Overprint kev hloov pauv feem ntau ua rau muaj teeb meem ntau rau kev luam ntawv, uas cuam tshuam rau kev ua haujlwm luam ntawv. Ntawm no yog peb qhov laj thawj yog vim li cas qhov teeb meem ntawm overprint hloov pauv tuaj yeem ua. Tshwj xeeb xav tau yog qhov xav tau thaum lub sijhawm khoom.
1. Txhim kho teeb meem tshwm sim los ntawm hluav taws xob tsis zoo
Feem ntau, hluav taws xob feem ntawm cov lej sau npe cov gravure sau npe cov ntu suav nrog cov feem sib nkag siab, ib txheej txheem ua, thiab tus ntsuas. Txhua ntu ntawm kev ua haujlwm tsis yog li qub, nws yuav ua rau overprint hloov pauv. Yog li, txhawm rau txhawm rau txheeb xyuas cov laj thawj ntawm kev hloov pauv kev hloov pauv, nws yog ib qho tsim nyog yuav tsum paub txog cov qauv hluav taws xob ntawm kev tiv thaiv overprint.
Cia peb muab cov kab sib tsoo ua kab ua piv txwv los txhawm rau txhawm rau txheeb xyuas hluav taws xob hauv kev ua haujlwm ntawm kev hla kev.
Hauv txhua qhov xim luam tawm, txhua qhov hloov kho ntawm phaj lub tog raj kheej tsim tawm cov mem tes uas nkag rau ntawm lub rooj tsavxwm nrog rau 500 pulses tsim los ntawm qhov ntsuas ntawm lub tshuab luam ntawv. Tom qab ua tiav los ntawm pawg tswj hwm encoding, plaub lub mem tes yog tsim thiab xa mus rau cov chaw ntsug (lossis tom qab) sau npe tswj hwm. Ntawm no, lub teeb liab plaub lub plawv yog piv nrog ib lub teeb liab mem tes tau los ntawm kev kuaj pom tus cursor ntawm cov ntawv luam tawm. Yog hais tias overprinting sib txawv tshwm sim nyob rau lub sijhawm no, lub npe Circuit board board tawm qhov voltage ntawm txog 5 volts rau hauv PLC. Tom qab ua tiav los ntawm PLC, stepper tsav tsav tau tsav lub zog tsav lub kauj hluav taws xob kom ua tiav lub hom phiaj ntawm kev cuv npe hloov kho.
Tshawb xyuas overprint kev hloov pauv los ntawm cov teeb meem hluav taws xob feem ntau yog txoj hauv kev kom saib. Raws li kev nkag siab lub hauv paus ntsiab lus hluav taws xob ntawm txheej txheej txheej txheej txheej dhau kev tswj hwm, xyuas seb cov hluav taws xob sib thooj puas zoo li qub thiab daim hluav taws xob puas hloov. Txawm li cas los xij, tom qab muaj kev paub ntau heev hauv kev kho cov ntawv sau npe ntawm hom kev nqus luam ntawv tshuab, nws kuj tseem tuaj yeem yoog txoj kev xav dhia, kom cov kis ntawm qhov tsis tuaj yeem nrhiav tau sai dua.
2. Tshaj dhau kev hloov pauv tshwm sim los ntawm kev siv tshuab tsis ua haujlwm
Los ntawm cov kev paub dhau los, tsis muaj ib qho kev hloov pauv rau kev ntsuam xyuas ntawm qhov teeb meem kho tshuab ntawm kev sib tshooj. Tsuas yog tom qab kev nkag siab thiab dhau tus txheej txheem ntawm cov tshuab ntawm cov xovxwm sib tsoo, nws paub tias yam twg tus qauv lub tshuab yuav cuam tshuam rau qhov kev ua kom dhau, thiab dhau los ntawm kev sib tw yuav pom qhov tshwm sim sai li sai tau. Yog lawm, txij li "cov tsos" ntawm cov neeg kho tshuab tsis ua hauj lwm feem ntau yog hais ntau tshaj li qhov "pom tau" ntawm cov hluav taws xob yuam kev, nws yog qhov yooj yim kom pom qhov tshwm sim hla kev hloov mus los.
Piv txwv li, tom qab siv lub sijhawm ntev ntawm lub tog raj kheej pom, lub nplaim yuav pom tseeb cim hnav, uas yuav cuam tshuam rau lub ntsej muag over precision. Qhov thinner lub substrate, ntau dua qhov cuam tshuam rau overprint raug. Tsis tas li ntawd, yog tias nws pom tias qhov kev tshaj tawm lub tog raj kheej vibrates nce thiab nqis thaum lub sijhawm luam ntawv, nws zoo li qhov kev pom zoo lub tog raj kheej cov khoom siv yog puas lawm, uas muaj kev cuam tshuam rau kev ua npe ntev ntawm cov ntawv luam tawm.
Rau lwm qhov piv txwv, yog tias lub phaj lub tog raj kheej tsis raug kaw, yuav muaj kev sib tw me ntsis, uas feem ntau ua rau kev cia li dhia hauv cov ntawv tom ntej. Ntxiv rau, daim ntawv qhia cov menyuam tau txais kev hloov kho tom qab, thiab cov teeb meem tshwm sim hauv qhov kis ntawm cov kauj ruam lub cev muaj zog, uas tseem ua rau kev hloov dhau ntawm qhov hloov. Ntxiv mus, hom overprinting tsis ua haujlwm, nws qhov kev ua tau zoo yog qhov loj, cia li hla kev dhia dhau ib lub sijhawm hauv cov txheej txheem ntau lawm.
3. Overprint hloov pauv kev cuam tshuam los ntawm lwm yam
Ntxiv nrog rau kev siv hluav taws xob thiab kev siv tshuab, kev hloov dhau qhov tshwm sim los ntawm lwm qhov tsis tuaj yeem tsis quav ntsej.
Ua ntej, kev saib xyuas tsis raug tuaj yeem ua rau overprint hloov mus. Piv txwv li, yog tias qhov nro tsis raug teeb tsa kom zoo, daim ntawv yuav xoob thiab nruj thaum lub sijhawm ua haujlwm siab, uas yuav cuam tshuam rau cov ntawv sau npe ntsug. Rau lwm qhov piv txwv, yog tias qhov cub ntsuas kub dhau heev, nws yuav ua rau daim ntawv deform ntau dhau tom qab dhau los ntawm qhov cub, uas yuav cuam tshuam rau kev ua haujlwm dhau ntawm cov xim tom ntej.
Thib ob, cov khoom siv raw thiab cov chaw ib puag ncig kuj tseem muaj qhov cuam tshuam los ntawm kev ua tiav. Yog tias daim ntawv dhau xoob, qhov kev ntxhov siab tiag tiag yuav hloov ntau zaus, thiab kev ua haujlwm nyuaj yuav tau nce ntxiv. Cov ntawv tshaj tawm tsis tso cai rau feem ntau nyob rau hauv kev coj ua ntev; qhov tsis sib xyaw ntawm daim ntawv ntug yuav ua rau daim ntawv qhia kev ua kom tsis txhob txav thiab cuam tshuam rau kev tawm tsam tom qab. Qhov ntsuas kub thiab vaum ntawm thaj chaw tsim khoom yuav muaj qhov cuam tshuam rau qhov kev txiav tawm ntawm daim ntawv thaum lub sijhawm luam ntawv.
