Cov lag luam yuav tsum tsim kom muaj cov qauv zoo, cov qauv ntaub ntawv thiab cov khoom siv xws li ntawv thiab cwj mem, cov txheej txheem kev ntsuas cov cuab yeej thiab lwm qhov pom kev, thiab tsim cov ntaub ntawv tswj hwm, thiab txhua tus kom ua raws li cov qauv. Cov duab, cov ntaub ntawv pov thawj, cov ntaub ntawv ICC ntawm lub tshuab luam ntawv, ntau yam ntawm cov tshuab luam ntawv, lwm yam zoo li yuav tsum tau ua tus qauv, thiab ntaus nqi hauv cov qauv thiab cov lus qhia. Hauv txhua qhov chaw uas cov ntaub ntawv qhia tau hais, cov ntaub ntawv tuaj yeem sau ua tiav thiab sau ua ke los ntawm kev sib tw. Qhov peb ua kom tiav ib leeg thiab nyob ntawm seb ib leeg yuav tsum ua kom muaj kev ruaj khov zoo thiab ua haujlwm tau zoo.
Ua kom pom cov duab ua technology yog lub hauv paus thiab qhov txuas ntawm cov ntawv luam luam zoo. Cov duab yuav tsum muaj kev tshaj lij, kev luam ntawm thawj cov ntaub ntawv thiab kev ua ntawm cov thawj cov ntaub ntawv yuav tsum tau koom nrog plaub qhov qauv ntawm cov qauv zoo (gray tshuav, suab tone, xim kho, sharpness li) los coj txoj haujlwm, thiab tsim kho tus plaub tus qauv tsis dhau ntawm kev sim. . Tom qab luam cov ntaub ntawv tiav tas lawm, nws yuav tsum kho thiab ua cov txheej txheem ntawm cov neeg tsis tuaj yeem ua cov ntaub ntawv tseem ceeb dua qub thiab zoo dua qub. Rau cov lag luam luam tawm hauv tsev kawm ntawv, cov chaw tiv thaiv cov ntaub ntawv pov thawj uas pom tseeb tias cov xim ntawm cov ntawv pov thawj hauv ob qho chaw yog tib yam.
Xaiv cov kev tswj xim
Muaj ntau ntau lub nruab kev tswj ntawm lub khw, xws li Adobe's Photoshop xim tswj qhov system, Apple's ColorSync xim tswj qhov system, thiab Kodak cov kev tswj xim. Cov kev tswj xim txawv nyias muaj peev xim txawv rau cov khoom siv thiab muaj lawv qhov kev txawj ntse, cov tuam txhab lag luam yuav tsum xub txiav txim siab uas yuav tsum muaj cov xim zoo sib xws rau kev xaiv.
Secondly, nws yog ib qhov tsim nyog los txiav txim rau tus kheej-describing cov ntaub ntawv nyob rau hauv cov kev tswj xim xim thiab seb puas yuav txhawb cov creation ntawm cov lus piav qhia nyob rau hauv qhib qhov system; nyob rau hauv cov ntaub ntawv ntawm lub kaw lus kaw tseg, lub khw yuav tsum tsim ib cov ntaub ntawv piav qhia, yog li ntawd nws yog ib qhov tsim nyog los txiav txim seb nws tuaj yeem txheem cov ntaub ntawv piav qhia. Tus nqi yuav tsum tau. Lub system yuav tsum muab coj los sib piv thiab sim ua raws li lub tuam txhab tus kheej qhov teeb meem, xws li qhov kev ntseeg muaj peev xwm, cov cuab yeej pab txhawb, kev soj ntsuam, kev sib haum xeeb thiab kev yooj yim ntawm kev siv. Cov ntaub ntawv sau tib xim tuaj yeem siv rau kev soj ntsuam los soj ntsuam lub hauv paus. Hauv kev khiav hauj lwm ib puag ncig, cov nyhuv uas hloov qhov qub tau txais.
Kev tswj cov xim zoo yog qhov guarantee ntawm tag nrho cov qauv zoo, tab sis qhov kawg khoom yog tiav los ntawm number case. Ua ib qho ntawm tsib lub ntsiab lus ntawm kev luam ntawv, number case muaj ib qho tseem ceeb ntawm txoj kev luam ntawv thiab kev zoo. Kev siv thiab tsim nyog siv thiab blending cov inks yog tus yuam sij rau kev ua kom muaj xim zoo nkauj.
