Why?
Because PNG is a lossless raster image format developed for the web, and ultimately for display screens which are RGB.
However the format was never intended or designed to be a print format, and therefore doesn't need to support CMYK colour, and so it's entirely the wrong format to use for CMYK printing - i.e printing where separations are required ...

Broadly speaking there are two schools of thought on file-format design.
One is that you should have lots of options to give lots of different users what they want. The problem with this approach is that compatibility becomes a problem. Just because a program advertises support for tiff files doesn't mean it can open your particular tiff file.
The other is ...

You can switch off anti-aliasing when you export as PNG.
Here's an example

If you are using an older version of PS (prior to CC2015), here's an easy workaround, wihtout the need to install external scripts:

Raster content may be visually clipped for the preview. However, in outline mode, when viewing the construction of the file or its skeleton, raster bounding boxes, which are always a rectangles, will be visible.
If you wish outline mode to precisely match ...

I don't see how anyone could come up with a solution to this. Even if you export in black and white, this may still be a huge file, as PNG is not a practical format at this file size. I'd look at ways to break up the artwork into numbered tiles. Every game, every brochure, every product catalogue, every magazine, etc in the world is made up of pieces which ...
