1. Zam kev sib xyaw nrog cov kuab tshuaj hnyav-based:
Dej-based inks yuav tsum tsis txhob sib xyaw nrog cov kuab tshuaj khov kho. Thaum kho cov viscosity los yog ziab nrawm thaum siv, koj yuav tsum ntxiv cov cawv me me lossis esters li cov tshuaj ntxiv.
2. Do ua ntej siv:
Txhua lub sijhawm ua kom tus ntxhiab tsw zoo ua ntej ywg nws mus rau hauv lub taub hau tais. Kho lub viscosity siv dej raws li xav tau ua ntej pib cov txheej txheem luam ntawv.
3. Kuaj cov cim qhia:
Ua ntej siv, pov thawj tias cov kev qhia kev ua haujlwm ntawm tus cwj pwm ua tau raws li cov qauv yuav tsum tau ua.
4. Saib xyuas viscosity thiab pH thaum lub tshuab luam ntawv:
Lub evaporation ntawm dej thaum lub tshuab luam ntawv tuaj yeem hloov viscosity thiab PH ntawm number case. Nquag xyuas viscosity thiab pH, thiab yog tias tsim nyog, ntxiv lim kom huv dej dej lossis ph stabilizer kom muaj kev sib xws.
5. Huv si tom qab siv:
Tom qab luam ntawv, ntxuav tus number case seem rau ntawm cov cuab yeej luam ntawv nrog cov dej huv los npaj rau kev sib txuas lus tom ntej.
