Solution Overview
Problem
Ink jet-type recording methods that use a reaction solution to enhance ink adhesion on recording media often face issues with degraded recording quality when excess reaction solution is applied, leading to reduced wear resistance and image quality.
Innovation Solution
A recording method and device that control the ejection amounts of ink and reaction solution as droplets, ensuring a relationship where the ejection amount in a first recording mode is greater than or equal to that in a second recording mode with lower speed, using a flocculating agent in the reaction solution, and determining these amounts based on environmental conditions and recording time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reaction solution is applied on the recording medium by an amount more than necessary, then ink adhesion is improved, but recording quality is degraded
Solution Approach 1:
The patent applies parameter changes by adjusting the ejection amount of reaction solution based on recording speed parameters. Specifically, when recording speed decreases, the ejection amount Op is reduced accordingly. This dynamic parameter adjustment prevents excess reaction solution application while maintaining adequate ink adhesion, thereby resolving the contradiction between adhesion improvement and recording quality degradation.
2Reliability
If the reaction solution is applied on the recording medium by an amount more than necessary, then ink adhesion is improved, but wear resistance is degraded
Solution Approach 1:
The patent implements parameter changes by dynamically adjusting the reaction solution ejection amount Op based on recording speed T. When recording speed is lower, the ejection amount is reduced to prevent excessive reaction solution from compromising wear resistance. This ensures that adequate but not excessive reaction solution is applied, maintaining both ink adhesion and wear resistance.
3Reliability
If the reaction solution is applied on the recording medium by an amount more than necessary, then ink adhesion is improved, but image quality is degraded
Solution Approach 1:
The patent applies parameter changes by controlling the ejection amount Op of reaction solution according to recording speed T and other parameters. By reducing Op when recording speed decreases, the patent prevents excessive reaction solution from degrading image quality while maintaining sufficient ink adhesion. This dynamic control ensures optimal image quality across different recording conditions.

AI summary
A recording method is for performing recording by ejecting, onto a recording medium, ink and a reaction solution including a flocculating agent that flocculates a substance contained in the ink, and the recording method includes ejecting the reaction solution as a droplet onto the recording medium, and ejecting the ink as a droplet onto the recording medium. A relationship of Op1≥Op2 is satisfied when an ejection amount of the reaction solution during ejecting the reaction solution in a first recording mode is indicated with Op1, and an ejection amount of the reaction solution during ejecting the reaction solution in a second recording mode is indicated with Op2, the second recording mode having a recording speed lower than the first recording mode.
