“Koj puas totaub txog kev ntim khoom?
Cov lus teb tsis yog qhov tseem ceeb tshaj plaws, cov txiaj ntsig tau zoo yog qhov muaj txiaj ntsig ntawm kab lus no. Los ntawm kev tsim qauv mus rau kev siv cov khoom ntim, nws yog feem ntau yooj yim rau kev saib xyuas cov ntsiab lus ua ntej luam ntawv. Tshwj xeeb tshaj yog cov neeg tsim khoom ntim, uas tsuas muaj kev nkag siab zoo ntawm kev luam ntawv, ib txwm ua zoo li "cov neeg sab nrauv". Txhawm rau ntxiv dag zog rau kev sib txuas lus ntawm cov neeg tsim khoom ntim khoom thiab cov chaw luam ntawv, hnub no kuv yuav qhia koj txog cov ntsiab lus uas yooj yim rau kev saib ua ntej luam ntawv!
Luam ntawv dots
Vim li cas peb thiaj xav tau dots?
Dots tam sim no yog txoj hauv kev zoo tshaj plaws thiab siv tau los qhia qhov kev sib tw ntawm cov xim dub thiab dawb. Txwv tsis pub, ntau pua qhov sib txawv grayscale inks yuav tsum tau kho ua ntej rau kev luam ntawv. Tus nqi, sijhawm thiab thev naus laus zis yog txhua yam teeb meem. Kev luam ntawv yeej tseem yog xoom thiab ib lub tswv yim.
Qhov ceev ntawm cov dot faib yog txawv, yog li cov xim luam tawm yuav txawv.
Preflight
Preflight checks kom paub meej tias qhov tseeb ntawm nplooj ntawv piav qhia cov ntaub ntawv; tus txheej txheem daim pib ua haujlwm lees txais nplooj ntawv piav qhia cov ntaub ntawv uas yuav nkag mus rau cov txheej txheem, thiab tom qab ntawd ua haujlwm pib ua haujlwm ntawm daim pib ua haujlwm; Cov kauj ruam tom ntej yog teeb tsa qhov sib txawv, hloov cov duab, kev tso cai, kev sib cais xim, kev tswj xim thiab cov khoom tso tawm, thiab cov txiaj ntsig tau tshwm sim hauv daim pib ua haujlwm.
DPI daws teeb meem
Thaum nws los txog rau kev daws teeb meem, peb pab tsis tau tab sis hais txog "vector graphics" thiab "bitmap".
Cov duab vector:graphics tsis distorted thaum loj los yog txo
Bitmap:DPI-tus naj npawb ntawm pixels muaj nyob rau hauv txhua nti
Feem ntau, cov duab tso tawm ntawm peb lub vijtsam yog 72dpi lossis 96dpi, thiab cov duab hauv cov ntawv luam tawm yuav tsum tau ua kom tau raws li 300dpi +, thiab cov duab yuav tsum tau muab tso rau hauv Ai software.
Xim hom
Cov ntaub ntawv luam tawm yuav tsum nyob hauv hom CMYK. Yog tias nws tsis tau hloov dua siab tshiab rau CMYK, nws muaj feem ntau tias cov qauv tsim yuav tsis raug luam tawm, uas yog qhov peb feem ntau hu ua qhov teeb meem xim sib txawv. CMYK xim feem ntau tsaus dua li xim RGB.
Font loj thiab kab
Feem ntau muaj ob txoj hauv kev los piav qhia qhov loj me, uas yog tus lej system thiab qhov system taw tes.
Nyob rau hauv tus lej system, yim-point font yog qhov tsawg tshaj plaws.
Hauv qhov system taw tes, 1 phaus ≈ 0.35mm, thiab 6pt yog qhov tsawg tshaj plaws font loj uas tuaj yeem nyeem tau ib txwm. Yog li ntawd, qhov tsawg kawg nkaus font loj rau luam ntawv feem ntau yog teem rau 6pt
(Qhov tsawg kawg nkaus font loj rauHongze Ntimtuaj yeem teem rau 4pt)
Cov kab luam ntawv, 0.1pt yam tsawg kawg nkaus.
