Benefits of technology

The technical effect of this patented invention is that it allows for smoother printing with less nozzles over time without sacrificing accuracy or reliability.

Problems solved by technology

The technical problem addressed in this patent text relates to stabilizing the ejection velocity of ink without causing damage to the passivation layer caused by excessive heat or mechanical stress. Additionally, the use of stable materials like tin (Sn) in ink compositions helps maintain the ejection speed and length of time over multiple uses.
