1 Taw qhia
Qhov zoo tshaj ntawm kev luam ntawv luam tawm yog kev ntsuam xyuas los ntawm ob yam: duab xim tu tub tu kiv thiab suab nrov tu theem siab. Cov qib kev sib hloov ntawm lub suab yog nyob ntawm seb muaj pes tsawg lub hauv cheeb tsam hauv chav kawm thiab cov dots whose dots hloov tsis tu ncua ntawm me me mus rau loj. Qhov ntau ntawm cov dots nyob rau hauv cheeb tsam hauv chav kawm, ntau ntau cov npav nyob rau hauv daim ntawv cheeb tsam, thiab qhov tseeb luam ntawm cov ntawv luam tawm. Qhov ntau dua cov degree, lub richer qib, qhov ntau tseeb qhov xim; qhov ntau ntawm cov kev hloov nyob rau hauv cov teev, qhov zoo dua qhov kev ua tau zoo ntawm cov qib theem thiab qhov muag heev nws zoo nkaus li. Hauv cov txheej txheem luam ntawv, cov tib neeg tswj cov teeb meem hauv cov cheeb tsam tsev kawm ntawv los ntawm kev hloov cov naj npawb ntawm cov vijtsam. Qhov ntau dua cov npo ntawm cov npo, qhov ntau ntawm cov dots nyob rau hauv cheeb tsam chav kawm, thiab me me qhov loj ntawm cov dots reproduced. Tam sim no, tus naj npawb ntawm feem ntau siv coated ntawv kab yog nruab nrab ntawm 150 thiab 175 lpi. Txawm li cas los xij, nrog kev txhim kho cov neeg zoo siab, qhov kev sau ua ntej qhov teeb meem no tsis tuaj yeem ua raws li tib neeg cov kev xav tau. Yog li ntawd, ntau lub tuam txhab luam ntawv siv high-speed cable technology kom tau luam tawm nrog ntau cov khaubncaws sab nraud povtseg, txhais ntau dua, ntau xim, thiab luam kev txig mus rau qhov qub, kom tau raws li cov kev xav tau ntawm high-end albums thiab ntim ntim nto moo.
Raws li ib yam tseem ceeb ntawm Hefei Sino-German Printing Training Center thiab German Gaobao Company luam ntawv seminar thiab Gaobao khoom exhibition tuav hauv Hefei, nws yog kev kuaj ntawv ntawm 300 cov khoom luam tawm hauv network. Peb ua tiav kev sib piv luam tawm ntawm 300lpi luam tawm thiab 150lpi luam tawm nrog kev pab los ntawm KBA cov kws kho.
2 kev tshuaj ntsuam xyuas
Nws paub zoo tias dot enlargement nyob rau hauv cov txheej txheem luam ntawv (nrog rau cov neeg kho tshuab dot thiab optical dot enlargement) yog ib qho kev tsis haum xeeb uas luam tawm los ntawm cov duab xa tawm tau pom los ntawm kev ceev. Qhov loj ntawm qhov txiaj ntsig ntawm qhov kev nce nqi yog feem ntau ntawm qhov sib npaug ntawm qhov ntsuas ntawm qhov ntawm cov cheeb tsam hauv chav kawm. Rau cov nqe lus teev tib, qhov sib npaug ntawm 300 lpi dot yog loj tshaj qhov sib npaug ntawm qhov ntsuas ntawm 150 lpi dot. Uas yog hais, tus dot enlargement tus nqi ntawm 300 lpi yog loj tshaj qhov dot enlargement tus nqi ntawm 150 lpi. Hauv kev pom ntawm qhov no, peb yuav kuaj thiab tsim ib qho kev tsim tawm tus cwj pwm ua rau kev tso zis thaum cov zis luam tawm.
Tus 300 lpi 2% dot inch yog li 11,6 μm, uas yog yuav luag tib yam li txoj kab uas hla ntawm cov hmoov av. Yog li ntawd, cov plua plav ntawm lub khob ntawm cov ntawv luam tawm los yog cov yeeb yaj kiab yog yooj yim kom raug, ua tus hu ua "pseudo-mesh", uas cuam tshuam nrog luam ntawv. Qhov kev lag luam li qub, yog li peb yuav tsum nruj me ntsis kom cov txheej txheem tsis muaj paug nyob rau hauv PS version ntawm txoj kev ziab. Tsis tas li ntawd, PS lub phaj yuav tsum tau tsim nrog PS phaj tsim tshuab thiab txoj kev txhim kho yuav tsum ruaj khov.
