Yuav Ua Li Cas Chocolate Boxes Rau Khoom Plig prepress platemaking RGB cov ntaub ntawv ua

 

Tam sim no, kev ua cov duab cov ntaub ntawv feem ntau tsis xav txog cov kev xav tau ntsig txog kev luam ntawv, ncaj qha hloov los ntawm RGB rau CMYK. Txhawm rau tsim cov ntawv luam tawm zoo los ntawm kev pom kev tshaj lij, nws yog qhov tsim nyog los ua qauv RGB cov ntaub ntawv ua haujlwm thiab siv CMYK cov ntaub ntawv hloov pauv txoj kev tsim nyog tshaj plaws rau kev luam ntawv.

 

Yav dhau los phaj-ua tshuab yog ib hom kev sib txuas mus ntev ntawm kev siv tshuab. Piv txwv li, txhawm rau tsim qhov ci ntsa iab ntawm daim tawv nqaij, M15 feem pua ​​​​thiab Y20 feem pua ​​​​yog muab rau cov tawv nqaij Nyij Pooj, thiab M20 feem pua ​​​​rau cov neeg European thiab Asmeskas, thiab qhov dawb ntawm lub qhov muag raug coj tawm ntawm lub vas. Txawm niaj hnub no, thaum cov txheej txheem tau digitized, nws yog ib qho tsim nyog yuav tsum ua kom zoo siv cov thev naus laus zis hauv yav dhau los kom raug RGB-CMYK cov ntaub ntawv hloov dua siab tshiab kom ua tiav cov kev cai luam ntawv zoo.

 

1.RGB cov ntaub ntawv ua

Lub npe hu ua RGB cov ntaub ntawv ua haujlwm yog hais txog kev siv RGB cov ntaub ntawv raws li cov ntaub ntawv ntawm cov neeg ua haujlwm prepress, thiab hloov thiab kho cov ntaub ntawv kom tau raws li cov kev cai ntawm CMYK luam ntawv cov ntaub ntawv. Tshwj xeeb, nws suav nrog:

(1) CMYK hloov dua siab tshiab ua haujlwm ntawm RGB cov ntaub ntawv;

 

(2) kev ua haujlwm calibration (cov koob yees duab digital, cov lus qhia, cov khoom tso tawm, cov khoom siv cia, thiab lwm yam);

 

(3) cov duab ua haujlwm (xim kho, duab synthesis, tone transformation, duab kho, thiab lwm yam);

 

(4) Kev tswj xim (xws li twv thiab txiav txim cov txiaj ntsig tau raws li cov ntaub ntawv digital, thiab lwm yam), thiab lwm yam.

 

Txhawm rau ua haujlwm zoo ntawm kev ua haujlwm RGB, nws yog ib qho tsim nyog rau cov kws yees duab, cov tsim qauv, cov tuam txhab phaj, thiab lwm yam kom paub qhov txawv ntawm lawv lub luag haujlwm, raws li kev tsim cov ntaub ntawv ua haujlwm RGB. Nws yog ib qho tseem ceeb kom paub meej txog cov cai ntawm kev hloov pauv.

 

Lub tuam txhab prepress yuav tsum teeb tsa ib chav los tshuaj xyuas tus lej RGB txawv teb chaws kom cov ntaub ntawv tsim nyog tuaj yeem xa mus rau cov txheej txheem tom ntej raws li xav tau.

 

2. Qhov tsim nyog ntawm RGB workflow

Txhawm rau kom paub txog kev ua haujlwm ntawm RGB cov ntaub ntawv, nws yog ib qho tsim nyog los tsim kom muaj kev ua haujlwm sib raug rau cov ntaub ntawv RGB duab. Nrog rau tus naj npawb ntawm RGB qhov qub hauv cov koob yees duab digital, qhov kev xav tau no yuav tsum tau ua tiav. Los ntawm kev ua tiav ntawm RGB kev ua haujlwm, lub luag haujlwm thiab kev ua haujlwm ntawm cov kws yees duab thiab cov neeg tsim qauv tuaj yeem txo qis, thiab qhov tshwm sim ntawm qhov xwm txheej zoo tuaj yeem txo. Tsis tas li ntawd, lub sij hawm xa tuaj tuaj yeem luv luv thiab tus nqi yuav raug txo. Yog tias cov duab cov ntaub ntawv tau ua rau hauv cov ntaub ntawv, nws tuaj yeem tsis tsuas yog txhim kho kev ua haujlwm ntawm kev ua haujlwm, tab sis kuj tseem siv cov ntaub ntawv duab ob zaug.

