Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing printing apparatuses face challenges in accurately adjusting the drying temperature of the drying unit to ensure proper drying of the medium, leading to insufficient drying when using a liquid amount corresponding to not-fully dried patches, which affects the quality and integrity of the printed image.
Innovation Solution
An adjustment method is introduced where patches with different liquid amounts are printed and dried, using correspondence data to determine the heating temperature of the drying unit based on the evaporation amount, allowing for proper drying by adjusting the heating temperature to match the desired liquid amount and ensuring full dryness of the medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the discharge rate of liquid is increased for accurate color reproduction, then color accuracy is improved, but the drying capability of the drying unit becomes insufficient leading to inadequate drying
Solution Approach 1:
The patent adjusts the heating temperature of the drying unit as a parameter change to match the liquid discharge amount. By establishing a correspondence relationship between liquid amount and heating temperature, the system dynamically adapts the drying parameters to the printing conditions, ensuring both color accuracy and proper drying without manual intervention.
Solution Approach 2:
The system implements feedback by measuring the actual dry condition of patches with different liquid amounts and using this information to adjust the heating temperature. The correspondence data stores the relationship between liquid amounts and required heating temperatures, enabling the system to learn and adapt to optimal drying conditions based on observed results.
2Reliability
If the heating temperature of the drying unit is increased to dry patches with higher liquid amounts, then drying capability is improved, but patches with lower liquid amounts may become over-dried affecting image quality
Solution Approach 1:
The patent applies local quality by adjusting the heating temperature according to the specific liquid amount in different printing scenarios. Instead of using a fixed high temperature that could over-dry all patches, the system tailors the heating temperature to match the actual liquid discharge amount, ensuring each patch receives appropriate drying treatment without affecting overall image quality.
3Reliability
If the heating temperature is adjusted manually for different liquid amounts, then drying effectiveness is improved, but the operation complexity increases
Solution Approach 1:
The system implements self-service by automatically determining the appropriate heating temperature based on the liquid discharge amount and stored correspondence data. The printing apparatus autonomously adjusts the drying parameters without requiring manual intervention, eliminating the complexity of manual temperature adjustment while maintaining optimal drying effectiveness.
