav tsum tau kho.
Los ntawm tib lub cim taw qhia, yog tias tus nqi ntawm qhov tsaus ntuj nti tsis raug, qhov kev ua tiav ntawm tag nrho cov duab yuav raug zoo heev. Yog hais tias qhov tsaus ntuj nti yog teeb tob dhau (qhov tseem ceeb loj heev), cov ntsiab lus ntawm qhov tsaus nti yuav tsis raug qhia, thiab nws yuav ua dub. Yog hais tias qhov tsaus ntuj nti tsis txaus, cov dub yuav tig txho thiab nws yuav saib tsis tau zoo thiab tsis muaj tseeb. .
Xaiv txoj kev kaj thiab txoj hauj lwm uas tsaus ntuj yog lub hauv paus rau kev siv lub hwj chim ntawm daim duab. Los ntawm txoj kev to taub ntawm lub ntsiab lus tom qab lub teeb pom kev thiab qhov tsaus nti nqi, tsis muaj teeb meem dab tsi koj ntsib, dab tsi ntawm qhov screen koj xaiv, koj yuav tau txaus siab rau nws. Cov duab xim zoo nkauj.
