4 cov txheej txheem luam ntawv tseem ceeb uas koj yuav tsum paub rau kev txiav txim, txwv tsis pub nws yuav teeb meem heev

Phau ntawv imposition yog ib qho tseem ceeb heev prepress txoj hauj lwm thiab ua hauj lwm raws li cov lus qhia tseem ceeb rau tag nrho cov txheej txheem ntau lawm. Txij li thaum phau ntawv tsim muaj ntau cov txheej txheem, cov txheej txheem sib txawv muaj qhov cuam tshuam rau kev luam ntawv zoo, kev ua tau zoo, thiab tus nqi. Ib txoj hauv kev tsim nyog tuaj yeem ua kom cov luam ntawv du. Kev tsim khoom tsis raug tuaj yeem ua rau muaj teeb meem tsis txaus ntseeg hauv kev tsim khoom, ua kom tiav tsis tuaj yeem lossis txawm xav tau rov ua haujlwm dua. Kab lus no yuav tshawb txog qhov cuam tshuam ntawm phau ntawv yuam kev ntawm cov txheej txheem luam ntawv sib txawv, vam tias yuav muab kev taw qhia rau cov phooj ywg.

Kev cuam tshuam ntawm kev cuam tshuam rau cov txheej txheem luam ntawv

Kev luam ntawv yog ib qho ntawm cov kauj ruam tseem ceeb tshaj plaws hauv kev tsim cov phau ntawv, thiab qhov zoo ntawm kev tsim khoom ncaj qha cuam tshuam rau cov nqi luam ntawv thiab kev ua haujlwm zoo. Feem ntau, yog tias qhov kev txiav txim kom muaj nuj nqis loj, qhov tseem ceeb yog muab rau kev siv daim ntawv -fed presses, yim- xim xovxwm, lossis txawm tias lub vev xaib xovxwm, txhua qhov muaj qhov sib txawv ntawm qhov yuav tsum tau ua, raws li tau tham hauv qab no.

Thaum siv ib daim ntawv - pub xovxwm, thawj kauj ruam yog los xyuas seb daim ntawv xaj loj puas tau raws li qhov yuav tsum tau ua. Thaum qhov teeb meem no yooj yim txaus siab, txoj kev folding yuav tsum tau txiav txim siab raws li tus naj npawb ntawm cov folds hauv cov txheej txheem tom qab. Feem ntau cov pa folding tshuab tsis tuaj yeem tuav folding tag nrho cov nplooj ntawv ntawm daim ntawv - pub presses thiab yuav tsum tau sib cais, xws li combining ob 16 - nplooj ntawv seem. Daim ntawv -fed presses qeeb dua dual - xovxwm tshuab, tab sis tag nrho cov kev ua tau zoo yog ob zaug ntawm ob zaug - xovxwm, txawm hais tias kev teeb tsa thiab kev sib dhos yuav siv sij hawm ntev dua, ua rau lawv haum rau kev txiav txim loj. Thaum qhov kev txiav txim kom muaj nuj nqis tshaj 10,000 daim ntawv luam thiab cov nplooj ntawv suav ntau tshaj 256 nplooj ntawv, siv daim ntawv -fed xovxwm tuaj yeem txiav txim siab. Qhov tsis zoo ntawm daim ntawv-fed presses yog tias kev tswj xim tsis zoo li dual- xovxwm tshuab, thiab tsis muaj cov cuab yeej tshwj xeeb thim rov qab, phau ntawv flipping tuaj yeem ua haujlwm hnyav.

