Ntim thiab luam ntawv number case xim uniformity, ci thiab ntshiab xim yog qhov tseem ceeb ntawm kev ntim khoom zoo, thiab luam ntawv xim sib txawv yog ib qho teeb meem ntawm cov khoom luam tawm zoo. Yog li dab tsi yog vim li cas rau cov xim sib txawv hauv kev ntim khoom?
Tib neeg yam: Nws tsis muaj dab tsi ua rau tus thawj coj' qib kev txawj ntse, tab sis nws muaj feem cuam tshuam rau tus thawj coj' lub luag haujlwm ntawm kev paub. Txij li cov xim ntawm tib batch ntawm cov khoom tuaj yeem ua tau zoo ib yam, nws qhia tau hais tias tus thawj coj' qib kev txawj tsis qis, tab sis vim li cas nws tsis sib haum nrog cov qauv thiab twv kom luam tawm? ? Thawj tus qauv puas tau kos npe? Qhov no yog tag nrho cov lus nug ntawm tus thawj coj' kev paub txog lub luag haujlwm. (Nws tseem tsis tau txiav txim siab qhov yuam kev hauv kev kos npe rau tus qauv, yog tias nws yog, nws muaj feem xyuam rau lub luag haujlwm ntawm tus neeg kos npe rau tus qauv).
Daim ntawv xim: Cov ntawv uas muaj xim sib txawv muaj qhov sib txawv ntawm cov xim ntawm cov xim luam ntawv. Vim tias qhov sib txawv ntawm cov xim dawb yog sib npaug rau qhov sib txawv ntawm cov xim dub, liab, xiav lossis daj rau tus number case, txawm hais tias tus number case ntim thiab xim tsis hloov pauv hauv kev luam ntawv, tus number case tiag tiag muaj qee qhov kev pom tseeb, thiab cov nyhuv xim txawv nrog cov xim dawb. ntawm daim ntawv. Qhov txawv tshwm sim, ua rau sib txawv chromatic aberrations. Thaum qhib cov khoom, nws yog ib qho tsim nyog yuav tsum siv tib daim ntawv. Vim tias qhov hnyav, qhov tshwj xeeb, thiab qhov loj me yog tib yam, tab sis cov khoom lag luam batch naj npawb thiab hnub sib txawv, cov xim dawb ntawm daim ntawv yuav muaj qhov sib txawv, uas yuav ua rau cov xim sib txawv ntawm cov khoom luam tawm. Yog li siv tib daim ntawv dawb li cov ntawv luam ntawv ntawm tib yam khoom.
Daim ntawv gloss thiab smoothness: Lub gloss ntawm cov ntawv luam tawm nyob ntawm qhov gloss thiab smoothness ntawm daim ntawv. Offset xim luam ntawv yog thaum lub teeb tshwm sim rau ntawm daim ntawv, lub teeb yog reflected mus rau retina ntawm tib neeg lub qhov muag, thiab cov xim yog pom los ntawm photosynthesis tau txais los ntawm cov xim-sensing hlwb. Yog hais tias lub gloss thiab smoothness ntawm daim ntawv siab, cov xim peb saib yog cov xim uas tshwm sim los ntawm cov number case txheej, thiab lub ntsiab xim lub teeb saturation yog siab. Yog hais tias lub nto ntawm daim ntawv yog ntxhib thiab gloss yog tsawg, nws yuav tsim diffuse reflection, uas yuav txo tau cov saturation ntawm lub ntsiab xim lub teeb, thiab ua rau cov xim xaav ntawm cov luam ntawv lightened los ntawm peb ob lub qhov muag. Tib tus number case yog siv los ntsuas tus nqi ntom nrog lub densitometer. Daim ntawv nrog siab smoothness thiab gloss muaj tus nqi siab ceev. Daim ntawv uas tsis tshua muaj smoothness thiab gloss muaj tus nqi tsawg.
Kev kho deg ntawm cov ntawv luam tawm: Tom qab kev kho deg xws li laminating, varnishing, calendering, oiling, thiab luam ntawv, cov ntaub ntawv luam tawm yuav muaj ntau yam kev hloov xim. Qee qhov kev hloov pauv no yog kev hloov ntawm lub cev, thiab qee qhov yog kev hloov tshuaj lom neeg. Cov kev hloov ntawm lub cev yog feem ntau yog tshwm sim nyob rau hauv qhov nce ntawm specular reflection nyob rau saum npoo ntawm cov khoom, uas muaj ib tug tej yam ntxim rau cov xim ceev. Piv txwv li, compound lub teeb zaj duab xis, UV kua roj vanish, calendering, thiab lwm yam., cov xim ceev yuav nce. Cov xim ntom ntom ntawm cov khoom luam tawm raug txo qis tom qab sub-film thiab cov roj matte siv. Cov tshuaj hloov pauv feem ntau yog los ntawm laminating kua nplaum, kua roj vanish, UV roj thiab lwm yam. Cov ntaub ntawv no muaj ntau yam kuab tshuaj, thiab lawv txhua tus ua rau cov xim ntawm cov luam ntawv number case los ntawm cov tshuaj tiv thaiv ua rau cov xim hloov. Yog li ntawd, raws li cov ntaub ntawv luam tawm rau kev ntim khoom offset luam ntawv, yog tias muaj cov txheej txheem tom qab luam ntawv thaum lub sijhawm luam ntawv, kev hloov pauv ntawm lub cev thiab tshuaj lom neeg ntawm cov txheej txheem tom qab luam ntawv yuav tsum raug coj mus rau hauv tus account kom txiav txim siab tus nqi ntom thiab Lab tus nqi ntawm cov number case txheej. thaum luam ntawv.
