Thaum txoj kev ua haujlwm, kev sib txuas ntawm cov ntawv, kua number case thiab cov ciav hlau muaj cov qhob, ua tau zoo li lub tshuab khoom thiab cov ntawv luam tawm. Cov kev hloov no tsuas yog cuam tshuam rau txoj kev ua haujlwm xwb, tabsis qhov tseem ceeb tshaj. Yog li ntawd, qhov kev ntsuam xyuas yuav tsum muaj kev pom zoo rau kev txiav txim siab rau txoj kev luam ntawv mus qee zaus. Daim ntawv no tshuaj xyuas cov xwm txheej uas ua rau cov txheej txheem luam ntawv yuav ntiav.
Ua ntej. Stacking ntawm daim ntawv thiab number case residue ntawm daim pam
Muaj ntau ntau yam ua rau vim li cas qhov kev luam tawm thaum lub sijhawm ua haujlwm, tab sis qhov tseem ceeb tshaj plaws yog lub hnab ntawv thiab tus cwj mem ntawm daim pam. Feem ntau hais lus, daim pam ntxhuav yuav rov qab tom qab txog 1500 nplooj ntawv luam tawm, thiab cov nyhuv stacking yog feem ntau cuam tshuam los ntawm cov nram qab no.
1. Cov nyhuv ntawm cov ink viscosity ntawm lub txuam nrog
Tus cwj mem ntawm tus cwj pwm viscosity yog qhuav thiab khov, thiab cov viscosity qhuav yog to taub ntawm tus cwj mem xaj uas tsis muaj dampening kua. Lub viscosity ntub yuav to taub raws li tus number case thaum lub sij hawm luam ntawv. Viscosity tshaaj ntawm dampening kua. Lub siab ntsws yog hloov thaum lub sij hawm batch luam ntawv. Thaum cov xim ntawm tus cwj pwm xau khov qis dua qhov tsis pub tshaj ntawm daim ntawv, cov duab tsis txua lossis tsis muaj dab nyob rau hauv tag nrho cov luam ntawv, thiab nws tsis yooj yim los ua cov ntawv khaws cia; Thaum twg tus number case yog nplaum Thaum lub suab sib cav ntau dua li ntawm daim ntawv tsis pub tshaj, cov ntawv luam yuav ua ntau dua thiab ntau dua thaum lub sij hawm luam ntawv. Vim yog lub xauv npab siab ntawm tus cwj pwm, ntau cov ntaub plaub mos mos raug rub tawm ntawm daim ntawv, ua rau daim ntawv tuaj yeem tawm ntawm daim pam. Tsis tas li ntawd, qhov saum npoo ntawm daim ntawv muaj ib qho me me ntawm cov hmoov me me (ntawv hmoov), thiab cov khoom me me kuj yooj yim sib cais los ntawm daim ntawv thiab adhered rau daim duab dub uas yog daim pam rau ib pawg.
Thaum pib ntawm luam ntawv, uas yog, tom qab lub pam raug ntxuav, tus nqi ntawm tus cwj mem hauv daim duab nraub qaum (mesh, line, thiab field) tau xa mus rau ntawm daim ntawv 100% raws li qhov qub npaum li cov dampening kua. Thaum luam ntawv mus rau 1500 los yog thaum lub lubricating kua tsis zoo, tus cwj mem ntawm daim pam yuav nce, uas yog ntau pom tseeb los ntawm high-power micrographs. Cov dots uas tau pauv mus rau hauv daim ntawv yog puas hauv lub cheeb, thiab tsis muaj qhov dawb dots nyob nruab nrab ntawm cov dots. Vim li no, cov dots tshwm teeb, uas qhia tau hais tias tus nqi ntawm number case muab xa mus rau ntawv yog txo. Yog tias koj tsis ntxuav daim pam los sis kho tus nqi ntawm cov kua txhuam hniav thiab tus nqi ntawm tus cwj mem kom zoo, daim ntawv, cov hmoov ntawv thiab cov khoom seem uas muaj nyob hauv daim pam yuav ntau dua, cov kab ntawv tseem yuav txuas ntxiv thiab luam tawm ntawm daim ntawv. Ib feem uas tsis muaj cwj mem nyob hauv nruab nrab ntawm cov teev yuav tsum ntxiv nthuav, thiab sib ntawm lightening lub mesh yog ntau pom tseeb.
2. Cov nyhuv ntawm qhov nyiaj ntawm dampening daws on phenomenon txuam nrog
(1) Cov nyhuv ntawm cov tshuaj dampening kua rau ntawm tus viscosity ntawm tus number case
Raws li pom tau los ntawm cov saum toj no, tus number case viscosity muab faib ua ob hom: qhuav viscosity thiab ntub viscosity. Ntub dej viscosity yog qis tshaj qhuav dej qhuav vim tias noo noo thiaj li xau ntawm tus cwj mem. Nws tuaj yeem pom tau tias qhov nyiaj dampening kua muaj ib feem xyuam rau kev xev npum ntawm tus cwj pwm, uas yog, nws muaj kev cuam tshuam rau ntawm qhov tshwm sim txuam nrog. Feem ntau, cov kua xauv npog yuav txo nrog cov kua dej dampening, tab sis nws muaj kev cuam tshuam los ntawm ntau yam xws li hom ntawm tus cwj mem, qauv thiab ntsuas ntawm tus cwj mem kua ink, thiab lwm yam kev sim uas qhia tau tias number case yog ntub viscous. Raws li qhov nyiaj dampening kua nce, nws tsis yog ib txwm txo. Yog li ntawd peb yuav tsum xyuam xim rau kev soj ntsuam thiab kev hloov kho.
(2) Qhov dampening tov Ntxiv rau qhov cawv ntawm cov hmoov ntawv thiab tus cwj mem tso rau ntawm daim pam, daim ntawv hmoov thiab ntawv txheej kuj tuaj yeem ua tau thiab muab pov tseg los ntawm txoj kev dampening, uas yog txau rau ntawm daim pam. Qhov tshwm sim tshwm sim no tshwm sim rau ntawm daim ntawv uas yog stackable heev thiab txaws ntawm qhov tsis-daim duab ntawm ntu ntawm daim pam. Thaum twg tus nqi ntawm cov khoom txig nce mus txog qee theem, nws yuav nthuav dav mus rau qhov kev cuam tshuam. Hauv qhov xwm txheej ntawm lub plhaub tiab ntawm txheej, cov viscosity ntawm tus cwj mem, qhov kub, qhov av, thiab qhov ceev ntawm qhov khoom, qhov tso nyiaj tsis tuaj yeem tsis ntev li thaum lub tshuaj dampening muab rau tus taw. Tau kawg, cov tshuaj kua dampening hais ntawm no yog muab rau qee qhov twg, txawm tias nws tau luam tawm nrog qee qhov dampening solution, nws yuav tsis ua dej npe ntawm cov khoom luam tawm, thiab qhov zoo ntawm cov khoom luam yuav tsum tau lav.
(3) Ib co offset cov neeg ua haujlwm luam tawm "ink number and water balance", thiab pheej yig txo cov dej hauv txoj kev luam ntawv, tabsis tsis txhob cuam tshuam txog qhov teebmeem ntawm cov saum toj no hais txog cov teebmeem ntawm lub plab. Raws li qhov tshwm sim, qhov tshwm sim txuam nrog yog mob hnyav thiab lub blotting tseem poob qis.
