Thermal Printing and Ink fading

Hello,

I am not sure if this is the right subreddit but I would appreciate some help.

Basically I have been trying to accelerate the fading of the ink on thermally printer paper.
“Receipts are typically printed on thermal paper, a chemically coated paper that produces text and image when the heat is applied to its surface. Since this kind of paper is susceptible to heat and UV light, extended exposure to these elements will ultimately cause gradual fading. “

I am trying to work out whether there is something I can apply once to cause the ink to fade within 1-7 days, doesn’t have to be fully. I have read somewhere that I could use scotch tape on, as it has polypropylene in it which would cause what I want or getting polypropylene in pure form and applying that.

If you guys have any other ideas, it would be highly appreciated
Hi Adam,I am researching the same thing. I am looking for a material I could print on that would fade in a few days or weeks, but not years. Ideally I would print stickers. Did you find a solution?Thanks!
