Light image 40x

Darker image 20x

The signal is a detailed image of a girl’s face with her hair. In photoshop, I overexposed the image, so it would print very faint. The feedback system was a laser printer. I ran the paper through the printer 20 times, and 40 times (the lighter image went through 40 times). The noise that started appearing (difficult to see in digital representations) is random toner that got added to the page and grayed out the paper, and lines where the paper gripper rollers were. after a certain point, the images stopped showing more detail as the paper was reprinted and ended up just becoming more contrasty.