Rau kev luam ntawv loj nrog ntau nplooj ntawv, yim - xim presses kuj tsim nyog. Yim- xim presses tuaj ntau hom; Los ntawm qhov kev xav pom, lawv tuaj yeem muab faib ua ib leeg gripper thiab ob chav gripper, nrog rau qhov chaw sib txawv. Rau cov ntawv tuav ib leeg, sab pem hauv ntej thiab sab nraub qaum tau luam tawm ib txhij, ua rau pem hauv ntej - rau - rov qab sau npe yooj yim rau kev tswj, tsuas yog tawm hauv ib qho xim strip ntawm phaj kawg. Txawm li cas los xij, luam tawm sab hauv qab ua ke muaj kev pheej hmoo xws li smudging hauv cov cheeb tsam ntawm cov number case hnyav, thiab qee cov qauv yuav tsum tau muab tso rau nruab nrab (suction txoj haujlwm). Yog tias tsis muab tso rau kom zoo, tom qab folding yuav ua rau cov nplooj ntawv tsis sib xws, ua rau hauv online stitching nyuaj, thiab tej zaum yuav xav tau cov ntaub ntawv pov tseg ntxiv kom ua tiav kev khi zoo. Rau ob chav gripper presses, kev tso cai yuav tsum tau khaws cov npoo ntawm gripper vim tias kev hloov pauv ntawm cov gripper feem ntau ua rau tsis raug, txo cov ntawv luam tawm. Yim- xim xovxwm yog tsim rau luam tawm ntau tshaj 8,000 daim ntawv, nrog rau nplooj ntawv hnyav ntawm 100–140g / m² thiab kev txiav txim uas tsis xav tau cov xim raug siab.

Web presses yog tus cwj pwm los ntawm kev kub ceev, inline folding, thiab ceev turnaround, ua rau lawv tsis haum rau kev txiav txim me me. Thaum tso cai rau lub vev xaib xovxwm, kev saib xyuas yuav tsum xub them rau grippers thiab xim tuav. Ntawm daim ntawv- pub presses, lub gripper thiab xim tuav feem ntau yog nyob rau txhua qhov kawg ntawm daim ntawv, nrog rau xim bar ntawm qhov kawg ntawm lub phaj. Nyob rau hauv lub web presses, lub gripper thiab xim tuav nyob rau hauv tib txoj hauj lwm, txuag ib co ntawv npoo. Lwm qhov kev txiav txim siab yog tias lub voj voog ntawm lub vev xaib raug kho, lub ntsiab lus ntawm daim ntawv loj (xws li gripper ntug) tsis tuaj yeem hloov kho thiab ib txwm muaj qhov ntev. Yog li ntawd, thaum txiav txim siab siv lub vev xaib xovxwm, thawj qhov kev txiav txim siab yuav tsum yog seb qhov ua tiav qhov loj npaum li cas ntawm cov xovxwm ncig. Txwv tsis pub, txawm tias kev ua tau zoo dua, daim ntawv ntug khib nyiab tuaj yeem ua rau tus nqi nce ntxiv, tshwj xeeb tshaj yog thaum muaj ntau qhov kev teeb tsa ntawm lub phaj kawg, ntxiv cov nqi ntawm phau ntawv pagination. Feem ntau, lub vev xaib xovxwm tsim nyog rau kev luam tawm ntau dua 30,000 daim ntawv, nrog rau cov ntawv hnyav ntawm 64-105g / m² rau cov nplooj ntawv sab hauv, muab qhov loj me me sib npaug ntawm txoj kev foldable imposition thiab cov cuab yeej siv siab tshaj plaws ntawm qhov ncig tsis pub tsawg dua 75%.

Thaum imposing, ntxiv rau kev xav txog cov yam ntxwv ntawm cov xovxwm saum toj no, kev saib xyuas yuav tsum tau them nyiaj kom tsis txhob tso cov duab nrog cov xim loj sib txawv hauv tib kem (sab saum toj thiab hauv qab txoj haujlwm); cov ntsiab lus uas yuav tsum tau sau npe meej, xws li cov ntawv hloov pauv me me, yuav tsum tau muab tso rau ze ntawm lub gripper; rau cov ntawv nyias nyias, xws li phau Vaj Lug Kub Npaiv Npaum uas hnyav dua 48g / m², tsis txhob yuam ntau nplooj ntawv ua ke, vim qhov no feem ntau ua rau ob daim ntawv, txo cov xovxwm, thiab kuj tseem yuav xav tau kev sib dhos ntxiv ua ntej folding vim qhov tsis sib xws.

