Yuav ua li cas txhawm rau luam ntawv zoo ntawm cov ntawv xov xwm xim ua ntej Daim Npav Hnub Yug Zoo tau luam tawm

Yuav ua li cas txhawm rau luam ntawv zoo ntawm cov ntawv xov xwm xim ua ntej Daim Npav Hnub Yug Zoo tau luam tawm

 

Tam sim no, cov ntawv xov xwm luam ntawv nyiam nyiam cov neeg nyeem thiab cov neeg tshaj tawm nrog cov xim, yog li cov xim luam ntawv ib leeg thiab ob sab xim luam ntawv tau dav siv. Yuav sau cov xim zoo li cas hauv ntawv xov xwm? Ntxiv rau kev daws cov teeb meem ntawm daim ntawv, number case thiab luam ntawv xovxwm, kev ua digital ntawm cov duab prepress yog qhov tseem ceeb.

 

Cov ntawv xov xwm luam tawm txawv ntawm kev lag luam luam ntawv, ntawv xov xwm luam ntawv substrate rau cov ntawv xov xwm, kev siv cov tshuab luam ntawv xov xwm ceev ceev, kev nthuav dav ntawm lub network thiab kev nthuav dav ntawm daim ntawv yog qhov tseem ceeb sib txawv ntawm kev lag luam luam ntawv, yog li nyob rau hauv cov duab pem hauv ntej thiab typeetting. , kho kom tau raws li cov kev cai luam ntawv.

 

1. Daim duab kho cov xim hom

Yuav kom rov qab tau cov xim tseeb thiab nplua nuj txheej ntawm cov duab kom ntau li ntau tau, cov duab xim yuav tsum tau kho hauv RGB xim hom. Thaum ua haujlwm nrog cov duab hauv Photoshop, hom RGB zoo dua li CMYK hom. Nws tau ua tiav hauv hom RGB thiab tom qab ntawd hloov mus rau hom CMYK. Thaum luam theej duab hauv Photoshop, tsuas yog xaiv RGB Chaw xaiv hauv xim xaiv xaiv, thiab cov duab xim nkag los ntawm lub scanner yog nyob rau hauv RGB hom. Vim tias cov xim gamut ntawm RGB hom muaj ntau dua li ntawm CMYK hom, cov ntaub ntawv xim tuaj yeem cuam tshuam tag nrho, thiab cov duab ua hauv RGB hom yuav tau txais qhov chaw xim dav dua thiab ntau qhov kev ua haujlwm sib txawv.

 

2. Kev kho ntawm articulation

Kev luam tawm ntawm cov ntawv xov xwm txiav txim siab tias tus naj npawb ntawm cov hlua khi hauv cov duab ntawm cov ntawv xov xwm xim tsis tuaj yeem siab dhau, feem ntau yog li 90 kab rau 110 kab, yog li cov duab hloov kho yuav tsum tau ua kom pom tseeb kom pom tseeb ntawm daim duab. Lub sharpening degree muaj feem xyuam rau hom thiab zoom piv ntawm thawj daim duab. Feem ntau, lub sharpening degree ntawm daim duab daim duab yog tsawg, thaum lub toj roob hauv pes duab yog loj. Cov duab loj dua, qhov ntau dua qhov sharpening degree; Qhov siab dua qhov magnification, qhov tob dua qhov sharpening.

 

3. Kev hloov kho hierarchical

Lub hom phiaj ntawm kev hloov qib yog thawj zaug kom tau raws li cov kev cai luam ntawv, raws li cov yam ntxwv ntawm cov ntawv xov xwm luam ntawv dot nce tus nqi, kom them nyiaj rau qhov nce ntawm cov dot, lub ntsiab theem yog concentrated nyob rau hauv nruab nrab cheeb tsam, uas yog, 20% rau 60% ntawm qhov muag pom qhov muag pom, kom lub suab ntawm cov ntawv sau qub mus rau qhov siab tshaj plaws thiab cov ntawv luam tawm tuaj yeem tsim cov suab nrov raws li qhov kev txiav txim, kom cov duab meej thiab tiag. Thib ob, raws li cov ntsiab lus ntawm cov ntawv sau qub thiab kev faib tawm ntawm qib, kom ntseeg tau tias qhov tseeb ntawm qhov tseem ceeb ntawm qib, xws li lub ntsej muag ntawm tus cwj pwm yuav tsum yog qhov tseeb, kho tus nqi ntawm lub teeb siab heev lossis tsaus nti, tsis yog thaj tsam loj ntawm lub vas.

