Yog li ntawd, cov tshuab luam ntawv loj loj yuav pib tsim cov xim 8-10 -j xim uas yog siv ob npaug ntawm ob lub luam ntawv hauv ib lub xyoos lossis ob xyoos.
Ncig saib duab
Niaj hnub no, ntau lub chaw lag luam yog muag offset presses nrog cov peev xwm saib duab uas ncaj qha rau cov duab. Lub Speedmaster DI 74 hom 4 luam ntawv cov ntaub ntawv ua tiav ntau yam ntawm siab tsis siv neeg, ncaj zog luam.
Xim tswj thiab lithographic offset xovxwm
Lithographic printers uas muaj peev xwm saib xyuas ncaj nraim yog qhov tsim nyog rau ICC cov qauv thiab cov kev tswj xim xim hauj lwm hauv kev lag luam luam. Piv txwv, tus 74 Karat xovxwm tau sau ib daim ntawv ntawm tib tus naj npawb ntawm ICC cov ntaub ntawv tom qab nkag mus rau qhov kev tsim nyog. Piv txwv, cov ntaub ntawv pov thawj uas luam tawm nrog SWOP number case yuav siv los luam tawm ntau tshaj tom qab sib xyaw xim: Cov ntaub ntawv offset raws li cov qauv siv Euro yuav siv tau rau lwm cov ntawv luam tawm tom qab xim sib txawv. Tsis tas li ntawd, tus 74 Karat xovxwm tau siv nrog ntau cov cuab yeej pov thawj nrog cov ntaub ntawv tsim nyog ICC. Raws li cov kev tswj xim xim siv ntxiv rau cov menyuam kawm ntawv ua kom tiav, cov kev tswj tshiab xws li CPC 24 tau tsim los ntawm Heidelberg yuav ua si lub luag haujlwm tseem ceeb hauv kev tswj xyuas cov ntawv xovxwm. CPC 24 relies rau ntawm ib daim ntawv teev cov ntawv sau cij / xim ncoo los txheeb xyuas tag nrho cov ntawv tsis tas siv ntau hom xim. Nyob rau hauv txoj kev no, CIE L * a * b * tus nqi ntsuas los ntawm cov duab ntawm daim duab yuav muab piv nrog rau CIE L * a * b * tus nqi. Ces qhov kev hloov kho tau ua kom haum rau CMYK qhov tseem ceeb rau qhov yuav tsum tau CIE L * a * b * qhov tseem ceeb. Nrog rau kev siv xim ntawm cov xim thiab cov ntaub ntawv ICC (es tsis yog densitometers) hauv cov ntawv sau ua cov qauv, cov xim tsom tswj cov kev cai yuav raug tshem tawm. Kev siv cov cuab yeej xim thaij hauv cov ntawv ua haujlwm sheetfed yuav muaj feem xyuam rau ntawm cov nplooj ntawv. Hauv kev ua haujlwm ntawm cov pov thawj los ntawm qhov sib txawv ntawm cov pov thawj, cov pov thawj yog xam cov txuj ci, thiab cov neeg ua hauj lwm cov tshuab luam ntawv qis tshaj li kev xuas ntim ntawm cov xoom txheej ntawm cov xovxwm kom tau zoo tib yam. Nrog ColorSync xim tswj workflow, lub lithographic xovxwm yuav pib dua thiab calibrates cov ntaub ntawv raws li pre-hais xim xim profiles. Muaj tsawg dua thiab tsawg dua cov neeg siv cov qauv kev sib piv ntawm cov qauv ua haujlwm, uas yuav muaj tshwm sim los ntawm kev tshem tawm cov kev daws teeb meem analog. Cov ntaubntawv povthawj siv digital, vim yog qhov tseeb ntawm lub tshuab luam ntawv, muaj peev xwm ua tau cov ntaub ntawv pov thawj ua haujlwm tsis pub dhau lub sijhawm ua haujlwm, uas yuav ua rau txoj kev txhawb nqa thiab kev siv computer cov phaj ua haujlwm.
