The embossed seal simply did not come out in a PDF scan.
How do we know that Obama's birth certificate exists?
First, there is the short-form birth certificate. It is generated by a clerk in the Hawaii DOH reading the information in the files and entering it in a computer form. For that to happen there has to be a document in the files. In Obama's case that happened back in 2007 (though it was not published until 2008) when Obama was only a candidate for president---long before he became the leading candidate, much less president. The clerk would have had to have been lying in 2007, and the confirmations by the Republican officials in 2008 would have to be lies as well.
Also, we know that Obama had a birth certificate in 1961 from the notices sent to the newspapers by the DOH in that year.
We know that only the DOH could send those notices in three ways. First because the representative of the newspapers said so, second because the representative of the DOH said so and third because the section of the newspaper was called "Health Bureau Statistic"---which obviously meant that the facts in it came from the Health Bureau, the DOH. In 1961, the DOH was not allowed to issue birth certificates to children born outside of Hawaii, and it only sent birth notices to the papers for children born in Hawaii.
So we know that Obama had a Hawaii birth certificate.
Your claim is that although this certificate exists and although the officials in Hawaii stated that they sent both the short form and the long form version of it to him, and despite a reporter having said that she felt the seal on it--that both the officials in Hawaii and the reporter are lying because the embossed seal does not show up on a PDF scan.
It should be obvious why an embossed seal does not show up on a scan. The light of the scanner is flat from the front and there is no light from the side that highlights the raised parts and lowered parts in the embossed seal. You claim that this is not so, that the scan would show it. Well, back up your claim with some evidence. Show a PDF scan of a Hawaii long form birth certificate that shows the raised seal.
Recently the Conservative secretary of state of Arizona asked Hawaii to confirm that Obama was born there and to confirm other facts on his published birth certificate. Hawaii did, and the Conservative secretary of state of Arizona accepted it as evidence that Obama was born in Hawaii, and ruled that Obama will be on the ballot in Arizona in November.
Only birther "experts"---who have not proven that they are really experts, and who certainly have not shown that they are fair and impartial---have claimed that there is something wrong with Obama's birth certificate. That is two reasons why Ann Coulter, Glenn Beck, the National Review and the Conservative secretary of state of Arizona do not believe them.
Obama's mother lived in Hawaii. Obama's father was studying in Hawaii. There is not a shred of evidence that either of them went from Hawaii to any other country in 1961---and certainly not to Kenya, where the Kenyan government said that it checked on the "born in Kenya" claim and found that it was false.
Hawaii is thousands of miles from any foreign country, and pregnant women rarely traveled late in pregnancy in those days, and yet you and other birthers think that there could be a chance that Obama was born outside of the USA and that the officials of both parties in Hawaii are lying about that fact.
