+1 on the printing.
Another trick you can do if you feel enterprising enough and have the slightest ability in image editing (for reference) my at that time 8 year old niece taught me this trick!!!!....
1)Scan your haggard plate and clean up the image in your editor of choice. Once you're happy with the image, go into the menu and select whatever tool/tab button and invert the image so it reads like you're looking at it in a mirror.
2)Take the file to your local Kinko's print shop and have it LASER printed in the mirrored form in the proper size. Inkjet won't work, but the laser printing will as it deposits on the surface of the paper and the actual media is suitable to the next step.
3)get a piece of aluminum or stainless sheet in the proper dimensions and pre-drill the rivet holes.
Lay your metal down over the image and tape in place on the paper so it won't shift and turn it over. Lay this on a desk or other flat surface and go over it with an iron on high. Do so several times allowing it to cool between passes.
Let the entire thing cool one last time and carefully peal back the paper. If all went well it should peal away leaving the previously inverted image stuck to the metal and readable like normal.
Cover this with clear packing tape, window security film or a good flexible urethane clearcoat.
Once it's dry (or taped) carefully bend to suit and rivet back on the bike.
How'zat?
