In my opinion this is either autopen or secretarial signed.
It appears some form of print. In the two photos shown the signature color is the same as the photo. There is no crossover so not Autopen or secretarial.
I forgot to attach a similar JFK autopen/secretarial to your image.
Unfortunately most of his signed pictures were rarely signed by him.
Genuine examples actually bear little resemblance to autopen or secretarial signed. His signature and writing was imo very sloppy and unreadable at times.
It could be print as indicated by Eric. I am using a Huawei mobile at the moment.
Both Autopen and secretarials would exhibit crossover - the OP does not. Mark, what you posted shows obvious crossover in at least 2 places (crossbar of "J" and also in the "k". I believe the op is a print of some kind.
On a closer examination of the ink your absolutely correct. It's a print.
I was to engrossed with the signature without looking at the obvious.
