How do I check in a script that Overprint Preview has already been enabled?

[andyf65867865]

In Adobe Illustrator, is there a way to check the Overprint Preview status (it looks like Overprint Preview is a property of the document) through a script? I have tried catching an error if I try to re-enable it, however that does not work.

try {
  app.executeMenuCommand('ink');
  alert("on");
} catch (e) {
  alert("already enabled");
}

For example, it may be possible to determine this by examining the Window title using AppleScript. When overprint preview is used, the title will include that. It would be a good idea to use ends with it as a criterion, in case the document name includes it.

Not sure if it works correctly in an English environment since the actual environment I tested it in is in another language, but it was successful anyway.

on run
	set is_overprint_preview to false
	tell application "System Events"
		tell application process "Adobe Illustrator"
			set window_title to title of window 1
			if window_title ends with "Overprint Preview) " then
				set is_overprint_preview to true
			end if
		end tell
	end tell
	
	return is_overprint_preview
end run

@sttk3 When you say the Window title you obviously mean a document window title? When I get the window title in JavaScript it does not include info about  overprint preview.

app.activeDocument.name  //test.ai

I didn't know this until just now, but there is a function that returns the current view mode. This solves the problem.

/**

  * @Version 1.0.0

*/

(function() {
  if(app.documents.length <= 0) {return ;}
  var doc = app.documents[0] ;
  alert(isOverprintPreview(doc)) ;
})() ;

/**
  * Returns whether or not overprint preview now
  * @Param {Document} doc target document
  * @Returns {boolean}
*/
function isOverprintPreview(doc) {
  return (doc.getViewMode() === 'OverprintPreview') ;
}

What version of Illustrator will getViewMode() work with ? I didn't find any info about getViewMode function.

Tried it and it seems to be usable from Illustrator 2023.

I checked the pdf documents ADOBE ILLUSTRATOR SCRIPTING REFERENCE: JAVASCRIPT and only the latest versions 2023, 2024, 2025 contain information about getViewMode()
