Color Reference Guide for Consistent Brand Logo Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Global brand management faces challenges in consistently reproducing corporate logo colors across various regions due to differences in inks, substrates, and printers, requiring a solution to remove human subjectivity and establish a standard for color evaluation in printed products.
Innovation Solution
A color reference guide with multiple calibration pages, each featuring a calibration bar and a color logo of the same design but different hues, is used to calibrate color printers by comparing printed logos against the guide's logos, ensuring consistency in color printing processes like CMYK or G7.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If color printers use different inks, substrates, and printers in various regions, then printing versatility and adaptability are improved, but color consistency and manufacturing precision deteriorate
Solution Approach 1:
The patent applies parameter changes by systematically varying ink formulations, substrate properties, and printing parameters across different regions while maintaining color consistency through standardized reference guides. The calibration process adjusts printing parameters (ink density, halftone screens, trapping) to compensate for regional differences in inks and substrates, enabling versatile printing while preserving color accuracy.
Solution Approach 2:
The color reference guide serves as an intermediary standard between the printer output and the final color evaluation. It mediates the comparison process by providing a physical reference that bridges the gap between different printing systems, allowing operators to objectively assess and adjust color output across various printers, inks, and substrates without direct human subjectivity.
2Ease of operation
If human subjectivity is used in color evaluation, then ease of operation is improved, but measurement precision and reliability deteriorate
Solution Approach 1:
The color reference guide acts as an intermediary physical standard that enables objective color evaluation. Instead of relying directly on human subjective judgment, operators compare printed output against the standardized reference guide, which embodies precise color targets. This intermediary reference removes human subjectivity while maintaining operational simplicity through visual comparison.
Solution Approach 2:
The color reference guide is prepared in advance with precisely calibrated color targets before distribution to printing locations. This preliminary action establishes the color standard beforehand, eliminating the need for complex real-time measurement equipment or highly trained evaluators. Operators simply compare output against the pre-prepared reference, achieving both simplicity and precision.
3Manufacturing precision
If a standardized color evaluation method is implemented across all regions, then color consistency and manufacturing precision are improved, but device complexity and system complexity increase
Solution Approach 1:
The color reference guide is a simplified copy or representation of ideal color standards that can be distributed widely without requiring complex measurement instruments. Instead of deploying sophisticated spectrophotometers or complex calibration systems at each location, the patent uses replicated reference guides that contain the essential color information in an accessible, simple format that can be easily distributed and used across all printing operations.
4Manufacturing precision
If color calibration is performed frequently to maintain consistency, then color accuracy is improved, but productivity and time efficiency deteriorate
Solution Approach 1:
Color calibration data and reference standards are prepared in advance and distributed before printing operations begin. The color reference guides are pre-calibrated and ready for immediate use, eliminating the need for time-consuming on-site calibration procedures. This preliminary preparation enables rapid deployment and minimizes calibration time during production runs.
Solution Approach 2:
The color reference guide provides comprehensive calibration information for multiple printing conditions and color targets in a single reference document. Instead of requiring separate calibration procedures for each color or printing condition, the guide contains excess calibration data covering various scenarios, allowing operators to perform quick visual comparisons without systematic recalibration for each case.

AI summary
A color reference guide is provided for ensuring consistency among color-printed products. The guide can include a plurality of calibration pages and each calibration page can include a calibration bar and a color logo. The calibration bar can be the same on each calibration page and the color logo can be different on each calibration page. A method of providing consistency among color-printed products is also provided and involves comparing a printed logo to a corresponding color logo in the color reference guide. The color reference guide can be used in a variety of printing processes, for example, in a CMYK four-color printing process or in a G7 color printing process. The color reference guide and method are also useful in calibrating a color printer.
