Cov khoom siv xim lub thawv ntim hauv lub neej txhua hnub, tshwj xeeb tshaj yog hauv kev thauj mus los thiab kev thauj mus los, cov thawv xim ua lub luag haujlwm tiv thaiv cov khoom hauv cov txheej txheem kev thauj mus los, los ntawm kev puas tsuaj. owadas, nrog rau kev txhim kho tas mus li ntawm cov neeg siv khoom xav tau rau kev ntim khoom, ntxiv rau lub luag haujlwm ntawm lub thawv xim tiv thaiv cov khoom, cov kev xav tau rau cov duab ntawm lub thawv xim kuj tseem txhim kho tas li.Ua kom tau raws li cov kev xav tau ntawm cov neeg siv khoom, ntau yam -color printing tsim yog siv nyob rau hauv cov xim thawv luam ntawv tsim kom ua tiav cov nyhuv ntawm kev txhim kho cov tsos ntawm ntim.Yog li nyob rau hauv cov txheej txheem luam ntawv ntawm ntau xim overprinting, dab tsi yog vim li cas rau phem overprinting?
1. Qhov sib txawv ntawm kev luam ntawv thiab tus cwj mem piv: Yuav kom txuag tau tus nqi thiab nkag siab zoo txog tus nqi ntawm cov khoom siv raw khoom, feem ntau cov xim thawv manufacturers feem ntau muaj ntau tus neeg muab khoom siv rau tib lub sijhawm.Vim qhov sib txawv ntawm kev xa tawm ntawm tus number case luam ntawv los ntawm Txhua tus neeg muag khoom, kev solubility ntawm luam ntawv number case los ntawm cov tuam txhab sib txawv yog qhov sib txawv, uas ua rau muaj qhov tshwm sim ntawm qhov tsis zoo overprinting thaum siv cov luam ntawv number case muab los ntawm cov tuam txhab sib txawv hauv cov txheej txheem overprinting.
2. Kev hloov ntawm overprinting siab: lub siab thaum overprinting yuav tsum tsis txhob loj heev, thiab lub siab ntau dua yuav ua rau kom qhov tshwm sim ntawm overprinting tsis zoo, yog li nws yog ib qho tseem ceeb heev rau peb tswj lub printing siab nyob rau hauv tus txheej txheem ntawm overprinting.
3. Kev siv tus cwj mem luam ntawv kom raug: Nws yog tsim nyog hais tias, qhov tseeb, luam ntawv number case kuj muaj lub neej txee.Lub ed number case yuav maj mam deteriorate tom qab lub sij hawm ntev ntawm kev cia.Yog li ntawd, yog nyob rau hauv cov txheej txheem ntawm overprinting, lub printing. number case siv nyob rau hauv cov xim dhau los yog ze li deteriorated qub number case, ces nws yog ib qho yooj yim los tsim cov xim tsis zoo lub thawv luam ntawv tshwm sim thaum overprinting.
