Yuav ua li cas kom ua tau zoo - luam ntawv zoo

High-cov ntawv xov xwm zoo yuav tsum muaj cov duab ci ntsa iab, tag nrho cov xim ntawm cov cim Suav, thiab cov kab mob stroke meej, thiab tag nrho cov tsos mob yuav tsum txaus siab rau lub qhov muag. Yuav kom ua tiav lub hom phiaj no, nws yog ib qho nyuaj rau kev cia siab rau lub tuam txhab luam ntawv ib leeg, thiab tag nrho cov txheej txheem tswj yuav tsum tau ntxiv dag zog rau cov ntawv xov xwm uas ua tau raws li qhov yuav tsum tau ua. Cov ntsiab lus tswj tshwj xeeb yog raws li hauv qab no.

Tsim cov ntawv txuas

Kev sau ntawv xov xwm feem ntau yog ua los ntawm cov kws sau ntawv sau ntawv, thiab chav luam ntawv tau txais feem ntau tsis yog - cov ntaub ntawv kho tau uas tau hloov mus rau PS hom lossis hom PDF. Vim hais tias cov neeg kho cov ntawv sau tau paub zoo hauv cov kev qhia tshwj xeeb, lawv yuav tsis tas yuav nkag siab cov ntsiab lus ntawm kev luam ntawv, yog li cov ntaub ntawv tsim tawm yuav tsis ua raws li cov cai ntawm kev luam ntawv. Lub tuam tsev editorial ntseeg hais tias tus tsim thiab kev npaj ntawm exquisite heev tshwj xeeb cov teebmeem, tab sis cov nyhuv tom qab luam ntawv yog deviated los ntawm kev cia siab, thiab qhov teeb meem no feem ntau tsis tshwm sim los ntawm lub lag luam ntawm lub printing unit, tab sis qhov teeb meem nyob rau hauv lub typesetting tsim link.

Piv txwv li, nyob rau hauv cov nqe lus ntawm cov xim, kho cov neeg ua hauj lwm feem ntau siv RGB hom thaum ua dluab nyob rau hauv computers, uas muaj ib tug dav xim gamut thiab vivid xim. Txawm li cas los xij, cov txheej txheem luam ntawv txais yuav hom CMYK thoob ntiaj teb, thiab cov xim gamut tsis dav li RGB hom. RGB hom dluab yuav tsum tau hloov dua siab tshiab rau CMYK hom ua ntej luam ntawv, thiab xim gamut compression yuav ua rau cov xim ntawm cov khoom luam tawm tsis tshua muaj tiag tiag li ntawm cov ntaub ntawv hluav taws xob, uas yog ib txwm tshwm sim thiab tsis muaj teeb meem luam tawm. Raws li cov yam ntxwv ntawm cov txheej txheem luam ntawv, lub tuam tsev kho mob yuav tsum tsom mus rau cov teeb meem hauv qab no:

(1) Ua tib zoo saib rau kev hloov xim hom. Thaum ntaus ntawv, tag nrho cov duab yuav tsum tau hloov mus rau CMYK hom kom tsis txhob muaj cov ntaub ntawv poob los ntawm kev yuam kom hloov xim hom los ntawm cov neeg ua haujlwm luam ntawv.

(2) Tswj qhov gradation ntawm daim duab thiab tag nrho cov number case. Thaum ua cov duab, nws yog ib qho tsim nyog yuav tsum qhib qhov sib piv ntawm daim duab, kom qhov gradation ntawm txhua qib sib npaug sib npaug, thiab zam kom tsis txhob daim duab ci dhau los lossis tsaus nti. Daim duab xim yuav tsum xyuas kom meej tias tag nrho cov ntsiab lus ntawm tus number case overprint yog tsawg dua 260%. Cov duab nrog cov xim dub uas yog xim tseem ceeb yuav tsum tau hloov mus rau grey tones, thiab tsis txhob siv plaub - xim hluavtaws dub, kom tsis txhob ua kom qeeb qeeb kom qhuav ceev ntawm tus number case thaum lub sij hawm luam ntawv vim yog number case tsub zuj zuj, ua rau rub thiab rub.

(3) Tsim nyog ua cov duab. Nyob rau hauv cov txheej txheem ntawm cov duab luam ntawv, yog tias qhov kev faib ua feem ntawm daim hlau xiav thiab dub yog qhov loj, cov nyhuv luam ntawv yuav ua rau muaj kev phem ntau dua li qhov pom ntawm lub computer screen. Qhov teeb meem no feem ntau yog vim qhov tsaus ntuj ntawm xiav thiab dub inks thiab nthuav cov dots. Cov xim ntawm cov xim xiav thiab dub yog tsaus dhau, uas yuav ua rau qhov kev faib ua feem ntawm qhov tsaus ntuj ntawm daim duab nce, thiab qib duab tsis meej, ua rau nws yooj yim rau paste version. Yog li ntawd, thaum ua cov duab, yog tias cov xim xiav thiab dub daim hlau loj dhau lawm, nws yuav tsum raug txo kom tsim nyog (nws pom zoo kom txo nws li 15%).

