You can do this part digital and part analog. Print out what you want from a computer in white lettering on a black background. Then photograph it with Rollei ATP 1.1 in Kodak D-19. If the film is available in 35mm, it would be perfect for this job, as you would simply need to slip a frame in among the film you are using to make to your contact sheets.

You can also have it appear as a block of white with black lettering if you prefer. Just print out the lettering in black on a light paper, instead of white text on a black ground.
