Deleting a layer from the layer beneath it.

[Shelly]

I hope I can explain this correctly.  I have an image that i need to turn into a spot white for screen printing on a black poly binder.  I can turn it to white but it loses alot of detail.  In the Affinity Photo file, you will see two layers:  1) BLACK OUTLINE, 2) WHITE. I would like the blackout line layer to be deleted from the white layer so the black poly of the the three ring binder will show through so I do not loose that much detail.  I have also included the orginal PDF I was given to start with.  I am sure there is a much easier way of doing this and I am all ears on how to learn a faster, more efficient way.  If I just use the white layer, the lines are bitmapped and it will not print well.  That's my other problem.

TPG COVER is what I have come up with, but I do not like it.
