Printing Device Supply Component Memory for Color Table Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of color management in printing devices, driven by the need to support multiple color spaces, print media, and preferences, leads to memory and storage concerns due to the large size of color tables, particularly in embedded ICC profiles, which can result in overhead and reduced functionality during mass manufacture and customization.
Innovation Solution
A memory device with corrective data that transforms a reference color table into a customized color table, reducing memory consumption by using residual values to modify only necessary nodes, allowing for cost-effective customization and efficient memory use without replacing standard firmware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard color tables are included in firmware for general applicability, then device functionality is improved, but memory consumption and overhead increase
Solution Approach 1:
The color table data is segmented into two parts: a compact reference color table stored in firmware, and device-specific corrective data stored separately in supply components (ink cartridges, drums, etc.). This segmentation allows the firmware to remain small while still supporting multiple color spaces and devices through the interchangeable supply components.
Solution Approach 2:
The device-specific color correction data is extracted from the firmware and placed in replaceable supply components. This extraction reduces firmware memory requirements while maintaining the ability to customize color output for different devices and media types through the supply component corrective data.
2Adaptability or versatility
If comprehensive color tables are stored in firmware to support multiple color spaces and media types, then adaptability is improved, but device complexity increases
Solution Approach 1:
A universal reference color table is stored in firmware that can serve multiple color spaces and device types. Device-specific adaptations are achieved through supply component corrective data, allowing the same firmware to support various color management scenarios without requiring separate firmware versions for each device configuration.
3Measurement precision
If custom color tables are created for each device and media combination, then color accuracy is improved, but manufacturing cost and complexity increase
Solution Approach 1:
Reference color tables are pre-calculated and stored compactly in firmware during manufacturing. Device-specific corrective data is pre-measured and stored in supply components. This preliminary preparation enables accurate color output without requiring complex real-time calculations or extensive customization during device operation or manufacturing.
Solution Approach 2:
Instead of creating entirely new color tables for each device configuration, the system uses a reference color table as a base and applies corrective data from supply components as modifications. This copying approach with adjustments reduces manufacturing complexity while maintaining color accuracy.
