Automated Color Strip Identification via Ink Sequence Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying color measuring strips in offset printing require manual entry of measuring areas by the user, especially when dealing with unknown strip types, which is cumbersome and prone to errors.
Innovation Solution
An automated method using a color measuring instrument with a scanner and computer to determine individual measuring areas of the strip, assign measured color values to printing inks, and compare these values against stored types, allowing for the selection of the most probable strip type without user intervention, utilizing vector calculations in color space for accurate ink assignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual entry of measuring areas is required for unknown color measuring strip types, then the measuring instrument can identify the strip type, but the operation becomes cumbersome and error-prone
Solution Approach 1:
The color measuring instrument automatically performs recognition runs on unknown color measuring strips without requiring manual entry of measuring areas. The system self-identifies the strip type by analyzing the scanned data and comparing it with stored reference data, eliminating the need for user intervention and reducing operational complexity while maintaining high identification accuracy
Solution Approach 2:
The system pre-stores reference data for multiple color measuring strip types in its database. When an unknown strip is encountered, the instrument performs a preliminary recognition run to gather data, then automatically compares this data with the pre-stored references to identify the strip type, avoiding the need for manual configuration
2Extent of automation
If automated recognition run is performed to identify unknown color measuring strips, then manual entry is eliminated, but the system requires certain information about measuring area types to be entered beforehand
Solution Approach 1:
The color measuring instrument is designed with universal functionality to handle multiple types of color measuring strips without requiring specific configuration for each type. The system can perform recognition runs on any unknown strip type by comparing scanned data with a comprehensive database of pre-stored reference data covering various strip configurations
Solution Approach 2:
The system creates digital copies of reference color measuring strip data and stores them in a database. During operation, the instrument scans the unknown strip and compares the scanned copy with stored reference copies to identify the strip type, eliminating the need for manual entry of measuring area types while maintaining automation
3Measurement precision
If multiple color measuring strip types are stored for comparison, then accurate identification is possible, but the data processing and comparison complexity increases
Solution Approach 1:
The system replaces complex manual data processing with automated computer-based algorithms. The measuring instrument's processor automatically compares scanned data with stored reference data using efficient algorithms, reducing the complexity of data processing while maintaining high identification precision through systematic comparison of multiple strip types
Data Source
AI summary
To perform a method for identifying color measuring strips having measuring areas on printed products, the color measuring strips are scanned with a color measuring instrument. The measured color values acquired by the color measuring instrument are stored in a computer and that the measured color values acquired are each assigned to a printing ink. A sequence formed in this way of printing inks is stored in the computer and then compared with color measuring strip types stored in the computer. The stored color measuring strip type having the greatest probability is then selected.
