Hauv kev luam ntawv, kev pov thawj yog ib qho tseem ceeb, uas yog kev sib txuas ntawm cov txheej txheem ua ntej xovxwm thiab luam ntawv. Nws lub luag haujlwm muaj ob lub ntsiab lus: Ua ntej, xyuas cov teeb meem hauv cov txheej txheem ua ntej los mus nrhiav kev ua yuam kev hauv lub sij hawm, ua kev kho, kom tsis txhob ua kom poob ntau dua; thib ob, tswj kev luam ntawv, uas muab cov txheej txheem luam ntawv tso cai rau tus neeg siv pom zoo. Xws li, luam ntawv xav tswj ntau yam kev mob, txheej txheem khiav lag luam, kom cov xim, lub suab thiab ntawv pov thawj ntawm cov khoom tiav tsis txawv, kom ua tau raws li cov neeg yuav tsum tau ua. Nws tuaj yeem pom tau tias qhov kev tsis txaus siab tsis yog ua lub luag haujlwm ntawm kev tshawb xyuas tus txheej txheem loj, tab sis qhov tseem ceeb ntawm kev tswj cov txheej txheem qis dua.
Cov pov thawj tseem ceeb yog: kev tshuaj xyuas qhov tseeb, laser proofing, tsoos offset proofing thiab proofing. Vijtsam tshuaj xyuas yog ua los ntawm kev kho cov xim ntawm qhov screen kom cov duab ntawm qhov screen yog zoo ib yam nrog cov xim ntawm cov luam. Hom pov thawj no yog tsim rau cov neeg Asmeskas thiab cov neeg tsim khoom tsim. Qhov tsis zoo ntawm cov hom pov thawj no yog tias cov xim xim tsis ruaj khov thiab qhov txawv ntawm cov nyhuv luam tawm loj heev, thiab cov xwm txheej uas cuam tshuam rau qhov kev tshuaj ntsuam yog ntau dhau los tswj. Laser cov ntawv pov thawj tso cai rau koj kho cov duab ntxoov ntxoo ntawm txhua tus xim muaj xim hauv tshuab luam ntawv tsav tsheb. Siv cov zis curve kho lus cuab tam los ua tus number case xim ntawm lub tshuab luam ntawv tus thawj xim (CMYK) number case kom ze rau qhov tseeb thawj xim xim. Cov ntawv pov thawj no tsis muaj qhov tshwj xeeb rau tus neeg teb xov tooj kev txawj, nws yooj yim rau kev khiav lag luam, thiab cov ntaub ntawv tsis tas yuav hloov dua siab tshiab, tab sis nws nyob deb ntawm cov xim thiab theem ntawm cov teeb meem luam tawm. Hom kev tiv thaiv no feem ntau siv hauv kev lag luam advertising. Tshuaj tua hluav taws cov ntaub ntawv pov thawj yog qhov tseeb cov ntaub ntawv pov thawj. Cov khoom siv los ntawm txoj kev siv cov khoom no yeej zoo ib yam li qhov offset printing, li ntawd, cov xim gamut ntawm ob yog tib yam, thiab lub suab nrov ntawm qhov kev ua tau zoo li qub. Kev nplua nuj ntawm cov ntawv pov thawj tau muaj kev cai ntau dua rau tej yam kev mob thiab kev tswj xyuas. Yog li ntawd, cov kev txawj ua hauj lwm yuav tsum tau ua rau cov neeg ua hauj lwm ntawv pov thawj kuj tau siab dua, thiab tswj kev ruaj ntseg ntawm cov pov thawj xim thiab tsis zoo yog tsis yooj yim. Hom kev tiv thaiv no feem ntau nyob hauv cov tsev luam ntawv thiab qee cov tuam txhab uas tshwj xeeb hauv kev pov thawj. Nrog kev tsim cov tshuab luam ntawv, digital printing thiab CTP, cov txheej txheem luam ntawv tseem niaj zaus simplified, thiab cov ntaub ntawv pov thawj yog siv dav heev. Nws muaj ob feem ntawm: kev tswj xim software thiab luam ntawv. Cov luam ntawv feem ntau siv cov inkjet printers, xws li HP 5000, HP 10PS, EPSON 7600, EPSON 10000, thiab lwm yam., Thaum xim xim software feem ntau ua xim kho kom dhau los ntawm ICC profile.
Nrog kev txhim kho cov ntawv txuas ntxiv ntawm cov ntawv luam tawm ntawv, ntawv thiab xim xim software, cov ntawv pov thawj cov ntawv pov thawj tau tuaj ze dua thiab ze rau cov ntawv luam tawm. Txawm li cas los xij, ntau lub tshuab luam ntawv tseem nyuaj rau siv thaum siv cov ntawv pov thawj ua cov pov thawj luam ntawv. Tsis tas li ntawd, qee lub koom haum luam ntawv luam tawm tsis zoo, cov kev lag luam luam tsis yog cov qauv, cov ntawv pov thawj thiab cov ntawv luam tawm sib txawv, thiab qee qhov yog los ntawm kev tsis zoo ntawm cov luam ntawv thiab kev tswj xim software.
Yuav kom ua zoo siv cov ntaub ntawv pov thawj, peb yuav tsum them nyiaj rau cov teeb meem nram qab no:
1. Thaum xaiv ib lub tshuab luam ntawv, peb yuav tsum xav txog qhov xim xim ntawm lub tshuab luam ntawv, uas yog vim li cas qhov tshuab luam ntawv inkjet tam sim no ntau dua. Cov xim ntawm cov inkjet lub tshuab luam ntawv yuav ruaj khov ntev dua ib lub sijhawm, thiab tsis muaj qhov yuav maj mam pauv. Nyob rau hauv no hwm, laser printers muaj ntau tsim rau cov ntaub ntawv pov thawj.
