Hauv kev luam ntawv, qhov teev yog feem ntau yog siv los ua cov chav tsev yooj yim. Vim tias cov dots yog nyob rau hauv tus txheej txheem ntawm kev ntsuam xyuas, luam tawm thiab luam ntawv mus rau lub substrate, lawv yeej ib txwm nyob rau hauv tus txheej txheem ntawm kev hloov. Cov kev hloov ntawm cov teev yog tsuas yog nce, thiab feem ntawm ntug qhov dav tuaj sab nraud, ua rau cov duab tsaus nti tag nrho, cov txheej ntawm lub suab tsaus nti ploj, thiab qhov ci ntsa iab thiab qhov nruab nrab cov xim. Yog hais tias tus ua tsis zoo, nws tsis muaj txiaj ntsig kom hloov ntau tshaj plaws rau daim duab. Nws yog qhov tsim nyog yuav tau nrhiav kom paub qhov nce ntxiv ntawm cov teev thaum lub sij hawm kho tshiab kom tau txais cov nqi them sib piv, thiab them qhov nce ntawm cov ntawv teev hauv cov ntawv luam.
Cov duab thiab cov yam ntxwv ntawm cov dots
Tsoos dot daim duab muaj cov square dots thiab vas dots, thiab ntau cov ntsiab lus ntxiv uas siv los siv. Cov dots ntawm tus loj tib yam muaj qhov sib txawv ntawm cov teeb meem vim lawv nyias txawv nyias, thiab qhov txiaj ntsim qhov nce nqi tseem txawv. Txij li thaum lub teev yog sab nraud sab nraud nrog nws ntug thaum luam ntawv, qhov ntev ntawm qhov ntsuas ntawm qhov teev, qhov loj tshaj qhov nyiaj tau nce.
Thaum cov dot enlarged, muaj ib txwm yog ib feem ntawm qhov sib tshooj pib. Nyob rau hauv qhov no, qhov sib tshooj ntawm cov dots ua rau muaj kev cia siab nce rau hauv qhov ceev ntawm qhov teeb meem luam tawm, yog li rhuav tshem qhov ua kom tiav ntawm qhov teeb meem luam tawm thiab ua rau qee cov tonal poob. Piv txwv, gradients tuaj yeem ua rau tsis sib xws ntev vim qhov kev sib tw dhia. Hauv kev sib piv, daim duab zoo ntawm cov taw tes saw zoo dua vim tias nws cov ceg tawv sib nrauj khaus midtone thiab lub ncej puab yog faib ob zaug, uas txo cov kev dhia dhia. Vim li no, yog hais tias daim duab me me thiab mos, xws li cov duab zoo li cov duab, yuav tsum siv cov saw dot; Yog tias cov duab zoo ib qho loj, ib lub xwmfab lossis vas-dot tuaj yeem siv.
Qhov zoo tshaj ntawm qhov khoom poob
Hauv kev luam ntawv, qhov feem pua ntawm qhov kawg teev yog feem ntau loj tshaj qhov feem pua ntawm cov teev ntawm cov xim sib cais. Qhov tshwm sim no yog hu ua kev nce qib. Yog vim li cas rau qhov nce hauv qhov loj me muaj xws li qhov nyiaj nce tuaj los ntawm kev luam ntawv siab, teev tau nce los ntawm cov ntawv tsis txaus thiab tsis muaj absorption thiab diffusion los ntawm cov yam ntxwv ntawm cov ntawv thiab cwj mem. Uas yog hais, sib txawv cov txiaj ntsig teebmeem yuav raug tsim rau cov ntawv luam sib txawv thiab cov ntaub ntawv sib txawv; cov dots ntawm ntau qhov ntau thiab tsawg yuav nce hauv txoj kev tsis sib raug zoo. Qhov kev nce qhov tsim tau los ntawm tus yam ntxwv ntawm daim ntawv thiab tus cwj pwm feem ntau pom muaj qee txoj cai nthuav dav; nyob rau hauv cov txheej txheem ntawm phaj-txiav duab zis thiab luam ntawv, qhov nce nqi nce ntxiv vim khoom siv thiab cov khoom siv, thiab qhov nce Nws tuaj yeem txo los ntawm kev hloov cov luam ntawv.
Hauv cov ntsiab lus, qhov kev nce nqi yog qhov teeb meem uas tsis muaj kev cuam tshuam vim muaj tej yam hauv kev luam ntawv thiab khoom siv, thiab vim li ntawd, nws tsis yooj yim kom tau txais ib qho luaj li cas ntawm qhov teeb meem luam tawm. Rau qhov kawg no, qhov txiaj ntsig ntawm qhov kev nce nqi yuav tsum tau them rau hauv kev npaj siv computer thiab kev sib cais xim. Cov tswv yim yooj yim yog ua ntej kom txo qhov ntsuas kom pauv hauv cov xim sib cais, thiab ces cia nws nthuav mus rau qhov loj me me raws li txoj cai nce ntawm cov teev hauv cov ntawv luam.
Nws yuav tsum raug qhia hais tias cov kev luam ntawm cov luam tawm tsawg tshaj qhov kev luam ntawv, thiab qhov txiaj ntsim ntawm qhov yuav tsum txawv ntawm kev luam tawm.
