1. Ua kom nkag siab txog kev sib raug zoo ntawm kev luam ntawv siab thiab number case txheej thickness
Kev tsim nyog luam ntawv siab yog ib qho tseem ceeb rau kev ua tiav kev hloov pauv ntawm tus number case txheej ntawm lub phaj nto. Kev luam ntawv tsis txaus lossis tsis sib npaug ntawm lub phaj saum npoo yuav cuam tshuam rau kev hloov pauv ntawm tus number case txheej. Thaum lub siab ntawm qhov layout tsis txaus lossis tsis sib npaug thaum luam ntawv, cov xim number case ntawm cov khoom luam tawm yuav plam, thiab cov tuab ntawm cov xim xim ntawm tag nrho cov txheej txheem yuav tsis sib haum. Kev nce tus number case tuaj yeem ua rau muaj qhov tsis xws luag los ntawm kev sib cuag tsis zoo ntawm cov txheej txheem number case thiab cov substrate los ntawm kev luam ntawv tsis txaus, tab sis nws kuj yog ib qho yooj yim los ua smearing ntawm cov khoom luam tawm. Yog li ntawd, koj yuav tsum tau kho qhov luam ntawv siab ua ntej, thiab tom qab ntawd kho tus number case xa tuaj rau ntawm qhov layout, kom koj thiaj li tau txais txiaj ntsig zoo.
2. Kov qhov kev sib raug zoo ntawm kev luam ntawv ntawm daim ntawv thiab lub thickness ntawm tus number case txheej
Daim ntawv uas tsis zoo nto smoothness muaj ceev number case nqus thiab loj number case nqus. Thaum luam ntawv hom ntawv no, yog tias lub tshuab luam ntawv tsis txaus lossis tsis sib xws, nws yuav yooj yim rau pom tom qab luam ntawv. Yog hais tias tus number case ntim tau nce, cov number case txheej yuav thicker, thiab yog tias cov luam ntawv ceev qeeb, smearing yuav yooj yim tshwm sim. Rau cov ntawv uas tsis zoo deg smoothness, lub printing siab yuav tsum tau nce raws li; rau daim ntawv nrog zoo nto smoothness, xws li coated ntawv thiab iav cardboard, cov number case txheej yuav tsum nyias li sai tau kom tsis txhob smearing. Los ntawm qhov kev xav ntawm kev tiv thaiv adhesion, luam ntawv loj-thaj daim hlau yuav tsum tau txais" tsaus nti number case luam ntawv", uas yog, xim ntawm tus number case yuav tsum tau kho kom tsaus, thiab txheej number case yuav tsum. yuav thinner, thiaj li hais tias nws yuav tsis tau tsuas yog ua tau raws li qhov yuav tsum tau ntawm printing hue, tab sis kuj zam av.
3. Muab kev sib raug zoo ntawm cov yam ntxwv ntawm lub phaj thiab lub thickness ntawm cov luam ntawv number case txheej
Qhov zoo ntawm lub phaj, lub thickness ntawm cov luam ntawv number case txheej thiab lub tshuab luam ntawv siab muaj ib qho kev sib raug zoo. Yog hais tias lub smoothness ntawm lub phaj nto yog tsis zoo, lub number case txheej thiab siab yuav tsum tau rau printing yog loj; ntawm qhov tsis sib xws, nws yog me me. Yog tias cov zinc phaj siv rau kev luam ntawv, vim nws cov cwj pwm tsis zoo thiab qhov tsis zoo ntawm lub ntsej muag, tsuas yog ua kom lub siab ntawm cov ntawv luam tawm thiab cov tuab ntawm cov number case txheej tuaj yeem ua tiav cov txiaj ntsig ntawm tag nrho cov luam ntawv number case txheej, tab sis qhov no tuaj yeem yooj yim ua rau smearing, yog li nws tsis tsim nyog siv zinc phaj Xim luam ntawv cov khoom nrog ntau tshaj octave hom. Vim hais tias cov photosensitive resin phaj muaj zoo nto gloss, mos zoo nkauj, zoo flatness thiab number case affinity, nws printing number case txheej yog corrosively thinned, thiab nws tseem tuaj yeem ua tiav cov txiaj ntsig luam ntawv zoo dua, thiab nws tsis yooj yim rau smudge. Yog li ntawd, photosensitive resin daim hlau yuav tsum tau siv thaum luam tawm cov duab loj.
4. Zam kom tsis txhob muaj av nyob rau sab nraub qaum los ntawm kev luam ntawv number case txheej thickness
Txhawm rau txiav txim siab seb cov txheej txheem luam ntawv yog qhov nruab nrab, lub hauv paus tseem ceeb yog lub phaj luam ntawv sib npaug sib npaug, lub phaj sib npaug sib npaug kom ua tiav tsis muaj hauv qab, tsis muaj kev luam ntawv cuav, thiab xim ntawm cov khoom luam tawm zoo ib yam nrog cov qauv sau ntawv. Yog tias lub tshuab luam ntawv tsis sib npaug lossis tsis txaus, qhov ci ntawm cov ntawv luam tawm tsis zoo, lub xim ntawm cov ntawv luam tawm yog tsaus, thiab xim xim xim hloov maj mam, nws yuav yooj yim ua rau kev txiav txim siab tsis raug ntawm cov ntawv luam ntawv txheej tuab. Lub sijhawm no, yog tias koj dig muag nce tus number case ntim, Yog tias txheej number case tuab dhau lawm, sab nraum qab ntawm cov khoom luam tawm yuav raug smeared.
