Nws tuaj yeem hais tias peb lub neej niaj hnub tsis tuaj yeem sib cais los ntawm kev siv ntawv. Txawm hais tias nws yog ntawv ua lag luam, ntawv hauv tsev, ntawv kawm, thiab lwm yam, txhua tus ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv peb lub neej. Cov ntawv yob carbonless uas tsim los ntawm Kaifeng Ntawv yog dav siv nyob rau hauv ntau yam, yog li yuav ua li cas xam nws qhov hnyav?
Txij li thaum yob ntawm cov ntawv tsis muaj cov ntawv feem ntau yog muag los ntawm qhov hnyav, nws yog qhov tsim nyog los ntsuas qhov yob ntawm cov ntawv tsis muaj cov ntawv. Kev xam qhov hnyav tuaj yeem ua ntej xam qhov ntev ntawm cov yob ntawm cov ntawv tsis muaj carbon raws li cov qauv kev suav ntawm lub voj voog, thiab tom qab ntawd siv Daim Ntawv Dav * ntev kom tau txais thaj tsam ntawm daim ntawv yob no, thiab tom qab ntawd thaj tsam * gram hnyav kom tau txais hnyav ntawm ib daim ntawv yob.
Feem ntau hais lus, yob ntawm cov ntawv tsis muaj carbon yog thawj zaug ntawm daim ntawv los ntawm lub tshuab ntawv, thiab tom qab ntawd txiav thiab dov los ntawm ib lub rewinder raws li daim ntawv yob ntawm txawv specifications. 787mm thiab lwm yam tshwj xeeb sib txawv, nyob rau hauv tus txheej txheem ntawm dov daim ntawv, nws yuav tsum tau xyuas kom meej tias cov carbonless daim ntawv yob yog zoo ib yam nyob rau hauv nruj, zoo zoo trimmed, thiab cov pob qij txha yuav tsum tiaj tus thiab pom ntawm qhov muag liab qab. Cov ntawv luam tawm carbonless tuaj yeem siv rau kev luam ntawv teb, ntim tsis siv neeg, thiab lwm yam. Rau kev lag luam thiab kev lag luam siv.