Kev cuam tshuam ntawm Imposition rau Deg txheej txheem

Txawm hais tias cov phau ntawv thiab cov ntawv tsis tas yuav tsum muaj kev kho qhov muag zoo li ntim, qee qhov kev ua haujlwm zoo nkauj feem ntau yog ntxiv rau cov qauv tsim, uas ua rau muaj qhov sib txawv ntawm qhov kev txiav txim siab piv rau cov nplooj ntawv sab hauv. Rau cov nplooj ntawv sab hauv, nws yog qhov txaus los siv qhov loj ntawm cov xovxwm luam ntawv, thaum npog yuav tsum tau txiav txim siab ntau dua. Rau kev luam ntawv npog, nws yog qhov zoo tshaj plaws los siv plaub - qhib xovxwm, tsis muaj ntau daim ntawv luam ib daim ntawv; Txawm tias cov ntawv luam loj loj, feem ntau 4 daim ntawv tuaj yeem npaj tau. Rau cov khoom uas xav tau kev sau npe meej heev rau qee qhov kev kho mob saum npoo, nws yog qhov zoo tshaj plaws los npaj tsuas yog ib daim npog ntawm ib daim ntawv, tsis hais txog kev luam tawm, txwv tsis pub nws yuav ua rau muaj kev nyuaj ntawm cov txheej txheem tom ntej los yog ua rau lawv tsis yooj yim sua, xws li kub stamping, chaw UV, lossis embossing, uas txhua tus xav tau kev sib raug zoo nrog cov ntsiab lus luam tawm.

Feem ntau cov neeg ua haujlwm raug cai feem ntau ua rau tus kheej - rov qab daim hlau kom txuag tau cov ntaub ntawv, uas feem ntau yog tsim rau cov khoom uas tsis muaj kev kho deg. Nws tsis pom zoo kom ua qhov no rau cov npog lossis thaj chaw uas muaj kev kho mob saum npoo, vim tias nws yooj yim rau kev ua yuam kev thiab ua rau xim sib xws ntawm sab xub ntiag thiab sab nraub qaum.

Cov nplooj ntawv sab hauv kuj tuaj yeem raug kho saum npoo, yog li cov chaw uas xav tau kev kho mob yuav tsum tau muab tso rau ntawm tib sab kom ntau li ntau tau, txwv tsis pub muaj teeb meem tshwm sim. Piv txwv li, yog tias qhov chaw UV xav tau ntawm ob sab, sab nraub qaum yuav raug cuam tshuam vim tias daim ntawv tau dhau los ua kom qhuav los ntawm cov teeb ci ultraviolet lossis cov khoom siv cua sov ntawm sab xub ntiag, ua rau muaj kev nthuav dav thiab deformation, uas ua rau muaj kev nyuaj rau kev sau npe, thiab qee zaum, daim ntawv yuav curl thiab tsis tuaj yeem mus los ntawm cov xovxwm.

Ntxiv mus, rau cov khoom uas yuav tsum tau post- xovxwm tuag- txiav, qhov chaw rau kev luam ntawv pub nyiaj txawv ntawm cov khoom zoo tib yam, thiab nws yog ib qho tsim nyog yuav tsum tau xa mus rau qhov tsis muaj qhov tuag- txiav thiab tshuab luam ntawv los txiav txim qhov chaw raug.

** Kev cuam tshuam ntawm kev tso cai rau Folding thiab sib sau ua ke **

Kev tso cai tsuas yog ua haujlwm tshaj tawm - cov txheej txheem xovxwm. Hauv phau ntawv thiab cov ntawv luam tawm raws sijhawm, lub ntsiab lus tseem ceeb - cov txheej txheem xovxwm, tsis suav nrog kev kho saum npoo, yog folding thiab sib sau ua ke, nrog rau kev khi cov khoom tiav. Ib txhia kuj xa mus rau cov no li semi-cov khoom tiav thiab cov khoom tiav.

Cov txheej txheem folding feem ntau rau cov nplooj ntawv sab hauv suav nrog 4PP, 8PP, 12PP, 16PP, 24PP, 32PP, thiab lwm yam. Cov txheej txheem folding no feem ntau yog raws li daim ntawv tuab thiab seb lub pre-fold thiab post-fold dimensions poob nyob rau hauv cov khoom siv ntawm lub tshuab folding.

