2018 watermark experiment, all variants

Media

Four images of our first watermark attempt. The first image shows the item lit as per our usual scanning requirements. The handprint is visible. The second image shows the item lit from underneath. The handprint is clearly visible, but the color of the paper has dramatically changed. Vertical stripes of light corresponding to the placement of the LEDs are visible. The third image is a version of the seond image in grayscale. This makes the stripes from the LEDs even more visible. The final image is the chosen product for this experiment, as seen above.
