Kos duab yog ib qho teeb meem uas feem ntau ntsib hauv gravure printing. Nws muaj ntau yam xws li lub tshuab luam ntawv gravure, plhaub lub tog raj, tus kws kho hniav, lub chaw luam ntawv, tus lej, thiab lwm yam.
Teeb duab kuj yog hu ua daim duab thiab pib. Thaum cov ntawv ntawm tus number case thiab cov xim ntawm kev loj hlob ntawm tus cwj pwm txawv txawv, lub degree ntawm kev kawm kuj txawv. Feem ntau, qhov tshwm sim tshwm sim ntawm dub, cyan thiab magenta yog pom meej, thiab nws feem ntau tshwm rau ntawm ib cheeb tsam loj ntawm qhov ntiav network.
Peb ntsuam xyuas cov qauv xaim uas tsim los ua peb hom: kos duab ntawm qhov chaw ntiav ntiav mesh, kos cov cwj mem zeeg hauv cov xim pob zeb, thiab kos cov duab tsis tas li.
Kos rau hauv qhov chaw ntiav mesh
1. Tshem tawm cov qauv tshwm sim los ntawm qhov tsim cov phaj tsim
Cov ntawv pov thawj muaj kev pom zoo hauv qhov tsim thiab phaj kev tsim ntawm thawj. Nco ntsoov xav txog kev xav txog kev luam ntawv, sim tsis txhob luam tawm ntiav mus tob; dub, magenta version yog qhov feem ntau yuav tshwm nyob rau hauv ntiav mesh, tshwj xeeb tshaj yog cov dub version, vim lub coarse cov ntsiab lus nyob rau hauv cov number case, thaum cov dub net yog heev ntiav, ib tug Dot Almost tsis muaj cov ntsiab lus yuav loaded, yog li nws nws yooj yim dua. Yog li ntawd, ib qho chaw loj ntawm dub thiab ntiav ntiav yuav tsum muab teev ua ib hom ntawv tshwj xeeb grey, txo cov luam tawm nyuaj thiab cov nqi seem.
2. Siv cov zais ntsej muag kom tsis txhob kos duab
(1) Kev xaiv ntawm tus cwj pwm. Cov tawv nqaij ntawm cov xim chrome plated yog HV850 ~ 1100. Lub zuaj tawv ntawm lub khob ntws yuav tsum qis dua qhov hardness ntawm lub phaj. Nws yog hais txog HV600. Cov hardness yog tsawg tsawg. Tus number case yog tsis huv. Lub zog yog siab heev, uas yuav ua rau kev siv lub phaj thiab ua rau hauv lub riam. , cuam tshuam qhov zoo ntawm cov khoom luam tawm.
(2) Lub flatness ntawm squeegee. Thaum txhim kho lub khob ntim, lub hau yuav tsum tau flattened, thiab lub screws yuav tsum tau tightened ntawm nruab nrab mus rau ob sab. Nws yuav tsum tsis txhob ua tiav hauv ib kauj ruam. Nws yuav tsum rov qab ob peb zaug los txhawm rau kom muaj lub zog ntawm lub ntsej muag.
(3) Lub ntse ntse ntawm tus cwj pwm. Kev sib tsoo cov cwj mem zeeg nrog 600 # cov xuab zeb dej los yog 2 # metallographic sandpaper, los yog siv lub tshuab tshwj xeeb ntse rau grind rau sab nraum qab ntawm lub ciam teb rau hauv lub qhov ncauj tawm ntawm 25 °, txawm tias cov riam tshiab yog hauv av.
(4) Lub kaum ntse ntse scraper. Lub kaum ntse ntsej ntawm tus kws kho mob hniav yog tsawg tshaj li qhov qub luam ntawv, thiab qhov kev ncua deb ntawm qhov chaw sib cuag ntawm tus kws kho mob hniav thiab cov ntawv xov xwm thiab cov lus taw qhia luv zog.
3. Cov cwj mem zoo tsim nyog rau kev tiv thaiv kev kos duab
(1) Thaum muaj qhov loj ntawm lub qhov ntaiv lossis qhov kev hloov ntawm daim phaj ntu, tus number case nrog kev zoo dua yuav tsum raug xaiv kom tsis txhob muaj cov xim ntawm cov xim uas tsis yog xim los ua teeb meem. Feem ntau, fineness ntawm tus number case yog 15μm, thiab tus cwj pwm xoom feem ntau yog ntxhib mus rau lub cwj mem. Kev puas tsuaj rau cov phiaj yog loj heev.
(2) Thaum blending inks, nyob rau hauv qhov chaw uas tsis cuam tshuam lwm cov qauv nyob rau tib lub phaj, xav siv cov kuab tshuaj qaug kom qhuav, thiab tsis ntxiv cov dej caw ntau ntxiv xws li ethyl acetate los tiv thaiv tus cwj los ntawm kev hloov thiab qub. sau.
(3) Xyuas kom tseeb tias tus number case viscosity yog me ntsis thiab ruaj khov. Zus tau ntawm cov xaim muaj kev sib raug zoo nrog kev xauv npo. Feem ntau hais lus, qhov siab zog ntawm tus cwj pwm ntawm tus cwj pwm, nws yooj yim dua yog tsim cov kab txiav hauv kev luam ntawv. Tsis tas li ntawd xwb, vim muaj kev sib txawv ntawm ntau hom tshuaj muaj ntau, cov nyiaj ntxiv hnyav ntxiv tsis zoo li qub. Thaum formulating inks, muab xa mus rau cov ntaub ntawv uas muab los ntawm cov lej ntawm cov lag luam, thiab muab lawv cov ntawv luam tawm thiab luam tawm cov khoom los nqa ua haujlwm.
Teeb duab ntawm lub pob zeb nris los ntawm txoj hauj lwm riam
Kev kos duab ntawm lub pob zeb ntawm lub nrig ntawm txoj hauj lwm riam yog tshwm sim los ntawm kev tshem cov cwj pwm ntawm qhov xim ntawm lub pob zeb, muab qhov ntug ntawm lub luam ntawv xim thaiv kom tawg tau, feem ntau yog ob peb millimeters ntawm luv luv xaim, lub ntsiab yog vim tias tus number case viscosity loj dhau thiab cov ink Number excessive feem ntau yog crystallized. Txoj kev daws teeb meem yog raws li nram no.
1. Lim tus cwj mem thiab ntxiv ib qho tshiab ntawm cov cwj mem tshiab thaum siv.
2. Kho lub kaum ntse ntse los ntawm tus kws kho mob kom tsawg thiab txo qhov kev ncua ntawm qhov chaw sib cuag ntawm tus kws kho mob thiab lub phaj thiab lub thwj cim.