Rau feem ntau siv cov nplooj ntawv sab hauv xws li phau ntawv ntawv thiab cov ntawv coated, yog tias phau ntawv ntawv tshaj 120g / m² los yog coated ntawv tshaj 180g / m², siv 32PP imposition txoj kev yooj yim ua rau daim ntawv wrinkles.

Phau ntawv imposition feem ntau yog ua los ntawm cov tshuab bookmaking los yog bookmaking units ntawm zoo meej binding kab. Qee qhov ua tiav ntawm cov tshuab kev sib xyaw ua ke, qhov twg lub tshuab tsis siv neeg yuav tsum tau txiav txim siab seb puas muaj pes tsawg ntu tuaj yeem raug yuam ib zaug.

Piv txwv li, yog tias lub tshuab bookmaking tuaj yeem yuam 20 ntu ntawm ib lub sijhawm, thiab 16PP txoj cai yuav tsum muaj tag nrho ntawm 26 ntu, ob pawg yuav tsum raug yuam. Tom qab kuaj xyuas cov ntawv tuab thiab qhov ntev, yog tias siv 32PP txoj kev, tsuas yog 13 ntu yuav tsum tau txiav txim siab ib zaug, txhim kho kev ua haujlwm zoo.

Nyob rau hauv cov txheej txheem xws li sib sau ua ke, xov stitching, thiab eeb stitching, nws yog ib qho tsim nyog yuav tsum tau tso nyiaj rau cov npoo loj thiab me me los txhim kho kev tsim khoom. Thaum lub sij hawm txiav txim, qhov sib txawv ntxiv rau sab saum toj thiab hauv qab cov npoo yuav tsum tau ntxiv, feem ntau nrog qhov sib txawv tsawg kawg yog 5 hli, thiab nws yog qhov tsim nyog los ntsuas seb qhov hauv qab lossis sab saum toj yog loj dua. Daim ntawv thickness thiab tag nrho cov thickness ntawm phau ntawv yuav tsum tau txiav txim siab. Yog tias daim ntawv nyias dhau lawm, cov nplooj ntawv nrog cov suav loj yuav tsum tau sib sau ua ke. Piv txwv li, yog tias siv 70g / m² coated ntawv nrog tag nrho ntawm 40 seem, luam ntawv tsuas yog ua tau 16PP ib zaug. Sab hauv, nruab nrab, thiab sab nrauv tuaj yeem sib sau ua ke, tom qab ntawd ua tiav los ntawm cov ntawv tais ceev tseg (tib lub eeb stitch folding pab pawg), nrog cov xov stitching ua tiav ib ntu 48PP, txo tus naj npawb ntawm qhov kawg thiab ua rau tus txha nraub qaum ntau square thiab zoo nkauj. Yog tias muaj 4PP seem seem, lawv yuav tsum tau sau nrog lwm cov ntsiab lus tseem ceeb.

Ntau phau ntawv tsim fold- tawm nplooj ntawv nyob rau hauv cov nplooj ntawv sab hauv, uas tuaj yeem ua tau ib zaug - tawm los yog ob npaug - tawm. Yuav tsum tau saib xyuas tshwj xeeb hauv kev teeb tsa hais txog qhov loj thiab txoj kev folding. Qhov ntev ntawm cov nplooj ntawv txuas ntxiv yuav tsum yog me ntsis me dua qhov dav ntawm cov khoom tiav, feem ntau kom ntseeg tau tias du thiab txuas ntxiv ntawm cov quav - tawm nplooj ntawv.

Rooj vag-folded ob npaug - tawm nplooj ntawv uas yuav tsum tau xaws yog feem ntau nyuaj rau lis, thiab muaj ob txoj hauv kev tseem ceeb:

Thawj txoj kev yog 8PP rooj vag quav (yog tias cov khoom siv tsis tuaj yeem ua lub rooj vag folding, xav tau rov qab accordion quav hauv nruab nrab), muab tso rau ntawm txoj haujlwm. Tom qab tsim cov khoom tiav, txoj haujlwm no yuav kov yeej, uas yuav cuam tshuam me ntsis rau nws. Yog tias muaj tus ntoo khaub lig- nplooj duab nyob ze, txoj hauj lwm muab tso rau yuav cuam tshuam rau kev nthuav tawm ntawm tus ntoo khaub lig- nplooj.

