Los ntawm yav dhau los kev ceev xim sib cais, rau lub tshuab hluav taws xob sib cais tshuab, thiab tom qab ntawd ces mus rau lub teeb taws tso zis tshuab ntawm lub 1990s, cov cuab yeej ntawm cov ntsiab lus ntawm cov ntsiab lus tau raug siv lawm. Txawm hais tias cov cuab yeej ntawm cov khoom siv rau qhov sib txig sib luag tau tsim nyob rau lub sij hawm, nws tau nyiam cov xim ntawm txoj kev lag luam. Qhov teeb meem nyob rau hauv lub lag luam ntawm luam ntawv tsis tau txais kev saws. Hnub no, nkag mus rau hauv CTP cov caij nyoog, lub lag luam nyhav siab, txhais tau zoo tshaj plaws ntawm cov ntawv luam tawm, ib lub lag luam tshiab brand dot technology tuaj.
AM Kev Ntsuam Xyuas
Tam sim no, cov kab ke siv hauv cov xim phaj ua yog hu ua AM Screening. Lub ntsiab lus tseem ceeb hu ua Amplitude Modulation Screening (Daim Duab 1). Qhov no muaj xws li square mesh, saw hlau, vas vas thiab hais txog. Nyob rau hauv rooj plaub uas txoj hauj lwm thiab kev kho lub kaum sab xis ntawm cov dots yog tsau, qhov loj ntawm cov dots yog siv los qhia qhov tob ntawm daim duab.
Nws yuav tsum tswj kom muaj qhov ceev thiab mesh kaum ntawm lub network cable. Lub kaum sab xis ntawm ob qho xim xim yuav tsum yog 30 degree los yog ntau tshaj kom tsis txhob muaj kev sib tsoo ntawm qhov net. Feem ntau qhov C version muab tso rau ntawm 15 degree, M version: 45 degrees, K version. : 75 degree (M version los yog BK version tau hloov), thiab Y version muab tso rau hauv 90 degree. Hauv qhov no, lub Y version yuav raug sib cais los ntawm lwm cov xim phiaj xwm los ntawm tsuas yog 15 degrees. Txij li nws yog sib dua dua lwm yam peb xim, txawm tias muaj kev sib tsoo, Tsis pom.
Ntawm qhov one hand, AM Screening tuaj yeem ua kom tiav printing luam ntawv, thiab tib lub sij hawm nws yooj yim los tsim Rosette, cuam ntawm Moires, Tone dhia, ntawv nyeem thiab hloov maj mam reproducibility. . Tsis tas li ntawd, kev siab tshaj qhov tseeb yog qhov yuav tsum tau luam tawm.
FM Kev Ntsuam Xyuas
Ob peb xyoos dhau los, ntau Image setter manufacturers tsim ib zaus hu ua FM (FM Screening), cov ntawv nyeem tag nrho yog Kev Tawm Tseg Zaus (Frequency Modulation Screening) (Xamua 2). Cov diameters ntawm cov kev sib raug zoo no yog ntawm 8-30 microns, thiab qhov zoo ntawm txhua qhov chaw zoo yog tib yam. Qhov qhia ntawm qhov tob xim qhov sib txawv ntawm qhov ntawm qhov kev ua haujlwm ntawm qhov dav hlau. Lub ntom ntawm cov duab yog qhia los ntawm qhov ceev. Lub ntom ntawm cov dots loj, thiab xim yog ib tsos tsaus tsawv. Cov txheej txheem yog los ua qhov kev nplua no random faib.
FM Screening muaj qhov zoo:
1. Yuav tsis muaj kev sib tsoo nets lossis net paj.
2. Qhov tshwm sim me me ua rau tuaj yeem tshwm sim ntxiv.
3. Tshem tawm lub Tone Jump ntawm midtones.
4. Qhov teeb meem sau npe tsis cuam tshuam rau qhov tshuav nyiaj li cas.
Cov kev tsis zoo ntawm FM Kev Ntsuam Xyuas:
1. Lub teeb theem thiab kev sib haum xeeb yog qhov ntxim nyiam thiab ntxim nyiam.
2. Qhov nruab nrab-qhov teeb meem ntawm qhov nruab nrab yog qhov siab heev, thiab qhov teebmeem loj tshaj yog tswj tsis tau.
3. Yuav tsum tau muaj qhov tseeb thiab xav tau cov ntawv sau cia.
4. Kev ruaj ntseg ntawm cov zis tawm zaj duab xis, kev tsim kho thiab kev pom tseeb ntawm kev nplua zoo.
5. Thaum luam ntawv, txoj hauj lwm uas yooj yim yuav poob, thiab txoj haujlwm sib sib zog nqus yooj yim.
Hybrid AM / FM Screening
Nyob rau ntawm 1-10% lub teeb thiab 90-99% qhov tob, nws yuav siv tib qhov loj me me mesh cov ntsiab lus raws li FM Kev Ntsuam Xyuas (Daim Duab 3), thiab nthuav qhia cov duab los ntawm qhov sib txawv ntawm cov dots. Cov theem hloov hauv nruab nrab, nyob nruab nrab ntawm 10-90%, yuav pauv qhov loj ntawm cov teev xws li AM Screening. Txawm li cas los xij, qhov chaw ntawm txhua qhov chaw sib tw yog random, thiaj li tsis tas xav txog qhov teeb meem "network angle".
