I have an issue when editing my final work for print in Adobe Illustrator CC regarding Opacity Settings. If I have many groups of objects where the opacity is set on the group level or layer level (so that the opacity setting applies to all objects inside) when I go to do my pathfinder merge function the objects loose their opacity settings.
The reason for this is obvious: they are no longer held within the original layer structure and therefore the opacity settings on objects in the layer structure have been lost and the default is applied.
What I am wondering is the following: is there a way to apply the opacity settings placed on a layer to all objects within it individually? Instead of selecting them all then changing the object opacity manually I would like to just select the layer and apply the appearance effects to all objects within.
I thought expand appearance applied at the layer level may achieve this; but a layer nor a group can have it's opacity effect expanded to the objects within it.
I am creating laser cut print plates and cannot output without resorting to slicing everything with the pathfinder first.
