Overlaying a transparent image

[Kirk Bricker]

I have a existing .jpg image of an existing exit from a building. I would like to overlay this image over some new Revit storefront, footing, and floor. I can import the image fine, but the image prints out dark. I have created a transparent effect in Photoshop, and the image is transparent in the view. I have tried to print the sheet with grey scale selected, and color selected with the same results a dark image.
