Liquid Ejecting Head Glossy Layer White Ink Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid ejecting apparatuses, such as printers, are less efficient when using additional inks like white or silver ink for color expression, as the existing recording methods do not effectively utilize these inks to enhance color range and visual effects.
Innovation Solution
A liquid ejecting method that involves ejecting a gloss-based liquid to form a glossy layer, followed by ejecting a white-based liquid onto this layer, with the ejection amount of the gloss-based liquid being greater than that of the white-based liquid, to create a more effective and visually enhanced printing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If white ink or silver ink is used for color expression, then color range is expanded, but recording efficiency is reduced
Solution Approach 1:
The patent applies preliminary action by first ejecting the gloss-based liquid (silver ink) to form a glossy layer before ejecting the white-based liquid. This preliminary formation of the glossy layer enhances the subsequent white ink layer's brightness and visual effects, allowing efficient use of both ink types to expand color range while maintaining recording efficiency through optimized ejection sequencing.
2Illumination intensity
If gloss-based liquid is ejected first to form glossy layer, then brightness of white ink layer is enhanced, but ejection amount of gloss-based liquid must be greater than white-based liquid
Solution Approach 1:
The patent applies parameter changes by controlling the ejection amounts of the gloss-based liquid and white-based liquid to specific ratios. The gloss-based liquid is ejected in a first amount that is greater than the second amount of white-based liquid, with the ratio of first amount to second amount falling within a predetermined range. This parameter optimization ensures the glossy layer provides sufficient brightness enhancement while maintaining proper material consumption balances.

AI summary
After a gloss-based liquid is ejected from a liquid ejection head, which ejects liquid from nozzles of a nozzle row, to a predetermined position on a landing target to form a glossy layer, a white-based liquid is ejected onto the glossy layer to form a white layer, the ejection amount of the gloss-based liquid being greater than the ejection amount of the white-based liquid.
