It's great to use a photograph as a "guide print" underneath a piece of glass or acrylic, but expect the printed image to look much more abstract than the photograph.
This 8x10 size photo of a windmill has simple lines that make it a great choice for a mono print for a group art session on symbols of memory. The print size turned out to be too small which made the detail blend together once the paper was pressed onto the acrylic.
Instead of a windmill it created an abstract piece of art. Upside down it gives the feeling of a reflection (or right side up of a cross). The strong symbol works well either way as a background journal page for future reflection. (Image by Maxine)