Txhim kho cov nyiaj rau qhov nce hauv Photoshop
Qhov ncaj nyhuv ntawm qhov txiaj ntsim ntawm kev nce siab yog ua kom luam tawm thiab luam cov duab thawm tsaus ntuj thiab ib tsos tsaus tsawv, tshwj xeeb tshaj yog rau ntawm ib nrab. Cov nyiaj raug txiav rau qhov txiaj ntsim tau nce siab yog los ntawm cov cai hauv qab no:
1) Siv cov cuab yeej Curves hauv Photoshop kom ncaj qha cov ntaub ntawv hauv daim duab yog qhov rov qab tshaj thiab cov uas yooj yim. Nws yog ib qho tseem tau siv ib lub cuab tam zoo sib xws nyob rau hauv lub hauv ntej-kawg luam software kom teem tau qhov kev tshawb fawb tau txais daim phiaj nqus mus muab cov ntaub ntawv tiv thaiv. Piv txwv, yog tias qhov teev tau nce mus rau 10%, ces tus taw tes tswj tau muab tso rau 50% ntawm qhov kev nkhaus laus, thiab tus taw tes yog kho rau 40% ntawm cov suab lus, ces qhov kev luam thiab ua tiav cov duab zoo li cov duab thawj qhov nruab nrab Brighter, tab sis thaum luam ntawv lossis luam ntawv, 40% ntawm cov dots yuav dim mus rau 50%, ib yam li qhov qub.
2) Photoshop muaj ob qhov chaw nyob rau hauv lub ntsej muag ntawm qhov nce qhov nce siab: ib qho yog tus qauv txheem thiab ib qho yog qhov nkhaus hom.
Nyob hauv tus qauv hom, txij thaum qhov txiaj ntsim ntawm qhov txiaj ntsim tau muaj feem xyuam rau txoj kev siv nyiaj hauv nruab nrab, hauv cov qauv siv, qhov teev poob qhov nce ncaj qha mus hais txog qhov nruab nrab tone dot, uas yog, qhov 50% ntawm qhov kev nce nqi. Piv txwv, teem caij 20% teev nyiaj tau los txhais tau hais tias cov ntawv teev npe nrab yuav raug luam tawm ntawm 70%. Tsis tas li ntawd, nyob rau hauv cov xim luam ntawv tso tawm hom, cov nyhuv ntawm qhov txiaj ntsim ntawm cov xim tseem heev, thiab txawv dot, inkjet ceev thiab tshuab luam ntawv ua qauv yuav coj txawv qhov sib txawv ntawm cov nyiaj tau los. Cov hom no feem ntau muaj tseeb.
Nyob rau hauv txoj kev ua nkhaus, qhov txiaj ntsim tsam tau muab teev los ntawm cov txheej txheem thiab CDYK plaub-xim channel. Nws tuaj yeem teev qhov txiaj ntsig ntawm qhov yuav tsum tau mus rau ntau tshaj 13 theem, thiab qhov tseeb yog siab dua tus qauv siv. Cov txheej txheem hauv dej yog qhov qis hom nyob rau hauv rooj plaub ntawm txhua tus tib hom kev ua haujlwm. Lub sij hawm no, qhov nce nqi ntawm txhua channel ntawm CMYK yog yuam kom zoo ib yam, uas yog ib qho kev txuas ntxiv ntawm cov qauv siv. Nthuav cov nyiaj poob haujlwm nce siab los ntawm 50% ntawm ib qho taw tes rau tag nrho gray ntaiv ntau. Yog tias qhov ntsuas ntawm lub kauj ruam ntawm thawj kauj ruam yog 20% grey, qhov ntsuas qhov ntsuas yog 30%, ces 30 yuav tsum tau sau rau hauv 20% kem ntawm lub thawv ntawv. Yog hais tias qhov txiaj ntsig qhov txiaj ntsig zoo tau muab siv raws plaub xim raws, ntsig txog, nws tsis yog muab qhov teev tsam qhov nyiaj ntawm txhua tus cwj pwm xim, tab sis kuj tseem tuaj yeem txheeb cov gray tshuav khoom ntawm tus cwj mem. Tau txais qhov ntsuas qhov nce, nws yog qhov yuav tsum tau ntsuam xyuas lub CMYK plaub-xim gradient tus qauv ntawm cov qauv xeem xws li ib nqe lus hais saum toj no, thiab ua tib qhov kev ntsuas thiab sau ua haujlwm ua tus pas ntsuas.
3) Khaws cov twj tso zis ua haujlwm cua kab nyob rau hauv EPS hom, thiab kho cov zauv los ntawm RIP thaum nws tso zis. Xaiv cov ntaub ntawv / nplooj teeb hauv Photoshop thiab tom qab xaiv Xaiv Kev Hloov mus tso saib lub nkhaus mapping cuab tam zoo ib yam li Curves. Koj tuaj yeem sau rau hauv lub npov ntawm txhua lub suab lus raws li qhov ntxoov ntxoo txawv, thiab xaiv cov hom ntawv EPS. Thiab nyem qhov IncludeTransfer Muaj nuj nqi khawm cia nyob hauv EPS hom ntawv. Cov duab lus tsis hloov nyob rau hauv cov kev kho no, tab sis qhov kev ua haujlwm hloov yog kos nyob rau hauv cov ntaub ntawv rau lub RIP los pab kom them nyiaj rau qhov nce qhov qub raws li tau piav saum toj no.
Xaus
Hauv txhua txoj kev luam ntawv, muaj qhov tshwm sim ntawm qhov kev nce nqi, thiab txhua txoj kev luam ntawv thiab txhua txoj kev luam ntawv muaj qhov tseeb ntawm cov ntsiab lus. Yuav kom compensate rau inevitable teev kev nce qib hauv luam ntawv. Txhawm rau kom them nyiaj rau kev lag luam tsis pom kev hauv luam ntawv, nws yog ib qho tseem ceeb rau kev tswj hwm thiab kho cov hauj lwm ua ntej. Nws yuav tsum tau ensured tias feem ntawm txhua kauj ruam ntawm cov teev yog ruaj khov thiab tsis tuaj yeem cuam tshuam txog kev luam cov duab hauv cov txheej txheem tom ntej.
