Frame Knockout/Mask

So, I've created an inner stroke to frame an image but what I'd like is for this stroke to knock out the top image and allow an underlying image to show through - is this possible?

I've created this example by making a compound object and placing the underlying image into it to achieve the result, but I'd like to know if this same effect can be created by using an inner stroke and masking/knocking out the top image?

Not sure if this is what you mean

 

 

Here I set to 20pt stroke with Gap set to black too

The with the Attributes Panel open - set the Overprint Gap to be ticked

Then reduce the tint to 0%

 

The overprint Gap gets greyed out for some reason

 

Of course not tested in real world production

But might work

 

Then changing to any colour works

Thanks Eugene
It's kind of what I want to achieve but in your example the inner stroke is overprinting the top image rather than knocking it out to allow the underlying fill/image to show through 100%

Hi @Gavin31332558259u , I don’t think so, maybe someone else will have an idea. Not sure if this is better than your compound object, but you could do it in Photoshop with a mask for the inner stroke:

Thanks Rob

 

This is 100% what I want to achieve but in ID rather than PS

I think you need to make the compound path. Not sure how you made yours, but it’s pretty easy to do with Object>Pathfinder>Exclude Overlap:
