Cov yam ntxwv cuam tshuam rau cov xim tsis sib xws ntawm cov khoom:
1. Lub thickness tsis sib npaug ntawm cov number case txheej tshwm sim los ntawm kev luam ntawv bar cim. Lub thiaj li hu ua luam ntawv "bar mark", tseem hu ua "rov qab kua nplaum duab ntxoov ntxoo", feem ntau hu ua "rubber roll mark". Nws kuj yog ib qho kev tsis txaus ntseeg hauv cov txheej txheem ntawm cov ntawv luam ntawv, uas yog, muaj ib lossis ntau daim kab txaij duab ntxoov ntxoo nrog pom tseeb qhov sib txawv ntawm cov xim ntxoov ntxoo nyob rau hauv txoj hauj lwm kab rov tav ntawm cov khoom luam tawm, uas cuam tshuam rau kev zoo nkauj ntawm cov khoom. . Muaj ntau yam laj thawj rau cov ntawv luam ntawv bar, suav nrog cov laj thawj kev ua haujlwm thiab cov txheej txheem thev naus laus zis. Xws li cov ntaub ntawv tsis sib xws lossis siab dhau lawm, kev luam ntawv siab hnyav dhau lawm, cov tshuab luam ntawv yog ib qho nyuaj thiab yooj yim rau plam lossis nws qhov siab tsis hloov kho zoo, cov inking roller tsis txaus, tus number case tsis txaus, lossis cov roj hmab yob headwear gap yog qhov chaw luam ntawv bar cim. Tsis tas li ntawd, yam xws li tus cwj mem xim, tus cwj mem ntxoov ntxoo sib txawv, thiab kev hloov kho tsis zoo ntawm tus number case viscosity kuj yog ib qho laj thawj rau kev luam ntawv bar. Yog li ntawd, txhua yam ntawm cov tshuab luam ntawv yuav tsum tau ua kom zoo los tiv thaiv kev luam ntawv ntawm cov xim tsis sib xws.
2. Qhov tsis muaj tus lej ntawm tus number case hauv koob ua rau cov xim tsis sib xws ntawm tus number case strip. Qhov sib txawv ntawm lub thickness ntawm tus number case txheej tshwm sim los ntawm longitudinal txoj hauj lwm ntawm lub luam ntawv kuj yog ib qho teeb meem tshwm sim nyob rau hauv phaj printing. Qhov no yog vim muaj qhov tsis xws luag hauv cov qauv ntawm tus number case hopper, nws tsis tuaj yeem hloov kho mus rau qhov tseeb longitudinal number case xa uniformity, vim li no, muaj ntau pab pawg hlau rollers uas ua lub luag haujlwm ntawm tus number case, thiab qhov loj ntawm txoj hlua. stroke tuaj yeem hloov kho ntawm qhov xav tau, thaum luam ntawv cov khoom lag luam nrog ntau tus number case, txoj hlua ntawm cov hlau rau cov menyuam yuav tsum tau hloov kho kom ntseeg tau tias cov khoom sib txawv ntawm tus number case.
3. Qhov chaw luam ntawv loj dhau lawm, thiab cov qauv thiab kev ua haujlwm ntawm cov khoom siv tsis haum rau cov xim tsis sib xws. Qhov loj ntawm cov ntawv luam tawm, qhov muaj zog dua qhov adhesion ntawm tus number case txheej thiab cov phaj luam ntawv, yog li thaum embossed, vim qhov tsis sib xws ntawm qhov adhesion ntawm tus number case thiab daim ntawv luam ntawv thiab lub zog adsorption ntawm daim ntawv ntawm tus number case, nws yog inevitable yuav tsum tau ua nyob rau hauv lub zos, yog li ntawd lub number case txheej yog tawg, thiab yog li ntawd tsis tuaj yeem yuav uniformly thiab tag nrho hloov mus rau daim ntawv. Yog li ntawd, txhawm rau luam cov khoom lag luam loj hauv cheeb tsam, nws yog qhov tsim nyog los siv lub tshuab hluav taws xob teb nrog lub voj voog flattening qauv los yog cov xovxwm rotary nrog lub voj voog xovxwm, kom cov xim number case luam ntawv zoo ib yam.
