Printer Paper Type Notification for Calibration Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrophotographic image processing apparatuses face challenges in maintaining consistent color density and mixed color gradation due to instability, leading to inappropriate image quality when printing on different types of paper, as existing calibration methods fail to confirm the correct paper type for calibration during printing.
Innovation Solution
An information processing apparatus connected to an image processing apparatus that acquires and stores information on the paper type used during calibration, allowing it to notify and ensure that printing is performed using a paper type with a generated calibration table, thereby preventing inappropriate image output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If calibration is performed for different paper types, then color accuracy is improved, but it becomes difficult to confirm which paper type corresponds to the generated calibration table
Solution Approach 1:
The system stores paper type information associated with each calibration table in a storage unit, and the notification unit provides feedback to the user about which paper type corresponds to the generated calibration table. This feedback mechanism ensures that the correct paper type information is preserved and communicated, resolving the contradiction between achieving color accuracy through calibration and maintaining awareness of the corresponding paper type.
Solution Approach 2:
The notification unit acts as an intermediary between the calibration process and the user. It retrieves and communicates paper type information from the storage unit, serving as a mediator that ensures the correct information is transmitted without loss, thereby maintaining the relationship between calibration tables and their corresponding paper types.
2Measurement precision
If the system stores detailed information about paper types and calibration tables, then color reproduction accuracy is improved, but device complexity increases
Solution Approach 1:
The notification unit extracts only the necessary paper type information from the storage unit when needed, rather than managing all calibration data centrally. This extraction approach reduces the complexity of the main system while maintaining the ability to provide accurate color reproduction information when required.
Solution Approach 2:
The storage unit autonomously stores and manages the association between paper type information and calibration tables without requiring complex external management systems. The notification unit simply queries this self-managing storage unit when needed, reducing overall system complexity while maintaining color reproduction accuracy.

AI summary
An information processing apparatus connectable to an image processing apparatus that performs printing using a sheet stored in a paper feed stage and classified as a paper type on which a calibration table has been generated, includes an a receiving unit configured to receive an instruction to perform printing, and a notification unit configured to refer to information on the paper feed stage acquired, and notify, in a case where the sheet classified as a paper type on which the calibration table has been generated is not stored in a first paper feed stage instructed to be used for printing when the receiving unit has received an instruction to perform printing, of a second paper feed stage that stores a different type of sheet from the type of sheet stored in the first paper feed stage.
