Yog tias koj nug cov nqe lus nug: Yam txheej txheem twg yog qhov tseem ceeb tshaj plaws thiaj li tau txais kev luam ntawv zoo? Cov lus teb yuav yog: cov txheej txheem luam ntawv yog qhov tseem ceeb. Cov txheej txheem no yog qhov qhia tau zoo ntawm txhua qhov txheej txheem ntawm cov txheej txheem luam ntawv. Nws yog ib qho ua ke ntawm tus cwj mem, daim ntawv thiab tag nrho cov txheej txheem nruab nrab, tsim ib qho zoo heev, tag nrho lossis tsis tsim nyog luam.
Lub hom phiaj qhov kawg ntawm kev luam ntawv yog los tsim qhov zoo tshaj plaws tau luam tawm nrog cov ntaub ntawv teev tseg. Cov khoom yuav tsum muaj cov xim raws tu tub tu kauj, zoo ib yam thiab ua ntsej muag. Rau ib pawg ntawm cov khoom uas tsim tawm tsis tu ncua, cov khoom tsim nyog yuav tsum muaj qhov pom tau zoo sib xws, vim muaj pua pua lub zog uas cuam tshuam rau cov khoom siv ntawm qhov khoom muag, peb yuav tsum ntsuas thiab tswj cov yam ntxwv zoo ntawm cov ntawv luam uas muaj kev cuam tshuam loj tshaj plaws pom cov yam ntxwv ntawm cov khoom. .
Tus neeg teb xov tooj nias yuav tsum kho cov xovxwm rau ib tus lej muab, daim ntawv thiab phaj kom zoo dua rau txoj kev luam ntawv. Cov kev kho no yuav tsum txo cov teebmeem ntawm cov txheej txheem, uas yog cov xovxwm los tsim cov khoom tsim nyog uas phim cov pov thawj qhov pov thawj. Tom qab ntawd, tus neeg teb xov tooj xovxwm yuav tsum tswj cov txheej txheem luam ntawv kom tsim cov khoom luam tawm uas tsis hloov raws li cov xim tshuav nyiaj li cas, lub suab nrov dua, thiab cov ntaub ntawv sau npe.
Thawj kauj ruam hauv txoj kev luam cov txheej txheem luam ntawv yog los tswj cov txheej txheem luam ntawv. Sim tswj cov xovxwm uas tsis ua haujlwm zoo yog qhov nyuaj thiab cov txheej txheem luam ntawv yuav poob sai tswj. Ib txoj haujlwm zoo uas ua haujlwm tau ua haujlwm tsis muaj teebmeem rau lub sijhawm ntev, thiab nws tuaj yeem ua tau me ntsis offset tsis tau ua cov khoom tsis raug cai. Txhawm rau optimize thiab tswj cov txheej txheem luam ntawv, nws yuav tsum to taub yog dab tsi thiab yam ntxwv yam twg thiab yog qhov feem ntau raug.
Muaj qee yam teeb meem ntawm cov teeb meem zoo xws li: adhesion, number case, colour variation, plaub hau rub, ghosting, overprinting, non-duab ib nrab inking, txom overprinting, excessive hmoov, smudging, duab ntxoov ntxoo, rov tom qab, dawb me ntsis, Kev, vaub kib, thiab wrinkles.
Lub ruaj ntseg ntawm cov khoom zoo yog ib qho tseem ceeb, thiab nws ua rau kev txiav txim siab txo cov nyiaj poob haujlwm thaum lub sij hawm zoo sij hawm. Factories yuav tsum tau muab cov kev ua haujlwm thiab kev ua haujlwm zoo.
Thawj, qhov txawv txav luam tawm
Cov ntawv luam ntawm cov ntawv luam tawm hauv kev lag luam ntawm lithographic offset printing presses muaj xws li cov khoom poob nyiaj, qhov sib txawv ntawm qhov sib txawv, qhov deformation, overprint, ink layer thickness, thiab ink hue. Ntsuas dej npau yas, pam daim tawv, pam thickness, ambient temperature, txhuam cov pwm ntawm qhov chaw, ziab tshav kub, ziab tsho kub, luam ntawv ceev, tshem tawm keeb kwm, tag nrho overprint ratio, tag nrho xaj npo, dov hardness, meem thickness, dov siab, web force, printing version hnav thiab hais txog.
Cov qhob saum toj no tsis yog txhua yam uas yuav ua rau luam, tab sis nws muaj peev xwm tau piav qhia tias muaj ntau qhov ntau ntawm cov tshuab luam ntawv. Txawm tsis muaj teeb meem zoo li cas tus neeg siv tshuab luam ntawv ua haujlwm zoo, cov kev hloov yuav tshwm sim tas li. Yuav kom ntseeg tau qhov ruaj ntseg ntawm kev luam ntawv. Tus neeg teb xov tooj yuav tsum txiav txim siab txog cov kev hloov uas tshwm sim thiab tsim nyog hloov.
Thib ob, sim, sampling thiab hloov
Txhawm rau optimize xovxwm ua rau nws qhov chaw zoo tshaj plaws, tus neeg teb xov tooj yuav tsum siv qhov ntsuas los ntsuas ntau npaum li ntau tau, xws li ink viscosity, phaj thiab pam ob sab phlu, printing press, dej tov thiab nws cov pH, number case Roll hardness, txheeb ze dej ntsiab lus ntawm daim ntawv, kev hloov ntawm cov quav cuav, thiab lwm yam tuaj yeem ntsuas thiab tswj tau.
Ntev npaum li txheej txheem luam ntawv zoo dua nrog cov txheej txheem luam ntawv, tus neeg siv tshuab luam ntawv yuav tswj tau qhov zoo ntawm qhov khoom los ntawm kev ntsuam xyuas tus qauv thiab kho nws. Feem ntau, ntau txoj kev ua rau cov ntawv sau tawm tuaj yeem ua haujlwm rau ib leeg, thiab tus neeg ua haujlwm luam tawm tau tswj cov txheej txheem luam ntawv nrog tsawg dua kev hloov. Yog tias qhov kev hloov kho tau yog thaum cov txheej txheem luam ntawv pib los ntawm thawj qhov kev qhia ntawm kev tswj, ces cov kev tsis sib thooj hauv kev luam zoo yuav tsis tseem ceeb.
Lub hom phiaj ntawm kev tswj cov txheej txheem yog kho qhov sib txawv ntawm txoj kev los ntawm kev hloov cov kev coj ua ntawm kev sib txawv ua ntej poob kev tswj thiab ua cov khoom puas.
Qhov no yuav tsum yog tus neeg teb xov tooj xovxwm kom zoo rau kev ua haujlwm, feem ntau soj ntsuam cov khoom thiab saib cov kev hloov hauv cov kev luam tsis zoo uas qhia cov khiav tawm ntawm cov khiav haujlwm. Lub ntse ntse ntawm tus neeg teb xov tooj xovxwm ntxiv rau txoj kev tswj cov cuab yeej yuav pab kom cov khoom tsim kom ruaj khov. Txawm hais tias cov xovxwm tseem ceeb me ntsis rau lub sij hawm luam tawm, nws tuaj yeem kho sai. Qhov sib txawv ntawm qhov feem ntawm cov ntawv luam tawm yuav tsis yog obviously.
Thaum muaj ntau lub zog ua haujlwm rau ib leeg, qhov kev pom zoo ntawm kev txhim kho kom zoo yuav tsum ntseeg tau, thiab qhov tseem ceeb tshaj plaws thiab cov teebmeem yuav muab los tham tom qab.
