Nkag siab txog Technology Tom qab Offset Printing Machine

Taw qhia:

Offset tshuab luam ntawv ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom lag luam zoo. Los ntawm cov ntawv xov xwm thiab cov ntawv xov xwm mus rau daim ntawv qhia thiab ntim, offset printing tau dhau los ua txoj kev nyiam rau kev lag luam luam ntawv. Tab sis cov tshuab no ua haujlwm li cas? Dab tsi yog technology tom qab lawv txoj haujlwm? Hauv tsab xov xwm no, peb yuav nkag mus tob rau hauv qhov tsis sib xws ntawm cov tshuab luam ntawv offset, tshawb txog lawv cov khoom, cov txheej txheem, thiab cov txheej txheem. Txawm hais tias koj yog tus nyiam luam ntawv lossis tsuas yog xav paub txog cov thev naus laus zis uas coj cov ntaub ntawv luam tawm mus rau lub neej, tsab xov xwm no yuav ua rau koj nkag siab zoo txog kev ua haujlwm sab hauv ntawm cov tshuab luam ntawv offset.

Lub hauv paus ntawm Offset Printing:

Offset printing yog cov txheej txheem nrov siv los tsim cov duab thiab cov ntawv ntawm ntau qhov chaw, feem ntau yog ntawv. Lo lus "offset" yog hais txog kev hloov pauv tsis ncaj ntawm cov duab los ntawm cov ntawv luam ntawv mus rau lub substrate. Tsis zoo li kev luam ntawv ncaj qha, xws li letterpress lossis flexography, offset printing siv tus neeg nruab nrab - ib daim pam roj hmab - hloov cov duab mus rau lub substrate. Txoj kev no muaj ntau yam zoo, nrog rau cov duab zoo, kev tsim cov xim zoo nkauj, thiab muaj peev xwm luam tawm ntawm ntau yam ntaub ntawv.

Cov Cheebtsam ntawm Offset Printing Tshuab:

Offset tshuab luam ntawv yog cov txheej txheem nyuaj uas muaj ntau yam tseem ceeb uas ua haujlwm sib haum xeeb. Kev nkag siab txog kev ua haujlwm ntawm txhua feem yog qhov tseem ceeb rau kev nkag siab txog cov thev naus laus zis tom qab offset tshuab luam ntawv. Cia peb tshawb xyuas cov khoom no kom ntxaws:

Printing Phaj:

Hauv plawv ntawm txhua lub tshuab luam ntawv offset yog lub phaj luam ntawv - ib daim ntawv hlau lossis txhuas phaj uas nqa cov duab los luam tawm. Cov duab ntawm lub phaj yog tsim los ntawm cov txheej txheem prepress, qhov twg lub phaj raug UV lub teeb los yog tshuaj lom neeg kev daws teeb meem, hloov chaw xaiv los ua kom lawv tau txais tus cwj mem. Tom qab ntawd lub phaj yog txuas nrog lub phaj lub tog raj kheej ntawm lub tshuab luam ntawv, uas tso cai rau kev tsim cov duab meej thiab zoo ib yam.

Inking System:

Lub inking system yog lub luag haujlwm rau kev siv tus number case rau lub phaj luam ntawv. Nws muaj ib tug series ntawm rollers, nrog rau cov ciav cov menyuam, tus cwj mem roller, thiab distributor roller. Tus ciav menyuam, submerged nyob rau hauv tus cwj mem ciav, sau tus cwj mem thiab hloov mus rau tus cwj mem. Ink roller, nyob rau hauv lem, hloov number case mus rau distributor roller, uas sib npaug ntawm tus number case mus rau lub phaj luam ntawv. Cov txheej txheem inking yog ua tib zoo ntsuas kom ntseeg tau tias cov xim luam tawm raug thiab sib npaug ntawm tus number case.

Lub Cylinder daim pam:

Tom qab cov duab raug xa mus rau lub phaj luam ntawv, nws yuav tsum tau xa mus rau qhov kawg substrate. Qhov no yog qhov uas daim pam roj hmab tuaj ua si. Daim pam lub tog raj kheej nqa cov pam roj hmab, uas yog nias tawm tsam cov ntawv luam ntawv kom tau txais cov duab kos. Qhov zoo ntawm kev siv daim pam roj hmab yog nws qhov yooj yim, cia nws ua raws li cov contours ntawm substrate. Raws li daim pam lub tog raj kheej tig, cov duab inked yog offset rau hauv daim pam, npaj rau theem tom ntej ntawm cov txheej txheem.

Lub Cylinder Impression:

Txhawm rau hloov cov duab los ntawm daim pam mus rau lub substrate, daim pam thiab substrate yuav tsum tau sib cuag nrog ib leeg. Qhov no yog ua tiav los ntawm kev xav lub tog raj kheej. Lub tswv yim lub tog raj kheej nias lub substrate tawm tsam daim pam, tso cai rau cov duab inked mus. Lub siab thov yuav tsum tau ua tib zoo tswj kom ntseeg tau tias kev luam ntawv zoo ib yam thiab tiv thaiv kev puas tsuaj rau lub substrate. Lub tswv yim lub tog raj kheej tuaj yeem hloov kho kom haum rau cov substrates ntawm cov thicknesses sib txawv, ua rau offset luam ntawv ntau yam rau ntau yam kev siv.

