Tus qauv tsim
Thaum npaj thiab ua ib phaj, daim tseem cia rau plaub xim: cyan (C), magenta (M), daj (Y), thiab dub (K). Txoj kev sib cais ntawm cov xim yog dab tsi?
A: Muaj ntau plhom xim ntawm qhov screen, xws li xim kos duab los yog xim duab. Nws yuav luag tsis tau luam cov kaum tawm txhiab tus xim nyob rau hauv ib lub xim. Cov plaub-xim luam yeeb siv los luam ntawv. Ntawd yog, yog thawj xim-decomposed thiab muab faib ua plaub xim ntawm cyan (C), magenta (M), daj (Y), thiab dub (K), thiab tom qab ntawd ces yog xim. Qhov sib txawv ntawm "sib cais" yog raws li txoj cai ntawm kev rho tawm xim, uas siv cov xim liab, xim ntsuab thiab xiav xim los xaiv lub teeb ntawm ntau lub wavelengths, thiab decomposes thawj qhov xim daj, daj thiab xiav xim. Nyob rau hauv cov xim sib cais, xim xim absorbed los ntawm cov xim xim yog xim sib txuas ntawm cov xim xim nws tus kheej, yog li ntawd rau cov duab thaij duab, cov duab dub thiab cov duab dawb tsis zoo, thiab tom qab ntawd ces qhov screen ntxiv tsim ib qho kev tsis zoo ntawm cov teev, thiab thaum kawg cov xim yog tau theej thiab qhuav. Phaj. Qhov no yog qhov cai tshaj plaws ntawm kev kos duab sib cais.
Vim tias peb tuaj yeem tsos nqaij daim tawv, qauv thiab hloov cov xim qub rau hauv cov ntaub ntawv los ntawm cov khoom siv tshuaj xa tawm, uas yog, cov xim thawj xim (red) (R), ntsuab (G), thiab tib txoj kev raws li photolithography. Xim (B) peb xim, thiab digitized, thiab tom qab ntawd siv lub computer los ua lej cov ntaub ntawv digital rau plaub xim ntawm c (C), magenta (M), daj (Y), thiab dub (K).
Vim li cas thiaj yuav tsum tau npaj cov duab yuav tsum tau kuaj?
LUS TEB: Vim tias kev luam ntawv txiav txim siab tias cov ntawv luam tsuas siv tau cov ntawv teev lus los ua me nyuam lub suab ntawm qhov tseem ceeb, yog tias daim duab loj, nws yuav pom tias muaj ntau ntau ntau qhov sib txawv. Peb pom hais tias qhov pom ntawm qhov txawv yog qhov sib txawv, tiam sis lawv txhua tus nyob hauv tib qho chaw loj. Qhov no yog vim tom qab thawj daim duab raug kuaj xyuas, daim duab yog muab faib ua ntau qhov teeb meem, uas yog, cov ntaub ntawv duab nruam yuav hloov mus rau qhov tsis sib txawv. Cov ntaub ntawv duab. Qhov loj dua qhov dot, qhov tsaus ntuj nti thiab ib tsos tsaus tsawv txheej; qhov me me qhov dot, qhov sib dua ntawm cov xim, thiab lub zog txheej. Qhov loj ntawm qhov chaw ruaj khov ntawm txhua qhov teev yog txiav txim siab los ntawm cov xov tooj ntawm cov npo. Piv txwv, yog tias muaj pes tsawg tus dots yog 150 lpi, muaj 150 cov dots nyob ntev lossis dav ntawm ib nti. Qhov chaw ntawm qhov chaw nyob thiab qhov loj me yog ob lub tswv yim sib txawv. Piv txwv li, C50% txhais tau hais tias qhov ntsuas loj npaum li cas rau 50% ntawm qhov chaw nyob qhov chaw, thiab 100% txhais tau hais tias qhov ntsuas me nyuam npog qhov chaw nyob qhov chaw, uas yog hu ua "printing". Hauv teb, 0% tsis muaj cov dots, tsuas yog qhov chaw qhov chaw, tsis muaj tus lej muab luam tawm hauv qhov chaw no. Obviously, qhov loj tshaj tus nets, qhov me me qhov chaw nyob los ntawm cov dots, thiab ntau txheej uas tau piav, qhov ntau muag heev. Qhov tseeb, qib thiab xim ntawm daim tseem yog tswv cuab los ntawm hom kev dai nets.
