Nyob rau hauv tus txheej txheem ntawm ntawv xov xwm layout, koj feem ntau ntsib cov ua cov xim duab. Thaum koj qhib xim xim, nws yuav nyob rau hauv RGB hom los yog CMYK hom. Yog li thaum siv Photoshop, nws siv RGB hom los yog CMYK hom rau xim duab ua? Tsab ntawv xov xwm no hais txog tus neeg sau txoj kev xav txog qhov teeb meem no.

Nyob rau hauv txoj kev siv Photoshop los tsim cov dluab, koj yuav tsum xub them nqi rau qhov tseeb uas rau ib qho duab uas tau qhib, txawm nws yog CMYK hom duab los yog RGB hom duab, tsis txhob hloov ntawm ob hom, cia nyob ib leeg Tus ob hom yog tig ib ncig. Vim tias, nyob rau hauv cov duab matrix duab editing software, txhua zaus cov duab xim qhov chaw hloov dua siab tshiab, ib feem ntawm cov duab yuavtsum yog ploj. Yog tias koj tig ib daim duab rau hauv RGB hom ib pliag thiab mam li hloov mus rau CMYK hom, cov ntaub ntawv poob ntawm daim duab yuav loj heev. Nws yuav tsum tau muab sau rau ntawm no tias daim duab hom siv rau cov phaj ua hauv cov txheej txheem ntawm cov ntawv xov xwm xim yuav tsum yog daim duab ntawm CMYK hom, txwv tsis pub luam tawm yuav tsis tau. Txawm li cas los xij, nws tsis txhais tias cov nyhuv luam tawm ntawm cov duab hauv CMYK hom thaum ua cov duab ua zoo heev, los yog nws nyob ntawm qhov xwm txheej no. Nws cov duab ua luam Photoshop ua duab xaiv RGB suab nyhuv yog muaj zog dua kev siv CMYK hom, tsuav tus duab ua tiav hauv RGB hom, thiab mam li hloov mus ua CMYK hom duab, tso zis zaj duab xis tau plated.

Hauv daim duab ua, yog daim duab qhib rau kev ua yog nws yog RGB hom duab los yog thawj daim duab tso cai rau xaiv RGB hom kev xa khoom siv cov kev tawm tswv yim ntawm scanner, qhov teeb meem no zoo dua rau cov hom ntawv ntawm cov ntawv xov xwm xim. . Thaum siv Photoshop luam theej duab thawj, cia li xaiv qhov RGB chaw xaiv nyob rau hauv qhov chaw xaiv xim nyob rau hauv cov ntawv qhia zaub mov hauv cov ntawv, thiab cov duab xim duab los ntawm kev luam tawm ntawm cov duab RGB. Hauv qab no, nyob rau hauv rooj plaub uas tsis tas yuav tsum tau hloov dua siab tshiab, daim duab hauv RGB hom tuaj yeem nrhiav tau, thiab daim duab no ua tiav hauv hom no, tshwj xeeb tshaj yog cov duab downloaded hauv Internet, thiaj li yuav xyuas luam cov duab ntawm daim duab, nws yog qhov tsim nyog yuav tau Siv RGB hom kev ua. Qhov kev pom no yog qhia los ntawm cov hauv qab no.

