Lub overprinting tseeb ntawm letterpress prints yog ib qho ntawm cov tseem ceeb tshaj plaws los mus ntsuas qhov zoo ntawm embossed cov khoom. Txawm li cas los xij, vim kev ua haujlwm tsis zoo thiab kev ua haujlwm, muaj ntau yam kev ua yuam kev xws li tsis ruaj nrees thiab tsis tuaj yeem ua haujlwm hauv kev luam ntawv, uas tsim kev puas tsuaj thiab yuav tsum tau ua tiag. Muaj ntau ntau yam rau cov ntaub ntawv tsis muaj tseeb ntawm cov khoom siv kabmob:
1. Kho kom zoo dua kev hloov kho, siab tus number case siab viscosity, tsis ruaj tsis khov ntawm daim ntawv teev lus sau rau hauv ntej koob qhia
Kev xyaum tau pom tau tias ua kom muaj tus cwjpwm zoo ntawm tus cwjpwm zoo yog qhov tseemceeb uas yuav tsum ua kom zoo rau cov khoom luam tawm. Tus cwj mem tsis muaj ib qho viscosity tsis tuaj yeem muab luam tawm nrog ib tus lej txheej uas yog xim dawb, tag nrho thiab kaj. Txawm li cas los xij, nws tsis muaj cov qauv zoo rau tus number case viscosity, thiab cov viscosity ntawm tus cwj pwm muaj peev xwm hloov kho tau raws li cov yam ntxwv ntawm cov ntawv luam tawm (substrate) thiab cov qauv ntawm lub phaj luam ntawv. Yog hais tias qhov ua rau lub cev tsis muaj zog, cov roj hmab yuav rub tawm, uas ua rau tsis muab hloov mus rau lwm tus, thiab "oily" cov duab yuav tshwm tuaj rau ntawm daim ntawv luam tawm. Yog hais tias tus cwj mem ntawm tus cwj mem xiav yog loj heev, daim ntawv luam tawm hauv lub pob ntseg yog yooj yim rho tawm ntawm tus cwj pwm thiab cov ntawv ntub nrog lub nruas, ua qhov tsis zoo uas qhov chaw uas tsis yog qhov tseeb tsis muaj tseeb. Piv txwv li, thaum lub DT4OO plaub-qhib lub cav tsis zoo siv lub tshuab luam tawm, yog tias tus number case no tseem khov heev, nws yuav muaj lub zog nrawm ntawm cov ntawv luam ntawm lub nruas, kom cov ntawv txheeb tawm los ntawm cov hniav, rau pem hauv ntej ntsuas cua Qhov yuam kev muaj peev xwm ncav cuag txog 3 lub hli, thiab qhov tsim teeb meem loj heev. Yuav kom tsis txhob muaj qhov tsis ua hauj lwm, thaum luam ntawv tawm tsab ntawv nrog rau ntau tus number case absorption, raws li tus viscosity ntawm tus cwj pwm, tus nqi tsim nyog ntawm cov khoom ntim lossis cov kua roj voos yuav ntxiv rau qhov tsim nyog kom txo tau qhov adhesion ntawm tus cwj pwm daim ntawv luam kom paub meej tias luam ntawv ua tiav. .
