1. Kev ua luam siab ua rau qhov khoom neeg poob haujlwm nce
Kev hloov ntawm tus cwj mem thiab kev xa tawm ntawm luam tawm thaum luam ntawv yuav tsum muaj lub tshuab luam ntawv uas tsis tsim nyog, thiab deformation ntawm cov dots thiab deformation ntawm daim pam los ntawm tus cuj pwm ua kom deformation thiab nce ntawm cov dots. Yog li, thaum luam qhov PS version, nws yog qhov yuav tsum tau muab cov qauv sib txawv (cov tshuab luam ntawv sib txawv nyias muaj qhov txawv ntawm qhov txiaj ntsig tau txais txiaj ntsig) xaiv lub sij hawm tsim nyog, yog li ntawd cov dots nyob rau PS phaj yog me ntsis me tshaj cov pov thawj, thiab cov teeb meem luam tawm yuav ua tau raws li cov pov thawj.
2. Tsis zoo los ntawm cov ntawv luam tawm pluag tsis zoo
Ib txhia ntawm cov PS versions muaj thicker meshes, thiab ib txhia muaj poorer photosensitivity. Nws yog ib qho yooj yim tsim ib qho tsaus muag nyob ib ncig ntawm cov teeb meem tom qab kis. Tom qab ntawm PS daim ntawv cim, qhov tsaus muag qis kuj yog sau. Cov nyhuv sij yog qhov nce qhov chaw, ua rau cov hnub poob kom nce, thiab nws yog qhov yuav tsum hloov lub PS phaj nrog kev zoo dua.
3. Hloov twj ntaus kab yog tsis hloov kho
Txoj hauj lwm txheeb ze ntawm tus cwj mem xauv hloov, thiab lub zog ntawm lub caj dab thiab lub khoov kuj hloov, uas ua rau muaj kev puas tsuaj rau tus cwj pwm hloov kev sib raug zoo. Qhov siab ntawm cov phaj cov phom yog hnyav, qhov deformation ntawm lub phaj loj loj, txoj kab uas hla ntawm lub rubber roller yog thinner, txoj kab ceev ntawm cov phaj cov phom thiab cov phaj cov phom yog inconsistent, thiab cov chaw mesh elongated hauv qhov chaw ntawm sab sauv ntawm cov laib los ua rau lub cev deformation.
4. Pam dej yog tuab heev los yog muag heev
Daim pam no dhau heev lawm los yog muag muag kom siab ntawm lub phom lub tog raj kheej thiab pam poom, pam lub tog raj kheej thiab lub tswv yim kheej kheej kheej kheej (tus menyuam lub tog raj kheej yog qhov hloov tus menyuam thiab lub tswv yim lub tswv yim), thiab cov pauv qhov pauv ntawm daim pam Qhov dav ntawm qhov sib tiv tauj yog loj, qhov tsis zoo ntawm qhov taw qhia tsis yog qhov tsim nyog, qhov reproducibility ntawm tus dot yog pluag, thiab qhov nce qhov siab tseem ceeb.
5. Tus lej ntawm tus lej yog loj heev
Nyob rau hauv tej yam kev mob uas zoo tag nrho, lub thickness ntawm lub tsho cwj pwm ntim yuav tsum tau tswj tsis pub dhau 25 μm. Raws li tus nqi ntawm tus number case yog nce, thickness ntawm tus number case zaj duab xis yog nce, thiab qhov sib cais quab yuam kuj yog nce ntau zog. Cov cwj mem ntau dhau tsis tuaj yeem pauv mus los ntawm lub substrate, thiab tus number case yog tsim nyob rau ntawm lub phaj printing thiab daim pam, thiab tus cwj pwm pib kis, ua rau cov lus qhia kom nce thiab txawm tias ib qho muab tso rau.
6. Kev tswj tsis sib haum ntawm daim ntawv no tsis zoo los yog pam wrapping yog inconsistent
Yog hais tias daim ntawv nro tsis zoo tswj los yog daim pam tsis sib haum, qhov luam tawm ntawm cov xim dhau los yuav raug muab tso rau ntawm daim pam ntawm qhov xim ntxiv tom ntej, thiab daim duab yuav tshwm sim, thiab cov duab xa mus rau ntawm daim ntawv tseem yuav tshwm sim los ua ob sab thiab qhov muag plooj, thiab cov dots yuav loj dua. .
7. Ink viscosity yog tsawg thiab muaj fluidity heev
Cov kua roj carbon dioxide yog ib yam tseem ceeb heev, cov thixotropic thiab yield qhov tseem ceeb me me, cov viscosity tsawg dhau, tus number case ntev dhau, thiab fluidity muaj zog heev, thiab ntau dua dampening kua yuav tsum tau lwv nrog nws thaum luam ntawv. Emulsified tus cwj pwm yog yooj yim mus kis rau ntawm PS phaj, uas nyhav ua rau cov hnub poob kom nce. Hloov mus rau lub substrate tsis conducive rau solidification ntawm tus number case, thiab ib cov duab ntshiab tsis tuaj yeem tau txais.
