Nws tuaj yeem siv sijhawm ntev dhau los tsim cov duab digital nrog lub scanner, tshwj xeeb yog tias koj xav tau cov txheej txheem ntau cov duab, nplooj ntawv ntawm phau ntawv, ntawv xov xwm lossis ntawv sau. Txawm li cas los xij, nws yog qhov tsim nyog yuav tau nce lub scanning ceev.
Cov Lus Qhia

Thawj qhov yuav tsum tau saib thaum tsim lub scan loj yog xim. Yog tias koj txaus siab rau cov duab dub thiab dawb, hauv lub npov scanner box, ua ntej ua cov duab, xaiv qhov nqi "dub thiab dawb" rau cov xim hom. Kev tshuaj ntsuam ob-xim hom yuav siv sij hawm tsawg dua li kev txheeb xyuas tas nrho cov xim. Qhov no feem ntau muaj tseeb thaum luam ntawv cov ntawv lossis cov ntawv rau kev luam ntawv txuas ntxiv rau ntawm daim ntawv.

Qhov thib ob uas koj tuaj yeem txuag lub sijhawm yog qhov kev daws teeb meem (DPI) ntawm daim duab kawg. Qhov qis dua tus nqi ntawm qhov ntsuas no, kev ua tiav ntawm kev ua cov duab los ntawm lub cuab yeej yuav tshwm sim. Tab sis kom tau txais cov xov tooj zoo tshaj plaws digital los ntawm kev thaij tawm, koj yuav tsum tsis txhob teeb tsa qhov kev daws teeb meem tsawg dua 300 DPI. Rau phau ntawv nplooj ntawm cov hom ntawv A5 thiab tsawg dua, ib qho kev daws teeb meem ntawm 100-200 DPI yuav muaj txaus.

Qeb peb yog kev kawm. Thaum lub scanner txheej txheem cov duab, nws siv sijhawm ntev los kuaj ua ntej. Qhov no tuaj yeem zam los ntawm tsis nias lub khawm Saib Ua Ntej tab sis nyem Luam theej duab tam sim ntawd. Qhov no yuav ua tag nrho cov chaw ua haujlwm ntawm lub ntsuas phoo, thiab tom qab ntawd kev cog qoob loo ntxiv ntawm cov duab kab ntawv yuav tsum tau yog tias qhov loj me ntawm cov duab qub tsawg dua thaj chaw ua haujlwm ntawm lub cuab yeej.

Thiab qhov kawg yog hom hom phiaj. Yog tias koj xaiv TIFF lossis BMP thaum luam tawm, cov txheej txheem hloov duab yuav siv sijhawm ntev dua li txuag cov duab tib yam li JPEG (pom zoo) lossis GIF. Cov hom ntaub ntawv tuaj yeem teev nyob rau hauv tib lub thawv ntawv uas zoo nkaus li ua ntej scanning.
