Kev luam ntawv tshuaj ntsuam ua rau muaj xim sib txawv vim yog cov yam no

Vim li cas kev luam ntawv tshuaj ntsuam thiaj tsim cov xim sib txawv? Yog tias peb tso tseg qhov sib xyaw ntawm ntau xim thiab xav txog tsuas yog ib xim xwb, nws yuav yooj yim dua los tham txog cov laj thawj ntawm cov xim sib txawv. Tsab xov xwm no qhia ntau yam uas cuam tshuam rau qhov sib txawv ntawm cov xim hauv kev luam ntawv tshuaj ntsuam. Cov ntsiab lus yog rau kev siv los ntawm cov phooj ywg uas yuav thiab muab cov khoom siv ntim khoom Youpin:

Hauv qab no yog qee yam uas ua rau muaj xim txawv hauv kev luam ntawv: kev npaj kua mem, kev xaiv mesh, kev nruj ntawm mesh, kev siab, kev ziab, cov yam ntxwv ntawm cov substrate, cov xwm txheej soj ntsuam, thiab lwm yam.

 

01 Kev npaj kua mem
Kev sib xyaw xim ntawm cov kua mem Yog tias cov xim ntawm cov kua mem siv yog cov xim txheem, qhov ua rau muaj xim sib txawv loj tshaj plaws yog kev ntxiv cov kuab tshuaj xws li roj sib xyaw xim rau hauv cov kua mem. Hauv lub chaw ua haujlwm uas muaj cov khoom siv tswj xim zoo, cov kua mem tuaj yeem sib xyaw raws li cov khoom siv tswj. Txawm li cas los xij, rau feem ntau cov tuam txhab luam ntawv, nws tsis yooj yim sua kom muaj cov chaw no. Lawv tsuas yog vam khom kev paub ntawm cov neeg ua haujlwm txawj thaum sib xyaw xim.

Feem ntau, cov roj kho cov kua mem yuav raug ntxiv rau hauv kom cov kua mem zoo dua rau kev luam ntawv. Txawm li cas los xij, thaum cov roj kho tau ntxiv rau hauv cov kua mem, qhov concentration ntawm cov xim hauv cov kua mem yuav hloov pauv, uas yuav ua rau muaj kev hloov pauv ntawm cov yam ntxwv xim ntawm cov kua mem thaum lub sijhawm luam ntawv. Tsis tas li ntawd, cov kuab tshuaj ntau dhau hauv cov kua mem yuav tsim cov kua mem nyias tom qab ziab, uas yuav txo qhov ci ntawm cov xim.

Tseem muaj teeb meem ntawm cov kua mem uas raug diluted ua ntej siv cov kua mem. Piv txwv li, cov neeg ua haujlwm hauv lub khw muag kua mem txiav txim siab raws li lawv cov mis thaum sib tov lossis diluting cov kua mem. Qhov no ua rau muaj kev hloov pauv xim tsis zam. Yog tias cov kua mem tau sib tov ob peb hnub dhau los, Yog tias koj luam tawm nrog cov kua mem zoo, cov xim uas tshwm sim los ntawm qhov xwm txheej no yuav pom tseeb dua. Yog li ntawd, nws yuav luag tsis yooj yim sua kom tsis txhob muaj xim ploj mus.

 

02 Kev xaiv mesh
Yog tias koj xav tias qhov loj ntawm lub mesh ntawm lub vijtsam yog tib qho uas cuam tshuam rau kev hloov pauv number case, koj yuav ntsib ntau yam teeb meem. Mesh txoj kab uas hla thiab wrinkles kuj cuam tshuam rau kev hloov pauv number case. Feem ntau, cov number case ntau dua txuas rau cov qhov number case ntawm lub vijtsam, cov number case ntau dua yuav raug xa mus rau lub substrate thaum lub sijhawm luam ntawv.

