You really don't know very much, do you?
Here, let me enlighten you. This is my gift to you - a freebie. No strings attached, and I don't want anything for it. What you do with the information is entirely up to you.
This whole "kerning" issue - is the work of a
junior technical writer named Mara Zebest.
This person, who worked on technical documents (software manuals) for Adobe and Microsoft, seems to have
zero knowledge of what happens to the document after she gets done with it.
First of all, the image the White House released is a
compressed image, which means that many of the original details are unrecoverable. If you want the technical stuff, JPG's are compressed with LZW and DCT, and those compressions are
lossy. You have stuff that does the monochrome, and stuff that does the colors. There is
no way you could draw conclusions about the original based on the compressed versions. And Zebest is completely naive about these things, for instance she complains about the difference between the 1 and the 4 in the serial number, but if you inspect the image and run it through the compressions, it turns out the 1 gets assigned to the color layer whereas the 4 ends up being monochrome and therefore gets compressed with JBIG. Stuff like that - I mean, in
no way is this as simple as looking at a smudged area in a print and saying "yep, forgery".
Second, every single one of Mara's "concerns" are
far more likely to be compression artifacts, and most of the time these types of things are encountered in the professional world, they are explained as such unless there is evidence to the contrary. There is no such contrary evidence in this case.
Third, we know that the original image released by the White House was created on a Mac with software not written by Adobe. It seems to me, it would be far more productive to pursue
this trail, rather than wasting any more time on lossy image compression.
But, the birthers seem to have never-ending hope, so I guess Mr. Obama did deliver on at least
half of his promise, eh?
