Architecture & System Design Flashcards

In GMI certification workflows, what is the role of a device link profile within a color measurement architecture?

Answer: To provide a direct transformation between two specific device color spaces without going through a PCS

A device link profile encodes a direct mapping between two device spaces, bypassing the profile connection space for optimized color conversion.

Which architecture best supports A/B comparison of measurement data from two different press configurations?

Answer: Versioned branching data model with shared baseline reference

A versioned branching model stores both configurations' data under a shared baseline, enabling side-by-side delta analysis.

For a large print facility running 24/7, measurement system architecture must include health monitoring. Which monitoring approach provides the earliest warning of impending failure?

Answer: Predictive anomaly detection on metric time-series data

Predictive anomaly detection identifies unusual metric patterns before thresholds are breached, providing earlier warnings than purely reactive rules.

A GMI-compliant system processes measurement data from instruments made by different vendors. The best architectural approach to handle vendor-specific data formats is:

Answer: Implement vendor-specific adapter modules that normalize data to a canonical internal format

Adapter modules translate each vendor's proprietary format into a shared canonical schema, enabling unified processing downstream.

In the context of GMI system design, 'tolerance banding' most directly relates to which architectural concern?

Answer: Defining acceptable measurement deviation thresholds that trigger automated pass/fail decisions

Tolerance banding encodes acceptable delta-E or density deviation ranges so the system can automatically classify measurements as pass or fail.

Which database design choice improves query performance when retrieving historical measurement trends for a specific substrate type over 12 months?

Answer: Indexing on substrate_type and timestamp columns with appropriate query optimization

Indexing on the filter and sort columns (substrate_type, timestamp) dramatically reduces the rows the database must scan for trend queries.

A press measurement system must produce digitally signed reports to satisfy chain-of-custody requirements. Which cryptographic architecture satisfies this need?

Answer: Asymmetric key signing where a private key signs report content and recipients verify with the public key

Asymmetric signing creates a tamper-evident signature that any party with the public key can independently verify, satisfying chain-of-custody integrity.
