Kev ua haujlwm ntawm lub thawv luam ntawv tshuab feem ntau pib nrog kev npaj ntawm cov khoom siv raw khoom. Tom qab raug txiav mus rau qhov yuav tsum tau specifications, lub corrugated cardboard nkag mus rau hauv lub tshuab los ntawm ib tug noj system, qhov twg nws undergoes thawj qhov chaw thiab kev sib raug zoo los xyuas kom meej stability thiab precision thaum lub sij hawm thauj. Txhawm rau kom tau txais txiaj ntsig zoo tom qab luam ntawv, daim duab los qhia saum npoo yuav tsum huv thiab tiaj tus; yog tias tsim nyog, ib qho yooj yim ua ntej- txheej txheem kho yog siv los txo qhov cuam tshuam ntawm plua plav lossis impurities ntawm kev luam ntawv zoo.
Thaum nkag mus rau theem luam ntawv, tus number case yog uniformly xa los ntawm tus number case muab system mus rau cov ntawv luam ntawv, thiab tom qab ntawd xa mus rau ntawm daim duab los qhia. Raws li cov khoom xav tau, ib qho -xim lossis ntau- xim luam ntawv tuaj yeem ua tiav; multi-xim luam ntawv yuav tsum tau ua raws li cov txheej txheem overprinting ntawm txhua chav xim- cov txheej txheem uas xav tau qib siab ntawm kev sau npe precision. Nyob rau hauv cov txheej txheem no, cov tsis tseem ceeb xws li number case viscosity, luam ntawv siab, thiab kev khiav hauj lwm ceev yuav tsum tau ua tib zoo tswj, vim hais tias tej yam no ncaj qha cuam tshuam rau lub clarity ntawm cov duab thiab vibrancy ntawm cov xim.
Thaum luam ntawv tiav lawm, daim duab los qhia feem ntau ua tiav los ntawm kev tshaj tawm - theem ua haujlwm - xws li slotting, tuag- txiav, thiab creasing- los ua cov qauv txheej txheem ntawm lub thawv. Nws mam li txav mus rau qhov folding thiab koom nrog theem (txawm los ntawm gluing lossis stapling), thaum kawg ua cov duab ua tiav, cov khoom siv tau. Thoob plaws hauv tag nrho cov kev ua haujlwm no, ntau theem yog nruj nreem sib xyaw ua ke, muab cov kev xav tau nruj ntawm ob qho khoom siv ruaj khov thiab cov txheej txheem ua haujlwm kom ntseeg tau qhov zoo ib yam ntawm cov khoom tiav.
