Taw qhia rau Rotogravure Printing Process

rotogravure luam ntawv yog dab tsi?

Gravure luam ntawv yog ua kom tag nrho saum npoo ntawm daim ntawv luam ntawv coated nrog tus number case, thiab tom qab ntawd siv cov txheej txheem tshwj xeeb txhawm rau tshem tawm tus number case los ntawm qhov khoob ntawm tus number case, kom tus number case tsuas yog tso rau hauv mesh kab noj hniav ntawm cov duab ntawm tus number case, thiab tom qab ntawd nyob rau hauv qhov kev txiav txim siab ntau dua, tus number case yuav raug xa mus rau saum npoo ntawm cov ntawv luam tawm. Gravure printing yog ncaj qha luam ntawv. Cov duab nraaj ntawm lub phaj luam ntawv yog concave, thiab cov degree ntawm concavity nrog rau theem ntawm cov duab muaj ntau ntxoov, qhov dawb paug ib feem ntawm lub phaj luam ntawv yog tsa, thiab nyob rau hauv tib lub cylinder dav hlau.

Cov txheej txheem rotogravure yog ib txoj hauv kev xa ncaj qha rau kev luam ntawv mus rau ntoo-pulp fiber ntau raws li, hluavtaws, lossis laminated substrates, suav nrog:

- Cov yeeb yaj kiab xws li PET, OPP, nylon, thiab PE, PVC, Cellophane

—Cov ntawv

-Carton board

- Aluminium ntawv ci

Rotogravure luam ntawv txheej txheem

Rotogravure luam ntawv vim yog qib siab ntawm automation ntawm lub tshuab luam ntawv, qhov zoo ntawm lub phaj yog zoo, thiab yog li cov txheej txheem kev lag luam yog yooj yim dua lithographic luam ntawv, yooj yim rau tus tswv, cov txheej txheem ntws raws li hauv qab no:

Kev npaj ua ntej luam ntawv → ntawm lub tog raj kheej phaj → kho cov xim sau npe → kev luam ntawv → tom qab xovxwm

Txheej txheem piav qhia

Thaum lub sij hawm gravure luam ntawv txheej txheem lub tog raj kheej luam ntawv rotates nyob rau hauv tus number case lauj kaub uas cov engraved hlwb sau nrog number case. Raws li lub tog raj kheej rotates ntshiab ntawm tus number case lauj kaub, txhua tus number case ntau dhau raug tshem tawm los ntawm tus kws kho mob hniav. Ntxiv mus, lub tog raj kheej yog coj mus rau hauv kev sib cuag nrog lub substrate, uas yog nias tawm tsam nws los ntawm cov roj hmab npog impression roller.

Lub siab ntawm cov menyuam, nrog rau kev kos capillary ntawm lub substrate, ua rau kev hloov pauv ncaj qha ntawm tus number case los ntawm cov hlwb hauv lub tog raj kheej luam ntawv mus rau qhov chaw ntawm lub substrate. Raws li cov tshuab luam ntawv tig rov qab rau hauv lub lauj kaub, qhov chaw luam tawm ntawm lub substrate pib los ntawm lub tshuab ziab khaub ncaws thiab mus rau lub tshuab luam ntawv tom ntej, uas feem ntau yog xim sib txawv lossis tej zaum yuav yog kua roj vanish lossis txheej.

Precise xim rau xim sau npe yog ua tau los ntawm tsis siv neeg sab thiab ntev register tswj systems.

Rau lub web-fed luam ntawv xovxwm, tom qab txhua xim tau luam tawm thiab ib co coatings thov, lub web yog 'rewound' rau hauv ib tug tiav yob.

Tam sim no peb tsom mus rau cov txheej txheem luam ntawv tuaj yeem cuam tshuam ncaj qha rau kev luam ntawv zoo ntawm ib qho tseem ceeb tshaj plaws txuas - xim sau npe

Niaj hnub no, feem ntau ntawm cov tshuab luam ntawv gravure yuav siv cov xim tsis siv neeg sau npe rau cov qauv sau npe, uas zoo heev txhim kho cov ntawv sau npe thiab kev luam ntawv zoo.

Nyob rau hauv lub web gravure tshuab luam ntawv, muaj ib tug tsis siv neeg overprinting ntaus ntawv ntsia. Cov cuab yeej muaj xws li lub taub hau scanning, lub tshuab hluav taws xob mem tes, lub tshuab hluav taws xob, lub tshuab hloov kho, kev hloov kho cov menyuam thiab lwm yam.

Thaum lub cim overprint ntawm daim ntawv luam tawm los ntawm lub taub hau scanning, lub mem tes teeb liab yuav raug xa mus rau lub tshuab hluav taws xob, yog tias xim thib ob ntawm lub cim overprint tsis ncaj ncees lawm ua ntej lossis tom qab thawj xim ntawm lub cim, qhov tshwm sim ntawm lub sij hawm mem tes yuav tsis sib npaug, yog li lub tshuab hluav taws xob pib tswj lub cev muaj zog, kom thawj xim thiab xim thib ob ntawm lub overprint ntawm cov txheej txheem ntawm cov txheej txheem me me.

