GMI Automation & Scripting 3

Question 1

In a prepress automation pipeline, which method is preferred for passing job parameters between scripts to maintain traceability?

Accepted Answer

Using structured job ticket files such as JDF or XML

Answer

Structured job ticket files like JDF or XML provide a documented, auditable record of all job parameters passed between scripts.

Question 2

Which Python library is most commonly used to automate PDF inspection tasks in a GMI scripting environment?

Accepted Answer

PyPDF2 or pikepdf

Answer

PyPDF2 and pikepdf are purpose-built Python libraries for reading, inspecting, and manipulating PDF files.

Question 3

A GMI script processes 500 files sequentially and takes 10 minutes. To reduce runtime, the best architectural change is:

Accepted Answer

Refactor the script to process files in parallel using worker threads or multiprocessing

Answer

Parallelizing file processing across multiple worker threads or processes leverages available CPU cores to reduce total runtime.

Question 4

In automation scripting, what does 'idempotency' mean in the context of GMI job reprocessing?

Accepted Answer

Running the script multiple times on the same input produces the same result without side effects

Answer

An idempotent script safely re-executes on the same input without duplicating outputs or corrupting data.

Question 5

When a GMI automation script needs to log processing results for later auditing, which logging level should be used for successful file completions?

Accepted Answer

INFO

Answer

INFO level is the standard logging level for recording normal, successful operational events.
