Cov txheej txheem luam ntawv sib txawv muaj qhov xav tau sib txawv rau tus lej. Raws li kev siv tus lej tiag, qee cov khoom ntxiv tau ntxiv rau tus lej. Piv txwv li, offset luam ntawv number case muaj qhov viscosity loj, dej tsis kam zoo, gravure luam ntawv number case yog tus nyias thiab muaj cov kua zoo; Kev tshuaj ntsuam luam ntawv yuav tsum muaj qhov zoo permeability.
Hais txog cov txheej txheem tsim nyog, kev tshuaj ntsuam luam ntawv muaj qhov zoo, tshwj xeeb tshaj yog hauv cov yas amorphous, kho vajtse, khoom siv hluav taws xob thiab cov khoom siv ncaj qha rau cov neeg siv khoom lag luam. Txawm li cas los xij, kev tshuaj ntsuam luam ntawv tsis tuaj yeem cuam tshuam nrog kev lag luam luam ntawv ntawm thaj chaw me me thiab cov txheej txheej tsis xwm yeem, yog li nws tau yug los rau ncoo tshuab luam ntawv. Txawm hais tias cov txheej txheem ntawm silk screen luam ntawv thiab ncoo luam ntawv sib txawv, lawv cov chaw tsim khoom muaj qhov zoo sib xws.
Thawj txheej txheej luam ntawv siv tib tus lej ib yam li luam ntawv lo lo lo ntxhuav, tab sis tus lej siv nyob hauv ib puag ncig luam ntawv sib txawv muaj qhov hloov pauv tau. Piv txwv li, tus neeg siv tsis xav tau lub ncoo luam ntawv number case kom muaj lub permeability ntawm txhob lo lo ntxhuav tshuaj ntsuam luam ntawv number case txhua, tab sis yuav kom nws kom muaj thixotropy zoo dua thiab qhov saum npoo qhuav, thiaj li ua kom ntseeg tau tias cov txheej txheem xa los ntawm phaj hlau mus rau lub taub hau roj hmab thiab substrate yog qhov tseeb dua. Kev siv cov ntawv tshwj xeeb luam ntawv number case yuav ua rau nws yooj yim los txhim kho kev luam ntawv zoo.
Cov tuam txhab lag luam txawv teb chaws tau coj cov hlau lead hauv kev tsim cov ntawv tshwj xeeb luam ntawv number case, uas ua rau qhov ntom ntom ntom ntawm tus lej nyob hauv qhov ntau yam tas li los ntawm kev ua ntawm cov tshuaj ntxiv, thiaj li ua kom cov kua hloov pauv zoo ib yam hauv cov txheej txheem luam ntawv. Cov txheej txheem ntawm kev hloov pauv tus lej kuj tseem cuam tshuam nrog cov khoom ntawm lub ncoo luam ntawv taub hau. Lub hom phiaj ntawm kev tswj hwm qhov nro ntawm lub ncoo luam ntawv lub taub hau nyob rau hauv ib puag ncig zoo ib yam li ntawm cov ntaub qhwv lub hauv ncoo luam ntawv yog txhawm rau txhim kho tus lej hloov pauv kom zoo.
Ib qho ntxiv, nws tsim nyog sau cia tias silk screen luam ntawv number case thiab ncoo luam ntawv number case yog thoob ntiaj teb, tab sis yuav tsum tau ntxiv cov khoom los hloov qhov luam tawm. Yog li ntawd, thaum tsis muaj tshwj xeeb ncoo luam ntawv number case, txhob lo lo ntxhuav npo luam ntawv number case tuaj yeem siv tau dua.
