Rau ob kob xim los yog ntau hom xim offset, cov txheej txheem overprinting wet-stacked, tsis zoo li cov txheej txheem ntub luam ntawm lub tshuab monochrome. Feem ntau, qhov ziab khaub zauv ntawm tus cwj mem qhuav yog 10 feeb, thiab thaum lub tshuab luam yeeb ob los sis ntau hom xim muaj ntau dua, lub sij hawm sib txawv nruab nrab ntawm ob xim luam tsuas yog li 0.5 vib nas this. Nyob rau lub sijhawm luv luv no, nws tsis tuaj yeem kho tus cwj pwm (tshwj xeeb tshaj yog cov khoom thaiv qhov) ntawm daim ntawv, uas yog qhov tseem ceeb tshaj plaws rau cov xim xim ntse phenomenon ntawm ob-xim lossis ntau xim xim ntawv luam ntawv tshuab. Lub ntsiab tseem ceeb uas cuam tshuam cov xim xim phenomenon ntawm offset tshuab luam ntawv yog raws li nram no.
1 ink viscosity
Feem ntau, cov xim xim sib lawv liag ntawm cov xim xim dub yog xim dub thiab xim daj, uas yog, thawj cov dub dub luam tawm ua ntej, thiab cov xim sib lawv liag raws li tus qauv ntawm cov xauv npab ntawm tus xaj kom qis los tiv thaiv cov xim tom kawg. Adsorb xim xim dhau los. Tab sis qee zaus daim ntawv sau npe yuav tsum kom tag nrho cov nplooj ntawv muaj xim zoo nkauj rau cov xim ntawm ib tus cwj pwm, xws li dub, ces cov xim dub yuav tsum tau muab tso rau hauv cov txheej kawg ntawm cov luam tawm (feem ntau yog xim dub tag nrho xim). Nyob rau lub sij hawm no, xav tias cov viscosity ntawm tus cwj mem kua dub yog loj, ib qhov nqi ntawm qhov uas yuav txo tau tus viscosity txo tus neeg mob yuav tsum muab ntxiv rau tus cwj mem xiav dub kom txo tau qhov siab, uas txo qhov tshwm sim ntawm cov xim sib tov.
2 number case coloring tus nqi
Hauv qhov ntau lawm, feem ntau ntawm cov xim tshuab siv cov thaub qab hauv tsev, thiab ntxiv, luam ntawv (feem ntau viscosity txo cov neeg ua hauj lwm) muab tso rau, yog li cov xim tus nqi qis dua tus qauv coloring tus nqi index. Yuav kom ua tiav tib lub zog tus nqi thaum lub sij hawm luam ntawv, nws yog qhov tsim nyog kom ntxiv tus nqi ntawm tus cwj pwm, uas yog, kom cov thickness ntawm tus number case txheej. Txawm li cas los xij, thaum tus cwj mem tsis qhuav, lub plhaub taum ploj zuj zus ntxiv, nws yooj yim dua los ntawm ib qho kev sib zog sab nraud (luam tawm siab, sib tev tsis sib haum), thiab xim xim yuav tsum tshwm sim.
3 Number ziab ziab ceev
Hauv kev siv ntau lawm, lub lag luam ntawm lub tshuab ua rau lub tshuab rubber rau kom sov li, tshwj xeeb tshaj yog thaum lub caij ntuj sov, lub khob ntawm tus cwj mem ntawm lub rubber rubber maj mam nce. Piv txwv, thaum lub tshuab luam yeeb ob lub xim liab thiab xim xiav, cov luam ntawv yog qhov qub, tab sis thaum luam tawm rau ntau nplooj ntawv, cov ntaub ntawv magenta muaj ib txoj kev xav tsaus ntuj. Nyob rau lub sij hawm no, lub tshuab roj hmab magenta yuav muab ntxuav tag nrog roj, thiab tom qab ntawd rov rov qab, tab sis xim yuav tsum zoo tib yam xim.
4 Duav qhov tswj kev tswj
Qhov zoo tshaj ntawm offset luam tawm cov khoom muaj kev sib raug zoo nrog cov ciav kua. Nyob rau hauv cov lag luam, peb feem ntau tswj cov dej luam tawm kom cov luam tawm dej kom zoo, yog li ntawd tus nqi ntawm tus cwj mem yuav tsum tau nce raws li, uas yog, peb feem ntau hais tias "dej" loj number case, qhov no yog ntau taboo. Vim tias qhov no yuav ua rau tus lej ntawm cov roj hmab, uas yog sib npaug ntawm txoj kab uas hla tus cwj pwm ntawm cov quav, ua rau lub siab khov, thiab ua rau lub plhaub taum ploj thiab kub dua thaum lub lag luam, thiab tus cwj mem ntau dua qhuav, series ntawm vicious cycles. Tsim cov xim sib tov.
5 Ua ib txoj haujlwm zoo ntawm kev tu lub PS version
Thaum luam tawm, nws yog qhov tsim nyog rau theem siab ntawm cov dej thiab tus cwj mem kua quav, xyuam xim rau pH tus nqi ntawm cov ciav dej, thiab tiv thaiv cov av qis ntawm ob sab (ob sab thiab ntu) uas tsis siv los ntawm kev luam phaj. Yog tias qhov dawb paug qias neeg, nws yuav pauv mus rau pam thiab lub hneev taw, thiab tom qab ntawd muab xa mus ntxiv rau ntawm cov pab pawg neeg, uas yuav ua rau kom muaj xim sib tov. Txuas ntxiv, xim xim thaum lub sijhawm phaj thiab lub teeb liab ntawm lub sijhawm luam tawm (tsuas yog siv los ntsuas qhov khoom ntom ntom ntu thaum lub sijhawm ntawv pov thawj) kuj tuaj yeem tshwm rau ntawm lub phaj, thiab qhov no yuav tsum tau kho thaum lub sijhawm luam tawm tiv thaiv xim sib tov.
