Inkjet Print Setting Control for Low-Curl Post-Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of a post-processing mechanism in a discharge unit of a printing apparatus increases the risk of paper jams due to reduced discharge height, which exacerbates curling issues in printing media.
Innovation Solution
A control unit is implemented to set print settings that reduce curling in printing media when a post-processing mechanism is installed, allowing for efficient discharge and minimizing paper jams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a post-processing mechanism is installed at the discharge unit, then post-processing functionality is integrated without increasing space, but the discharge height is reduced which increases paper jam risk
Solution Approach 1:
The control unit changes printing parameters (print settings) based on whether a post-processing mechanism is installed. When a post-processing mechanism is detected, the system automatically adjusts print parameters to reduce curling, thereby compensating for the reduced discharge height and minimizing paper jam risk while maintaining integrated post-processing functionality
2Area of stationary object
If a post-processing mechanism is installed at the discharge unit, then space is not increased, but curling of printing medium is exacerbated due to reduced discharge height
Solution Approach 1:
The control unit modifies print parameters (such as print speed, ink density, or heating conditions) when a post-processing mechanism is installed to control and reduce curling of the printing medium. This ensures that even with reduced discharge height, the printing medium maintains acceptable flatness, allowing compact integrated design without compromising print quality

AI summary
An information processing apparatus controlling an inkjet printing apparatus that prints an image on a printing medium and in which a post-processing mechanism that can execute a plurality of types of post-processing processes on the printing medium printed with the image can be installed at a discharge unit that discharges the printing medium, the information processing apparatus comprises a storage unit storing print settings for printing the image that include at least a first print setting, and a second print setting, which is a print setting for one of the post-processing processes and is different from the first print setting; and a control unit that sets the print setting, wherein in a case where the post-processing mechanism is installed, the control unit can set, as a print setting, the second print setting for discharging the printing medium in a state with curling reduced more compared to the first print setting.
