This picture shows a perfect square but the dimensions are 100mm x 70 mm [ For 'murica boys thats... 4 x 2 3/4 inches ] approx

the PC material was 100mm x 70mm as stated. As I recall, they offered several different sizes and I suppose the photo was of PC board of the type they sold.

what type of substrate was used in the production of these boards?

The description now indicates that these are FR-4 boards.

Is this what i need to replace pad where i used braided copper to remove solder and it removed all of it?

This item is a blank circuit board - it's solid copper on one side and nothing on the other. It wouldn't be a suitable replacement for one pad on a circuit board, but it could be used to make a new one.

Has anyone used this to create etchings for intaglio printing?

SORRY CAN'T ANSWER THAT..... I ONLY USE COPPER CLAD BOARDS TO MACHINE THE TRACES AND COMPONET HOLE SIZES ON MY CNC MILL FOR THE PROJECTS I DESIGN ON MY CAD SYSTEM........ THIS METHOD WORKS GREAT FOR ME IN THE EVENT I NEED TO CHANGE SOMETHING......
