Cov ntawv pov thawj digital yog ib hom kev pov thawj thev naus laus zis uas ua cov ntawv sau hauv tshuab hluav taws xob digitally thiab tso tawm ncaj qha rau hauv kev tshaj tawm hluav taws xob. Nws yog dav siv vim nws qhov zoo xws li kev ceev, yooj yim, thiab tsis xav tau phaj ua. Thaum lub sijhawm ua qauv, cov neeg siv khoom feem ntau qhia txog cov teeb meem xws li "cov qauv qis" thiab "tsis zoo". Kev nkag siab txog cov xwm txheej hauv qab no uas cuam tshuam rau cov qauv digital tuaj yeem pab cov lag luam sai sai txheeb xyuas cov teeb meem thiab txhim kho kev luam ntawv zoo.
1. Kev luam ntawv raug
Kev ua haujlwm ntawm lub tshuab luam ntawv inkjet lub taub hau luam ntawv yuav cuam tshuam ncaj qha rau cov txiaj ntsig ntawm kev pov thawj digital. Kev luam ntawv tseeb uas lub taub hau luam ntawv tuaj yeem ua tiav txiav txim siab qhov tseeb ntawm cov ntaub ntawv pov thawj digital, thiab cov tshuab luam ntawv tsis tshua muaj peev xwm ua tau raws li qhov xav tau ntawm kev pov thawj digital. Kab rov tav qhov tseeb ntawm lub tshuab luam ntawv yog txiav txim siab los ntawm kev faib tawm ntawm lub taub hau luam ntawv, thaum qhov tseeb ntsug yog cuam tshuam los ntawm stepper lub cev muaj zog. Yog tias daim ntawv tsis pub noj kom zoo, cov kab kab rov tav yuav tshwm sim, uas tuaj yeem cuam tshuam rau kev luam ntawv raug. Txhawm rau kom ntseeg tau qhov tseeb thiab qhov tseeb ntawm cov duab luam tawm, nws yog ib qho tsim nyog yuav tsum tau ua kom zoo thiab tswj xyuas lub tshuab luam ntawv ua ntej kev pov thawj digital.
Tsis tas li ntawd, qhov kev daws teeb meem ntawm cov ntawv luam tawm kuj yuav tsum tau tswj nyob rau hauv ib qho kev ua kom pom tseeb thiab cov ntsiab lus ntawm cov ntawv luam tawm. Nyob rau hauv cov nqe lus ntawm kev ua cov duab, cov duab zoo ua software tuaj yeem siv los ua cov ntawv luam tawm los txhim kho cov duab meej thiab raug. Lub caij no, thaum lub sij hawm luam ntawv, nws yog ib qho tsim nyog los tswj txoj hauj lwm thiab txav ceev ntawm cov ntawv luam tawm kom ntseeg tau qhov tseeb thiab qhov tseeb ntawm daim duab. Yog li ntawd, kev hloov kho thiab kev tswj hwm ntawm lub tshuab luam ntawv, cov duab ua haujlwm zoo tshaj plaws, tsim nyog luam ntawv thawj qhov kev daws teeb meem, thiab tsim nyog luam ntawv ceev thiab txoj hauj lwm yog tag nrho cov ntsiab lus tseem ceeb los xyuas kom meej meej thiab raug ntawm cov duab luam tawm.
2.Printing number case
Qhov tseeb xim yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm cov khoom luam tawm hauv cov txheej txheem luam ntawv digital. Hauv cov txheej txheem luam ntawv, txhawm rau kom ua tiav cov xim zoo tshaj plaws, lub tshuab luam ntawv yuav tsum tau faib cov xim thiab cov suab kom raug, nrog rau kev tswj xyuas cov xim sib npaug thiab qhov sib npaug grey ntawm cov khoom luam tawm.
Qhov chaw siv xim feem ntau yog CMYK xim qhov chaw, uas ua tiav cov xim uas xav tau los ntawm kev kho cov proportions ntawm Cyan, Magenta, Daj, thiab Dub xim. Txhawm rau kom ntseeg tau cov xim raug, cov tshuab luam ntawv feem ntau yog nruab nrog cov cuab yeej tshwj xeeb tshawb pom xim kom pom thiab kho cov xim thiab lub suab ntawm tus number case. Tsis tas li ntawd, nws yog ib qho tsim nyog los kho qhov sib npaug ntawm cov xim thiab qhov sib npaug grey ntawm cov ntawv luam tawm kom ntseeg tau tias qhov tseeb thiab sib xws ntawm cov xim ntawm cov ntawv luam tawm. Yog li ntawd, nyob rau hauv cov txheej txheem ntawm kev luam ntawv, kev tswj kom meej thiab kev hloov ntawm tus cwj mem xim thiab lub suab, nrog rau cov xim thiab greyscale tshuav nyiaj li cas ntawm cov khoom luam tawm, yog cov kauj ruam tseem ceeb los xyuas kom meej cov xim ntawm cov khoom luam tawm.
3. Ntawv luam ntawv
Cov ntawv pov thawj digital muaj cov kev xav tau siab rau cov duab luam ntawv zoo, daim ntawv glossiness, thiab kev hloov pauv ntawm daim ntawv, thaum cov ntawv luam tawm cov duab yuav tsum tsis tshua cuam tshuam los ntawm kev hloov pauv ib puag ncig. Cov ntawv pov thawj digital yuav tsum muaj tus cwj pwm zoo, nqus tau sai ntawm cov number case droplets, thiab tsis muaj kev sib txuam ntawm cov cwj mem lossis xim xim thaum daim duab luam tawm; Cov duab luam tawm muaj cov dej tsis zoo, kev tsim cov xim zoo, cov khaubncaws sab nraud povtseg, siab saturation, dav xim gamut, siab cov duab daws teeb meem, thiab cov xim zoo ntawm cov qauv tso zis; Qhov saum npoo ntawm daim ntawv yog ilv thiab uniform, muaj peev xwm hloov mus rau qhov hloov maj mam sib txawv ntawm ntau hom qauv thiab inks.
Raws li kev siv cov ntawv pov thawj digital, nws tuaj yeem faib ua peb pawg:
Qhov zoo ntawm cov ntawv pov thawj digital yog ib feem tseem ceeb ntawm kev tswj xim hauv cov ntawv pov thawj digital. Hauv kev tsim khoom tiag tiag, cov ntaub ntawv pov thawj digital feem ntau siv cov ntawv luam ntawv imitation copperplate. Ntawm qhov tod tes, nws muaj txheej txheej haum rau luam ntawv number case; Ntawm qhov tod tes, nws muaj cov xim zoo sib xws rau tooj liab coated ntawv siv rau kev luam ntawv, ua kom yooj yim rau kev ua tiav tib yam li cov xim luam ntawv. Raws li cov neeg siv khoom xav tau, xaiv cov ntawv pov thawj digital uas tsim nyog thiab ua haujlwm tau zoo thiab cov ntaub ntawv sib xyaw xim sib xyaw ua ke (cov tshuab luam ntawv, xim tswj software, number case, thiab lwm yam) tuaj yeem ua kom qhov kev simulation ntawm cov khoom luam tawm los ntawm kev pov thawj digital.
