Cov Ntawv Dawb Me Me Cov Ntawv Luam Ntawv Luam Ntawv rau hauv qhov chaw luam ntawv kev puas tsuaj, yuav tsum ua tib zoo teb rau

Cov Ntawv Dawb Me Me Cov Ntawv Luam Ntawv Luam Ntawv rau hauv luam ntawv "qhov chaw puas tsuaj", yuav tsum ua tib zoo teb rau

Hauv kev luam ntawv, ntim hnab luam ntawv bar code yog qhov tseem ceeb tshaj plaws ntawm kev lag luam luam ntawv. Nws yog ib qho yooj yim los ua qhov tseem ceeb ntawm kev tshuaj xyuas ntawm cov khoom ntim khoom ntawm cov khoom noj, tshuaj thiab lwm yam lag luam, thiab kuj tseem tuaj yeem tso cov kev xav tsis zoo rau cov neeg siv khoom. Cov hauv qab no yog cov lus piav qhia yooj yim ntawm txoj hauv kev luam tawm bar codes thiab ceev faj.

Yuav ua li cas luam barcodes

1, kev siv cov khoom siv luam ntawv rau batch luam ntawv thiab luam tawm, uas yog kev lag luam bar code daim ntawv lo ntau lawm, txoj kev no feem ntau yog bar code thiab qauv ua ke luam ntawv.

2, los ntawm lub computer tswj, raws sij hawm luam ntawv bar code ntawv thiab bar code ntaub ntawv.

Cov qub yog tsim rau ntau tus lej bar code nrog cov ntsiab lus ruaj khov thiab tib cov ntsiab lus, thiab tsim thiab luam tawm tib lub sijhawm raws li cov duab ntim sab nrauv. Lub tom kawg tuaj yeem tswj tau los ntawm lub khoos phis tawj kom ua tiav kev luam ntawv sai sai raws li qhov xav tau, muaj zog yoog raws.

Technical thiab cov ntaub ntawv yuav tsum tau rau cov txheej txheem luam ntawv thaum luam ntawv bar codes

1, qhov luaj li cas: qhov luaj li cas ntawm cov nplai yog txiav txim siab raws li qhov loj ntawm lub hnab, bar code feem ntau yog thawj loj ncaj qha luam ntawv.

2, xim sib txuam: tus number case dub yog xim xim xim xim, xim dawb yog xim dawb dawb. Thaum xaiv lwm xim, ceev faj xaiv raws li lub teeb liab ntawm cov xim.

3, qhov yuav tsum tau muaj rau lub substrate: nyob rau hauv cov nqe lus ntawm optical yam ntxwv, lub substrate yuav tsum muaj zoo optical dispersion yam ntxwv, tsis muaj specular xav.

4. Cov khoom yuav tsum tau muaj: Cov ntaub ntawv uas muaj huab cua tsis zoo, ruaj khov loj tom qab kev ntxhov siab, cov xim zoo, kev nthuav dav me me, me me permeability, smoothness thiab tiav yuav tsum tau xaiv.

5, qhov yuav tsum tau muaj ntawm tus number case: nyob rau hauv tus number case xim collocation los xav txog cov xim ntawm tus number case. Vim tias qhov bar code luam ntawv yog daim teb luam ntawv, qhov kev xav tau ntawm kev luam ntawv tuaj yeem ua tiav thiab cov txheej txheem kho qhov muag muaj feem cuam tshuam nrog lub thickness ntawm tus number case txheej hauv txheej txheem luam ntawv, qhov kev xav ceev ntawm cov khoom luam ntawv tau nce nrog. Qhov nce ntawm tus number case thickness, thaum tus number case thickness nce mus txog ib tug tej yam nqi, qhov ceev mus txog saturation, yog li xyuam xim rau lub concentration ntawm tus number case thiab thickness ntawm tus number case txheej.