Dab tsi yog qhov xim xim?
A: Cov xim luam yeeb yog xim muaj li ntawm feem pua ntawm C, M, Y, thiab K, vim li ntawd nws yog qhov tsim nyog ntxiv hu nws cov xim sib xyaw. C, M, Y, thiab K yog plaub hom xim siv luam ntawv. Thaum luam ntawv thawj xim, cov plaub xim muaj lawv cov xim xim. Cov dots ntawm cov xim yog kaw rau ntawm daim phiaj xim. Cov dots no yog tsim los ntawm qhov kev ntsuas ntawm halftime, thiab plaub daim phiaj xim muab tso ua ke. Thawj xim txhais. Kho qhov loj thiab qhov kis ntawm cov xim sib txawv xim yuav tsim lwm yam xim. Qhov tseeb, plaub daim xim luam tawm ntawm daim ntawv yog nyias nyias, tab sis lawv ze zog heev. Vim tias peb qhov muag muaj qee cov kev txwv hauv lawv qhov kev daws teeb meem, lawv tsis tuaj yeem sib txawv. Lub tswv yim pom peb tau txais yog cov nyhuv ntawm cov xim ntau yam, yog li ua tau ntau hom thawj xim.
Y, M, C synthesize yuav luag txhua xim, tab sis kuj xav dub, vim hais tias cov dub ua los ntawm Y, M, C yog impure, yuav tsum tau dawb ntshiab dub thaum luam ntawv, thiab yog tias Y, M, C yog siv los tsim Black yuav muaj teeb meem hauv zos ntau dhau.
Dab tsi yog qhov cuab yeej rau cov xim desktop publishing system? Dab tsi yog qhov software?

3 Tom qab tus neeg mob tau xaus cov ntaub ntawv, xa cov ntaub ntawv mus rau qhov chaw tso zis los mus tsim tawm zaj duab xis. Lub laser imagesetter ua haujlwm hauv cov lus PostScript. Tus RIP (Raster Image Processor) qhia txog qhov teeb tsa ua duab bitmap thiab muab faib ua C (cyan), M (magenta), Y (daj), thiab K (dub) xim. ntawv. Yog hais tias qhov kawg yuav tsum muaj tus tsim tsis yog cov zis zaj duab xis, tiam sis ib qho loj xim inkjet qauv, cov zis yuav ua tau nrog inkjet lub tshuab luam ntawv.
Yuav ua li cas xaiv cov ces kaum tawm tau zoo?
A: Yuav kom tsis txhob ntaus lub vas, hauv kev tshawb xav, qhov txawv ntawm cov xim yuav tsum yog 22.5 degrees, tab sis kev xyaum qhia tau hais tias plaub ces kaum ntawm 15 degrees, 45 degrees, 75 degrees thiab 90 degrees yog qhov zoo, thiab cov xim daj version yog visually stimulating. Nws yog ib qho uas tsis muaj zog thiab tsis pom kev zoo. Yog li, nws feem ntau teem ntawm 90 degrees. Lub zeem muag yog feem ntau nkag siab txog 45 degree lub kaum ntse ntse. Feem ntau, lub ntsiab xim ntawm daim tseem yog magenta los yog cyan yog 45 degrees. Piv txwv, rau lub ntuj xiav thiab huab huab, xiav tus qauv yuav tsum tau teem rau 45 degrees. Rau yav sawv ntxov glow thiab lub hnub poob, tus magenta version yuav tsum tau teem rau 45 degrees, thiab cov xuab zeb uas tsis yog-45 degree yuav tsum tau teem. Rau 15 degrees, qhov dub version yog teem rau ntawm 75 degrees.