Lub luag haujlwm ntawm CIP3 technology
CIP3 technology (kev koom ua ke ntawm prepress, luam ntawv thiab postpress operations) yuav sai sai no muaj feem cuam tshuam rau hauv cov ntawv luam tawm ntawv. Cov CIP3 tshuab muaj cov CIP3 Luam Ntawv Hom Ntawv (PPF) los nkag cov haujlwm ua haujlwm rau hauv cov ntaub ntawv rau kev npaj rau kev koom ua ke ntawm cov ntawv sau, cov ntawv sau thiab postpress. Piv txwv, daim ntawv npaj ua hauj lwm prepress yuav khaws cov ntaub ntawv rau ntawm daim ntawv loj, muab nyiaj npaum li cas, kev siv folding, thiab kev ua tiav. Raws li txoj hauj lwm hla hauv CIP3 workflow, lub tshuab uas tau tshaj PPF hom ntawv yuav tau kho cov chaw raws li cov ntaub ntawv khaws tseg rau hauv cov ntawv ua haujlwm PPF. Muaj ntau cov neeg ua lag luam ntawm cov khoom siv ua khoom kho, cov khoom siv luam ntawv thiab cov khoom tiav tau pom zoo los txais yuav tus txheej txheem PPF. Tab sis kev tshawb nrhiav tsis ntev los no los ntawm American Association ntawm Printing thiab Publishing Technology Cov neeg qhia tau pom tias cov neeg tuaj yeem yuav cov tshiab xovxwm tsis tshua xav txog tias cov xovxwm tau siv CIP3 technology. Feem ntau cov neeg muas zaub npaj yuav hloov tag nrho cov cuab yeej siv khoom. Yog li ntawd, CIP3 cov khoom siv tshuab yuav siv sij hawm me ntsis kom muaj kev cuam tshuam. Txawm li cas los xij, hauv 10 lub xyoos tom ntej no, cov txheej txheem siv cov ntawv CIP3 uas siv lub tshuab luam ntawv yuav raug txhawb thiab siv.
Saib rau yav tom ntej
Los ntawm kev sib hloov tam sim no, sheetfed offset luam ntawv yog txav hauv cov lus qhia ntau, cov phiaj ntaus ntawv nrog ntau hom khoom siv thiab khoom muag. Ib qho ntawm txoj kev loj hlob ntawm kev loj hlob yog ua kom cov qib ntawm automation thiab luv kom npaj lub sij hawm rau kev hloov. Cov xovxwm tsis yooj yim yog yooj yim khiav lag luam thiab yuav tsum ua haujlwm tsawg dua. Qhov tseeb, qhov tseeb offset presses nrog cov peev duab peev duab tau minimised kev cob qhia cov cai rau kev khiav haujlwm haujlwm. Vim tias cov tswv ntiav mus txuas ntxiv mus ntsib cov neeg tsis paub ntaub ntawv cov neeg ua haujlwm, cov xovxwm tseem tseem pom tau los ntawm tib neeg kev pabcuam. Cov kev tswj xim xim yeem yuav nce siab siv rau hauv cov phiaj xwm txheej. Peb tseem yuav pom ntau thiab ntau cov chaw luam ntawv ua cov pov thawj raws li cov yam ntxwv ntawm cov xovxwm luam, tsis yog rigidly cia cov xovxwm tau raws li cov kev cai ntawm cov pov thawj. Muaj tsis paub tias cov ntawv xovxwm no yuav tsis muaj qhov sib piv rau digital presses nyob rau hauv lub khw muag khoom luv luv (tshwj xeeb tshaj yog luam tawm) tsib xyoos tom ntej no. Txawm li cas los xij, lithographic presses muab ntau dua li cov xovxwm hauv kev siv ntau hom substrates, txheej cov ntaub ntawv, thiab cov xim xim hauv qhov chaw.
Feem ntau, lithographic offset presses tseem yuav yog cov khoom siv hloov lag luam qis dua hauv kev lag luam luam tom qab peb nkag mus hauv lub xyoo pua 21st.
