Classified los ntawm cov ntawv sau tawm
Raws li daim ntawv npaj tawm, luam tawm tau muab faib ua plaub pawg: letterpress printing, lithography, gravure printing thiab stencil printing.
Yog hais tias lub iav magnifying nrog loj magnification siv rau kev soj ntsuam kom zoo thiab sib piv, nws muaj peev xwm roughly txiav txim siab uas luam tawm nws yog nyob rau hauv cov tsos ntawm cov ntawv luam tawm.
Txhua tus lej sau rau ntawm kab yog piled nyob rau hauv ib lub thawv tooj liab los yog ib phaj concave hnab. Vim hais tias tus number case ntawm intaglio phaj feem ntau yog piled li nyob rau hauv ib tug tob zawj, tus number case yog thicker.
Cov duab yog faintly them nrog dawb kab, thiab qhov tsaus nti yog tuab, thiab qhov ci qaim yog lub teeb. Nws yog ib qho zom zaws. Qhov laj thawj yog vim li cas muaj ib kab kab dawb kab sib npaug yog faintly them. Qhov no yog vim hais tias qhov screen ntxiv nrog lub ziab qhuav los tiv thaiv cov hniav los ntawm scraping tus number case hauv lub zawj ntawm lub luam ntawv.
Qhov twg ntawm qhov chaw ntawm kab los yog dot yog ib tsos tsaus tsawv, cov npoo tsis zoo, thiab tsis muaj pawg, nws yog ib daim ntawv lithographic. Cov ntawv luam tawm thiab cov ntawv sau ntawm lub phaj yog cov tiaj tus, thiab cov npoo tsis sib haum vim dej yaig. Tam sim no, feem ntau cov xim luam tawm nyob rau ntau lub teb chaws luam tawm hauv lithography.
Qhov twg sab nraum qab ntawm daim ntawv luam tau muaj qhov cim tseg thiab cov cim, cov npoo ntawm cov kab lossis cov dots yog huv, thiab tus cwj mem yog lub teeb nyob rau hauv qhov chaw, nws yog ib tsab ntawv sau. Cov npoo ntawm cov ntawv sau nyhav yog hnyav hnyav thiab yog li muaj cov tswv yim me ntsis.
Nyob qhov twg hauv daim duab yog them nrog crepe, zoo li ib lub phab ntsa cement rau ntxuav pob zeb, qhov tsaus nti yog ib tsos tsaus tsawv, thiab lub teeb qhov ci yog sib zog. Tus neeg tsim khoom siv yog tsim los ntawm kev txhim khu tom qab txoj kev loj hlob los ntawm kev tsim cov luam yeeb yaj kiab thaum lub sijhawm phaj txiav txim siab, uas zoo ib yam li lub hav uas tsim los ntawm lub hauv paus, thiab siv los nqa tus cwj mem.
Lwm tus neeg xws li lub hwj, qhov chaw thiab cov rooj sib koom siab dav hlau, luam tawm ntau qhov chaw.
Classified los ntawm kev luam ntawv
Raws li cov txheej txheem luam ntawv, muaj cov tib neeg luam tawm thiab luam ntawv tsis ncaj.
Ncaj ncaj luam yog tias cov ntawv luam tawm ntawm tus xov tooj yog nyob rau hauv kev sib txuas nrog cov khoom uas yuav tsum tau muab luam tawm, thiab tus number case yog pauv mus rau cov ntawv luam tawm. Tag nrho cov ntawv sau presspress (cov hnab yas tshiab los yog cov yas yas ntawm cov lus teb) thiab gravure presses, zoo li cov tshuab lithographic tshuab luam ntawv lithographic, yog cov tib neeg luam tawm.
Txwv tsis pub luam tawm txhais tau tias cov ntawv luam tawm yuav tsum tau xa mus rau lub tog raj kheej (Lub tog raj kheej) ua ntej, thiab tom qab ntawd ces tus number case yog txav mus rau cov khoom siv luam tawm los ntawm pam lub tog raj kheej. Ib tug ntawm lawv yog hu ua cov roj hmab tshuab luam ntawv.
