Softcover Educational Books ob-xim phau ntawv luam ntawv tsim thev naus laus zis tseem ceeb thiab ntau txoj hauv kev

Ob-xim luam ntawv tsim, yooj yim hais lus, hais txog ib yam duab los ntawm cov xim sib cais ua tshuab, siv kev sib xyaw ua ke ntawm ob xim sib txawv ntawm tus cwj mem, rov tsim cov nyhuv qub ntawm cov txheej txheem. Feem ntau, C, M, Y, K plaub-xim luam ntawv daim hlau, dub (K) phaj thiab lwm yam peb-xim (C, M, Y) luam ntawv daim hlau txhua yam ua ke, vim tias cov phaj dub hauv cov xim tsaus nti ntawm cov duab theem cov ntaub ntawv faib tawm muaj zog, tuaj yeem txhim kho qhov sib piv ntawm cov duab suab. Nyob rau hauv lub suab nrov, cov ntaub ntawv lub suab dub tsis muaj zog, thiab cov xim txheej ntawm C, M thiab Y muaj zog dua. Nyob rau hauv txoj kev no, txheej txheej ntawm cov duab tuaj yeem hloov pauv nrog cov xim hloov, thiab nws yooj yim dua los tsim cov xim qub txheej thiab cov ntaub ntawv suab ntawm cov duab. Kev sib xyaw ua ke ntawm C, M thiab Y, txawm hais tias cov xim ntau yog loj hauv lub suab nrov, tab sis tsis muaj cov duab txheej hauv lub suab tsaus, ua rau cov duab tonal sib txawv me me, nyuaj rau kev tsim cov duab qub qub. Yog li ntawd, ob-xim luam ntawv tsim feem ntau yog hais txog kev sib xyaw ntawm cov xim dub thiab lwm yam xim.

Tus yuam sij rau ob-xim luam ntawv tsim yog kom ua tiav cov xim uas xav tau los ntawm kev hloov cov kev sib raug zoo ntawm ob-xim ua ke raws li kev tiv thaiv tag nrho cov thawj theem thiab cov suab lus ntawm cov duab, thiab cov cuab yeej zoo tshaj plaws kom ua tiav cov xim no yog ob-tone hauv Photo-shop duab ua software. Ob lub suab yog kho qhov nkhaus ntawm ob lub xim sib txawv kom ua tiav cov duab xav tau los ntawm cov duab kos duab. Nyob rau hauv lwm yam lus, ob-xim luam ntawv tsim tsis yog ib tug ncaj qha txo ntawm C, M, Y thiab K (ob channel yog rho tawm thiab ob txoj kev yog khaws cia), tab sis raws li cov qauv qauv ntawm greyscale duab nws tus kheej. Siv cov cuab yeej Curve los kho ob xim thiab rov ua cov xim ntawm ntau qib. [tom ntej]

Txoj hauv kev yog:

1. Xyuas kom meej tias cov duab qub nyob hauv hom RGB. Ntau dua li CMYK hom (Vim RGB hom yog hom xim raws li cov qauv kho qhov muag, thiab CMYK hom yog txiav txim siab los ntawm kev nqus cov cwj mem ntawm daim ntawv, yog li RGB hom muaj xim ntau dua li hom CMYK. RGB hom tuaj yeem sawv cev ntau xim. Piv nrog rau CMYK hom, RGB hom tuaj yeem cuam tshuam cov ntaub ntawv ntau dua ntawm cov duab hierarchy thiab lub suab.

2. Tom qab ntawd hloov RGB hom rau Lab hom, tshem tawm ob lub xim raws a thiab b, thiab khaws cia tsuas yog L brightness channel. Tom qab ntawd, L luminance channel hom hloov mus rau Grayscale greyscale hom (Vim tias Lab hom muaj cov yam ntxwv zoo, nws muaj ntau yam xim, ua rau qhov tsis txaus ntawm RGB thiab CMYK xim hom. los ntawm hom Lab tuaj yeem khaws cov ntaub ntawv cov kauj ruam ntawm cov duab qub ntau dua li cov hom grey ncaj qha hloov los ntawm RGB thiab CMYK).