Dry retreat density value: Tus number case tseem ntub tom qab cov khoom luam tawm offset luam tawm, tus nqi ntom ntom ntsuas ntawm lub sijhawm no txawv ntawm tus nqi ntom ntsuas tom qab cov ntawv luam tawm qhuav. High density value thaum ntub, tsis tshua muaj nqi thaum qhuav, qhov no yog qhov tshwm sim ntawm qhuav degraded ceev tus nqi. Qhov no yog vim hais tias tus number case txheej tsuas yog luam tawm muaj ib theem ntawm leveling. Nws yog tsuas yog manifested los ntawm specular xav txog ntawm qhov chaw, uas zoo nkaus li kaj nyob rau hauv cov xim thiab zoo luster. Thaum tus number case txheej dries, yuav muaj diffuse reflection rau ntawm qhov chaw, thiab lub ntuj gloss yuav tshwm sim npub thiab npub tshaj li thaum thawj zaug luam tawm. Txhawm rau kom ntseeg tau tias cov xim sib txawv ntawm cov khoom batch raug txo kom ntau li ntau tau thaum lub sij hawm luam ntawv ib txwm, peb txais yuav tib txoj kev ntsuas ntub dej kom tswj tau.
Printing siab: Printing siab yog ib qho ntawm cov xwm txheej rau kev hloov tus cwj mem. Txij li qhov saum npoo ntawm daim ntawv luam ntawv, daim pam, thiab lwm yam tsis tuaj yeem ua kom du, qhov saum npoo ntawm daim ntawv kuj tseem tsis tuaj yeem muaj qhov tsis sib xws lossis tsis sib xws. Yog tias lub tshuab luam ntawv tsis txaus lossis tsis sib xws, cov txheej txheem number case yog qhov tsis sib xws. Yog li ntawd, cov txheej txheem yuav tsum tau" peb lub tiaj tus", uas yog, qhov chaw ntawm lub phaj luam ntawv, daim pam, lub substrate thiab hauv ob sab phlu nto yog tag nrho cov tiaj tus. Nws tsuas yog ua tau kom tau txais cov xim xim xim ntau dua ntawm cov ntawv luam tawm nrog cov xim nyias nyias los ntawm kev sib npaug ntawm cov luam ntawv siab. Thaum lub tshuab luam ntawv tsis txaus lossis tsis sib npaug, thiab muaj kev sib cuag tsis zoo ntawm lub cev hauv ob sab phlu thiab cov phaj luam ntawv saum npoo, nws yog ib qho tsim nyog yuav tsum tau ua kom cov number case kom tau raws li qhov pom kev ntawm luam ntawv ntawm lub phaj phaj. Txawm li cas los xij, qhov no yuav tsis tsuas yog nce tus cwj mem noj xwb, tab sis kuj yooj yim tsim cov xim sib txawv thiab smearing ntawm cov khoom luam tawm, yog li ua haujlwm zoo ntawm" peb flats" (tus number case rau lub tiaj tus, cov dej rau cov menyuam tiaj tus, lub tog raj kheej tiaj tus) thiab siv cov khoom sib xws thiab cov ntawv luam tawm tas li, txhawm rau tiv thaiv cov chromatic aberration los ntawm lub siab tsis zoo.
Saib ntawm lub teeb ci ntawm lub rooj qauv: Thaum saib cov xim ntawm cov khoom offset luam tawm, yuav tsum muaj lub teeb ci. Yog tsis muaj lub teeb, xim tsis tuaj yeem pom. Txawm li cas los xij, yog tias cov yam ntxwv ntawm lub teeb ci sib txawv, cov xim sib txawv yuav loj heev. Feem ntau, peb qhov yuav tsum tau ua yog saib cov xim nyob rau hauv tej yam ntuj tso teeb pom kev zoo (uas yog, qauv teeb qhov chaw). Yog tias lub teeb hluav taws xob zoo tib yam siv los ua lub teeb ci los saib cov xim, ces cov xim yuav tshwm daj, nws nyuaj rau kev txheeb xyuas cov xim kom raug, thiab cov khoom luam tawm yuav muaj xim loj. Tsis tas li ntawd, qhov siv ntawm lub teeb thiab lub kaum sab xis ntawm lub teeb pom kev zoo kuj tseem cuam tshuam rau kev txheeb xyuas xim. Nyob rau hauv tib lub teeb ci, qhov kev siv ntawm lub teeb pom kev ntawm lub teeb pom kev zoo yog txiav txim siab los ntawm qhov kev ncua deb ntawm cov pov thawj thiab lub teeb ci.
