Fujifilm Prescale Sample Pack - Super Low LLW (2LW) - Surface Pressure Mapping - Pressure Indicating Film - Tactile Sensor - Pressure Range 70-350 PSI; 3 in. x 4 in. Sheets

First time messing with pressure film. I needed to verify my gaskets on a project are functional since I'm working with curved surfaces and creating saddles to clamp. So I just thought it would be neat to visualize how good or bad my clamps function. The film turns dark pink if the pressure is 100%/passed. It seems software exists to transcribe this into a colorized map. At glance that software looked like it offered a trial period. Seeing that the world in 2026 is all about Ai, I used the example images FujiFilm provides in their product pages and "Vibe Coded" a python script that does the same result. So now that I got the ability to have color mapping with readouts, I opted to buy a couple more sizes of film to play around with!

Size of sample is half of what it’s supposed to be .. 2.5x4 vs advertised 3.5x 5 is 10 in sq vs 17.5. Rep is sending additional film and has corrected advertised sample size.It is monochromatic... just red. You have to send it off for analysis to get colored result. The colored film is 1400psi and over.It works pretty good but you have to send it off for analysis to convert the shades of red to color. You don’t have to take the donor film off after applying pressure so you can tape both pieces down, although it will still be pressure sensitive and may keep developing.All in all it works, just not quite as readable in color as I had thought .
