Hi Shilpa,
there are 2 ways:
1) To issue shares in share certificate and then send it for dematerialiastion. In this case, you would be required to pay stamp duty as required, as there are physical share certificates, by pasting revenue stamps on the same or by franking with the requisite amount.
2) and Futher directly credit the shares to the Demat of Shareholders or allottees. In this case, no stamp duty will be paid, as no stamp duty will be applicable on the shares in Demat Mode.
These are modes irrespective of premium.