2. Cov xim qhov chaw ntawm qhov cov ntaub ntawv pov thawj muaj qhov dav dua qhov chaw ntawm gamut, kom cov xim zoo tuaj yeem pom zoo dua.
3. Ua qauv ntawm cov qauv simulation sim, nws yog qhov zoo tshaj plaws los luam cov qauv, thiab tsis siv cov qauv pov thawj tshuaj. Vim hais tias kev tswj hwm, kev luam ntawv thiab kev luam ntawv ntawm kev txhim kho ntawm cov tshuaj tiv thaiv tau muaj qee yam txawv, cov ntaub ntawv pov thawj ntawm cov tshuaj tiv thaiv thiab cov ntawv luam tawm yog txawv. Cov ntaub ntawv pov thawj cov ntaub ntawv pov thawj tau siv los ntawm kev siv cov qauv no yuav ua rau kom tsis muaj teeb meem luam tawm thiab cov pov thawj.
4. Xaiv cov ntawv siv los ua cov ntaub ntawv pov thawj. Tsis yog txhua lub tshuab luam ntawv uas haum rau cov ntaub ntawv pov thawj. Thaum xaiv cov ntawv pov thawj cov ntawv pov thawj, koj yuav tsum xav txog cov xim ntawm daim ntawv, kev luam ntawm lub suab lus, thiab qhov dawb ntawm daim ntawv.
5. Thaum kho qhov xim ntawm lub tshuab luam ntawv, xav txog kev sib raug zoo ntawm lub tshuab luam ntawv thiab daim ntawv thiab tus cwj mem. Thaum twg daim ntawv los yog tus cwj pwm hloov, lub tshuab luam ntawv cwj pwm yuav tsum tau muab hloov dua tshiab.
6. Thaum hloov luam ntawv, khoom siv, ntawv, thiab khawm tus cwj pwm, qhov xim thiab lub suab ntawm cov ntawv tseem ceeb yuav hloov. Nyob rau lub sij hawm no, tus yam ntxwv cwj pwm ntawm cov luam ntawv tseem yuav raug muab hloov dua.
7. Sim siv tib lub spectrophotometer thiab cov ntaub ntawv tsim tsim software kom tiav lub profile tshuab luam ntawv thiab luam ntawv kom tsis txhob muaj kev sib txawv hauv cov pov thawj digital vim muaj kev sib txawv ntawm cov sib txawv spectrophotometers thiab profile creation software.
8. Hauv kev tswj xim software uas tuaj yeem kho qhov kev sib txuas ntawm lub tshuab luam ntawv, nws yog ib qho tseem ceeb kom hloov lub tshuab luam ntawv nti ua ntej ua qhov kev sib txuas ntawm tus qauv luam ntawv. Qhov ze ntawm lub tshuab luam ntawv ntim ntau dua rau qhov kev ceev ceev, qhov xim me ntsis yuav yog.
9. Xyuas kom tseeb tias cov kev saib xyuas pom zoo muaj raws nraim. Cov yam ntxwv ntawm cov phais hauv cov ntaub ntawv pov thawj yog txawv ntawm cov neeg luam ntawm cov ntawv luam tawm. Txawm hais tias cov ntaub ntawv pov thawj ntawm cov ntaub ntawv pov thawj thiab cov ntawv pov thawj pom zoo tib yam, muaj qhov tshwm sim ntawm qhov teeb meem metamerism. Thaum lub teeb pom kev zoo hloov, cov xim ntawm ob xim tsis ruaj khov kho. Thaum siv cov spectrophotometer los ntsuam xyuas cov xim rau thaj chaw, qhov tsim teeb tsa hauv nruab siab siv. Yog li, thaum coj mus kuaj pom, yuav tsum muaj lub teeb pom kev zoo, thiab D65 txheem qhov chaw yuav tsum tau muaj. Txwv tsis pub, txawv xim txawv yuav tshwm sim hauv qab sib txawv.
10. Thaum kawg, xyuam xim rau kev tswj cov xim txawv (△ E) ntawm cov ntaub ntawv pov thawj digital thiab cov ntawv luam tawm, thiab tswj cov xim txawv △ E hauv 5.0. Thaum △ E = 2.0, qhov muag tib neeg tsis xav tias qhov sib txawv hauv cov xim; thaum △ E = 3.0, tib neeg lub qhov muag tsuas pom qhov txawv ntawm xim; thaum △ E = 4.0, ob lub xim uas nyob ib sab muaj ntau nyuaj rau pom. qhov txawv.
Cov ntawv pov thawj muaj qhov zoo tshaj plaws ntawm kev ruaj ntseg thiab yooj yim ntawm kev siv, tab sis nws xav tau zoo dua hauv kev luam tawm. Ntxiv nrog rau cov neeg ua hauj lwm paub kho cov xim ntawm lub tshuab luam ntawv thaum pib ntawm kev yuav khoom, cov neeg ua hauj lwm tshwj xeeb yuav tsum tau ua. Ua kom lub tshuab luam ntawv zoo dua thiab kho cov xim kom lub sijhawm ntawd cov ntaub ntawv pov thawj ua rau nws ua tiav.
