I work as a Graphic Designer and restore bicycles. A combination of jobs that led me to a pretty trick way of making new, or re-creating bicycle graphics.
I thought I'd post the process here is case its of some use to someone.
I'm currently restoring a 1956 Dunelt and I know there's no way of tracking down new old stock, or replacement transfers and in any case a lot of graphics from this period were painted. Fortunately, between what was left of the original graphics and google images I found a good reference to start.
So here is what I do.
Step 1. Photograph or google a half decent image of what your trying to create.
Step 2. Re-draw the graphic. Ok, I do this sort of thing everyday but if you've got a basic drawing package and a bit of patience you can soon achieve good results. I'm using the technological route here, but, all of this can be could done by hand with a pencil and scalpel, like the old days!
Step 3. What I end up with on my computer is a 'vector file', a wireframe of the graphic. This type of file can be used with any plotter to cut the vinyl.
Step 4. The cut vinyl. Now I remove the vinyl where I want the paint to go.
Step 5. Obviously I can't remove the backer from the vinyl to stick it down without losing all my detailing bits. So, I apply a backer to the surface of the vinyl, masking tape or any low tack tape will do, rub it down hard. So now the vinyl is in a sandwich, masking tape on top, original backer underneath.
Step 6. I mark a couple of lines on the masking tape side to help with alignment.
Step 7. Now I can remove the vinyl backer, leaving the adhesive of the vinyl exposed.
Step 8. So that the vinyl doesn't 'grab' the surface, I wipe the frame with some soapy water, this enables me to move it into position and check alignment.
Step 9. Wipe down and leave to dry, then remove the masking tape, leaving the vinyl stuck in position. Make sure its completely dry, any water left under the vinyl will suck the paint underneath.
Step 10. Mask up and paint, I usually go for 2 light coats, leave to dry, remove vinyl, job done
The beauty of this is you can cut anything from logo's to pinlines. With some clever masking multi colour is also easy. Or for something amazing…. gold size and gold leaf!!
