Kev Paub Txog Xim Xim Printing Design

Hauv kev tsim luam ntawv, peb lub ntsiab xim ntawm tus number case yog sib xyaw ua ke sib txawv kom tau txais cov xim uas xav tau cov xim xim xim. Qhov ceev ntawm peb lub hauv paus inks ntawm lub tshuab luam ntawv substrate hauv kev tsim luam ntawv thiab seb lawv puas yog thiab sib npaug muaj kev sib raug zoo nrog cov neeg ua haujlwm tsim. Txawm hais tias cov neeg tsim qauv luam ntawv tsuas tuaj yeem ntsuas thiab teeb tsa tus number case ceev nyob rau hauv ib qho kev txwv, qhov ntom ntom no tuaj yeem pab cov neeg ua haujlwm luam ntawv kom tau txais ntau hom xim xim, tsis hais seb tus number case yog pob tshab lossis cov substrate yog dawb huv. Hauv kev tsim luam ntawv, peb tuaj yeem yooj yim pom cov kev ceev no hauv ntau yam kev tshaj tawm: xws li hauv FIRST thiab SWOP cov qauv.
Hauv kev tsim qauv luam ntawv, raws li tus number case ntom ntom tau teev tseg hauv cov lus qhia, txhua tus number case overlay ib ntu tuaj yeem siv tau, xws li YMC, YCM, CMY, CYM, MCY, lossis MYC. Tab sis puas yog txhua qhov ntawm cov kab ke no tsim cov xim tib yam hauv kev luam ntawv? Qhov tseeb, tsis muaj.
Txawm hais tias qhov tseeb qhov ceev yog tswj nyob rau hauv tus nqi kiag li, txhua qhov sib tshooj sib tshooj hauv kev luam ntawv yuav ua rau cov xim sib txawv ntawm cov xim liab, ntsuab, thiab xiav, vim tias cov qauv siv hauv txhua tus qauv luam ntawv muaj lawv tus kheej cov khoom sib txawv, xws li tus number case opacity uas cuam tshuam rau tus nqi them. Yog li ntawd, lub zog saum npoo ntawm cov kua nplaum qhuav txheej uas tau luam tawm ua ntej yuav cuam tshuam rau cov yam ntxwv adhesion ntawm cov ntawv ntub dej uas tau luam tawm tom qab.
Lub zog npog ntawm cov xim daj yog qhov tsis zoo, thaum cov xim ntawm magenta thiab cyan pigments yog qhov zoo. Txawm li cas los xij, lub zog saum npoo ntawm cov xim daj yog siab heev.
Thawj kauj ruam hauv kev tswj xim hauv kev tsim qauv yog los txiav txim siab qhov kev txiav txim siab zoo ntawm tus cwj mem inking thiab qhov sib npaug ntawm qhov ntom ntom uas tuaj yeem muab qhov dav xim gamut.
Lub koom haum GATF tau tsim ib daim duab yooj yim xim hexagonal ntau xyoo dhau los kom pom qhov sib piv ntawm cov xim sib txawv. Lub densitometer tuaj yeem tso saib qhov zoo ntawm cov xim los ntawm kev ntsuas qhov sib txawv ntawm lub ntsej muag, qib grey, thiab xim xim, thiab sib piv nrog peb xim thawj.
Piv txwv li, nyob rau hauv daim ntawv qhia xim hexagonal, peb lub ces kaum uas tsis nyob ib sab sawv cev rau peb lub ntsiab xim ntawm tus cwj mem zoo tagnrho (YMC), thaum lwm qhov peb fab sawv cev rau cov xim sib xyaw xim (RGB). Qhov nruab nrab ntawm lub hexagon sawv cev rau cov xim nruab nrab (los ntawm dawb mus rau grey rau dub). Qhov muaj zog ntawm tus number case xim siv, qhov ze nws yog rau txhua lub ces kaum, thiab qhov deb yog los ntawm cov xim nruab nrab.
Thaum cov xim luam ntawv thiab cov xim sib xyaw tsim los rau kev luam ntawv tiag tiag tau muab faib rau hauv daim duab xim hexagonal, qhov ntom ntom, xim sib txawv thiab grey qhov tseem ceeb ntawm thawj xim inks (CMY) thiab cov xim sib xyaw (RGB) tau tshwm sim.
Vim tias tus number case tsis zoo tagnrho, qhov kev faib tawm hexagonal (irregular) yuav tsis zoo ib yam li tag nrho cov xim zoo nkauj hexagonal daim ntawv qhia, tab sis nws tseem tuaj yeem siv rau kev luam ntawv zoo. Yog li ntawd, siv txoj kev GAFT kom ua tiav qhov tsis xwm yeem hexagonal faib los tso saib cov ntaub ntawv xim ntawm peb lub ntsiab xim thiab cov xim sib xyaw hauv cov qauv luam ntawv tuaj yeem ua rau qhov zoo tshaj plaws ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.
Los ntawm kev ntsuas qhov loj ntawm thaj chaw xim xim, tag nrho cov xim ua haujlwm ntawm tus number case thiab qhov sib piv ntawm cov xim tsim xim tuaj yeem txiav txim siab. Tau kawg, thaj tsam loj dua, qhov zoo dua.
Lwm qhov tseem ceeb ntawm qhov ntom ntom kuj tseem tuaj yeem muab faib ua ib feem ntawm kev ntsuas kev sib txuas rau kev luam ntawv, xws li 25%, 50.5%, thiab 75.5% dot ntom qhov tseem ceeb ntawm cov xim.
Yog tias qhov kev faib tawm ntawm lwm cov xim muaj nuj nqis yog concentrated, nws qhia tau hais tias tus qauv luam ntawv yog tswj tau. Hloov pauv, yog tias qhov kev faib tawm tsis muaj zog, nws txhais tau hais tias cov qauv luam ntawv tau poob kev tswj hwm thiab tsim nyog yuav tsum tau ua.
