Does anyone have experience using visible light readers with colored (most notably blue shade) ballots. Ian indicated at one point last year that we could print on one specific blue, but apparently you have to order a truck load of the same to make the cost of generating that specific color cost effective. Apparently shoting the ballots with blue ink is also very expensive. Short of striping ballots do we have an answer, for example Georgia that mandates a blue and green color ballot for primaries?Hi John:
We're pretty restrictive on green colors too. For background colors, what is listed in the ballot spec is it.
In order to read blue pen marks, we needed the reader to emit a color of light that absorbs blue. That color of light is red (actually a pumpkin orange). This means that blue (and green ballots) look dark to the reader and it can't see light marks on a dark background.
Frank Kaplan has had experience with color striping. In the past, color striping has made the most economical sense.