Tom qab cov ntaub ntawv tso zis, tsuas yog cov dub version muaj ces kaum, thiab lwm yam versions tsis muaj cov ces kaum. Kuv yuav ua li cas?
A: Tib txoj kev yog rov tsim tawm, thiab hloov xim ntawm lub ces kaum ntawm 100% BK mus rau 100 00% M100% Y100% BK, yog li, hloov cov duab dub rau plaub-xim dub.
Kuv yuav ua li cas yog tias cov xim version thiab cov xim thawj qhov tseeb tsis muaj tseeb?
A: Re-export tag nrho cov xim phiaj. Txawm hais tias qhov no yog txoj kev ruam tshaj plaws, nws yog txoj kev nyab xeeb tshaj plaws.
Daim duab daws teeb meem yog dab tsi? Vim li cas thiaj hais tau nws?
A: Kev daws teeb meem ntawm cov ntawv luam tawm tau raug muab tso rau hauv qhov tseem ceeb ntawm kev luam ntawv. Peb paub tias cov duab muaj cov duab siab muaj ntau pixels ntau tshaj qhov sib txawv ntawm cov duab qis, thiab cov duab cov ntaub ntawv ntau dua thiab cov ntsiab lus meej. Ib qho laj thawj los txiav txim siab txog daim duab daws teeb meem yog xav txog qhov kev xav tau tawm. Vim cov duab siv rau ntau lub hom phiaj, kev txiav txim siab yuav tsum raug txiav txim siab raws li lub hom phiaj ntawm daim duab. Yog tias tus duab tso tawm ntawm qhov screen, qhov kev daws teeb meem yog 72Dpi los yog 96Dpi; yog tias nws siv rau kev tso zis tawm 600Dpi, nws xav tau 150Dpi duab daws teeb meem; Yog luam, nws xav tau 300Dpi siab. Tsho. Daim duab daws teeb meem yuav tsum tsim nyog: yog qhov kev daws teeb meem siab heev, khiav ceev qeeb qeeb, qhov chaw khoob khoob khoob loj loj, thiab txoj hauv kev ua haujlwm zoo tsis tau ntsib; Yog hais tias qhov kev daws teeb meem tsis txaus, qhov kev qhia ntawm cov duab lus tsis yog raws li txoj cai zoo.
Vim li cas cov dluab yuav tsum muaj ib daim duab duab hom? Nws muaj ob peb daim duab cov ntaub ntawv tawm tswv yim uas feem ntau muab kev koom tes rau hauv ntawv. Dab tsi yog qhov ntawm txhua tus?
A: Cov ntaub ntawv hom ntawv txiav txim siab seb hom ntaub ntawv yuav tsum tau muab khaws cia rau hauv cov ntaub ntawv, ua li cas cov ntaub ntawv tau tshaj cov kev siv ntau yam, thiab ua li cas cov ntaub ntawv sib pauv cov ntaub ntawv nrog lwm cov ntaub ntawv. Txij li thaum muaj ntau ntau cov duab rau cov duab, cov duab ntawm daim duab yuav tsum txiav txim siab raws li lub hom phiaj ntawm daim duab.
Daim duab cov ntaub ntawv tawm tswv yim uas siv los tsim yog:
TIFF hom: TIFF yog ib daim duab kos duab rau txuag cov dluab ntawm cov xim raws. Qhov loj tshaj plaws yog tias cov duab tsis txwv los ntawm kev khiav hauj lwm lub platform, thiab siv tau tsis hais txog PC, MAC los UNIX. Nws tuaj yeem khaws alpha raws thiab khaws cov ntaub ntawv sib cais xim rau hauv ib qho ntaub ntawv.
Hom ntawv EPS: Hom ntawv EPS siv rau kev luam ntawv thiab luam ntawv. Nws yuav khaws Duotone cov ntaub ntawv, khaws Alpha raws, thiab khaws cov lus qhia thiab kev tshuaj ntsuam.
GIF yog hom 8-ntsis uas tsuas qhia tau 256 xim. Nws yog ib qho hom rau kev tawm tswv yim sib txuas network.
