For gilt chapter ring dials I use clear decal paper, printed at the highest dpi my printer allows without making puddles, photo setting. I lightly swirl sand the bras dial by hand using a burgundy scotchbrite pad. The light swirls give a more gilt look. In the decal pictured, the white is actually clear in use. Most inkjet printers do not print white, so, the brass shows through where the white is.
I used pictures from the internet, then tweaked in my photoshop program. I'm no computer techie, so I did it all the hard way. Made it round, sized, then sharpening all the script by enlarging the picture and smoothing by each pixel. A lot of experimentation, learning what worked and what didn't. I actually enjoyed it, so something must be wrong with me...
