If the lettering is a font or vectors, then ideally this would be done in illustration or page layout software, using a white spot colour with the white objects set to overprint and stacked or layered above the original art.

However, if this must be done in Photoshop, then as per my original post you will need to create a spot channel for the white (no need to overprint, Photoshop spot channels behave opposite to all other software and they overprint by default, you have to go out of your way to create a knockout).

So to create the white underbase.

Duplicate all your other layers into a group then merge them. Use the Magic Wand tool to select the empty area. Then click Select>Similiar. Then choose Select>Inverse. Then Edit>Fill and choose white.... click ok.

Move this layer to the bottom of your layers.

And there you have your white base layer that matches the exact shape of your other layers.

I'm not sure if this is what you mean, but you can create a new Layer in the

Layers panel and fill it with white. If you also have a background Layer with say an image on it, you can click on the background Layer (in the Layers panel) to convert it into a normal layer, you can then drag the new white layer (in the Layers panel) under the image layer. That would give you a white layer underbase.

Search for how to create a spot channel in Photoshop (I am presuming that is the route to creating a white under base).