PSD yog siv los ua ib qho kev hloov ntawm cov duab ua kom txuag tau cov channel thiab txheej ntawm daim duab tom qab hloov kho. Cov hom ntawv tsis zoo heev, thiab Photoshop tsuas siv tau nws, thiab ob peb lwm daim ntawv sau npe txhawb nws.
JPE yog ob qho tib si ib hom ntaub ntawv thiab txoj kev nruj. Qhov no compression yog swb, thiab tus poob tsis zoo li qub. Qee cov me me dhau los ua kom pom qhov muag ntawm tib neeg qhov muag.
Dab tsi yog cov naj npawb ntawm cov duab ntxig rau cov duab luam tawm? Dab tsi yog kev sib raug zoo ntawm daim duab daws teeb meem, kev daws teeb meem, thiab laser imagesetter tso tawm?
Lus Teb: Vim tias qhov teeb meem tshwm sim muaj li ntawm cov dots, tus naj npawb ntawm cov ntawv ntsuam xyuas hauv cov duab luam yog hais txog cov kab ntawm ib nti ntawm cov teeb meem luam tawm hauv kab rov tav los sis ntsug, qhov ntawd yog, tus naj npawb dai nets. Tus nab npawb ntawm cov ntxig yog hu ua vim cov ntawv luam ntxov tshaj plaws yog wired. Chav tsev ntawm cov xov tooj ntawm cov kab dai yog Kab / Thoob (LPI). Piv txwv li, 150Lpi txhais tau hais tias muaj 150 lub cab cab cab ib nti. Ntxiv ib daim duab rau daim duab, qhov loj dua cov nets, ntau tus nets, denser cov zauv, thiab zoo dua rau theem ntawm kev ua tau zoo.
Vim hais tias lub computer duab yog ib qho matrix teev, uas yog, ib lub pixel (qhov me tshaj plaws ntawm daim duab hu ua pixel). Duab daws teeb meem tuaj yeem pom kev to taub tias pes tsawg pixels cov sawv cev los ntawm ib txoj kab rau hauv ib chav tsev ntev hauv kab sab tav los sis ntsug. Qhov ntau pixels siv los piav qhia txog kab no, qhov ntau dua qhov kev daws teeb meem. Chav tsev ntawm daim duab daws teeb meem yog feem ntau Pixels PerInch (pixels ib nti), feem ntau yog hais ua lus Askiv li PPI. Piv txwv, yog hais tias tus duab muaj ib qho kev txav ntawm 300 PPI, nws txhais tau hais tias nws muaj 300 pixels ib nti hauv txoj kab rov tav los sis ntsug; Yog hais tias qhov daws teeb meem ntawm cov duab 720I, nws txhais tau tias nws muaj 72 pixels ib nti hauv txoj kab los yog txoj kev ntsug.
Qee cov cuab yeej siv tau zoo ib yam li cov duab ntawm cov duab, tshwj tsis yog tias lawv tau muab tso rau hauv cov dots, yog li lawv raug sawv cev Dot Per Inch, lossis DPI rau luv luv. Piv txwv, tus duab scanner nrog 1200 DPI daws teeb meem muaj ib cov duab duab ntawm 1200 dots ib nti, lossis pixels. 3600DPI laser imagesetter muaj ib cov qauv zis muaj ntawm 3600 laser dots ib nti.
Cov teeb meem PPI thiab LPI cov duab luam (cov xov tooj ntawm cov vijtsam) muaj feem xyuam thiab txawv: cov duab daws teeb meem siab dua qhov kev daws teeb meem, feem ntau 2 × 2 pixels tsim 1 teev, uas yog, LPI yog DPI Txog ib- ib nrab.
Pantone yog dab tsi? Vim li cas thiaj siv Pantone los tsim cov xim?
