Thaum tus neeg ua lag luam luam ntawv ua tib zoo xyuas cov xim xim luam tawm los ntawm lub tshuab luam ntawv, nws pom tias yuav muaj lub chromatism ntawm tus qauv luam tawm los ntawm cov ntawv luam ntawv hauv flatbed thiab cov nyhuv cov xim. Qhov kawg yuav raug muab luam tawm. Txwv tsis pub, qhov poob yog tsis yog khoom, lub sijhawm, kev koom tes, cov qhua tuaj yeem kuj yuav ploj mus, yam ua rau nws?
1. Duab teeb meem: ua ntej tus neeg teb xov tooj siv cov tshuab luam ntawv los luam tawm, yuav tsum tau ua ib co kev kho mob ntawm tus qauv kom txog rau thaum cov nyhav tiav cov neeg yuav tsum tau ua, ces pib sau. Ua ntej luam tawm, nws yog qhov zoo tshaj plaws los ua ib qho kev sim ua qauv txog thaum uas qhov kev xav tau tshwm sim.
2. Nwg qhov teeb meem: tus number case yog qhov tseem ceeb ntawm qhov kawg luam tawm cov nyhuv, yog tias tus ntaiv ntawv tus qauv luam ntawv zoo li tus neeg pluag tsis zoo, nws tsis yooj yim luam tawm cov khoom uas tus neeg xav tau.
3.