2, kev hloov ntawm kev luam ntawv, qhov cuam tshuam rau kev luam ntawv zoo
Kev luam tawm yog ib qho tseem ceeb hauv kev ua tiav cov ntawv hloov ntawm cov ntawv sau. Lub tshuab luam tawm ntawm cov lauj kaub uas zoo tshaj plaws yog muab tau los ntawm kev siv lub tshuab luam ntawv kom mob siab. Nyob rau hauv dav dav, thaum lub npoo ntawm lub substrate yog ntxhib thiab luam tawm qhov loj loj, lub printing siab yuav tsum tau nce raws li. Txawm li cas los xij, hauv kev ua haujlwm, lub tshuab luam ntawv tsis tuaj yeem ua qhov muag tsis pom ntxiv kom los siav tau qhov kev tawm ntawm cov ntawv luam tawm ntawm cov lej. Lub tshuab luam ntawv yog ib yam nkaus thiab hnyav heev, uas tsis yog tsuj lub tsho ntawm lub tshuab thiab cov ntawv xov xwm, tab sis kuj yooj yim ua rau kev ua yuam kev. Qhov no yog vim thaum lub tshuab luam ntawv loj loj heev, ntawm ib sab tes, daim ntawv luam yuav muab deformed, ua rau cov ntawv xov xwm tuaj yeem ua kom loj dua, ua qhov tsis zoo lawm; ntawm qhov tod tes, lub tshuab luam ntawv loj heev, thiab luam tawm ntawm lub plhaub tiab yuav raug tsim txom thaum uas luam tawm. Cov quab yuam ua rau daim ntawv luam tawm kom qis tawm sab nraud, uas yuav ua rau txoj haujlwm tsis muaj zog thiab tsis tuaj yeem pom me me. Yuav kom tsis txhob muaj kev phom sij, qhov kev hloov siab ntawm cov ntawv luam ntawv yuav tsum maj mam thiab maj mam nias nyob rau hauv rooj plaub uas muaj tus cwj pwm nkag mus rau qhov tsim qhov qub, yog li ntawd lub tshuab luam ntawv tsim nyog yuav tsum tau kho kom meej meej rau cov ntawv luam zoo.
3, daim ntawv phom hauv qab tsis yog khoom, qhov tsis txaus thiab qhov sib txawv ntawm qhov sib txawv ua rau luam tsis raug.
Lub zog thiab ua kom tiav ntawm lub phaj kev txhawb nqa (daim nplaum hauv qab) siv rau kev luam ntawv luam loj heev cuam tshuam cov kev luam ntawm qhov khoom. Yog hais tias cov khoom siv tshuaj ua ke yog siv cov phaj rau cov ntawv loj loj rau cov ntawv luam ntawv, cov lus sib txuas lus yooj yim yog vim cov pluag tsis haum, kev ceev thiab kev ywj pheej ntawm cov plywood. Nyob rau hauv cov txheej txheem luam ntawv, nws yog ua txhua yam tsis ncaj vim tias tsis ncaj los sis hauv qab. Loj loj printing, uas yog yooj yim ua rau distortion ntawm luam tawm nto, ua cov ntawv loj loj tshaj qhov tseeb version. Tsis tas li ntawd, txij li cov ntoo hauv qab yoojyim yoojyim, tus luam tawm ntawm tus kheej kheej nyob rau hauv lub embossing yuav inevitably ua slippage vim me ntsis kev co los yog lub zog ntawm cov ntawv phaj, uas ua rau cov ntaub ntawv ntawm qhov khoom. Yog li ntawd, nyob rau hauv lub phaj printing nrog loj printing dav thiab siab, nws yog zoo dua los siv ib lub phiab hlau los yog ib qho phaj txhuas los xyuas kom meej ntawm cov khoom ntawm overprinting.
4, qhov khoos phis hauv kev lag luam zoo los tiv thaiv kev rhuav tshem ntawm cov khoom luam tawm los ntawm kev tshaj saud
Lub khauj yog ib tug choj kom paub txog kev hloov ntawm qhov kev teeb tsa, uas muaj qee yam cawv rau ntawm kev luam ntau. Vim muaj qhov sib txawv hauv cov qauv ntawm cov khoom, qhov uas yuav tsum tau ua rau tuab ntawm lub qhov quav kuj yog txawv. Tsuas yog los ntawm kev tswj ntawm qhov meem ntawm lub tshuab hauv lub tshuab raws li cov specifications ntawm lub tshuab luam ntawv tuaj yeem luam tawm qhov tsim tawm. Yog hais tias lub thickness ntawm sab hauv yog tsis txaus, qhov ntev ntawm qhov ntev ntawm daim ntawv sau tawm yog feem ntau me me tshaj qhov sib npaug ua luam phaj ntev; Yog hais tias lub thickness ntawm lub meem ntau tshaj qhov teev tsis ntawm cov khoom siv, cov ntawv sau tawm loj tshaj qhov tseeb cov luam tawm nto, uas yog lwm yam cuam tshuam txog qhov kev luam ntawm kev luam.