1. Hom RGB yog xim xim siv los ntawm txhua yam khoom siv kho qhov muag. Piv txwv, cov lus ua haujlwm hauv RGB hom. RGB hom muaj xim loj dua li cov qauv CMYK, yog li ntawd lub RGB hom tuaj yeem sawv cev ntau xim, tshwj xeeb tshaj plaws qaim thiab kaj xim (ntawm chav kawm, xim ntawm cov zaub yuav tsum raug kho kom cov xim ntawm cov duab tsis tshwm) . Cov xim no nyuaj rau luam tawm thaum luam ntawv. Qhov no kuj yog lub ntsiab yog vim li cas cov duab yuav tsaus ntuj thaum hloov cov duab xim hom ntawm RGB rau CMYK. Thaum koj hloov RGB hom dluab hauv Photoshop, koj yuav tsum xub xaiv lub CMYK Saib ua kom pom hauv cov ntawv qhia zaub mov (yog lub Cuab Yees Siv siv Suav version, xaiv qhov kev xaiv saib ua ntej hauv cov ntawv qhia saib bar thiab xaiv qhov CMYK). Uas yog hais, nws yog ib qho tseem ceeb heev uas yuav tau hloov cov duab hauv RGB hom thiab tso cov duab hauv CMYK hom kom cov xim ntawm daim duab ntawm cov duab tso saib uas tus neeg teb xov tooj pom yog qhov xim yuav tsum luam tawm. Qhov no yog ib txoj hauv kev zoo tshaj plaws uas kam nrog duab. Thaum Photoshop ua haujlwm nyob hauv CMYK hom, cov xim channel yog ib qho ntau dua RGB. Tsis tas li ntawd, nws siv RGB zaub hom simulate CMYK zaub nyhuv, thiab CMYK lub lag luam txoj kev sib txawv kiag li ntawm kev kho qhov muag raws li RGB. Yog li no, qhov ua tiav ntawm cov duab hauv CMYK hom qis dua, thiab qhov ua duab zoo tshaj kuj yog qhov tseem ceeb dua.

2. Qee cov ntxaij lim dej hauv Photoshop tsis txhawb CMYK hom thaum ua haujlwm nrog duab hauv Photoshop. Tsis tas li ntawd, txheej txheem ntawm cov duab feem ntau yog los ntawm ntau cov kev hloov maj mam. Piv txwv, tej zaum nws yuav tsum tau muab cov ntsiab lus ntawm ob peb cov duab. Txij thaum cov xim ntawm cov cheebtsam tsis tuaj yeem ua tib yam, lawv yuav tsum tau kho, lossis lawv kuj yuav tsum coj mus ua qee txoj kev, nrog kev ua haujlwm thiab ua haujlwm rau. Tsis hais cov nyhuv ntawm cov duab ua, tus neeg teb xov tooj xav tsim thiab khaws ntau yam kev hloov maj mam ua tau, thiab ua kom cov duab ua tiag thiab nplua nuj li, vim tias cov xim ntau ntawm RGB hom yog ntau dua lub hom CMYK . Yog li no, thaum ua cov duab hauv RGB hom, qhov chaw muaj xim zoo nkauj thiab ntau yam hloov maj mam editing cov teebmeem yuav tau txais thoob plaws hauv editing, thiab feem ntau ntawm cov teebmeem no, yog siv zoo, tuaj yeem fwm. Txawm hais tias nws tseem yuav tsum tau hloov dua siab tshiab rau CMYK hom thiab yuav twv yuav raug hu yog xim poob, nws yog zoo dua li poob xim ntawm daim duab los ntawm thaum pib.

3. Thaum hloov ib daim duab RGB duab rau hauv CMYK hom duab, qhov kev sib cais ntawm cov xim sib cais yuav ua rau lub luag haujlwm tseem ceeb ntawm cov duab hloov dua siab tshiab. Kev hloov ntawm cov xim tsis sib cais yuav zoo heev rau qhov kev hloov ntawm daim duab, thiab Photoshop duab ua software muaj peev xwm los tswj cov xim tsis sib cais. Uas yog hais tias, thaum nws tseem yuav tau hloov cov duab ua nyob rau hauv RGB hom rau hauv CMYK hom rau cov zis, xim tsis muaj peev xwm tau kev ua thaum lub hom kev hloov los ntawm qhov kev hloov ntawm cov xim sib cais ntawm cov txheej txheem thaum hloov txheej txheem.

