GMI Automation & Scripting 2 — Questions and Answers
Question 1: In a GMI workflow, which scripting approach is best suited for batch-renaming hundreds of graphic output files based on a dynamic naming convention?
- Manual renaming via the OS file manager
- A loop-based shell script iterating over file lists (Correct answer)
- Reprocessing each file individually through the RIP
- Using a static macro recorded once in the application
Correct answer: A loop-based shell script iterating over file lists
A loop-based shell script can iterate over file lists and apply dynamic naming logic at scale efficiently.
Question 2: When automating color profile assignment in a prepress automation script, which data structure is most appropriate for mapping substrate codes to ICC profiles?
- An indexed array sorted by file size
- A key-value dictionary/hash map (Correct answer)
- A flat sequential list
- A binary search tree
Correct answer: A key-value dictionary/hash map
A key-value dictionary maps substrate codes directly to their corresponding ICC profiles for fast lookup.
Question 3: A script that monitors a hot folder and triggers a GMI job ticket when a new file arrives is an example of:
- Polling-based event automation (Correct answer)
- Push-notification scheduling
- Manual queue management
- Static batch processing
Correct answer: Polling-based event automation
Polling-based automation periodically checks a directory for new files and triggers actions upon detection.
Question 4: Which regular expression pattern would correctly match a GMI output filename formatted as 'JOB_12345_CMYK.pdf'?
- JOB_\d+_[A-Z]+\.pdf (Correct answer)
- JOB-\w+-\w+.pdf
- JOB_[a-z]+_cmyk\.pdf
- \w{3}_\d{3}_\w{4}.pdf
Correct answer: JOB_\d+_[A-Z]+\.pdf
The pattern JOB_\d+_[A-Z]+\.pdf matches the literal prefix, digits, uppercase color mode, and .pdf extension.
Question 5: In automation scripting for graphic measures workflows, what is the primary purpose of error handling with try/catch blocks?
- To speed up file rendering
- To prevent unhandled exceptions from crashing the entire batch process (Correct answer)
- To reduce the size of output files
- To enforce color management policies
Correct answer: To prevent unhandled exceptions from crashing the entire batch process
Try/catch blocks intercept runtime errors so a single file failure does not abort the entire batch.
Question 6: A GMI automation script needs to verify that a PDF's bleed is exactly 3mm before processing. Which approach is most reliable?
- Visually inspect the PDF thumbnail
- Parse the PDF's MediaBox and BleedBox values programmatically (Correct answer)
- Check the file size as a proxy for bleed presence
- Ask the operator to confirm via email
Correct answer: Parse the PDF's MediaBox and BleedBox values programmatically
Parsing MediaBox and BleedBox values from the PDF metadata provides an exact, programmatic bleed measurement.
Question 7: When scheduling automated GMI report generation, which cron expression runs a script every weekday at 7:00 AM?
- 0 7 * * 1-5 (Correct answer)
- 7 0 * * 1-7
- 0 7 1-5 * *
- * 7 * * MON-FRI
Correct answer: 0 7 * * 1-5
The cron expression '0 7 * * 1-5' fires at minute 0, hour 7, on days Monday through Friday.
