Muaj ntau cov txheej txheem hauv kev luam ntawv. Txhawm rau kom tau txais cov ntawv luam zoo, koj yuav tsum tsis muaj teeb meem nrog txhua cov txheej txheem. Hloov siab, yog tias muaj txheej txheem uas muaj lub eeb, nws tsis tuaj yeem tau txais cov ntawv luam tawm zoo. Yog tias cov txheej txheem luam ntawv raug cais me me, muaj kev luam tawm, ua ib pawg, ua yeeb yaj kiab, pov thawj, luam ntawv, luam ntawv, thiab lwm yam.
Cov pab pawg version yog cov txheej txheem tseem ceeb rau cov duab thiab sau cov ntawv nyeem. Kev tsim cov qauv thiab kev teeb tsa ntawm pab pawg yog qhov txhais tau txiaj ntsig los xyuas kom meej thiab txhim kho kom zoo dua qub. Qhov cuam tshuam ntawm cov txheej txheem no rau kev ua tau zoo yog qhov tseem ceeb hauv:
1 Cov ntawv sau, daim duab, thaiv xim, thiab lub lag luam maj mam tsis ua qauv, uas ua rau qhov teeb tsa dhau los yog dhau xoob kom muaj kev cuam tshuam tag nrho kev zoo nkauj.
2 Vim tias qhov sib txawv ntawm kev pom ntawm qhov screen tshwm sim thiab kev daws teeb meem thiab xim hom siv nyob rau hauv kev luam ntawv tiag tiag, cov nyhuv luam ntawv tsis sib thooj nrog cov kev xav.
3 Overprinting ghosting tshwm sim nrog cov tsiaj ntawv me me lossis cov kab nyias nyias nrog cov xim sib txuam.
4 Ncaj nraim siv RGB hom pawg ua rau daim duab dub thiab dawb.
5 Rub daim duab thaum ua cov txheej txheem pab pawg ua kom daim duab tsis zoo thiab cov zis qeeb. Tshwj xeeb, kev ntxiv lub zog muaj cov txiaj ntsig zoo rau daim duab. Yog li, pawg pab pawg yuav tsum nruj me ntsis raws li cov cai ntawm kev ua haujlwm thiab kev cai. Yog tias daim duab yuav tsum ua raws li CMYK, yuav tsum hloov cov duab loj hauv Photoshop. Tsis txhob rub los yog deform, thiab daim duab, cov ntawv thaiv thiab xim thaiv qhov yuav tsum tau ua qauv; kerning ntawm cov ntawv nyeem yuav tsum tsis txhob hloov pauv, ua kom qhov chaw zoo nkauj.
Kev ua yeeb yaj kiab, tseem hu ua cov khoom tso tawm, suav nrog ntau cov txheej txheem xws li RIP kab plaub hau, cov duab thaij tawm lub ntsej muag, thiab yaug tawm thiab tshuaj ntsuam. Tswj cov txheej txheem no nrog cov ntaub ntawv thiab kev tshaj lij yog ib txoj hauv kev tseem ceeb rau kev ua kom zoo. Qhov cuam tshuam loj ntawm cov txheej txheem no rau qhov zoo yog:
1 Cov ntawv luam yog tuab thiab muaj roj vim qhov linearization ntawm cov zis zaj duab xis, cov nyhuv luam ntawv yog tsaus heev, cov duab xim tsis sib txawv thiab cov txheej txheem luam tawm tsis zoo, thiab cov xim ntawm cov xim thaiv yog deviated.
2 Vim tias qhov tshwm sim ntawm cov zaj duab xis thiab qhov tso tawm tsis raug, qhov hauv qab ntawm zaj duab xis yog qhov loj dhau thiab qhov ntom tsis txaus. Reflected nyob rau hauv kab ntawv yog lub ntsej muag qias neeg, lub teb virtual, qis-qib network tseem ceeb poob, hauv net, qhov muab tshuaj network.