Duav teeb meem siv
Cov cwj pwm thiab cov khoom ntawm tus cwj pwm: Cov dej hauv cov kua ua tau ua los ntawm cov dej-soluble resins, cov pigments, cov tshuaj yaj yeeb thiab cov tshuaj ntxiv. Hawj yog nyob ntawm qhov xim ntawm cov pigment, thiab cov pigment feem ntau yuav tsum tau muaj xim daj, lub haum tinting zog thiab zais fais fab, zoo tiv thaiv thiab ib theem ntawm dispersion. Yuav kom tau zoo ntawm cov ntawv luam tawm ntawm tus cwj pwm, ntau tus cwj pwm (additives) muaj ntau zaus siv los kho qhov fluidity, dryness thiab viscosity ntawm tus cwj pwm raws li cov xwm txheej sib txawv. Muaj ntau ntau yam uas txiav txim seb qhov zoo ntawm tus cwj pwm, thiab kev siv tsis zoo yuav coj tau teeb meem zoo. Thaum nriav thiab siv, koj yuav tsum faj seeb rau kev tsom xam, txiav txim siab nws tus tswv thiab cov khoom siv, thiab kho kom haum raws li qhov teeb meem los xyuas kom meej nws cov ntawv sau ua zoo. .
Hauv kev luam ntawv, tus number case muaj ib qho viscosity uas yog ib qho tsim nyog rau kev tswj hwm txoj kev hloov thiab hloov xaib. Vim li no, qhov uas ua rau high-grade mem kua nyeem yog feem ntau tswj li ntawm 20 ± 5 vib nas this, thiab qhov txawv ntawm viscosity ua rau qhov txawv ntawm qhov xim ntawm cov luam ntawv. Hauv cov txheej txheem ntau lawm, nyob ntawm seb cov khoom siv thiab qhov ntsuas kub npaum li cas, tus nqi pauv ntawm cov cwj mem ntawm lub tshuab yuav raug kho lossis tswj tau ntawm 8.0 thiab 9.5.
Loj blending blending: Ink blending tsuas yog hais txog cov xim blending ntawm inks. Hauv cov ntawv luam ntawm cov khoom ntim khoom, cov xim ntawm cov cwj mem zas yog siv rau qhov xim xim ntawm qhov chaw xim, ua tiav cov teebmeem kev ua haujlwm thiab kev tiv thaiv.
Qhov sib txawv ntawm cov xim no tsis tuaj yeem ua ntau tshaj plaub lub xim ntsuab, daj, dub, thiab dub. Feem ntau lawv tsis siv ncaj qha. Nws yog qhov tsim nyog rau cov kws kho cov cuab yeej los kho tus thawj tus cwj pwm raws li cov kev mob. .
Cov xim xim ntawm tus cwj mem piv yog los ntawm txoj cai ntawm kev sib rho xim, qhov ntawd yog, txhua yam xim muaj peev xwm yuav zoo los ntawm kev siv ntau feem ntawm peb thawj xim, thiab xaiv qhov peb theem pib ntawm Hawj, ci ntsa iab thiab saturation. Hauv cov xim sib piv, tus cwj pwm txuam yuav tsum raug txiav txim siab raws li qhov tseeb cov txheej txheem, cov thickness ntawm tus number case, txheej txheem substrate, thiab cov zoo li, thiab cov hawj, gloss, tinting zog, zais fais fab thiab cov zoo li tus cwj mem nws tus kheej raug suav hais tias yog.
Xim txoj kev txuam
Kev soj ntsuam ntawm cov xim thawj: Toning yog ua nyob rau xim ntawm tus thawj. Yuav kom txo tau qhov muag tsis pom ntawm xim, cov xim thawj xim yuav tsum tau ua ntej yuav tsum tau soj ntsuam los txiav txim siab txog cov hawj thiab qhov ntsuas ntawm tus qauv number case. Qhov kev ntsuam xyuas ntawm phau ntawv yog ib qho kev sib txuam ntawm cov xim ntsuas thiab tib neeg lub qhov muag colorimetry. Nws yog qhov yooj yim thiab cov tswv yim los txiav txim qhov piv ntawm peb hom xim inks los ntawm luam ntawv chromatography, thiab peb thawj xim xim thiab cov cwj mem kua dawb dawb xam los ntawm cov feem pua ntawm cov thawj xim thaj chaw cim rau hauv chromatogram.
