Dab tsi yog rotogravure luam ntawv?
Gravure printing is to make the entire surface of the printing plate coated with ink, and then use a special scraping mechanism to remove the ink from the blank part of the ink, so that the ink is only deposited in the mesh cavities of the graphic part of the ink, and then under the action of a greater pressure, the ink will be transferred to the surface of the substrate, to obtain the printed matter. Gravure Printing yog luam ntawv ncaj qha. Daim duab duab ntawm lub tshuab luam ntawv yog concave, thiab qib kev sib txawv, qhov seem ntawm lub tshuab luam ntawv tau tsa, thiab hauv tib lub tog raj kheej plane.
Txheej Txheem Rotogravure yog ib txoj kev hloov pauv ncaj qha rau luam tawm ntoo-pulp fiber ntau raws, hluavtaws, lossis laminated substrates, suav nrog:
-Khiav xws li tus tsiaj, opp, nylon, thiab pe, pvc, celophane
Tsiaj tu
-Carton Pawg Thawj Coj
-Aluminum Ntawv Nyiaj
Rotogravure Printing txheej txheem
Kev luam tawm rotogravure luam ntawv vim yog cov qib siab ntawm lub tshuab luam ntawv, qhov zoo tshaj ntawm lub phaj yog qhov yooj yim dua li LithgroCic Printing, yooj yim rau tus tswv, cov txheej txheem ntws yog raws li hauv qab no:
Kev Npaj Ua Ntej → rau ntawm lub tog raj kheej phaj → kho cov xim sau npe → formal Printing → formal prin-xovxwm ua
Kev piav qhia cov txheej txheem
Thaum lub gravieve printing txheej txheem tshuab luam ntawv lub tog raj kheej rotates nyob rau hauv ink yias uas cov cells engraved sau nrog number case sau nrog number case. Raws li lub tog raj kheej rotates ntshiab ntawm lub ink lauj kaub, muaj cov number case tshaj tawm los ntawm tus kws kho mob hniav. Txuas ntxiv mus, lub tog raj kheej tau coj mus rau hauv kev sib cuag nrog lub substrate, uas tau nias tawm tsam nws los ntawm cov roj hmab muaj kev pab cuam uas npog cov menyuam.
Lub siab ntawm cov menyuam, nrog rau cov capillary kos ntawm lub substrate, tau tshwm sim nyob rau hauv lub mis nyuj ncaj qha los ntawm lub tshuab luam ntawv rau saum npoo ntawm substrate. Raws li cov tshuab luam tawm rotates rotates rov qab mus rau hauv ink yias, cov ntawv luam tawm ntawm cov tshuab luam ntawv ntxiv los ntawm cov xim sib txawv, uas ib txwm muaj cov kua txob sib txawv lossis cov kua roj vanish lossis txheej.
Cov xim zoo nkauj rau kev sau npe xim tau ua tau ntawm cov khoom tsis siv neeg thiab ntev tswj cov tshuab.
Rau lub web-pub luam ntawv xovxwm, tom qab txhua xim tau luam tawm thiab ib qho txheej txheem txheej txheem thov, lub vev xaib yog 'rewound' rau hauv lub ntsej muag tiav.
Tam sim no peb tsom rau kev luam ntawv tuaj yeem cuam tshuam ncaj qha rau kev luam ntawv qhov zoo ntawm ib qho txuas tseem ceeb tshaj plaws - xim sau npe
Tam sim no, feem coob ntawm gravure luam ntawv siv tsis siv neeg daim ntawv sau npe rau kev sau npe, uas zoo heev txhim kho kev ua tiav thiab luam ntawv zoo.
Ntawm lub vev xaib gravure luam ntawv tshuab, muaj ib qho khoom siv tsis siv neeg tiv thaiv nruab. Cov cuab yeej muaj lub taub hau scanning, ib lub tshuab tswj hluav taws xob, lub tshuab hluav taws xob, ib lub cev muaj zog, kev hloov kho cov menyuam thiab lwm yam.
Thaum tus lej txiav txim siab ntawm daim ntawv luam tawm los ntawm cov xim tsis sib xws, yog li cov xim tswj hwm tau tsis sib xws, yog li cov xim tswjfwm kev tswj hwm tau ua ntej lossis cov xim thib ob ntawm cov kev tswj hwm me me, kom tshem tawm cov kev txav me me, kom tshem tawm cov kev txav me tsis raug.
Ib qho ntxiv, tseem muaj cov hauv qab no tuaj yeem cuam tshuam qhov zoo thiab ua haujlwm ntawm kev luam ntawv, tab sis peb yuav muaj cov kev daws teeb meem uas tsim nyog
a) t nws ink yog tsis ncaj nyob rau hauv xim
Qhov tshwm sim ntawm cov kua mem kua ntxhiab tsw ntawm cov ntawv luam tawm. Cov hau kev ntawm kev tshem tawm muaj xws li: kho cov roundness ntawm lub tshuab luam ntawv lub tog raj kheej, kho lub kaum thiab siab ntawm squeeGee lossis hloov lub squeeGee nrog ib qho tshiab.
b) fuzzy thiab cov ntawv luam tawm
Luam tawm cov duab qib thiab qib, muab tshuaj txhuam, qhov tshwm sim ntawm burrs ntawm ntug ntawm daim duab. Kev tshem tawm txoj kev muaj xws li: tshem tawm cov hluav taws xob zoo li qub los ntawm cov ntu, ntxiv polar
c) Thaiv Version
Ink kom qhuav rau hauv lub tshuab luam ntawv mesh, lossis lub tshuab luam ntawv mesh yog tau sau nrog ntawv plaub hau, ntawv hmoov tshwm sim, hu thaiv. Cov txheej txheem tshem tawm yog: Ua kom cov ntsiab lus ntawm cov kuab tshuaj hauv cov number case, txo qhov ceev ntawm number casle qhuav, kev siv lub zog siab lub zog ntawv luam ntawv.
d) ink txeej
Qhov tshwm sim ntawm pob uas tshwm rau ntawm thaj chaw ntawm daim ntawv luam tawm. Kev tshem tawm kev tshem tawm muaj xws li: ntxiv nyuaj ink blending roj, txhim kho lub piscosity ntawm number case. Kho lub kaum sab xis ntawm SqueeGee, nce lub tshuab luam ntawv kev ceev, thiab hloov qhov sib sib zog nqus-kab sib sib zog luam ntawv phaj nrog ib qho ntiav-kab noj hniav luam ntawv phaj.
e) kos
Muaj cov kab ntawm squeeGee ntawm kev luam tawm. Cov txheej txheem tshem tawm yog: Siv cov number cas yam tsis muaj teeb meem txawv teb chaws sib xyaw hauv kev luam ntawv. Kho lub viscosity, cov dryness thiab adhesion ntawm tus cwj mem. Siv cov khoom siv zoo, kho lub kaum sab xis ntawm SqueeGee thiab luam ntawv phaj.
