Kev Tshawb Fawb Tom Qab Offset Printing Machine

Offset printing yog cov txheej txheem luam ntawv dav siv uas tau hloov pauv kev lag luam. Nws muab cov kev daws teeb meem zoo tshaj plaws thiab raug nqi luam ntawv rau ntau yam ntaub ntawv, suav nrog cov ntawv xov xwm, ntawv xov xwm, phau ntawv, thiab cov khoom ntim. Hauv qab qhov xwm txheej, cov tshuab luam ntawv offset siv cov qauv kev tshawb fawb los tsim cov ntawv luam tawm kom raug thiab pom zoo. Hauv tsab xov xwm no, peb tshawb fawb txog kev tshawb fawb tom qab offset tshuab luam ntawv, tshuaj xyuas cov khoom tseem ceeb, txheej txheem, thiab kev nce qib uas ua rau cov thev naus laus zis no ua tau zoo thiab txhim khu kev qha.

Keeb kwm ntawm Offset Printing

Ua ntej dhia mus rau hauv kev tshawb fawb ntawm offset tshuab luam ntawv, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib rov qab los ntawm keeb kwm ntawm cov txheej txheem luam ntawv no. Offset printing yog thawj zaug tsim nyob rau hauv lub xyoo pua puv 19 raws li ib qho kev xaiv rau cov ntawv luam ntawv uas tseem ceeb tshaj plaws. Nws tau txais koob meej vim nws qhov kev txhim kho ntau yam, ceev, thiab kev ua tau zoo. Cov txheej txheem cuam tshuam nrog kev hloov tus cwj mem los ntawm lub phaj mus rau ib daim pam roj hmab ua ntej xa mus rau qhov chaw luam ntawv. Txoj kev tsis ncaj ntawm kev luam ntawv no tshem tawm qhov xav tau ncaj qha rau cov ntawv luam ntawv rau ntawm daim ntawv, ua rau cov ntawv luam tawm zoo dua nrog cov duab zoo dua thiab ua kom tiav.

Cov Ntsiab Cai ntawm Offset Printing

Txhawm rau nkag siab txog kev tshawb fawb tom qab offset tshuab luam ntawv, nws yog ib qho tseem ceeb kom nkag siab cov ntsiab lus tseem ceeb ntawm cov txheej txheem no. Offset luam ntawv tso siab rau lub hauv paus ntsiab lus uas cov roj thiab dej tsis sib tov. Tus cwj mem siv hauv cov txheej txheem no yog roj-raws li, thaum lub phaj luam ntawv thiab lwm qhov ntawm lub cev siv cov kev daws teeb meem dej. Lub tswv yim no yog qhov tseem ceeb hauv kev ua tiav cov ntawv luam tawm kom raug thiab vibrant.

Lub luag haujlwm ntawm Cov Ntawv Luam Ntawv

Offset tshuab luam ntawv siv cov ntawv luam ntawv, feem ntau yog ua los ntawm txhuas lossis polyester, ua lub hauv paus tsim cov ntawv luam tawm. Cov phaj no ua lub luag haujlwm tseem ceeb hauv kev xa cov number case mus rau qhov chaw luam ntawv. Lawv muaj cov txheej txheem photosensitive uas ua rau lub teeb thiab ua rau muaj kev hloov pauv tshuaj, thaum kawg tsim cov duab los luam tawm. Cov phaj yog mounted rau lub tog raj kheej nyob rau hauv lub tshuab luam ntawv, tso cai rau kom meej thiab zoo ib yam luam ntawv.

Nyob rau hauv cov txheej txheem hu ua phaj imaging, cov ntawv luam tawm raug rau lub teeb hnyav, feem ntau siv lasers lossis lub teeb-emitting diodes (LEDs). Qhov cuam tshuam ua rau cov txheej txheej photosensitive rau cov tawv nqaij nyob rau hauv cov cheeb tsam uas cov duab yuav luam tawm, thaum cov cheeb tsam uas tsis yog duab tseem mos. Qhov kev sib txawv no ua rau lub hauv paus rau kev hloov tus cwj mem thaum lub sijhawm luam ntawv.

