Braille Test Chart Parameter Variation for Consistent Inkjet Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink jet printers for printing braille characters face variability in printing results due to the type of recording paper, leading to undesired outcomes.
Innovation Solution
An information processing apparatus generates test chart image data with differing parameters for first and second braille patches, which are transmitted to a printing apparatus to ensure consistent braille character formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ink jet printer ejects ink to form braille characters on recording paper, then braille characters can be printed, but printing results vary depending on recording paper type
Solution Approach 1:
The patent applies parameter changes by adjusting the ejection amount of ink for different braille patches based on detected printing characteristics. The control unit modifies ink ejection parameters dynamically according to the type of recording paper and the specific braille patch, enabling consistent braille character formation across different paper types while maintaining adaptability to various printing conditions.
2Ease of manufacture
If standard ink ejection is used for all braille patches, then printing process is simple, but printing results vary with different recording papers
Solution Approach 1:
The patent implements dynamics by transitioning from static standard ink ejection to dynamic adjustable ink ejection. The control unit dynamically adjusts ink ejection amounts for each braille patch based on detected printing characteristics and paper type, enabling precise control while maintaining ease of operation through automated parameter adjustment.
Solution Approach 2:
The patent applies feedback by detecting actual printing characteristics of braille patches and using this information to adjust subsequent ink ejection parameters. The control unit receives feedback from printing characteristic detection, processes this information, and modifies ink ejection settings accordingly, creating a closed-loop system that ensures consistent results.

Function Achieved in This Case
The solution ensures consistent and desired braille character printing by adjusting parameters for braille patches, addressing variability across different recording papers.
Implementation Method 1
The printer ejects ink onto the surface of the recording paper, thereby forming small protrusions

AI summary
An information processing apparatus includes a generator configured to generate test chart image data for causing a printing apparatus ejecting ink to print a test chart image including a plurality of braille patches, the plurality of braille patches including a first braille patch and a second braille patch, and a transmitter configured to transmit the test chart image data to the printing apparatus. The generator is configured to cause a first parameter related to a first dot included in the first braille patch to differ from a second parameter related to a second dot included in the second braille patch.
