Portuguese to English Art/Literary Printing & Publishing

This is in a reference in a piece of exhibition text citing image references. I understand what it means, ie that the image takes up a whole page.

My question is what is the standard way of referring to this in a similar context in English? I was wondering if 'full plate image' is correct? or is full plate/half plate now archaic?

I also understand that the 'mancha' can refer to text or image - I think images are being referred to here, hence my consideration of 'plate', but is there one term that could cover both possibilities here?

thanks in advance.
