There have been numerous inquiries as to the actual "font" that Signature Plastics uses for their standard keycaps. Over 30 years ago a font was developed, based on a modified IBM standard, using a Gorton engraving machine. Thus our standard font, Gorton Modified was born.There is no electronic file of this particular font, however Arial or Helvetica come very close. Today we can offer 3 additional line fonts - subject to a fee. Check out the link to the left for specifics!
