I have been researching into the possibility of using 'scratch and sniff' on my posters. However, I wasn't sure if it would be possible to produce a scratch and sniff bubble for each of the coffee flavours Nescafe produces for the NDG (Nescafe Dolce Gusto)
My research has informed me that it is possible to produce a scratch and sniff scent for almost any smell. Therefore it wold possible to do this for my poster design.