4. Tsis sib npaug luam ntawv siab lossis phaj txhawb tsis muaj zog, yog li cov nplooj ntawv number case tsis tuaj yeem hloov mus rau hauv cov substrate. Thaum lub tshuab luam ntawv siab tsis sib npaug lossis tsis txaus, cov txheej txheem number case ntawm nplooj ntawv tsis tuaj yeem tsis sib xws lossis hloov pauv mus rau hauv substrate, kom cov number case txheej ntawm cov khoom luam ntawv yog concentrated lossis inked. Tsis tas li ntawd, yog tias cov txheej txheem ntawv siv lub hauv paus ntoo los luam ib cheeb tsam loj ntawm lub phaj, vim tias lub hauv paus yog ib qho yooj yim los tsim compression deformation, thiab lub firmness tsis txaus, tus number case txheej ntawm cov luam ntawv feem ntau yog cuav thiab tsis sib xws, batch ntawm cov khoom kuj muaj feem xyuam rau number case concentration thiab inconsistency. Yog li ntawd, cov txheej txheem letterpress yuav tsum siv cov phaj kub los xyuas kom meej cov ntawv luam tawm zoo.
5. Ink viscosity loj dhau lawm thiab txheej number case yog tuab dhau los ntawm cov xim tsis sib xws. Thaum cov hlab ntsha ntawm cov menyuam hlau me me dhau lawm, thiab qhov sib txawv ntawm cov ntawv hlau thiab cov hlau cov menyuam loj dhau lawm, ces cov xim txheej ntawm tus number case hopper yog tuab, thiab nws tsis yooj yim rau kev sib npaug, thiab tom qab ntawd. pauv mus rau lub phaj, feem ntau zoo scale me ntsis, uas yog vim lub adsorption quab yuam ntawm daim ntawv ntawm tus number case yog tsawg tshaj li qhov adhesion ntawm tus number case ntawm daim ntawv luam ntawv.
6. Inker hlau cov menyuam sib tsoo poob lub voj voog thiab steel ntawv ntug nkhaus loj, ua rau inking kom muaj nuj nqis imbalance uas ua rau cov number case tsis sib xws. Hauv cov xwm txheej no, kev kho kom tsim nyog yuav tsum tau ua kom cov hlau cov menyuam nyob ze rau qhov sib npaug li qhov ua tau thiab txhawm rau txhawm rau cov npoo ntawm cov ntawv hlau rau hauv ib txoj kab ncaj nraim, kom tus number case tsim los ntawm tus number case rau ntawm tus number case. hopper tuaj yeem tswj tau yooj yim, kom tsis txhob muaj xim tsis sib xws hauv kev luam ntawv.
7. Tsis zoo rau cov menyuam precision, kev hloov tsis raug rau cov menyuam txoj haujlwm thiab cov colloid nyuaj heev ua rau tsis sib xws ntawm tus number case. Thaum cov roj hmab cov menyuam lub taub hau hnav los yog cov menyuam roj hmab tsis zoo nrog cov hlau cov menyuam, qhov sib txawv ntawm cov cwj mem ntau dua thiab hloov pauv tsis tuaj yeem ua tiav. Tsis tas li ntawd, thaum lub colloid ntawm inking cov menyuam yog ib qho nyuaj, nws yog ib qho yooj yim rau plam nyob rau hauv cov txheej txheem ntawm layout inking, ua rau qhov tsis xws luag ntawm luam ntawv bar cim thiab inking inking tsis sib xws, cuam tshuam rau cov luam ntawv zoo ntawm layout.
