Obama certificate falls short in authenticity [has kerning, which is impossible on a typewriter]

Obama certificate falls short in authenticity [has kerning, which is impossible on a typewriter]:

"... the type on the birth document show evidence of 'kerning,' the squeezing of letters into a line so that they intrude into adjacent letter spaces. Kerning is routine, since the advent of word processors and computers, but impossible with a typewriter.

Denninger explains that in the image above, of the name of the hospital, the 'a' and the 'p' share vertical space on the line.

'This process, of course, requires that you know what the next letter is. With a computer this is pretty easy, since the computer can retroactively go back and adjust, and it also can typeset the current letter with the knowledge of what the previous one was,' he reported. 'A typewriter, on the other hand, is a mechanical device. It does not know what the next letter is that you will type, nor does it know what the last letter was that you typed. It thus has a typeface that always leaves physical space between the boundary of each character.'

'To refute this point you must come up with a typewriter that contains a flux capacitor and thus is capable of accurately predicting the future,' he said. 'This document has been assembled by somebody on a computer.'"
