Cov nyhuv rau ntawm tus zauv cim xim ntawm cov ntawv luam tawm
Phaj ntawv luam tawm yog txheej txheem siv ntau zus. Yuav ua li cas los txhim kho qhov muaj txiaj ntsig zoo thiab qhov tsim tau cov xim ntawm cov xim yog tsim nyog ntawm kev ntsuam xyuas thiab kev sib tham.
Txoj kev siv qhov muag ntawm cov xim muaj qhov muag tau yog ib qho tseem ceeb los ntsuas qhov zoo ntawm cov ntawv luam tawm. Muaj ntau ntau yam uas yuav cuam tshuam txog cov xim ntawm cov ntawv luam tawm.
(-) Cov nyhuv ntawm cov thickness thiab cov viscosity ntawm cov ntawv luam tawm tus lej nplooj ntawm cov xim ntawm cov luam
Moderate printing ink layer yog ib qho kev ntsuas tseem ceeb kom paub tseeb ntawm tus lej ntawm daim ntawv luam tawm thiab tiv thaiv cov teeb meem luam tawm ntawm cov quav. Yog hais tias tus number case txheej yog thicker, cov viscosity nyhav kom nce, thiab daim ntawv yog yooj yim generated, uas cuam tshuam lub uniformity ntawm tus number case xim ntawm cov ntawv luam tawm. Yog hais tias cov ntawv luam tawm txheej hauv plhaub taum plig thiab cov ink viscosity tsis txaus, cov luam tawm ntawm cov xim muaj zog tsis muaj zog, thiab cov khoom siv muag pom cov nyhuv yog nws tseem phem. Raws li lub tshuab luam ntawv tig mus ntev zog los yog kev luam ntawv nce ntxiv, kev sib txhuam coefficient tsub kom dua thiab cov cim hauv qhov kub kub nce. Yog li ntawd, tus number case ua thinner thiab nws cov viscosity txo raws. Yog li no, cov mob no yuav tsum tau xav txog thaum kho tus cwj mem los xyuas kom muaj ib qho kev luam tawm xim xim rau cov khoom ua khoom siv. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntau lawm, qhov txo ntawm tus viscosity ntawm tus number case yog tsis pom nriav. Hauv cov theem pib ntawm cov luam ntawv, tus number case xim ntawm cov khoom luam tawm kuj yog cov tuab, thiab nws yuav lighter yav tom ntej. Lub kaum sab xis ntawm cov tub ntxhais hloov xa tub rog tuaj yeem tsim nyog kho kom haum. Tus lej ntawm tus lej yuav ua rau sab pem hauv ntej thiab sab nraum qab ntawm cov xim xaj. Tsis tas li ntawd, yuav kom tsis txhob muaj qhov txawv ntawm tus cwj pwm ntawm tus cwj pwm ntawm lub cev los ntawm kev muaj zog thiab cuam tshuam qhov nyiaj tshuav ntawm tus number case ntawm cov luam ntawv, kev sib cuag ntawm txhua tus menyuam roj hmab thiab cov hlau plawg yuav tsum tsis txhob nruj heev, thiab lub colloid yuav tsum tsis yuav nyuaj heev, thiaj li txo qis tshav kub thiab muab tus cwj mem kom zoo. concentration.
(2) Feem xyuam ntawm kev luam ntawv siab ntawm cov xim ntawm cov khoom luam tawm
Kev nyuaj siab yog ib qho tseem ceeb rau kev hloov ntawm kev luam tawm. Txij li ntawm qhov saum npoo ntawm lub phaj luam ntawv tsis yog kiag li ca, qhov saum npoo ntawm daim ntawv no yog qhov raug nplua tsis zoo thiab tsis sib thooj. Yog hais tias lub tshuab luam ntawv tsis txaus lossis tsis sib haum, lub tshuab luam ntawv nyob rau ntawm lub luam tawm sab hauv Ink yuav tsis pom qhov tsis sib haum. Yog li, qhov zoo tshaj plaws luam ntawv yog raws li "three flats" (piv txwv li, lub phaj ntiav yog tiaj tus piv nrog cov tub ntxhais uas muaj lub plhaub thiab lub raj xa mus rau kev sib tiv tauj zoo), thiab cov lej ntawm cov kua thawv uas ua rau thev naus laus zis. Mus ua kom tau zoo dua cov xim tshwj xeeb ntawm cov xim. Yog hais tias lub tshuab luam ntawv tsis txaus los sis tsis sib haum, lub caws pliav thiab cov ntawv phaj ntub tsis muaj teeb meem. Los ntawm qhov ntxiv ntawm tus lej ntawm tus cwj pwm, qhov muag pom tau zoo ntawm tus cwj pwm xim ntawm qhov tsim muaj peev xwm txaus siab, tab sis qhov no tsis tsuas yog nce lub siab ntawm tus cwj mem, tab sis kuj yooj yim tshwm sim. Nws tsis yog qhov tsim nyog tias qhov teeb meem luam tawm yog lo av.
