Ua ntej, lub tswvyim ntawm nruab nrab gray tshuav nyiaj li cas
Cov ntawv luam ntawm cov ntawv luam tawm yog xim kho kom zoo nkauj, txo lub suab, kho kom zoo nkauj, thiab kev daws teeb meem. Qhov kev sib txuas lus yog tias cov xim yog cais tawm ntawm ci ntsa iab, qhov xim yog qhov peb-xim, qhov nruab nrab ntawm qhov nruab nrab yog qhov xim xim tha xim, qhov nruab nrab ntawm cov xim ntawm Y, M, thiab C, thiab peb lub zog ntawm cov xim (hawj, saturation, ci ntsa iab) Hv / c txhais tau hais tias qhov nruab nrab ntawm qhov nruab nrab tsis muaj teebmeem, tsis tuaj yeem, tsuas yog qhov ci ntawm ib sab.
Peb paub hais tias peb lub ntsiab xim R, G, thiab B ntawm cov teeb xim hloov mus rau lub tshav pob, thiab peb thawj xim Y, M, thiab C ntawm cov khoom xim yog hloov mus rau qhov chaw dub. Ntxiv mus, plaub-xim luam tsuas yog muaj ob qho kev txwv: ib qho yog siv plaub xim ntawm Y, M, C, thiab K; lwm tus yog tias cov khaubncaws sab nraud povtseg ntawm txhua daim ntawv sib npaug zos.
Qhov nruab nrab ntawm cov xim tsis txaus siab yog hais txog Y, M, thiab C. Lawv nqus cov R, G, thiab B xim sib npaug sib npaug, thiab tsuas hloov qhov ci ntsa iab tsis hloov hauv hawj thiab chroma.
Thaum peb lub ntsiab Y, M, thiab C ntawm cov ntaub ntawv xim yog overprinted nyob rau hauv ib qho piv txwv uas tsim nyog, qhov nruab nrab nruab nrab grey yuav ua tiav reproduced. Tom qab ntawd, peb lub ntsiab xim ntawm Y, M, thiab C tau hais tias kom ncav cuag ib qho nruab nrab ntawm qhov nruab nrab ntawm grey. Qhov sib npaug ntawm cov xim ntawm peb lub ntsiab uas ua tiav qhov sib npaug ntawm qhov grey yog hu ua qhov sib npaug nruab nrab ntawm qhov nruab nrab gray.
Qhov thib ob, hais txog qhov tseem ceeb ntawm qhov nruab nrab ntawm qhov nruab nrab ntawm grey
1. Ua tib zoo muab daim phiaj ntawm daim tseem.
2. Thaum lub sij hawm ntawm phaj ua thiab luam ntawv, qhov nruab nrab ntawm qhov nruab nrab ntawm qhov nruab nrab ntawm qhov nruab nrab yog siv los ntsuas seb qhov sib txawv ntawm peb hom thawj xim ntawm kev cais thiab luam tawm yog tsim nyog.
Qhov peb, qhov xim tshem tawm tom qab thiab tsis tshuav qhov sib npaug grey
1. Lub tswv yim ntawm keeb kwm xim tshem tawm, qhov sib txawv xim tom qab tshem tawm (UCR) hais txog qhov kev tshem tawm ntawm ib feem ntawm cov xim nruab nrab ntawm peb thawj xim ntawm Y, M, C, uas yog, yuav luag dub qab los ntawm cov khoom loj ntawm peb lub ntsiab Y, M, C. Xim thiab hloov nrog tus cwj mem kua dub.
Piv txwv, yog muaj xim Y, M, thiab C, cheeb tsam ntawm Y dot yog 80%, thaj tsam ntawm M dot yog 80%, thiab thaj tsam ntawm C dot yog 100% (hauv lub tshav pob). Yog tias nws muaj qhov nruab nrab ntawm qhov nruab nrab ntawm qhov nruab nrab, 80% Y thiab 80% ntawm M kuj sib tshim nrog 90% ntawm C kom muab tus cwj mem dub piv rau 90% dot thaj tsam, ces: C = 80% Y + 80% M + 100% C = 80% Y + 80% M + 90% C + 10% C = 90% K + 10% C
2. Qhov tseem ceeb ntawm kev tshem tawm hauv av xim, 1 ua rau cov ntawv pov thawj: feem ntau, nws yog siv nyob rau hauv lub suab tsaus nti. Yog hais tias peb lub ntsiab Y, M, thiab C raug luam tawm hauv cheeb tsam tsaus ntuj, qhov cheeb tsam dot yog feem ntau siab. Hauv high-speed ntau xim xim, Yooj yim tsim teeb meem. Yog tias lub hauv paus xim raug tshem tawm, tus nqi ntawm tus cwj mem yog txo kom tsawg, thiab qhov ua kom zoo dua tuaj. 2 Ua kom tswj tau qhov nruab nrab ntawm qhov nruab nrab ntawm grey tsis pub dhau thaum luam ntawv. 3 yog ib qho zoo rau kev ziab ntawm tus cwj pwm, txo cov nqi ntawm cov thawj ntawm peb hom xim ntxiv ntawm Y, M, C. 4 Vim tias tus nqi Y, M, C xim muab txo, tus nqi ntawm cov xim dub ntxiv , li no txo tus nqi, thiab tus nqi ntawm cov cwj mem dub yog pheej yig. 5 Tom qab siv tshuab luam tawm high-speed ntau xim, qhov teeb meem loj tshaj rau kev ceev thiab kev txhim kho cov tshuab luam ntawv high-speed yog numbering drying teeb meem, uas txhais tau hais tias tus lej ntawm number case ziab yuav ncaj qha rau kev ceev thiab zoo ntawm high- ceev tej xim tshuab luam ntawv. Kev daws qhov teeb meem yog siv ntau yam, xws li hloov cov kab kos thiab tus qauv ntawm tus cwj pwm, kev txhim kho txoj kev ziab ntawm kev luam ntawv, thiab kev txhim kho cov txheej txheem, kev txhim kho cov concentration thiab gloss ntawm tus cwj mem dub, thiab txo Y, M, thiab C thawj xim muaj xim nyob hauv cov xim xim daj. Tus lej ntawm tus lej ntawm ib sab, uas zoo thim ntu number case los ua kom lub ziab, uas yog lub hauv paus ua rau UCR hauv kev luam xim.
3. Cov ntsiab lus ceeb toom thaum tshem cov xim av
1 Tom qab xim xim tshem tawm feem ntau ua haujlwm hauv nruab nrab, tsaus nti-kho tsis nruab nrab grey thiab ze-nruab nrab grey chaw.
2 Ua tus tswj cov nqi rho tawm.
3 tus tswj kev tswj ntawm kev tshem tawm taw tes, uas yog los tshem tawm cov uas tswj.