Kev xaiv cov ntaub ntawv sib tw kuj tseem nruj heev. Peb yuav tsum ua tib zoo xav txog cov yam ntxwv ntawm 300lpi ntawm cov ntawv sau thiab xaiv cov ntawv luam tawm kev tsim nyog.
Nyob hauv kev luam ntawv, cov neeg ua haujlwm luam tawm yuav tsum muaj cov kev txawj zoo thiab kev ua haujlwm zoo, los ua "peb txoj haujlwm", thiab kom muaj tus cwj pwm zoo thiab ntxuav nyiaj seem hauv cov txheej txheem luam ntawv.

4 txoj kev xeem
(1) Thawj cov khoom
Peb siv cov ntawv sau los ntawm KBA hauv tebchaws Yelemees. Cov phau ntawv no tau khaws cia rau CD hauv eps, rau tag nrho cov duab yim, txhua tus uas muaj duab ntim ntawm 83MB. Peb tau xaiv peb cov duab sawv cev ua cov qauv kev sim, uas yog xim tawv dluab, cov dluab caw, thiab cov rooj tog txaj. Peb tsis ua dab tsi nrog cov qauv, lawv tuaj ncaj qha mus rau pawg Pagemaker, tom qab ntawd hu ua cov zis ua tus cwj pwm hauv Delta qhov chaw ua hauj lwm, thiab thaum kawg tawm zaj duab xis ntawm Hercules. Vim tias cov dluab tsis tuaj yeem ua tiav ntawm 300lpi thiab 150lpi rau tib nplooj ntawv, peb yuav tsim tawm 300lpi thiab 150lpi duab cais, thiab mam li muab cov nplooj ntawv qhia txog 300lpi thiab 150lpi rau tib qhov teeb tsa los ntawm kev ceev xwm txheej.
(2) Cov ntawv luam ntawm lub hnub
Peb tau ua ib qho kev soj ntsuam ua ntej luam tawm 300lpi cov dots, nrog rau cov kev daws teeb meem PS thiab cov kev tshawb nrhiav rau lub sij hawm raug. Yog parsing zog ntawm PS version tsis tuaj yeem qhov tsawg kawg nkaus dot, nws yog obviously tsis txaus siab. Peb siv UGRA1982 print proofing sawb thiab siv cov txheej txheem xeem tau los kuaj qhov Jindongyang pictogram PS version. Tom qab tsim lub PS phaj raws li kev loj hlob zoo, saib cov luam ntawm yin thiab yang lub voj voog ntawm UGRA1982 luam ntawv pov thawj tswj kev sawb rau kev sojntsuam cov PS version ntawm qhov kev daws teeb meem (raws li yam tsawg kawg 505, qhov kev tsim tawm meej). thiab PS version yog txiav txim raws li. Qhov kev daws teeb meem yog 6 μm. Raws li cov lus teb, 100% ntawm cov dots ntawm 300 tawm lub lpi luam muaj ib txoj kab uas hla ntawm 83 μm, thiab 2% ntawm cov dots muaj ib lub cheeb ntawm 11.6 μm. Nws tuaj yeem hais tau tias PS daim phaj tiav txaus siab rau kev xeem ntawv.
