1. Xim Subtraction Method: Ob xim sib tshooj, thiab qhov sib tshooj ntawm qhov sib tshooj tshem tawm cov xim xim lub teeb los ntawm ib leeg tom qab sib tov, kom lub teeb pom kev zoo los yog kis los ntawm cov xim sib xyaw yog txo.
Poob, tsim lwm yam xim, xim ua npub.
2. Peb lub ntsiab ntawm cov xim: xim, ci, thiab purity. Lub ntsiab tseem ceeb ntawm cov xim overlay printing yog tsim ntau hues los ntawm overlapping ib tug me me ntawm hues; Brightness: Lub degree ntawm cov xim qhov tob, qhov uas lub brightness yuav txo tau tom qab dye mixing, thiab brightness nce thaum lub printing txheej overlay paste muaj titanium dioxide thiab overlaps nrog lub hauv paus xim. Qhov tseem ceeb ntawm brightness nyob rau hauv overlay printing yog los txhim khu cov txheej ntawm cov luam ntawv; Purity: Lub saturation ntawm cov xim, qhov siab dua qhov purity, cov xim vivid ntau, cov xim sib tshooj ntau dua, thiab qis dua qhov purity. Kev tuav ntawm cov xim purity nyob rau hauv overlapping printing yuav tsum conducive rau lub brightness ntawm daim duab.
3. Kev sib xyaw thiab siv cov xim thawj hauv kev luam ntawv: Hauv kev xav, magenta, cyan, thiab daj yog peb lub ntsiab xim ntawm dyes thiab lub hauv paus rau tag nrho cov xim sib tov. Txawm li cas los xij, hauv kev luam ntawv, feem ntau siv dyes thiab coatings tsis muaj xim thawj xim, feem ntau zoo li liab, daj, thiab xiav. Txawm li cas los xij, cov xim ntau yam uas tsim los ntawm lawv cov xim sib tshooj yog me dua li ntawm magenta, daj, thiab cyan, thiab qhov ci ntawm cov xim txheej yog zoo dua li cov xim active thiab dispersed; Intermediate xim: sib tov ntawm ob dyes uas ze rau thawj xim, hu ua lwm yam xim, xws li txiv kab ntxwv, ntsuab, thiab ntshav; Hauv laminated luam ntawv, yog tias cov xim tsaus yog luam tawm ua ntej, nws nkag mus rau hauv cov ntaub. Thaum tib tus nqi ntawm cov xim laminated luam tawm, lub teeb xim zoo li tsaus. Yog hais tias lub teeb xim luam tawm, tib tus nqi ntawm laminated xim lub teeb zoo li lub teeb; Multicolor: Cov xim uas muaj peb lub ntsiab xim dyes yog hu ua polychrome, uas yog xim tertiary. Thaum peb thawj xim sib xyaw ua ke sib npaug, qhov qis tshaj qhov ci grey dub xim tuaj yeem tau. Thaum peb cov xim thawj tsis sib xyaw ua ke sib npaug, cov xim sib txawv polychrome tuaj yeem tau txais. Thawj cov xim uas muaj feem ntau ntawm cov xim inclination yog kas fes, tsaus ntsuab, lub ntiaj teb liab, thiab ntau yam tilted greys hauv laminated printing, uas yog tsim los ntawm ib zaug los yog ob zaug lamination;
4. Muaj peb txoj kev nthuav qhia xim rau xim overlay luam ntawv: khoom xim overlay luam ntawv, dot overlay luam ntawv, thiab ua ke ntawm cov xim xim thiab dot overlay printing. Muaj peb txoj hauv kev: txheej txheej, nquag, thiab dispersion, uas nthuav tawm txoj cai ntawm txoj kev txo cov xim. Nyob rau tib lub sijhawm, lub zog npog ntawm cov txheej txheej yog siab dua li ntawm cov active dispersion, thiab lub teeb xim yog tsom rau cov luam tawm tom qab. Lub active dispersion luam tawm ua ntej yog ib qho yooj yim rau nkag mus rau sab hauv ntawm cov ntaub, thiab cov stacked