Pass-Fail Criteria

ChromaChecker replaces person-dependent visual judgement with a consistent numerical framework. These articles explain the measurement fundamentals, industry standards, and tolerance models that define what “good enough” means in production colour control.

Basics

Understand how subjective colour perception translates into objective numbers — and why precision and accuracy are not the same thing.

Visual Assessment in Numbers
How ChromaChecker converts visual colour judgements into measurable ΔE values the whole team can use.
Basics
Precision vs. Accuracy
Why a consistent but wrong result is different from a variable but centred one — and how each affects your process.

Standards & Norms

Industry-defined pass-fail thresholds used in offset, digital, and brand colour workflows.

Standards & Norms
ISO Standards
ISO 12647-2, 12647-7, and related norms — what they define and how ChromaChecker applies them.
Standards & Norms
Matching Standards
G7, brand-specific tolerances, and how to evaluate colour match against a defined aim point.

Tolerance Settings

Advanced tolerance models that go beyond a single ΔE number.

Tolerance Settings
Snowflake Tolerancing
Define separate limits for L*, a*, and b* axes — tighter where it matters, more lenient where it doesn’t.
