xov xwm

Paub meej: Hauv xyoo tas los no, pantong xim luam ntawv tau siv dav hauv kev luam ntawv ntawm cov khoom ntim khoom.Pantong xim yog hais txog cov xim uas tsis yog plaub xim thiab sib xyaw ntawm plaub xim, uas yog sau tshwj xeeb nrog ib tus cwj mem tshwj xeeb.Pantong colour printing txheej txheem feem ntau yog siv nyob rau hauv ntim printing los luam loj cheeb tsam tom qab xim.Daim ntawv no luv luv piav qhia txog pantong xim luam ntawv tswj kev txawj ntse, cov ntsiab lus rau cov phooj ywg siv:

Pantong xim luam ntawv

Pantong xim luam ntawv yog hais txog cov txheej txheem luam ntawv uas lwm cov xim tsis yog daj, magenta, cyan thiab dub number case yog siv los luam cov xim ntawm cov ntawv sau qub.

Cov khoom ntim los yog npog ntawm cov phau ntawv thiab cov ntawv xov xwm feem ntau yog tsim los ntawm cov xim sib txawv ntawm cov xim sib txawv lossis cov xim xim thiab cov lus tsis tu ncua.Cov xim blocks thiab cov lus no tuaj yeem luam tawm nrog plaub thawj xim tom qab muab faib ua xim, lossis pantong xim tuaj yeem muab faib, thiab tom qab ntawd tsuas yog ib qho xim xim pantong tuaj yeem luam tawm hauv tib xim thaiv.Hauv kev xav txog kev txhim kho kev luam ntawv zoo thiab txuag tus naj npawb ntawm overprints, pantong xim luam ntawv yuav tsum raug xaiv.

1, Pantong xim kuaj pom

Tam sim no, feem ntau ntawm kev ntim khoom hauv tsev thiab luam ntawv lag luam ntawm antong xim ntsuas thiab tswj txhais tau tias feem ntau vam khom cov kev paub ntawm cov neeg ua haujlwm los xa cov xim pantong xim.Qhov tsis zoo ntawm qhov no yog qhov piv ntawm pantong number case tsis raug txaus, lub sijhawm xa tawm ntev, cuam tshuam ntawm cov ntsiab lus tseem ceeb.Qee lub tuam txhab ntim khoom loj thiab luam ntawv muaj zog tau siv lub pantong xim number case txuam rau nws txoj kev tswj hwm.

Lub pantong xim number case txuam system yog tsim los ntawm lub computer, xim txuam software, spectrophotometer, analytical tshuav nyiaj li cas, tus cwj pwm tus cwj mem ntsuas thiab ink zaub ntsuas.Nrog rau qhov system no, cov ntawv thiab tus cwj mem tsis tau siv los ntawm lub tuam txhab feem ntau tau sau rau hauv cov ntaub ntawv, cov xim sib txuam software yog siv los ua kom haum cov xim xim uas muab los ntawm cov neeg siv khoom, thiab CIELAB tus nqi, tus nqi ceev thiab △E yog ntsuas los ntawm spectrophotometer, thiaj li hais tias cov ntaub ntawv tswj ntawm pantong xim txuam number case tuaj yeem pom tau.

2. Yam cuam tshuam rau pantong xim

Hauv cov txheej txheem luam ntawv, muaj ntau yam uas ua rau chromatic aberration hauv pantong xim number case ntau lawm.Cov yam tseem ceeb no tau tham hauv nqe lus hauv qab no.

Kev cuam tshuam ntawm daim ntawv ntawm xim:

Kev cuam tshuam ntawm daim ntawv ntawm tus number case txheej xim yog feem ntau xav txog peb yam

1) Daim ntawv dawb: Daim ntawv nrog cov xim sib txawv (lossis nrog qee cov xim) muaj qhov sib txawv ntawm cov xim ntawm cov xim luam ntawv txheej.Yog li ntawd, nyob rau hauv qhov tseeb ntau lawm yuav tsum sim xaiv tib lub whiteness ntawm daim ntawv printing, thiaj li yuav txo tau cov whiteness ntawm daim ntawv ntawm cov xim luam ntawv.

2) absorb muaj peev xwm: tib tus cwj mem luam tawm nyob rau hauv tib yam kev mob rau txawv absorbing peev xwm ntawm daim ntawv, yuav muaj sib txawv printing luster.Cov ntawv tsis-txheej thiab txheej ntawv piv, cov xim dub txheej yuav tshwm grey, npub, thiab xim number case txheej yuav tsim drift, los ntawm cyan number case thiab magenta ink blending tawm ntawm cov xim ua tau zoo tshaj plaws.

3) glossiness thiab smoothness: lub glossiness ntawm daim ntawv yog nyob ntawm glossiness thiab smoothness ntawm daim ntawv.Qhov saum npoo ntawm daim ntawv luam ntawv yog ib qho chaw gloss, tshwj xeeb tshaj yog cov ntawv coated.

