If you have a color printer, you can choose a color a few shades lighter than what the tabs are now, and use that as a backgrounds color, and black letters of the proper font and size, and print them on an ink jet printer. After that, before you cut them out from the page, spray it well on both sides with clear, gloss polyurethane varnish. Let it dry well, and cut the tabs out. I have used this method for several radios.
