Cov luam ntawv ntawm nyiaj muas tsuas yog siv cov gravure printing, uas yog vim cov ntawv luam ntawm gravure tau zoo dua los tiv thaiv. Nws yog dav siv nyob rau hauv kev luam tawm anti-counterfeiting. Gravure printing yog characterized los ntawm ib tug loj npaum li cas ntawm tus number case. Yog li ntawd, lub thickness ntawm lub gravure printing kab thiab ntxoov ntxoo ntawm tus number case yog varied. Cov duab nraaj muaj lub siab thiab convex siab, ntau cov khaubncaws sab nraud povtseg, cov kab nrig, thiab kev qhia yooj yim, uas ua rau cov teebmeem loj rau kev ntaus nqi. Gravure yog thawj lub tshuab luam ntawv uas siv rau hauv kev tawm tsam kev tiv thaiv.
Nyob rau hauv cov nqe lus ntawm stamp luam tawm, Tuam Tshoj tus tes-engraved gravure technology yog ntiaj teb-chav kawm. Cov tes tuav qhov riam phom thiab kev tsim txuj ci zoo nkauj yog tsis ua raws li lwm cov phaj ua. Lub portraits ntawm Suav thiab txawv teb chaws banknotes yeej ib txwm tau txhais tes-carved, thiab tes-carved qhia cov yam ntxwv ntawm cov cim. Cov tes-sib-sib-sib-luam-ua khoom muag muaj cov lej quav, zoo tes thiab muaj zog tiv thaiv. Txawm li cas los xij, muaj ob qho teeb meem hauv kev ntxuav tes. Firstly, nws yog qhov siv tau thiab tsis tsim kom muaj kev ua khoom sai. Tsis tas li ntawd xwb, vim hais tias cov tes yuav tsum siv cov riam, cov ntawv xuab zeb yog "V" zoo li lub qhov zaws ntawm qhov tob tob. Cov cwj mem kua ntim khoom ntawm tus zawj ntawm qhov no tsis zoo li ntawd. Yog hais tias siv txoj hlua yeeb yaj kiab, tus cwj mem nyob hauv qhov zawj yooj yim tau yooj yim, thiab cov ink txheej ntawm daim kab ntawv tsis txaus thiab tuab. Qhov no yog ob qho teeb meem uas yuav tsum tau daws. Hauv kev daws qhov teeb meem ntawm kev ua haujlwm, thaum muab cov ntaub ntawv pov tseg txawv teb chaws, lub portrait yog loj dua thiab cov duab loj dua thiab txhuam. Tom qab daim ntawv qhia carving, qhov kev nthuav dav ntawm daim duab liab ces siv los ua tus qauv; siv no template ua pwm, lub tshuab shrinking yog siv los ntswg ntawm steel phaj. Engraving portraits uas ua raws li cov lus qhia.
Sensible kub, engraving tooj liab phaj yog yooj yim dua thiab ntau dua li ncaj qha engraving steel phaj. Raws li kev daws teeb meem ntawm "V" ntawm qhov zawj, nws yog ib qho tsim nyog los siv lub peev xwm ntawm kev cuam tshuam cov txheej txheem. Cov txheej txheem ntawm qhov etching ncaj qha etches ib leeg-qhib nraaj zaj duab xis ntawm ib lub phaj uas muaj coated nrog cov ntaub ntawv. Lub zog ntawm lub phom tooj liab yog tsawg, thiab lwm cov high-hardness daim hlau yuav muab pov rau sab nraum qab ntawm lub phaj tooj liab. Los sis them ib txheej ntawm tooj ntawm ib sab tawv. Cov phom tooj liab uas tau raug kho nrog cov khees me ntsis lawm tuaj tom qab qhib lub plhaub ntim ntawm 1 hli-tuab yas phaj los ntawm cov xovxwm kub, thiab cov phaj yas yog ua rau cov yas phaj loj loj los ntawm kev txiav thiab txiav siab ntau zaus, thiab ib lub luj yas loj siv. Cov phaj tooj liab yog ploj lawm, cov phaj tooj liab rov qab los rau ntawm daim phiaj nickel nyem, thiab cov nickel intaglio phaj yog thaum kawg rau kev siv ntawm lub tshuab. Lub thawv uas ua los ntawm cov txheej txheem no muaj qhov U-shaped groove, thiab tau muaj tus cwj pwm txuag zoo, thiab cov kab ntawv luam tawm tau muaj txheej xoom txheej thiab khov tes zoo. Tsis tas li ntawd, txoj kev tuaj yeem ua rau cov ntawv me me thiab nyias nyias kab. Tam sim no cov ntawv me me ntawv me me yuav tsum 150μm, yog li ntawd lub me gravure micro-phau ntawv tsuas yog pom nyob rau hauv lub iav magnifying, thiab nws yog pom meej.
Lub gravure invisible duab los ntawm etching txoj kev muaj zoo refractive index thiab pom xim hloov. Nyob rau tib lub sij hawm, qhov kev sib tw ntawm qhov txujci no daws qhov teeb meem ntawm tus cim ntim ntawm tus qauv gravure, thiab daws qhov teeb meem ntawm qhov tsis zoo ntawm kev siv tes dawb. Txawm li cas los xij, nyob rau hauv qhov loj version ntawm corrosive txoj kev, nws yog ib qhov tsim nyog yuav tau siv cov txheej txheem ntawm kev coj, electroplating thiab ntau piracy ua daim ntawv luam. Qhov no kuj muaj qhov teeb meem ntawm kev tsis txaus. Yuav kom daws tau qhov teeb meem no, tib neeg tau tshawb nrhiav seb puas yuav siv cov txheej txheem etching. Qhov teeb meem ntawm kev ncaj qha ua ib qho gravure ntawm lub tshuab.
