Save opacity as part of swatch

I want several objects to share the same opacity value. I don't want to apply the opacity value to each object individually - instead, I'd like to have opacity saved as part of the objects color swatch, and later change the opacity of all those objects using a single slider of the swatch.

 

Is this possible in InDesign?

You could simply create an Object Style with the Transparency setting to your liking. Apply it to all your objects. If the Fill color should be different simply deactivate the Fill tick box. You can change the Transparency value anytime and all objects with the Object Style applied will change accordingly.

I agree this is a viable solution - however, it would involve adding transparncy to the page and could have unintended consequences on output. But shouldn't be too much of an issue.

 

The problem is that it applies to the entire block - that is everything inside that is given the same opacity.

You couldn't have a block of text in Cyan and then 50% opacity text in the middle of the sentence.

It would be better to have this a 50% tint with overprint applied.

 

Horses for courses.

Further to Peter's advice - https://helpx.adobe.com/ie/indesign/using/tints.html

That's the how to page to create Tint Swatches - they will be based on the Parent swatch.

 

For opacity - set the fill in the object to Overprint - this will let the tint blend with any colour it goes over.

If you don't wnat this to happen - then turn off Overprint for the fill / stroke colour - and the swatch will knockout - which means when it interacts with a colour underneath it will remain the same colour.

The object fill stays opaque, even if I turn on "Overprint Fill" - am I missing something?

Not opacity, which implies you want other objects to show through and is an object-level attribute, but you can create a TINT swatch with your chosen percentage of a color, which is opaque.
