Laser npav tshuab, yog tias nws tau hais tias nws daim ntawv thov kev lag luam, yog qhov dav heev, ntxiv rau kev ua tiav ntawm ntau cov khoom siv tes ua, cov ntawv thov kev lag luam tshaj plaws.
Tsis ntev los no, ntau tus phooj ywg uas tau ua rau hlau precision pwm ua ntej sab laj laser npav tshuab. Ua ntej cov pwm tsim pwm raug cim rau digitally, lawv txhua tus siv cov tshuab luam ntawv inkjet. Piv nrog inkjet tshuab luam ntawv, laser npav tshuab tau nrawm nrawm thiab tsis muaj lwv tawm. Tus txheej txheem cai siv tau meej thiab ntseeg tau.
