20 years ago a very wise man named John Warnock came up with a GENUIS idea for a system that would allow files from any computer or application to be viewed or printed on any other computer regardless of whether the other machine had the original software application, fonts, graphics, or anything else. This system which he named Camelot, went on to become the Portable Document File Format released by Adobe in 1993. Since then PDFs have become not only the standard, but in many cases a REQUIREMENT for graphic design and commercial printing professional worldwide.
