Nyob rau hauv cov txheej txheem ntawm nyias daim ntawv luam, peb feem ntau ntsib xws li ib qho phenomenon: qee zaus muaj kev sib txawv hauv cov kab rov tav ntawm cov ntawv xov xwm, qhov yuam kev yog feem ntau tsawg dua 1 hli, tab sis qee zaus nws nce mus txog 3 mus rau 4 hli. Thiab qhov sib nrug sib nrug ntawm chav tsev, qhov loj dua qhov yuam kev nyob rau hauv lateral. Tsis tas li ntawd, qee zaum qhov teeb meem ntawm overprinting kuj yog nyob rau hauv kab pheeb ces kaum kab ntawm qhov kev teeb tsa tag nrho, ib lub xov tooj yog daim lawm, thiab lwm qhov kawg tsis muaj qhov yuam kev me me. Los ntawm ntau xyoo ntawm kev xyaum, Anmei Mall pom tias cov teeb meem no yog los ntawm kev sib xyaw ntawm ob lub txheej txheem: daim ntawv noo noo thiab kev kub kom qhuav.
Kev ceev cov luam ntawv ntawm lub tshuab luam ntawv yooj yim yog ceev heev, qhov kub kom qhuav yog siab heev, thiab qhov kub ntawm daim ntawv no yeej zoo li qub. Nws yuav nqus tau noo noo li cas?
Muaj ob txoj hauv kev xa mus rau ntawm qhov dej ntawm cov ntawv. Ib qho yog nyob rau hauv qhov kev sib nkag siab. Tom qab cov ntawv yob tawm ntawm daim tawv nqaij, nyob hauv daim ntawv ntawm lub taub hau, qhov txheej ntawm sab xub ntiag ntawm daim ntawv tuaj yeem ua rau qee qhov dej tsis nkag hauv ntawv, thiab sab nraub qaum yuav qis dua. Feem ntau, daim ntawv yuav nce 2% mus rau 3% ntawm cov dej. Qhov thib ob, ntsuab luam tawm tam sim no yog tawm suab, thiab dej-raws li hauv qab no maj mam siv rau hauv gravure, xws li cov kua roj vanish. Yog tias cov xaum dej uas sau los ntawm cov dej loj tuaj, daim nplais ntawm daim ntawv tuaj yeem deformed los ntawm cov dej noo, thiab tom qab tau qhuav ntawm qhov kub siab, qhov chaw noo yuav ua kom tsawg thiab qhov loj ntawm daim ntawv yuav ua me dua. Yog hais tias qhov kub ntawm qhov cub sov so, qhov ntau dua nyob rau hauv daim ntawv yuav ua kom qhuav, qhov ntau dua qhov deformation thiab shrinkage ntawm daim ntawv, thiab cov overprinting yuav tshwm sim thaum luam ntawv tom ntej xim. Tsis tas li ntawd, seb cov dej hauv daim ntawv hauv lub vas sab yog cov tsoos tsho lossis tsis yog, yog cov ntsiab lus dej nyob hauv taub hau thiab tom qab ntawm daim ntawv yob tsis yog, qhov teeb meem no yuav tshwm sim.
Kev daws mus rau qhov sib tw ntawm nyias daim ntawv luam tawm yog ua kom nce qib zuj zus, txo cov cua kub, thiab txo cov cua sov kom qhuav, kom lub zauv luam xim xim tsis yog ua tsis raws li thiab tsis fade. Tsis tas li ntawd, ntau cov ntawv nrawm yuav ua rau daim ntawv dav dav kom hloov thaum lub sij hawm xa ntawv hloov txheej txheem, uas ua rau tsis zoo rau ib qho kev tshaj tawm. Txawm li cas los xij, ib qho kev tsom xam yuav tsum tau muaj thaum muaj teeb meem tau ntsib.
