Ua kom tiav cov xim tiag, nws yuav tsum tau los siav ob yam kev mob raws li qhov tseeb ntawm Hawj: thawj, xim muaj ntau dua kev tuaj yeem, uas yog, purity zoo dua. Qhov thib ob xim muaj qis dua. Ntxiv mus, nyob rau hauv no, peb yuav tsum xyuam xim rau cov teeb meem nram qab no:
1 substrate
Lub substrate yog lub hauv paus rau qhov kaj xim ntawm cov teeb meem luam tawm. Raws li cov kev cai xim ntawm cov ntawv luam tawm, ntxiv nrog rau qhov sib xyaw kom haum ntawm cov xim me ntsis los ntawm cov khoom siv xim ntxiv rau txoj kev pom xim ntawm cov neeg, tsis muaj xim ntawm cov nplaim ntawm cov substrate uas dot yog luam tawm . Nyob rau hauv qhov tseeb, nws kuj yog koom tes nyob rau hauv no spatial mix. Yog li ntawd, yog hais tias tus dawb ntawm lub substrate yog high, lub ci ci ntawm cov xim yuav kho. Ntawm qhov tsis sib xws, qhov grey substrate zoo li muab me me nyiaj dub rau txhua tus cwj nrag xim, uas qhia tau tias yog ib tug npub xim. Tsis tas li ntawd, tus nqi ntawm substrate absorbency yuav cuam tshuam rau kev tuaj yeem ntawm cov xim. Rau cov substrates nrog absorbency siab, qhov kev ua luam tsis tuaj yeem tsim ib daim ntawv puv ntim quav rau saum npoo, thiab lub khob cij feem ntau nkag mus rau hauv lub substrate kom qhuav lub plab. Daim ntawv nrog cov loj pores yuav ua rau qee cov pigments mus rau hauv daim ntawv nrog tus binder, yog li txo cov xim xim thiab cuam tshuam lub vividness ntawm cov xim.
2 plhaub
Cov xim yam ntxwv ntawm peb lub ntsiab xim xim ncaj qha cuam tshuam rau cov neeg kawm ntawv qib siab ntawm cov teeb meem loj. Cov xim, grayscale thiab kev ua haujlwm ntawm peb thawj xim xim sib txawv ntawm cov qauv ua txawv, yog li cov vivideness ntawm tus cwj pwm xim tseem txawv. Yog li, thaum luam ntawv zoo, nws yuav tsum Siv tib hom xim muaj suab npe hauv tib lub khw. Ntxiv mus, thaum lub sij hawm luam ntawv, sim tsis ntxiv cov neeg pab txhawb ntau rau tus thawj tus cwj mem los ua tus number case emulsification los yog saturation txo. Thaum hloov xim, yog tias tsis muaj xim tom ntej zuag, nws yuav ua rau xim hloov ntawm cov xim tom kawg tom qab, thiab qhov txho qib yuav nce, uas cuam tshuam rau cov xim luam ntawm cov teeb meem luam tawm.
3 daim hlau
Feem ntau ntawm cov ntawv uas siv rau hauv dej luam tawm yog PS daim hlau. Cov PS version yog ua raws li cov duab ntawm cov duab hluav taws xob (polymer layerensitive) ua ib daim duab nrawm, thiab cov ntawv phaj duab yog me ntsis siab tshaj qhov seem. Feem xyaw hydrophilic yog ib qho yeeb yaj duab ntawm txhuas oxide. Waterless offset luam ntawv siv ib hom ntawv uas muaj menyuam ua ntej luam tawm cov ntawv luam tawm. Qhov seem ntawm yog ib qho silica gel uas rov qab ua piv txwv. Cov duab seem yog ib txheej ntawm ib nyuag concave polymer, thiab cov nplaim ntawm lub phaj yog resistant rau oxidation. Qhov zoo ntawm PS version ncaj qha cuam tshuam qhov zoo ntawm cov luam.
4 Plhaub taum txheej txheej
Nyob hauv cov ntaub ntawv luam tawm, lub thickness ntawm tus number case txheej yuav cuam tshuam cov xim tu tub tu kiv. Lub thickness ntawm tus number case txheej yog nyias, thiab daim duab yog grey thiab npub; lub thickness ntawm tus number case txheej yog tuab, tus nqi loj ntawm qhov teev yog ntau zog, thiab tsaus nti yog yooj yim rau paste, thiab cov duab yog npub thiab theem tsis meej. Yog li, lub thickness ntawm tus number case txheej yuav tsum tau balanced nrog cov laus tu tub tu kiv. Feem ntau, lub plawv ntawm cov plhaub txheej yuav tsum muab kho raws li cov qauv muab, uas yog qhov zoo ntawm lub phaj yog guaranteed. Rau cov tshuab monochrome, them nyiaj tshwj xeeb kom paub lub npe ntawm tus thawj xim. Lub thickness ntawm thawj xim xim plhu txheej ncaj qha cuam tshuam cov xim kev luam ntawm tag nrho cov duab.
5 overprint tus nqi
Tus piv txwv tshaj qhia tau hais tias tus nqi ntawm tus number case number nyob rau hauv cov xim dhau los rau tus nqi number case luam ncaj qha rau ntawm daim ntawv nyob rau tom kawg xim. Qhov sib piv yog ib qho tsawg tshaj li 100%, uas txhais tau hais tias tus nqi ntawm tus cwj mem muab luam tawm nyob rau hauv cov xim dhau los yog qhov tsawg tshaj tus nqi number case luam ncaj qha rau ntawm daim ntawv tom kawg ntawm xim.
Qhov luaj li cas ntawm qhov kev cuam tshuam feem xyuam rau kev tuaj yeem ua xim ntawm lwm yam xim. Tus nqi ntau tshaj yog loj, qhov xim ntawm qhov xim loj, thiab xim zoo nkauj dua. Rau lub tshuab monochrome, feem ntau tus nqi tshaj yog feem ntau siab dua, thiab rau lub tshuab siv ntau yam, tsis yog tus nqi ntau tshaj qhov tsawg tsawg xwb, tab sis cov xim txawv ntawm lub hauv ntej thiab nram qab xim xim.
6 qhov kev nthuav dav
Hauv kev xa ntawv luam tawm, qhov kev mob loj yog kev tsis pom zoo, tab sis qhov loj ntawm qhov txiaj ntsig ntawm qhov poob yog kev tswj tau. Yog hais tias qhov dot enlarged, cov xim yog tus ci. Ntawm qhov tsis sib xws, cov dot yog loj dua, thiab loj dua cov xim, lub thickness ntawm tus number case txheej yuav tsum tau txo kom tseeb tseeb ntawm cov Hawj. Qhov no ua rau lub suab tsaus nti thiab cov khoom seem tsawg thiab cov xim tsis muaj zog. Li no rau lub xim ntawm tag nrho cov duab.