Cov nyhuv ntawm kev kho deg ntawm xim:

Kev kho saum npoo ntawm cov khoom ntim yog tsuas yog them nrog zaj duab xis (lub teeb zaj duab xis, matt zaj duab xis), glazing (npog lub teeb roj, matt roj, UV kua roj vanish) thiab lwm yam.Cov ntawv luam tawm tom qab cov kev kho saum npoo no, yuav muaj qhov sib txawv ntawm cov xim hloov thiab xim hloov xim.Npog zaj duab xis ci, npog cov roj ci ci thiab UV roj, xim ceev nce;Thaum txheej matte zaj duab xis thiab npog cov roj matte, cov xim ceev yog txo.Kev hloov tshuaj lom neeg feem ntau yog los ntawm cov nplaum nplaum, UV lub hauv paus roj, UV roj muaj ntau yam organic solvents, uas yuav ua rau cov xim ntawm cov luam ntawv number case txheej hloov.

Qhov cuam tshuam ntawm qhov system sib txawv:

Ua los ntawm kev faib khoom, qhia cov xim number case yog "qhuav", txheej txheem ntawm kev koom tes, tsis muaj dej thiab luam ntawv yog "ntub luam ntawv" txheej txheem, cov kua ntub dej yog koom nrog hauv txheej txheem luam ntawv, yog li hauv offset luam ntawv number case yog ua tiav rau hauv Ib qho dej-hauv-roj emulsion, emulsion number case vim hloov pauv tom qab kev faib tawm ntawm cov xim pigment hauv txheej number case, yog khi los tsim tawm xim, cov khoom luam tawm kuj yog xim tsaus, tsis ci.

Tsis tas li ntawd, qhov sib txawv ntawm desalinator thiab qhuav desalinator ntom muaj qee yam cuam tshuam rau cov xim.Kev ruaj ntseg ntawm tus cwj mem siv los sib tov cov xim pantong, lub thickness ntawm tus number case txheej, qhov tseeb ntawm tus cwj mem hnyav, qhov sib txawv ntawm qhov qub thiab tshiab number case mov cheeb tsam ntawm lub tshuab luam ntawv, ceev ntawm cov ntawv luam ntawv, thiab cov tus nqi ntawm cov dej ntawm lub tshuab luam ntawv kuj tseem muaj qhov sib txawv ntawm cov xim sib txawv.

3, Pantong xim tswj

Txhawm rau ua kom tiav, txhawm rau kom ntseeg tau tias cov xim sib txawv ntawm tib lub batch thiab cov khoom sib txawv ntawm cov khoom ua tau raws li lub teb chaws cov qauv thiab cov neeg siv khoom, cov xim pantong yog tswj raws li hauv qab no hauv cov txheej txheem luam ntawv:

Ua pantong xim card

Ua ntej, raws li tus qauv xim qauv muab los ntawm cov neeg siv khoom, siv lub khoos phis tawj xim sib txuam kom muab qhov feem ntawm pantong xim number case;Tom qab ntawd tawm ntawm tus cwj mem coj mus kuaj, nrog cov twj ntsuas tus cwj mem tsis zoo, tus cwj mem tso ntsuas ntsuas "qhia" qhov sib txawv ntawm cov qauv xim;Tom qab ntawd raws li lub teb chaws tus qauv (los yog cov neeg siv khoom) ntawm cov xim sib txawv ntawm qhov yuav tsum tau muaj, nrog spectrophotometer los txiav txim tus qauv, ntiav txwv, sib sib zog nqus txwv, luam ntawv qauv xim daim npav (xim txawv tshaj tus qauv yuav tsum tau kho ntxiv).Ib nrab ntawm daim npav xim yog cov qauv xim zoo tib yam, ib nrab yog cov xim xim xim, qhov no yog los pab txhawb kev siv cov tshuaj ntsuam xyuas zoo.

Txheeb xyuas qhov xim

Xav tias daim ntawv yog qhov tseem ceeb uas cuam tshuam rau cov xim sib txawv, yog li ua ntej txhua lub luam ntawv siv cov ntawv luam ntawv tiag tiag "qhia" xim qauv, daim npav xim sib piv los ua micro-kho, txhawm rau tshem tawm cov ntawv ntawm cov ntawv.

Printing tswj

Lub tshuab luam ntawv siv cov ntawv luam ntawv xim xim los tswj cov tuab ntawm pantong xim number case txheej, thiab pab ntsuas tus nqi tseem ceeb thiab BK tus nqi ntawm cov xim nrog lub ntsuas densitometer kom kov yeej qhov sib txawv ntawm cov xim qhuav thiab ntub dej ntawm tus number case.

Hauv luv luv, hauv ntim luam ntawv, muaj ntau yam laj thawj rau pantong xim aberration.Nws yog ib qho tsim nyog los tshuaj xyuas cov laj thawj sib txawv hauv kev tsim khoom tiag tiag, daws cov teeb meem, sim tswj qhov sib txawv ntawm qhov tsawg kawg nkaus, thiab tsim cov khoom ntim khoom uas txaus siab rau cov neeg siv khoom.