Cia peb saib lub sijhawm zoo. Ntawm no peb tsuas yog xav txog kev ziab ntawm cov kab mob 300lpi. Yog tias 2% teev thiab 98% dot ntawm 300 lpi kab yeej qhia meej meej, 2% dot thiab 98% dot ntawm 150 lpi kab ntawv yuav tsum tau meej meej reproduced. Peb kuj siv UGRA1982 daim ntawv pov thawj tiv thaiv kev tswj kom nrhiav tau lub sij hawm tsim nyog raug raws li kev tshee tshee. Nyob rau hauv cov txheej txheem no peb tau taug kev ib qhov kev pom zoo. Peb ua ntej ntxuav lub khob ntawm lub phaj nrog iav, txhuam cov kab xo 300lpi nrog cawv (peb ntsuas qhov siab tshaj plaws ntawm qhov sib npaug ntawm qhov teeb meem sib txuas nrog tus ciav hlau txuas mus rau 5.6) thiab ntxuav lub PS phaj nrog huv qhov ncauj, ces tso nrog 450 Tuag, 380 tawm tsam, 315 tus nphoo raug nphav raug lub phaj (tsis tas siv cov txheej txheem ntxiv), tom qab kev loj hlob tau pom: ntau dua 90% ntawm cov lus tseeb ntawm qhov kev tshwm sim tshwm sim nrog 450 raug ntaus, tsawg dua 10 % Cov teev tau poob lawm; ntau tshaj 80% ntawm cov dots ntawm lub phaj zoo nrog 365 raug tus kabmob sib tsoo thiab 315 raug mob raug poob lawm, thiab cov teev hauv qab 5% poob. Obviously, xws li ib lub phaj luam ntawv tsis tuaj yeem ua raws li cov ntawv luam tawm, tsuas yog raws li hauv qab no: qhov ci ci ntawm cov txheej poob lawm, thiab lub suab tsaus nti yuav tshwm sim tsis tsim nyog dlhau hauv siab ntawm kev luam ntawv siab. Yog li ntawd, peb yuav tsum tau luv lub sij hawm raug ntawm lub phaj thiab txo qhov siab tshaj plaws qhov ceev ntawm zaj duab xis.
Raws li ib tug German colleague, tsuav yog qhov siab tshaj plaws ntawm daim duab yeeb yaj kiab yog saum toj kawg nkaus 2.4, tus thawj hauv Internet yuav xa txhua nrho mus rau PS version. Yog li, peb hloov tus cwj pwm ntawm tus cwj pwm, teeb qhov khoom ntau tshaj 3.4, thiab tso zis ntau ntxiv rau 300lpi teeb liab pluaj zaj duab xis rau kev kuaj, thiab mam li ntsuas cov ntawv xov xwm nrog 250 phom tua, 300 tawm raug dua, Tom qab kev loj hlob, nws pom tau hais tias 90% ntawm cov dots nyob rau hauv lub phaj zoo nrog 300 phom zoo, 380 raug tus kabmob, thiab 250 raug tus kabmob yeej pom tseeb, thiab tsuas yog qhov zoo version ntawm lub sijhawm 250 Cov neeg ntaus tau tibsi Cov lus saum toj 5% ntawm qhov chaw tshaj tawm tseem khaws cia.
(3) Cov txheej txheem luam ntawv
Yuav kom ua tiav qhov kev xav tau luam tawm, peb hloov lub thawv cua tshiab tshiab nrog kev hloov kev kawm tshwj xeeb thiab tshwj xeeb lub hnab ua ntej luam ntawv. Qhov kev luam ntawv tau ua tiav los ntawm Mr. Hasse, tus kws tshaj lij tshuab luam ntawv los ntawm KBA hauv lub teb chaws Yelemees, thiab tus me nyuam caj qaum ntawm Sino-German Printing Training Center. Thaum lub sij hawm luam ntawv, Mr Hasse ua rau cov neeg Suav pom zoo nrog rau cov neeg German. Nws ua tib zoo kuaj thiab muab piv nrog cov qauv siv tau kom tau qhov zoo tshaj plaws tau luam tawm. Hauv siab tshaj plaws luam ntawv, nws mus txog 10,000 nplooj / teev.
5 Ntsiab lus tau zoo
Los ntawm kev soj ntsuam cov duab sib txawv tom qab luam ntawv, peb pom tias qhov txawv ntawm 300lpi prints thiab 150lpi prints yog tseem cuab kev, feem ntau nyob rau hauv cov nram qab no.
