I saw some tattoo designs in tattoo johny.com which software the tattoo designs are created

I don't see any tattoo designs at search, but regardless, it's doubtful that you'll be able to tell what software they used unless they say so on the site.

Post a link to the site you're referring to so we can check it out.

I believe it was this site they were referring to Rick.

Anyway, tattoo design. There is no good program that is used just to draw tattoos. Chances are these were created using something like Photoshop or Fireworks - programs that allow you to draw vector based images. A lot of them might have also been hand sketches that were then scanned in and "inked" in a drawing program.

In my opinion I would use adobe illustrator cs or cs2 (havent messed with that version too much), I don't know what it is, but I like the way the pen tool on that program operates better than any other graphic program. Real smooth for like tribal type designs.