A: Pantone yog ib hom tshuaj cuas nto moo hauv Tebchaws Meskas thiab tau dhau los ua cov qauv kev luam xim. Nws tau ua tag nrho cov phev ua los ntawm nws tus kheej rau hauv chromatograms thiab xim cov qauv. Pantone's color code tau dhau los ua ib hom lus lees paub txog xim sib txuas lus. Cov neeg siv yuav tsum muaj xim tshwj xeeb thiab lawv tuaj yeem ua raws li xim xim. Vim muaj kev siv ntau ntawm Pantone xim code, lub tshuab tsim software muaj lub Pantone xim qiv thiab siv nws rau xim txhais. Thaum teev cov xim uas siv cov Pantone xim qiv ntawv, qhov kev xaiv xaiv yog Pantone xim, tab sis nws yuav tsum raug sau tseg tias feem ntau cov xim Pantone yog cov xim xim. Yog hais tias koj xav muab tsim rau hauv plaub xim, koj yuav tsum teev hom xim rau cov xim thawj. Daim duab 1-13 yog ib qho kev sib txuas uas piav txog Pantone xim.
Dab tsi yog xim sib cais? Yog sib cais xim tseem ceeb heev? Yuav ua li cas xim sib cais hauv Photoshop?
A: Sib cais yog ib lub tshuab luam tawm uas yog hais txog lub zauv ntawm cov xim ntau ntawm plaub xub thawj xim: daj, magenta, cyan, thiab dub. Hauv computer-luam qauv lossis duab nraaj tsim duab, xim sib cais ua haujlwm. Nws yog los hloov xim hom ntawm cov duab scanned los yog lwm qhov duab rau hauv CMYK hom.
Feem ntau, cov duab scanned yog nyob rau hauv RGB hom, thiab cov duab noj nrog lub koob yees duab digital kuj yog hom RGB. Feem ntau ntawm cov duab downloaded hauv Internet yog nyob rau hauv RGB xim hom. Yog koj xav sau, koj yuav tsum faib cov xim rau plaub xim: daj, magenta, cyan, thiab dub. Qhov no yog qhov yuav tsum tau luam tawm. Yog hais tias cov duab xim hom yog RGB lossis Lab, nws puas tuaj yeem tso tau cov teev rau ntawm K version, uas yog, tus txhais lus RIP tsuas txhais cov ntaub ntawv xim ntawm daim duab ua grey.
Hauv Photoshop, txoj haujlwm sib txawv ntawm cov xim yog ua tau yooj yim: cia li hloov cov duab xim hom ntawm RGB hom lossis Hom Lab mus rau CMYK hom. Lub lag luam tshwj xeeb yog rau txim tuag Duab / Hom / CMYK. Yog li cov xim ntawm daim duab no uas muaj npe los ntawm cov xim (number case), nrog rau cov channel 4 xim. Thaum twg cov duab tso tawm, cov dots yuav raug tsim raws li cov xim channel cov ntaub ntawv, thiab muab faib ua plaub xim sib cais duab daj, magenta, cyan thiab dub.
Nyob rau hauv cov ntaub ntawv ntawm cov xim sib cais, thaum cov duab yog kis los ntawm RGB rau CMYK, qhov muag liab qab pom tau tias qee cov xim ntawm qhov screen yuav hloov yig. Yog vim li cas? Dab tsi yog qhov zoo ntawm cov xim ntawm daim duab?
A: Thaum twg daim duab hloov ntawm RGB xim hom rau CMYK xim hom, qee cov xim qaim rau ib co dluab yuav hloov obviously. Qhov kev hloov no tuaj yeem pom obviously, thiab nws yuav hloov ntawm tiag tiag li xim kom dim. Ib co xim. Qhov no yog vim hais tias cov xim gamut ntawm RGB loj dua cov xim gamut ntawm CMYK, uas txhais tau hais tias ib co xim uas tau tuaj yeem sawv cev hauv RGB xim hom muaj dhau qhov ntau xim uas CMYK tuaj yeem hais tom qab switching to CMYK. Cov xim no tsuas yog Hloov nrog cov xim zoo sib xws. Yog li cov xim no muaj ntau dua kev hloov pauv. Qhov tseeb, yog tias muaj xim hauv RGB xim hom duab dhau qhov xim gamut, koj tuaj yeem siv Gamut Ceeb toom ua ntej.
