Kev cuam tshuam ntawm daim ntawv ntawm cov xim ntawm tus number case txheej yog feem ntau xav txog peb yam.
(1) Daim ntawv dawb: Daim ntawv nrog cov xim sib txawv (lossis qee yam xim) muaj qhov sib txawv ntawm cov xim ntawm cov xim luam ntawv txheej. Rau tib hom ntawv dawb board, qhov dawb yog txawv, thiab xim sib txawv ntawm cov luam ntawv number case txheej yog feem ntau pom nyob rau hauv tus naj npawb ntawm cov number case dub nyob rau hauv qhov chaw number case, tshwj xeeb tshaj yog rau cov xim ntawm brightness saum 70, qhov cuam tshuam yog tshwj xeeb tshaj yog pom tseeb, ua rau muaj qhov sib txawv loj ntawm qhov sib piv ntawm cov xim pleev xim. Yog li ntawd, nyob rau hauv qhov tseeb ntau lawm, daim ntawv nrog tib whiteness yuav tsum tau luam tawm kom deb li deb li sai tau kom txo tau cov kev cuam tshuam ntawm daim ntawv whiteness ntawm printing xim.
(2) Absorption: Thaum tib tus cwj mem luam tawm rau ntawm daim ntawv uas muaj qhov sib txawv ntawm qhov sib txawv ntawm tib yam, yuav muaj qhov sib txawv ntawm cov ntawv luam tawm. Cov qauv ntawm daim ntawv txiav txim siab tias muaj pob thiab qhov pores tsim los ntawm cov nroj tsuag fibers rau ntawm daim ntawv. Txhawm rau kom tau txais qhov zoo sib xws thiab smoothness ntawm daim ntawv, nws yog ib qho tsim nyog yuav tsum tau coated nto ntawm daim ntawv nrog coatings ntawm txawv thicknesses. Cov khoom thiab thickness ntawm txheej txiav txim siab lub peev xwm ntawm daim ntawv saum npoo kom nqus cov number case. Lub peev xwm nqus tau sib txawv yuav tsum ua kom cov xim ntawm cov xim luam ntawv txheej sib txawv. Piv nrog rau cov ntawv tsis-coated, cov xim dub txheej yuav tshwm grey thiab npub, thiab xim number case txheej yuav drift, thiab xim ntawm cyan number case thiab magenta number case yog qhov pom tseeb tshaj plaws.
(3) Gloss thiab smoothness: lub gloss ntawm daim ntawv yog nyob ntawm qhov gloss thiab smoothness ntawm daim ntawv. Qhov saum npoo ntawm daim ntawv luam ntawv yog ib qho chaw gloss, tshwj xeeb tshaj yog cov ntawv coated.
