Trap tseem hu ua trapping, tseem hu ua expansion thiab contraction, feem ntau yog los pab tiv thaiv cov xim dawb ntawm ob qho tib si xim txawv vim qhov tsis raug luam tawm overprinting.
Thaum tib neeg ua ntsej muag muag, lawv ib txwm xav tias qhov xim tsaus yuav ze rau tib neeg qhov muag, thiab qhov muag pom kev ntawm cov neeg lub qhov muag. Yog li ntawd, thaum lub sij hawm ntes tus thawj, nws yeej ib txwm sim kom tiv thaiv lub teeb xim nyob rau hauv qhov tsaus xim los ntawm raug. Cov xim dub saum toj no zoo tib yam los xyuas kom meej tias nws tsis cuam tshuam rau qhov pom kev zoo.
Lub hauv paus ntawm kev ua ntaiv
Qhov kev siv ntawm kev ua haujlwm yuav tsum tau ua raws li qee cov hauv paus ntsiab lus. Raws li ib txwm muaj tshwm sim, qhov xim tsis nthuav, xim tsis nthuav, thiab xim nthuav dav yam tsis loj zuj zus hauv av. Qee lub sij hawm, kev sib nrig sib txig sib luag kuj tseem ua tau. Nyob rau hauv cov rooj plaub tshwj xeeb, thim rov qab yuav tsum tau, thiab txawm tias qhov sib txawv ntxiv ntawm ob lub xim uas nyob ib sab los mus them rau qhov yuam kev ntawm qhov yuam kev, kom muaj qhov teeb meem zoo nkauj zoo nkauj.
Tus nqi ntawm kev ntes yog nyob ntawm cov yam ntxwv ntawm cov substrate thiab cov ntaub ntawv tshaj tawm ntawm cov tshuab luam ntawv. Feem ntau, qhov nyiaj trapping ntawm offset luam ntawv me me, thiab qhov ntau ntawm trapping ntawm gravure thiab flexo luam ntawv loj dua, feem ntau 0.2-0.3 hli, uas tuaj yeem txiav txim siab raws li tus neeg luam ntawv tseeb los yog yuav tsum tau ua.
Hom kev khawm
Muaj plaub lub ntsiab ntawm txoj kev ntaiv.
(1) Monochrome kab hla txoj kev tshaj: ntxiv lub teeb xim kab rau ntawm ntug kev thaiv cov xim, thiab xaiv tus kab cwj pwm raws li cov ntawv pov thawj.
(2) Khoom siv kab hluavtaws: ntxiv cov kab hluavtaws sab nrig ntawm qhov xim ntawm cov xim. Cov cwj pwm raug xaiv tsis raug xaiv rau kev tshaj tawm.
(3) Layering method: trapping yog tiav los ntawm kev tuav lossis nthuav cov ntsiab lus ntawm cov khaubncaws sab nraud povtseg.
(4) Kev hloov ua haujlwm: Lub ntsiab lus sab nrauv los yog sab nrauv nthuav tawm los ntawm kev hloov txoj haujlwm ntawm qhov taw tes rau ntawm qhov xim, thiab feem ntau yog siv hauv qhov cuab tam ntsig txog qhov kev sib tw.
Dawb ntaiv
Hauv kev luam yas, daim ntaub ntawv dawb ntawm cov ntawv tseem ceeb heev. Feem ntau, cov khoom yas los sis cov yas suab, nws yog ib qho tsim nyog siv dawb raws li kev pab, thiab qee zaus yuav tau nqa ob cov khaubncaws sab nraud povtseg dawb. Yuav kom tiv thaiv tau dawb nyob rau hauv cov xim thaiv los ntawm raug vim yog tsis muaj tseeb tshaj qhov qub, cov dawb retraction yuav tsum muab xam ua ntej luam ntawv.
1. Cov dawb retraction yuav tau nqa tawm raws li qhov tob ntawm cov xim los yog cov kev cai ntawm tus neeg muas zaub, thiab cov nqi retraction yog feem ntau 0.2-0.3 mm.
2. Yog qhov xim nris dawb thiab sab yog pob tshab, cov xim dawb tau muab rov qab los ntawm 0.3 hli rau hauv cov xim nris.
3. Thaum dub thiab kub muab tso rau hauv cov xim dawb, dawb yuav muab rov qab mus rau dub thiab kub los ntawm 0.5-1 hli.
4. Yog qhov xim nrig yog sib dua los yog tiaj tus, qhov nyiaj dawb rho tawm yog me me los yog tsis tau rov qab los. Piv txwv li, thaum cov feem pua ntawm cov xim thaj yog 30% thiab 50%, cov nyiaj dawb rho tawm yuav yog 0.15 hli; thiab thaum lub sij hawm poob ntawm cov npuas xim muaj tsawg dua 30%, xim dawb yuav tsis raug muab rov qab.
5. Thaum xuas looj txhuam hauv cov qauv nrig, dawb yuav tsum raug muab xam rau qhov kev tshem tawm oblique. Qhov cyan gradient yog dawb, lub cyan tsaus thiab dawb yog hli 0.2, thiab lub cyan dawb. Cov dawb yog 0.1 hli, uas muaj peev xwm raug pauv los ntawm qhov taw tes kis.
6. Yog cov xim pob tshab (tsis yog dawb ntawm tus cwj mem) yog nyob rau lwm cov xim, cov xim dawb hauv lwm cov xim yuav tsum muab rov qab los ntawm 0.2 hli; yog tias cov xim pob tshuam ncaj qha nyob dawb, cov dawb yuav tsum tau loj hlob los ntawm 0.2 hli rau cov xim pob tshab kom tsis txhob muaj teeb meem smearing.
