Script illustrator error 1200

Hi Vanerem,

it would be better if we could find a way to access the default PDF presets indepently from the locale version of Illustrator. I see the similar error with your code when I run it with the German version of Illustrator on Windows 10.:

Error: 1200, an Illustrator error occurred: 1129270854 ('CONF')

That said, let's look into the array of strings that app.PDFPresetsList returns.

With my German Illustrator 2022 this list begins with:

[Illustrator-Standard]
[Qualitativ hochwertiger Druck]
[PDF/X-1a:2001]
[PDF/X-3:2002]
[PDF/X-4:2008]
[Druckausgabequalität]
[Kleinste Dateigröße (PDF 1.6)]
[Kleinste Dateigröße]

So [Smallest File Size] would be app.PDFPresetsList[7].

And [High Quality Print] should be app.PDFPresetsList[1].

But of course the question is: could we reliably build on this order of strings?

And could it be that the order of strings is differently in other localized versions of Illustrator?

If I am using your code the way below, there is no error and the right PDF Export presets are used:

var workingDoc = app.activeDocument;
var workingDocFile = workingDoc.fullName;

var lowResFile = new File( workingDocFile.toString().replace(".ai","_LR.pdf") );

var Options = new PDFSaveOptions();

// populate these with your settings
Options.pDFPreset = app.PDFPresetsList[7];

try{
workingDoc.saveAs( lowResFile , Options );
}catch(e)
{
	$.writeln("Error: "+e.number +", "+ e.message.toString() )
};


var highResFile = new File(workingDocFile.toString().replace(".ai","_HR.pdf"));
var highResOpts = new PDFSaveOptions();

// populate these with your settings
highResOpts.pDFPreset = app.PDFPresetsList[1];

try{
workingDoc.saveAs(highResFile,highResOpts);
}catch(e)
{
	$.writeln("Error: "+e.number +", "+ e.message.toString() )
};

The script works for me, as long as there is a pre-existing .ai file.  It will not work with a new unsaved document. 

Regarding presets, if you click File > Save As, select Save type as "Adobe PDF" and click Save, you should get a "Save Adobe PDF" options window, which should have a dropdown list of Adobe PDF Presets.  You can see whether or not you have [High Quality Print] and [Smallest File Size] or what you have instead.