(4) Ua tib zoo saib xyuas qhov chaw ntawm daim duab. Thaum typography, tsis txhob npaj cov duab nrog cov suab sib txawv loj thiab cov qauv hauv tib qhov chaw sib xyaw ua ke tib lub sijhawm. Thaum lub sij hawm luam ntawv, tus naj npawb ntawm tus number case nyob rau hauv tib txoj hauj lwm yog tswj los ntawm tib txheej ntawm tus number case yuam sij. Yog hais tias ob daim duab nrog cov xim sib txawv muaj zog nyob rau hauv tib txheej txheej ntawm tus number case, nws yog ib qho nyuaj rau coj mus rau hauv tus account cov xim luam tawm ntawm cov duab sib txawv ntawm tib lub sijhawm.

(5) Tsim nyog npaj cov xim blocks. Cov kab lus teb lossis cov xim loj hauv cheeb tsam feem ntau yog siv hauv kev kho thiab kev sau ntawv txhawm rau txhim kho qhov pom kev pom, tab sis cov qauv zoo li no muaj feem cuam tshuam, tawg paj thiab sib tsoo thaum luam ntawv. Yog li, nws raug pom zoo kom siv ntau tshaj 90% sib sib zog nqus lub vev xaib los hloov cov qauv tsim, thiab txhim kho cov nyhuv luam ntawv los ntawm kev teeb tsa cov xim ntom ntom kom zoo.

(6) Optimize shading tsim ntawm daim duab. Yog tias cov qauv shading ntawm daim duab yog ze rau cov xim tom qab, cov shading yuav tsis pom tseeb lossis tsis paub tom qab luam ntawv, vim tias cov xim tom qab tsaus dhau, ua rau nws nyuaj rau nthuav tawm cov duab ntxoov ntxoo.

(7) Tsis txhob overprinting teeb meem nyob rau hauv cov ntawv nyeem. Raws li kev lag luam cov qauv, qhov yuam kev overprinting ntawm ob xim ntawm cov ntawv xov xwm xim yuav tsum tsawg dua 0.15mm. Qhov no yog vim qhov tseeb tias muaj qee qhov nro ntawm cov ntawv xov xwm, thiab kev hloov pauv me ntsis thaum lub sijhawm luam ntawv yuav ua rau muaj kev sib txawv ntawm cov ntawv luam tawm, yog li kev siv plaub - xim ntawv yuav tsum raug txo kom tsawg, thiab nws yog qhov zoo tshaj plaws los siv cov ntawv monochrome kom tsis txhob muaj teeb meem overprinting uas ua rau cov ntawv tsis meej.

(8) Xaiv hom font kom tsim nyog. Lub cev ntawm cov ntawv xov xwm yog qhov zoo tshaj plaws los siv Bao Song font, thiab qee cov neeg kho xaiv xaiv lwm cov fonts rau kev nrhiav tus cwj pwm, uas zoo nkauj thaum tso tawm ntawm qhov screen, tab sis thaum lub sij hawm luam ntawv, lawv raug cuam tshuam los ntawm kev nthuav dav ntawm cov dots thiab tsub zuj zuj ntawm tus number case, thiab muaj teeb meem xws li "tawg khawb" thiab "pasted plates". Qhov no yog vim muaj zog ntawm tus number case absorption thiab siab roughness ntawm cov ntawv xov xwm, uas yuav ua rau cov font strokes ua thicker los yog pasted ua ke, thaum cov qauv ntawm Baosong font strokes yog yooj yim, kab rov tav thiab nyias thiab ntsug, uas tuaj yeem hloov mus rau cov yam ntxwv ntawm cov ntawv xov xwm, zoo tiv thaiv qhov tsis sib xws ntawm tus cwj mem los ntawm cov ntawv fibers, thiab txo qhov loj me ntawm luam ntawv.

Kev ua phaj

Tam sim no, computer direct phaj ua (CTP) tshuab tau dav siv nyob rau hauv cov ntawv xov xwm phaj ua, thiab cov tsoos zaj duab xis tso zis thiab phaj ziab txheej txheem tau raug tshem tawm. CTP phaj ua muaj qhov zoo ntawm cov zis ceev ceev, siab raug, me me network deformation, ruaj khov zoo, thiab kev txuag cov neeg ua haujlwm, tab sis nws muaj cov kev xav tau siab rau cov neeg ua haujlwm, thiab nws yuav tsum muaj nyob rau hauv - qhov tob ntawm cov txheej txheem imposition thiab kho vajtse kev paub, cov kev cai tshwj xeeb yog raws li hauv qab no:

