This whole process requires high contrast printouts from a laser jet printer. I've been experimenting with different methods, and have found that transparencies get a really good resolution, but I believe that printing out on parchment paper
would work even more smoothly. Anyway, the process is that after you print your image (greyscale just doesn't cut it, if you want a tonal range, use a halftone
,) you lay the sheet print side down on your brass and iron it. I put my iron on its highest setting, with no water in it, and press on the image in patches. I press down fairly hard for about thirty seconds, and move up the image in this fashion until the whole image has been covered.
