We support development of the ink jet printer heads which are decisive factor in improving printer performance in terms of higher speed, higher image quality, and stability.

We conduct evaluations such as evaluation of the piezoelectric thin films of ink jet printer heads, and clogging analysis for nozzles.

Background

The nozzle discharge stability and durability of ink are related to blending and structure changes of the dispersant and resin component. Sumika Chemical Analysis Service contributes to improved performance of ink through investigations using special pre-treatment and analysis technology.

Test Items

Crystallinity/Orientation, thin-film observation, thin-film composition, nozzle clogging and foreign matter analysis