Nkag siab txog cov txheej txheem Offset

Cov txheej txheem luam ntawv offset suav nrog ntau theem sib txawv uas ua rau nws qhov tshwj xeeb luam tawm zoo thiab ua haujlwm tau zoo. Cov theem no suav nrog prepress, luam ntawv, thiab ua haujlwm tom qab xovxwm.

Prepress

Ua ntej luam ntawv tuaj yeem pib, prepress kev ua ub no npaj cov ntawv luam ntawv thiab xyuas kom meej tias lawv raug ua kom raug. Cov theem no suav nrog daim phiaj duab, raws li tau hais dhau los, qhov twg cov phiaj xwm raug rau lub teeb los tsim cov duab. Tsis tas li ntawd, prepress suav nrog kev ua haujlwm xws li kev npaj kos duab, kev sib cais xim, thiab kev txiav txim siab - kev npaj ntawm ntau nplooj ntawv ntawm ib lub phaj luam ntawv rau kev luam ntawv zoo.

Kev luam ntawv

Thaum lub sij hawm prepress tiav, cov txheej txheem luam ntawv tiag tiag pib. Hauv cov tshuab luam ntawv offset, tus number case raug xa mus los ntawm lub phaj mus rau qhov chaw luam ntawv los ntawm ib daim pam nruab nrab lub tog raj kheej. Ib tug series ntawm rollers tswj cov ndlwg ntawm number case, xyuas kom meej thiab zoo ib yam kev pab cuam thoob plaws hauv lub printing txheej txheem. Daim pam lub tog raj kheej, coated nrog ib daim pam roj hmab, tau txais tus cwj mem los ntawm lub phaj thiab tom qab ntawd hloov nws mus rau qhov chaw luam ntawv, feem ntau yog daim ntawv.

Txoj kev hloov pauv tsis ncaj no, uas yog tus cwj mem thawj zaug los rau hauv kev sib cuag nrog cov pam roj hmab ua ntej ncav cuag daim ntawv, yog dab tsi muab offset luam ntawv nws lub npe. Los ntawm kev siv daim pam roj hmab resilient, offset luam ntawv tshem tawm qhov ncaj qha siab pom nyob rau hauv lwm yam kev luam ntawv, ua rau tsis tshua hnav thiab tsim kua muag ntawm cov ntawv luam ntawv. Nws tseem ua rau kev luam ntawv ntawm ntau yam ntaub ntawv nrog sib txawv textures, thicknesses, thiab finishes.

Post-Press

Tom qab cov txheej txheem luam ntawv tiav lawm, cov haujlwm tom qab xovxwm yuav tsum ua kom ntseeg tau tias cov ntaub ntawv luam tawm tau zoo tshaj plaws. Cov kev ua ub no yuav suav nrog kev txiav, khi, folding, thiab lwm yam ua tiav kom xa cov khoom kawg uas ua tau raws li qhov xav tau tshwj xeeb. Cov ntawv sau npe raug ua tiav thaum lub sij hawm offset printing txheej txheem pab rau kev ua tiav ntawm cov txheej txheem tom qab xovxwm.

Science of Ink thiab Xim

Kev siv tus cwj mem yog ib qho tseem ceeb ntawm offset printing, ncaj qha cuam tshuam rau qhov zoo thiab vibrancy ntawm cov ntawv luam tawm. Inks siv hauv cov tshuab luam ntawv offset feem ntau yog roj thiab muaj cov xim uas tsim cov xim uas xav tau. Cov pigments no yog cov hmoov av zoo uas tau tov nrog cov roj los ua tus cwj mem du thiab zoo ib yam. Cov roj-raws li tus cwj mem ua kom ntseeg tau tias nws ua raws li cov ntawv luam tawm thiab yooj yim xa mus rau qhov chaw luam ntawv.

