As I understand, to make a good lenticular print you need to have more than 2 offset images (the more, the better). After that the images need to be interlaced and printed and then laminated onto a blank lens.
Apparently, there exist blank frames in which you can just slide the print without laminating but I doubt they will work well.
It all sounds a bit too involved for my liking and no doubt expensive, but intriguing
There are companies that supply software and materials, like this one (I've just done a quick search):
