Lub luag haujlwm ntawm txoj haujlwm no yog kom tau txais cov xim sib txawv ntawm cov xim los ntawm kev sib xyaw ntawm cov xim "ntshiab" cov xim superimposed ib qho ntawm lwm qhov. Nws yog ib qho tseem ceeb kom qhuav thawj txheej zoo ua ntej pib ua haujlwm nrog qhov thib ob, kom cov neeg kho tshuab sib xyaw ntawm cov ntxoov ntxoo tsis tshwm sim. Txwv tsis pub, koj tuaj yeem xaus nrog cov xim qias neeg, tsis zoo, thiab tsis yog tag nrho cov txiaj ntsig ntawm kev ua haujlwm uas koj xav tau. Tib yam siv rau tus naj npawb ntawm txheej. Lawv tsis ua ntau dhau. Nyob ntawm cov khoom siv, tsis pub ntau tshaj tsib yog siv rau ib cheeb tsam. Yog iboverdo nws, koj tuaj yeem, dua, tau txais cov xim qias neeg tsis yog qhov xav tau pob tshab pleev xim rau ntawm qhov pom kev ntawm cov khoom.

Txoj Cai Ua Haujlwm

Lub ntsiab tseem ceeb uas yuav tsum nco ntsoov yog glazing yog daim ntawv thov ntawm cov xim pob tshab, uas yog, cov xim yuav tsum tau diluted heev nrog dej los yog lwm yam tsim nyog muaj pes tsawg leeg. Cov xim rau daim ntawv thov feem ntau yog siv spectral, uas yog, tsis tov, tab sis cov uas koj twb muaj nyob rau hauv cov xim txheej. Piv txwv li, kom tau txais cov xim ntsuab ntsuab, cov keeb kwm yav dhau yog thawj zaug nrog daj hauv ib lossis ntau txheej, nyob ntawm seb cov xim yuav tsum tau siv, thiab tom qab ntawd xiav yog siv tib yam. Thaum cov khaubncaws sab nraud povtseg daj thiab xim liab yog optically sib xyaw, ntxoov txiv kab ntxwv tau txais. Nws tsim nyog nco ntsoov tias nws yog qhov zoo dua los siv cov txheej txheem sib dua ua ntej, piv txwv li, daj ua ntej, thiab xiav hla nws.

Xaiv cov kev xaiv yooj yim. Txhawm rau ua haujlwm los ntawm qhov xwm txheej, ua ib qho yooj yim ntawm ob peb yam khoom uas yuav tsis hloov txawm tias tom qab ob peb lub lis piam ntawm koj txoj haujlwm. Tsis txhob siv paj, txiv hmab txiv ntoo, lossis hloov cov khoom ntuj nrog cov khoom cuav.

Lwm txoj kev yog luam cov duab tiav. Nws yog qhov yooj yim dua yog tias koj tsis coj cov phiaj xwm nyuaj. Raws li thawj qhov kev paub dhau los, koj tuaj yeem xaiv ua ib daim duab zoo li no, uas muaj cov lus piav qhia ua haujlwm hauv cov duab lossis video hom.

Qhov feem ntau ntawm kev ua yuav ua raws li hauv qab no:

1. Xaiv ib zaj dab neeg thiab kos cov contours nrog cov kab nyias ntawm ib daim ntawv (xws li xim dej tshwj xeeb). Ua thawj txheej pob tshab tom qab. Nws tuaj yeem yog ib qho ntxoov ntxoo lossis tsim hauv txoj kev nyoos nrog kev hloov pauv ntawm cov suab nrov.

2. Qhuav thawj txheej thiab pib sau rau hauv thaj chaw ntawm daim duab nrog rau lwm cov pob tshab txheej, hla cov ntsiab lus tsim nyog raws li sab nrauv lossis sab hauv contour. Kev hloov ntawm ib qho xim mus rau lwm qhov hauv ib txheej yog qhov ua tau zoo tshaj plaws, yog tias cov no tsis yog ciam teb ntawm daim ntawv, xws li hauv qhov piv txwv ntawm cov duab hauv qab no.

3. Qhuav txheej tsim dua thiab siv tib lub thev naus laus zis los ua qhov thib peb.

Glazing hauv decoupage

Yog tias koj koom nrog kev tsim cov khoom plig uas siv cov ntaub so ntswg,cov txheej txheem ntawm txheej pob tshab xim kuj tuaj yeem ua ke. Txij li thaum tsob ntoo feem ntau siv los ua lub hauv paus rau kev ua haujlwm, txhua yam hais hauv ntu dhau los tuaj yeem siv tau yooj yim ntawm no.