5. Zam kev luam ntawv qias neeg los ntawm kev ua haujlwm tsis raug
(1) Kev hloov tsis raug ntawm tus number case roller, ntau dhau los yog tsis sib xws ntawm tus number case
Thaum muaj qhov sib txawv loj lossis eccentricity ntawm tus cwj mem rau lub taub hau thiab lub qhov taub vim hnav; Thaum lub elasticity ntawm tus number case rau cov gel ua tsis zoo, tus number case rau cov menyuam yuav tsis sib npaug ntawm cov phaj nto thaum lub sij hawm dov thiab txhuam txhuam, uas yog ib qho yooj yim ua rau lub zos number case txhuam ntawm lub phaj nto. Tsis sib npaug, nyias txheej txheej tshwm. Tsis tas li ntawd, yog tias tus number case rau cov menyuam tau hloov siab dhau los lossis ib lub taub hau siab dhau lawm, nws yog ib qho yooj yim uas yuav ua rau tsis txaus los yog tsis sib xws ntawm cov number case txheej ntawm lub phaj nto. Nyob rau lub sijhawm no, yog tias tus number case ntim tau nce qhov muag tsis pom, cov number case txheej ntawm ib feem phaj saum npoo yuav thicker thiab ua rau smearing. Yog li ntawd, thaum luam ntawv loj-thaj phaj cov khoom, tus number case rau cov menyuam yuav tsum muaj siab precision, zoo roundness, tsim nyog softness thiab hardness ntawm roj hmab cov menyuam, uniform kev sib cuag ntawm tus number case roller thiab inking roller, thiab qhov siab hloov yuav tsum yog. kom txo tau qhov tshwm sim ntawm smearing ntawm cov khoom luam tawm. caij nyoog.
(2) Kev txais cov ntaub ntawv tsis raug
Thaum luam ntawv thiab tau txais daim ntawv, koj yuav tsum tau kho lub kaum sab xis thiab qhov siab ntawm cov ntawv poob raws li qhov loj ntawm cov khoom luam tawm thiab qhov hardness ntawm daim ntawv. Txwv tsis pub, ntug ntawm cov ntawv luam tawm yuav yooj yim kov cov cim ntawm cov ntawv luam tawm dhau los, uas yuav ua rau cov number case rau saum npoo ntawm cov khoom luam tawm. Tsis tas li ntawd, cov ntawv luam tawm yuav tsum tau ua tib zoo saib xyuas kom tsis txhob muaj cov ntawv luam tawm sab saud thiab qis qis ntawm kev txav thiab kev sib txhuam ua rau cov nplaum. Qhov kom muaj nuj nqis ntawm cov ntawv ziab khaub ncaws yuav tsum tau ntswj raws li tus number case-tau txais kev mob ntawm daim ntawv luam ntawv, thiaj li tiv thaiv kom tsis txhob hnyav thiab nplaum.
(3) Kev txhawb nqa hauv qab ntawm lub phaj luam ntawv tsis yog khoom thiab lub siab tsis sib xws
Cov khoom siv plywood tsis muaj zog txaus, thiab compression deformation coefficient yog loj. Yog tias cov khoom siv no yog siv los ua kev txhawb nqa hauv qab ntawm lub phaj luam ntawv, lub siab thiab lub thickness ntawm tus number case txheej yuav tsum tau nce, yog li nws yog ib qho yooj yim los ua kom cov khoom luam ntawv nplaum. Yog li ntawd, nws yog qhov zoo tshaj kom tsis txhob siv cov plywood hauv qab kev txhawb nqa thaum luam ntawv rau hauv av. Lub rooj sib nqus phaj lossis lwm cov hlau hauv qab yuav tsum tau siv los ua cov ntawv luam tawm txheej nyias thiab tsis kim, uas yog qhov zoo los tiv thaiv kev ua kom tsis txhob lo thiab staining.
(4) Cov ntawv yog acidic heev, huab cua ntub, thiab cov khoom luam tawm tsis yooj yim kom qhuav.
Thaum luam ntawv nrog cov ntawv offset lossis qee cov ntawv xov tooj hauv tsev, vim tias cov ntawv luam ntawv txheej yog tuab thiab cov ntawv yog acidic, cov number case txheej tsis yooj yim kom qhuav, thiab nws kuj yog smearing. Lub sijhawm no, cov roj qhuav yuav tsum tau muab ntxiv rau hauv tus cwj mem kom tsis txhob muaj cov khoom luam tawm los ntawm kev nplaum.
(5) Kov lub crease ntawm daim ntawv kom muaj kev sib txhuam ntawm cov khoom luam tawm
Thaum luam ntawv coated ntawv, vim hais tias saum npoo ntawm daim ntawv yog tus du, yog tias daim ntawv crease tseem ceeb, nws yog ib qho yooj yim rau rub tawm ntawm cov luam ntawv thiab ua rau stickiness. Yog li ntawd, khob daim ntawv yuav tsum tau mastered raws li tus qauv layout thiab ntawv yam ntxwv. Rau cov ntawv tuab tuab, sim tsis txhob khob, thiab tsuas yog siv txoj kev kneading nce lossis nqis, thiab knead daim ntawv ncaj thiab ruaj.
