I recently bought an IBM 6112883 and I would like to use the relegendable keycaps, however I have never done such a thing. I have tried fiddling around in Photoshop, but I cannot figure out a good way to make the relegendable keycaps, and ensure that all of them are the same size (when I print them on paper). I have measured the key below the transparent keycap to be roughly 1.10 x 1.10 cm.
Any help would be appreciated.
