How about the halos and “x-ray effect”? Do you see those?
I can see faint halos. If you zoom in on the title that begins “2,100”. The centers of the “00” clearly show halos.
I haven’t seen the x-ray yet.
Not sure if this is the x-ray effect.
If you load the PDF into Illustrator and release the clipping mask, one of the layers consists of the dark gray triangle in the center of the “A” in “USA” for the “USA TODAY” title. When you turn off that triangle in the center of the “A”, the underlying color is very close to the body color of the “A”.