Kev tswj xim yog lwm yam kev tshawb fawb ntawm offset luam ntawv. Ua kom tiav cov xim raug thiab zoo ib yam ntawm cov ntawv luam tawm sib txawv thiab cov haujlwm luam ntawv yuav tsum tau ua tib zoo saib xyuas cov xim inks thiab calibration ntawm lub tshuab luam ntawv. Cov chaw luam ntawv tshaj lij siv cov txheej txheem tswj cov xim thiab cov software tshwj xeeb los xyuas kom meej qhov sib xws hauv cov xim luam tawm.

Kev nce qib hauv Offset Printing Machine

Offset tshuab luam ntawv tau pom ntau yam kev lag luam nce qib hauv lub xyoo, ntxiv dag zog rau lawv cov kev ua tau zoo thiab muaj peev xwm. Cov kev nce qib no tau ua rau kev txhim kho hauv cov haujlwm tseem ceeb xws li luam tawm ceev, xim raug, automation, thiab ib puag ncig kev ruaj ntseg.

Print Speed ​​thiab Productivity

Nrog rau kev nce qib hauv cov tshuab luam ntawv offset, luam ntawv ceev tau nce siab heev. Cov tshuab niaj hnub tuaj yeem tsim ntau txhiab tus luam tawm ib teev, txo lub sijhawm ntau lawm. Qhov kev nrawm nrawm no tso cai rau kev tsim khoom ntau dua thiab nrawm dua lub sijhawm, ua rau offset luam ntawv yog qhov kev xaiv zoo tshaj plaws rau kev luam ntawv loj.

Xim raug

Kev nce qib hauv kev tswj cov xim thiab kev tswj hwm hauv computer tau ua kom cov xim raug zoo dua hauv kev luam ntawv offset. Sophisticated xim profileing cov tswv yim, spectrophotometers, thiab xim calibration software pab kom meej tswj cov xim luam tawm, kom ntseeg tau zoo nyob rau hauv ntau yam luam tawm.

Automation thiab Precision

Automation tau ua ib qho tseem ceeb tsav tsheb tom qab kev ua haujlwm ntawm offset tshuab luam ntawv. Cov tshuab computer tswj tau ua cov haujlwm xws li kev thauj khoom phaj, kev faib tus lej, thiab kev sau npe, txo qis tib neeg kev ua yuam kev thiab ua kom qhov tseeb tag nrho. Qhov no automation kuj tso cai rau kev teeb tsa yooj yim dua thiab hloov txoj haujlwm sai dua, ntxiv dag zog rau kev tsim khoom.

Environmental Sustainability

Offset luam ntawv tau ua qhov tseem ceeb hauv kev ua tus phooj ywg ib puag ncig. Kev siv cov kua txiv hmab txiv ntoo thiab zaub-raws li inks tau hloov cov tshuaj roj av-raws li inks, txo kev cuam tshuam ib puag ncig ntawm kev luam ntawv. Tsis tas li ntawd, kev nce qib hauv kev rov ua dua number case thiab kev siv cov txheej txheem luam ntawv tsis muaj dej tsis zoo tau txo qis kev siv cov peev txheej thiab tsim cov khoom pov tseg.

Cov ntsiab lus

Offset tshuab luam ntawv siv cov kev tshawb fawb tom qab hloov tus cwj mem, daim duab phaj, thiab kev tswj xim kom xa cov ntawv luam tawm zoo. Kev siv cov ntawv luam ntawv, cov txheej txheem offset, thiab cov thev naus laus zis tau hloov pauv kev lag luam luam ntawv. Nrog kev nce qib hauv kev nrawm, xim raug, automation, thiab kev ruaj ntseg, offset printing tseem yog ib qho tseem ceeb thiab cov txheej txheem luam ntawv. Txawm hais tias nws yog tsim cov ntawv xov xwm, ntawv xov xwm, phau ntawv, lossis cov khoom ntim, cov tshuab luam ntawv offset tseem ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li cov kev xav tau ntawm ntau yam kev lag luam.
