The size of the acetate is around ~A2 size, I got the three acetate sheets printed by printer service for around £35. https://github.com/anfractuosity/rainbow/blob/master/rainbow_pdf.py https://github.com/anfractuosity/rainbow/blob/master/rainbow... is the code that I created to generate the pattern. A home printer may work also though, as they're pretty high resolution these days, I just don't have an inkjet printer at the moment. I'm kind of curious about https://en.wikipedia.org/wiki/Duratrans https://en.wikipedia.org/wiki/Duratrans too, instead of acetate and ink, but they seem very dear.
