Kev ua haujlwm rau cov tshuab luam ntawv feem ntau pib nrog platemaking- txheej txheem ntawm kev tsim cov ntawv luam tawm raws li tus qauv tsim qauv kos duab- uas yog lub hauv paus rau tag nrho cov luam ntawv. Thaum cov ntawv tiav tau muab tso rau hauv cov xovxwm luam ntawv, cov khoom tsis xws li siab, tus number case mov, thiab ceev tau hloov kho kom ntseeg tau tias qhov hloov pauv ntawm cov duab nraaj mus rau cov khoom siv substrate. Txawm hais tias cov txheej txheem kev ua haujlwm tshwj xeeb yuav txawv me ntsis ntawm kev luam ntawv sib txawv (xws li flexography lossis offset printing), cov ntsiab lus tseem ceeb tseem zoo ib yam: ua kom tiav cov duab thiab cov ntawv luam tawm los ntawm kev hloov ntawm tus number case.
Thaum lub sijhawm luam ntawv tiag tiag, kev soj ntsuam tas li ntawm tus cwj mem thiab cov khoom siv ruaj khov yog qhov tseem ceeb los xyuas kom meej tias cov qauv luam tawm yog nkig thiab cov xim zoo ib yam. Tsis tas li ntawd, nyob ntawm cov khoom specifications, ntau -xim overprinting yuav tsum tau; Nyob rau hauv cov ntaub ntawv no, kev sau npe meej rau txhua tus neeg xim yuav tsum tau khaws cia kom tsis txhob muaj kev sib raug zoo. Tom qab ua tiav ntawm lub sijhawm luam ntawv, cov ntaub ntawv raug xa mus tom ntej - ua haujlwm - xws li txiav, folding, lossis shaping - kom ua tau raws li qhov kawg ntawm cov khoom yuav tsum tau ua. Tag nrho cov kev ua haujlwm tau muab cov kev xav tau tshwj xeeb ntawm ob qho khoom siv ruaj khov thiab cov neeg ua haujlwm kev txawj ntse los lav qhov zoo ib yam hauv cov khoom tiav.
