I'm about to buy a printer just for edible ink and edible images. While I was checking out the ink prices, I noticed "frosting sheets." How are those different from wafer paper or rice paper?

I don't have a clue...I'd like to know myself.

frosting sheets melt (soften and adhere) into the icing for the most part. They are what I use with my EI printer. Rice paper and wafer papaer are not like frosting sheets in the fact that they do not melt into the icing. HTH

Riec paper and wafer paper are one and the same thing.
Frosting sheets are best to use in a printer.
Rice/wafer has a rough side and a 'smooth' side, but is muich thicker than frosting sheets.
FS are smoother, thinner, and take color much better.

Thanks for the info.!

Also, rice paper starts to curl and lift when it gets damp.

The butterflies that I've used on a couple of my cakes are printed on rice paper (I bought them already printed). I brush them lightly with vegetable oil and they don't curl or get soggy from coming in contact with the frosting.

I use the frosting sheets in my EI printer too and they do take color wonderfully. The only thing I've noticed is blue prints about 2 shades darker than on the printer, so I adjust my images accordingly before I print.

where can I buy frosting sheets, we do not have a cake decorating store in my city.

You can try BakeryCrafts - they have a website.

kopykake and icing images sells frosting sheets also.
