I don't have exact temperature / times for you, but if it's just grosgrain you can also flip the ribbon over so you're pressing down on the back side. That way the heat hits more directly on the back of the ribbon through to the adhesive side of the stones. I would think that would make a pretty good seal. You shouldn't be able to just pick them off. If mine don't seem to be sticking, I just press it longer. You can also try increasing the pressure on the heat press.
