介绍了水性油墨粘度和pH稳定性对于印刷质量的影响，针对目前水性油墨粘度和pH稳定性差的问题，提出了利用胺化试剂来提高其粘度和pH稳定性的方法，通过利用多种胺化试剂进行对比实验，寻求出了最佳解决方案。

The influence of viscosity and pH stability of water-based ink on printing quality was introduced. A method to improve viscosity and pH stability using amine reagent was put forward to current problem of the low viscosity and pH stability. The best solution was found out by comparative experiments on a variety of amine reagents.