Yuav kom kwv yees ua ntej seb txhua lub mesh muaj pes tsawg tus number case tuaj yeem hloov pauv tau, ntau tus neeg muab khoom siv screen muab qhov theoretical ink transfer volume (TIV) ntawm txhua lub mesh. TIV yog ib qho parameter qhia txog qhov loj ntawm qhov ink transfer ntawm lub screen. Nws yog hais txog qhov ntau ntawm cov number case transfer hauv ib qho twg Yuav muaj pes tsawg tus number case yuav raug hloov pauv los ntawm txhua lub mesh raws li cov xwm txheej luam ntawv tshwj xeeb. Nws chav tsev yog qhov ntim ntawm number case ib chav tsev.

Yuav kom paub tseeb tias cov suab sib xws hauv kev luam ntawv, nws tsis txaus kom khaws tus lej mesh ntawm lub vijtsam tsis hloov pauv, tab sis kuj tseem yuav tsum xyuas kom meej tias txoj kab uas hla ntawm lub vijtsam thiab nws qhov nthwv dej tseem nyob ruaj khov. Kev hloov pauv ntawm txhua qhov parameter ntawm lub vijtsam yuav ua rau muaj kev hloov pauv ntawm qhov tuab ntawm cov zaj duab xis number case thaum luam ntawv, ua rau muaj kev hloov pauv xim.

 

03 Kev ntxhov siab ntawm lub cev
Yog tias qhov nro ntawm lub vas me dhau, nws yuav ua rau daim zaj duab xis tev tawm. Yog tias muaj kua mem ntau dhau nyob hauv lub mesh, cov ntawv luam tawm yuav qias neeg.

Qhov teeb meem no daws tau los ntawm kev nce qhov deb ntawm lub vijtsam thiab lub substrate. Txawm li cas los xij, kev nce qhov deb ntawm lub vijtsam thiab lub substrate yuav tsum tau nce qhov siab, uas yuav ua rau muaj ntau tus number case hloov mus rau lub substrate. kom hloov qhov ceev ntawm cov xim. Txoj hauv kev zoo tshaj plaws yog kom khaws qhov nruj ntawm lub net ncab sib npaug, kom ntseeg tau tias cov xim sib xws.

 

04 Qib siab
Kev teeb tsa lub zog kom raug yog qhov tseem ceeb rau kev tswj cov xim kom sib xws, thiab kev ua kom muaj lub zog sib npaug thaum lub sijhawm luam ntawv yog qhov tseem ceeb heev. Tshwj xeeb tshaj yog nyob rau hauv cov haujlwm luam ntawv ntau thiab rov ua dua.

Thaum nws los txog rau qhov siab, thawj qhov yuav tsum xav txog yog qhov nyuaj ntawm lub squeegee. Qhov nyuaj ntawm lub squeegee yog me me, uas yog qhov zoo rau qhov nrawm ntawm kev sib cuag, tab sis nws tsis zoo rau kev tiv thaiv khoov. Yog tias qhov nyuaj siab dhau, qhov sib txhuam ntawm lub vijtsam kuj yuav loj thaum lub sijhawm luam ntawv, yog li cuam tshuam rau qhov tseeb ntawm kev luam ntawv. Qhov thib ob yog lub kaum sab xis ntawm lub squeegee thiab qhov ceev ntawm squeegee. Lub kaum sab xis ntawm rab riam kua muaj qhov cuam tshuam loj rau qhov ntau ntawm kev hloov pauv kua. Lub kaum sab xis ntawm rab riam kua me dua, qhov ntau ntawm kev hloov pauv kua. Yog tias qhov ceev ntawm rab riam kua ceev dhau, nws yuav ua rau tsis txaus kua thiab tsis tiav kev luam ntawv, yog li cuam tshuam rau qhov zoo ntawm kev luam ntawv.

Thaum koj tau txais qhov chaw teeb tsa siab kom raug rau txoj haujlwm luam ntawv thiab sau cia kom raug, tsuav yog koj ua raws li cov chaw teeb tsa no kom raug thaum lub sijhawm luam ntawv, koj yuav tau txais cov khoom luam ntawv zoo nrog cov xim sib xws.

