Glitter Developer Image Division Control for Luster Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image formation apparatuses face challenges in maintaining a stable metallic luster when printing with glitter developers, as the glittering property tends to increase over time and becomes unstable due to variations in particle size distribution and conductivity of the silver developer.
Innovation Solution
The image formation apparatus adjusts the division number and area ratio of the glitter developer image based on the remaining amount of the silver developer, dividing it more finely when the amount is higher and less coarsely when it is lower, to maintain a consistent metallic luster and color gamut throughout the usage of the developer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the glitter developer is used continuously, then the metallic luster increases over time, but the stability of the metallic luster deteriorates
Solution Approach 1:
The controller performs preliminary actions by detecting the remaining amount of glitter developer before printing and pre-adjusting the image division number and area ratio accordingly. This prevents the metallic luster from becoming unstable during actual use, as the adjustment is made in advance based on the developer's consumption stage.
Solution Approach 2:
The patent changes the parameters of image division number and area ratio based on the remaining amount of glitter developer. By dynamically adjusting these parameters as the developer is consumed, the system compensates for changes in particle size distribution and conductivity, thereby stabilizing the metallic luster throughout the developer's usage life.
2Manufacturing precision
If the division number is increased to maintain fine granularity, then the manufacturing precision improves, but the productivity decreases
Solution Approach 1:
The patent implements a dynamic adjustment strategy where the division number is not fixed but varies based on the remaining amount of glitter developer. When the remaining amount is high, a higher division number is used for fine granularity. When the remaining amount is low, a lower division number is used to maintain productivity. This dynamic parameter adjustment resolves the contradiction between precision and productivity.

AI summary
An image formation apparatus according to an embodiment may include: a first image formation unit including a storage part storing a glitter developer and configured to form a glitter developer image with the glitter developer; and a controller configured to control an operation of the first image formation unit based on print data received. The controller is configured to: when a remaining amount of the glitter developer in the storage part is a first remaining amount, to form the glitter developer image such that the glitter developer image is divided per unit area by a first division number; and when the remaining amount of the glitter developer in the storage part is a second remaining amount less than the first remaining amount, to form the glitter developer image such that the glitter developer image is divided per unit area by a second division number smaller than the first division number.