Tsis tas li ntawd, kuj tseem muaj cov hauv qab no uas tuaj yeem cuam tshuam qhov zoo thiab kev ua haujlwm ntawm kev luam ntawv, tab sis peb yuav muaj cov kev daws teeb meem tsim nyog

a) T nws tus number case yog xim tsis sib xws

Lub phenomenon ntawm periodic number case hloov ntawm cov ntaub ntawv luam tawm. Cov txheej txheem ntawm kev tshem tawm muaj xws li: kho lub roundness ntawm lub tshuab luam ntawv phaj lub tog raj kheej, kho lub kaum sab xis thiab siab ntawm lub squeegee los yog hloov lub squeegee nrog ib tug tshiab.

b) Fuzzy thiab linty prints

Luam tawm cov duab qib thiab qib, muab tshuaj txhuam, qhov tshwm sim ntawm burrs ntawm ntug ntawm daim duab. Txoj kev tshem tawm muaj xws li: tshem tawm hluav taws xob zoo li qub los ntawm qhov chaw ntawm lub substrate, ntxiv cov polar solvents rau tus number case, tsim kom muaj kev luam ntawv siab, thiab kho qhov chaw ntawm lub squeegee thiab lwm yam.

c) blocked version

Ink drying nyob rau hauv lub tshuab luam ntawv phaj mesh, los yog lub tshuab luam ntawv phaj mesh qhov yog sau nrog ntawv plaub hau, ntawv hmoov tshwm sim, hu ua thaiv. Txoj kev tshem tawm yog: nce cov ntsiab lus ntawm cov kuab tshuaj nyob rau hauv tus number case, txo qhov ceev ntawm tus number case kom qhuav, siv cov ntaub ntawv muaj zog saum npoo.

d) Ink spillage

Lub phenomenon ntawm cov me ntsis tshwm nyob rau hauv daim teb ib feem ntawm lub luam. Txoj kev tshem tawm muaj xws li: ntxiv cov roj pleev xim tawv tawv, txhim kho cov viscosity ntawm tus number case. Kho lub kaum sab xis ntawm lub squeegee, ua kom lub tshuab luam ntawv nrawm, thiab hloov cov ntawv sib sib zog nqus-cavity luam ntawv nrog lub phaj ntiav-cavity luam ntawv.

e) Kov

Muaj cov cim ntawm squeegee ntawm daim ntawv luam. Txoj kev tshem tawm yog: siv tus cwj mem huv si yam tsis muaj teeb meem txawv teb chaws sib xyaw hauv kev luam ntawv. Kho cov viscosity, dryness thiab adhesion ntawm tus number case. Siv cov squeegee zoo, kho lub kaum sab xis ntawm squeegee thiab luam ntawv phaj.

OYANG tus tsim engineers soj ntsuam thiab optimize lub tshuab qauv raws li ib tug series ntawm cov teeb meem nyob rau hauv cov txheej txheem luam ntawv, thiab tsim lub Honor Sereis ELS Rotog ravure Printing Tshuab los ntawm kev xav ntawm kev daws qhov mob cov ntsiab lus ntawm cov neeg siv thiab kev lag luam.

Rotogravure Txheej txheem zoo thiab kev siv

The process offers the ability to transfer ink consistently, across a wide range of densities, and at high speeds, making it suitable for applications which require high image quality, such as publishing, packaging, labels, security print, and decorative printing.

Cov xwm txheej ruaj khov ntawm lub tog raj kheej luam ntawv siv ua rau gravure luam ntawv cov txheej txheem zoo tshaj plaws rau kev muab cov ntawv luam tawm zoo rau ntev heev lossis tsis tu ncua rov ua haujlwm, xa cov nqi zoo dua lwm cov txheej txheem.

OYANG kev txawj ntse thiab kev paub

Ib tug formidable innovator, tsom rau tsim tus nqi rau nws cov neeg siv khoom, cov khoom los ntawm OYANG Rotogravure xovxwm ua, nyob rau hauv tsuas yog peb xyoos OYANG Rotogravure xovxwm tau tsim ib tug zoo lub koob npe nrov thiab zoo lub npe nyob rau hauv Tuam Tshoj, thiab muaj ntau lub teb chaws thiab cheeb tsam nyob ib ncig ntawm lub ntiaj teb no uas cov neeg muas zaub factories muaj peb Honour series hluav taws xob ncej rotogravure printing presses, thiab lawv khiav heev stably.

Ib tug zoo sib xws innovator, OYANG tau teeb tsa cov qauv tshiab hauv web-film gravure luam ntawv nyob rau hauv xav tau cov chaw xws li saj zawg zog ntim nrog nws Honor® series rotogravure presses . Kev ua tiav cov txiaj ntsig zoo tshaj plaws ntawm cov khoom lag luam qib siab laminated saj zawg zog ntim ua rau muaj kev sib tw tshiab rau cov txheej txheem luam ntawv gravure, tab sis kev txhim kho thev naus laus zis, kev siv yooj yim, kev hloov pauv ceev ceev thiab txo cov khib nyiab ntawm OYANG presses ua rau lawv yog ib qho kev xaiv sab saum toj rau cov neeg siv khoom hauv Suav teb thiab thoob ntiaj teb.
