Ntau txhiab ntawm cov kev paub luam ntawv! Koj paub ntau npaum li cas?
Plaub-Xim Luam Ntawv

Tsuav peb xim ntawm R + G + B sib sau ua ke ntawm cov xim muaj peev xwm tsim tau. Vim li cas dub? Dub tuaj yeem tsim tawm thaum cov feem sib piv ntawm RGB yog sib npaug, tab sis nws tseem tsis tau tsim ib xim nrog peb inks. Qhov tseeb, hauv cov txheej txheem tsim, dub yog siv ntau, uas yog qhov tseeb vim li cas plaub-xim luam ntawv siv. Lwm lub ntsiab lus yog tias cov dub tsim los ntawm RGB muaj kev nkag siab ntawm kev saib xyuas rau cov dub uas tau sib xyaw nrog tus cwj mem, thaum yav tas los tau ruaj khov dua.
1. Nrog plaub-lub hauv paus ntsiab lus, nws yooj yim dua rau txhua tus kom lees txais. Nws yog sib npaug rau plaub zaj yeeb yaj kiab thaum lub sijhawm tsim tawm, thiab nws tseem sib npaug hauv Photoshop: Cyan, Daj, Dub (k, k). Cov kev hloov pauv uas peb ua rau cov raws thaum peb ua tus txheej txheem cov duab yog qhov hloov pauv tau tiag tiag rau zaj duab xis.
2. Mesh, outlets, cov roj, tiaj tus thiab dai Nets. Mesh: Ib lub square nti, tus naj npawb ntawm cov dots, 175 mesh siv cov luam tawm uas nquag siv, 60 mesh rau 100 mesh rau cov ntawv xov xwm, nyob ntawm daim ntawv. Cov luam ntawv tshwj xeeb muaj cov ntxaij tshwj xeeb, nyob ntawm cov qauv.

1. Cov hom thiab qhov tseeb ntawm daim duab

Kev luam tawm niaj hnub no yog offset luam ntawv (plaub-xim sib txawv), uas yog muab tso rau hauv PS version, tom qab plaub zaug luam tawm los ntawm offset xovxwm, nws yog xim luam ntawv khoom.

Cov luam tawm cov duab yog txawv ntawm lub koos pij tawj zoo tib yam, thiab cov duab yuav tsum yog hom CMYK, tsis yog RGB hom lossis lwm hom qauv. Thaum muaj kev tawm tsam, daim duab yuav hloov mus rau hauv cov dots, uas yog qhov tseeb ntawm cov duab kos, thiab cov neeg muaj qhov tseeb, thiab cov uas feem ntau yog 72dPI RGB hom duab, feem ntau ntawm cov uas tsis tuaj yeem siv rau kev luam ntawv. Daim duab siv tsis tuaj yeem ua kom pom raws li tus qauv, tsis txhob xav tias daim duab tuaj yeem siv rau kev luam tawm, nws yuav tsum tau qhib los ntawm Photoshop, thiab nws yog qhov tseeb tau siv los paub meej tias nws qhov tseeb tiag. Piv txwv li, yog tias qhov kev daws teeb meem ntawm daim duab yog 600 * 600dpi / pixel / nti, ces nws qhov loj tam sim no tuaj yeem loj dua ob npaug ntawm kev siv tsis muaj teeb meem. Yog tias qhov kev daws teeb meem yog 300dpi, tom qab ntawd nws tsuas tuaj yeem ua kom haum qis lossis thawj qhov loj, thiab nws tsis tuaj yeem loj heev. Yog tias qhov kev daws teeb meem ntawm daim duab yog 72 d 72 dpi / pixel / nti, ces nws yuav tsum tau loj dua) kom txog thaum daws tau 300 x 300 dpi, ces nws tuaj yeem siv. (Yog tias koj siv txoj haujlwm no, teeb tsa "redefine pixels" khoom hauv cov duab loj xaiv hauv Photoshop rau tsis muaj.))
Cov duab hom duab yog: Tif, JPG, PCD, PSD, PCX, GIF, BMP, thiab lwm yam

Thib ob, cov xim ntawm daim duab

Hais txog qee cov ntsiab lus tshaj lij xws li overprinting, overrinting, chaw xim, koj tsuas yog muaj qee yam kev txiav txim siab uas yuav tsum tau them siab rau.
1. Hollowing tawm
Yog tias muaj kab ntawm cov ntawv xiav nias rau ntawm cov xim daj, tom qab ntawd ntawm cov duab daj ntawm zaj duab xis, txoj haujlwm ntawm cov ntawv xiav yuav tsum khoob. Qhov thim rov qab yog qhov tseeb rau cov xiav version, txwv tsis pub cov xiav luam ncaj qha rau ntawm daj, thiab cov xim yuav hloov pauv, thiab cov lo lus xiav lub xiav yuav ua ntsuab.
2. Overprinting
Yog tias muaj kab ntawm cov kab dub tau nias rau ntawm lub pob liab liab, tom qab ntawd ntawm cov duab liab ntawm zaj duab xis, txoj haujlwm ntawm cov tsiaj ntawv dub yuav tsum tsis txhob hollowed tawm. Vim tias dub tuaj yeem cuam tshuam ib qho xim, yog tias cov ntsiab lus dub yog hollowed tawm, tshwj xeeb me ntsis hauv kev luam ntawv yuav ua rau muaj kev sib txawv, thiab cov xim dub thiab dawb thiab dawb.
3. Plaub-xim dub
Nov kuj yog ib qho teeb meem ntau ntxiv. Ua ntej xa tawm, nws yog qhov tsim nyog los tshawb xyuas seb cov ntawv dub hauv daim ntawv tshaj tawm, tshwj xeeb tshaj yog cov ntawv luam me me, tsuas yog tsis tshwm sim rau lwm peb-xim versions. Yog tias nws ua li ntawd, qhov zoo ntawm cov khoom luam tawm yuav raug hloov pauv, thiab thaum cov duab RGB tau hloov mus rau CMYK cov duab, cov ntawv dub yuav raug hu hloov pauv plaub-xim dub. Yog tsis muaj lwm yam kev teev tseg, nws yuav tsum tau ua ua ntej zaj duab xis tuaj yeem raug xa tawm.
4. Daim duab yog nyob hauv RGB hom
Thaum twg cov duab yog tso zis hauv RGB hom, lub kaw lus rip yuav cia li hloov nws mus rau CMYK hom zis. Txawm li cas los xij, nws cov xim zoo yuav muaj kev txo qis heev, thiab cov khoom tiav yuav yog lub teeb xim rau hauv cov xim, tsis kaj, thiab cov nyhuv yog qhov tsis zoo heev. Nws yog qhov zoo tshaj plaws los hloov cov duab rau CMYK hom hauv Photoshop, thiab yog tias nws yog cov txheej txheem scenned, nws kuj tseem yuav tsum tau mus kho cov xim xim ua ntej cov duab tuaj yeem siv.