 

4. Hom hloov dua siab tshiab

Hom duab siv rau kev luam ntawv yuav tsum yog hom CMYK. Ua tib zoo saib xyuas cov xim sib cais Chaw hauv cov duab ua software, thiab teeb tsa qhov ntsuas no yog qhov tseem ceeb kom tau txais cov xim luam ntawv tsim nyog. Cov dot nce yog li 30%, tag nrho tus lej number case yog 220% ~ 260%, kev siv GCR, cov xim dub yog nruab nrab, cov xim dub pib ntau dua 30%, thiab qhov siab tshaj plaws ntawm cov xim dub yog 85 %.

 

5. Resize ib daim duab

Nyob rau hauv cov txheej txheem ntawm cov pab pawg neeg, tsis txhob loj los yog shrink cov duab ntawm lub siab nyiam nyob rau hauv pab pawg neeg software, yog li ntawd ntau cov duab cov ntaub ntawv yuav ploj, ua rau cov duab luam tawm tsis muaj zog los yog tsaus thiab kho. Yog tias koj yuav tsum hloov cov duab loj, koj yuav tsum rov qab mus rau cov duab ua software rau kev kho. Qhov no tuaj yeem ua kom qhov khaws cia ntawm cov ntaub ntawv duab.

 

6. Kev ua font me me

Cov ntawv xov xwm luam ntawv nrawm nrawm, qhov taw qhia nthuav dav yog qhov loj, tsis muaj kev lag luam luam tawm kom siab tshaj qhov tseeb, yog tias siv ntau xim me me hauv cov qauv tsim yog yooj yim los tsim cov font vim tsis pub luam tawm. ua rau lub font plooj thiab ob npaug, tib yam yuav tsum tsis txhob siv nyob rau hauv ntau xim overprinting duab ntawm dawb me me font. [tom ntej]

 

7. Pab pawg phaj layout xim

Tsom ntsoov rau cov xim ci.

Cov ntawv xov xwm tsis muaj txheej, muaj xim tom qab, ci tones pab muab lub teeb pom kev kaj. Cov xim yuav tsum saturated. Cov ntawv xov xwm yog ntxhib, luam ntawv nrog ntxhib mesh, saturated tones yog qhov muag ntau dua.

 

Tam sim no ntau cov ntawv xov xwm tau yuav cov ntawv pov thawj digital, cov kab ke no feem ntau siv thoob ntiaj teb ICC txoj kev kho xim, xim hloov pauv tag nrho coj mus rau hauv tus account xim gamut ntawm cov ntawv xov xwm luam ntawv, ua ke nrog cov yam ntxwv ntawm cov ntawv xov xwm luam ntawv, kom ntseeg tau tias xim, theem ntawm kev nthuav dav, lub teeb thiab tsaus qhov sib piv ntawm cov qauv luam tawm xim thiab cov ntawv xov xwm luam tawm kawg yog qhov zoo ib yam. Tom qab kho cov duab pab pawg, qhov kev tshawb pom no tuaj yeem siv los txhim kho cov duab zoo thiab cov pab pawg ntawm cov ntawv xov xwm tag nrho, tshwj xeeb tshaj yog cov nyhuv luam tawm ntawm cov duab tshaj tawm tuaj yeem kwv yees.

