Font Candidate Selection for Print Inspection Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print quality inspection systems require users to set the correct font dictionary before inspection, which can be time-consuming and labor-intensive, especially when the user is unsure of the font type.
Innovation Solution
The system presents accurate font candidates to the user before confirming inspection settings, allowing the user to select the correct font from a list of registered fonts that match the similarity threshold with the character string in the inspection region.

Engineering Contradiction Analysis
1Measurement precision
If the user manually sets the correct font dictionary before inspection, then the inspection accuracy is improved, but the setup time and user labor are increased
Solution Approach 1:
The system performs preliminary font matching by comparing the inspection region character string against the font dictionary before the user confirms inspection settings. This preliminary action identifies and presents candidate fonts in advance, so when the user needs to set the font dictionary, the correct font is already identified or easily selectable, thereby reducing both setup time and labor while maintaining inspection accuracy
Solution Approach 2:
The system provides feedback to the user by displaying candidate font information based on the comparison result between the inspection region and font dictionary. This feedback mechanism guides the user to select the correct font dictionary without requiring the user to manually search through all available fonts, thus improving inspection accuracy while reducing setup time and user effort
2Measurement precision
If the user manually sets the correct font dictionary before inspection, then the inspection accuracy is improved, but the operation complexity is increased
Solution Approach 1:
The system performs preliminary font matching and presents candidate fonts to the user before inspection settings are confirmed. This preliminary action simplifies the operation by pre-identifying the correct font dictionary, so the user only needs to select from presented candidates rather than manually searching through all available fonts, thereby improving ease of operation while maintaining inspection accuracy
Solution Approach 2:
The system performs the font identification task automatically by comparing the inspection region character string with the font dictionary. This self-service mechanism reduces the operational burden on the user, as the system autonomously identifies candidate fonts and presents them for selection, thereby improving ease of operation while ensuring inspection accuracy through proper font matching

AI summary
An information processing apparatus is provided. The apparatus registers, in a candidate list, in association with an inspection region of the reference image set on the setting screen, font data as a candidate of reference font data as a reference for character recognition at the time of inspection of a printed product, and sets the reference font data on the setting screen in accordance with a user selection from the candidate list. In the registering, among preregistered registration font data, font data whose similarity with a character string of the inspection region of the reference image exceeds a threshold is registered in the candidate list.