3. Siv cov cuab yeej ob lub suab rau ob-xim tsim ntawm cov duab grayscale. Nyob rau hauv tus txheej txheem ntawm kev siv ob lub suab, koj tuaj yeem ua tiav qhov zoo tagnrho ob-xim nyhuv los ntawm kev kho ob-xim nkhaus raws li koj tus kheej tsim xav tau. Qhov ob-xim tsim yog ces khaws cia ua ib cov ntaub ntawv PhotoshopEPS. Nyob rau hauv txoj kev no, txoj haujlwm sib cais xim ntawm ob-xim luam ntawv tsim duab tiav, vim tias ob-xim luam ntawv tsim cov txheej txheem nyob rau hauv ob-xim tsim ntawm daim duab. [tom ntej]

Muaj qee tus neeg tsim duab kos duab vim tsis muaj kev nkag siab txog cov ntsiab lus ntawm kev luam ntawv thev naus laus zis thiab kev ua haujlwm ntawm Photoshop software tsis txawj ntse. Yog li ntawd, txoj kev tsis ncaj ncees yog feem ntau siv rau ob-xim luam ntawv tsim. Feem ntau muaj ob hom hauv qab no:

Ib qho yog xaiv cov duab ncaj qha ntawm ob qhov sib txuas hauv plaub xim C, M, Y thiab K, lossis xaiv ob txoj kab uas muaj cov duab nplua nuj kom tso tawm phaj. Txoj kev no tsuas yog siv cov ntaub ntawv hauv cheeb tsam ntawm cov duab ntawm tus nqi ntawm cov ntaub ntawv theem ntawm lwm cov channel, uas yuav ua rau muaj kev cuam tshuam ntawm cov duab.

Qhov thib ob, txhawm rau txhim kho cov lus qhia kauj ruam ntawm qee cov channel, CMYK hom ntawm daim duab yog thawj zaug hloov mus rau Grayscale greyscale hom, uas yog, plaub-xim channel tau muab tso rau hauv ib qho monochrome channel, thiab tom qab ntawd rov qab mus rau CMYK plaub- xim hom. Thaum kawg, cov duab cov khoom ntawm ob txoj kev sib raug tau raug xaiv los ua cov ntawv phaj. Piv nrog rau txoj kev 1, txawm hais tias theem ntawm cov duab hauv qee cov channel tau txhim kho, cov ntaub ntawv theem ntawm lwm cov channel tseem poob ntau dua, uas ua rau cov duab distortion.

Cov ntsiab lus tseem ceeb ntawm kev tsim qauv tsim yog tsim los ntawm cov duab, cov ntawv vector, cov kab zoo nkauj thiab cov xim thaiv, uas yuav tsum tau ua kom cov duab tsim ob xim yuav tsum tau ua ke nrog nws cov kab lus sib xws, thiab xim ntawm cov ntawv nyeem, cov kab zoo nkauj thiab cov xim thaiv hauv. pawg software yog txhais los ntawm nws tus kheej palette, yog li tus yuam sij rau ob-xim luam ntawv tsim txuj ci yog:

Ob-xim Photoshop dluab imported nyob rau hauv pab pawg neeg software (xws li Pagemaker, Freehand, thiab lwm yam) yuav tsum tau siv raws li ob-xim Photoshop dluab nyob rau hauv pab pawg neeg software. Piv txwv li: Ib daim duab tsim nrog Lub Tsev Muag Khoom ob lub suab muaj cov xim xim dub thiab PANTONE1915, thiab thaum koj muab cov duab ntawd tso rau hauv pab pawg ntawm Pagemaker, Ob qhov xim xim dub thiab PANTONE1915 tau cia li coj mus rau hauv cov duab hauv Pagemaker's xim palette. Thaum txhais cov ntawv, kab thiab thaiv xim hauv Pagemaker, tsuas yog dub thiab PANTONE1915 yuav tsum tau siv. Nyob rau hauv no txoj kev los xyuas kom meej cov phau ntawv lig tso zis phaj rau ob - xim.