Lub teeb lub teeb thiab sib sib zog nqus
Txoj hauj lwm ntawm lub teeb thiab qhov sib sib zog nqus yog muab faib, thiab qhov sib txawv ntawm qhov sib txawv me ntsis yuav txawv, yog li qhia qhov kev hloov ntawm theem hauv daim duab. Nws yog tsim nyog sau cia tias qhov chaw ntawm lub teev yog tshwj xeeb uas muab xam los xyuas kom tsis txhob sib tshooj sib, thiab yuav tsis muaj qhov sib txawv ntawm qhov sib txawv. Qhov no txwv tsis pub ua kom tawv nqaij.
Thaum daws teeb meem ntawm 2400dpi, qhov tsawg kawg nkaus dot inch yog li 10.5 microns (piv txwv li 1/2400 nti). Txawm hais tias cov dots no zoo tuaj yeem tshwm rau ntawm cov ntawv xov xwm, qhov tsis ruaj tsis khov hauv kev luam ntawv feem ntau ua rau poob ntawm daim duab. . Txawm li cas los xij, txoj kev sib tw ntawm hom tshiab no yog muab sib dhos ua ke ntawm ntau qhov me me rau hauv ib qho loj tshaj, thiab ob lossis peb yam tsawg kawg nkaus (txhua qhov muaj lub kaum ntawm 10.5 micrometers) ua ke los ua ib qho loj teev uas muaj txoj kab uas txawv ntawm 21 los sis 32 micrometers. . Xws li qhov loj ntawm qhov point yog tsim rau kev luam ntawv, thiab tuaj yeem txhim kho qhov reproducibility thiab stability ntawm luam ntawv.
Ib qho loj ntawm ob lossis peb yam pips (txhua qhov muaj lub cheeb ntawm 10.5 microns) yog 21 lossis 32 microns inch. Xws li qhov loj ntawm qhov point yog tsim rau kev luam ntawv, thiab tuaj yeem txhim kho qhov reproducibility thiab stability ntawm luam ntawv.
Midtone ib feem
Hauv qhov nruab nrab kev hloov, qhov chaw ntawm qhov teev yuav tsum tau xaiv xws li FM Kev Ntsuam Xyuas, tab sis qhov tob ntawm txheej yog qhia los ntawm txoj kev ntsuam xyuas AM, uas yog, los ntawm kev hloov ntawm qhov loj ntawm cov teev, qhov zoo ntawm cov dots yog heev txuam vim kev tshaj tawm. Yog li ntawd, kev hloov ua kom yooj yim yuav zoo dua. Tsis tas li ntawd, ib txoj kev tshwj xeeb raug coj los mus tiv thaiv kev sib tshooj ntawm cov dots, uas tig mus daws cov teeb meem ntawm cov tawv dawb.
Ntaus ntawm AM / FM hybrid network:
Qhov kev ua haujlwm ntawm qhov kev lag luam no tsuas yog ua tau kom zoo dua qub xwb, tiam sis tsis cuam tshuam txog qhov ua tau zoo npaum li cas. Nws tsuas xav tau ua raws li cov kev cai 2400dpi / 175lpi cov txheej txheem thiab cov khoom siv los ua kom tiav cov ntawv luam ntawm 300lpi high-line dots. Hauv yav dhau los, thaum siv cov ntawv teev kab ua haujlwm hauv high school, txhua txoj haujlwm yuav tsum tau tswj xyuas nruj.
Txhim kho cov ntawv zoo
1. Cov kab hauv daim qhia kev, cov plaub hau ntawm cov ua cim thiab cov muag me ntsis yog dlaim phaj, tsis muaj cov npoo tawv thiab tawg nthe.
2. Ua kom tsis txhob muaj teeb meem ntawm daim ntaub sib tsoo, npo, suab thiab ntoo grain rau ntawm khaub ncaws thiab tus qauv thiab qhov netting yog interlaced.
3. Tshem tawm qhov pom ntawm cov dub dub lossis cov teeb pom kev zoo.
4. Cov nyhuv gradient ntau dua qhov qub, thiab lub vijtsam tiaj tiaj thiab lub teeb theem zuj zus.
5. Txhim kho qhov xim ntawm cov khaub ncaws, txiv hmab txiv ntoo, paj thiab lwm yam khoom.
Lub koom haum AM / FM hybrid network "Vision" yog ib qho kev sib txuas ntawm tag nrho cov kev zoo ntawm kev ntsuam xyuas AM thiab Kev Ntsuam Xyuas FM. Nws yog complemented los ntawm ib tug high degree ntawm sab nraud CTP thiab ultra-hardkey thermal phaj. Siv CtP luam tawm tshuab kom zoo dua.