(1) Lub xub ntiag los yog tsis tuaj yeem mob pob
Thaum peb saib cov duab luam tawm nyob ze, peb pom tias qhov chaw kaj thiab qhov nruab nrab ntawm 150-vijtsam duab tau pom ib qho chaw ntawm lub ntsej muag uas pom tau yooj yim los ntawm tib neeg lub qhov muag, ua rau pom kev ntxhib thiab xim tsis muaj luster, thaum lub sijhawm sau ntawm 300 lpi Kuv pom tsis tau lub pob zeb ntawm nws. Qhov no qhov nqaij ntawd yog ua los ntawm ntau tshaj ntawm cov ntawv teev cov nplooj ntawv, thiab lub vas feem ntau yog 2 txog 4 npaug qhov ntev ntawm cov teev. 150 lpi dot ntev yog 167 μm (1 × 2.54 × 10000/150), qhov ntawd yog, txoj kab uas hla ntawm qhov sawv ntawm 334 μm thiab 668 μm. Thaum qhov deb ntawm qhov ci me ntsis yog me me, lub Rose chaw yuav pom tseeb thaum lub qhov deb yog heev ci. Thaum loj, lub Rose me ntsis yuav pom meej meej. Thaum qhov deb ntawm qhov chaw qaim yog loj, qhov loj me ntawm lub pob zeb yog nyob rau hauv cov kev txwv ntawm kev daws teeb meem ntawm tib neeg lub qhov muag, thiab cov neeg tsis pom qhov phenomenon ntawm Rose me ntsis. Qhov ntev ntawm 300 lpi dot yog 83 μm, thiab txoj kab uas hla ntawm lub pob ntseg kuj yog txo kom 167 μm mus rau 334 μm. Vim nws txoj kab uas hla me me, txawm nyob ntawm qhov chaw ze me, peb tuaj yeem tsis pom qhov tshwm sim ntawm cov quav hniav.
(2) Lub meej ntawm qhov teeb meem luam tawm
Cov duab clarity ntawm 300lpi prints yog zoo dua li ntawm 150lpi prints, vim qhov teeb meem loj ntawm 300lpi prints tsuas yog ib lub hlis twg ntawm qhov loj ntawm 150lpi luam dots, uas yog, cov ntsiab lus originally reproduced los ntawm ib tug Dot yog tam sim no muaj li ntawm plaub me dots yog cuab dua ua rau sharpness li ntawm cov duab txheej Area, uas nyob rau hauv lem kho txhim lub sharpness ntawm daim duab.
(3) Xim softness
Qhov kev ntsuam xyuas qhov dav hlau amplitude yog tus hloov qhov hloov ntawm qhov qub thiab qhov hloov ntawm qhov tob tob los ntawm kev hloov ntawm qhov loj me me. Hauv daim teb xim tam sim no, peb feem ntau luam theej rau ntawm qhov kev daws teebmeem ntawm 300 lpi, thiab tso zis rau ntawm cov dluab nrog ib tug 150 lpi ntawm cov kab dai. Uas yog hais tias, thawj dot replicates cov ntaub ntawv xim plaub ntawm pixels ingested. Feem ntau, grayscale qhov tseem ceeb ntawm cov plaub pixels sib txawv, tab sis lub computer ignores plaub pixels thaum cov teev yog generated. Qhov sib txawv ntawm qhov grey sib npaug raws li tus nqi txheeb ntawm qhov ib nrab ntawm plaub lub pixels. Qhov no yog lub ntsiab tseem ceeb yog vim li cas peb xav tias cov kabmob qis qis tsis zoo li cov khoom qub. Yog tias peb siv cov xaim tooj 300lpi uas yog tus lej tso zis, uas yog hais tias, txhua cov ntaub ntawv tseem ceeb ntawm cov ntaub ntawv xim ntawm ib lub pixel, cov thawj cov nplua grey yuav luam tau ib los ntawm ib qho, thiab cov xim uas ua tau yog softer thiab nyuaj.
(4) Theem kev ua tau zoo ntawm cov ntawv luam tawm
Cov lus tshaj tawm ntawm cov ntawv luam tawm yog qhov kev hloov ntawm qhov kev hloov ntawm qhov hloov maj mam, uas yog, qhov kev sib txuas lus yog raws li kev daws teeb meem ntawm thawj daim duab, tiam sis raug cuam tshuam los ntawm lwm yam xws li cov xov tooj ntawm cov npo. Vim tias thaum cov dluab tso tawm nrog 150lpi ntawm dai nets, nws lub laser precision yog 2400dpi (150 × 16, ntawm cov tshuaj 50 sawv cev ntawm cov kab npo, 16 nruab nrab ntawm cov ntsiab lus square ntawm gray scale 256), thiab phototype tshuab muaj ib dai kab ntawm 300lpi. Thaum cov zauv tawm, nws lub laser precision yog 4800 dpi (300 × 16). Obviously, tus nab npawb ntawm 300 lpi dots nyob rau tib cheeb tsam yog 4 npaug ntawm 150 lpi dots, thiab qhov luaj li ntawm 300 tib tug lpi yog ib quarter ntawm qhov sib piv 150 lpi dot loj, yog li hais tias hierarchical qhia ntawm 300 LP luam tseem ceeb dua tuaj.
