Will guys......... I had the local copy shop whip out the above two images at the specified size. The quality of the prints was remarkably good, but the images lost the bright red color seen on the two mock-ups posted.
Things to ponder/consider before trying this..
Size the actual "Viewable" image to display within the frames boarders. I used ½ inch solid black boarder around the image.
Some colors don’t always print like the color you see (No %$#@

) displayed on your PC monitor. My actual printed images lost the brilliant colored red displayed in the mock-ups posted. For this prop idea to work using these images, the red color really needs to be bright.
Ideally, the printed image would look best if it has about ½ inch distance between it and the grill cover. The depth of the filters frame is only enough to “Just Fitâ€
