Cov npo luam ntawv yog tshuaj ntsuam luam ntawv phaj nrog cov duab thiab ntawv sau, uas yog ua raws cov xov paj ntawm cov xov paj thiab ua los ntawm cov txheej txheem luam tawm.
Qhov yooj yim tsib yam ntawm kev tshuaj ntsuam luam ntawv yog raws li nram no:
Vijtsam luam tawm
Screen silk screen scraper
③ mem kua lossis kua nplaum
Npo tshuab luam ntawv / chaw nres tsheb luam ntawv
Qhov no yog qhov peb feem ntau xav tau nyob hauv cov txheej txheem ib txwm ntawm cov tshuaj ntsuam silk luam ntawv. Nws tuaj yeem hais tias nws yog tus qauv tseem ceeb tshaj plaws hauv kev ntxhua khaub ncaws npo luam ntawv.
Lub hauv paus ntsiab lus ntawm kev tshuaj ntsuam luam ntawv yog raws li hauv qab no:
Kev tshuaj ntsuam luam ntawv yog ua raws li lub hauv paus ntsiab lus tias cov mesh ntawm daim duab ntu yog number case permeable thiab cov mesh ntawm qhov tsis yog graphic yog number case impermeable. Thaum luam ntawv, tus number case yog nchuav mus rau ib qho kawg ntawm lub vijtsam luam ntawv phaj, thiab cov scraping scraper yog siv los thov cov kev ntsuas siab ntawm tus number case ntawm lub vijtsam luam ntawv phaj, thaum tsiv mus rau lwm qhov kawg ntawm lub vijtsam luam ntawv phaj.
Tus number case yog nrawm mus rau txoj kab hauv qab los ntawm scraper los ntawm cov mesh ntawm qhov nraaj feem hauv kev txav. Vim hais tias cov ntawv nplaum ua haujlwm ntawm tus cwj mem, qhov kev luam tawm yog tsau nyob rau hauv qee yam. Thaum lub sijhawm luam ntawv, cov scraper ib txwm nyob rau hauv kab sib txuas nrog lub vijtsam phaj thiab lub hauv qab, thiab cov xov tooj sib kis tau txav nrog tus scraper tsiv. Vim tias muaj qee qhov sib txawv nruab nrab ntawm lub vijtsam phaj thiab lub hauv qab, phaj npo tsim cov tshuaj tiv thaiv tawm ntawm lub scraper los ntawm nws tus kheej nruj, Cov tshuaj tiv thaiv no hu ua thim rov qab.
Vim tias qhov cuam tshuam ntawm resilience, lub vijtsam luam ntawv phaj thiab cov hauv qab yog tsuas yog hauv kev sib txuas xov tooj ntawm tes, thaum lwm seem ntawm lub vijtsam luam ntawv phaj yog cais cov substrate. Yog li ntawd tus number case thiab tshuaj txhuam kev txav, kom ntseeg tau tias cov ntawv luam qhov ntev thiab tsis txhob txhuam cov tawv qias neeg. Thaum lub scraper tau nqa tom qab scraping tag nrho cov kab ntawv, lub vijtsam phaj kuj tseem nqa, thiab tus number case yog maj mam scraped rov qab mus rau qhov chaw qub, uas yog luam ntawv stroke.
Cov yam ntxwv tseem ceeb ntawm kev tshuaj ntsuam luam ntawv:
① Vijtsam luam ntawv tuaj yeem siv ntau hom mem kua. Ntawd yog: oily, dej-raws, hluavtaws cob emulsion, hmoov thiab lwm hom number case.
Qhov txheej yog qhov muag muag. Vijtsam luam ntawv tsis yog tsuas yog tsim rau luam ntawv ntawm daim ntawv, daim ntaub, tawv thiab lwm cov ntawv mos, tab sis kuj tsim rau luam tawm ntawm cov ntawv nyuaj, xws li iav, ceramics, cov paib thiab lwm yam.
Cov tshuab luam ntawv luam tawm muaj lub zog luam tawm me me. Vim tias lub siab poob qis siv hauv luam ntawv, nws tseem tsim rau luam tawm ntawm lub khw lub cev tsis yooj yim.
Ink Thick number case txheej, muaj zog tiv thaiv.
Nws tsis txwv los ntawm daim duab saum npoo thiab thaj chaw ntawm cov substrate. Nws tsis yog tsuas yog tsim rau luam tawm ntawm cov khoom me, tab sis kuj tsim nyog rau luam tawm ntawm cov khoom loj. Qhov txheej txheem luam ntawv no muaj qhov hloov tau yooj yim thiab siv tau ntau yam.