Ncaj nraim ntawm luam tawm tsab, luam tawm rov qab, luam tawm tsis pub luam tawm, thiab luam tawm zoo.
Classified los ntawm luam tawm tsab cai
Raws li cov ntawv xov xwm, muaj cov tshuab luam ntawv thiab cov khoom tsis yog luam tawm hauv kev luam ntawv, txoj ntsiab cai ntawm kev tsim cov teeb meem tau muab faib ua lub cev luam tawm (Lub Cev Loj Hlis) thiab tshuaj luam tawm (Chmiacal Printing).
Lub tshuab luam tawm lub cev txhais tau hais tias tus number case yog ib hom stacked load ntawm cov ntawv luam tawm. Yog tias tsis muaj cov ntawv luam, nws yog concave lossis convex. Nws yog txawv ntawm qhov siab ntawm cov ntawv luam tawm thiab tsis tuaj yeem siv nrog xaj kua mem. Yog li ntawd, ib feem ntawm cov ntawv luam tawm yog muab xa mus rau qhov teeb meem ntawm cov ntawv luam tawm, uas yog ib qho kev ua haujlwm ntawm lub cev. Feem ntau gravure printing, letterpress printing, stencil printing, lithography, thiab cov zoo li. Txhua yam yog lub tshuab luam tawm (luam tawm nplaum siab dua los yog qis tshaj qhov tsis pub luam tawm).
Tshuaj lom neeg txhais tau tias cov phaj luam ntawv tsis muaj ib feem ntawm cov ntawv luam tawm (uas tsis yog luam tawm) uas tsis muaj ntiv tus cwj pwm, thiab tsis yog vim tsis muaj qhov tsis sib haum los yog qhov tsis sib nkag ntawm lub ploj, tiam sis yog vim dej tshuaj, uas ua rau cov yeeb yaj kiab kom nqus dej thiab kua mem sau. . Cov ntawv luam tawm (qhov chaw luam ntawv) absorbbs number case thiab dej, thiab cov luam tsis yog kev luam dej tsis txaus thiab tsis kam muab xaj. Qhov kev sib koom ntawm cov dej thiab roj tseem yog lub cev tsis muaj teeb meem, tab sis nyob rau hauv cov txheej txheem luam tawm, cov ntawv tsis muaj qhov tseem ceeb yog muab tso rau hauv cov dab dej. Yuav ntxiv cov dej-absorbing thiab ink-repellent zaj duab xis, nws yog ib qho tsim nyog yuav ntxiv ib qho kua qaub thiab cov tshuaj zoo li gel kom muaj ib qhov chaw ntawm ib pawg carboxyl uas muaj mucus acid txheej, kom tsis txhob ntu luam tawm ntawm cov luam ntawv phaj tuaj yeem tsis pub los ntawm cov kab mob roj av, thiaj li hais tias nws tau raug luam tawm. Lub tshuab luam ntawv lithographic luam ntawv luam tawm yog rau pawg no.
Classified los ntawm kev luam xim
Raws li cov xim ntawm cov teeb meem luam tawm, nws muab faib ua ob hom: monochrome printing thiab multi-color printing. Monochrome printing tsis yog rau cov dub. Tus neeg twg uas qhia cov duab luam tawm hauv ib hom xim belongs rau pawg no.
Poly Color Pritning yog faib ua peb pawg: Cosing Method, Sau Txoj Cai thiab Zov Xim.
Cov xim li no yog ntxiv rau lwm cov xim nyob rau hauv kab ob kab hauv duab monochrome los ua kom pom tseeb thiab paub meej, uas yog qhov zoo rau kev nyeem ntawv. Hom no yog siv hauv cov luam tawm ntawm cov menyuam phau ntawv.
