Overprinting tsis yog ib qho teeb meem kev nyuaj hauv kev luam ntawv. Nws muaj plaub qhov phenomena thiab peb yam tseem ceeb. Plaub hom phenomena, namely, luam tawm overprinting tsis yog lawm, feem luam ntawm daim ntawv luam tawm tsis pub, tsis tshaj qhov tsis pub, thiab cov ntawv luam rov qab tsis raug tso cai. Qhov peb yam tseem ceeb tshaj plaws yog luam tawm ntawm phaj ua, kos duab, ua yeeb yam, thiab ua luam ntau dhau los ntawm kev ncab ntawv. Tsis muaj kev cuam tshuam los ntawm kev ua tsis zoo ntawm lub tshuab luam ntawv tshuab luam ntawv los yog kev ua haujlwm tsis zoo thiab kev hloov. Tsis tau tshaj qhov tsis pub kom muab faib ua ob hom: ntsug overprinting thiab horizontal overprinting. Cov nram qab no yog cov ntsiab lus ntawm ntau tshaj ntawm cov kev ua txhaum ntau dhau los nrog kev ua haujlwm kom ntau, thiab tawm tswv yim daws teeb meem.
Tsis pub siv ntsug overprinting
1. Kev txhim kho los ntawm kev ua tsis tiav ntawm daim ntawv
Kev tsis txaus sau tus kheej tsis tshaj yog txhais tau hais tias qhov chaw ntsiag to ntawm unilateral crosshairs tsis yog overprinted, thiab lub overprinted crosshairs yog nyob rau hauv cov kev taw qhia ntawm tus qauv kab. Muaj 7 hom tshuaj ntsuam xyuas thiab kev daws teeb meem.
(1) Lub sij hawm thaum kev sib sib zog nqog ua rau sab yog thaum ntxov dhau
Thaum daim ntawv uas tau nquag thauj tsis tau mus txog rau hauv ntej ntsuas, lub sab gauge rub tawm ntawv pob thaum ntxov dhau los tso thiab nias ntawv, kom daim ntawv tsis nyob rau hauv qhov chaw, ua rau tsis muaj tseeb tshaj tawm.
Tshuaj: Lub sijhawm zoo ntawm lub sab xaib yuav tsum yog tom qab daim ntawv nquag xa mus rau pem hauv ntej ntsuas cua; lub sij hawm tuaj tos yuav tsum yog thaum daim ntawv swayed los ntawm daim ntawv swb, uas yog, lub viav vias thiab kaw qhov muag hlau tawm hauv cov xim. Ob txoj kev ntswj hauv qhov ntsuas ntawm lub sab cua siv lub lauj kaub ces yuav loos kom tig rov qab rau hauv khej kom txog thaum lub sij hawm poob ntawm qhov saum toj no thiab kev sib zog ua kom tiav.
(2) Lub hauv paus lus gauge lus tsis txaus
Thaum daim ntawv npog tam sim no tsawg tshaj 3 zaug ntawm cov ntawv pov thawj, daim ntawv yuav raug thaiv thiab tsis tawm mus.
Tshuaj: Xoos tus ntsia hlau ntsia sab nrauv hauv ntej, nqa pem hauv ntej koob npe, ntxig 3 nplooj ntawv ntawm daim ntawv tuav, thiab ceev cov ntsuas kev sib zog. Lub tshuab tsis pub nres ntawm qhov chaw uas lub hauv ntej qhov ntsuas cua ntog rau ob peb lub lis piam, thiab tom qab ntawd peb nplooj ntawv yuav muab tso rau hauv daim ntawv tuav kom rov txiav txim dua, kom peb nplooj ntawv sau tau thiab tawm tau dawb, thiab plaub nplooj ntawv tsis tuaj yeem muab tso .
(3) Daim ntawv tso sijhawm yog lig dhau lawm
Qee lub sij hawm daim ntawv tuaj yeem dhau los ua ntej daim ntawv tuaj txog. Tshwj xeeb tshaj yog thaum lub sab gauges yog nias ntawm sab gauges, lawv yuav tsis tau advanced. Lwm sab ntxiv mus rau pem hauv ntej koob ntsuas pa, uas yuav ua rau ib leeg tsis ua haujlwm.
Tshuaj: Txhob muab txoj hlua khi ua kom zoo dua, muab daim ntawv tso rau hauv daim ntawv tso rau hauv cov ntawv ceev ceev, thiab rub lub ntsaws rov qab. Tom qab lub hauv ntej rau hauv qhov chaw, qhov ntug ntawm daim ntawv yuav tsum yog 6-8 hli ntawm qhov ntawv nres.
(4) Lub sab xaib sab nraud pov tseg kom dhau qeeb
Yog vim li cas thiaj yog: thaum daim ntawv swaying thiab daim ntawv pib txav mus rau pem hauv ntej, daim ntawv tseem tab tom ntaus tawm ntawm daim ntawv, thiab daim ntawv rho tawm ntawm daim ntawv swaying, thiab lub luam ntawm cov khoom luam tawm thiab ib sab tsis pub. Qhov tshwm sim yog tib yam.
Kev Tua: Qhov ntsuas tawm sab nraud rub lub pob thiab nqa nws qeeb qeeb, qhia tias qhov chaw ua hauj lwm ntawm lub rooj ua haujlwm tsis hloov kho. Lub sij hawm no, ob qhov kev sib tsoo ntawm qhov ntsuas lub koob yees duab yuav raug loosened, tom qab ntawd cov xim khij nyhia dua, thiab lub hau ntswj nruj dua thiab mam rov kuaj dua kom ncav raws li txoj cai.
