Cov sib txawv ntawm mettetpress luam ntawv thiab flexographic luam ntawv yog feem ntau los cuam tshuam rau hauv cov luam ntawv ntawm lub tshuab luam ntawv, luam tawm cov xwm txheej, kev tiv thaiv thiab kev tiv thaiv ib puag ncig. Cov hauv qab no yog qhov kev tshawb fawb tshwj xeeb:
Cov yam ntxwv sib txawv ntawm cov luam ntawv:
Cov ntawv nyeem thiab duab ib feem ntawm letterpress luam ntawv phaj yog tsa, thiab lub hardness yog tus siab. Kev lig kev cai, cov hom khoom coj thiab ntoo ntoo yog siv ntau. Niaj hnub nimno feem ntau siv cov paib txheej txheem cob cov phiaj. Lub thickness feem ntau tsawg dua 1mm. Cov kev qhia tshwj xeeb yog 0.8mm thiab 0.95mm. Lub hardness ntawm lub tshuab luam ntawv tiav yog feem ntau ib puag ncig 90 degrees ntawm ntug dej.
Cov ntawv nyeem thiab duab ib feem ntawm cov ntawv luam ntawv flexographic no tseem tau tsa, tab sis cov khoom siv yog softer thiab elastic. Cov roj hmab, roj hmab lossis cov paib luam tawm luam ntawv. Lub thickness feem ntau ntawm 1 thiab 5 mm, thiab lub hardness nyob nruab nrab ntawm 30 thiab 70 degrees.
Txawv number cask thiab number hloov tshuab:
LetterPress luam ntawv siv cov kua mem kua qab nrog qee yam viscosity. Los ntawm kev xa tawm cov neeg xa khoom tsis zoo, suav nrog tus lej xov tooj, ib qho kua mem kua txiv, thiab lwm yam nyob ntev.
Flexographic Printing siv tsawg - viscosity, high {} {}} Cov kua ntses luv luv hloov mus rau hauv cov kab mob anilox. Lub anilox cov menyuam yog ob qho tib si Ink hloov cov menyuam thiab cov kua membering cov menyuam thiab tuaj yeem muab cov tshuaj tsis raug raws li cov kev xav tau.
Cov ntawv luam tawm yog txawv ntawm cov xwm txheej siv tau.
Cov xim number cases ntawm letterpress luam ntawv yog thicker txheej txheej ci yog li ntawm cov ntawv luam tawm hauv nruab nrab, thiab nws tuaj yeem luam tawm ntawm rougher substrates. Nws yog feem ntau siv rau phau ntawv luam ntawv, cov cim lag luam, ntim thiab kho kom zoo nkauj luam ntawv, thiab lwm yam.
Flexographic Printing muaj tag nrho cov kua mem kua tuab, txheej khoom noj, xim ci, thiab cov luam ntawv raug ntawm txog 175 kab / hauv. Nws yog qhov tshwj xeeb rau scenes nrog High cov ntawv sau siv cov tshuab no (xws li ntim cov tshuab hluav taws xob (xws li siv cov ntaub qhwv ntsej muag), xws li cov ntaub ntawv hauv tshuab (li 70))
Kev ua haujlwm txawv thiab txij nkawm:
Tus qauv ntawm letterpress luam ntawv presses yog cov sib txawv, thiab kev ua haujlwm thiab txij nkawm yog qhov nyuaj.
Cov qauv ntawm cov ntawv luam tawm ntawm Flexographic presses yog yooj yim, yooj yim ua lag luam, thiab kho tau yooj yim thiab tswj hwm. Tus nqi ntawm flexographic luam ntawv xovxwm nrog tib yam muaj nuj nqi yog hais txog 30-50% ntawm qhov offset lossis gravation Printing nias.
Kev tiv thaiv txawv:
Tus Paste number case siv hauv ntawv sau ntawv yuav muaj qee qhov kev tiv thaiv ib puag ncig ib puag ncig piv rau cov kua hauv flexage luam ntawv.
Flexographic Printing tuaj yeem siv tsis tau tsis -} {{} {}}}}}}}}}}}}}}}}}}} Kev tiv thaiv ib puag ncig kev tiv thaiv ib puag ncig ib puag ncig.
