【1】 Taw qhia txog kev luam tawm kev luam ntawv
Vijtsam luam ntawv belongs rau orifice phaj luam ntawv. Cov kev nkag siab yooj yim yog siv cov kua nplaum kua nplaum txhawm rau txhaws rau thaj chaw tsis pom kev ua si, tawm cov duab lossis ntawv sau uas xav tau, thiab hloov tus number case rau hauv txheej los ntawm lub qhov ntawm orifice phaj los ntawm lub siab kom tsim tau cov duab lossis cov ntawv sau.
Vijtsam luam tawm substrate tuaj yeem yog ntawv, ntoo, iav, hlau, yas thiab lwm yam muaj ntau yam ntxiv.
Cov ntawv thov luam ntawv siv dav hauv lub neej txhua hnub suav nrog cov lus qhia ntawm cov khoom lag luam, cov qauv zoo nkauj ntawm cov khoom siv hauv tsev, qauv T-lub tsho, cov paib qhia, phau ntawv npog, ntawv tshaj xo, daim npav lag luam, thiab lwm yam
【2】 Txuj ci thev naus laus zis los ntawm luam ntawv luam ntawv
Cov txheej txheem dav dav yog raws li hauv qab no:
Cov tshuab luam ntawv luam tawm cov ntawv luam tawm → tsim cov zaj duab xis, tshuaj ntsuam cov duab → xim luam ntawv → cov tshuab luam ntawv xim
01, npo luam ntawv cov ntaub ntawv tsim tawm;
Nws' s luam tawm silk ntau daim ntawv luam tawm xa los ntawm tus tsim qauv mus rau cov chaw tsim khoom, vim tias kev tshuaj ntsuam luam ntawv luam tawm yog feem ntau monochrome lossis multicolor overprint, yog li peb xav tau los cuam tshuam nrog daim ntawv thaum pib theem ntawm kev tsim. Vector cov ntaub ntawv yog hom ntawv zoo tshaj plaws, xws li aicdpspdf. Yog tias cov duab kos me lossis cov ntsiab lus txhais tau tsawg, nws tseem OK los muab cov duab txhais cov duab siab.
Hierarchical tsim cov ntaub ntawv
Vim tias qhov kev txiav txim siab me me ntawm kev tshuaj ntsuam luam ntawv tuaj yeem tsuas yog monochrome printing thiab monochrome overprint, tus tsim qauv xav tau kev ua cov txheej txheem nyob rau ntawm daim ntawv, piv txwv li, dub thiab liab / dub thiab xiav yuav tsum sib cais luam ntawv luam tawm ob zaug.
Tseem muaj qee yam kev tsim ua yeeb yam, tsis tas yuav ua kom muaj kev sib txuam, tuaj yeem yog ntau xim xim synchronous npo luam ntawv
【3】 Teeb meem thiab cov kev daws teeb meem hauv luam ntawv number case
Ua npuas ncauj:cov laj thawj yog vim li cas luam ntawv viscosity yog siab dhau, lub ziab kom nrawm dhau, lub phaj thiab cov txheej nruab nrab yog sib cais nrawm dhau, kab ntawv tsis zoo, tus cwj mem nws tus kheej muaj teeb meem, thiab lwm yam, yog li cov coj ntsuas yuav raug coj mus rau kho raws li cov txheej txheem saum toj no, lossis tus neeg saib xyuas kev tsim nyog tuaj yeem ntxiv tau thiab tus number case tuaj yeem hloov tau.
2. Thaiv:qhov laj thawj yog vim tias kev luam ntawv nrawm nrawm dhau heev, luam ntawv viscosity ntau dhau, qhov chaw tsis siv tsis raug, qhov chaw luam ntawv raug tshuab los ntawm cua, tus number case zoo yog qhov tsis tsim nyog lossis lub impurities raug coj. Kev ceev kom qhuav yuav tsum tau kho kom haum los yog tus number case yuav tsum tau hloov.
3. Pinhole:vim hais tias cov txheej txheem qis dhau, tus luam ntawv nto muaj cov roj lossis impurities, thiab tus number case nws tus kheej tsis zoo, yog li cov dej hauv av yuav tsum yog ua ntej luam ntawv, thiab tus neeg sawv cev qib lossis tus number case zoo yuav tsum tau hloov.
4. Cov nplaum tsis zoo:qhov laj thawj yog tias tus number case tsis raug xaiv qhov tsim nyog, kev kho ua ntej luam ntawv tsis txaus, lub hauv qab muaj impurities, lub tshuab ziab qhuav thiab lub sijhawm tsis txaus, qhov tshuaj ntawm cov tshuaj ntxiv, cov tshuaj tua kab mob thiab cov kab mob qhuav tsis tsim nyog, thiab lub hauv paus xim yog solidified dhau lawm thaum ob-tivthaiv number case yog teem.
Vim tias PE, PP, tus tsiaj, txhuas ntawv ci thiab lwm cov ntaub ntawv muaj cov tshuaj lom neeg tsis tshua muaj zog lossis du dhau, lawv feem ntau kho nrog lub txim taws, nplaim hluav taws, cov kua qaub muaj zog tawm los txhim kho qhov nro ntawm luam ntawv nto. Tom qab tus number case zaj duab xis ntawm ob-tivthaiv tus number case raug kho, vim qhov cov tshuaj lom neeg, nws yog qhov nyuaj rau hla kev txuas rau zaj duab xis number case tuab. Cov zaj duab xis uas kho tag nrho yog qhov nyuaj ua kom muaj teeb meem los ntawm cov kuab tshuaj. Yog li ntawd, thaum cov xim ua tiav xim luam ntawv tiav, hauv qab rooj xim tuaj yeem luam tawm tom qab ziab, thiab lwm yam tuaj yeem hloov kho los ntawm cov qauv coj.
5. Teeb Duab:qhov laj thawj yog tias viscosity yog siab dhau, lub ziab kom nrawm dhau, thiab cov roj av thiab cov kuab tshuaj siv hauv tus number case tsis tau sib phim. Siv cov kuab tshuaj uas tsim nyog, kho qhov tsim nyog viscosity lossis hloov tus number case zoo.
6. tsiv teb tsaws, xim:qhov laj thawj yog tias tus number case tsis siv tsim nyog, tshwj xeeb tshaj yog nrog coob tus plasticizer mos zaj duab xis, uas ntau dua yuav mus, thiab cov kua mem tsim nyog yuav tsum tau xaiv.
7. Dawb los yog pos huab ntawm luam ntawv nto:qhov laj thawj yog tias qhov tsis meej muaj cov dej, qhov cua kub ntawm qhov chaw luam ntawv, los yog tus luam ntawv nws tus kheej yuav tsis zoo.