Qhov chaw gamut yog dab tsi? Lub ntsiab ntawm gamut chaw yog dab tsi?
Peb hloov cov dluab hauv RGB, CMYK, thiab Lab, qhov tseem ceeb sib txawv ua haujlwm hauv ntau qhov chaw gamut. Cov xim gamut hais txog ntau yam xim uas tuaj yeem hais tau los ntawm ib hom xim hom. Nws kuj yog hais txog ntau yam xim uas tuaj yeem hais tau los ntawm cov xov xwm tshwj xeeb xws li kev tshuaj ntsuam, cov zis tawm ntawv, thiab luam tawm. Cov xim ntawm pom spectrum nyob rau hauv qhov tsuas yog qhov loj tshaj plaws gamut qhov chaw, uas muaj tag nrho cov xim uas tib neeg qhov muag pom tau. Hauv cov xim hom, lub tshuab (lab) muaj qhov loj tshaj plaws, thiab nws muaj tag nrho cov xim hauv RGB thiab CMYK.
Dab tsi hom yog zoo dua rau qhov tsim hom xim hom duab?
A: Hauv Photoshop, daim duab hom xim muaj hom RGB, CMYK hom, GrayScale hom thiab lwm hom xim. Txhua hom tsim qhov qauv duab yog nyob ntawm qhov kawg ntawm kev tsim duab. Yog hais tias tsim duab yuav tsum luam tawm los yog sau rau ntawm daim ntawv luam tawm, nws yog qhov zoo tshaj plaws los siv CMYK xim hom kom cov xim pom ntawm qhov screen yog ze rau cov zis luam tawm xim los yog cov xim tawm. Yog tias cov qauv siv hluav taws xob (xws li web page, computer projection, video, etc.), hom xim ntawm daim duab zoo tshaj plaws los siv RGB hom, vim qhov xim ntawm RGB hom yog ntau vivid thiab richer, thiab cov daim duab zoo dua. Thiab tsuas yog 3 raws ntawm cov dluab, cov nqi ntawm cov ntaub ntawv yog me dua, thiab qhov chaw disk tseem me me. Yog tias daim duab grey, nws yog qhov zoo uas yuav siv GreyScale hom, vim tias txawm tias cov duab tau hais hauv RGB lossis CMYK xim hom, nws tseem zoo li xim grey tsis xim, tab sis nws qhov chaw disk ntau dua. Tsis tas li ntawd, yog tias daim duab gray yuav tsum luam tawm, yog hais tias nws hais hauv CMYK hom, muaj 4 cov ntaub ntawv hauv zaj duab xis thiab luam ntawv. Tus nqi tsis loj, thiab nws yuav ua rau cov xim thaw qhov teeb meem thaum lub ntsuas qhov ntsuas grey tsis zoo thaum luam ntawv. Thaum tus lej ntawm tus lej loj loj, daim duab gray yuav xim.
Yuav kub thiab nyiaj luam tawm li cas? Dab tsi yog qhov yuav tsum tau npaj rau kev npaj ua ntej?
A: Hauv kev tsim, cov neeg muas zaub feem ntau yuav tsum tau luam ntawv kub thiab nyiaj. Txij thaum kub thiab nyiaj tsis tuaj yeem pom tau los ntawm plaub-xim luam yeeb, lawv cov luam ntawv thiab kev siv tshuab muaj kev tshwj xeeb. Thaum luam ntawv, kub thiab nyiaj yog ua tiav raws li qhov chaw xim, uas yog, luam tawm nrog kub number case thiab nyiaj number case, yog li ntawd zaj yeeb yaj kiab kuj yuav tsum yog qhov chaw xim, ib zaj duab xis ib leeg, thiab luam tawm nyias.
Thaum tsim lub computer, koj yuav tsum txheeb cov xim kom sawv cev rau kub thiab nyiaj, thiab txhais cov xim raws li qhov xim nqaij kom tau raws li cov qauv tsim. Txij thaum kub, nyiaj thiab nyiaj yog opaque, kub thiab nyiaj cov ntsiab lus tau teem rau Overpint thaum tsim.
