Qhov txawv ntawm CTP phaj thiab PS phaj yog dab tsi?

Qhov sib txawv ntawm Computer rau Plate (CTP) daim hlau thiab Presensitized (PS) daim hlau yog nyob rau hauv cov txheej txheem ntawm cov phaj ua thiab lawv daim ntawv thov.

CTP daim hlau yog tsim los ntawm kev siv cov duab digital. Lawv raug duab ncaj qha mus rau lub phaj siv lub laser los ntawm kev nthuav tawm lub phaj rau cov duab digital. Cov duab yog pauv mus rau lub phaj saum npoo los ntawm cov tshuaj tiv thaiv laser. CTP daim hlau muaj qib siab ntawm qhov tseeb thiab muaj txiaj ntsig zoo hauv kev tsim cov ntsiab lus zoo thiab lub suab nrov. Lawv feem ntau siv nyob rau hauv cov khoom ntim siab, tshwj xeeb tshaj yog nyob rau hauv offset printing.

Ntawm qhov tod tes, PS daim hlau yog tsim los siv cov txheej txheem analog. Lub phaj yog thawj coated nrog lub teeb-sensitive emulsion thiab ces raug rau lub teeb los ntawm ib tug duab zaj duab xis tsis zoo. Lub emulsion ntawm qhov chaw raug hardens thiab qhov chaw tsis pom kev tseem mos. Tom qab ntawd qhov chaw uas tsis tau raug tshem tawm yog muab ntxuav nrog tus tsim tawm kom pom cov duab ntawm lub phaj. PS daim hlau yog qhov zoo tagnrho rau kev ua haujlwm luv luv thiab feem ntau siv hauv kev luam ntawv ntawm cov ntawv lag luam, cov ntawv tshaj tawm thiab cov ntawv tshaj tawm.

Qhov sib txawv tseem ceeb ntawm CTP daim hlau thiab PS daim hlau nyob hauv lawv cov txheej txheem tsim khoom thiab lawv daim ntawv thov. CTP daim hlau muab cov duab meej thiab ua haujlwm zoo dua rau cov haujlwm luam ntawv loj. Lawv muaj peev xwm lis complex designs nrog siab daws teeb meem thiab tonal ranges. PS daim phiaj xav tau kev txhais tes ntau dua los tsim cov duab thiab zoo dua rau kev ua haujlwm luv luv. Lawv yog cov nqi-zoo thiab tsim cov duab zoo, tab sis tsis nyob rau tib theem ntawm precision li CTP daim hlau.
