1. Kev Txhim Kho Kev Taw Qhia ntawm Offset Printing Technology
Tam sim no, cov ntsiab lus tseem ceeb thoob ntiaj teb offset luam ntawv suav nrog ncaj qha - mus rau - phaj tshuab, tshuab luam ntawv ncaj qha, kab rov tav - thev naus laus zis luam ntawv dawb, thiab zaus ntsuas kev ntsuas tshuab. Feem ntau cov ntawv txawv teb chaws- pub ntau xim offset printing presses ntiav cov chaw taws teeb tswj ink tswj, tsis siv neeg phaj loading, thiab tsis siv neeg sau npe khoom siv, tswj thiab kuaj xyuas qhov tsis raug thoob plaws hauv tag nrho cov txheej txheem tsim khoom. Kev txhim kho hauv tsev tau pib tom qab, thiab xav tau kev siv zog ntau dua hauv kev tshawb fawb thiab kev txhim kho ntawm - tiam tom ntej integrated multicolor offset printing presses. Tsis tas li ntawd, qhov zoo ntawm cov khoom siv luam ntawv hauv tsev (daim ntawv, number case, cov ntaub ntawv photosensitive, thiab daim pam) xav tau kev txhim kho.
2. Txoj Kev Txhim Kho Ntawm Flexographic Printing Technology
Ua raws li kev kos npe ntawm Monte Carlo Convention hauv 1995, emission controls on CFCs (chlorofluorocarbons) tau dhau los ua nruj, thiab cov kuab tshuaj xws li trichloroethane thiab tetrafluoroethylene kuj tau txwv. Txhawm rau kom flexographic luam ntawv ua tau raws li qhov yuav tsum tau ua ntawm ib puag ncig, muaj ob txoj hauv kev txhim kho: ib qho yog kev tsim cov phaj tshiab ntawm ib puag ncig tus phooj ywg- ntxuav cov kuab tshuaj, thiab lwm qhov yog kev txhim kho, kev tsim khoom, thiab kev siv dej siv tau- cov phaj flexographic tsim tau. Nyob rau tib lub sijhawm, cov ntawv luam ntawv nyias nyias kuj tseem yuav yog txoj kev txhim kho rau kev luam ntawv flexographic.
3. Txoj Kev Txhim Kho Ntawm Gravure Printing Technology
Gravure luam ntawv cov cuab yeej xav tau kev nqis peev tseem ceeb thiab muaj phaj siab- ua cov nqi, ua rau nws tsuas yog siv tau ntev - khiav cov khoom. Kev siv gravure inks kuj raug txwv vim muaj cov tshuaj lom. Yog tias cov kev tsis txaus no tuaj yeem daws tau, gravure printing yuav pom kev loj hlob tseem ceeb. Nyob rau hauv xyoo tas los no, kev nce qib hauv gravure luam ntawv phaj thev naus laus zis tau txo lub sijhawm npaj ua ntej, txhim kho nws txoj kev sib tw hauv nruab nrab thiab luv - khiav lag luam ntau lawm. Kev txhim kho yav tom ntej ntawm gravure luam ntawv yuav tsum tsom mus rau: tag nrho automated gravure lub tog raj kheej electroplating; daim ntawv thov ntawm filmless electronic engraving tshuab; photopolymer nyias yob gravure tshuab thiab kev txhim kho ntawm wraparound gravure daim hlau; digital ceev pov thawj; thiab kev txhim kho ntawm gravure printing presses rau ntau- lub hom phiaj, ntau-xim, siab- ceev, automated, interconnected, thiab ib puag ncig tus phooj ywg cov lus qhia; ua tiav dej-raws li gravure number case luam ntawv thaum tswj tau cov ntsiab lus ntawm cov kuab tshuaj residual ntawm cov kuab tshuaj{11}}raws li inks.
