How to Confirm the Status of the Graphics Inspection

This article is specific to the integration between VerifyAPI and Esko Automation Engine.

Concept

When you run a graphics inspection via VerifyAPI, there is a parameter in the results metadata (JSON or XML) that states if the inspection was able to find a match and compare the Master and Sample files, or if this match failed:

• graphicsFilesNotComparable

  • false means that the inspection found a graphics match and ran successfully

  • true means that the algorithm wasn’t able to match the master and sample files to run the inspection. When this happens, the PDF report will show 0 results, “No Differences Found”.

How to update your Esko AE workflow to account for this parameter

Step 1: Retrieve the graphics match parameter from the inspection results metadata

• Workflow Parameter: GraphicsNotComparable

• New Value: jsonpath:$.tasks[0].inspectionResult.graphicsFilesNotComparable

Step 2: Add a new router to evaluate the graphics match parameter

Step 3: Configure the workflow state then the inspection match fails

This is just a demonstration of how the error state can be configured; you can reroute the workflow to any task/state that suits your processes.
