Master Cov 8 Lub Ntsiab Tseem Ceeb! Xauv qhov zais cia kom siab -Quality Digital Printing
Kev ua thawj coj
Txawm hais tias cov luam ntawv digital tau tshem tawm ntawm lub phaj- ua kev txwv tsis pub luam tawm ib txwm muaj, nws muaj cov kev xav tau ua kom zoo dua qub rau qhov ua ntej - ua cov thawj. Lub ntsiab kom zoo dua ntawm cov qauv luam ntawv digital yog nyob rau hauv nws cov txiaj ntsig zoo thiab muaj tseeb ntawm kev ua tiav thawj zaug, uas tuaj yeem ua kom rov zoo dua thiab ua kom zoo dua qub ntawm cov ntaub ntawv tsim. Thaum lub sij hawm npaj cov ntawv sau, tshwj xeeb yuav tsum tau them rau cov ntsiab lus tseem ceeb hauv qab no.
01
Manuscript quality benchmark
Nws raug nquahu kom muab qhov tseem ceeb rau qhov siab -cov khoom qub yog lub hauv paus rau kev luam ntawv digital, thiab lawv qhov kev daws teeb meem yuav tsum ncav cuag tus qauv ntawm 300dpi lossis siab dua. Thaum qhov zoo ntawm cov ntaub ntawv tseem ceeb tsis zoo, nws yog ib qho tsim nyog yuav tsum tau siv cov cuab yeej siv thev naus laus zis rau kev hloov pauv digital, nws raug nquahu kom siv lub tshuab luam ntawv nrog kev daws teeb meem ntawm 600dpi lossis ntau dua, nrog rau qhov kev daws teeb meem tiag tiag ntawm 300dpi, kom tau txais cov txiaj ntsig zoo tshaj plaws luam ntawv.
02
Xim luam tawm yam ntxwv
Thaum cuam tshuam nrog cov xim tshwj xeeb hauv kev luam ntawv digital, nws raug nquahu kom khaws tsawg kawg 3% ntawm qhov chaw nyob hauv thaj chaw kaj (qhov tseem ceeb) kom tsis txhob muaj kev cuam tshuam; Qhov tsaus ntuj (qhov ntxoov ntxoo ib feem) yuav tsum xyuas kom meej tias qhov siab tshaj plaws dot tsis tshaj 95% kom tsis txhob muaj cov number case ntau ntxiv; Rau cov teebmeem gradient, qhov kev hloov pauv hloov pauv tsis pub tsawg dua 10% yuav tsum tau teeb tsa.
03
Kev kho mob tshwj xeeb
Rau cov ntawv tseem ceeb, cov kab me me (pom zoo kom tsis pub tsawg dua 0.15mm), thiab cov duab me me, yuav tsum tau ua kom zoo dua. Thaum tus qauv tsim suav nrog cov xim xim, nws yuav tsum tau simulated los ntawm kev nthuav dav xim gamut peev xwm ntawm digital presses. Cov ntawv sau tsim xim sau qhov chaw yuav tsum tau sau cov xim ntawm CMYK hom, thiab tsis txhob siv xim tshwj xeeb lossis RGB xim, txwv tsis pub nws yuav ua rau muaj xim sib txawv.
Xaiv cov ntaub ntawv luam tawm
Cov luam ntawv digital muaj cov kev xav tau siab rau kev hloov pauv ntawm cov ntaub ntawv luam tawm, thiab nws yog qhov tsim nyog los xaiv cov ntawv zoo raws li cov khoom siv, cov ntsiab lus luam tawm thiab xa tawm -kev xav tau, thiab xyuam xim rau ib puag ncig kub thiab av noo tswj kom ntseeg tau tias luam ntawv zoo thiab cov khoom tiav.
01
Cov ntawv thov kev ua haujlwm
Xaiv daim ntawv nrog lub ntsej muag du los pab tus number case ua tib zoo sib xws, txo cov xim ntawm cov xim thiab cov streaks, thiab txhim kho qhov zoo ntawm cov luam ntawv digital. Cov ntawv luam tawm digitally yuav tsum muaj peev xwm nqus tau sai sai, tswj cov diffusion ntawm number case droplets, thiab xyuas kom meej cov xim ci thiab tsis tu ncua gradation. Kev hloov pauv ntawm cov dej noo ntawm daim ntawv yuav cuam tshuam rau kev luam ntawv, yog li nws raug nquahu kom khaws thiab siv nws hauv 30% txheeb ze av noo ib puag ncig.
