Color Gamut Volume Ordering for Print Sample Presentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In print shops, presenting multiple sample prints with varying color gamuts can bias customer perception, making it difficult for them to compare the overall qualities of the samples accurately due to differences in color saturation and gamut volume.
Innovation Solution
A system and method that determine the color gamut volume of each sample print and order them in increasing order of gamut volume for presentation, ensuring that the sample with the smallest gamut volume is presented first and the largest last, using color-measurement patches and data from a color-measurement instrument to adjust the printing configuration and display order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sample prints with different printing configurations are presented to customers, then customers can evaluate various printing options, but color gamut differences among samples create perception bias and make accurate quality comparison difficult
Solution Approach 1:
The system measures the actual color gamut of each sample print using a color-measurement instrument and calculates color gamut volume metrics. Based on these measurements, the system automatically adjusts the presentation order of samples and can modify color rendering to compensate for gamut differences, ensuring that customers evaluate samples based on their printing quality rather than being biased by varying color saturation and gamut volume
Solution Approach 2:
The presentation system dynamically adjusts the order and display parameters of sample prints based on real-time color gamut measurements. The system calculates color gamut volumes for each sample and automatically reorders them to optimize comparison, transforming a static presentation into an adaptive process that responds to the actual color characteristics of each sample
2Ease of operation
If sample prints are arranged in arbitrary order for presentation, then the presentation process is simple, but color gamut differences create bias that prevents accurate quality comparison
Solution Approach 1:
Before presenting samples to customers, the system performs preliminary color gamut measurements and calculations on all sample prints. The color-measurement instrument captures data from each sample, and the system calculates color gamut volumes in advance, then automatically determines the optimal presentation order. This preliminary processing ensures that when samples are presented, they are already optimized for accurate comparison, maintaining simplicity while preserving quality evaluation accuracy

AI summary
An example system includes a processor and a non-transitory computer-readable medium having stored therein instructions that are executable to cause the system to perform various functions. The functions include, for each sample print of a plurality of sample prints, receiving respective color-measurement data indicative of color measurement patches printed on the sample print. The functions also include determining, using the respective color-measurement data for the sample prints, a respective color gamut volume for each sample print. Further, the functions include ordering the sample prints in order of increasing color gamut volume using the respective color gamut volumes for the sample prints. Still further, the functions include providing for display a presentation order for the sample prints, with the sample prints of the plurality of sample prints being arranged in order of increasing color gamut volume.
