Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink jet recording type image forming apparatuses face significant processing time challenges in simulating the behavior of ink droplets across entire print regions due to the enormous number of droplets and varying settings, leading to lengthy calculations for accurate image quality evaluation.
Innovation Solution
An information processing apparatus that acquires physical property information of the recording medium and ink, along with device settings, to estimate the behavior of ink droplets and derive feature quantities related to image characteristics, thereby reducing processing time for image quality evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If simulation of each ink droplet behavior across entire print region is performed, then image quality evaluation accuracy is improved, but processing time increases significantly
Solution Approach 1:
The patent segments the print region into multiple divided regions and performs ink behavior simulation only in a selected subset of these regions rather than the entire print region. This segmentation allows the system to maintain evaluation accuracy in critical areas while reducing overall processing time by excluding less important regions from detailed simulation.
Solution Approach 2:
The patent applies partial action by performing complete ink behavior simulation only in specific divided regions where detailed evaluation is necessary, while using simplified or no simulation in other regions. This partial approach maintains sufficient image quality evaluation accuracy while significantly reducing the computational burden and processing time associated with simulating every droplet across the entire print region.
2Measurement precision
If setting information is reflected to simulate accurate ink behavior, then simulation accuracy is improved, but calculation time increases
Solution Approach 1:
The patent applies local quality by selectively reflecting setting information and performing accurate ink behavior simulation only in specific divided regions where such detail is necessary for accurate evaluation. In other regions, simplified simulation or pre-calculated models are used, maintaining sufficient accuracy while reducing the overall calculation time required to process all regions with full detail.

AI summary
An information processing apparatus includes a processor configured to: acquire physical property information on physical properties of a recording medium and on physical properties of ink to be ejected onto the recording medium and setting information on a setting of a device configured to eject the ink onto the recording medium, the ink including a first ink and a second ink; derive a feature quantity relating to characteristics of the ink by estimating behavior of a first ink to be ejected onto the recording medium and of a second ink to be ejected to a position adjacent to the first ink ejected, using the physical property information and the information on a setting to derive a feature quantity relating to characteristics of the recording medium; and output the feature quantity.