Qhov thib ob txoj kev yog sewing raws lub quav. Txij li thaum lub rooj vag-fold quav- tawm tsis muaj cov npoo loj thiab me, cov qauv siv tsis tuaj yeem ntxig cov koob stitching. Nws feem ntau xav tau ob peb txheej ntawm 4PP cov ntaub ntawv pov tseg kom suav nrog, xaws los ntawm lawv, thiab tom qab ntawd tshem cov seem. Txoj kev no ua rau cov khoom kawg sturdier thiab ntau aesthetically pleasing tab sis nce nqi ntawm ob peb txheej txheem.

Cov kws tshaj lij tsim qauv tsim qauv siv tau tshwj xeeb 12PP version rau folding. Qhov 12PP version no txawv ntawm cov qauv 12PP folding thiab zoo ib yam li folding txoj kev ntawm tus qauv 16PP version. Txoj kev no yog qhov paub tab thiab zam cov txheej txheem tsis tsim nyog xws li suav nrog cov nplooj ntawv seem.

Kev cuam tshuam ntawm Layout ntawm Cov Txheej Txheem Kev Sib Txuas

Qhov tsim nyog folding thiab imposition layouts tuaj yeem daws teeb meem feem ntau hauv cov txheej txheem khi. Thaum lub eeb-stitching phau ntawv nrog ntau nplooj ntawv, lossis raws li tau hais los saum toj no, ntau nplooj ntawv sib koom ua ke rau kev xaws, nws yuav tsum tau txiav txim siab seb cov ntsiab lus ntawm ntug txiav tuaj yeem raug txiav tawm. Yog tias muaj kev pheej hmoo, kev teeb tsa prepress yuav tsum suav nrog kev hloov kho creep, nrog rau qhov kev ncua deb raws li qhov tuab ntawm kos npe lossis tag nrho phau ntawv.

Rau cov ntaub ntawv zoo meej khi thiab cov ntaub ntawv tawv tawv, cov nplaum nplaum ntawm cov ntawv kos npe yuav tsum tau muab tshem tawm kom tawm hauv qhov chaw. Lub hom phiaj ntawm kev tawm ntawm qhov sib txawv yog tso cai kom zoo dua adhesion rau cov kua nplaum. Rau tus ntoo khaub lig- nplooj ntawv duab nruab nrab ntawm daim npog lossis cov ntawv kawg thiab cov nplooj ntawv sab hauv, sib tshooj yuav tsum tau tsim kom tus ntoo khaub lig- nplooj tuaj yeem nthuav tau raug tom qab khi.

Lub npog ntawm ib phau ntawv zoo meej - khij yuav tsum muaj cov nplaum nplaum tshwj xeeb. Tus qauv yog tias daim npog yuav tsum qhwv ib nrab ntawm -cov ntawv tiav; txwv tsis pub, thaum lub sij hawm zoo tag nrho, cov nplaum tuaj yeem yooj yim hloov raws tus txha nraub qaum mus rau lub hau. Cov phau ntawv me me - loj zoo meej- khij cov phau ntawv feem ntau siv ob npaug - phau ntawv imposition txoj kev, thiab qhov sib nrug ntawm ob phau ntawv kuj yuav tsum tau ua tib zoo hloov kho raws li qhov tsis zoo ntawm cov khoom siv hauv qab kom tsis txhob muaj teeb meem txiav.

Kev tsim nyog yog qhov tseem ceeb rau kev luam ntawv ntau lawm, vim nws tuaj yeem txhim kho kev ua haujlwm zoo thaum txo cov nqi tsim khoom. Cov neeg ua haujlwm layout yuav tsum muaj kev nkag siab zoo txog tag nrho cov txheej txheem luam ntawv thiab cov khoom siv, thiab qhov zoo tshaj plaws, tus neeg mob siab rau yuav tsum saib xyuas kev tswj xyuas kom zoo thiab siv lub tshuab tshuaj xyuas.
