Yuav ua li cas kom ruaj ntseg ntawm cov khoom luam tawm digital thiab txhawb cov neeg siv khoom txaus siab ntxiv!

Rau cov tuam txhab luam ntawv, cov cuab yeej siv tau zoo yog qhov tseem ceeb, tab sis ruaj khov luam ntawv zoo yog qhov tseem ceeb heev. Piv txwv li, cov duab luam tawm yog ib qho tseem ceeb tshaj plaws ntawm kev siv digital luam ntawv. Txhua xyoo, cov ntawv kawm tiav, daim ntawv qhia hnub tus kheej, cov phau ntawv duab, thiab cov khoom zoo sib xws yog nrov hauv khw. Txawm li cas los xij, yog tias cov ntawv luam tawm raug kev txom nyem los ntawm cov teeb meem xws li tsis txaus xim saturation, xim sib txawv, los yog tsis pom tseeb, cov nyhuv luam ntawv yuav tsis zoo thiab yuav tsis nyiam cov neeg siv khoom lossis tsim kev lag luam. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau txais txoj hauv kev zoo los tshuaj xyuas thiab tswj xyuas cov ntawv luam tawm kom zoo thaum lub sijhawm luam ntawv digital.Document Quality Control01Color ModeWhen tau txais cov neeg siv khoom cov ntaub ntawv, thawj kauj ruam yog xyuas lawv cov xim hom, uas yog qhov tseem ceeb tshwj xeeb hauv kev luam ntawv xim. Hauv kev luam ntawv digital, cov xim xim luam ntawv feem ntau yog siv raws li nws tuaj yeem ua tau raws li cov neeg siv khoom xav tau. Ua ntej ua qhov chaw xim luam ntawv, cov xim xim yuav tsum tau teeb tsa kom zoo, uas suav nrog kev txiav txim siab seb puas luam tawm ncaj qha nrog cov xim pleev xim lossis hloov cov xim xim rau hauv CMYK rau kev luam ntawv.02File FormatCov ntaub ntawv nyiam tshaj plaws rau kev luam ntawv digital feem ntau siv cov ntawv luam tawm xws li PDF lossis PS. Nplooj ntawv qhov loj me yog qhov loj ntawm cov ntawv luam tawm. Tsis tas li ntawd, nws yog ib qho tseem ceeb kom ntseeg tau tias qhov loj - cov ntaub ntawv loj yog qhov tseeb; txwv tsis pub, rework lossis reprinting tej zaum yuav tsum tau thaum lub sij hawm tom qab ua.03Cov ntsiab lus Tsis pub dhau lub Trim AreaCov ntsiab lus hauv cheeb tsam trim muaj xws li cov ntawv nyeem, duab, thiab cov duab. Hais txog cov ntawv nyeem, qhov teeb meem feem ntau yog kev sib txuam font. Yog tias cov fonts siv hauv cov neeg siv cov ntaub ntawv tsis muaj, nws yuav tsum tau sib tham nrog tus neeg siv khoom hloov font, kom tus neeg siv khoom muab cov ntaub ntawv font cuam tshuam, lossis hais kom tus neeg siv khoom kos cov fonts thaum tsim cov ntawv PDF. Rau cov duab, vim lawv yog cov ntaub ntawv vector, feem ntau yuav tsum tau them nyiaj rau hom xim thiab hom ntawv.