4. Tam sim no, rau kev tshaj tawm cov ntawv xov xwm, cov duab siv yuav tsum tau muab khaws cia kom ntev, thiab nws yog qhov zoo rau khaws cov duab cov ntaub ntawv hauv RGB hom. RGB hom duab cov ntaub ntawv cov ntaub ntawv uas tau raug kho thiab kho yuav ua tau ib daim ntawv uas siv tau mus ntev cia, yog li ntawd RGB hom duab uas tau txais los ntawm cov archive yav tom ntej yuav siv tau rau cov zis sib txawv. Rau RGB hom duab cov ntaub ntawv cov ntaub ntawv yuav tsum reused nyob rau ntau lub neej yav tom ntej workflows, nws yog qhov yooj yim heev txawm tias txoj kev sib cais xim yog qhov system-qib xim lossis duab hloov hauv Photoshop.

5. Thaum luam ntawv, ntawv pov thawj, thiab muab duab ntxig siv cov tshuab luam ntawv ntau yam, cov khoom siv digital, los yog lub computer ntsuas, qhov tseem ceeb ntawm kev soj ntsuam (thiab kev ntsuas) qhov sib txawv ntawm cov duab thaij tawm ntawm cov khoom sau tawm saum toj no yog ntsuas qhov tsim nruab nrab grey. Tus nqi ntawm cyan, magenta, thiab daj yog sau rau ntawm qhov txho tshuav ntawm qhov kev sib txuas lus. Yog hais tias cov duab tau hloov mus rau CMYK hom, ces thaum reusing ib qho kev sib txawv ntawm cov zis, daim duab yuav tsum kho cov highlights, midtones, thiab ntxoov ntxoo ntawm CMYK duab, thiab hloov zuag qhia tag nrho gray tshauv thiab xim saturation. Yuav kom tsis txhob cuam tshuam qhov zoo ntawm daim duab sau, tus nqi dub nyob hauv daim duab yuav tsum tau hloov, tab sis yog tias daim duab luam tawm tsis kho cov ntaub ntawv dub, luam tawm tsis zoo yuav tshwm sim. Piv txwv, CMYK hom duab uas yog Ameslikas colour-cais rau ib tug zoo-sheetfed xovxwm yuav ua rau smudging yog luam tawm ntawm lub web xovxwm. Tus nqi dub nyob hauv daim duab yog loj, thiab txoj kev ua yuav tsuas yog kho CMYK. Txawv daim duab. RGB hom duab siv tau ntau dua RGB tonal khwv kom me nyuam zog, xim ntau dua. Txawm li cas los xij, tom qab daim duab yog xim sib cais hauv CMYK, tag nrho cov pixels hauv daim duab yog nyob rau hauv CMYK tonal ntau.

Raws li pom tau los ntawm qhov kev sib tham saum toj no, kev siv cov Photoshop rau txheej txheem cov xim duab yuav tsum tau ua hauv hom RGB. Txawm li cas los xij, nws yuav tsum tau muab sau thaum lub sij hawm ua haujlwm: cov duab ua hauv RGB hom yuav tsum xyuas kom tseeb tseeb ntawm daim duab xim thaum tawm hauv CMYK hom; thaum ua cov duab hauv RGB hom, nco ntsoov tias daim duab ua tiav tas ua ntej hloov mus rau CMYK hom duab. Nws yog qhov zoo tshaj kom tawm hauv cov duab hauv RGB hom kev thaub qab.

