Activate overprint fill to selection / objects / swatches with script.

[AntonioPacheco]

Hi community, I don't really have a code to show for this, but I was trying to find out how to set the overprint fill attribute to my object/selection/swatches, I wrote it like this because I am not sure how does it work, all I know is that to activate overprint filll for text frames is:

text.textRange.characterAttributes.overprintFill = true;

Can anyone help me out with that? Thank you.

(P.s.: I did look at the documentation for scripting but all I found is overprint for pdf files something like that)

Hi @AntonioPacheco, have another look at the docs, for example PathItem has fillOverprint and strokeOverprint properties. - Mark

ohh wow I didn't know about that web page! Normally I use https://ai-scripting.docsforadobe.dev/
Let me take a look.

Yes it has some more up-to-date info, but is almost the same. The page on PathItem seems to be the same.

Thank you so much! I'm reading right now, after that I'll try some for(){} loops to toggle the filloverprint attribute to the pathitems on my selection.

I've been trying for a couple of hours, no results so far but I'll find a way!

Hi! I made this:

var doc = app.activeDocument;
var layers = doc.layers;
doc.artboards.setActiveArtboardIndex(0);
layers.hasSelectedArtwork = true;
for(var i=0; i < doc.selection.length; i++){
doc.selection[i].fillOverprint = true;
}

and in fact it activates the fill overprint attributes, I just don't know why somethines it does not activate for compound path items, but so far... this works! Hope it helps.

You might need some more code to handle CompoundPathItems and GroupItems. For example

if (doc.selection[i].constructor.name == 'CompoundPathItem')
     doc.selection[i].pathItems[0].fillOverprint = true;

And GroupItems have pageItems, so you can do another loop over the group's pathItems and set each of their fillOverprints too.