(3) Cov khoom ntawm cov roj hmab rau cov tub ntxhais cov ntawv luam tawm thiab xim muaj xim
Raws li qhov sib tw thiab cov txheej txheem luam ntawv muaj kev txhawj xeeb, seb cov ntawv luam tawm tau cov xim yam xav tau xim muaj kev sib raug zoo nrog rau qhov zoo ntawm rubber cov menyuam. Cov khoom siv luam ntawv xim luam tawm muaj tsib los yog rau los yog ntau tshaj peb hom ink numbered hloov rollers, number case distributor rollers thiab case rollers. Ntawm lawv, cov lej number case hloov thiab cov quav rau cov tub ntxhais muaj lub zog zoo rau ntawm tus cwj pwm xim. Qhov zoo tshaj ntawm cov roj hmab rau cov tub ntxhais hluas feem ntau tshwm sim hauv qhov sib txawv ntawm elasticity, viscosity, nruab nrab ntawm lub ntiajteb txawj nqus thiab qhov chaw tiav, thiab viscosity uas tsuas yog cuam tshuam cov xim ntawm tus cwj pwm yog viscosity. Hauv cov txheej txheem luam ntawv, cov roj hmab uas rubber tsuas tswj tau ib qho viscosity kom paub tseeb tias tsis muaj tus lej ntawm tus lej ntawm cov ntawv luam tawm rau cov ntawv luam tawm ntawm lub luam ntawv. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntau lawm, qhov uas rub tawm ntawm cov roj hmab tsis yog nyob ruaj khov. Ua ntej, vim tias muaj cov hmoov av ntxiv ntawm cov hmoov av, qhov uas ua rau lub cev nqaij daim tawv tuaj yeem cuam tshuam. Secondly, lub tackifier (piv txwv li, glycerin) nyob rau saum npoo ntawm lub gel nce nrog kub thiab siv lub sij hawm. Thaum nws raug ncua thiab poob lawm, qhov uas ua rau ntawm qhov chaw rubber ntawm cov roj hmab rub tawm yuav maj mam txo, thiab tus cwj pwm tsis txaus (absorption) yuav ua rau poob qis, uas yog cuam tshuam rau ntawm tus lej xim ntawm cov ntawv luam tawm. Yog li ntawd, cov phaj luam ntawv yuav tsum siv cov roj pleev polyurethane roj hmab ruaj khov. Yog tias luam ntawv luam tawm ntau, cov roj hmab rub yuav tsum tau muab tu rau lub sijhawm.
(4) Feem xyuam rau qhov sib txawv ntawm qhov huv ntawm daim ntawv ntawm tus lej xim ntawm cov ntawv luam tawm
Qhov tseeb, kev sib raug zoo ntawm daim ntawv thiab tus number case yog qhov nyuaj. Yog hais tias koj tsuas xav txog xim ntawm ib phau ntawv, koj yuav tsum nco ntsoov tias smoothness ntawm qhov saum npoo ntawm daim ntawv muaj ib qho kev sib raug zoo nrog cov xim ntawm tus number case. Yog hais tias lub siab ntawm txhua phaj yog zoo ib yam, tus smoothness ntawm cov ntawv ntawm daim ntawv yog inversely proportional rau tus nqi ntawm tus number case consumed, thiab tus nqi ntawm number case absorbed yog tus smoother me me, thiab conversely, tus nqi ntawm number case absorbed loj. Yog li, yog tias muaj qhov sib txawv ntawm lub hauv ntej thiab sab nraum qab ntawm daim ntawv, qhov yuav ua kom tus nqi ntawm tus number case thiab lub siab yuav tsum tau txais raws li qhov tsim nyog kom tsim nyog kho. Nws yog txoj kev cai luam tawm lub nplaum ua ntej, thiab qhov siab thiab tus nqi xaj yog qhov tsim nyog nce thaum qhov ntxhib saum npoo luam kom zoo, kom txhua tus zoo thiab tsis pom muaj xim xim tag nrho muaj qhov pom kev zoo. Kev xyaum tau pom tias cov nyhuv ntawm txoj kev siv saum toj no zoo dua li qhov ua kom muaj tus cwj pwm ntau, thiab cov ntawv luam tawm zoo dua.