(1) Ua haujlwm zoo hauv cov txheej txheem docking. Lub phaj ua txuas yog lub qhov rais ncaj qha txuas nrog lub tuam tsev kho mob, thiab yog tias muaj teeb meem, kev luam ntawv yuav tsis ua haujlwm. Yog li ntawd, tus tsim phaj yuav tsum paub ua ntej cov software siv los ntawm lub tuam tsev kho mob rau kev sau ntawv, hom tsev qiv ntawv font thiab cov ntaub ntawv tsim tawm. Yog tias muaj cov txheej txheem tsis sib xws, qhov tseem ceeb yuav tsum tau muab rau kev sib koom tes, hloov cov software tsim khoom lossis cov tsev qiv ntawv font, txo tus nqi poob, thiab zam kev poob loj los ntawm kev hloov cov phaj.

(2) Ua haujlwm zoo hauv CTP cov cuab yeej tu. Vim muaj plua plav lossis lwm cov khoom raug tshem tawm thiab lwm cov pa phem hauv ib puag ncig, tom qab siv cov cuab yeej siv rau lub sijhawm, txoj kev kho qhov muag sab nraud thiab txoj hauv kev kho qhov muag ntawm lub laser tej zaum yuav daig nrog cov plua plav, ua rau poob ntawm lub laser thaum lub sijhawm ua haujlwm ntawm txoj kev kho qhov muag, ua rau cov zis dots rau deform lossis shrinkage, uas ua rau cov duab me me ntawm qhov loj me thiab qhov loj me ntawm cov hlab ntsha tawg. poob los yog deformed. Yog li ntawd, txoj kev laser lub teeb yuav tsum tau ntxuav tsis tu ncua thiab laser waveform calibrated.

(3) Ua ib txoj haujlwm zoo nyob rau hauv linearization nkhaus ntawm lub phaj. Nyob rau hauv tus txheej txheem ntawm CTP phaj ua, vim qhov kev hloov ntawm lub hom, ntau lawm batch thiab lwm yam kev mob ntawm phaj ua, phaj txiag yuav tsum tsis tu ncua linearize tag nrho cov txheej txheem ntau lawm los xyuas kom meej tias cov zis graphic cov ntaub ntawv yog ncaj ncees rau tus thawj thiab tsis txhob cov ntaub ntawv poob los yog distortion.

(4) Tswj cov xwm txheej ntawm kev tsim thiab luam ntawv txheej txheem. Tam sim no, tsis muaj -rinse version tau siv dav, tab sis cov txheej txheem ntawm potion txoj kev loj hlob thiab phaj luam ntawv tseem muaj. Rau yav tom ntej, lub phaj txiag yuav tsum tsim nyog tswj qhov kub thiab txias ntawm cov txheej txheem tsim tawm, thiab npaj cov txheej txheej ntawm cov nplaum tiv thaiv kom ntseeg tau qhov zoo ntawm cov ntawv luam ntawv. Yog tias CTP phaj tsis tau tsim tag nrho, qhov khoob ntawm lub phaj luam ntawv yuav nyob twj ywm nrog cov txheej txheem oleophilic, thiab cov ntawv xov xwm yuav qias neeg thaum luam ntawv ntawm lub tshuab; Yog tias cov nplaum nplaum tiv thaiv tsis sib npaug, lub phaj dawb yuav raug oxidized ib nrab, hydrophilicity yuav tsis muaj zog, thiab tus number case yuav stains thaum luam ntawv ntawm lub tshuab, ua rau cov phaj qias neeg, yog li nws yuav tsum tau tiv thaiv.

Kev luam ntawv txuas

Cov khoom siv luam ntawv xov xwm feem ntau yog raws li cov tshuab ua teb, nrog rau kev luam ntawv ceev ceev thiab cov cwj pwm luv luv, siv cov kua dej txias -solidifying number case, siv hom kev ziab kom qhuav, thiab luam tawm los ntawm cov roj hmab chais kom ua tiav kev sib nrig sib embossing. Cov txheej txheem ntawm kev hloov tus number case los ntawm lub phaj rau lub substrate muaj xws li luam ntawv phaj, inks, ntub dej, pam vov, ntawv thiab lwm yam ntaub ntawv luam ntawv, raws li zoo raws li tus number case conveying ntaus ntawv, dej conveying ntaus ntawv thiab luam ntawv roller ntawm lub tshuab luam ntawv. Vim yog qhov ceev ceev luam ntawv ceev thiab lub sij hawm luv luv number case, kev luam ntawv tsim nyog thiab kev sib koom ua ke ntawm cov ntaub ntawv no ncaj qha cuam tshuam rau kev luam ntawv zoo, thiab tsib hom teeb meem hauv qab no yuav tshwm sim:

(1) Cov txheej txheem yog qias neeg.
