Kev ceev faj rau ntim thiab luam ntawv QR Code

Kev ceev faj rau ntim thiab luam ntawv QR Code

QR code tuaj yeem yog monochrome dub lossis ntau xim superimposed.Lub ntsiab tseem ceeb cuam tshuam rau qhov zoo ntawm QR code luam ntawv yog xim sib piv thiab overprinting yuam kev.

1. Xim sib txawv

Cov xim tsis txaus ntawm cov ntawv xov xwm QR code yuav cuam tshuam rau kev lees paub ntawm QR code los ntawm lub xov tooj ntawm tes software.Cov yam ntxwv kho qhov muag ntawm cov cim barcode luam ntawv: Yuav kom nyeem tau qhov kev ntseeg siab, tom qab luam ntawv, cov kab thiab qhov chaw hauv barcode yuav tsum muaj qhov sib txawv, qhov kev xav ntawm qhov chaw yuav tsum loj npaum li qhov ua tau, thiab qhov cuam tshuam ntawm cov kab yuav tsum yog qhov sib txawv. me me li ua tau.Raws li lub teb chaws tus qauv, qhov dawb ntawm cov ntawv xov xwm hauv tsev yog ntau tshaj 50%, thiab cov luam ntawv ib txwm tuaj yeem ua tau raws li cov cai ntawm QR code.Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias thaum ua QR code ntawm cov ntawv xov xwm, tus editor yuav tsum tau ceeb toom kom tsis txhob ntxiv qhov ntxoov ntxoo los tiv thaiv qhov xwm txheej uas qhov sib txawv tsis txaus los cuam tshuam rau kev nyeem ntawv.

2. Overprinting yuam kev

Feem ntau yog hais txog xim QR code.QR code yuav tsum huv si thiab meej thaum luam ntawv.Feem ntau, peb teev tias qhov siab tshaj plaws ntawm qhov yuam kev overprint (overprint yuam kev ntawm lub ntsiab xim thiab daim duab) yuav tsum tsawg tshaj li los yog sib npaug rau 0.4 npaug ntawm nominal dav ntawm txoj kab nqaim barcode.

Raws li lub teb chaws tus qauv, qhov overprinting yuam kev ntawm cov ntawv xov xwm yuav tsum tsawg tshaj li los yog sib npaug zos rau 0.3 hli.Qhov tseeb, qee cov ntawv xov xwm ntawm lossis siab dua lub xeev theem nrog cov cuab yeej luam ntawv siab dua thiab cov kev xav tau zoo dua tuaj yeem ua tau raws li cov qauv hauv qhov no.Rau qee cov ntawv xov xwm hauv zos thiab hauv nroog, yog tias kev luam tawm tsis ruaj khov, nws raug nquahu kom luam QR code rau ib xim, kom tsis txhob muaj teeb meem overprinting.

Kev luam ntawv tsis muaj qee yam

Thaum luam ntawv, ceev faj kom tsis txhob poob cov ntsiab lus ntawm lub phaj luam ntawv, kom tsis txhob ua rau nyuaj rau kev nyeem QR code.Hauv kev luam ntawv, vim yog lub phaj luam ntawv lossis daim pam, nws yog ib qho yooj yim los ua qhov tsis xws luag ntawm cov ntawv luam tawm.Rau me ntsis "fragmented" qauv ntawm ob-dimensional code, tshwj xeeb yuav tsum tau them nyiaj mloog mus rau lub pre-xovxwm thiab tom qab kuaj xyuas.

Printing ink teeb meem

Txhawm rau tswj qhov kev ua yuam kev loj ntawm ob-seem code cim, tus yuam sij yog tswj cov xim number case thiab luam ntawv siab thaum luam ntawv kom paub meej tias qhov kev kho dua tshiab ntawm ob-dimensional code kab txaij.Raws li ib txwm muaj, peb yuav tsum xyuas kom meej tias tus number case yog "me me hauv dej thiab me me hauv number case", thiab tib lub sijhawm kom ntseeg tau qhov tsim nyog tuab ntawm cov number case txheej.Tsis muaj qhov cuav streak tshwm sim los ntawm qhov tsis tshua muaj siab lossis xim xim tsis txaus;tsis muaj streak diffusion tshwm sim los ntawm lub siab ntau dhau los yog tus number case loj.
