Kev tsim cov hnab embossed luam ntawv yog txheej txheem txheej txheem zoo. Los ntawm yob cov yas zaj duab xis mus rau lub hnab ntim cov yeeb yuj hauv peb txhais tes, cov kauj ruam tseem ceeb yog:
Ua ntej-kev npaj thiab phaj ua - Intaglio luam ntawv - Lamination (rau ntau- txheej hnab) - Txiav - Lub hnab ntim khoom. Hauv qab no, peb yuav txheeb xyuas txhua kauj ruam hauv kev nthuav dav:
Kauj Ruam 1: Ua ntej- nias Preparation thiab Plate Making
Cov qauv tsim thiab kev pom zoo: Ua ntej, sib txuas lus nrog tus neeg siv khoom los txiav txim qhov loj, qauv, xim thiab cov ntawv ntawm lub hnab. Thaum lub sij hawm tsim cov txheej txheem, nws yog ib qho tsim nyog yuav tsum tau ua kom meej meej lub hnab hom (xws li peb - sab sealing, nruab nrab - hauv qab sealing) thiab cov txheej txheem luam ntawv (sab hauv printing lossis deg printing).
Pov thawj (electronic engraving): Lub intaglio luam ntawv phaj yog lub tog raj kheej tooj liab nrog suav tsis txheeb me me kev nyuaj siab engraved rau ntawm nws qhov chaw. Tam sim no, txoj hauv kev tseem ceeb yog hluav taws xob engraving rau kev pov thawj. Nws yuav carve sib txawv qhov tob ntawm qhov ntawm lub phaj lub tog raj kheej raws li cov qauv tsim, tuav tus number case. Qhov tob ntawm lub qhov, qhov ntau tus number case nws tuav tau, thiab cov xim luam tawm tsaus dua.
Theem 2: Intaglio Printing
Rolling thiab phaj mounting: Nruab lub tshuab luam ntawv substrate (xws li BOPP, PET zaj duab xis) ntawm lub tshuab unwinding, thiab tib lub sij hawm ntxig rau ua ntej - ua lub tog raj kheej luam ntawv rau hauv chav luam ntawv.
Mixing number case: Raws li tus neeg siv khoom teev cov xim, npaj cov xim tshwj xeeb thiab tswj cov viscosity kom zoo. Rau intaglio luam ntawv, tus number case muaj viscosity tsawg thiab dries sai. Thaum lub sij hawm luam ntawv, cov kuab tshuaj yuav tsum tau muab ntxiv los yog manually kom muaj kev ruaj ntseg ntawm viscosity.
Cov txheej txheem luam ntawv: Raws li cov yeeb yaj kiab hla ntawm lub phaj luam ntawv thiab lub tog raj kheej lub tswv yim, lub siab hloov cov number case hauv cov qhov mesh mus rau zaj duab xis.
Kev ziab thiab txias: Tom qab txhua xim luam tawm, zaj duab xis tam sim ntawd nkag mus rau qhov cub kom qhuav. Cov cua kub tshem tawm cov kuab tshuaj nyob rau hauv tus number case, ua rau cov number case txheej solidify. Tom qab ntawd nws dhau los ntawm cov cua txias kom txias thiab zoo li tus, tiv thaiv cov yeeb yaj kiab los ntawm deforming vim cua sov.
Rolling cov prints: Tom qab tag nrho cov xim luam tawm tiav, cov ntawv luam ntawv ntev tau muab dov rau hauv cov duab yob thiab tos cov txheej txheem tom ntej.
Theem 3: Composites (rau ntau- txheej txheej hnab)
Ntau lub hnab ntim khoom (xws li lub hnab khoom noj txom ncauj, lub hnab nqus tsev) xav tau kev sib xyaw ntawm ntau yam khoom kom ua tiav cov khoom tshwj xeeb.
Txheej thiab ziab: Ib txheej ntawm cov nplaum yog sib npaug rau saum npoo ntawm cov ntawv luam tawm, thiab tom qab ntawd nws qhuav hauv qhov cub.
Composting: Muab lwm yam khoom siv (xws li CPP, PE zaj duab xis lossis aluminium ntawv ci) nrog cov ntawv luam tawm hauv qab kub thiab kub siab siv lub tshuab xovxwm.
Kauj Ruam 4: Txiav
Cov yob dav ntawm cov khoom sib xyaw lossis cov ntawv luam tawm yuav tsum tau txiav rau hauv ob peb lub voj voog nqaim ntawm qhov xav tau dav raws li cov lus qhia ntawm lub hnab - ua tshuab lossis cov neeg siv khoom xav tau.
Kauj Ruam 5: Ua Lub Hnab
Thaum tshav kub kub sealing thiab txiav: Muab cov rolls ntawm zaj duab xis tso rau hauv lub hnab - ua tshuab. Siv cov riam sib khi ua kom sov, los ntawm kev sib xyaw ua ke ntawm lub siab, qhov kub thiab lub sijhawm, txheej txheej hauv zaj duab xis (feem ntau yog cov cua sov- cov khoom sib khi xws li CPP lossis PE) yog melted thiab sib txuas ua ke los tsim lub hnab sealing ntug (xws li peb- sab sealing lossis rov qab sealing), thaum tseem txiav qhov sib cais ntawm ib lub hnab thiab lwm yam.
Sau cov khoom tiav: Thaum kawg ntawm lub hnab - ua tshuab, lub hnab ntim khoom tiav yuav raug sau cia thiab txheeb ua ntej.
Kev tswj kom zoo thoob plaws hauv cov txheej txheem
Thoob plaws hauv tag nrho cov txheej txheem, kev tswj kom zoo muaj nyob txhua qhov chaw:
Cov txheej txheem luam ntawv: Ib qho kev tshuaj xyuas online lossis tib neeg cov neeg ua haujlwm yuav ua qhov tseeb - sijhawm kuaj xyuas kom paub tseeb tias cov xim sau npe yog qhov tseeb thiab saib xyuas qhov tsis zoo xws li cov cwj mem lossis kab.
Cov txheej txheem tseem ceeb: Ua random tshuaj xyuas ntawm cov cim tseem ceeb xws li luam ntawv ceev (kab xev kuaj), lub zog sib xyaw, thiab lub zog sealing.
Kev tshuaj xyuas cov khoom kawg: Txheeb xyuas qhov loj ntawm lub hnab ntim khoom tiav, seb cov ntsaws ruaj ruaj yog nruj, thiab seb cov qauv puas tiav, thiab lwm yam.
Tom qab kawm txog tag nrho cov txheej txheem ntawm intaglio- cov hnab luam tawm, koj puas xav paub cov ntsiab lus ua haujlwm tshwj xeeb ntawm qee cov kauj ruam? Thov sau ib tsab xov rau qhov kawg ntawm tsab xov xwm. Kuv yuav zoo siab los teb koj cov lus nug rau koj.