Dab tsi yog qhov nqaij xim thiab qhov muag xim xim luam ntawv? Dab tsi yog qhov nqaij xim thiab qhov muag xim xim luam ntawv?
A: Pom xim yog txhais tau hais tias thaum luam ntawv, tsis txhob luam tawm C, M, Y, K plaub xim kom coj los ua xim no, nws yog siv los luam cov xim nrog ib tus cwj mem tshwj xeeb. Hnov cov xim muaj xim ua ntej yuav tsum muaj los ntawm lub tsev luam ntawv los yog ua los ntawm lub tshuab xoom npuag. Rau txhua qhov chaw xim ntawm qhov luam tawm, nws muaj qhov tshwj xeeb xim version coj los sib sau ua ke. Siv cov xim muaj xim los ua xim ntau dua. Txawm hais tias cov xim tsis tuaj yeem sawv cev ntawm lub koos pis tawj, daim xim sau ua ntej luam ntawm cov qauv xim sib txawv yuav pom cov xim xim ntawm daim ntawv. Piv txwv, lub Pantone xim txuam system tsim ib daim qauv xim ntxaws heev. .
Rau qhov tsis yog standard tus qauv xim hauv tus tsim, lub tshuab luam ntawv tsis tas yuav yog muab faib rau nws, thiab lub xim tsis muaj peev xwm yuav tsis pom ntawm lub vijtsam, yog li tsis txhob siv koj tus kheej qhov xim tshwj xeeb yog tias nws tsis yog tshwj xeeb.
Dab tsi yog cov txheej txheem cov xim uas siv hauv computers? Txoj kev zoo tshaj los txhais cov xim txhua tus yog dab tsi?
Lus Teb: Ib qho kev xav tau los piav qhia cov xim txawv, txawm tias ntawm lub computer los sis thaum luam ntawv. Cov xim no kuj yog hu ua xim qauv lossis xim hom. Muaj ntau ntau hom qauv xim, txhua tus uas tuaj yeem piav txog cov xim ntawm cov ces kaum sib txawv, tab sis txawv xim hom yog tsim rau ntau lub sijhawm thiab qhov tseeb yog txawv.
Lub computer xim hom yog:
1, hom RGB:
Kuj hu ua RGB xim qhov chaw. Nws yog ib lub tswv yim xim uas yog siv dav hauv peb lub neej, xws li TV, computer saib, xaub, thiab lwm yam, uas siv lub teeb rau xim. Kev xa thiab luam tawm feem ntau yuav tsum xa dluab. Thawj qhov khoom scanner scans yog RGB xim cov ntaub ntawv ntawm daim duab thawj. RGB hom yog xim ntsuab ntxiv, thiab txhua yam xim muaj peev xwm yuav piav qhia los ntawm tus nqi hluav taws xob R, G, thiab B. Thaum lub computer qhia txog xim, peb yam khoom R, G, thiab B muaj ntau yam 0-255, 0 txhais tau hais tias tsis muaj nyiaj ntau, thiab 255 txhais tau hais tias muaj nyiaj ntau tshaj plaws. Thaum R, G, thiab B yog ob qho tib si 255, lub teeb dawb yog coj los ua ke, thiab thaum R, G, thiab B yog ob qho tib si, dub yog tsim. Cov hom no feem ntau yog siv thaum nthuav cov xim txhais ntawm cov lus. Dluab xws li TV, yeeb yam, network, multimedia, feem ntau siv hom RGB.
2. CMYK hom:
Kuj hu ua CMYK xim qhov chaw. CMYK yog cov tseem paub txog cov neeg nyob hauv kev lag luam luam tawm. Hom no yog hom sib txuam uas ua raws li txoj cai ntawm kev sib cais xim. Lub CMYK hom yeej tseem yog hais txog cov C, M, Y, thiab K dot qhov ntau thiab tsawg ntawm cov ntawv luam tawm thaum lub xim tawm tswv yim, yog li qhov tseem ceeb ntawm C, M, Y, thiab K li ntawm 0% mus rau 100%. CO% MO% YO% KO% indicates dawb, C100% M100% Y100% K100% indicates black.
