Yog li ntawd, tsis hais yam twg ntawm kev luam ntawv qauv yog siv rau luam ntawv, ua ntej tsim qauv ntawm cov khoom siv, nrog rau deformation yuam kev tso cai nyob rau hauv txhua qhov kev ua kom zoo nkauj Cov ntawv tom qab kev cog lus, txhawm rau kom ntseeg tau tias qhov raug kho kom raug ntawm cov qauv, cov ntawv nyeem thiab bar code ntawm lub khob.
1, cov kev taw qhia ntawm lub tshav kub ntsws daim ntawv lo qauv
Seb lub tshav kub ntsws yeeb yaj kiab saws ua yeeb yam, nws cov luam ntawv yog nyob rau hom luam ntawv, thiab cov kev taw qhia ntawm cov qauv ntawm daim phiaj luam ntawv yuav tsum muaj qhov zoo. Tam sim no tseem muaj ib zaj duab xis ntsws tuaj yeem luam tawm, hauv qhov no, tus qauv ntawm lub phaj yuav tsum tau thim rov qab.
2, theem ntawm tshav kub ntsws zaj duab xis daim ntawv lo qauv tsim qauv
Txwv tsis pub dhau los ntawm cov luam ntawv ntawm kev luam ntawv ntawm flexographic luam ntawv, yog tias lub ntsej muag shrink yog qhov tsis zoo, thiab kev siv ntawm lub gravental tuaj yeem xav tau theem ntawm daim duab kom muaj kev nplua nuj.
3, qhov loj me ntawm lub ntsws zaj duab xis daim ntawv lo
Lub kab rov tav shrinkage tus nqi ntawm tshav kub ntsws cov khoom siv tau luam tawm yog 45% thiab 70%, thiab nws yuav tsum yog yuav tsum yog 1% ~ 8% Cov. Txawm li cas los xij, thaum zaj yeeb yaj kiab tau cog lus nrawm, nws tsuas yog txwv, thiab kab rov tav thiab ntsug tsis tuaj yeem ua tiav. Txhawm rau kom ntseeg tau tias qhov raug kho kom raug ntawm cov qauv, cov ntawv sau thiab kev cog lus, nws yog qhov tsim nyog kom yog qhov loj me thiab deformation ntsuas raws li qhov xwm txheej tiag tiag. Rau cov ntaub ntawv tua hluav taws uas yuav tsum tau tig daim ntawv zaj duab xis mus rau hauv lub tog raj kheej thiab nws yuav tsum tau sau tseg rau hauv seem sib khi, yog li tsis cuam tshuam rau txoj kev sib tham sai.
4, Thaum Tshav Kub Zaum Shrink Zaj Duab Xis Qhwv Bar Code Chaw
Feem ntau, cov kev coj ua ntawm kev tso chaw ntawm bar code yuav tsum ua rau cov kev taw qhia ntawm cov luam ntawv, tsis li nws yuav cuam tshuam rau cov txiaj ntsig ntawm cov qauv thiab ua rau kev ua tsis ncaj ncees. Qhov chaw nyob ntawm cov cim code yuav tsum txiav txim siab ua raws li txoj ntsiab cai ntawm tsis yog deformation, yooj yim nyeem thiab phaj kev ua. Ntawd yog, nws yuav tsum tau teeb tsa ntawm sab xis ntawm lub ntsiab ntawm cov khoom lag luam ntim lossis lub dav hlau txuas rau ntawm cov chaw tseem ceeb ntawm cov khoom lag luam ntim khoom loj. Kev noj rau hauv tus account cov yam ntxwv ntawm cov kev cai luam tawm, yog li ntawd cov luam ntawv tawm hauv txoj cai barcle ntawm bar code, yog li tsis cuam tshuam txog kev nyeem ntawv raug. Vim tias qhov sib txawv hauv cov hau kev ntim thiab cov yam ntxwv, txoj haujlwm barcode version kuj sib txawv. Nws yog qhov zoo tshaj plaws los luam tus barcode ntawm ib sab ntawm daim ntawv lo, tab sis cov npoo curvature ntawm barcode lub cim yuav tsum tsis pub tshaj 30 degree; Bar code feem ntau yog thawj qhov loj ncaj qha luam ntawv, thiab kom muaj kev cuam tshuam nrog cov hauj lwm ntawm lub koom haum yuav tsum tau tswj hwm ntawm 80% ~ 200%. Barcode scaling piv tau muaj kev cuam tshuam zoo rau cov luam ntawv dhau tus nqi, thaum ntsuas piv yog 100%, luam ntawv dhau los yog 97.3%; Thaum lub zoom piv yog 90%, kev luam ntawv tus nqi yog 95.7%; Thaum lub zoom piv yog 85%, tus qauv luam ntawv tus nqi yog 25%; Thaum lub zoom piv yog tsawg dua 80%, tus nqi luam ntawv tus lej tsuas yog 10%. Yog li ntawd, scaluling printing yog qhov zoo tshaj plaws ua tiav los ntawm qhov chaw bar code qhov chaw muaj peev xwm ua kom qhov chaw bar tuaj yeem raug txiav tawm, tab sis qhov siab tseem ceeb yog tsis tsawg tshaj 2/3 ntawm cov qub siab. Rau luam ntawv kub ntsws ntim khoom ntim, nws yog ib qho tsim nyog los xav txog txoj haujlwm ntawm zaj duab xis, thiab kab ke los daws nws ua ntej, yog li los kho nws thaum lub sij hawm phaj kev ua.
