Kev tsim cov txheej txheem ntawm cov ntawv thawv

Cov txheej txheem ntau lawm ntawm cov thawv ntawv tuaj yeem muab faib ua plaub theem: tsim, luam ntawv, tuag- txiav, thiab tsim. Ua ntej, qhov loj thiab cov duab ntawm lub thawv ntawv yog tsim raws li nws lub hom phiaj siv, thiab txoj kev sib dhos yog txiav txim siab. Tom qab ntawd, cov qauv lossis cov ntawv sau ntxiv rau ntawm daim ntawv siv offset lossis flexographic luam ntawv. Tom ntej no, ib tug tuag- txiav tshuab yog siv los txiav cov ntawv rau hauv cov duab tshwj xeeb thiab nias tawm cov kab. Thaum kawg, cov npoo yog folded thiab glued manually los yog siv cov cuab yeej siv tshuab ua kom tiav cov khoom tiav. Hauv cov txheej txheem niaj hnub no, qee lub thawv ntawv yog laminated lossis waxed los txhim kho cov dej tsis zoo los yog kev puas tsuaj. Nws yog ib qho tsim nyog sau cia tias kev tsim cov thawv ntawv yuav tsum sib npaug tus nqi thiab kev ua haujlwm; Piv txwv li, cov duab los qhia tuab yog tsim rau hnyav - lub luag haujlwm ntim, thaum cov khoom siv hnyav feem ntau siv rau hauv kev lag luam khoom noj lossis khoom plig.
