2 years ago Excellent question. All I ever had is 12mm tapes. But if you look at it, the calibration file is essentially just a pattern of numbered lines that you can print out to see what actually shows up in the printout. I made it with GIMP iirc.
Maybe it is easiest to open it in GIMP and add the additional lines as needed.
how to create the calibrate_12mm_tape.pbm files for 3,5 mm, 6 mm, 9 mm, 12 mm, 18 mm, 24 mm and (36 mm) tape sizes?