Font conversion/contouring
Feem ntau, ob peb lub tsev luam ntawv tuaj yeem nruab tag nrho cov ntawv Suav thiab Askiv. Yog tias lub tsev luam ntawv lub computer tsis muaj font no, cov font yuav tsis tso tawm ib txwm. Yog li ntawd, lub font yuav tsum tau hloov mus rau nkhaus nyob rau hauv lub ntim tsim cov ntaub ntawv.
Ntshav
Los ntshav yog hais txog tus qauv uas ua rau cov khoom loj tuaj ntxiv thiab ntxiv qee cov qauv txuas ntxiv ntawm txoj haujlwm txiav. Nws yog tshwj xeeb yog siv rau txhua tus txheej txheem ntau lawm nyob rau hauv nws cov txheej txheem kam rau ua kom tsis txhob dawb npoo los yog txiav cov ntsiab lus ntawm cov khoom tiav tom qab txiav.
Kev luam tawm
Kuj tseem hu ua embossing, nws txhais tau hais tias ib qho xim luam tawm rau sab saum toj ntawm lwm cov xim, thiab tus cwj mem yuav sib xyaw tom qab luam tawm.
Cov xim ntau tshaj yog xim dub, thiab lwm yam xim feem ntau tsis overprinted.
Kev luam tawm
Tsis txhob sib tov ntawm inks. Feem ntau thaum ob yam khoom sib tshooj, cov xim luam tawm tom qab yog hollowed tawm ntawm qhov sib tshooj kom cov inks sab sauv thiab qis tsis sib xyaw.
Qhov zoo: Kev tsim cov xim zoo nkauj
Disadvantages: Tej zaum yuav tsis overprint kom raug, nrog dawb me ntsis (daim ntawv xim)
Nrauj yog ib tug hloov version ntawm overprinting. Los ntawm kev nthuav dav ntawm ntug ntawm ib qho khoom, cov xim ntug yuav sib xyaw nrog cov xim dhau los. Lub overprinting yuav tsis qhia cov npoo dawb txawm tias nws yog offset. Ntug feem ntau yog loj los ntawm 0.1-0.2mm.
Imposing
Xim txawv
Cov xim txawv li cas?
Cov xim ntawm cov khoom luam tawm yog cuam tshuam los ntawm cov yam ntxwv xws li xim hom, lub cev lub zog ntawm cov substrates, cov txheej txheem ntawm lub tshuab tsis, ink mixing master experience, light, etc. Cov yam ntxwv no txawv, yog li cov xim sib txawv yuav tshwm sim.
Hauv kev luam ntawv, muaj ntau yam xim uas feem ntau hu ua xim txaus ntshai. Cov khoom luam tawm muaj qhov sib txawv ntawm cov xim, yog li nws feem ntau tsis pom zoo kom siv cov xim no rau kev luam ntawv. Nws yog qhov zoo dua los siv cov xim tsis tu ncua.
Cia peb saib cov zaub ntawm cov "xim txaus ntshai" hauv 10% xim ntau:
xim txiv kab ntxwv
Navy xiav
Ntshav
Xim av
Plaub xim grey
Plaub xim dub
Ib qho xim dub C0M0Y0K100, nws yooj yim heev los hloov lub phaj luam ntawv, tsuas yog ib lub phaj yuav tsum tau hloov.
Plaub-xim dub C100 M 100 Y100 K100, nws tsis yooj yim heev los hloov lub phaj, nws yog ib qho yooj yim kom muaj xim cam los yog sau npe tsis raug. Yog li ntawd, feem ntau tsis pom zoo kom siv plaub-xim dub, thiab feem ntau cov tshuab luam ntawv tsis luam plaub-xim dub.
