Raws li ib qho tseem ceeb ntawm cov khoom ntim khoom, cov txheej txheem ntawm cov ntawv ntim khoom plig yuav tsum sib npaug ntawm kev zoo nkauj nrog lub zog thiab kev ua haujlwm. Los ntawm kev xaiv cov khoom siv raw mus rau cov khoom tiav tiav, txhua kauj ruam yuav tsum muaj kev tswj hwm nruj kom ntseeg tau tias cov khoom kawg ua tau raws li kev xav tau ntawm kev lag luam. Kab lus no yuav piav qhia txog cov txheej txheem tsim khoom ntawm lub thawv khoom plig, npog cov kauj ruam tseem ceeb ntawm kev tsim mus rau molding.
I. Tsim thiab Plate Ua
Kev tsim cov thawv ntawv khoom plig pib hauv theem tsim. Cov neeg tsim khoom yuav tsum tau txiav txim siab qhov loj, cov duab, xim, thiab cov qauv luam tawm ntawm lub thawv khoom plig raws li cov neeg siv khoom xav tau thiab cov yam ntxwv ntawm cov khoom. Tom qab kev tsim tiav lawm, yuav tsum tau ua ib daim ntawv luam ntawv, feem ntau yog siv CTP (Computer-to-Plate) thev naus laus zis los tso tawm cov ntaub ntawv digital ncaj qha mus rau lub phaj luam ntawv, txhim kho qhov raug thiab ua haujlwm tau zoo. Rau lub thawv khoom plig nrog cov qauv nyuaj, qhov tuag- txiav pwm kuj tseem yuav tsum tau ua rau kev tuag tom ntej- txiav cov txheej txheem.
II. Cov ntawv xaiv thiab ua ntej- kho
Cov khoom siv hauv paus rau lub thawv khoom plig feem ntau yog cov duab los qhia, corrugated ntawv, lossis ntawv tshwj xeeb, nyob ntawm lub hom phiaj thiab thauj khoom -cov cai ntawm lub thawv khoom plig. Cov ntawv hnyav hnyav li ntawm 200-400 g / m², nrog cov thawv khoom plig siab kawg uas siv cov ntawv tshwj xeeb tuab lossis ntawv kub stamping.
Tom qab xaiv cov khoom siv, daim ntawv yuav tsum tau ntub dej kom ruaj ntseg thaum luam ntawv thiab tuag- txiav, tiv thaiv deformation los yog warping vim huab cua hloov. Qee qhov siab- lub thawv khoom plig kawg kuj tau lamination (xws li glossy lossis matte lamination) txhawm rau txhim kho qhov ci ntsa iab lossis tiv thaiv- cov khoom plam.
III. Printing thiab Surface Finishing
Kev luam ntawv yog ib qho ntawm cov txheej txheem tseem ceeb hauv cov ntawv ntim khoom plig, cuam tshuam ncaj qha rau nws qhov kev pom zoo. Cov txheej txheem luam ntawv muaj xws li:
1. Offset printing (lithography): Tsim nyog rau cov qauv tsim, siab xim fidelity, thiab haum rau ntau lawm.
2. Flexographic luam ntawv: Ib puag ncig tus phooj ywg thiab tus nqi qis, feem ntau siv rau kev tsim qauv yooj yim.
3. Digital printing: Tsim nyog rau me me -batch customization xav tau, yuav tsum tsis muaj phaj ua, thiab muaj kev yooj yim.
Tom qab luam ntawv, nyob ntawm seb cov qauv tsim, cov txheej txheem hauv qab no yuav tsim nyog:
• Kub stamping (kub / nyiaj): Ua kom muaj txiaj ntsig zoo ntawm lub thawv khoom plig.
• UV Spot Txheej: Txhim kho qhov kev puas tsuaj thiab gloss ntawm qee qhov chaw.
• Embossing/Debossing: Ntxiv tactile xav thiab ib tug peb - cov nyhuv.
IV. Tuag-txiav thiab Creasing
Tuag- txiav yog cov txheej txheem ntawm kev txiav cov ntawv luam tawm kom meej rau cov qauv tsim, thaum creasing yog ua ntej - nias ntawm creases los npaj rau tom ntej folding. Cov kauj ruam no siv lub tshuab tuag- txiav tshuab nrog ua ntej- ua tuag los txiav cov ntawv rau hauv lub thawv uas xav tau. Tuag- txiav qhov tseeb ncaj qha cuam tshuam rau kev sib dhos ntawm lub thawv khoom plig, yog li qhov ntse ntawm qhov tuag thiab lub tshuab siab yuav tsum tau tswj nruj me ntsis.
V. Folding thiab Gluing
Tom qab tuag- txiav, daim duab los qhia yuav tsum tau muab tais manually lossis mechanically los tsim cov qauv ntawm lub thawv khoom plig. Tom qab folding, ib puag ncig tus phooj ywg adhesives (xws li hmoov txhuv nplej siab, kua nplaum dawb, los yog kub yaj kua nplaum) yog siv rau gluing los xyuas kom meej tias lub hau, lub cev, thiab lwm yam khoom yog ruaj khov. Qee qhov siab- lub thawv khoom plig kawg tuaj yeem siv cov qauv kaw hauv qab lossis tus nplaig- thiab- qauv tsim los txo qis kev siv kua nplaum thiab txhim kho ib puag ncig tus phooj ywg.
VI. Kev sib dhos thiab kev soj ntsuam zoo Tom qab folding thiab gluing, lub thawv khoom plig nkag mus rau theem sib dhos. Cov neeg ua haujlwm lossis cov khoom siv tsis siv neeg tso lub hauv ob sab phlu (xws li EVA ua npuas ncauj, ntaub lo lo ntxhuav, thiab lwm yam) rau hauv lub thawv, ua kom lub hau qhib thiab kaw. Tom qab kev sib sau ua ke, yuav tsum tau kuaj xyuas kom zoo, suav nrog:
• Kev tshuaj xyuas qhov tshwm sim: Clear printing, ua kom kub stamping, thiab tsis muaj khawb los yog stains.
• Kev tshuaj xyuas tus qauv: Lub cev lub cev muaj zog, du folds, thiab du qhib thiab kaw.
• Dimensional Inspection: Ua raws li cov neeg siv khoom tshwj xeeb.
VII. Kev ntim khoom thiab kev xa khoom zoo-cov ntawv pov thawj cov thawv yuav raug ntim cov plua plav, feem ntau yog qhwv hauv zaj duab xis lossis muab tso rau hauv cov thawv kom tsis txhob muaj kev puas tsuaj thaum thauj. Qee qhov siab- lub thawv khoom plig kawg tseem yuav ntxiv nrog cov dej noo- ntawv pov thawj los yog npuas qhwv rau kev tiv thaiv ntxiv. Thaum kawg, cov khoom raug ntim thiab xa tawm raws li kev txiav txim siab rau cov neeg siv khoom.
Cov txheej txheem tsim khoom ntawm lub thawv khoom plig muaj ntau theem, suav nrog kev tsim, luam ntawv, tuag- txiav, thiab gluing. Txhua kauj ruam yuav tsum tau ua tib zoo saib xyuas kom paub meej qhov kawg ntawm cov khoom zoo nkauj, practicality, thiab ib puag ncig tus phooj ywg. Nrog rau kev lag luam loj hlob xav tau rau kev ntim khoom tus kheej, kev tsim cov ntawv ntim khoom plig yuav tsom ntau dua rau kev hloov kho, kev txawj ntse, thiab kev ruaj ntseg yav tom ntej kom tau raws li cov kev xav tau ntawm kev ntim khoom sib txawv.