3, HSB hom: Hawj (HUE), saturation (Saturation), ci ntsa iab (Brightness) hom.
Vim tias cov duab RGB zoo dua li cov duab CMYK, cov xim zoo nkauj dua, tuaj yeem tso cov duab RGB ncaj qha? Cov kev tshwm sim ntawm kev ua no yog dab tsi?
A: Txij thaum cov xim gamut ntawm RGB ntau dua CMYK, qee cov xim muaj nyob rau ntawm qhov screen, tab sis tsis muaj luam tawm plaub xim xim. Yog tias koj xav paub lub txim, cia li muab rau nws ib zaug. Vim qhov txawv ntawm RIP, RGB duab yuav muaj tsuas yog cov dub version ntawm cov xim sib cais zaj duab xis, lwm xim version tsis muaj duab, los yog cov ntaub ntawv ntawm plaub xim yeeb yaj duab (cov teev) yog tib yam, qhov sib npaug ntawm cov duab grey. Txawm hais tias qee qhov kev faib tshuab lossis RIP tuaj yeem hloov RGB rau CMYK, nws yog qhov zoo tshaj plaws los siv kev luam theej duab software lossis Photoshop rau hom conversion.
Tseg daim ntawv qhia xim raws li DCS daim ntawv, muaj duab thaum luam dub thiab dawb, tab sis tsis muaj duab hauv cov zaj duab xis output. Yog vim li cas?
A: Txuag daim duab raws li DCS hom ntawv yuav ua rau tsib cov ntaub ntawv.
Vim li cas ho tsis tsim qhov kev daws teeb meem hauv hom ntawv thiab graphics software?
A: Cov typesetting graphics software yog qhov khoom siv ntsees. Cov sawv cev ntawm cov ntawv nyeem thiab cov duab kos yog hais ua lus ntawm lub algorithm. Cov khoom tsim muaj ywj pheej ntawm kev daws teeb meem. Lawv tso zis rau qhov tso tawm ntawm cov khoom tso tawm. Yog tias cov twj tso zis muaj kev daws teeb meem, cov duab tso tawm ntawm nplooj ntawv tsim muaj siab. Vim li no, graphics software thiab typesetting software tsis tas yuav teev cov lus. Daim duab xa tuaj rau hauv hom ntawv thiab graphics software yuav tsum tau nyeem cov ntawv teev qhia txog cov duab qub thaum pib tawm, uas yog cuam tshuam txog kev daws teeb meem ntawm thawj daim duab.
Muaj ntau ntau hom ntawv nyob rau hauv CorelDraw?
A: CorelDraw faib cov ntawv nyeem ua ob hom, ib qho yog kos duab thiab lwm tus yog cov ntawv nyeem. Txawm hais tias ob zaj lus los yog siv cov cuab yeej cov ntawv nyeem, lawv muaj cov cwj pwm txawv, cov ntawv kos duab. Nrog ntau yam graphical object nta, koj tuaj yeem thov kev tshwj xeeb dua ntxiv rau cov ntawv kos duab; thaum lub sij hawm cov ntawv nyeem tau siv ntau hom ntawv nyeem. Raws li qhov sib txawv ntawm ob hom ntawm cov ntawv nyeem, lawv tuaj yeem siv rau lwm cov hom phiaj. Yog tias koj tsuas xav siv me me ntawm cov ntawv los yog siv ntau hom ntawv tso tawm rau cov ntawv nyeem, xws li lub npe luv thiab cov lus piav qhia, koj siv tau lo lus sau ntawv; Koj yuav tsum ua cov ntaub ntawv ntau los siv cov kev qhia ntau dua, xws li cov ntawv xov xwm, ntawv nthuav qhia, thiab lwm yam. Koj siv tau cov ntawv nyeem.