Ib txoj hauv kev zoo los tswj qhov kev nce nqi
Txawm tias qhov txiaj ntsim ntawm qhov poob yog kev tsis pom zoo, nws tswj tau. Raws li ib txwm muaj, qhov zoo ntawm cov ntaub ntawv yog qhov tsawg tshaj li 12%, qhov sau luam tawm tsawg dua 18%, thiab cov ntawv xov xwm luam tawm yog tswj li ntawm 35% (feem ntau yog 50% dot). Hauv txoj kev ua ntau yam, nws tuaj yeem raug tswj tau los ntawm cov hauv qab no.
1. Xaiv cov kev tshaj tawm zoo, tswj kev tsim nyog ntawm lub sij hawm raug mob thiab kev tsim tawm
Cov ntawv luam tawm tau meej meej thiab cov dots yog ib qho muaj zog, yog li ua kom muaj kev hloov cov nyom, thiab xyuas kom cov paib muaj lub siab ntev. Feem ntau, 5% ntawm qhov chaw tawm tsis ploj, thiab 95% ntawm qhov chaw tawm tsis plooj.
2. Tswj ntau yam kev ntxhov siab hauv kev tsim nyog
Lub siab ntawm lub phom lub tog raj kheej thiab daim pam lub pawm npab yog tswj ntawm 15 thiab 20 filaments, thiab qhov siab ntawm ob lub thawv pliav yog tswj los ntawm 22 mus rau 28 filaments, thiab ob daim khauj khaum ntawv tseem ceeb rau cov phaw twj, thiab lub dav hlau tsawg dua 100 hli. Cov ntawv luam tawm ntawm cov tub ntxhais kawm ntawv thiab cov phaj khij nyiab muaj qhov dav ntim ntawm 5 txog 6 hli, thiab cov luam yeeb thiab cov phom khawm muaj lub kab uas muaj 100 hli lossis ntau dua muaj qhov dav ntim ntawm 6 txog 7 hli.
3. Khwv yees tus cwj mem thiab dej tshuav ntawm luam ntawv
Hauv cov txheej txheem luam ntawv, yog tias cov dej tsis loj heev, tus nqi ntawm lub ploj muab nkag rau qhov tsim yuav nce ntxiv, tus lej txheej yuav ua rau tuab, thiab tus lej yuav raug emulsified tiag, ua rau muaj kev npau taws thiab npau taws. Hauv cov txheej txheem, kom txo tau cov khoom pov tseg pib, cov dej theem feem ntau nce mus rau 150% ntawm tus nqi qub thaum lub tshuab qhib. Thaum lub luam ntawv tsis muaj dab tsi, cov dej ntau yuav tsum maj mam txo mus rau qhov qub nqi kom pom tseeb tias cov duab nruj meej, nplua thiab ci ntsa iab.
4. Ua kom tswj cov ntsiab lus ntawm dampening tov
Kev tswj ntawm cov concentration ntawm qhov ciav kua plays plays lub luag haujlwm tseem ceeb hauv qhov nyiaj tshuav ntawm tus number case thiab qhov zoo ntawm cov ntawv luam tawm. Ib qho kev tsis haum ntawm dampening daws tau sai sai ntxuav cov "av" nyob ib ncig ntawm cov dots. Yog hais tias cov concentration ntawm dampening kua yog tsawg, tus number case ncig lub teev yuav tsis tau muab tshem tawm, uas yuav ua rau cov teev kom nce, thiab muab tshuaj txhuam yuav ua rau muab tshuaj; Yog hais tias cov concentration ntawm dampening tov yog siab dhau, lub phaj luam ntawv ntawm PS phaj yuav raug txo thiab lub dampening daws yuav ntau heev ntawm pov tseg. Feem ntau, cov pH ntawm cov tshuaj tsis haum yog tswj ntawm 4.8 rau 5.3, thiab cov conductivity yog tswj ntawm 800 txog 1200 μs.
5. Tswj cov ntawv nro
Muaj ob yam tseem ceeb rau kev tswj nruj. Ib qho yog qhov nrhav kev ua los ntawm daim ntawv tuav nrog lub nro tswj qhov system, thiab lwm qhov yog qhov nro theem nrawm los ntawm kev hloov mus rau qhov tsis sib haum xeeb tom qab luam ntawv. Raws li ib txwm muaj, kom paub tseeb tias qhov nro nrab nrawm dua me ntsis ntawm qhov nro ntawm daim ntawv nyob rau hauv ntawv luam, qhov teeb tseg tuaj yeem tsim tau zoo dua thiab xim dhau los (feem ntau yog dub) tsis yog blooming.
