Lub ntsej muag ncaj qha laser engraving yog tag nrho ua tiav, ob-kauj ruam, cov yeeb yaj kiab tsis pub platemaking, uas yog qhov tseem ceeb ntawm cov lag luam luam ntawv ntim. Qhov txheej txheem prepress yog nyob deb ntawm qhov cuam tshuam ntawm kev luam ntawv tag nrho. Direct laser engraving thev naus laus zis ua tau yooj yim ntawm qhov txheej txheem prepress thiab txhim kho zoo heev ntawm cov txheej txheem no. Qhov no tseem tuaj yeem ua rau lub tshuab luam ntawv teb tau sai sai rau kev ua lag luam thiab muab kev pabcuam sai. Dab tsi ntxiv, cov txheej txheem platemaking sai no tuaj yeem tsim nyog rau kev luam ntawv flexographic, vijtsam qeeb mentshis luam ntawv, ntawv luam ntawv thiab tsis muaj dej tsis tuaj yeem luam tawm.
Cov ntsiab cai tseem ceeb ntawm kev ncaj qha laser engraving
Holmium laser engraving yog lub tes tsho phaj ua cov txheej txheem. Lub tshuab luam ntawv yog qhwv rau ntawm lub nruas steel lub cev thiab tom qab ntawd tig ntawm qhov chaw nrawm heev (txog 2400rpm). Thaum lub nruas yog tig rau ntawm kev kub ceev, nws yuav txav mus raws kab rov tav thiab dhau lub laser engraving ntaus, raug tag nrho cov luam ntawv phaj mus rau qhov siab-siv CO2 laser nqaj. Lub tshuab luam ntawv phaj nqus lub zog ntawm lub nqaj thiab ua rau muaj kev cuam tshuam thermal ntawm cov ntawv luam tawm khoom hauv thaj chaw engraved. Tom qab txua, lub tshuab luam ntawv tuaj yeem siv ncaj qha rau kev luam ntawv tom qab kev ua tiav sai.
Kev tshaj lij 3D software ua rau nws yooj yim rau cov neeg ua haujlwm los tswj kev tsim cov dots kom ntseeg tau ntau dua qhov tseeb hauv thaj chaw nraaj, suav nrog txoj kab nqes ntawm cov dot tsim, qhov siab dua, thiab qhov luaj li cas hauv qab ntawm cov teev.
Cov txheej txheem kev tsim cov phaj no tsim nyog rau ntau yam khoom siv, suav nrog cov ntawv polymers, EPDM (ethylene-propylene-diene roj hmab (suav nrog dicyclopentadiene)) roj hmab tes tsho, thiab photosensitive emulsions rau electroformed nickel mesh rollers.
Hauv kev luam ntawv flexographic, nyem luam ntawv, thiab tsis muaj dej ntawm cov ntawv luam tawm txheej txheem, thaj chaw tsis yog-nraaj yog ablated los ntawm lub teeb laser, thiab thaj chaw nraaj yog tshwj tseg. Hauv kev tsim cov tshuaj ntsuam teb luam tawm daim hlau, cov khoom siv hauv thaj chaw nraaj yog ablated los ua cov ntawv qhib qhib mesh. Qhov no kuj yog lub hauv paus rau kev ua kom paub zoo number case hloov thaum lub sijhawm luam ntawv.
Cov txiaj ntsig zoo ntawm kev ncaj qha laser engraving
Direct laser engraving muaj cov zoo li nram no:
Kev siv ntau dua ntawm kev ua tau zoo-qhov ncaj qha laser engraving txheej txheem yog yooj yim yooj yim, thiab lub sijhawm xav tau tsuas yog ib nrab ntawm cov tsoos engraving txheej txheem. Rov ua xaj rau cov phaj ntau lawm tsuas yog tsim cov ntaub ntawv xa tawm-yog li cov txheej txheem npaj tag nrho tsuas yog ob peb feeb xwb.
Kev ua tau zoo tshaj plaws phaj-qhov zoo tshaj plaws phaj loj txhais tau tias zoo tshaj plaws number case hloov thiab siab zoo ntawm cov kab zoo kos duab. Yog li cov barcodes me me thiab cov ntawv tsis tas yuav kho dua kom pom tseeb thiab thaij duab. Lub hauv paus ruaj ntseg ua kom dot qhov nce ntxiv hauv thaj chaw siab carving me me. Cov dots tsis txhawb nqa kuj tseem tuaj yeem ua kom ruaj khov qhov ntev tom qab hnav ntev ntev. Dot nyem tsim tuaj yeem tiv thaiv kom tsis txhob muaj plua plav hauv cov chaw uas tsis yog nraaj.
Cov khoom zoo ntawm cov luam ntawv phaj yog ruaj khov dua-ob lub tshuab luam ntawv ua ua ntej thiab tom qab tuaj yeem ua tiav zoo ib yam.
Kev pab cuam ntev tshaj lub neej-tsis muaj phaj o / kev ua tsis tiav. Seamless luam daim hlau kuj tseem muaj.
Tus nqi ntawm kev ua phaj yog qis-tsis muaj kev txhim kho thiab lub sijhawm ziab ntev yog xav tau. Kev siv nyiaj tsuas yog kev siv lub zog ntawm cov haujlwm ua haujlwm, ib qho me me ntawm CO2 roj thiab tus nqi luam ntawv lub tes tsho nws tus kheej. Lub zog me me ntawm qhov system txhais tau hais tias ntau qhov chaw tau txais kev cawm.
Kev ua haujlwm zoo ib puag ncig-zoo ib yam, tsis muaj tshuaj lom thiab UV lub teeb raug siv thoob plaws hauv lub phaj ua cov txheej txheem, tsuas yog siv dej me me thiab CO2 xwb. Qhov no txhais tau hais tias tsis muaj qhov xav tau cov pa phem tawm thoob plaws.
Cov txiaj ntsig zoo
Tam sim no, muaj cov xov tooj ntawm cov khoom siv hluav taws xob muag tawm ntawm kev ua lag luam. Cov tshuab kos ntau hom yog qhov tseem ceeb rau flexographic phaj teb, uas ua tau raws li qhov xav tau ntawm cov qauv dav dav thiab nqaim-cov chaw xa khoom. Kev tshaj lij nqaim-thav duab engraving tuaj yeem siv rau kev tsim cov ntawv luam tawm xws li flexographic, letterpress, tsis pub dej tawm tshuab luam ntawv, thiab cov vijtsam teb. Nws muab cov kev daws teeb meem tiav uas tuaj yeem ntsib ntau yam kev txhawb nqa. Kev ntsuas vias vias kev ntsuas tshuab yog qhov kev xaiv zoo rau cov hom loj.
Feem ntau, cov tshuab luam ntawv tuaj yeem nkag siab ntawm cov luam ntawv phaj tsim cov txheej txheem, tswj cov nqi tsis pub dhau, thiab xyuas kom meej cov khoom zoo thiab ruaj khov ntawm luam ntawv phaj. Nrog rau lub sijhawm luv luv ntawm prepress ntau lawm lub voj voog, cov tshuab luam ntawv muaj kev yoog raws kev lag luam, vim hais tias qhov ntev ntawm kev lag luam xa lub sijhawm tau dhau los ua cov qauv tseem ceeb ntawm kev sib tw.