 

Tau kawg, platemaking kuj yog ib qho tseem ceeb cuam tshuam rau qhov zoo ntawm cov ntawv xov xwm luam ntawv. Tam sim no cov ntawv xov xwm phaj ua feem ntau muab faib ua ob txheej txheem. Ib tug phototypesetter tso zis zaj duab xis thiab ces luam PS version. Siv cov txheej txheem no, peb yuav tsum nruj me ntsis tswj ntau cov ntaub ntawv tseem ceeb, thaj chaw ceev ntawm cov xim sib cais yuav tsum siab dua 3.2, grey pos huab degree ntawm substrate (xws li lub superposition ntawm ntau txheej substrate) yuav tsum tsawg dua {{3. }}.15, thiab qhov yuam kev linear ntawm cov xim sib cais yuav tsum yog ntxiv lossis rho tawm 1%.

 

Txhawm rau kom ntseeg tau tias cov yeeb yaj kiab tso tawm tau zoo, txhua zaus koj hloov lub yob tshiab ntawm cov yeeb yaj kiab lossis hloov kho tus tsim tawm, RIP software yuav tsum yog curvilinear kom ntseeg tau tias cov ntaub ntawv thiab cov yeeb yaj kiab tso tawm tuaj yeem ua tau zoo ib yam. Kev tu lub tshuab tsis tu ncua, tshwj xeeb tshaj yog lub tshuab zaj duab xis, kuj tseem ceeb heev. Kev luam ntawv tuaj yeem muab ntxiv rau hauv cov ntaub ntawv bar, siv los ntxiv dag zog rau kev ruaj ntseg ntawm cov ntawv txuas.

 

Lwm cov txheej txheem yog ncaj qha computer phaj ua. Nws tawg los ntawm cov kev txwv ntawm cov txheej txheem ntawm cov phaj ua cov txheej txheem tso tawm zaj duab xis los ntawm laser phototypesetting thiab phau ntawv luam tawm thiab luam ntawv, thiab zam cov paj, dot variations, dot inconsistencies tshwm sim los ntawm qhov sib txawv ntawm lub phaj raug lub sij hawm nyob rau hauv cov txheej txheem luam ntawv thiab qhov yuam kev thiab yuam kev los ntawm phau ntawv sau ntawv thiab luam ntawv.

 

Cov ntawv xov xwm xim xav tau ntau dua qhov tseeb tshaj, ua phaj sai dua, lub sijhawm luam ntawv luv dua, thiab cov ntawv xov xwm ntev dua. Yog li ntawd, lub tshuab yog nrov heev nyob rau hauv ntau yam ntawv xov xwm, thiab cov tsis paub meej yam ntawm no phaj ua txheej txheem yog ob peb, thiab cov ntaub ntawv thiab standardization yog tiag tiag paub nyob rau hauv lub phaj ua txheej txheem.

 

Nyob rau hauv cov txheej txheem ntau lawm, peb yuav tsum tau them sai sai rau cov linear tso zis ntawm lub tshuab platemaking, xyuas kom meej tias qhov tso zis dot feem pua, thiab tswj kom raug qhov kub thiab txias thiab ntxiv ntawm cov kua stamping. Direct platemaking system yog tag nrho cov kev lag luam digital platemaking txheej txheem tsim los ntawm digital workflow, ncaj qha platemaking tshuab, digital proofing, tsis siv neeg phaj dabtsi yog khoov thiab xuas nrig ntaus tshuab. Kev taw qhia txog cov txheej txheem no tau ua lub luag haujlwm hauv kev txhawb nqa cov txheej txheem zoo thiab cov ntaub ntawv tswj hwm ntawm cov ntawv xov xwm luam ntawv.

Nyob rau hauv luv luv, los xyuas kom meej qhov zoo ntawm cov ntawv xov xwm luam ntawv, pib los ntawm qhov zoo ntawm cov thawj daim duab, los xyuas kom meej qhov zoo ntawm cov phaj ua, los ntawm kev ua ntej-kawg mus rau qhov kawg printing kom tiav cov ntaub ntawv thiab standardization.
