Subtracted hole looks smaller than the same shape put above
I'm noticing when using the pathfinder subtraction feature I'm getting a loss in pixels in the subtracted object. In this instance I have a design that will be printed on a black shirt. I'm subtracting my top black layer from the layers below. I have attached a screen shot for reference. You can see if you compare the subtracted shape to the top black layer there is a loss of line quality. Basically, you cannot get an EXACT subtraction from one shape to another. Even if you use basic shapes you still have a loss of pixels once subtracted. I've had this problem for as long as I've been using illustrator. The technician on the phone at Adobe was extremely helpful but had all of the same issues on his end. He suggested opening this thread. Hopefully this is something that can be addressed in the next update??

I have this issue from time to time and I have tried EVERYTHING to navigate around it. What am I doing wrong? just trying to subtract the white text from the shape.

This is normal and always was the way AI antialias paths. Treat is as ink spread.

Do you have GPU Preview turned on? In my experience, that does odd things with paths in Illustrator. I'm out of ideas otherwise.

I've outlined the type and expanded the appearance so it is one shape without any stroke on it.

Does the type have a stroke applied to it? If so, it will only subtract the path from the red object and ignore the stroke. If that is the case, you'll need to outline the stroke and then unite the objects then subtract it from the red circle.

So basically I have this shape that I am trying to subtract the white type out of so it is one shape (like a stamp) where the white type is open, not white fill.
When I go to delete the white type from the path, or minus front, or divide, or using the shaper tool (it doesnt matter-same thing happens across the board)- the appearance of the type changes, becoming thinner- but the vector doesn't actually change... it's a visual thing, but its noticeably different.
Not sure if that makes sense or if this has happened to anyone else....
Does anyone know how to fix this or why it's happening?