Tsis tas li, yog tias lub pob khawm pob tsis nruj txaus, muaj qhov tshwm sim xws li looseness, qij, thiab qhov loj hauv thaj tsam ntawm sab hauv sab, los yog tsuas yog sab ntawm lub plob qhov nip yog muab tso rau ntawm daim ntawv padding, thiab ib qho piv txwv ntawm txoj haujlwm tsis sib haum yog tsis muab, cia nws ntab Qhov no tseem ua rau cov ntawv xov xwm ua kom zoo heev, ua rau luam ntawv misalignment. Yuav kom paub tseeb tias qhov tseeb ntawm cov ntawv luam ntawv, nws nyiam siv cov khoom nruab nrab thiab tsis sib haum, thiab muab cov khoom ntim rau kom nruj.
5. Cov npuaj ntawm qhov muag ntawm cov quav yuav ua rau daim ntawv sau ua tsis raug.
Thaum muab cov ntaub ntawv luam tawm, yog tias lub siab ntawm tus menyuam tsis muaj txhij txhua, daim ntawv luam tawm hauv lub pob ntseg tau yooj yim tawm sab nraud los ntawm cov hniav ntawm cov hniav vim tias qhov kev hloov siab tawv tuaj ntawm cov ntawv luam tawm. Piv txwv li, lub DT400 plaub-qhib automatic platform tshuab luam ntawv yog nws cov teeb meem saum toj no-hais tawm thaum luam ntawv thaj tsam loj ntawm tsab ntawv sau khoom. Lub ntsiab tseem ceeb rau kev tshawb fawb yog tias qhov siab ntawm lub caij nplooj ntoos hlav steel piece ntawm thawj lub tshuab nruas yog tsis txaus, yog li hais tias kev tom tsis tom cov ntawv ntug. Tus neeg sau ntawv tau ntxiv cov ntawv txheeb steel los mus rau lub nruas hniav kom tiav cov qaug dab peg ntawm cov ntawv txheeb, tiv thaiv cov ntawv txheeb los ntawm kev ntog tawm thiab tsiv thaum ua dab ntxwg nyoog, thiab cov ntaub ntawv luam yog zoo dua. Tsis tas li ntawd, lub tshuab muaj lwm qhov teeb meem uas cuam tshuam qhov kev teeb tsa ntawm daim ntawv, uas tsim nyog. Ntawd yog, tom qab luam ntawv nkag rau lub nruas los tom cov hniav, muaj ib lub thauv me me tom kawg ntawm daim ntawv luam thaum lub sijhawm kaw cov neeg sau khoom, uas ua rau muaj kev tshwm sim luam tawm. Lub ntsiab yog vim li cas tus lej no los yog cov ntawv uas muaj agglomerated ntawm cov hmoov av tuaj yeem nyob rau hauv cov hniav coj mus rau sab sab. Thaum cov hniav raug kaw, cov plua plav lawm hauv cov hniav tsuas hits ntug ntawm daim ntawv, ua rau txoj hauj lwm pem hauv ntej kom tsis raug. Ntev npaum li cov plua tshauv hauv cov hniav ntxuav, qhov txhaum yuav raug tshem tawm.
Nyob rau hauv cov ntsiab lus, qhov zoo ntawm kev lag luam thiab cov txheej txheem siv tshuab tsis zoo tsuas lav tau qhov kev luam ntawv zoo ntawm daim ntawv luam ntawv, zoo dua cov luam ntawm cov khoom luam tawm, tab sis tseem ua tau zoo ntawm cov khoom lag luam.
