Vijtsam cov khoom ua suab yog cov tseem ceeb hauv kev tswj kom zoo ntawm cov xim luam ntawv. Yuav kom ua tiav cov khoom zoo zoo ua haujlwm zoo nkauj luam tawm, tswj kev tswj hwm thaum lub sijhawm tsim khoom yog qhov tseem ceeb. Hauv qab no yog cov kev txiav txim siab tseem ceeb rau kev ua kom tiav cov txiaj ntsig zoo tshaj plaws:
1. Xaiv cov khoom siv hauv ob sab phlu nrog lub hardness tsim nyog kom ua kom meej meej thiab du dot luam me ntsis.
Whether using letterpress or offset printing processes, the softness or hardness of the backing material significantly affects dot printing quality. Kev muag muag ntau dhau yuav ua rau muaj kev deformation thiab nthuav dav. Txhawm rau kom meej meej thiab kev ua tub tu tu me me ntawm cov dots me me, ib qho nruab nrab thiab me ntsis nyuaj cov khoom yuav tsum tau siv. Cov ntaub ntawv tsim nyog suav nrog cov ntawv insulating, cardstock, kraft daim ntawv, thiab cov ntawv ntim. Hloov pauv, ntaub qhwv ntsej muag, ntaub zoo, thiab cov ntawv xov xwm yog softer phlings uas yuav deform hauv siab.
2. Hloov kho luam ntawv siab rau theem siab.
Ob tsab ntawv Letterpress thiab Offset luam ntawv cia siab rau kev hloov siab rau kev hloov cov ntawv luam tawm. Kev ua kom ntau dhau los yuav ua rau dot nthuav dav thiab deformation, nrawm phaj hnav. Tsis tshua muaj siab ua rau cov lus tsis zoo, tawg, thiab tsis muaj tseeb duab txheej. Lub tshuab luam ntawv siab yuav tsum ua kom muaj kev sib tiv thaiv thiab sib tham nrog cov thooj voos kheej kheej thiab nruab nrab ntawm lub tog raj kheej (hauv cov ntawv luam tawm (hauv cov ntawv sau ua ke thaum lub sijhawm pom kev.
3. Kho kev tiv thaiv kev sib chwv nruab nrab ntawm cov kua mem thiab cov ntawv luam tawm thiab xaiv cov roj hmab uas tsim nyog nrog hardness.
Tus number case ua haujlwm ua tus thawj nruab nrab rau kev hloov mem. Kev hloov kho kom raug ntawm nws kev tiv tauj siab nrog lub tshuab luam ntawv yog qhov tseem ceeb rau dot luam ntawv zoo. Ntau dhau siab ua rau yuav ua rau phaj hnav thiab dot deformation, thaum tsis muaj qhov txiaj ntsig zoo hauv kev tsis sib xws thiab tsis paub txog luam ntawv.
4. Siv cov kua txob siab rau luam tawm.
Tsawg-fineness number case, cov cim los ntawm coarse xim cov lus, feem ntau ua rau muaj kev sib deev fuzzy thiab txo cov luam ntawv phaj durability. Nws kuj tseem yuav ua rau phaj nplaum tsis xws luag. High-finess nyob rau hauv cov kua zaub tsib, nrog siab dua siab, ua kom pom tseeb thiab tag nrho cov chaw ua haujlwm tshwj xeeb ntawm cov ntaub ntawv luam tawm.
5. Kom zoo kho cov kua paug viscosity thiab fluidity.
High-viscosity number case yuav ua rau tsis ncaj rau hauv qhov chaw hloov pauv tsis sib xws, frayed dots, thiab phaj phaj smudging. Low-viscosity number cas yog nquag rau emulsification, ua rau saum cov av thiab lwm yam teeb meem. Ink fluidity yog ze ze rau viscosity; Cov kua mem tsis muaj hom xim muaj qis dua muaj cov xim tsawg dua, thaum tsis muaj viscosity ink muaj ntau lub funcience. Tsis txaus fluidity tuaj yeem ua rau kev sib deev tsis tiav thiab cov suab tsis zoo, hos cov fluently ntau dhau ntawm kev daws teeb meem thiab tag nrho. Cov tshuaj ntxiv xws li nyob rau hauv cov txias txias tuaj yeem siv los kho viscosity thiab fellityity thaum tsim nyog.
6. Xaiv cov ntawv tsim nyog rau cov mesh luam tawm zoo.
Daim ntawv smoothness ncaj qha cuam tshuam cuam tshuam dot luam ntawv zoo. Cov ntawv tsis zoo cov ntawv luam tawm tsis txhob muaj cov teeb meem raug txawv vim yog cov chaw concave uas ua tsis tau cov teeb meem me me, ua rau muaj kev cuam tshuam loj. Txog kev tshuaj ntsuam zoo luam ntawv, nws yog qhov tseem ceeb rau kev xaiv cov ntawv nrog cov ntawv luam zoo, xws li coated ntawv lossis iav phaib, los ua kom ntseeg tau cov ntawv sau cia ntawm cov ntawv sau qub.
7. Cov cuab yeej siv precision los tiv thaiv kev deformation dot.
Cov cuab yeej ua ntej txiav txim cov khoom luam ntawv zoo. Cov cuab yeej siv tsis zoo nce ntxiv thiab tau txais cov khoom lag luam zoo. Kev tu lubrication tsis tu ncua, suav nrog lubrication ntawm cov khoom tseem ceeb xws li lub zog, ncej taub hau, thiab ua kom muaj txiaj ntsig zoo. Qhov no txwv tsis pub muaj cov teeb meem uas muaj kev nthuav dav, mottling, lossis ob npaug ntawm kev ua kom tshwm sim los ntawm cov tshuab hnav.
8. Tswj luam ntawv ceev kom tsim nyog los txhim kho cov ntawv sau npe.
Caw kaw cov tshuab luam ntawv muaj kev hloov kho lub tshuab ceev. Ultra-kev kub ceev luam ntawm kev luam ntawm cov ntxaij vab tshaus tuaj yeem ua rau kev sau npe tsis ruaj khov thiab tsis muaj tseeb. Kev Luam Ntawv Hluav Taws Xob Kom Yooj Yim Kom Yooj Yim Rau Cov Ntawv Sau Npe thiab Siv Lub Tshuab Kev Ruaj Ntsig, ua kom muaj cov ntawv ruaj khov ncaj ncees thiab cov khoom lag luam zoo ib yam nkaus.
9. Xaiv cov tshuab luam ntawv raws cov luam ntawv cov cim muaj teeb meem los xyuas kom zoo.
Cov kev tsim qauv pom tau pom tias xaiv cov tshuab luam ntawv haum raws li cov ntawv luam tawm muaj teeb meem txhim kho cov khoom lag luam zoo. Rau cov xim ntau txheej txheem screen ua suab nrov, muaj ntau hom xim yuav tsum tau ua ntej los txhim kho cov ntawv sau npe.
Hauv kev xaus, ua tib zoo mloog rau txhua qhov kev ntsuas ntawm cov txheej txheem tsim khoom, tsis yog tiv thaiv ntau yam tsis xws luag, txhim kho cov kev ua haujlwm ntau dua.
