Cov ntawv xov xwm fais offset siv ntau hom kev hloov, tiam sis hauv cov ntsiab lus, lawv tuaj yeem muab faib ua peb hom ntawv: kev xa ncaj qha, hloov tsheb, thiab hloov mus rau lwm tus.
Nyob rau hauv xyoo tas los, qhov ceev ntawm printing presses tau nce, thiab qhov ceev ntawm sheetfed offset presses tau mus txog 16,000 nplooj ntawv ib teev los yog siab dua. Txawm hais tias txoj kev hloov ntawm cov ntaub ntawv uas yog siv dav yog cov yam ntxwv ntawm daim ntawv hloov ntaub ntawv, nws tuaj yeem ua raws li cov kev cai ntawm kev ua luam siab. Txawm li cas los xij, txoj kev pauv no kuj yog ib qhov kev sib hais ntawm cov neeg tuaj yeem, thiab daim ntawv uas tau muab tso ua ke tseem pauv mus rau lub tswv yim khawm ob zaug 叼 Daim ntawv xuas phom, ceev ceev qhov kev luam ntawv, qhov loj tshaj qhov kev puas tsuaj rau lub tshuab, qhov kev tsis pom zoo, kev cuam tshuam ntawm cov ntaub ntawv pov thawj, qhov no hindering cov kev txhim kho ntxiv ntawm kev luam ntawv, thiab cov luam ntawv nce mus rau ib cov degree. Tom qab kawm tiav, vim muaj kev txwv ntawm kev tsim cov cuab yeej thiab cov laj thawj txheej txheem xws li kev sib dhos yuam kev thiab kev co, yuav muaj qhov yuam kev thiab yuav cuam tshuam qhov tseeb ntawm overprinting.
Rau qhov kawg no, nyob rau qee qhov kev kub ceev ceev, qhov kawg ntawm qhov ntawv tso rau ntawm daim ntawv tso rau ntawm lub tswv yim kheej kheej, xws li txoj cai txiav txim zaum kawg uas muab tso rau ntawm lub hneev taw ntawm lub tswv yim es tsis yog ntawm daim ntawv qhia. Tom qab daim ntawv hla dhau kev cai ua ntej thiab cov txheej txheem ntawm cov ntawv sau rau sab nraud, qhov kev khiav ceev nce ntawm pes tsawg mus txog 25% ntawm txoj kab ceev ntawm cov menyuam qhov chaw, thiab daim ntawv raug thawb nias ntawm lub hauv ntej sib deev ntawm nruas rau qhov chaw. Hom kev hloov no hu ua transcendental transfers.
Los ntawm kev siv cov ntaub ntawv xa mus rau lwm tus, hloov sijhawm ntawm daim ntawv ntawm txoj cai yuav ua kom ntau npaum li tsawg tau, thiab daim ntawv ceev nrooj ntawm kev tawm suab ntawm cov ntawv reciprocating accelerates daim ntawv tshaj qhov ceev ceev ntawm cov menyuam qhov chaw, thaum kawg locates ntawm lub nruas, thiab tom qab ntawd ces tus cylinder yog smashed. sau. Qhov no tshem tawm qhov teeb meem ntawm kev rhuav tshem cov ntawv sau cov lus tseeb thaum lub sij hawm hloov cov txheej txheem. Txoj kev xa cov ntawv xa no ua rau qhov tsis muaj tseeb thiab tsis ncaj nraim mus, thiab yog qhov zoo rau kev ceev ntawm kev luam. Nws muaj qhov zoo li nram qab no:
1 Piv nrog rau txoj kev hloov ntawm txoj kev tuaj yeem, daim ntawv tau txo kev hloov mechanism, uas yog kev cog lus hauv kev ua qauv thiab muaj kev txo qis ntawm cov ntawv xa tawm.
