SaveAsJPG with CMYK color in subfolder

[SonDaehyeon]

I want to export all *.ai files as *.jpg files.

I tried the code below.

main();

function main() {
  var document = app.activeDocument;

  var outputFolder = new File('/Users/sondaehyeon/Desktop/A')

  var opts = new ExportOptionsJPEG();
  opts.antiAliasing = true;
  opts.horizontalScale = 100;
  opts.verticalScale = 100;
  opts.qualitySetting = 100;

  document.exportFile(outputFolder, ExportType.JPEG, opts)
}

However, the above code has been saved as an RGB JPG file.

But, I need CYMK color.

And I want to go to all the subfolders and work on them.

I'm not sure, but does what happens if you change the document colorspace before exporting?

app.activeDocument.documentColorSpace = DocumentColorSpace.CMYK;

Hi,

ColorModel property is missing for scrripting. You can read below articles

  var tmp = File(Folder.desktop + "/set1.aia");  
  tmp.open('w');  
  tmp.write(act); 
  tmp.close();
  app.loadAction(tmp); 
  app.doScript("act1", "set1", false);  
  app.unloadAction("set1","");
  tmp.remove();
  }

function u16to8(cd) {
  var out =
  (cd < 0x80
  ? toHex2(cd)
  : (cd < 0x800
  ? toHex2(cd >> 6 & 0x1f | 0xc0)
  : toHex2(cd >> 12 | 0xe0) +
  toHex2(cd >> 6 & 0x3f | 0x80)
  ) + toHex2(cd & 0x3f | 0x80)
  );
  return out;
}

function toHex2(num) {
  var out = '0' + num.toString(16);
  return out.slice(-2);
}


var pth = '/Users/sondaehyeon/Desktop/A';
for(var i=0;i<app.documents.length;i++){
    app.activeDocument = app.documents[i];
    exportJPG(pth);
}

Above code will export all ai files that are open in the Illustrator into JPEG with CMYK color model.

Wow! Horrible to have to work around, but amazing! 🙂

Using CMYK jpgs in the real world can be problematic. Most image software expects jpgs to be in RGB and will not display the image correctly.