Xim txuam: Raws li qhov sib piv, tus nqi me me ntawm thawj hom xim muaj xim thawj zaug uas yog siv rau kev xyaw. Nco ntsoov tias tus zauv muaj xim piv nrog cov xim thawj. Thaum ob lub xim zoo nkauj, tus lej muab kho tau muab piv rau ntawm cov ntawv xov xwm, thiab rov qab ua dua kom txog thaum ob xim zoo ib yam. Thaum colorimetric, tus number case yuav tsum sib npaug sib npaug, thiab thev tus number case txheej, zoo dua. Yuav kom ntseeg tau tias qhov tseeb ntawm cov Hawj ntawm cov qauv xim, daim ntawv yuav tsum yog tib yam li daim ntawv siv luam ntawv. Qhov hloov ntawm kev ci ntsa iab thiab kev tuaj yeem yog tau los ntawm kev muab cov dawb dawb number case thiab dub number case. Thaum cov xim dawb thiab dub ntxiv yuav tsum tau ntxiv, tshwj xeeb yuav tsum them rau qhov tseeb ntawm kev nyhav.
Tom qab tus cwj mem muab faib rau tus neeg tau txais kev pabcuam, nws yuav muab cov cwj mem npawb los faib rau hauv ib feem. Tus nqi ntawm tus cwj pwm uas siv rau hauv ib qho kev ua haujlwm feem ntau yog txiav txim siab los ntawm hom ntawv, qhov chaw duab, tus naj npawb ntawm cov luam tawm, thiab ntau npaum li cas, thiab yog ua tiav ntawm ib qho qauv uas tsawg los tsawg dua.
Cov ntaub ntawv: Thaum qhov kev npaj tiav, qhov piv ntawm cov xim muaj ntau yam xim siv rau cov lej hloov, roj, cov roj ntsha, hom kua, ntau, cov chaw tsim khoom thiab lwm cov ntaub ntawv yuav muab teev rau hauv kev nthuav dav, uas yog yooj yim rau yav tom ntej ntawm kev muab faib.
Lwm cov kev xyuam xim: Thaum ntsuas cov thawj thiab xim kabmob, nws yog qhov zoo tshaj plaws los nqa lub teeb pom kev los yog lub teeb qhov chaw nyob ze rau nruab hnub, thiab xyuam xim rau xim xim tom qab ziab, los txo qhov kev ua yuam kev pom. Sim siv cov xim uas ze ze ntawm cov xim uas yog thawj xim lossis lwm yam xim. Yog tias xim ntau dhau lawm, qhov ci thiab qhov teeb meem yuav loj tuaj, uas yuav cuam tshuam rau cov nyhuv luam ntawv. Yog li, tsawg dua cov naj npawb hauv cov xim sib txawv, nws yuav zoo dua, nws yog qhov zoo tshaj plaws los xaiv tib lub khw muag khoom kabmob.
Thaum muab qhab nia, nws yuav tsum to taub txhua hnub kev luam ntawv thiab luam tawm siab ntawm cov cuab yeej ntawm lub hoobkas, thiab tswj cov xauv npab ntawm tus cwj pwm. Txawv luam ntawv ntau thiab cov pressures yuav tsim ntau ntxoov cov ntawv luam tawm. Vim li no, cov phom sij uas tau faib rau qis qis dua yuav tsum rov tshawb xyuas nrog cov keeb kwm tom qab lub zuag hluav taws xob tig mus rau qhov qub ceev kom tsis txhob chromatic aberration thiab pov tseg.
Tom qab tus cwj mem xa tawm, yog pom tias cov qauv xim sau rau ntawm lub tshuab yog yuam kev nrog tus thawj, nws yuav tsum tau kho thaum lub sijhawm. Thaum hloov xim, tus cwj mem kua number case thiab cov quav hauv plawv yuav tsum tau ntxuav kom tsis txhob muaj xim hloov los ntawm qhov tsis huv. Rau qhov chaw xim kua cuav tom qab luam ntawv, nws tseem yuav tau kho raws li tus hawj ntawm tus ntawv sau tshiab, tab sis qhov xim txias heev feem ntau grey, tshwj xeeb tshaj yog cov seem uas muaj retrieved ntawm tus ciav ciav, uas tau muaj emulsified los yog cov ntawv luam tau hloov .
