Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current color printing systems face challenges in maintaining color stability and consistency across multiple printing devices and substrates, leading to variations in color output that can affect print quality and require frequent recalibration.
Innovation Solution
A digital process control system that includes a central server for managing device link profiles, which automatically measures color targets, compares them to reference values, and adjusts device link profiles to maintain color consistency across different printing devices and substrates, allowing for real-time calibration and reduced need for frequent recalibration.

Engineering Contradiction Analysis
1Reliability
If device link profiles are used for color printing across multiple devices, then color consistency can be maintained, but color variances between different substrates and devices still occur requiring frequent recalibration
Solution Approach 1:
The system creates multiple predetermined device link profiles for different substrate types before printing begins. When a substrate is loaded, the corresponding pre-configured profile is automatically selected, eliminating the need for manual recalibration and ensuring color consistency from the start of each printing job.
Solution Approach 2:
The system adjusts printing parameters by selecting different device link profiles based on substrate characteristics. Each profile contains optimized color transformation parameters specific to particular substrate types, allowing the system to adapt color output without physical recalibration of the printing devices.
2Measurement precision
If manual color calibration is performed for each printing device, then color accuracy can be maintained, but the process becomes time-consuming and complex
Solution Approach 1:
The system creates digital copies of color profiles for different substrate types and stores them in a database. Instead of performing manual calibration procedures, the system retrieves the appropriate pre-measured color profile data, significantly simplifying the process while maintaining color accuracy.
Solution Approach 2:
The system implements a universal color management approach where a single device link profile can serve multiple printing devices. The profiles are designed to be device-agnostic, allowing one profile to be applied across different presses and substrates, reducing the overall complexity of the calibration system.
3Stability of the object's composition
If device link profiles are created for each substrate type, then color consistency across substrates can be achieved, but the number of profiles increases system complexity
Solution Approach 1:
The system introduces a central database as an intermediary between printing devices and device link profiles. This database stores and manages multiple substrate-specific profiles, providing a centralized location for profile storage, retrieval, and version control, which simplifies profile management despite having multiple profiles.
Solution Approach 2:
The system segments the color management process by creating separate device link profiles for different substrate types (e.g., coated, uncoated, glossy, matte). This segmentation allows each profile to be optimized for its specific substrate while the overall system manages them through standardized procedures, reducing complexity through organized division.
