Try hannants.co.uk, they sell decal paper.....or do a decal paper search in the net, maybe USA shops are cheaper, maybe you will find this in India as well.
Depending on the printer and paper quality you can print very good decals.
You need to use a protective varnish though once printed so that the ink wont flow.
You may need both white and transparent paper for the compinations. White letters on transparent is the most difficult issue, you may have to contact proffesional printers.
You will have to cut round the individual decal as well since the varnish will create a continuum on the paper.