02
Xim thiab cov khoom cuam tshuam
Cov xim dawb thiab cov yam ntxwv saum npoo ntawm daim ntawv yuav cuam tshuam rau cov xim ua haujlwm, yog li nws raug pom zoo kom xaiv cov ntawv nrog cov xim dawb thiab sib txuam xim gamut. Cov ntawv tuab lossis cov ntaub ntawv tshwj xeeb yuav tsum tau them sai sai rau qhov chaw ntawm cov duab kos thiab cov kab nrib pleb kom tsis txhob dhau ntawm cov ntawv tshaj tawm.
03
Tshaj tawm - kev hloov kho kom haum
Yog tias ib qho -sided lamination yog ib qho yooj yim ua rau curling thaum lub sij hawm lamination, ob -sided lamination yog pom zoo; Ua ntej khi, kev taw qhia ntawm daim ntawv strands yuav tsum tau txiav txim siab kom tsis txhob tawg ntawm qhov quav; Cov polish yog yooj yim tawg ntawm crease, thiab tus tsim yuav tsum tsis txhob complex creases los yog siv high gloss kho.
Ceev faj kom tshem tawm stains (blemishes)
Hauv kev coj ua ntawm cov qauv luam ntawv digital, vim yog lub hauv paus ntsiab lus ntawm kev luam tawm digital luam tawm raws li cov tshuab luam ntawv droplet deposition (inkjet) lossis electrostatic imaging technology (laser), nws cov xim luam tawm yog qhov sib txawv ntawm cov kev cai luam tawm, thiab cov qauv plaub- xim digital luam ntawv (CMYK) tsis tuaj yeem ncaj qha nthuav tawm cov xim ntawm cov xim uas tau pom los ntawm feem pua dots (tsuas yog 6 -xim version). Yog li ntawd, cov neeg tsim qauv yuav tsum siv PANTONE Spot-rau-CMYK hloov dua siab tshiab cov cuab yeej los nrhiav kev sib tw theoretical rau cov xim xim los ntawm kev sib piv cov xim daim npav database.
Saib xyuas daim teb thiab overprint
Ntawm cov khoom siv raws li kev tsim cov suab nrov, thaj chaw loj ntawm kev luam ntawv yog qhov teeb meem loj tshaj plaws. Tej zaum lawv yuav yog vim muaj kev hloov pauv ntawm tus nqi ntawm daim ntawv thiab tus nqi nws tus kheej. Rau qee qhov, cov nqi hluav taws xob electrostatic ntawm qhov chaw ntawm daim ntawv kuj hloov, ua rau cov streaks thiab cov xim tsis sib xws ntawm cov khoom thaiv, uas tsis yog qhov kev hloov kho tshiab. Los ntawm kev siv Photoshop lossis lwm yam software los tsim cov suab nrov hauv thaj teb, cov xovxwm tshiab tsis tshua muaj qhov teeb meem no piv rau cov xovxwm qub.
Ntawm qhov tsis sib xws, yog tias koj xav kom tau txais thaj tsam loj ntawm thaj chaw dub, siv cov xim dub tuab uas muaj xim daj, tus pin, xiav thiab xiav tus cwj mem hauv qhov sib txawv. Nws raug nquahu kom ua haujlwm nrog cov khoom siv los nrhiav thiab nrhiav tus lej tus lej zoo tshaj plaws. Sim muab qhab nia ntawm 60C, 40M, 40Y, 100K lossis 40C, 20M, 20Y, 100K thiab siv tag nrho plaub xim.