(5) Lub taub hau yog lub teeb heev
Cov hlua khi ntawm daim ntawv npog cov ntaub ntawv thiab cov neeg ua khoom pauj nplaum yog lub teeb heev, cov neeg sau khoom tsawg dhau los, los yog cov quab yuam kom qis tsis zoo. Nws kuj yog ib qho yooj yim uas yuav ua rau qhov kev tshaj tawm tsis muaj tseeb, uas yog nyob rau hauv tib lub phenomenon uas luam tsis yog tsis muaj tseeb.
Tshuaj: Yog tias nws yog qhov teeb meem ntawm lub caij nplooj ntoos hlav los yog lub caij nplooj ntoos hlav, nws yuav tsum tau hloov; Yog hais tias tus hniav ntawm daim ntawv swb ntawv tsis txaus thiab tsis sib txig, nws yuav tsum tau hloov. Tom qab siv lub tshuab luam ntawv, lub tshuab luam ntawv yuav ua tau rau cov kev sib tshuam ntawm lub tswv yim kheej thiab lub oscillating gripper nrog tag nrho cov kev hloov kho, thiab qhov swinging ncoo yog 0.3 hli ntawm lub dav hlau ntawm lub tswv yim kheej hws. Thaum kho tag nrho, koj tuaj yeem ploj tag nrho hlau phaj ntawm tus hniav txhuam hniav, kho lub txiv ntoo rau ntawm lub viav vias, tig lub koob poom kom txog clockwise, thiab tig tus pos hniav kom ncav mus txog thaum nws nce mus txog 0. 3 hli. Raws li ntawv me me, nws yog ib qho tsim nyog los xyuas kom meej tias daim ntawv swayed thiab embossed, thiab crepe ntawv yog 5 thiab 6 hli.
(6) Lub ntsis ntawm lub tsheb laij teb poob lawm.
Qhov me me ntawm txoj kev txhuam tsuas yog los tiv thaiv daim ntawv los ntawm kev nkag mus rau hauv ntej kev sib tsoo thiab ces tawm mus. Tej zaum nws yuav muaj li nram qab no: 1 Thaum daim ntawv noj mov raug tso tseg vim yog xaws ntawm daim ntawv pub, kom tshem tawm daim ntawv rau ntawm cov ntawv xov xwm, tus ncej muab rov qab thiab qhov txiav txim yog dhau hnyav, ua rau txhuam muab tsa los yog cuam tshuam. 2 Txhuam txhuam hauv ib txoj haujlwm ntev. Yog hais tias nws siv ntev, qhov uas qhov txhuam rub tawm tsam ntug ntawm daim ntawv tau ua txhaum thiab poob nws cov nyhuv. 3 Txoj hauj lwm uas txhuam cov ntawv txhuam hniav yog tsis muaj tseeb. Daim ntawv no nyob rau ntawm qhov txhuam ntawm txhuam los yog hauv paus.
Tshuaj: Qhov teeb meem thib ib thiab thib peb yuav tsum tau rov kho dua tshiab; qhov teeb meem thib ob yog tshem tawm cov txhuam thiab hlawv nws ntawm qhov hluav taws kub. Cov txheej txheem yog raws li nram no: thawj zaug, ib qho me me ntawm cov hlau phaj yog kub hnyiab hauv qhov hluav taws kub, thiab mam li rov qab rau hauv av tom qab muab pov tseg, thiab tom qab ntawd ces txhuam nrawm nrawm rau xim liab hlau raws li qhov xub thawj siab . Nws yog qhov yooj yim kom tau flattened. Yog tias nws hnav lawm, nws tuaj yeem kub hnyav tau ntau zaus kom txog thaum nws tseem tiaj tus (thov ceeb toom tias qhov txhuam no yuav tsis raug txiav).
(7) Lub txhuam lub log yog lub teeb heev lossis ob lub thawv ntawv platen ntawm lub hau ntawm lub hau tsis dais tawm tsam ntawm daim ntawv tom qab. Qhov txhuam txhuam thiab cov hlua ntawm 2 daim ntawm tus ntaiv ntawm lub tsheb laij npav kom paub meej thiab ruaj khov ntawm daim ntawv thaum nws nkag mus rau pem hauv ntej koob qhia. Lawv lub siab nyob rau hauv daim ntawv yuav tsum tsis txhob hnyav dhau los yog dhau ntawm lub teeb, hnyav dhau los ua rau sab nraum qab yuav qias neeg; dhau lub teeb ntawm daim ntawv kom poob nws txoj kev ua kom zoo, yooj yim kom daim ntawv tawm ntawm qhov chaw. Qee lub sij hawm 2 ntawm txhuam log los yog 2 platen log, ib lub siab yog qhov tsim nyog, lub siab yog qhov kaj, thiab qhov kaj yuav ua rau ib sab tawm ntawm qhov chaw.
Kev Tov: Ob txoj kab choj uas ua si tseem ceeb hauv kev tshaj tawm thiab ob daim ntawv npog ntawm lub hau yuav khaws cia rau tib lub siab, thiab lawv yuav tsum nyob rau hauv qhov chaw, uas yog, txhuam txhuam yuav tsum tau muab nias rau ntawm daim ntawv saum daim ntawv pub mis nyuj; Ob daim ntawv npog ntawm qhov taub ntawm lub tsheb laij teb yuav tsum kaw ntom ntsa rau ntawm daim ntawv tom qab.