04Image ContentHais txog cov duab, nws yog thawj qhov tsim nyog los tswj cov duab daws teeb meem. Feem ntau, cov duab xim yuav tsum muaj qhov kev daws teeb meem tsawg kawg yog 300 dpi, cov duab grayscale feem ntau xav tau 600 dpi, thiab xim dub - thiab - cov duab kab dawb xav tau 1200 dpi. Thib ob, hom xim ntawm cov duab xim yuav tsum yog CMYK, thiab nws yog qhov zoo tshaj plaws los xyuas kom meej cov zis hauv TIFF lossless compression hom. Qhov no txhawb kev luam ntawv thiab ua kom muaj txiaj ntsig zoo rau kev tsim cov duab zoo tshaj plaws.Raw Material Control01PaperThe range of substrates for digital printing is wide, but paper tseem yog thawj substrate. Nrog rau kev txhim kho thev naus laus zis, kev luam ntawv digital imposes cov kev xav tau siab dua ntawm lub cev, tshuab, thiab kho qhov muag ntawm daim ntawv. Piv txwv li, hauv kev luam ntawv digital, daim ntawv tuab yuav tsum tsis sib xws kom tsis txhob cuam tshuam qhov sib npaug ntawm tus number case; daim ntawv saum npoo yuav tsum du li sai tau nrog ob peb pinholes; nws yuav tsum muaj qee lub zog tensile thiab tsim kua muag tiv thaiv kom tsis txhob muaj plua plav lossis fiber ntau hauv cov khoom siv high -ceev digital printing; rau cov ntawv xov xwm thiab cov phau ntawv, qhov opacity siab dua ntawm daim ntawv yog qhov nyiam, qhov twg rau cov ntawv sau, cov ntawv xa nyiaj, thiab lwm yam ntaub ntawv luam tawm, nws yog qhov txaus yog tias tsis muaj kev qhia- dhau ntawm.02InkInk kuj tseem ua lub luag haujlwm tseem ceeb hauv kev luam ntawv digital. Cov luam ntawv digital yuav tsum muaj siab gloss ntawm number case; Cov kua nplaum zaj duab xis yuav tsum nyob ruaj khov thaum raug dej, roj, cov kuab tshuaj, thiab lwm yam khoom kom tsis txhob muaj xim lossis fading. Qee cov ntawv luam tawm digital tuaj yeem raug tshav ntuj rau lub sijhawm ntev, yog li tus number case yuav tsum muaj qhov pom kev zoo. Kev ruaj ntseg kuj tseem yuav tsum muaj nyob rau hauv cov ntsiab lus ntawm pH, conductivity, viscosity, nkag mus, nto nro, ntom, thiab xim sib txawv kom tau raws li cov tshuab luam ntawv, thiab tus number case yuav tsum tsis yog - lom thiab environmentally friendly.Tom qab xyuas cov ntsiab lus saum toj no, ib kauj ruam ntxiv yuav tsum tsis txhob hnov ​​qab. Ua ntej kev tsim khoom, kev ntsuas cov xim zoo nkauj yuav tsum ua ntej, ua raws li cov qauv luam ntawv, thiab cov ntsiab lus ntawm cov qauv ntsuas yuav tsum tau ua tib zoo xyuas thiab kaw. Zoo ib yam li cov cuab yeej luam ntawv ib txwm muaj, cov cuab yeej luam ntawv digital kuj tuaj yeem ntsuas los ntawm kev tswj cov ntawv sau npe raug, qhov ceev, chroma, grey tshuav nyiaj li cas, thiab dot nce. Cov khoom siv calibration kuj suav nrog cov xim calibration, number case ntom calibration, ink conductivity calibration, thiab tsis siv neeg siab calibration.Piv rau cov khoom siv luam ntawv, cov tshuab luam ntawv digital muaj kev nruj dua ib puag ncig, thiab lawv cov ntawv luam tawm tau yooj yim cuam tshuam los ntawm ib puag ncig. Qhov no yog vim qhov hloov pauv ntawm qhov kub thiab av noo cuam tshuam rau kev hloov pauv tus lej thiab tuaj yeem ua rau daim ntawv deformation, cuam tshuam rau daim ntawv pub thiab kev sau npe thaum luam ntawv. Tsis tas li ntawd, cov plua plav ib puag ncig tuaj yeem cuam tshuam rau tus number case thiab ntawv cov khoom, yog li cuam tshuam cov xim sib xws hauv cov luam ntawv digital. Yog li ntawd, txhawm rau tswj kev luam ntawv zoo ntawm cov ntawv luam tawm zoo dua, lub rooj cob qhia tshwj xeeb yuav tsum tau teeb tsa rau cov tshuab luam ntawv digital, nruab nrog cov cua txias tshwj xeeb, dehumidification thiab humidification systems, thiab qhov cua. Lub rooj cob qhia kub yuav tsum tswj ntawm 23-27 degree, av noo ntawm 40% -60%, thiab qhov chaw tsim khoom yuav tsum tau ua kom huv si. Tsis tas li ntawd, kev ntsuas yuav tsum tau ua kom txo qis cov neeg ua haujlwm txav, kaw lub qhov rooj tam sim, thiab tswj qhov chaw ruaj khov, tsim lub hauv paus rau kev luam ntawv zoo ib yam.