 

05 qhuav
Qee zaum, cov xim zoo li sib xws tom qab luam ntawv, tab sis cov xim hloov pauv tom qab pom cov khoom tiav lawm. Qhov no feem ntau yog los ntawm kev teeb tsa tsis raug ntawm cov khoom siv ziab. Qhov ua rau feem ntau yog qhov kub ntawm lub tshuab ziab khaub ncaws tau teeb tsa siab dhau, ua rau cov xim kua mem ntawm daim ntawv lossis daim ntawv cardboard hloov pauv.

 

06 Cov yam ntxwv ntawm cov khoom siv
Ib qho teeb meem uas cov kws luam ntawv feem ntau tsis quav ntsej yog qhov zoo ntawm cov khoom siv hauv pem teb. Daim ntawv, daim ntawv cardboard, yas, thiab lwm yam yog tsim tawm ua pawg, thiab cov khoom siv zoo tuaj yeem ua kom cov khoom siv hauv pem teb ruaj khov thiab sib xws. Tab sis qhov no tsis yog qhov tseeb. Kev hloov me me ntawm cov khoom siv hauv pem teb yuav ua rau muaj kev hloov pauv xim hauv kev luam ntawv. Txawm tias lub zog luam ntawv zoo ib yam thiab txawm tias txhua txoj kev ua haujlwm raug, qhov tsis sib xws ntawm cov khoom siv hauv pem teb kuj tseem yuav ua rau muaj kev hloov pauv xim loj dua hauv kev luam ntawv. Xim ploj.

Thaum cov khoom tib yam raug luam tawm rau ntawm cov khoom sib txawv nrog cov cuab yeej luam ntawv tib yam, qhov cuam tshuam ntawm cov khoom nto ntawm cov khoom siv rau ntawm cov xim yog qhov pom tseeb tshwj xeeb. Cov neeg siv khoom yuav xav tau cov ntawv tshaj tawm qhov rai kom luam tawm rau ntawm yas lossis lwm yam ntawv cardboard. Thiab cov neeg siv khoom yuav xav tau cov xim sib xws rau tib daim.

Hauv cov xwm txheej zoo li no, tib txoj kev daws teeb meem yog ua kom raug qhov ntsuas xim. Siv lub spectrophotometer lossis spectral densitometer los ntsuas qhov ceev ntawm xim. Yog tias muaj kev hloov xim, lub densitometer tuaj yeem cuam tshuam nws kom meej meej, thiab koj tuaj yeem kov yeej qhov kev hloov xim no los ntawm kev tswj hwm lwm cov txheej txheem.

 

07 Cov xwm txheej soj ntsuam

Tib neeg lub qhov muag rhiab heev rau qhov kev hloov pauv me me ntawm cov xim, thiab tsuas yog tuaj yeem paub qhov txawv ntawm cov xim hauv qab lub teeb pom kev zoo. Vim li no, nco ntsoov sib piv cov xim hauv qab tib lub teeb pom kev zoo. Txwv tsis pub, kev kho qhov ntim ntawm cov kua mem lossis lub zog yuav tsim cov kua mem ntau dua. Cov xim loj.

Tag nrho hauv txhua yam, qhov tseem ceeb rau kev tswj cov xim sib xws yog nyob rau hauv kev tswj hwm ruaj khov ntawm txhua txoj kev kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov kua mem. Kev xaiv ntawm qhov loj me me, kev nruj thiab siab ntawm lub vijtsam ncab, cov yam ntxwv ntawm qhov chaw ntawm lub substrate thiab cov xwm txheej soj ntsuam txhua yam muaj qee qhov cuam tshuam rau kev hloov pauv xim. Txawm li cas los xij, cov ntaub ntawv teeb tsa raug thiab kev tswj hwm ruaj khov ntawm txhua txoj kev yog qhov tseem ceeb rau kev ua kom cov xim luam ntawv sib xws.