Ntxiv rau cov dluab nyob hauv RGB, Photoshop Lab xim hom kuj muaj cov yam ntxwv zoo. Hom RGB yog raws li lub ntsiab lus muag kho qhov muag, thaum CMYK hom yog xim hom uas cov xim muab coj los pom. Qhov zoo ntawm qhov kev ua haujlwm (Lab) hom yog tias nws ua rau qhov kev cuam tshuam ntawm thawj ob hom xim. RGB muaj xim ntau heev ntawm xiav thiab ntsuab, thiab muaj ob peb txoj kev hloov xim ntawm ntsuab thiab liab. CMYK hom poob ntau xim thaum editing thiab ua cov dluab, thiab Lab hom muaj cov sib nrauj. Kev Raug Mob. Lub Hom Lab no muaj peb txoj kev. L lub l haum sawv cev qhov ci, uas tswj cov ci ci thiab qhov sib txawv ntawm daim duab. Ib txoj hauv kev muaj cov xim ntawm ntsuab ntsuab (tsis tshua pom ci ntsa iab) los txho (nruab nrab ci ntsa iab) kom ci liab (siab tshaj plaws tus nqi). Cov b channel muaj cov xim xws li xim ntsuab (luminance tus nqi qis) los grey rau focal daj (siab luminance tus nqi). Lub hom phiaj (Lab) zoo ib yam li RGB, thiab cov xim ntawm cov xim ua kom muaj xim zoo nkauj. Tsuas yog tus nqi ntawm cov luminance channel cuam tshuam rau lub teeb thiab tsaus nti variations ntawm cov xim. Lub hom phiaj (Lab) hom yuav xav txog tias muaj ob hom ntawm RGB hom ntxiv rau ib qho chaw uas muaj kev ci ntsa iab. Txij ib txwm yog ntaus nruas thiab siv tau los kho cov duab (nrog rau cov duab gray) thiab zoo li RGB hom, ob peb zaug sai dua CMYK hom. Ib hom kev ua haujlwm (lab) guarantees tsis muaj xim ntawm CMYK ntau thaum ua xim hom hloov dua siab tshiab. Yog hais tias RGB hom duab hloov dua siab tshiab rau CMYK hom, ib theem nrab yuav tsum muab ntxiv rau cov kauj ruam ua haujlwm, uas yog, thawj zaug hloov dua siab tshiab rau Hom Hom. Nyob hauv tus txheej txheem ntawm typesetting ib cov ntawv xov xwm uas tsis yog xim, nws yog siv los hloov ib daim duab rau hauv daim duab grayscale uas siv hom Lab. Rau qee cov dluab ntawm RGB hom xa hauv Internet, yog tias koj tsis siv hom kev kawm (Lab) hom kev hloov thiab hloov mus rau grayscale, qee zaus koj tuaj yeem tsis tau cov duab thaum siv lub Founder Feiteng los yog Weiss typesetting software.

Nws tuaj yeem pom tau tias thaum muab cov duab thaij thiab ua cov duab, siv Cov Hom Lab lossis RGB hom ntau li ntau tau, thiab mam li hloov mus rau CMYK hom thaum nws tsis muaj kev tiv thaiv. Thaum koj tig mus rau hauv CMYK hom duab, tsis txhob rov qab yooj yim. Yog tias koj xav tau tiag, hloov mus rau Hom Txheej Txheem los ua cov duab. Yog thawj daim duab siv rau kev xa roj duab yog xim xim, tab sis daim duab yog siv nyob rau hauv grayscale layout, thaum nkag mus hauv daim duab nrog lub ntsej muag, tsis txhob muab cov duab qub rau hauv grayscale hom. Daim duab yuav tsum yog cov tswv yim hauv RGB hom. Tom qab ntawm RGB hom dab cov duab, nws yog thawj hloov dua siab tshiab rau hauv ib daim duab ntawm Chav Lab, thiab ces qhov kev sib txuas ntawm cov lus sib luag yog siv los xaiv cov duab L hauv cov duab grayscale rau luam ntawv.

Cov neeg feem ntau cov tswv yim muaj kev ncaj nraim nyob rau hauv tus txheej txheem ntawm kev ua daim duab. Dab tsi yog daim duab uas yuav tsum tau ncaj qha mus luam rau hauv hom duab yam duab los ntawm lub tshuab luam yeeb, thiab siv rau hom kab tom qab me me, thiab zoo li thaum luam ntawv. Tseem li ntawd. Qhov tseeb tiag, yuav kom tau qhov zoo ntawm daim duab, tsis txhob ntshai ntawm teeb meem, ua raws li tus txheej txheem khiav lag luam.