ntaub nto luam tawm tom qab yog yooj yim los ntxuav tawm thaum lub sij hawm ntxuav xab npum, yog li nws yog ntau tsom rau cov xim muab tshuaj txhuam ua ntej; Vim muaj cov titanium dioxide, daim npog ntsej muag tsuas yog siv tau rau kev luam ntawv dot overlay. Nws cov xim yog ua tiav los ntawm kev sib txuas ntawm cov xim dots, thiab cov xim kev taw qhia nyob ntawm qhov sib piv ntawm cov xim dot rau cov xim xim. Cov dot luam ntawv ntawm kev ua ub no, dispersion, thiab txheej yog ob qho txiaj ntsig ntawm cov xim xa mus thiab kev sib koom ua ke. Khoom xim overlay: xim blocks yog nias rau ntawm cov xim blocks, thiab lub hauv paus xim yog overlayed los tsim ib tug thib peb xim. Dot overlay printing: muab faib ua huab qauv overlay printing, tiaj dot overlay printing, huab qauv thiab tiaj dot ua ke overlay printing; Huab qauv overlay: Tib xim huab qauv overlay: feem ntau qhia txog kev hloov ntawm cov khaubncaws sab nraud povtseg los ntawm kev hloov lub ci ntsa iab thiab qhov tob ntawm cov xim, thiab cov qauv ntawm kev nthuav qhia yog nplua nuj thiab tuab dua ib txheej huab txheej. Huab qauv overlay ntawm cov xim sib txawv yog cov ntsiab lus tseem ceeb ntawm huab qauv overlay. Txoj kev no yog siv rau hauv kev luam ntawv kom ua tiav cov nyhuv ntau xim ntawm overlay printing, ua rau cov xim nplua nuj; Flat dot printing: Nws yog ib hom kev luam ntawv luam tawm, xws li 30% uniform dot luam ntawv liab, uas pom lub teeb liab ntawm daim ntaub bleached, thiab tom qab ntawd 30% uniform dot luam ntawv daj, uas pom lub teeb txiv kab ntxwv, thiab lwm yam. Lwm cov xim ntawm lub tiaj dot luam ntawv sib tshooj nrog ib leeg, uas tuaj yeem tsim cov xim thib peb, tab sis cov ntaub tsis yog qhov tseeb thiab ci li ntawv;
5. Kev sib tshooj ntawm cov xim thiab cov ntsiab lus: Kev sib tshooj ntawm cov nquag, tawg, thiab txheej txheej huab nrog cov xim xim yog feem ntau ua tiav los ntawm nias lub teeb xim blocks ntawm cov qauv huab tsaus. Overprint paste tuaj yeem luam cov qauv huab cua sib zog ntawm cov keeb kwm yav dhau los, ua kom cov txheej txheem thiab cov xim hloov ntawm cov xim xim luam ntawv.
6. Kev sib cais xim thiab kev tshuaj ntsuam rau kev luam ntawv overlay: Khoom xim xim overlay luam ntawv: shrinkage ntawm 1-2 kab rau cov cheeb tsam uas muaj xim loj dua cov xim me me; Cov ntaub zoo shrinks 1-2 kab piv rau cov ntaub coarse; Nrog tib tus qauv, tus txheeb ze shrinkage ntawm active thiab dispersed txheej yog 1-2 kab, tab sis cov txheej slurry yog me dua thawj ob; Dot overlay: Huab overlay: Cov nyhuv ntawm huab overlay nyob ntawm kev xaiv thiab tswj cov xim sib cais thiab kev tshuaj ntsuam; Huab qauv luam ntawv tuaj yeem muab faib ua ob hom: tsis tu ncua thiab tsis xwm yeem. Cov ntsiab lus tseem ceeb ntawm kev tshuaj ntsuam ib txwm muaj xws li cov duab kos, ntsuas lub kaum ntse ntse, tshuaj ntsuam greyscale, thiab tus lej ntawm cov kab ntsuas. Cov duab uas nyiam tshaj plaws rau cov dot network yog lub voj voos, nrog rau qhov siab mesh suav rau cov hlau mesh. Tus naj npawb ntawm cov hlau mesh tuaj yeem nce ntxiv, tab sis cov txheej txheem yuav tsum tsawg.
