1. Kho cov duab ntawm lub tshuab luam tawm
Thaum ua cov ntaub ntawv pov thawj, koj yuav tsum tau kho cov linearity ntawm lub tshuab luam ntawv. Thaum lub tshuab luam ntawv siv cov ntawv sib txawv thiab tus cwj pwm, nws cov kab txaij txawv; thaum lub xeev ntawm lub tshuab luam ntawv hloov, cov kev hloov pauv ncaj qha.
Qhov tseeb ntawm linearity tau sai xyuas los ntawm luam gray teev. Qhov teeb meem tseem ceeb tshaj plaws hauv kev tswj ncaj qha yog los xyuas kom meej tias tsis muaj cov xim pob ib nrab tshwm sim, uas yog, kom tsis txhob muaj suab nrov sib txawv los ntawm kev sib txawv hauv cov xim sib txawv. Nruab nrab lossis qaim laus yog ib qho xim rau lwm qhov xim, yog li ntawd kev hloov kho yav tom ntej tseem nyuaj ua.
2. Kev sib piv ntawm luam ICC thiab lub tshuab luam ntawv ICC
Cov xim gamut ntawm lub tshuab luam ntawv ICC yog qhov loj tshaj cov xim gamut ntawm luam tawm ICC. Yog hais tias cov xim gamut ntawm lub tshuab luam ntawv me dua cov duab xim gamut, cov nyhuv proofing yuav ntiav. Thaum muaj cov duab nyob hauv cov xim thiab cov xim dub ntawm tib xim, lub tshuab luam ntawv tsis zoo nrog rau xim. Thaum twg daim duab nrog daim duab, qhov tsaus nti toner tsis txaus, thiab qhov txho grey; thaum siv cov xim dub, daim duab no kuj sib sib zog nqus, tej zaum txawm muab tshuaj txhuam. Xws li lub tshuab luam ntawv ICC tau hloov me ntsis, thiab cov xim xim txuam yog qhov tseeb tsis zoo thiab yuav tsum tau muab redone.
Muaj ntau ntau yam rau cov xim me me ntawm cov ntawv ICC, feem ntau yog vim li cas ntawm kev luam ntawv thiab kua number case, daim ntawv yog ib qho dhau heev lawm, tus cwj pwm absorption kev kawm tsis zoo, tus number case yog impure, qhov zoo ntawm tus tso cai yog poob, thiab lwm yam., uas yuav ua rau kom txo tau ntawm cov xim luam ntawv gamut.
Yog xav paub seb puas muaj kev dhia hauv cov ntawv ICC thiab cov pov thawj ICC, yog tias muaj kev dhia, qhov xim ntawm qhov zoo li no tsis tuaj yeem simulated txhua zaus. Yog vim li cas rau luam ICC xim hopping yog vim yog qhov nce ntawm dots printing; yog vim li cas rau lub tshuab luam ntawv ICC dhia mas yog vim lub linearity ntawm lub tshuab luam ntawv tsis ua tiav zoo, thiab nws yog tsim nyog los kho lub linearity ntawm lub tshuab luam ntawv, kho los yog redo lub ICC.
Xim gamut sib piv ntawm luam ICC thiab lub tshuab luam ntawv ICC nyob rau hauv ProfileMaker 5. Nws tuaj yeem pom tias nyob hauv qhov chaw tsaus nti (L nqi yog 23), cov xim xim gamut tsis tuaj yeem muaj cov xim luam yeeb gamut, thiab cov xim tsis muaj xim hauv cov xim gamut simulated los ntawm qhov pov thawj. Muaj ob txoj hau kev rau qhov no. Ib qho yog tias lub hom phiaj xim tsis tau sau kom zoo, thiab cov xim cam yog loj; lwm tus yog tias cov ntawv luam tawm gamut me me thiab lub tshuab luam ntawv ICC cov ntaub ntawv xav tau rov tsim.
Tsis tas li ntawd, nyob rau hauv daim duab, nws yuav pom tau hais tias ntug ntawm lub luam yeeb xim gamut yog tsis tus, thiab muaj ib tug dhia. Yog tias cov ntaub ntawv pov thawj muaj kev hloov kho raws li qhov chaw luam tawm, ntau xim tsis pub sim.
3. Siv cov software sab nraud los hloov cov ntaub ntawv ICC
Ntau lub sij hawm peb yuav tsum tau kho cov ICC los ntawm kev pabcuam thib peb. Muaj ntau ntau qhov kev tsim kho rau ICC, tab sis lub tswv yim tseem ceeb ntawm tsev kawm ntawv cov xim zoo ib yam. Cov nram qab no yuav siv ProfileMaker5 ua piv txwv qhia txog cov theem pib ntawm cov xim kho.
(1) Kho cov xim keeb kwm yav dhau. Raws li lub tuam txhab qhov teeb meem no, nws yog txiav txim siab seb xim keeb kwm xav kom muab khaws cia, thiab xim ntawm cov xim tom qab tuaj yeem kho raws li qhov xwm txheej tiag tiag.
(2) Kho cov nyiaj tshev grey siv cov cuab tam nyiaj seem. Cov kev hloov kho tau tuaj yeem tshawb xyuas tsis tau nruab nrab ntawm qhov nruab nrab ntawm qhov nruab nrab ntawm grey (ceeb toom: qhov hloov hauv qhov ntsuas grey yuav cuam tshuam rau tag nrho cov xim, thiab kev hloov tsis tsim loj heev).
(3) Kho cov xim cam ntawm CMYK cov xim yooj yim uas siv cov cuab yeej tawm, tshwj xeeb tshaj yog cov kev kho ntawm lub Monochrome K. Tshem nyiaj rau qhov hloov ntawm grey tshuav nyiaj thaum txoj kev hloov kho.
(4) Kho cov xim ob qib C + M, C + Y, Y + M, C + K, Y + K, M + K siv cov cuab yeej haum. Qhov tshwj xeeb tshaj yog qhov tsaus ntuj nti thiab midtone ntawm cov xim.
(5) Xaiv xim xim xim rau CMYK dua. Xaiv xim xim xim rau kev luam ntawv cim. Feem ntau hais lus, ntau ntau xim, qhov zoo dua qhov kev xaiv xaiv. Rau cov hluavtaws nruab nrab ntawm qhov nruab nrab, cov nyhuv ntawm kev xaiv xim xim tsis yog cuab kev, thiab nws yog kho los ntawm gray tshuav nyiaj. Cov nyhuv zoo dua. Rau nruab nrab grey, koj muaj peev xwm nce qhov kev faib ua feem ntawm dub thiab stabilize xim.
(6) Thaum kawg kho lub teeb ci, kev nplua taws, thiab qhov sib txawv ntawm cov duab pov thawj kom ua tau txhua yam xim kho.
(7) Tom qab ua qhov no, ntsuas CMYK kom muaj xim nris nrog lub densitometer los xyuas kom meej tias nws ceev yog ze rau kev luam ntawv.
