Cov yam ntxwv dav dav ntawm tus kheej-nplaum cov ntaub ntawv luam tawm yog: cov xim ci, qhov sib txawv loj, thiab pom tseeb cov nyhuv txee thaum muab tso rau hauv cov khoom. Ordinary xim prints hais txog cov txheej ntshiab, muaj zog peb-dimensional kev nkag siab, ua tiav tones, thiab nplua nuj xim. Yog li ntawd muaj ib txoj kev luam ntawv tshwj xeeb rau daim ntawv lo luam ntawv.
Cov ntawv sau tshuab luam ntawv yog tag nrho ntau tshaj plaub xim, txog li kaum ob xim luam ntawv. Kev tsim qauv ntawm daim ntawv lo yog feem ntau ua ke ntawm cov xim xim luam ntawv thiab xim xim luam ntawv thiab peb xim luam ntawv. Yog li ntawd, cov ntawv qib siab tau luam tawm ntau zaus, thiab cov ntawv sau ntawm daim teb lossis lub npe yog luam tawm hauv cov xim xim, thaum cov duab ntawm tus neeg tau luam tawm hauv plaub-xim mesh suab. Txawm hais tias cov xim zoo ib yam, cov khoom siv thiab cov khoom siv mesh tau luam tawm ob zaug kom ua tiav qhov pom kev zoo tshaj plaws.
Cov xim luam tawm feem ntau yog luam tawm plaub xim ntawm cov tshuab luam ntawv offset. Cov tshuab luam ntawv siv yog ib qho, ob-xim thiab plaub-xim offset presses. Yog tias daim ntawv lo luam tawm nrog kev luam ntawv offset, cov khoom xim blocks, kab thiab cov ntawv ntawm daim ntawv lo tau luam tawm ua ke nrog kev ua kom tiav ntawm qhov layout. Vim qhov kev txwv ntawm offset luam ntawv yam ntxwv, tus cwj mem xim thiab lub siab ntawm txhua qhov yog zoo ib yam, yog li nws tsis yooj yim rau kev cuam tshuam cov yam ntxwv ntawm daim ntawv lo rau ntawm daim ntawv tiav. Feem ntau, qhov chaw xim ntawm lub tshuab luam ntawv offset yog ua los ntawm lub tshuab luam ntawv tiaj tus, thaum lub tshuab luam ntawv daim ntawv lo xim.
Nws yog luam tawm los ntawm cov xim xim xim, thiab cov nyhuv ntawm ob qhov sib txawv.
Cov txheej txheem ntawm daim ntawv lo luam ntawv yog tsim raws li cov yam ntxwv ntawm daim ntawv lo, thiab lub tshuab luam ntawv daim ntawv lo tseem tsim los rau cov ntawv luam tawm, uas yog cov khoom siv tshwj xeeb. Txawm hais tias lub tshuab luam ntawv zoo tib yam tuaj yeem luam tawm cov ntawv luam tawm zoo, nws muaj qee qhov kev txwv rau cov ntawv luam ntawv qib siab, yog li tam sim no, cov ntawv qib siab tus kheej nplaum tau luam tawm los ntawm ntau dua rau lub tshuab luam ntawv xim.