3 Vim tias qib siab lossis tsawg tus ntxaij, daim duab raug puas, thiab daim duab tsis zoo.
4 Tus moiré thiab xim tshwm sim tsis zoo vim tias qhov ntsuas lub kaum ntse ntse tsis raug.
5 Lub overprinting yuam kev thiab cov kab kev cai tshwm sim tuab heev vim qhov tsawg ntawm qhov ua tiav qhov tseeb ntawm cov zaj duab xis, ua rau cuam tshuam yuam kev.
6 Cov txheej txheem sib txawv ntawm qhov tsis sib haum xeeb hauv cov qauv teeb tsa muaj qhov sib txawv.
7 Vim tias kev ua haujlwm tsis zoo xws li yaug thiab tshuaj xyuas, cov kws sau ntawv, cov ntawv luam tawm nees, thiab cov cim qias neeg tau pom ncaj qha rau cov nplaim ntawm qhov chaw khawb, qhov xav cim, thiab qhov chaw tsis huv.
Yog li ntawd, cov ntsiab lus hauv qab no yuav tsum raug sau tseg thaum lub sijhawm ua cov zaj duab xis:
1 Kev tswj cov ntaub ntawv yog lub hauv paus rau kev tswj cov txheej txheem tsim tawm ntawm zaj yeeb yaj kiab thiab lees tias qhov zoo. Cov ntaub ntawv tswj ntawm cov zis zaj duab xis muaj ob yam. Ib qho yog ua kom ntseeg tau qhov tseeb ntawm cov zis tawm, cov teev yuam kev yuav tsum tswj tsis pub dhau 2%; qhov thib ob yog cov tshauv hauv qab tom qab zaj duab xis tawm, qhov siab tshaj plaws qhov muaj txiaj ntsig ua tau raws li qhov yuav tsum tau ua, thiab hauv qab cov ntoo tshauv (D.) yuav tsum tsawg dua 0.04, qhov siab tshaj plaws Dmax ≥ 3.0. Qhov no yuav tsum muaj cov kev ntsuas ib ntu ntawm cov kev sib kis thiab cov txheej txheem yaug txheej ntawm cov zaj yeeb yaj kiab kom pom cov txheej txheem ntawm cov kab ke ntawm qhov muaj tseeb, thiab kho cov khoom sib txawv ntawm cov ntaub ntawv raw khoom txawv sijhawm. Rau cov yeeb yaj kiab sib txawv, los ntawm kev sim thiab ntau txoj kev kho kom haum, zaj duab xis ua tau raws li qhov xav tau saum toj no.
2 Kev ua haujlwm zoo thiab kev kho kom zoo. Cov haujlwm kev ua haujlwm yog ib kauj ruam tseem ceeb hauv kev ua kom muaj qhov zoo ntawm cov zis. Hauv kev tsim tawm, cov txwv ntawm txhua txheej yuav tsum zoo ib yam. Cov naj npawb ntawm cov ntxaij vab tshaus ua tau raws li cov khoom yuav tsum tau luam tawm. Lub kaum ntse ntse tsis tsim lub moiré. Qhov rov qab ua dua ntawm plaub lub phaj xim yog hauv 25μm. Txoj haujlwm, qhov loj thiab tuab ntawm tus ntoo khaub lig yog hnav zoo ib yam.
Kuv yuav ua pov thawj tom qab ua tiav qhov ua tiav zaj duab xis. Muaj ob hom pov thawj: cov ntawv pov thawj digital thiab cov ntawv pov thawj analog. Qhov zoo ntawm zaj duab xis ncaj qha txiav txim siab qhov ua pov thawj, yog li yuav ua li cas zaj yeeb yaj kiab yuav mus ua si, thiab nws muaj qhov cuam tshuam zoo rau cov ntawv pov thawj thiab luam ntawv nyob sab nraub qaum. Lub tshuab luam ntawv phaj yuav tsum them sai sai rau txoj kev xaiv ntawm lub teeb ci thiab lub sijhawm. Kev daws teeb meem nyob rau hauv lub tshuab platen yuav tsum tau ua tiav raws li qhov yuav tsum tau ua. Feem ntau, cov ntawv tuaj yeem ua tiav ua ntej, thiab tom qab ntawd cov txiaj ntsig cuam tshuam raug txiav txim siab.
