Yuav ua li cas los txhim kho cov luam ntawv ceev ntawm intaglio tshuab luam ntawv?

Lub tshuab luam ntawv ceev ntawm intaglio tshuab luam ntawv yog thawj zaug txiav txim siab los ntawm kev sib kis ntawm cov xim ntawm lub tshuab luam ntawv. Qhov thib ob, qhov ceev luam ntawv yog txiav txim siab los ntawm qhov ua tau zoo ntawm lub qhov cub kom qhuav. Yog tias lub qhov cub ziab kom zoo, tus number case yuav qhuav kom huv si. Tsis tsuas yog tus cwj mem pem hauv ntej yuav tsis yaj, tab sis kuj yuav txo cov kuab tshuaj residual. Peb tuaj yeem txhim kho nws li cas hauv kev ua haujlwm?
Lub tshuab luam ntawv ceev ntawm intaglio tshuab luam ntawv yog thawj zaug txiav txim siab los ntawm kev sib kis ntawm cov xim ntawm lub tshuab luam ntawv. Vim tias cov xim sau npe ntawm cov khoom luam tawm thaum lub sij hawm luam ntawv, yog tias yav dhau los xim number case tsis qhuav, cov xim tom ntej yuav yaj cov xim xim yav dhau los, ua rau xim noj (xim melting) tshwm sim. Yog li ntawd, qhov ntev ntawm qhov kev ncua deb ntawm cov xim luam ntawv ntawm lub tshuab luam ntawv intaglio thiab lub sij hawm ziab ntawm lub ntuj ntev dua, qhov kev luam ntawv yuav nrawm dua. Ntawm qhov tsis sib xws, nws yog qhov nyuaj los txhim kho cov luam ntawv ceev.
Qhov thib ob, qhov ceev luam ntawv yog txiav txim siab los ntawm qhov ua tau zoo ntawm lub qhov cub kom qhuav. Yog tias lub qhov cub ziab kom zoo, tus number case yuav qhuav kom huv si. Tsis tsuas yog tus cwj mem pem hauv ntej yuav tsis yaj, tab sis kuj yuav txo cov kuab tshuaj residual. Intaglio printing number case yog qhuav los ntawm cua kub, tsis yog los ntawm ci.
Ua ntej, thaum plaub luam ntawv number case ntsib tshav kub, nws yuav ua ntej ua ib zaj duab xis, thiab qhov kev pab cuam ntawm cov xim zaj duab xis yuav cuam tshuam rau evaporation ntawm cov kuab tshuaj nyob rau hauv tus number case, uas ua rau lub phenomenon ntawm cuav ziab ntawm tus number case.
Qhov thib ob, tus number case muaj ntau cov kuab tshuaj nrog cov ntsiab lus kub sib txawv, yog li tus nqi ntawm volatilization ntawm txhua qhov hnyav yog qhov sib txawv, uas yog, cov kuab tshuaj qis qis muaj qhov nrawm nrawm dua, thaum lub siab kub kub cov kuab tshuaj muaj qhov qis dua volatilization. Qhov siab dua qhov kub, qhov ceev qhov kub ntawm qhov ntsuas kub qis dua evaporates, thiab qhov seem ntawm qhov kub ntawm qhov kub thiab txias ntau dua.

Muab ob qho laj thawj saum toj no, qhov loj dua lub peev xwm cua sov ntawm lub tshuab luam ntawv kom qhuav lub thawv, qhov nyuaj dua rau cov ntawv luam ntawv kom qhuav. Kev ziab tsis raug lossis tsis ziab ntawm cov ntawv luam tawm tuaj yeem ua rau xim tawg lossis adhesion ntawm cov khoom luam tawm. Cov xim melting lossis adhesion ntawm cov ntaub ntawv luam tawm ua rau nws nyuaj rau qhib lub tshuab luam ntawv ceev ceev. Yog tias qhov luam ntawv nrawm nrawm, cov roj thiab tus lej siv yuav tsum loj. Ib tug loj npaum li cas ntawm cov roj thiab tus cwj mem siv tau yooj yim ua rau xim melting los yog adhesion ntawm cov ntaub ntawv luam tawm, thiab lwm yam, ua rau nws nyuaj rau ua rau kom lub printing ceev. Yog li qhov tseeb qhov sib piv ntawm cov cua sov thiab cov nyiaj tshuab hauv lub thawv ziab ntawm lub tshuab luam ntawv yog qhov yuav tsum tau ua ua ntej rau kev ziab kom qhuav.
Qhov thib ob, yog tias lub tshuab ziab khaub ncaws qhuav ntawm lub tshuab luam ntawv khiav ntawm lub phaj luam ntawv, cov ntawv luam ntawv yuav qhuav rau ntawm daim ntawv luam ntawv rau cov menyuam, thiab qhov qis qis ntawm cov qauv luam tawm yuav tsis luam tawm, thiab cov xim hloov pauv yuav tsis luam tawm tag nrho. Ib zaug ntxiv, cov cua sov los ntawm qhov cub kom qhuav yuav tsum tau ncaj qha ci mus rau zaj duab xis, uas yuav ncab. Yog tias cua tshuab ncaj qha rau ntawm zaj duab xis, nws yuav co. Nyias zaj duab xis stretching thiab co tuaj yeem cuam tshuam qhov tseeb ntawm cov ntawv luam ntawv. Yog li ntawd, thaum xaiv thiab yuav cov tshuab luam ntawv, yuav tsum tau them nyiaj mloog mus rau qhov zoo kom qhuav lub thawv rau intaglio tshuab luam ntawv yuav tsum muaj cov nram qab no nta: tshav kub tsis tuaj yeem ncaj qha ci rau ntawm zaj duab xis nto, cua tsis tuaj yeem ncaj qha rau ntawm cov ntawv luam tawm, thiab cua tsis tuaj yeem khiav mus rau lub phaj luam ntawv. Lub tshuab nqus tsev yuav tsum ntau dua li qhov cua sov, thiab cov cua tso pa yuav tsum du, nrog rau kev ua haujlwm zoo dua qub.