Txoj Kev Paper:

Ib sab ntawm cov khoom tseem ceeb, lub tshuab luam ntawv offset kuj tseem muaj txoj hauv kev tsim cov ntawv zoo los coj cov substrate los ntawm cov txheej txheem luam ntawv. Txoj kev ntawv muaj ob peb lub chais thiab lub tog raj kheej uas tso cai rau kev ua haujlwm zoo thiab meej. Los ntawm chav tsev feeder mus rau chav tsev xa khoom, daim ntawv txoj kev ua kom lub zog ntawm lub substrate du, tswj kev sau npe thiab txo qhov kev pheej hmoo ntawm daim ntawv jams. Ib txoj hauv kev zoo yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig kev luam ntawv.

Offset Printing Txheej txheem:

Tam sim no peb tau tshawb xyuas cov khoom tseem ceeb ntawm lub tshuab luam ntawv offset, cia peb ua tib zoo saib ntawm cov txheej txheem ib kauj ruam los ntawm kev koom tes hauv kev tsim cov khoom luam tawm.

Prepress:

Ua ntej luam ntawv tuaj yeem pib, lub phaj luam ntawv yuav tsum tau npaj. Qhov no suav nrog kev nthuav tawm cov phaj rau UV lub teeb lossis tshuaj lom neeg cov tshuaj, uas xaiv hloov nws cov khoom nto kom txais tus number case. Thaum lub phaj npaj txhij, nws txuas nrog lub phaj lub tog raj kheej, npaj tau txais tus cwj mem.

Daim ntawv thov Ink:

Raws li cov ntawv luam ntawv tig rau ntawm lub tog raj kheej lub tog raj kheej, cov txheej txheem inking siv tus number case rau nws qhov chaw. Tus ciav cov menyuam sau cov number case los ntawm tus ciav dej, uas tom qab ntawd xa mus rau tus cwj mem rau cov menyuam thiab muab faib sib npaug rau ntawm daim ntawv luam ntawv. Cov cheeb tsam uas tsis yog duab ntawm lub phaj, uas tawm tsam dej, khaws cov cwj mem, thaum cov duab thaj chaw txais tus cwj mem vim lawv cov kev kho mob thaum lub sij hawm prepress.

Ink Hloov mus rau daim pam:

Tom qab tus number case yog siv rau lub phaj luam ntawv, cov duab yog offset rau hauv daim pam roj hmab li daim pam lub tog raj kheej los ntawm kev sib cuag nrog lub phaj. Daim pam tau txais cov duab kos, uas tam sim no thim rov qab thiab npaj kom xa mus rau lub substrate.

Duab Hloov mus rau Substrate:

Nrog cov duab inked nyob rau ntawm daim pam, lub substrate yog qhia. Lub tswv yim lub tog raj kheej nias lub substrate tawm tsam daim pam, hloov cov duab kos rau ntawm nws qhov chaw. Lub siab thov ua kom lub siab zoo tsis muaj kev puas tsuaj rau lub substrate.

Drying thiab Finishing:

Thaum lub substrate tau txais cov duab inked, nws pib los ntawm cov txheej txheem ziab kom tshem tawm cov dej noo seem thiab ua kom cov number case curing. Ntau txoj kev ziab khaub ncaws, xws li lub teeb cua sov lossis lub tshuab ziab khaub ncaws, tau ua haujlwm kom nrawm rau theem no. Tom qab ziab, cov ntaub ntawv luam tawm tuaj yeem ua tiav cov txheej txheem ntxiv, xws li txiav, folding, lossis khi, kom ua tiav daim ntawv xav tau kawg.

Xaus:

Offset tshuab luam ntawv yog ib qho zoo kawg nkaus sib xyaw ntawm precision engineering thiab advanced technology. Kev sib xyaw ua ke ntawm ntau yam khoom, los ntawm cov ntawv luam ntawv thiab inking system mus rau daim pam thiab lub tog raj kheej, tso cai rau kev tsim cov ntaub ntawv luam tawm zoo nrog cov xim tshwj xeeb thiab kev daws teeb meem. Kev nkag siab txog cov cuab yeej siv tom qab cov tshuab no muab kev pom zoo rau qhov nyuaj ntawm cov txheej txheem luam ntawv thiab cov kauj ruam ua tib zoo koom tes hauv kev tsim cov ntaub ntawv luam tawm. Txawm hais tias koj yog lub tshuab luam ntawv xav tau lossis tsuas yog xav paub los ntawm lub ntiaj teb ntawm kev luam ntawv offset, delving rau hauv cov thev naus laus zis intricacies ntawm offset luam ntawv tshuab muab lub ntsej muag zoo nkauj rau hauv kev kos duab thiab kev tshawb fawb ntawm kev luam tawm.