(5) Kev hloov ntawm lub teeb hloov ntawm cov xim ntawm cov khoom luam tawm
Cov teeb pom kev zoo uas feem ntau qhia txog cov xim ntawm cov ntawv luam tawm yog peb hom hnub ci, lub teeb pom kev zoo, thiab lub teeb hluav taws xob. Peb lub teeb pom kev muaj ntau yam kev sib txawv ntawm cov teeb meem, thiab cov xim ntawm lub teeb pom kev zoo sib txawv. Lub gaze yog dawb huv lub teeb, lub teeb pom kev zoo yog lub teeb nyob rau hauv cov xim dawb, thiab lub teeb hluav taws xob yog reddish thiab me ntsis yellowish. Txawm hais tias lub hnub ci thiab qhov muag pom lub teeb pom kev zoo me ntsis zoo sib xws, qhov txawv ntawm qhov ob yuav tsum tau xav txog thaum paub cov khoom zoo dua. Cov nyhuv ntawm lub teeb rau ntawm cov cim ntawm tus cwj pwm tsis yog tsuas muaj feem xyuam nrog lub teeb ci, tiam sis kuj yog rau qhov siv ntawm lub teeb thiab lub kaum sab xis ntawm lub teeb. Nyob rau tib lub teeb pom kev, qhov kev siv ntawm lub teeb pom ntawm cov qauv no yog txiav txim siab los ntawm kev sib nraus ntawm tus qauv thiab lub teeb qhov chaw, thiab cov nyob ze yog muaj zog thiab qaug zog tsis muaj zog. Qhov tseeb ntawm lub teeb pom kev zoo yuav tsum yog tias lub kaum sab xis ntawm cov xwm txheej sib npaug yog sib npaug ntawm lub kaum ntse ntse ntawm txoj kev xav. Lub teeb irradiation ntawm cov pov thawj inevitably muaj ib nrab refraction, tab sis nws tsis muaj ntau lub cawv rau cov cim ntawm number case. Thaum paub qhov xim ntawm cov ntawv luam tawm, txawm nws yog ib hnub los yog hmo ntuj, qhov kev siv ntawm lub teeb ci thiab qhov irradiation angle yuav tsum zoo tib yam los tiv thaiv cov xim ua haujlwm los yog tus number case xim los ntawm mutated ua ntej thiab tom qab lub inking kev yuam kev.
(6) Kev tsis zoo yuav tsis raug rau qhov xim ntawm tus cwj mem
Rau cov khoom uas muaj xim xim, seb lub taub ntawm txhua cov xim phaj yog muaj tseeb yuav muaj kev cuam tshuam zoo heev rau ntawm Hawj Xeeb. Qhov tseeb hue nyhuv ntawm overprinting kuj zoo, thiab hawj ntawm cov khoom luam tawm uas tsis muaj tseeb overprinting yuav tau deviated. Qhov no yog vim qhov sib txawv hauv txoj hauj lwm luam los ntawm cov dots ntawm txhua qhov xim, uas inevitably ua ib lub nrig txog kev pom chromatic aberration. Yog li ntawd, rau luam yeeb yaj duab reticulated, overprinting yuav tsum yog kom paub meej tias cov hawj luam xov xwm ua tau raws li txoj cai. Txhawm rau tiv thaiv kom tsis txhob muaj kev sib raug zoo los ntawm kev ncab ntawv thiab kev hloov, cov xim txawv los ntawm qhov kev tshaj tawm, rau cov kev xav tau ntawm cov xim zoo nkauj rau cov khoom noj, ntau lub tshuab yuav tsum tau siv los ua kom tiav cov xim luam ntawm ib zaug los txhim kho qhov zoo ntawm overprinting. Tsis tas li ntawd, daim ntawv yuav tsum tau muab dai kom txo qhov kev hloov ntawm cov nplooj ntawv luam tawm thaum luam ntawv.