3. Benchmark formulation ntawm RGB workflow

Txhawm rau tsim kom muaj kev ua haujlwm RGB, kev sib koom tes ntawm tus tswv haujlwm uas muab cov thawj coj yog xav tau, yog li nws yog ib qho tseem ceeb kom tau txais cov qauv ntsuas. Nov yog cov piv txwv tshwj xeeb.

 

(1) Yuav tsum muaj rau cov kws yees duab

* Siv photoshop6.0 lossis siab dua;

 

* Cov zaub yuav tsum tau calibrated;

 

* Tsis txhob hloov cov ntaub ntawv RGB duab rau CMYK cov ntaub ntawv;

 

* Yog tias koj xav tau hloov xim loj, thov xa mus rau lub tuam txhab prepress hauv RAW cov ntaub ntawv hom;

 

* Teem cov duab daws teeb meem rau 350dpi;

 

* Muab cov ntaub ntawv ntawm cov ntaub ntawv cov ntsiab lus (los ntawm kws yees duab, software siv, xim chaw, kev daws teeb meem, txawm tias nws yog sharpened, thiab lwm yam);

 

* Thaum luam ntawv loj yog A4, lub koob yees duab yees duab nrog ntau dua 6 lab dluab yog siv;

 

* Rau cov ntawv luam tawm zoo xws li kev yees duab ntawm daim tawv nqaij, lub koob yees duab yees duab nrog ntau dua 12 lab cov duab yuav tsum tau ua.

 

(2) Cov kev xav tau rau cov neeg tsim qauv

* Cov zaub yuav tsum tau calibrated;

 

* Tsis txhob hloov cov ntaub ntawv RGB duab rau CMYK cov ntaub ntawv;

 

* Kev kho xim thiab kev tswj xim ntawm cov duab yog ua los ntawm lub tuam txhab prepress;

 

* Cov qauv tsim ntawm kev sib koom ua ke thiab cov qauv loj yog xa mus rau lub tuam txhab prepress.

 

4. CMYK hloov dua siab tshiab los ntawm kev xav

Txhawm rau ua kom CMYK hloov dua siab tshiab, koj yuav tsum hloov xim Chaw ua los ntawm cov ntawv nyeem. Kev ua haujlwm hloov dua siab tshiab nws tus kheej yog qhov yooj yim heev, thiab yog Ameslikas "yuav ua li cas hloov kom tau txais cov khoom zoo kom rov tsim cov xim uas xav tau", tab sis nws yog qhov teeb meem kev tshaj lij. Txhawm rau tsim cov xim nyob ze rau RGB cov duab, kev hloov kho qhov ceev thiab qib yuav tsum tau ua, thiab kev txawj ntse tau ua nyob rau hauv qhov chaw xim CMYK kom tau txais cov xim xav tau. Piv txwv ntawm cov ntsiab lus tseem ceeb rau kev ua tiav cov xim zoo nkauj yog muab hauv qab no

 

(1) Thaum kho cov cim ntawm cov phaj dub, kev ua haujlwm hloov pauv tau ua tiav (ua kom tshem tau cov phaj dub ntawv luam tawm, kev hloov pauv grey, ze rau thawj xim, nrhiav cov ntsiab lus, thiab lwm yam);

 

(2) Vim tias cov ntawv luam ntawv qee zaum tsis raug, yog li nws yog qhov tsim nyog rau kev ua cov cuab yeej (kom cov xim tom qab tsis pom tseeb). Qhov thib ob taw tes nyob rau hauv cov duab cov ntaub ntawv los yog keeb kwm yav dhau muaj txheej txheej ntawm lub sij hawm, los tiv thaiv lub phaj yog tsis pub kom muaj ib tug heev nyuaj, yuav tsum tau kev txawj ntse technology. Cov hauj lwm zoo li no tuaj yeem hais tau tias yog txoj haujlwm tshaj lij.