Cov luam ntawv digital tuaj yeem ua haujlwm ntawm 400 ~ 600dot / hauv, ua cov tonal dots los ntawm kev tsim ib daim phiaj. Vim tias pib nrog cov dots tsawg dua hauv thawj, daim phiaj tsuas yog qhov loj me los ntawm cov kab uas xaiv ntxoov ntxoo thiab tus nqi ntawm cov dots muaj. Yog tias tsuas muaj qhov tsawg ntawm cov duab ntxoov ntxoo tuaj yeem tau txais, kev hloov pauv hloov mus thoob plaws gradations thiab blends yog qhov nyuaj.
Saib cov zaub
Cov duab tso rau hauv cov zaub muaj cov xim gamut dav dua li cov luam ntawv digital, thiab cov khoom pov thawj, xws li inkjet proofing, muaj kev daws teeb meem siab txog 1200dpi. Nws yog qhov zoo tshaj plaws los ua pov thawj ntawm lub tshuab, tom qab ntawd rov ua cov khoom tsim tawm, thiab ua cov xim blocks rau kev siv hauv cov ntawv luam ntawv raws li ib txoj hauv kev los kho cov xim. Tau kawg, kev tswj hwm xim siab heev kuj yog ib qho kev daws teeb meem zoo, thiab tam sim no muaj qee tus neeg muag khoom uas tuaj yeem muab cov kev tswj hwm xim zoo tshaj plaws.
Xaiv cov software tsim nyog
Yog tias tib xim tsim cov duab hauv Illustrater, FreeHand, thiab Photoshop, thiab tom qab ntawd xa lawv mus rau Pagemaker lossis Quark Xpress, Yog tias koj hloov tag nrho cov ntaub ntawv mus rau CMYK xim qhov chaw, cov xim ntawm peb software yuav tsis sib xws, thiab koj yuav tsum tau kho cov xim rau cov xim sib npaug.
Sau cov khoom
Txhawm rau kom ntseeg tau tias tag nrho cov fonts, cov ntaub ntawv txuas nrog cov duab kos tau suav nrog hauv cov khoom (tsis txhob kos duab los ntawm kev txiav thiab pasting), txuag cov ntaub ntawv hauv cov qauv tsim nyog, thiab feem ntau pom zoo kom siv PDF / X-4 lossis TIFF hom ntawv ua cov ntawv tso tawm zaum kawg rau kev luam ntawv thiab muab rau cov neeg muab kev pabcuam rau kev luam ntawv kom txo cov xim sib txawv.
Tshaj tawm - ua tiav tam sim ntawd
Cov tshuab luam ntawv digital cov khoom lag luam yuav muaj qee qhov teeb meem thaum lub sij hawm khi, xws li ntawv curling, ntawv grain roughness, thiab lwm yam. Glazing agents txawv ntawm inks nyob rau hauv uas lawv tshwm nyob rau saum npoo ntawm daim ntawv thiab tsis tuaj yeem nqus tau. Thaum folding, cov kua roj vanish yooj yim tawg ntawm lub crease, yog li nws yog ib qho tsim nyog kom tsis txhob luam tawm ntawm lub crease, los yog siv cov suab nrov gloss los yog txo cov ntawv granularity nyob rau hauv lub crease cheeb tsam kom txo tau cov℃ntawm cracking, yog hais tias lub luam ntawv yog ib phau ntawv, thaum luam ib daim ntawv, qhov chaw sau npe yog ib qho teeb meem, cov duab ib feem yuav tsum tsis txhob ntau tshaj tus ncej them code, tshwj xeeb tshaj yog yuav tsum tau ceev faj txog kev sau npe. positioning, thiab cia mus txog 1/8 nyob rau hauv qhov ntau ntawm kev hloov.
Yog tias nws yog daim ntawv tuab, xyuas kom meej tias cov duab thiab cov creases nyob rau hauv daim ntawv tshaj tawm, tsis dhau ntawm cov ntawv tshaj tawm, kom txo cov ntawv tawg thiab polishing, thiab kev ua haujlwm zoo dua tuaj yeem tswj cov kev ua tsis tiav no. Yog tias koj cov khoom xav tau yog qhov muag heev, nco ntsoov ua tib zoo xaiv cov xovxwm digital thiab ua tib zoo tshuaj xyuas cov qauv khoom luam tawm los ntawm cov xovxwm digital.
